InterviewStepping Forward toa World-Class Corporate UniversityAn interview with Chen Jianzhou, Dean of <strong>ZTE</strong> UniversityBy Zhao Lili<strong>ZTE</strong> University stands on the eastcoast of Shenzhen, a prosperouscoastal city in southern China.It is a corporate university founded byleading telecommunication equipmentand network solutions provider, <strong>ZTE</strong>Corporation. Relying on technicalstrength, advanced training facilities,standardized training management,and a team of excellent lecturers, theuniversity has attracted learners fromall over the world who are eager tolearn telecommunications knowledgeand advanced management ideas.Recently, reporter Zhao Lili of <strong>ZTE</strong>TECHNOLOGIES interviewed ChenJianzhou. Now, let’s dive into thiscorporate university on the beautifulseashore.Chen Jianzhou, Dean of <strong>ZTE</strong> University, graduated from TsinghuaUniversity with a master’s degree. He created the <strong>ZTE</strong> HR Center in 1998and <strong>ZTE</strong> University in 2003, and has been honored as one of “China’s First100 Outstanding HR Managers.” He has also acted as Career Mentor forgraduate students of Tsinghua University. He formerly held the positionsof Executive Member of the China Human Resource DevelopmentAssociation, Consultant Director of Human Capital magazine, andConsultant Director of HRCC. In 2009, he was among the Top 10 Winnersof the 4th China Human Resources Management Grand Awards (CEHRA).Clear Orientation Creates BetterValue for Internal and ExternalCustomersD r a w i n g o n m a n y y e a r s o fexperience in the training industry, ChenJianzhou explained three key elementsnecessary for building a corporateuniversity. These elements includecorrect orientation, clear internal andexternal service-driven mechanisms, andcontinual building of core competencyto improve services. So how does <strong>ZTE</strong>University make its orientation clear andimprove its value?Chen Jianzhou told us that the<strong>ZTE</strong> TECHNOLOGIES February 2010
InterviewOur university iscommitted to providingprofessional training,documentation, andconsultancy services to<strong>ZTE</strong> and its cooperators,and to buildstrategic cooperativepartnerships.<strong>ZTE</strong> University in Shenzhenuniversity is committed to providingprofessional training, documentation,and consultancy services to <strong>ZTE</strong> andits cooperators, and to build strategiccooperative partnerships. Currently,the university operates three kinds ofbusinesses: training, documentation, andhotel. The training business comprises<strong>ZTE</strong> staff training, and externalcustomer training, both of which employtechnical and/or management trainingaccording to specific needs.The documentation business alsoconsists of two parts: general userorientateddocumentation and customizeddocumentation. The former is deliveredto customers in conjunction with <strong>ZTE</strong>products, while the latter focuses onspecific projects, and is under full-processmanagement.The last business is our hotel business,which differs from an ordinary hotelbusiness. It offers facilities such asclassrooms, projectors, audio, and printmaterials, thereby satisfying specifictraining needs. <strong>ZTE</strong> University has beenin existence for seven years, and itsresponsibilities have been continuallyexpanded during this time. Apart fromthese three major businesses, <strong>ZTE</strong>University also assists <strong>ZTE</strong> in its efforttowards globalization, which involvesbuilding up an English workingenvironment, implementing Englishcertification, and offering English training.A major change for the university,occurring in 2009, was the introductionof market-oriented services. Marketorientedservices are designed to enhancethe company’s brand image and pushforward its services marketing throughvalue-added training and servicescontracts. “We have attracted income to<strong>ZTE</strong> after promoting service contracts in2009. We have also made contributionstowards furthering the company’sservices marketing; in particular, ourtraining courses on management andadvanced techniques have strengthenedour communication and exchanges withhigh-level customers. The managementtraining we offered to high-level leadersof a telecom operator in China, forexample, played an important role in itsservice transformation, helping them tostrengthen business vitality and improveoperational efficiency,” said ChenJianzhou.In addition to training, documentationalso plays an important role in <strong>ZTE</strong>and partner organizations. Some highendoperators pay great attention todocumentation detail and usually askfor customized documentation. Forexample, in a cooperative projectwith a Hong Kong mobile operator,the university successfully developedcustomized documentation for themthrough project operation management.The project itself was complicated for itinvolved 2G/3G network swapping andconvergence, a feature which posed greatdifficulties to the process of documentproduction. Therefore, the universitypromptly assigned documentationmanagers to the project site and set upa full-process documentation deliveryteam. Employing such joint efforts, theteam was able to supply satisfactorydocuments to the operator.In addition to its external customers,<strong>ZTE</strong> University is also responsiblefor training the company’s staff andmanagement leaders. Training classesare arranged annually for managementleaders at all levels, and have playeda significant role in deepening theirunderstanding and encouraging theimplementation of company policiesand strategies.February 2010<strong>ZTE</strong> TECHNOLOGIES
Learning-Oriented Hotels Open UpNew Business Model OpportunitiesThe hotel industry occupies a centralplace in the working and daily lives ofmany people — especially businesspeople. A person’s time can generallybe spent at home, in the company, or ona journey. When on a journey, peopleusually require the services of a hotel,and commercial hotels are the mostcommon type of hotels used for businessand other purposes.When asked to describe learningorientedhotels, an idea put forward by<strong>ZTE</strong> University, Chen Jianzhou gave us aclear answer. He said that there could bemany types of hotels with different marketorientations, such as commercial hotels,convenience hotels, and learning-orientedhotels. <strong>ZTE</strong>’s learning-oriented hotels aimto create a truly people-oriented learningenvironment that can meet training needs.The concept of learning-oriented hotelsput forward three years ago is different tothat of commercial hotels.Learning-oriented hotels are designedto create a convenient environment forlearners. Signboards inside the hotels,for instance, are different to those inother hotels. The learning-orientedhotel in Dameisha, Shenzhen, has clearsignboards that guide learners from lobbyto classroom, dining room, and guestroom, and provide specific informationabout classes, dining, and rest time. Eachguest room is equipped with referencebooks for learning, and high-speedInternet access, which allows learnersto browse the university website andcommunicate with one another. The hotelalso has a book bar where learners canborrow or check out learning materials.Consumption and entertainment facilitiesunrelated to learning, such as sauna anddepartment stores, are not available in thehotel. Moreover, we are actively exploringnew methods of classroom management,and new designs that will improve ease ofuse in lecture rooms, discussion rooms,and library. Overall, we focus on learningas a key concept when building andoperating our learning-oriented hotels.Strengthening the Construction ofOverseas Training CentersWith the continuous expansion of<strong>ZTE</strong>’s business around the world, theglobalization of training has also become anecessary task, and an important directionof development for <strong>ZTE</strong> University. Ithas been four years since <strong>ZTE</strong> Universitystarted to build overseas training centersin 2005. Overseas training centers notonly facilitate learning for both local <strong>ZTE</strong>employees and overseas customers, butalso contribute to the promotion of skillsof the local population.On this point, Chen Jianzhouprovides valuable insight. First of all, thebusiness of <strong>ZTE</strong> University serves thecompany’s strategy, so its domestic andoverseas operations are in line with thecompany’s strategy. We will continue todevelop overseas training centers basedon the following needs:First, overseas training centers arenecessary to meet the training needsof overseas customers. In most cases,customers require