News Brief
The Story of LTE in Hong Kong Told at
Mobile World Congress in Barcelona
CSL and ZTE announces details of the first phase of commercial LTE trial in Hong Kong
on CSL’s NextG network
The press conference held by CSL, Telstra and ZTE
February 16, 2010, Barcelona ―
CSL, Hong Kong’s leading mobile
network operator, its parent company
Telstra, and ZTE, unveiled the
milestones achieved since the launch
of NextG, Hong Kong’s leading
mobile network.
In March 2009, CSL unveiled the
commercial launch of NextG, the
award-winning All-IP mobile broadband
network. NextG was the world’s first
SDR-based HSPA+ All-IP network. With
peak download speeds up to 21Mbps and
offering the widest coverage in Hong
Kong, the network provides unrivalled
mobility and performance.
NextG’s SDR capability enables
CSL to rapidly evolve from 3G to
LTE through a software upgrade. This
combined with CSL’s LTE spectrum
(awarded by auction in 2009) means
that CSL has set out a smooth and
readily accessible path to LTE.
In September 2009, CSL, Telstra and
ZTE announced the commencement of
a LTE commercial trial network and
demonstrated speeds up to 127Mbps
utilizing this technology, a first for
Asia and one of the first in the world.
Today, CSL, Telstra and ZTE
announced the progress of the LTE
trial which has seen 20 active and
fully operational LTE cell sites rolled
out in Hong Kong. These sites are
currently being trialed as CSL, Telstra
and ZTE examine the capabilities and
characteristics of the next generation
of mobile technologies.
C S L’s C T O , M r. C h r i s t i a n
Daigneault said, “A unique aspect of
this trial is that it has moved out of
the laboratory and ‘into the streets’.
We are now testing the cell sites with
a ‘consumer ready’ LTE USB modem
and field trials of this are presently
being conducted throughout our LTE
network. We are very pleased with
the results of these trials and the USB
modem is performing extremely
well, showing peak download speeds
upwards of 100Mbps on the streets of
Hong Kong. This means that maybe
we have to revisit the time in which
LTE will be commercially available
and rolled out in networks across the
world.”
The evolution of the LTE network
in Hong Kong has been a hot topic
in the industry over the last year as
CSL and ZTE pioneer new wireless
uses for consumers and enterprises
in the city and position themselves
at the forefront of the global mobile
telecommunications industry.
Tarek Robbiati, Group Managing
Director of Telstra International and
CEO of CSL, also pointed out the
stark changes in usage patterns since
the launch of NextG. Mr. Robbiati
said, “Data traffic has increased by
20 times over that of the legacy 3G
network and has now eclipsed voice
traffic within our network. With the
constant evolution of the network to
higher speeds toward LTE and the
proliferation of Smartphones and other
devices, CSL expects the exponential
growth in data traffic in Hong Kong
to continue for many years. CSL
will continue the investment in LTE
technology to build one of the world’s
most advanced networks in Hong
Kong. This will deliver on our promise
to our customers of a true mobile
broadband service that helps them live
their lives in the way that they want;
in Hong Kong that means on the move
and always connected.”

Seize the Opportunity for
Great Breakthroughs
An interview with Wang Xiyu, Vice President of ZTE Wireless Product R&D Institute
By Fang Li
The year 2009 was the birth
year of 3G in China, and also
a year for ZTE to make great
achievements in wireless business.
The success ZTE has achieved
attributes to the market-driven
R&D concept it has been adhering
to. Since the 3G era, ZTE has been
ranked among global mainstream
mobile equipment suppliers, and has
made massive breakthroughs in the
wireless infrastructure equipment
sector by firmly seizing the market
opportunity to improve its R&D ability.
Recently, reporter Fang Li of ZTE
TECHNOLOGIES interviewed Wang
Xiyu, Vice President of ZTE Wireless
Product R&D Institute.
Wang Xiyu currently serves as Vice President of ZTE Wireless Product R&D
Institute. He joined ZTE in July 1998, and worked successively as Director
of CDMA Product Development Department and Vice General Manager
of ZTE CDMA Division. Drawing on years of experience, Wang Xiyu has
gained a deeper insight into the market and technology development of
wireless infrastructure equipment.
Journalist: At present, cloud computing
and Internet of Things (IOT) have
become hot topics of insiders and the
boundary between communications and
IT industry, or even between IT industry
and other industries is being broken.
How does ZTE view the development
of these hot technologies
Wang Xiyu: Recently, cloud computing
becomes a hot topic among insiders.
ZTE has also paid great attention
to it. Being developed from the IT
field, cloud computing focuses on the
concept of network-based services and
completes storage and computing with
cloud services to save operational costs.
ZTE TECHNOLOGIES March 2010

Interview
Technology
innovation is a
driving force to
enhance product
competitiveness.
ZTE, as a latecomer
to the mobile
communications
market, must strive
to not only keep
up with but also
surpass its rivals
through technology
innovations.
W i t h t h e d e e p e n i n g o f t h e
convergence of communications and
IT industry, cloud services and cloud
storage have been deployed. At the
wireless access side, the traditional base
station structure can not be replaced
by the current cloud computing
technology due to the high real-time
and high bandwidth requirements at
the baseband/RF interface, but the
distributed processing idea of cloud
computing can gradually be used in the
base stations.
IOT has been a focus of attention
in Europe and the United States now.
Chinese operators have also actively
participated in IOT workshops.
C o m p a r e d w i t h t h e p r e v i o u s
communications technology that
could solve interaction of billions of
people, IOT is introduced to solve
interaction of 50 to 100 trillions of
objects. IOT is a very important killer
service of the existing 3G and future
4G technologies. The application of
IOT puts higher requirements not only
on mobile bandwidth but also on realtime
and reliable wireless transmission.
The features of wireless technologies
like broadband, IP-based and flat
structure are provided to meet these
requirements. The wireless signaling
system shall also take into account
some new scenarios brought about by
IOT.
Meanwhile, IOT itself is the
c o n v e r g e n c e o f t h e w i r e l e s s
transmission technology and sensor
technology, and also an important
expansion of the wireless application
technology. ZTE has established IOT
product line and related R&D institute
based on its RFID products. We hope to
rapidly develop advanced technologies
and products in the field of IOT by
leveraging our wealth of experience in
wireless communications.
J: How do you understand technology
innovation Could you tell us about
prominent technology innovations ZTE
has made in the wireless sector
Wang: Technology innovation is
a driving force to enhance product
competitiveness. ZTE, as a latecomer
to the mobile communications market,
must strive to not only keep up with
but also surpass its rivals through
technology innovations. In this way,
we can break the long-term monopoly
by well-known overseas equipment
vendors in the telecom market. In
other words, whether to survive or die
depends on technology innovation.
On the other hand, we should
avoid blind pursuit of technology
innovations. All technology innovations
must be driven by market demands.
Those innovations capable of meeting
customers’ needs are what we need,
while those purely for technology are
not what we want.
Wireless technologies have evolved
at a tremendous rate since 2000. In
the past decade, three generations
of wireless communication systems
(2G/3G/4G) and more than 10 wireless
standards were developed. For a
long time, equipment vendors have
all adopted one wireless standard for
deployment of one type of base stations,
which may result in huge investments
and OAM difficulties. In China alone,
the investments in building mobile
base stations have reached hundreds of
billions yuan.
Due to the great difference in
baseband/RF features of the systems
of different wireless standards, the
Software Defined Radio (SDR)
technology has been found only in labs.
ZTE is the first in the industry to adopt
the combined “soft baseband” and “hard
accelerator” solution to enable baseband
sharing among different wireless