the company to providerelevant technical training when signingcontracts. It is often impractical for thecustomer to send all its employees toChina for training; therefore, 80% ofcustomers ask for local training delivery.This means that in the future, we will needmore of our own facilities, and resourcessuch as teachers, classrooms, organizersand accommodation. Customers fromdeveloping countries sometimes even askus to assist them in establishing their owntechnical centers in a bid to strengthen thecapability of their employees.Second, overseas training centersare necessary to meet the needs of ourcompany. <strong>ZTE</strong> now employs severalthousand international staff in its overseasoffices. They also need to expand theirknowledge and develop relevant skills.However, most are located outside China,so the challenge for <strong>ZTE</strong> University is tomeet their learning needs. Consideringall the differences between countries andlanguages, how should we reasonablyarrange training?Third, there are needs centered ondocumentation. Standardized documentsprovided with each <strong>ZTE</strong> product linehave become incapable of fully meetingthe customization requirements ofour clients. In particular, some highendcustomers require documents tobe exactly consistent with their on-siteequipment. So some documents needto be developed locally. In addition, thecompany’s international employees alsoneed access to documentation, evenif they have already received relevanttraining, as the transmission of routineinformation relies mainly on documents.Fourth, there exists the need to trainoverseas university students. Throughtraining, <strong>ZTE</strong> pools local telecom talentand provides these students with jobopportunities, which also helps expand<strong>ZTE</strong> TECHNOLOGIES February 2010
Interviewthe company’s local brand and reputation.Since 2006, we have established 10overseas training centers in countriesas diverse as Ethiopia, India, France,Brazil, Indonesia, Pakistan, Algeria,Egypt, Columbia and Mexico. Thetraining centers in Ethiopia, India,France and Brazil have also beenupgraded to overseas divisions. They arecalled overseas divisions because theynot only provide standard training, butalso manage document production andother responsibilities of the university.With respect to training bases,besides the Dameisha training base inShenzhen, we will establish new basesin Shanghai, Nanjing, Xi’an and Sanya,China, in 2010 to alleviate the mountingpressure on Shenzhen, and to offergreater convenience and more coursesto learners. We also plan to establishoverseas training bases for the first timein Ethiopia and France.With the gradual development ofoverseas training centers, <strong>ZTE</strong> Universityhas is not only meeting the company’sinternal and external learning andtraining needs, but is also contributingto the improvement of knowledge andemployment among local people. Thecompany’s leader once stated that thebiggest social responsibilities of anenterprise are firstly to pay tax, secondlyto reduce unemployment, and finally tocontribute to the industry and field youare in. In the communications industry,for example, a business’s responsibilitymight be to construct high-qualitycommunications networks worldwide.Apart from this, there also exist othertypes of social responsibilities, such asprotecting the environment.For <strong>ZTE</strong> University, a core socialresponsibility is to train learners andfacilitate the transfer of knowledge.Knowledge is a kind of productive force.China advocates invigorating the countrythrough science and education, the core ofwhich is knowledge. The aim of educationis to cultivate talents, and the core valueof knowledge is reflected through people.This process is dynamic and so mustbe the dissemination of education andtraining. The dissemination of knowledgedrives competition, and is a central tenetof social responsibility. Improving thecapabilities an individual enhances thecapability of a team as a whole, and theoverall capability of society.Take the training center in Bandung,Indonesia as an example. It has beena very successful endeavour. Thecenter trains customers and <strong>ZTE</strong> staff,publicly recruits local learners, andtrains local talents. It has received apositive response from the local society.A great number of university studentsand those seeking re-employment haveall registered actively. As for those withoutstanding academic performance,<strong>ZTE</strong> has chosen to directly hire them. Inthis way, <strong>ZTE</strong> is annually contributingto the development of a large numberof talented individuals within the localBandung area, while providing manyjob opportunities — which has positiveflow-on effects for the wider society.Plans for the Future Based on theVisionSpeaking on the vision and futureplans of <strong>ZTE</strong> University, Chen Jianzhouwas very pragmatic and clear- minded.“<strong>ZTE</strong>’s vision is to become a worldclassenterprise in the telecom industry.As a corporate university within <strong>ZTE</strong>,it also aims to be a first-class corporateuniversity within the industry. Driven bysuch an ambitious goal, we can plan ourfuture in a scientific way. Our universitywill serve as an efficient and advancedknowledge-service platform that candirectly contribute to the company’sbusiness growth. This is our overallorientation,” said Chen Jianzhou. “Onthis platform, we will launch training,documentation, and learning relatedsoftware development, as well asconsultancy services and interactivebusinesses related to knowledgetransfer. It is a challenge for us, becausewe not only need to keep abreast ofthe company’s internal and externalenvironments, but also the most advancedknowledge, methods, and means withinthe telecommunications industry.”Chen Jianzhou added that it is veryimportant for the university to effectivelyintegrate internal and external resourcesto push forward the goal together. Forexample, engaging professionals indeveloping or teaching training coursesis an important consideration. Suchprofessionals might not work in theuniversity, but in another departmentof the company or even outside thecompany. Attracting individuals whoare skilled in both theory and practice to<strong>ZTE</strong> University is a challenge.Indeed, how to integrate all resources,correctly understand internal and externalenvironments, and offer better serviceis a challenge for <strong>ZTE</strong>. Moving intothe future, we intend to stick to ouroriginal development direction, that is,we will continue to actively expand ourknowledge service systems and improvethe capabilities of individuals, whilepressing for the construction of trainingbases at home and abroad. We will setkey projects according to the company’sstrategy and provide high-quality trainingand documentation through our efficientoperations to meet diverse trainingneeds. Moreover, we will activelyexpand our development space, integrateour resources, and pay close attentionto the training field, with the view ofbuilding <strong>ZTE</strong> University into a corporateuniversity of global excellence.February 2010<strong>ZTE</strong> TECHNOLOGIES
FocusA Milestone ofGSM BTSApplication of Multi-Carrier Technology in GSMBy Lv QianhaoEvolution of Broadband GSM BTSGlobal GSM subscriber base is expected to reach a record of 4.2 billion at the end of 2010. As the mostimportant part in the mobile communications system, the GSM EDGE Radio Access Network (GERAN) isadvancing with the evolution of standards and technologies. The growth history of GSM BTS is exactly anepitome of the development of wireless technologies. The current GSM BTS has gone through four stages as shownin Figure 1.<strong>ZTE</strong> TECHNOLOGIES February 2010
FocusGSM is a narrowband digitalcommunications system. Both the1st and 2nd generation GSM BTSadopted the Single-density TRX Unit(STRU). With the miniaturization ofRF components and the developmentof DSP technology, the Dual-densityTRX Unit (DTRU) was widely used inthe 3rd and 4th generation GSM BTS.The dual-density module encapsulatestwo single-density RF modules in oneunit to double the capacity of BTS.However, STRU and DTRU are innature narrowband carrier technology,in which each carrier corresponds to aseparate RF channel.As operators are increasinglyfocusing on lower TCO and smoothevolution, the key for them to survivethe competition is to fast and costeffectivelydeploy or expand theirnetworks. This requirement gives rise1st GenerationGSM BTSGSM Phase1CS BSC199820002nd GenerationGSM BTSGSM Phase2GPRSHRTDM-based BSC2002Figure 1. Growth history of GSM BTS.BasebandProcessingFigure 2.

The 5th generationGSM BTS can provide data rates ofup to 2–4Mbps at the air interface forGSM and support WCDMA, HSPA, oreven LTE. It also supports MIMO andOFDM. The introduction of softwareradio combined with the widebandMulti-Carrier Power Amplifier(MCPA) technology and the reductionin cost help to make a truly SoftwareDefined Radio (SDR) BTS.Introduction of MCPA into GSMThe core of the 5th generation GSMBTS is open architecture based on thewideband multi-carrier technology,in which MCPA is introduced intothe GSM RF module to substitute thetraditional narrowband analog power4th GenerationGSM BTS3GPP R4/R6GERANDual-density CarrierDual-mode BTSRRU+BBUIP-based BSC2006PA5th GenerationGSM BTS3GPP R7/R8EDGE EnhancementDual-density CarrierSDRAll-IP BSC2008Beyondamplifier and achieve broadband RF.As shown in Figure 2, the core ofMCPA is to first couple signals in thedigital Intermediate Frequency (IF)part, and then output them throughthe broadband power amplifier, whichmeans that a physical module canbe software configured as requiredinto many logical radio sub-carrierswithout the need of coupling. Thiswould undoubtedly help to developa low-TCO BTS featuring higherintegration, larger capacity and lowerpower consumption. Moreover,the Digital Pre-Distortion (DPD)technology widely used in WCDMAMCPA can also be widely used inGSM BTS, which will further improvethe service support capacity of GSMBTS and greatly extend the life cycleof GSM network.The multi-carrier technology wascommercialized in WCDMA basestation as early as in 2002, and thenextensively used in CDMA2000 andTD-SCDMA base stations. However,it was not until 2008 that <strong>ZTE</strong> took thelead to introduce it into the GSM field.The reasons lie in technology, cost andstandard restraints. Firstly, WCDMAand CDMA2000 are wideband multicarriersystems, while each carrier inGSM system has only a bandwidth of200kHz. The narrower the bandwidth,the more difficult the design of IF andDigital-to-Analog Converter (DAC).Secondly, due to the higher initial cost,MCPA is not suitable for the widelyusedGSM system. Thirdly, no GSMstandards prior to 3GPP R8 cover themulti-carrier technology.Driven by factors like marketpotential, structure update, costreduction, and standard evolution,major GSM equipment vendorsbegin to pay great attention to thedevelopment of GSM BTS. TheFebruary 2010<strong>ZTE</strong> TECHNOLOGIES
BTS products are evolving to havehigher integration, smaller size,lower power consumption and widerapplication, and to support higherspeeddata services and multi-networkconvergence. The R&D of RF modulehas attracted increasing attention inthe industry, with the view to reducingcost and improving performanceto adapt to the new technologiesand standards. All this leads to theintroduction of MCPA into GSM.Multi-Carrier GSM BTS ― The EdgeTool to Cut TCOFast deployment, green coverageThe typical capacity of a traditionalGSM BTS is 12TRX. The largest dualdensityBTS of the industry launchedby <strong>ZTE</strong> in 2007 has a capacity ofonly 18TRX. After adopting themulti-carrier technology, one MCPAcan support a capacity of six GSMcarriers, three times larger than thetraditional DTRU; and the BTS issmaller in size, which can support36TRX in a single cabinet and 72TRXin a stacked cabinet. The adoption ofthe multi-carrier technology makesit unnecessary to use the hybridcombiner or double filter combiner,and helps to reduce equipmentfailure and insertion loss. Therefore,the multi-carrier GSM BTS has theadvantage of strong coverage over thetraditional one.In addition, the MCPA moduleallows the sharing of power resource,or a power pool, helping to implementdynamic coverage-capacity swappingand improve the coverage area of theBTS.With the help of technologieslike DPD, the efficiency of MCPAhas been further enhanced. BecauseMCPA has a unique carrier pool, itspower resources can be allocateddynamically based on the traffic andthe power needed. This improves theBTS resource utilization. Besides,since MCPA needs no combiner, itspower consumption is greatly reduced.Therefore, the carrier power needed tocover the same area is greatly reduced.For example, the power consumptionThe BTS products are evolving to have higherintegration, smaller size, lower power consumption andwider application, and to support higher-speed dataservices and multi-network convergence.<strong>ZTE</strong> TECHNOLOGIES February 2010