standards. We have also launched a
series of key broadband technologies:
wide bandwidth LDMOS and multiband
broadband transceivers to greatly
increase the carrier density supported
by a single base station, and solve the
coexistence problem of multi-standard,
multi-band wireless systems.
Based on the SDR base station
platform, ZTE took the lead to launch
commercial dual-mode GSM/UMTS
base stations and multi-mode CDMA/
LTE and TD-SCDMA/LTE base
stations. The base stations of multiple
modes can operate on the same physical
platform that allows for unified
management and thus reduces CAPEX
and OPEX. Moreover, ZTE has greatly
widened the application scope and
improved the performance of traditional
cellular networks with a great number
of innovative technologies regarding
air interfaces and radio networking.
The soft base stations launched by ZTE
have brought a great revolution to the
conventional base stations, helping
China move from a follower to a leader
in the field of mobile communications.
Based on the soft base stations, ZTE
has developed a series of technology
innovations: it took the lead to put
forward and realized the notions of
“Super BTS” with large-capacity
baseband pool and “O&M Factory”,
which have fundamentally changed
the construction mode of base stations;
it provided SON key functions such
as automatic upgrade and automatic
configuration for 4G LTE base stations
and took the lead to launch automatic
network planning and optimization
tools for 3G base station systems, which
have brought great OPEX savings for
operators; it succeeded in developing
GoTa―China’s first digital trunking
system with independent IPR―
based on the SDR base stations, and
succeeded in optimizing air interface
standards and redefining network
architecture to make the access time less
than one second and achieve perfect
convergence of traditional wireless
services with radio trunked services;
and it removed the impact of Doppler
frequency shift on CDMA to implement
Air-to-Ground (ATG) communications
across the America.
ZTE has also made innovations in
miniaturizing base stations. It launched
in succession UMTS/CDMA/TD-
SCDMA Remote RF Units (RRU) with
the smallest size and lightest weight in
the industry, which could be mounted
on the wall, fastened to the pole, or
placed on top of the tower to meet the
installation requirements for various
indoor/outdoor scenarios and thus save
a great deal of equipment room space.
Moreover, the adoption of advanced
rack-management technology in the
SDR base station has greatly enhanced
the system’s fault locating capability
and laid a foundation for cost-effective
system expansion in the future.
Clock synchronization is quite
an important issue in the wireless
system. Currently, mobile systems
like CDMA2000, WiMAX, China’s
home-grown TD-SCDMA and its
evolution standard―LTE TDD, are
all relying on the synchronous clock
reference. Traditional clock reference
relied on America GPS. Considering
national security, China developed
the Beidou navigation positioning and
timing system on its own, and now
the complete industrial chain is being
formed. In addition to GPS, the SDR
base station system can also use the
home-made Beidou system solution.
When necessary, it can switch from
the GPS system to the Beidou timing
system.
Due to the high costs of equipment
and engineering of the satellite
receiving system, “IEEE1588V2” is
adopted as an alternative to implement
precise clock synchronization through
the network. Thanks to its unremitting
R&D efforts, ZTE succeeded in
embedding the innovative IEEE1588V2
protocol into the SDR base stations.
ZTE’s self-developed synchronization
algorithm can adapt to both new PTN
and conventional networks deployed
by operators. It supports frequency
and phase synchronization, meeting
the clock requirements of various
wireless systems on the base stations.
The synchronization system was
commercialized in the network of Hong
Kong CSL in 2009. In China Mobile’s
TD-SCDMA testing, it reached the 8ns
timing accuracy.
J: The year 2009 was the birth year of
3G in China, and also a year for ZTE
to make great achievements in wireless
business. Would you tell us what
breakthroughs ZTE has made in its
R&D capabilities behind the continuous
expansion of its market share
Wang: The year 2009 was a year for
ZTE to make great breakthroughs in
wireless business. Our achievements
were made out of years of accumulation.
Now we have reached a brand-new
height in understanding the whole
wireless network framework, core
technologies, networking and customer
needs. It is because the improvement
of our overall capabilities that we can
have a clear understanding of market
needs and launch industry-leading
SDR base station to obtain product
competitiveness.
In 2009, we made great efforts
to promote the High Performance
Product Development (HPPD),
which includes planning in advance,
systematic thinking, coordinated