Hence, the goalof fast network deployment and greencoverage can be achieved.Easy O&M, smooth expansionThe MCPA module enables higherBTS integration and fewer BTSs used,which helps to reduce the O&M costand difficulty, and achieve smoothcapacity expansion.For example, a GSM operatoradopted the configuration of S222at t h e initial s tage o f n e tworkconstruction, but later it needs toexpand the configuration to S666 dueto the growing subscriber base.

However,using the MCPA technology, theoperators only needs to configure thesoftware at the O&M center, withoutgoing to the BTS site to add hardwareor modify connection. This wouldundoubtedly reduce the difficulty incapacity expansion and bring greatsavings in labor resource and hardwarecost.Cost-effective evolutionBoth the variety of wirelessstandards and the growing complexityof network deployment have broughttremendous challenges to the longtermand sustainable developmentof operators. Traditional GSM BTSfails to achieve smooth expansionwhile multi-carrier GSM BTS canlay a solid foundation for SDR-basedBTS. The RF Unit (RU) of SDRbaseBTS is software reconfigurableand programmable, which helpsto implement intelligent spectrumallocation and support multiplestandards. The GSM BTS based onwideband multi-carrier technology cansend and receive RF signals of manystandards like GSM, WCDMA andLTE, through software configurationon the 20MHz continuous band. Inpractical networking, the RF modulecan be configured to support GSM/WCDMA dual modes, or WCDMA/LTE dual modes, or GSM/WCDMA/LTE multiple modes, thus realizingcost-effective system integration andevolution.The new-generation SDR-basedBTS solution using the widebandmulti-carrier technology can not onlymeet the operators’ needs for buildingmulti-standard, multi-band networks,but also help them effectively adjusttheir network development strategiesto adapt to the market change andachieve sustained competitiveness andprofitability.Looking into the FutureT h e M C PA - b a s e d G S M B T Swill evolve into a flat Intelligent,Information, and IP-based Base StationSystem (I3BSS), where the functionsof BSC and CN will be integrated intoa master BTS, and a slave BTS will bea low-cost, discrete access point. Thiskind of architecture will further reducenetwork complexity and constructioncost to satisfy the need of a seamlessconverged high-speed data network inthe future.The introduction of advancedtechnologies like MCPA, all-IParchitecture, high-speed DSP andCPRI into GSM makes a true 3GGSM that can boost profitability andlay a solid foundation for a seamlessconverged high-speed broadbandnetwork.10 February 2010 <strong>ZTE</strong> TECHNOLOGIES
DeeperDeeperRAN Sharing,Win-WinBy Xu YiliToday the world is facinga l l k i n d s o f c r i s e s , s u c has the financial crisis, theenvironmental crisis, and the energycrisis. As all the crises deeply influencethe telecom industry, no one can standoutside of them ― Incumbent operatorsare worried about the continued declinein ARPU, higher OPEX and the riskto introduce new services; emergingoperators do not have budget to deploynew networks, especially the RANwith huge CAPEX; governments andtelecom regulators find it difficultyto issue new licenses to encouragecompetition; and consumers hopeto access more value-added servicesat lower fees. All of us are not quitesatisfied with the current telecomenvironment, but how could we do?Deeper network sharing, especiallyt h e R A N s h a r i n g , g i v e s u s a nopportunity to change the telecomindustry into a deeper win-winmodel. Network sharing can have thefollowing benefits:■ Save network OPEX and up to40% of CAPEX on infrastructureequipment;■ Offer a new resource of revenue forincumbent operators;■ Remove market barriers for newoperators;■ Shift the focus of competition fromnetwork deployment cost to serviceinnovation;■ Accelerate network deployment,especially in rural areas;■ Help to build a green network andreduce negative environmentalimpact.Although network sharing has manyattractions, the challenges we have toface are:■ How to share network resourcessuch as frequency spectrum, BTS,BSC, tower, and transmissionfacilities between operators;■ How to operate and maintain theshared network;■ How to independently deliver newservices over the shared network;■ How to allow the access of pre-R6UE to the shared network withoutmessage routing overload;■ How to achieve seamless mobilemanagement;■ How to display the operator’s logoon pre-R6 UE.As a leading global provider oftelecom equipment, <strong>ZTE</strong>can offer flexible networksharing solutions to meetthe various market andcustomer requirements.All solutions are compliantwith the 3GPP specificationsand used in open, multivendorenvironments. Theinnovative solutions <strong>ZTE</strong>has developed canbetter addressthe above challenges.Generally, there are two main formsof RAN sharing: dedicated carrier RANsharing (logic BSC/RNC) and sharedcarrier RAN sharing.The dedicated carrier RAN sharingmode shown in Figure 1 allowsphysical sharing of RAN and a logicaldivision of carriers. It is independent ofterminals, which means that operatorscan have their own subscribers andbrands, while subscribers do notknow whether the network is sharedor not. The operators can broadcastindependent PLMN IDs on their owncarriers, while the UEs only need toaccess CN of the home operator. As theshared BSC/RNC can be connected toother shared BSCs/RNCs or non-sharedBSCs/RNCs, normal handover can beperformed between BSCs/RNCs ofthe same operator to ensure<strong>ZTE</strong> TECHNOLOGIES February 201011

Shared carrier RAN sharing.seamless connection. This mode allowsoperators to independently deployservices in the shared network. Forexample, the operator running highspeedservices can launch HSPA+,while another operator running mobileTV can deploy MBMS on its dedicatedcarrier. Even if they both operatethe same service, they can configuredifferent parameters for the service andthus have different radio performance.Furthermore, the operators canconduct independent configurationand maintenance of their own cells,such as collection of statistics on cellperformance, fault management, andsecurity setting, so that their businesssecrets may not be disclosed.Due to its simplicity in operation,the dedicated carrier RAN sharingmode has prevailed in recent years.In contrast, the shared carrier RANsharing mode, a deeper sharingmode that can provide high spectrumefficiency is more complicated andnot selected by many operators andvendors.The shared carrier RAN sharingmode is shown in Figure 2.

High-PerformanceSDR Base Station FamilyBy Hu YunhuaIn the latest epic disaster film,2012, the world starts to fall apartwith volcanic eruptions, typhoons,seismic catastrophes and meltingglaciers. Notably, it is not aliens or akiller virus that threaten the human racein 2012, but a heating up of Earth’score leading to a shifting of its crust,in other words, climate change. In fact,the issue of rising sea levels caused byglobal warming has been threateningthe human race today. Scientists havewarned that if carbon emissions are noteffectively curtailed, the earth wouldget warmer and warmer, and somecoastal areas would be flooded by theend of the century.In addition to the climate issue, thehuman race is also plagued by energycrisis. Scientists predict that the oil onthe earth will be used up in 50 years,and coal in 100 years at most. Energyshortage has become one of the world’slargest problems.According to Gartner, the ITi n d u s t r y ’s c o n t r i b u t i o n t o t h egreenhouse effect is up to 2% now.With the growing number of basestations and servers in use, the telecomindustry emits more greenhouse gaswhile consuming more energy. At the2009 Mobile Asia Congress, the GSMAssociation (GSMA) announced thelaunch of Mobile’s Green Manifesto,w h i c h h a s b e e n d e v e l o p e d i ncollaboration with The Climate Group.The Green Manifesto shows that themobile industry plans on reducing theglobal greenhouse gas emissions perconnection by 40% by 2020 comparedto 2009. As the number of mobileconnections is set to rise by 70% to 8billion by 2010, the mobile industrycould enable greenhouse gas emissionreductions of 1,150 Mt CO2e in 2020,which is the equivalent of taking one inevery three cars off the road.Energy saving and greenhousegas emission reduction are importantfactors that most operators considerin purchasing mobile base stations.As the life cycle of a telecom standardbecomes shorter and shorter, how toprotect the operators’ investments,h o w t o f a s t c o n s t r u c t a c o s t -effective communication network inunderdeveloped regions, and how toensure the bandwidth for deployingbroadband data services in the futureare the problems equipment vendorshave to consider.In 2008, <strong>ZTE</strong> took the lead tolaunch its SDR series base stations thatadopt innovative distributed structure,unified MicroTCA platform, and multicarriertechnologies to significantlyboost system integration and efficiency,as well as network convergence andevolution capabilities. ZXSDR seriesbase stations support multi-mode,multi-band wireless operation throughsoftware configuration. This not onlysimplifies network structure, but alsoallows powerful evolution to LTE, thusgreatly reducing the costs in equipmentinvestment and network evolution.<strong>ZTE</strong>’s SDR series base stations havefound successful applications withmainstream operators including CSLin Hong Kong, TATA in India andBest in Belaru. The launch of SDRseries base stations makes it easier forGSM operators to build cutting-edgenetworks with smooth evolution toLTE.<strong>ZTE</strong>’s SDR series base stations havethe following advantages:■ Unified SDR hardware platformfor smooth evolution to UMTS/LTE: As the SDR base stationplatform supports various wirelessstandards such as GSM, UMTSand LTE, GSM operators can<strong>ZTE</strong> TECHNOLOGIES February 201013

For example,they can evolve GSM to UMTS/LTE or directly to LTE, withouta n y e q u i p m e n t s w a p p i n g ,which maximally protects theirinvestments.■ Energy saving and environmentfriendliness: The SDR series basestations feature high integration,small footprint, large capacity, andhigh resource utilization. Theyuse the advanced technologieslike intelligent TRX shutdown,intelligent RRU shutdown, PAvoltage adjustment, and TCHmigration to BCCH TRX, to greatlyreduce power consumption.■ Supporting IP networking andmobile broadband evolution: TheSDR series base stations supportIP backhaul and the base stationcontrollers support IP packetswitching. They are used to deliverall-IP networking solutions thatallow mobile and broadbandevolution.■ A full range of SDR base stationsapplicable to various scenarios:The SDR series base stations arecomplete in variety, capable ofproviding optimum solutions forvarious application scenarios.<strong>ZTE</strong>’s SDR base station familyincludes indoor macro base station(ZXSDR BS8800), outdoor macro basestation (ZXSDR BS8900), distributedbase station (ZXSDR BS8700),integrated outdoor micro base station(ZXSDR BS8906), and compact microbase station (ZXSDR BS8908). Eachtype of base station is composed ofthe baseband unit, the RF unit and thecabinet, supporting full-band GSMsingle-mode and full-band GSM/UMTS dual-mode.ZXSDR BS8800It is large in capacity and small insize. It can be used indoors. If usingthe latest RSU82 RF module launchedby <strong>ZTE</strong>, it provides a capacity of up to48TRX in a single cabinet. If added theside cabinet, it supports up to 12 RSUmodules.ZXSDR BS8900It has a capacity as large as that ofZXSDR BS8800, and provides IP55protection for outdoor use. Its cabinetcontains five small shelves that canbe flexibly configured for differentapplication scenarios. For differentsite conditions, it can be used to offerintegrated base station, distributedbase station or BBU+RRU solutions asrequired.ZXSDR BS8700It consists of two parts: BBU andRRU, which can be used either indoorsor outdoors. Such distributed basestation architecture allows flexiblesite selection, zero footprint, extendedcoverage, and baseband pool in hightrafficscenarios.ZXSDR BS8906It can be pole or wall mounted.If using the latest RSU82 module, itprovides the configuration of S44 in asingle cabinet.ZXSDR BS8908It is a compact base station with lowpower consumption, supporting indoor,outdoor and pole-mounted installations.It is less than 14L in size and less than15Kg in weight, and consumes lessthan 200W of power.R e l y i n g o n l a r g e - s c a l ecommercialization of its SDR products,<strong>ZTE</strong> acquired 20.8% market shareof the world GSM wireless mobileequipment in 2009. Its SDR basestations have recorded a total volumeshipment of over 200,000 units as ofOctober 2009. It took <strong>ZTE</strong> almost oneyear to achieve the first 100,000 SDRunits shipped by April 2009, and onlysix months to ship the second 100,000.The fast growth showcases globaloperators’ recognition and favor of<strong>ZTE</strong> as a leading provider of SDR basestations, helping them meet the rapidmarket needs.14 February 2010 <strong>ZTE</strong> TECHNOLOGIES
Innovative, Integratedand EffectiveMRData OptimizationSince firstly appeared in the1990s, GSM has been growingfor 20 years. As it is becomingmore and more mature and robust, itsnetwork optimization methods keepevolving from drive test data analysisto signaling trace analysis, counterbasedperformance data analysis, andto handset-based Measurement Report(MR) data analysis. The optimizationmethods tend to be more intelligent,diversified and more concerned aboutuser speech perception. In particular,the appearance of MR data optimizationhas greatly changed the traditional wayof network optimization, for it canoptimize network performance for eachuser by acquiring and analyzing keyMR data in the call. With a completeanalysis from the macro analysisat the network level to the microanalysis at the user level, the MR dataoptimization is adopted to decodethe private “call password” of eachuser, making it possible to offer userorientedoptimization and enhance userspeech perception.the uplink and downlink level/quality/Time Advance (TA), power, andneighboring cell level during the call,which accurately describes the user’swireless signal environment. However,because of the huge number of users,the daily call measurement reportscontain massive data. To acquireand analyze the massive MR data, ahigher requirement has been raised onsystem architecture and the way of dataacquisition.Different from the hard dataSwitchBIPIEquipmentRoom APCMBIPIBSC V3BIPIBSC V3SwitchBy Chen Hanziacquisition mode commonly adoptedby equipment manufacturers likeEricsson, Nokia Siemens Networks,and Nortel Networks, where MR dataare acquired by hanging a meter on theDigital Distribution Frame (DDF) thatconnects BSC and BTS, <strong>ZTE</strong> adoptsits innovative soft data acquisitionmode (see Figure 1), in which MRdata are acquired directly from BSCand used for the dedicated server.The direct MR data acquisition fromBSC allows simple networking andMR-ServerSUN T5240PCMSwitchBIPIRouterNetworkOptimizationPlatformInnovative Data AcquisitionAs we all know, under the GSMmode, the mobile phone makes ameasurement report every 480ms onEquipmentRoom BBSC V3 BSC V3 BSC V3Figure 1. <strong>ZTE</strong>’s innovative soft MR data acquisition.EquipmentRoom C BSC V3 BSC V3 BSC V3<strong>ZTE</strong> TECHNOLOGIES February 201015
Focuseasy deployment, making it possibleto acquire MR data from multipleequipment rooms and adjust the homelocation of BTS without any effecton MR data acquisition. As a result,the efficiency and stability of dataacquisition has been greatly improved.Integrated Basic DataAcquiring all users’ measurementreports cannot fully satisfy the needof network optimization analysis.We are more concerned about inwhich call events the users make theirmeasurement reports, namely, aboutthe wireless signal environment duringthe key call events, such as mobilephone access, assignment, handover,and disconnection. As these data arenot carried in the measurement reports,they must be provided with the helpof BSC. Through the integrated dataanalysis, an in-depth analysis of eachuser’s CDR, and the simulation of eachuser’s wireless environment duringthe call, we can get the most accuratefirst-hand information for networkoptimization and adjustment.To make basic data as informative aspossible, <strong>ZTE</strong>’s BSC system provideskey information about connection1.