T h e i m p l e m e n t a t i o n o f H P P D
makes a favorable combination of
product planning and product R&D,
significantly improving both the speed
and quality of R&D. In 2009, the field
quality of our wireless products was
fundamentally enhanced.
We also made groundbreaking
improvements in our platform planning
and architecture capabilities. ZTE is
one of the few vendors in the industry
that can develop a full range of wireless
products. The unified platform it has
developed can not only save R&D
personnel resources but also boost our
overall competitiveness in the wireless
infrastructure segment.
J: Would you please tell us about ZTE’s
patent strategy for the wireless sector
Wang: There are numerous patents
in the telecom industry. Equipment
vendors all hold several related patents,
including basic patents, by participating
in standards drafting and product
development. It is unavoidable for
them to use each other’s patents. The
problem of patent infringement among
them can only be solved by signing
the patent cross-licensing agreement.
Without the equal position to cross
license with the other party, one has to
solve the problem by paying money
or even through legal actions. ZTE
attaches great importance to its patent
strategy for the wireless sector. To date,
it has applied more than 25,000 patents
globally, where over 1,700 patents are
used for the LTE/SAE field.
Our patent strategy for the wireless
field is divided into three stages:
from 1999 to 2003, we improved our
employees’ IPR awareness and the
number of patent applications provided
by each wireless product line; from
2003 to 2009, we focused on patent
quality and formed the basic IPR
defense framework; from 2010 to 2014,
we will significantly improve patent
quality and develop the patent strategy
for certain technical fields, for example,
increase the number of basic patents in
the 3G and LTE fields.
In general, due to its late start in
2G, ZTE has placed the focus of its
patent strategy on 3G/4G and future
evolution of wireless technologies.
And meanwhile, ZTE enjoys promising
prospects in the convergence of 2G/3G/
4G networks.
J: Finally, could you talk about
the development trend of wireless
technologies What is the consideration
of ZTE in this regard
Wang: The essence for developing
wireless technologies is to satisfy
the needs for information interaction
between people, between objects,
and between people and objects. The
emergence of new applications like
IOT has put new requirements on high
availability of wireless data, such as:
■ Higher bandwidth: LTE and LTE
Advanced will provide Gigabit
bandwidth. This puts higher
requirements on combination
efficiency of high-bandwidth
spectrum, intra-cell spectrum and
inter-cell spectrum. Therefore,
Coordinated Multi-Point (CoMP)
transmission and carrier aggregation
are new focuses of research.
■ Higher real-timeliness: The
current transmission delay is
difficult to meet the requirements
for electronic medical care and
real-time experience. In addition to
higher wireless transmission rates
and higher scheduling efficiency of
the base station, high real-timeliness
also requires the entire transmission
network to reduce transmission
delay. Therefore, flat network
architecture is a trend that can
reduce the number of intermediate
transmission and processing nodes
being used.
■ Higher reliability: In the future,
important data demanding high
security, e.g., a vast amount
of electronic payments will be
transmitted over the wireless
network. This needs to ensure
data security and reliability. In
addition to reliable wireless data
transmission, data encryption and
decryption are also important in
wireless technologies.
Furthermore, operators’ needs for
converging multiple networks at low
TCO have posed new challenges for
the form of base stations and their
management. The base stations will
be diverse in variety, from traditional
macro base stations to Pico/Femto
base stations. The development of
components will also have great
impact on the form of base stations.
Nevertheless, wireless base stations
will certainly evolve to be smaller,
broadband-based, flat-based and
collaborative.
To control the future, one has to
control the trend. ZTE has taken into
full consideration the development of
wireless technologies. The marketdriven
R&D mechanism ensures us
to grasp customer needs and trends in
the industry. We have established the
Wireless Standards Department and the
Wireless Pre-R&D Center, and actively
joined the international wireless
standards organizations to track the
development trends of the industry.
And meanwhile, we will share with
industrial partners our views on wireless
development to jointly push forward the
technology evolution.

EPON and GPON, both of
which belong to the same
generation of technology, can
provide 1G/2G bandwidth. With hugestream
broadband services like IPTV,
HDTV, 3DTV and online game play,
subscriber bandwidth requirements
are predicted to increase in magnitude
every five years, accelerating quickly.
The bandwidth requirement per
ZTE TECHNOLOGIES March 2010

Focus
subscriber, for example, is estimated
to reach 50–100Mbps when mid-term
and long-term development trends
are taken into account. However, in
current EPON and GPON interfaces,
bandwidth bottlenecks have begun to
appear. To address this problem, IEEE
and ITU-T have put forward Next-
Generation Passive Optical Network
(NG-PON).
Progress of NG-PON Standards
IEEE 10G EPON
1 0 G E P O N w a s f o r m a l l y
standardized and published in the
IEEE 802.3av in September 2009. The
IEEE 802.3av task force focused on
defining a new physical layer, keeping
the MAC, MAC control and all the
layers above unchanged to the greatest
possible extent. The 802.3av standard
has two core features: it expands the
uplink/downlink bandwidth of the
802.3ah standard to 10Gbps, and it has
good compatibility, allowing for the
coexistence of 10G EPON ONU and
1G EPON ONU on the same ONU.
This provides maximum protection
of the operator’s investment. 10G
EPON—an NG-PON technology
featuring high bandwidth and good
c o m p a t i b i l i t y — w i l l b e w i d e l y
employed in the next few years.
FSAN/ITU-T NG-PON
NG-PON is defined in the ITU-T
G.987 series. NG-PON standardization
is currently being accelerated and
all documentation on XG-PON1
standards are expected to be published
in 2011. The evolution of NG-PON
can be divided by FSAN/ITU-T into
two phases: NG-PON1 and NG-PON2.
NG-PON1 is a mid-term upgrade from
the GPON system, and is backwardly
compatible with existing fiber
installations. It can be further divided
into two generations: XG-PON1 and
XG-PON2, which are differentiated
by the uplink data rate. NG-PON2, on
the other hand, is a long-term solution
with an entirely new optical network
type—such as WDM PON.
ZTE NG-PON Solution
Drawing on a wealth of experience
in access network installations, in
2008, ZTE launched its ZXA10
C300—the world’s first unified NG-
PON platform supporting GPON,
EPON, P2P, as well as the emerging
next generation IEEE 10G EPON and
FSAN/ITU-T NG-PON in a single
shelf. ZTE’s next generation FTTx
solution on the C300 platform offers
the following features:
■ Service provision: It can carry
CATV, IPTV, voice, data, and
mobile services, helping operators
transform themselves into fullservice
providers.
■ Equipment support: It supports up
to 16,384 subscribers in a single
shelf with a maximum reach of
60km; allows mixed insertion
of a variety of PON boards like
GPON, EPON, P2P, 10G EPON,
10G GPON and WDM PON to
ensure smooth evolution to NG-
PON (while protecting operators’
investments); and guarantees QoS,
security control, and Zero-Touch
management and maintenance.
■ Access mode: It supports all major
FTTx access modes including
FTTH, FTTB, FTTC and FTTO.
It also supports mobile backhaul
to meet operator requirements for
various application scenarios.
ZTE 10G EPON
ZTE began pre-research into 10G
EPON as early as 2006. It ascertained
the requirements of major operators
at home and abroad, and cooperated
with PON chip manufactures, optical
module manufacturers, and analog
chip makers to jointly deliver an ideal
10G EPON solution (see Figure 1).
ZTE, one of the leading advocates
of 10G EPON, is actively involved
in drafting 10G EPON standards, and
serves as the editor for IEEE802.3av
10G EPON. So far, it has made over
20 technical contributions and given
100 technical comments in 10G EPON
standardization meetings.
ZTE launched a prototype of the
world’s first 10G EPON equipment
in October 2008. It launched a
commercial trial of asymmetrical 10G
EPON equipment in May 2009, and a
commercial trial of symmetrical 10G
EPON equipment in October 2009. At
present, ZTE’s 10G EPON products
are being commercially used by China
Mobile and China Telecom. These
products have evolved smoothly from
existing xPON equipment, and are
helping the operators greatly enhance
access bandwidth and service access
capabilities of their networks.
ZTE NG-PON
ZTE is also deeply involved in
pre-research work on NG-PON. It
actively participates in drafting NG-
PON standards and serves as the
editor for ITU-T G.987 NG-PON. It
is leading the industry in the research
and development of 10G GPON and
WDM PON.
ZTE has developed prototype
equipment based on the XG-PON1
standard that can meet operator