Relational quality/level/TA analysis.point and time for key call eventsduring each user’s call, and gives adetailed explanation for event failureor abnormal connection release.Moreover, the analysis software cansimulate the location where the callis made through a special locationalgorithm to recover to some extentthe whole call process. As a result, allusers in the network can provide their“drive test reports” 24 hours every day.The perfect integration of the data fromBSC and the MR data from the mobilephone provides a basis for analyzinguser call behavior and simulatinguser speech perception, thus makingnetwork optimization more accurateand efficient.Efficient Network Analysis<strong>ZTE</strong> developed its NETMAX, aprofessional network optimization toolthat helps to make all kinds of efficientnetwork analysis.It can acquire relational data of allcells and their related cells throughthe automatic full-band BCCHallocation scheduling and use them asthe basic data to implement networkwidefrequency optimization andneighboring cell optimization.

Third EyeService Delivery PlatformDevelopments in ChinaSeptember 2009By Kevin Wang, Senior Manager of China Services at iSuppliConditions Before the Introductionof SDPs in ChinaIn China, there are three majortelecom players: China Telecom,China Unicom and China Mobile.China Telecom has around 350million fixed line network users.

China Telecom’s service network architecture (pre-SDP deployment).CRBT GWCRBT GW ManagementPlatfomusers. As a result, China Telecom’sexisting service network structure isquite complex (see Figure 1).The service network is made upof separate “silos” and it is verydifficult for China Telecom to achieveits strategic transformation froma conventional telecom providerto a comprehensive informations e r v i c e p r o v i d e r. T h e e x i s t i n gnetwork architecture cannot meet therequirements of end customers, SPs,CPs and of the operator itself. Forexample:■ Customers need a greater choiceof services and of access methods(i.e. one point of access for allnetwork services). They want moreconverged services, plus fraud andprivacy protection from SPs thatabuse the system.<strong>ZTE</strong> TECHNOLOGIES February 201017
Third EyeSMSCStreamingIVRRBT⋯ ⋯Download■ CPs and SPs also suffer from theexisting network platform becausethey require more open networkaccess. They also need lowerbarriers-of-entry for new audio/data/multimedia and convergentservices so they can be introducedmore quickly and easily.■ China Telecom wants unifiedm a n a g e m e n t o f c u s t o m e rinformation and service data. Itaims to develop a general serviceplatform that can avoid duplicatenetwork construction, that canexpand network support for moreservices, and one that strengthensthe supervision of CPs and SPs.China Unicom has dealt with asimilar situation. Before China Unicomlaunched its Service Delivery Platform(SDP), it had over ten different servicemanagement systems (see Figure 2).This complexity made the provisioningand maintenance of value-addedservices difficult and costly. There wasalso a lack of information sharing anda much slower product developmentcycle because of its convoluted networktopology.OCSBSSCRMPRMFigure 2. China Unicom’s service network architecture (pre-SDP deployment).SDP Platform Deployments in ChinaIn order to solve the above problems,and to handle serious competitivethreats, telecom operators in Chinabegan introducing SDPs starting in2006.E q u i p m e n t v e n d o r s , s u c h a sAlcatel, <strong>ZTE</strong>, Huawei, and Ericsson,were active participants since early2004 in creating SDP specificationsand in conducting field trial tests forChina Telecom. After four rounds ofintegration and acceptance testing,domestic vendors produced betterresults than their international peers.<strong>ZTE</strong> gained the largest market share,followed by Huawei. After a year ofnetwork construction, China Telecomcompleted SDP deployments in allprovinces at the end of 2008.China Telecom introduced an SDPplatform into its network by addingan Integrated Service Access Gateway(ISAG) and an Integrated ServiceManagement Platform (ISMP). This newnetwork had a horizontal architecture(see Figure 3). It successfully loweredmarket and technical entry barriers forCPs and SPs by establishing a fast,easy, flexible and dynamic servicedevelopment environment, featuringSession Initiation Protocol (SIP) andApplication Programming Interface(API) support, similar to Parlay X.In the case of China Unicom,Ericsson, <strong>ZTE</strong> and Huawei playedl e a d i n g r o l e s i n s e t t i n g S D Pspecifications, in field trials and inplatform construction for ValueaddedAuthorization Centers (VACs)and WAP portals. <strong>ZTE</strong> has clearlydemonstrated strong innovation inWAP portals.

equirements of end users. It istherefore no surprise that it won thelargest share of WAP portal contractsfrom China Unicom. Although Ericssonentered the SDP market early, technicalsupport delays and a lack of servicemaintenance have caused its marketshare at China Unicom to decline.SDP Project Implementations inChinaSDP project implementations inChina are quite different from othermarkets because of the country’s largepopulation, short project timelines, anddue to the vast scale and complexity ofits national network infrastructure. Astrong project team with good technicalsupport and experience in meetingobjectives quickly is in high demand atthe operator level. Domestic vendors,like <strong>ZTE</strong> and Huawei have significantadvantages. They routinely offerstrong and experienced SDP projectteams with highly-responsive supportfrom their R&D centers in China. Itis clear that they are applying lessonslearned from previous implementationprojects and that they are capable offinding solutions to problems quickly.For example, in March 2008, ChinaTelecom requested a nationwide systemupgrade in about two weeks. Due toa limited maintenance window and alack of unified testing and validation, itneeded equipment vendors to completeall R&D requirements and systemupgrades. Domestic vendors haveclearly excelled at finishing networkupgrades on schedule.SDP Market Share in ChinaIn China, operators generallytend to build SDP systems using adouble-layered architecture. In eachprovince they usually build a singleSDP platform that is interconnectednationally. At China Telecom, eachprovince has deployed a UAG andUMP that is linked with a nationalUAG and UMP counterpart. At ChinaUnicom, each province has built aVAC.Figure 5 indicates the market shareof Ericsson, <strong>ZTE</strong> and Huawei inChina’s SDP market. <strong>ZTE</strong> currently has42% market share, followed by HuaweiSMSCOthers7%A lcatel-Lucent11%StreamingIVRPortalOCSBSSEricsson5%RBTVACCRM⋯ ⋯DownloadPRM<strong>ZTE</strong>42%HW35%Figure 4.