commercial trial of XG-PON1 cards
based on the ZXA10 C300 platform
in Q3, 2010. Figure 2 shows the
coexistence of GPON and XG-PON.
Furthermore, ZTE has a prototype
of RSOA-based pure WDM PON
equipment and a prototype of hybrid
WDM PON equipment, and plans to
launch the commercial trial of WDM
PON cards based on the ZXA10 C300
platform in Q2, 2010.
Additionally, ZTE has initiated
pre-research work on NG-PON2,
including OCDMA PON, OFDM
PON, and ECDMA PON.

Advantages of ZTE NG-PON Platform
ZTE’s unified NG-PON platform,
ZXA10 C300, has the following
advantages:
■ Lower power consumption and
carbon footprint: ZXA10 C300
can reduce power consumption by
41% due to ASIC & PCB design
and innovative methods of setting
boards, ports and modules at idle
status.
■ Higher site savings: ZXA10 C300
offers a higher density of PON
modules, allowing 16,384 users
to share the same platform. It
also offers longer coverage with
a range up to 60km. Compared to
traditional OLT designs, ZXA10
10G EPON ONU

10G EPON ONU
C300 combines the benefits of
density and coverage to provide
higher OPEX savings (as fewer

■ F u t u r e p r o o f n e s s : S m o o t h
evolution to 10G EPON and/or
NG-PON is possible with ZXA10
C300; only one new module is
needed for the upgrade to 10G
EPON or NG-PON. This enables

Mature OAM:
A Powerful Boost for 10G EPON
By Zhu Zhenghua
The maturing of EPON standards
and technologies has ushered in
large-scale commercialization
of EPON networks. Today, EPON
installations in China have exceeded 20
million lines. Being the leading EPON
supplier in China, ZTE can deliver
mature OAM solutions in light of the
new characteristics of EPON networks.
ZTE has been integrating the
research of FTTx OAM into its
development of PON products. Its
EPON OAM solution, drawing on
years of field research experience,
is highly recognized in China. It
is helping Chinese operators push
forward the construction of FTTx
optical broadband access networks.
ZTE’s EPON OAM solution offers the
following advantages:
■ Equipment commissioning: It
supports Plug and Play (PnP)
functionality, fast and zero touch
deployment, easy management
address planning and configuration,
and needs little change in the case
of equipment failure.
■ Service provisioning: It supports
multi-service configuration, as
well as fast, centralized and batch
service provisioning.
■ Equipment management: It supports
unified equipment management.
The management system is easy to
operate and has high performance.
■ Service assurance: It provides
e a r l y f a u l t w a r n i n g , r e m o t e
fault diagnosis, and remote fault
handling.
■ Network monitoring: It provides
remote equipment monitoring and
operation environment monitoring.
■ Network security: It provides
equipment authentication, port
location, user binding and user
query.
The 10G EPON standards are
derived from EPON standards. The
IEEE 802.3av 10G EPON Task Force
has taken into full consideration
wavelength planning, control protocols,
and management mechanisms in
drafting the 10G EPON standards.
Except for the expanded EPON MPCP
protocol (IEEE802.3) and additional
10Gbps capability notification and
negotiation mechanism, 10G EPON
inherits almost all of the EPON
standards, so it makes full use of the
EPON OAM solution.
S i n c e 1 0 G E P O N a l l o w s
compatibility with and migration from
legacy EPON networks, it is natural for
a 10G EPON OAM solution to emerge
from the basis of mature EPON OAM.
10G EPON and EPON have similar
service models
As 10G EPON is similar to EPON
in terms of equipment type, application
scenario, VLAN model, and service
identifier mapping, it is easy to learn
and accept the service model of 10G
EPON. Various types of ONU devices
including SFU, HGU, SBU, MDU, and
MTU, are recognized in the telecom
market as useful in different application
scenarios. These EPON ONU devices
can be used for 10G EPON when
their interface definitions are slightly
modified. The service model and user
model of EPON can also be used for
10G EPON.
10G EPON and EPON have similar
service data
The configuration, performance and
alarm data of 10G EPON and EPON
are defined in the same specification.
Their service models are simple, with
relevant data being added to 10G

EPON. EPON has a well-defined
fault diagnosis function, which can
be used in 10G EPON after changing
the precision and scope of relevant
data. In the EPON specifications, three
bandwidth types are defined: fixed
bandwidth, assured bandwidth, and
best effort bandwidth. These bandwidth
types are also defined in 10G EPON—
except a few modifications are made
to the data concerning bandwidth,
precision and step size for Dynamic
Bandwidth Allocation (DBA). The
configuration, performance, and alarm
data of EPON can also be used in 10G
EPON after a few modifications have
been made.
10G EPON and EPON have the same
authentication mode and the same
service fulfillment flow

As shown in Figure 1, EPON ONUs
are managed in three modes: extended
OAM, extended OAM and SNMP,
and extended OAM and TR069. These
management modes can be used
for 10G EPON only by adding the
extended OAM definition related to
10G EPON.
As the northbound interfaces of
10G EPON are fully compatible with
those of EPON, all EPON interface
parameters can be used for 10G EPON.
As a result, the whole OAM flow of
10G EPON remains unchanged without
the need to develop new interfaces or
alter its service support system.
10G EPON leverages the simplicity,

low cost, and mature industrial chain of
the EPON and Ethernet technologies,
and its large-scale commercialization
is just around the corner. Global
mainstream operators have predicted
that 10G EPON will see widespread
commercial installation within one
year, and its technologies and industrial
chain will experience booming growth.
C u r r e n t l y, m a j o r o p e r a t o r s
worldwide are paying increasing
attention to 10G EPON. Some of
them—like Japan’s NTT DoCoMo,
Korea’s KT, France Telecom, Telecom
Italia, and Taiwan’s Chunghwa
Telecom—are conducting 10G EPON
technology and equipment assessment,
and some of them have even run 10G
EPON field trials.
Thanks to the strong affinity between
10G EPON and EPON, the 10G EPON
OAM solution based on mature EPON
OAM can effectively guarantee the
smooth commercialization of 10G
EPON.

Elisa VDSL2 Leads
Finland’s Broadband Market
By Xue Qikang
With more than 2.2 million
mobile subscribers and
1.3 million fixed line
subscribers, Elisa is Finland’s second
largest operator of integrated services.
It also leads the Finnish broadband
market with over 513,000 broadband
subscribers.
E x i s t i n g A D S L 2 + n e t w o r k s ,
however, cannot meet increasing
bandwidth demands, and the emerging
FTTH faces enormous investment
pressure. Governments and operators
in Finland are therefore seeking
better solutions for the accessibility
of feature-rich high-speed broadband
services in order to retain home users
and local enterprise users.
Faced with new market competition
during the global economic crisis, Elisa
chose to cooperate with ZTE in 2008
to deploy a new broadband access
platform.
With the rapid development of
carrier-class broadband technologies
and the explosive growth of their
subscriber base and network traffic,
Elisa hopes to deliver full, high quality
services to its customers. VDSL2 is
a new broadband access technology
that is compatible with ADSL2+ and
supports up to 100M uplink/downlink
bandwidth. As VDSL2 can be used
to offer ultra-high bandwidth—
while saving operators’ investment
in subscriber loops—it has become
an ideal choice for last mile access.
ZXDSL 9806H, ZTE’s award-winning
VDSL2 DSLAM equipment, was
chosen by Elisa to deliver quality
broadband services for the following
reasons:
First, ZXDSL 9806H is capacity
and networking versatile. It provides
ADSL, ADSL2+, SHDSL, VDSL2,
and LAN ports at the user side, and GE
uplink ports at the network side. It also
supports uplink PON such as uplink
EPON, GPON, 10G EPON, and 10G
GPON ports. With the development
of video services, ZXDSL 9806H will
incorporate more functions. It can be
flexibly installed due to its compact size
and high density features, and is ideal
for small spaces, outdoor environments,
and residential or business buildings.
Second, ZXDSL 9806H has low
12 March 2010 ZTE TECHNOLOGIES

it can provide a QoS guarantee. This
minimizes Elisa’s operating expenditure
(OPEX). The successful application
of ZTE’s VDSL2 for UMTS backhaul
has helped Elisa achieve true fixed and
mobile convergence (FMC) in service
delivery and maintenance.
Finally, as the recipient of many
prestigious awards, ZXDSL 9806H
is highly regarded by operators
around the world. It was awarded the
Infovision Award at the Broadband
World Forum Europe in Berlin, October
2007; the Convergence World Award
at the SOFNET Forum in London,
April 2008; and was awarded the top
ranking in Current Analysis’s product
performance evaluation report in the
Global Remote DSLAMs category in
2009.
VDSL2 is a new generation DSL
technology, and has been widely
adopted by telecom operators and
internet providers in Finland and even
the whole of Europe. By cooperating
with ZTE, Elisa has deployed a new
VDSL2 platform that can deliver
high-quality broadband services
with lower OPEX and greatly boost
its competitiveness in the Finnish
broadband market. Elisa has signed a
five-year global procurement contract
with ZTE, and has been devoted to
building leading-edge broadband access
platforms for its customers around the
globe.

power consumption. The results of tests
performed by multiple operators show
that ZXDSL 9806H is environmentally
f r i e n d l y. A s a n e x t - g e n e r a t i o n
integrated broadband access device, it
has the lowest power consumption of
all products of its kind in the industry.
Its power consumption is far lower
than that set by the European Union,
and this can be attributed to ZTE’s indepth
research into system architecture,
cooling, and power management.
Third, ZXDSL 9806H supports
mobile backhaul. It can be used for
UMTS backhaul service transmission,
which allows fast deployment of mobile
broadband services between newly
established base stations. Although it
adopts economic packet transmission,
ZTE’s broadband access product—the ZXDSL 9806H—was given the
top ranking in Current Analysis’ recent product performance evaluation
report in the Global Remote DSLAMs category. The ZXDSL 9806H recorded
the highest ratings in five purchase pre-set criteria by Current Analysis, a
leading independent research firm.
For its excellent performance, ZTE’s ZXDSL 9806H topped the
performance evaluation compared with other vendors’ similar products
in five major areas: Density, Network Uplinks/FTTN Capability, Video
support, POTS support and pricing. Its unique design significantly
helps protect operators’ existing investments and maximize revenues
associated to new broadband services, including video-on-demand, IPTV,
and Internet games.
ZTE’s 9806H provides up to 96 ADSL2+ lines or 64 VDSL2 lines in
a 2U rack design, which can be easily deployed near the customers’
location, hence seamlessly connecting it with multiple DSLs to a highspeed
internet line using multiplexing techniques. This broadband
system is perfectly ideal for FTTx network architecture model and enables
operators to build next-generation broadband network while reusing
existing copper cables.

Future-Oriented Green
FTTx Solution
By Chen Yi
With the development of
information technologies
in recent years, user needs
have expanded from simple voice
to a multiplay of voice, video, data
and images. An increasing number
of users are paying attention to new
broadband services, such as IPTV,
VOD, online games, e-learning,
video conferencing and video phone,
and these place greater demands on
network bandwidth, QoS and security.
Value-added services have also become
an important means for operators to
attract users and increase their income.
The growth of these new services
has led to increasing bandwidth
demands at the access layer. With
the development and convergence of
core networks, broadband access and
sustainable evolution have become
crucial in network construction. Also,
with technological advancement,
improvement of manufacturing
processes, and rapid reduction in fiber
cost, extending optical fiber to the user
has become the development trend of
access layer.
Recent years have seen explosive
growth of fiber-based Passive Optical
Networks (PON). With features like
fiber saving, passive devices, easy
maintenance and transparent network
protocols, PON systems have aroused
widespread interest from industry and
are playing an increasingly important
role in building FTTx networks at the
access layer. ZTE has developed a series
of PON and ODN products capable of
delivering diversified FTTx solutions
that can be applied to various scenarios
like fiber to the home (FTTH), fiber to
the building (FTTB), fiber to the curb
(FTTC), fiber to the office (FTTO) and
fiber to the village (FTTV). Its total
FTTx solution is illustrated in Figure 1.