Third Eyeand Alcatel-Lucent.SDP Development Trends in ChinaAfter the deployment of SDPp l a t f o r m s i n C h i n a , n e t w o r karchitectures have shifted fromtraditional vertical designs to horizontalarchitectures. This is allowing newservices to be quickly and easilydeployed within the network. It alsomeans that operators can be more boldand decisive in introducing new servicedeployments based on SDP platforms:■ Enhanced service developmenttools: These can address therequirements of developer atmultiple levels while shortening thetime to market.■ More convergent services: With thetrend towards convergence amongInformation and CommunicationsTe c h n o l o g i e s ( I C T ) b e i n gaccelerated by SDPs, value-addedservices are expected to emerge thatwill create significant new revenuesources for operators and theirpartners.■ More content-based services:In the 3G era, users want moreinformation and entertainmentchoices, so “content is king”. Beingable to rapidly launch new contentwith a flexible pricing system willbe crucial.■ Social networking/communitybased services: These personalizedcontent-based services can bebetter supported using a SDPenvironment.China SDP Platforms ― VendorComparisonEricsson, Alcatel-Lucent, <strong>ZTE</strong>,Nokia Siemens Networks (NSN) andHuawei are the main SDP vendors inChina.

SolutionIPTN Bringsa Green BearerNetworkBy Cheng JianToday, environmental friendliness, energyconservation, and consumption reduction havebecome a global consensus. The best way fora telecom operator to reduce its OPEX is to build agreen network, which is also the major trend of futuretelecom networks. A green network helps to cut tariffrates, reduce environmental pollution, and therebybenefit subscribers. With the development of energyconservation technologies, the telecom industry isstepping into a green era.Core Concept of IPTNWith the deployment of 3G networks andimplementation of full-service operation strategy, theIP-based telecom services place higher requirementson the bandwidth, scheduling, flexibility, cost, andquality of bearer networks. In response to the IPbasedtendency, <strong>ZTE</strong> has launched its new-generationIP-based Packet Transport Network (IPTN) solution(see Figure 1) that uses the open and unified packetswitching platform to carry multiple services, andintegrates the synchronization clock, carrier-classOAM, and protection functions. It is an end-to-endbearer network solution covering the access andconvergence layers and completely catering to the fullservicescenario needs of Mobile Backhaul and FMC.The IPTN solution fully considers the operators’needs for building green bearer networks.

Its green concepts arecharacterized by:■ Energy saving and environmentalfriendliness: It uses smaller-footprintIPTN products that consume fewerresources and emit less harmful gas,effectively reducing OPEX.■ Efficient OAM: It adopts carrierclassOAM technologies and anintelligent network managementplatform to offer refinementmanagement and easy operation andmaintenance, which can improvemaintenance efficiency and lowerOPEX.■ Network security: It supportsmultiple network protectionmechanisms and provides highaccuracytime synchronizationcapability, satisfying the need for asubstitute for GPS while completelyimproving network security andlowering CAPEX and OPEX.■ E v o l u t i o n w i t h I n v e s t m e n tprotection: It supports integratedTDM/ATM/Ethernet/IP bearermode to protect existing networkinvestment; adopts a scalabletechnical platform that can satisfythe needs for smooth standard andservice evolution while loweringCTN 6300CTN 6300Convergence LayerCTN 6300CTN 9000CAPEX.CTN 9000BSC/RNCaGWMSCSGSNMGWMMEOptimized Design for Energy Savingand Environmental FriendlinessThe initial design of <strong>ZTE</strong>’s IPTNproducts is carried out for energysaving and emission reduction, aimingto minimize their pollution to theenvironment.The IPTN product adopts <strong>ZTE</strong>’sself-developed lower-consumptionchip that supports the dormant/standbymode. It uses the Automatic PowerControl (APC) technology and supportsvariable-speed fan control. In addition,it provides intelligent and dynamicadjustment of power consumption thatcan reduce useless power consumptionin the equipment. In the verificationtest for China Mobile’s IP-based MANtransport networks conducted in 2009,the power consumption of <strong>ZTE</strong>’s IPTNproducts was simply one-third of theaverage power consumption of theirkind in the industry.Due to the compact design, theIPTN product is small in size and lowin power consumption, bringing abouteffective space and power savings.ZXCTN 6100 is the most compactpacket transport network platform thatis commercially used at the accesslayer. It is only 1U in height, andthus adapts to the base station accessenvironment flexibly.The IPTN product fully complieswith various international standards onenvironmental protection. Its hardwareplatform is packed by leadless anddegradable materials, complyingwith the RoHS requirements andManagement Regulations on PollutionControl of Electronic InformationProducts. In addition, <strong>ZTE</strong> implementsthe green certification for suppliers, andhas signed a letter of commitment toenvironmental friendliness with them.SDH-like OAM<strong>ZTE</strong>’s IPTN products can save timeand reduce difficulty in OAM. Theyinherit the OAM features of SDH,such as hardware-based hierarchicalOAM, complete performance andalarm detection on pseudo wire, tunneland section layers, fast location ofthe faults of different levels, carrierclassend-to-end management andcascaded monitoring, and high networkavailability.Furthermore, they use the unifiedintelligent network managementplatform (NetNumen T3) that canimplement centralized management ofSDH/MSTP, ASON, WDM, and OTN,and provide NE management and userfriendlyinterfaces for easy end-to-endservice configuration and management.Guarantee for Network Security<strong>ZTE</strong>’s IPTN products have multipleprotection solutions, achieving thecarrier-class reliability of 99.999%. Theredundancy backup is provided for keycomponents at the equipment layer;the Link Aggregation (LAG) and IMAprotection functions are provided at theclient side; multiple protection modes22 February 2010 <strong>ZTE</strong> TECHNOLOGIES
are supported at the network layer.In addition to Label Switched Path(LSP) protection and Sub-NetworkConnection Protection (SNCP), <strong>ZTE</strong>’sIPTN products are the first of their kindto implement the connection-orientedT-MPLS ring network protection (seeFigure 2). With its protection switchingtime less than 50ms, the T-MPLS ringnetwork protection is reliable andsimilar to SDH Multiplex SectionProtection (MSP) that can avoid LSPprotection congestion caused by fiberinterruption. This kind of ring networkprotection has the advantages of simplyconfiguration and high efficiency,which are prominent especially whenthere are a huge number of LSPs. ItsOAM is based on section detection thatcan save more resources than that oftunnel protection.<strong>ZTE</strong>’s IPTN products provideindustry-leading time synchronizationcapability. Most vendors in the industryadopt only the IEEE 1588v2 fortime synchronization. By leveragingthe advantages of various packetsynchronization technologies, <strong>ZTE</strong>took the lead to propose its uniqueEthernet time synchronization solution,that is, to implement the IEEE 1588v2time synchronization based on thesynchronous Ethernet and accuratelyinsert or pick up the timestamp throughhardware so as to effectively reduce the1588v2 packet sending frequency andspeed up the convergence. The solutionhas advantages of high accuracy, highcompensation, and high reliability.Using the SSM or BMC protocols, itcan implement automatic protectionswitching of the time links to guaranteereliable transfer of time signals andsatisfy the need for a substitute forGPS.In April 2008, <strong>ZTE</strong> became thesole vendor to start cooperation withChina Mobile on the PTN-basedGPS substitution, and worked out theTechnical Specifications for PTNbasedTime Synchronization andResearch Report on the Feasibilityof GPS Substitution in TD-SCDMASystem. In August 2008 in Shenzhen,China, <strong>ZTE</strong> completed interconnectionwith the TD-SCDMA base stationand the stress test for PTN-basedtime synchronization for a total of 35nodes. The test results turned out tobe successful, fully conforming to therequirement of TD synchronization. InChina Mobile’s TD-SCDMA networktrials in Shenzhen and Nanjing in2009, <strong>ZTE</strong> adopted its IPTN solutionto transfer time synchronization signalsinstead of GPS clock signals of thebase station. The test results werehighly accepted by China Mobile, lyinga solid foundation for future large scalecommercial use.Multi-Service Bearer Platform forInvestment Protection and SmoothEvolution<strong>ZTE</strong>’s IPTN products provideabundant interfaces including FE, GE,10GE, STM-N (CH, POS, and ATM),TDM E1, and IMA E1, and adopt thePWE3 technology to support integratedTDM/ATM/Ethernet/IP bearer mode,completely satisfying the needs ofvarious service networks while keepingcompatible with existing non-IP basestations to reduce CAPEX.The IPTN products use a scalabletechnology platform that can supportsmooth evolvement of MPLS-TPstandards through software upgrade.Its hardware follows the modulardesign concept; its core nodes enablehigh bandwidth reservation; and itsports can be smoothly upgraded to40G/100G, thereby catering to theneeds of bandwidth expansion andsmooth network evolution.BTSCTN 6100/6200CTN 6300NodeBE1/FECTN 6300NodeBGECTN 6100/6200 CTN 6100/6200eNBE1E1/FECTN 6100/6200Figure 2.