■ Powerful support platform for
smooth evolution
ZTE FTTx solution supports not
only EPON and GPON but also the
smooth evolution to NG PON without
any alteration to the main boards,
power boards, or uplink boards. In
order to support NG PON technology
while allowing coexistence with
existing GPON/EPON users in the
same ODN network, it only requires the
insertion of XG PON, 10GEPON, or
WDM PON line cards into the GPON
or EPON rack without changing the
original GPON/EPON ONT. This can
protect operators’ initial investment.
■ Rich TDM uplink ports supporting
time and clock synchronization
ZTE FTTx solution offers a variety
of high density TDM uplink ports such
as E1/T1/STM-1/STM-4 to meet the
access demand of all TDM services—
including PBX and DDN private lines.
It also supports the IEEE 1588v2
Precision Time Protocol (PTP) and
provides FE/GE and 1PPS+TOD ports,
which can implement time and clock
synchronization for 2G/3G mobile
6 5

backhaul.
As illustrated in Figure 2, the OLT
connects to MSTP/MPLS transport
network and BSC/RNC through the
E1/STM-1/GE port. It obtains 1588v2
time synchronization data from the
IP network through the FE/GE port,
or clock synchronization data from
the GPS receiver or the 1588 master
through the 1PPS+TOD port. All time
and clock data are transmitted to the
ONU through the PON system. Then
the ONU transmits time and clock
synchronization data to the BTS/NodeB
through the 1PPS+TOD port or the FE
port. In this way, the clock and time
synchronization of the whole network
can be achieved.
With the widespread application of
IP-based base stations and the rapid
growth of IP-based 3G and even 4G
mobile networks, the key problem for
operators is the transfer of time and
clock synchronization data between
IP-based base stations and IP-based
networks. ZTE FTTx time and clock
solution is an ideal solution to the
problem.
In addition, ZTE FTTx provides
DiffServ QoS guarantee through
security controls like flexible VLAN
QinQ support, perfect QoS solution,
and port location information.
ZTE’s FTTx solution has been
commercially deployed around
the world. By June 2009, ZTE had
snatched a 19% market share in the
FTTx application segment, ranking first
place in the world according to a report
by consulting firm iDATA. Drawing
on its rich experience in broadband
access, ZTE is capable of delivering
customized FTTx solution, helping
operators build future-oriented green
broadband networks with the lowest
TCO.

ZTE’s ZXA10 C300
December 31, 2009
By Erik M. Keith, Principal Analyst for Broadband Infrastructure at Current Analysis
Current Perspective
ZTE’s ZXA10 C300 solution is
very threatening to competitors
in the global FTTP market. The
new ZXA10 C300 platform is one of
only a handful of FTTP OLT solutions
that supports both standards-based
GPON and EPON, not to mention
point-to-point active Ethernet (AE)
FTTP and 10G EPON. This gives ZTE
a solid competitive advantage in terms
of deployment flexibility vis-à-vis
rival vendor OLTs, most of which will
support only one or two of the various
FTTP connectivity options.
ZTE asserts that its xPON solutions
(specifically EPON and GPON) have
been widely deployed in operators
networks worldwide since 2004. These
deployments include FTTH, FTTC,
FTTO, FTTB, FTTB+LAN, and
FTTB+DSL configurations; customers
i n c l u d e C h i n a Te l e c o m , C h i n a
Netcom, China Mobile, Shanghai
Broadband, Telecom Malaysia, PCCW,
Telecom Italia, and other operators.
In terms of key metrics, ZTE’s
ZXA10 in the C300 configuration
supports 400/800Gbps and 20/40Gbps
of bandwidth per subscriber slot.
400Gbps of redundant throughput
places the C300 at the sharp end of
the FTTP OLT spectrum, with only a
small group of vendors able to assert
backplane/switching capacities that
are equal or higher; likewise, 20Gbps
of per-slot throughput is the current
high-tide mark for OLTs.

Third Eye
The ZXA10 C300 is one of a small handful of
FTTP OLT platforms supporting both GPON and EPON;
the fact that it also supports active Ethernet and 10G
EPON gives ZTE additional differentiation.
ZTE’s ZXA10 C300 platform,
which first debuted in Q4 2008 at
an Italian telecom trade show, has
been generally available since June
2009. However, for such a powerful
platform (again from the speeds/feeds
standpoint), ZTE has engaged in a
rather limited marketing campaign,
which can even be construed as a
“soft” launch, compared to other
vendors offering similar solutions.
Whether this is a function of ZTE’s
still-low-profile marketing strategy or
due to limited availability of the C300
(or both) remains an open question.

chassis.
■ The ZXA10 C300 also supports
two and four-port 10G EPON;
when deployed in the 14-port
or 16-port chassis, which with
a 1:32 split ratio (assuming the
current IEEE standard), this equals
896/1,792 and 2,048/4,096 ONUs/
ONTs/subscribers per chassis.
■ In terms of WAN uplinks, the
Z X A 1 0 C 3 0 0 s u p p o r t s t h e
following cards: 4×10GigE,
4/8/16×GigE, 1×STM-4/OC-12,
2×STM-1/OC-3, and 32×E1/T1
(balanced and unbalanced).
Deployment flexibility
■ The ZXA10 C300 is one of a small
handful of FTTP OLT platforms
supporting both GPON and EPON;
the fact that it also supports active
Ethernet and 10G EPON gives ZTE
additional differentiation, at least
from a data sheet perspective. For
reference, Enablence’s TRIDENT7
was one of the first OLTs to supports
both GPON and EPON, and ZTE
still needs a commercial, operator
deployment of the 10G EPON
solution for customer/market
validation.
■ In addition to the EPON/GPON/
AE/1 0G EPON capabilities of the
ZXA10 solution set, the fact that
ZTE’s customers have deployed
the platform in a broad array of
FTTx configurations—FTTH,
FTTC, FTTO, FTTB, FTTB+LAN,
a n d F T T B + D S L — h i g h l i g h t s
the deployment flexibility of the
ZXA10 series.
■ The ZXA10 solution set also
supports long-reach PON (i.e.,
up to 60-km/37-mile links from
t h e O LT t o t h e O N U / O N T ) ,
giving operators the ability to
deliver FTTP services within a
much larger serving area than the
standard 20km link. However,
ZTE is certainly not unique in this
respect, and there is a bandwidth
tradeoff with long-reach PON (e.g.,
a 20Mbps connection at 20km will
likely be 10Mbps at 40km).
ONT range
■ ZTE asserts support for a full
r a n g e o f O N T f o r m f a c t o r s
for both indoor and outdoor
deployments, but other than
offering FTTB+Ethernet and
FTTB+DSL systems with optical
WAN interfaces, it is not highly
differentiated from rival vendors in
this respect.