Telecomoperators are seeking to handover theirprivate networks to equipment suppliersfor maintenance so that they can focuson providing more valuable services tosubscribers to maximize the expectedprofits in the era of competition,which gives rise to the concept ofmanaged services. To provide reliableand persistent managed services, theequipment suppliers should be clearabout the challenges for network O&M,as shown in Figure 1.Conventionally, various ElementManagement Systems (EMSs) areinstalled to manage and maintain theirproprietary technology networks. As aresult, these proprietary EMSs have thefollowing obvious drawbacks such aslack of interoperability between EMSs,proprietary GUI style, inconsistencyin management data, difficulties inreport creations, lack of uniformmaintenance flow, and lack of uniformasset management tool. The purpose ofmanaged services is to reduce cost andimprove QoS. As the traditional wayof distributed network O&M fails tomeet the target, the managed servicessupplier must move from distributedO&M to centralized O&M.<strong>ZTE</strong> has rolled out its NetNumenUnified Network Management System(UNMS) that features centralizedsupervision, centralized maintenanceand centralized management. TheNetNumen UNMS has a use case in<strong>ZTE</strong>’s National Network OperationsCentre (NNOC) in India and it is nowproviding top-quality managed servicesin combination with the ElectronicCentralized ManagedServices for MultipleOperatorsPrecise NetworkOperation ReportsFigure 1.

so that the maintenance personnelcan quickly locate and troubleshoot aroot failure. Additionally, the EMSsutilize integrated network informationresources and operate in coordinationwith one another to avoid blindness andimprove O&M efficiency.Dynamic integration with EOMSThe NetNumen UNMS generatesa work order for critical alarms andassociates it automatically to the troubleticket system, and then the work orderis issued and processed. In this way, theself-organized EOMS is established.The fixation of alarm processing flowsin the EOMS accelerates the speed offault handling, improves efficiency ofO&M personnel, and facilitates overallmanagement of service quality as well.Integration with asset managementsystemIn combination with the AssetManagement System (AMS), theN e t N u m e n U N M S p r o v i d e scentralized management of networkassets.

The troubleticket subsystem of the EOMS thencoordinates with all the relevantdepartments for electronic failurehandling. Thus the failure handling iscontrolled in a closed-loop fashion.The AMS is a data center containingall static network resources and otherinventory resource information.Through the specific interface,external systems get their neededdata conveniently. This centralizedmanagement of network resources<strong>ZTE</strong> announced that they have established their first ManagedService Centre in India. The Managed Service Centre—a National NetworkOperations Centre (NNOC) is <strong>ZTE</strong>’s largest outside China and will primarilybe used for offering managed services to Indian telecom operators.Established at an initial investment of USD 4 million, the NNOC will serveto showcase <strong>ZTE</strong>’s superior engineering capabilities to telecom operatorsin India and is in line with the company’s strategy for achieving leadershipin the Indian telecom market.Located in Gurgaon, the NNOC employs over 200 people, 80% ofwhom are local employees from India. The Gurgaon NNOC is integratedwith the <strong>ZTE</strong> Global Customer Support Center (GCSC) in China and theIndia Local Customer Support Center (LCSC) in Bangalore, in order tosupport collaboration and provide back up to each other. Equipped withthe latest equipments and technology from <strong>ZTE</strong>, the NNOC will provide aunified management platform that will help in lowering the Total Cost ofOwnership (TCO) for Indian telecom operators. While Tata Teleservices willbe the first operator to utilize the services of the NNOC, <strong>ZTE</strong> will eventuallyconnect all its customers in India to the centre.helps to increase utilization of networkresources.The UNMS, EOMS and AMS allhave their own report managementmodules that can provide eachoperator with a complete alarm andperformance management report, workorder handling report, and asset usagereport of its various private networks.The maintenance staff can have afull knowledge about the operationcondition of all private networks andreport to the operators about their ownnetwork O&M and Service LevelAgreement (SLA) satisfaction.The NetNumen UNMS for <strong>ZTE</strong>’sNNOC in India implements centralizedmanagement of many private networksfrom different operators. Networkfailures can be located quickly andprecisely through correlation analysis;the maintenance staff only need tocheck the operator interface on theUNMS; EMSs can be left unattendedand maintained in an automatic fashionwithout the operator involvement.Therefore, the valuable expert resourcescan be shared and the cost of manpowercan be cut greatly.ConclusionIn order to fulfill the operators’growing demands for centralizednetwork management, <strong>ZTE</strong> haslaunched its NetNumen UNMSsolution that can help them raisenetwork O&M efficiency, lower theOPEX, reduce customer complaintsand effectively improve their qualityof services.