ZTE arranged for me to meet with the

Telstra Corp. Ltd.,
and view a live

ZTE says it invests up to 10% of
gross revenues in R&D each year and
experienced 40% growth between
Q208 and Q209. Along the way, it
secured the No.1 equipment provider
position in the Chinese marketplace, in
terms of incremental units shipped in
2009.
CSL selected ZTE as its strategic
partner and turnkey provider of a
recently implemented HSPA+ Software
Defined Radio (SDR) network to
address several specific challenges
including slow data rates and no
clear path to LTE. The transition
was further complicated by the fact
that CSL was operating a network
with a pair of technology standards
(GSM/WCDMA), and three different
spectrum bands (900/1800/2100MHz).
Keep in mind that CSL had over 2,000
cell sites in Hong Kong and more than
2.5 million existing customers. In
20 March 2010 ZTE TECHNOLOGIES

addition to handsets and the HSPA+
network, ZTE is providing CSL with
microwave Ethernet backhaul (70–100
megabits per second) and all-IP packet
core network equipment. In short, ZTE
provided a turnkey network in arguably
one of the most RF challenging markets
in the world.
ZTE has proven its ability to
secure major tenders in emerging
markets as well as developed markets
through innovation, customization and
an integrated product suite including
core networks, SDR access network
equipment capable of operating on all
technologies and handsets. The big
question for 2010 will be whether it
can secure a tier-one mobile operator
contract. Based upon the company’s
successes during the past 24 months, it
is hard to imagine a scenario where it
does not secure a seat at the LTE table
in the U.S. marketplace. Competition
will be fierce.
ZTE also continues to focus
heavily on the CDMA market, having
recently won a contract to build out
a CDMA2000 1x EV-DO Rev.B
network for Indonesia’s Smart Telecom
and continues to supply equipment
to CDMA-based carriers in North
America.
ZTE stats:
■ ZTE owns a complete wireless

Research Note
Realizing the Software Evolution
of Existing BOSS with
ZTE SEEM
By Zhan Zhang
Background
New market demands have
impacted telecom carriers
in multiple ways; they have
enhanced customer experience, reduced
OPEX & CAPEX, shortened the time
to market, created new business models,
and digested and applied cutting edge
technologies. Every telecom carrier must
have an evolvable Business and Operation
Support System (BOSS) to satisfy these
demands.
BOSS is primarily a complicated and
sophisticated software system, containing
multiple components according to
standardized specifications (e.g. eTOM
and NGOSS). All these components
cannot usually be implemented
simultaneously due to budget constraints
or manpower constraints. Since it takes
a long time to construct the whole BOSS
and it is impossible to foresee all changes
in the initial stage of BOSS construction,
each CIO/CTO faces the challenge of how
to evolve or replace these legacy systems
to support changing market requests. This
is a frustrating thing.
Owing to ROI constraints, the decision
to renovate a legacy BOSS component or
replace it with new one poses a dilemma.
However, regardless of which solution
is chosen, the following difficulties are
inevitable in the process of upgrading
BOSS.
■ Communication with multiple
software vendors
■ Integration with heterogeneous
architectures
■ Satisfying continuous market
demands
■ Expending the life-cycle of existing
BOSS components
Addressed Issues and Solution Space
The background of these issues has, so
far, been clearly understood. The purpose
of this article, however, is to find a
practical methodology by which a legacy
BOSS component can evolve to fit new
requests with minimal pain and cost. The
main topics discussed in this article are:
■ What is a suitable methodology to
realize BOSS component upgrading
■ How can this methodology be applied
to upgrade BOSS components in a
reasonably short time
■ What are the necessary tools to
support this methodology
According to our study, there are
two theoretical foundations in software
engineering that can be applied: software
maintenance and software evolution. Each
of these can support software upgrade,
but their purposes are slightly different.
The following section will briefly review
the two methodologies theoretically.
Literature Review
This section introduces the concepts
of software maintenance and evolution,
especially the latter, since our approach
adopts several methodologies of software
evolution.
Software maintenance
Software maintenance is a set of
activities which changes the system after
it has been delivered. They involve:
■ Corrective maintenance: repair of
software faults
■ Adaptive maintenance: modification
of software due to changes in the
operating environment (hardware,
supporting software)
■ Perfective maintenance: additions
to or modifications of system
functionality due to organizational or
business changes
■ Preventive maintenance: activities
which attempt to prevent unnecessary
changes in the future
Software maintenance is very
important in the lifecycle of software.
In fact, costs associated with software
maintenance often equal those of
software development. The main focus
of maintenance is the addition and
modification of functionality, whereas
fault repair and software adaptation

eceive much less attention, as shown in
Figure 1.
Fultrepair
Software adaptatior

Figure 1. Distribution of maintenance
efforts.
As time progresses, maintenance
becomes much more difficult due to:
■ Staff turnover and the discontinuation
of knowledge
■ Changes in staff skills as main-trend
technologies change
■ The age of original software and
the increased cost of maintaining its
structure
■ Contractual responsibilities on a
maintenance team, which may limit
the software’s capability and the
allocation of money for maintenance
tasks
Software evolution
Prof. Meir M. Lehman et al. have
identified a set of behaviors in the
evolution of proprietary software. These
behaviors (or observations) are known as
Lehman’s laws, and they include:
■ Continuing change: Programs used
in a real-world environment must
necessarily change or become
progressively less useful in that
environment.
■ Increasing complexity: As a program
evolves, its structure tends to become
more complex. Extra resources
must be devoted to preserving and
simplifying the structure.
■ Self regulation: Program evolution
is a self-regulating process. System
attributes such as size, time between
releases, and the number of reported
errors is almost invariable for each
system release.
■ Organizational stability: Over
a program’s lifetime, its rate of
development is approximately
constant and independent of the
resources devoted to system
development.
■ Conservation of familiarity:
Over the lifetime of a system, the
incremental change in each release is
approximately constant.
■ Continuing growth: The functionality
offered by systems must continually
increase to maintain user satisfaction.
■ Declining quality: The quality of
systems will appear to be declining
unless they are adapted to changes in
their operational environment.
■ Feedback system: Evolutionary
processes incorporate multi-agent,
multi-loop feedback systems and
must be treated as feedback systems
in order to achieve significant product
improvement.
According to research themes
identified by Bennett and Rajlich,
aspects of software evolution currently
being investigated include requirements,
architecture, data, runtime management,
service-orientation, and language.
Solutions being offered involve reverse
Figure 2. Foundation of SEEM: re-engineering and wrapping.
and re-engineering, incremental change
techniques, managerial issues, software
processes, and model evolution. There
emerge two prevalent views:
■ What and why: This line of
questioning focuses on software
evolution as a scientific discipline.
It studies the nature of software
evolution phenomena, and seeks to
understand the driving factors and
impacts.
■ How: This line of questioning
focuses on software evolution as an
engineering discipline. It studies the
more pragmatic aspects that aid the
software developer or project manager
in their day-to-day tasks.
Foundations of approach
The approach proposed here draws
on several methodologies of software
evolution (see Figure 2). The horseshoe
re-engineering model is very popular in
realizing software evolution. As shown
in Figure 2, a legacy software system
can be built into a high-level architecture
model, which can then be improved
to a restructured model. Finally a new
software system can be developed from
the restructured model. The agentbased
wrapping model is another way of
renovating a legacy software system.

Proposal
Our approach is called Software
Evolution Enhanced Methodology
(SEEM), and it addresses the BOSS
domain. It defines the basic practice,
process flow, and infrastructure, as shown
in Figure 3.
In order to achieve its goal, SEEM
defines a process as shown at the bottom
of Figure 3. This process comprises a
series of internal activities:
■ Stage A: This is the first stage of the
SEEM flow. It involves collecting and
extracting information from a legacy
BOSS component by observing
external standards, new technology,
and business requests.
■ Stage B: Upon collecting this
information, SEEM performs
an impact analysis according to
evaluation criteria—including priority,
cost/expense, and market trends.
■ Stage C: This stage is called
“Roadmap Generation”. It determines
a suitable approach, such as reengineering,
wrapping, or refactoring,
according to the previous analysis.
■ Stage D: This stage involves
rebuilding the meta-model of the
BOSS component. It primarily
impacts architecture, interface,
interaction, and data structure.
Therefore, the legacy BOSS
component can be encapsulated (e.g.
transformation, synchronization, and
replication) and upgraded.
As these internal activities are ongoing,
changes to the BOSS components are
ongoing as well. The relationships are
described in Figure 3. These changes can
be broken down into multiple phases, as
described below:
■ P r o b i n g : D a t a c o l l e c t i o n ,
configuration, meta-model extraction,
and log analysis is performed.
■ Implementation: Strategies such as
refactoring, wrapping, re-modeling,
replacement, and tailing, are employed
to realize implementation according
to detailed requests.
■ Simulation & Validation: All
implementation results are simulated
and validated before commercial
launch. Key activities in this stage
include preparing a test-case,
performing a dry-run, deploying
environment, and organizing a team.
■ Migration & Monitoring: All validated
results are migrated to the commercial
environment. Data, business logic,
interface, and interaction models will
be changed.
To support these activities and
processes, SEEM is built on a standard
infrastructure which includes:
■ A UML tool: Unified Model
Language (UML) is used to model
and describe the request, architecture,
and process flow.
■ CVS: Control Version System (CVS)
is used for version and release control.
■ A ZSmart framework: ZSmart is
a collection of BOSS components
provided by ZTE. It is organized as
multi-level architecture. The bottom
level is called ZSmart framework—
an open-structure framework used
to implement all non-business
requests (e.g. logging, reporting, and
messaging).
■ A visualization tool: Since BOSS is
too large to image, the visualization
tool can help designers, developers,
and testers easily identify changes and
issues.
■ A refactoring tool: This is always
included as a popular development
tool (e.g. Eclipse and NetBeans).
■ A monitoring tool: This aids in
quickly understanding changes which
are occurring in the whole process.
This approach features end-to-end
capability, multiple tactics, wrapper
support, extreme programming tolerance,
a staged process, UML standardization,
simulation embedding, separate internal/
external activities, legacy technology
compatibility, eTOM addressed, unified
processes, and it is meta-model driven.
Figure 3. SEEM practice, infrastructure and flow.
Summary
Using SEEM based software evolution,
software maintenance, and a Zsmart
framework, a legacy BOSS component
can be upgraded with less cost and effort.
The main advantage of SEEM is that
it balances maintenance and evolution,
extends the life-cycle of legacy BOSS
component, and supports a heterogeneous
environment.

Solution
UEMS
Boosts Network
OAM Efficiency
By Xue Qinghua, Zhou Yongkang
Telecom operators are continuing
to feel the pressure as end
users demand more flexibility
and lower prices for telecom services.
Fierce competition gives impetus to
technological innovation, and while
flat network structure has been the
trend, it is moving forward quickly.
Consequently, an increasing number
of telecom operators are evolving to
become full-service providers that can
operate multiple types of networks.
These include access networks, core
networks (CN), transmission networks,
data networks and service networks,
with a large number of network devices.
Changing network structure,
however, poses a big challenge for
operators. Handling new complex
networks with legacy management
architecture is costly. Therefore, it has
become necessary to solve new network
OAM problems while keeping costs to a
minimum. Proactive trials are underway
in the industry, and ZTE’s Unified
Element Management System (UEMS)
has been accepted by most operators as
an effective answer to these problems.
ZTE has rolled out a unified network
management solution that can help
operators manage multiple private
networks and improve their network
OAM efficiency.

The core of UEMS is unification—
transforming network management from

management. This is achieved through
the convergence of multiple EMSs into
one. The UEMS network topology is
shown in Figure 1.

has had its own EMS. Besides
higher power consumption, multiple
EMSs require larger space and more
maintenance teams. However, UEMS
demands only one maintenance team to
implement centralized management of
all network devices in the system. This
reduces maintenance staff workload and
increases network OAM efficiency.
UEMS incorporates an efficient
rights-based management system,
assigning permissions to users
according to their roles and domains.
Users are concerned only with their
assigned NEs. They can only see their
authorized NEs at the user interface,
and their maintenance habits can be
recorded. If any user has authority to
manage all NEs, he can see all these
NEs at the user interface. Rights-based
management is illustrated in Figure 2.
In Figure 2, different users share one
UEMS server with different authority
rights and permissions according to
their user experience.
Flexible Networking
Considering variance in network size,
UEMS provides diverse networking
modes—such as layered or centered
networking topologies—according to
operators’ administrative organizations.
A common scenario is a small but
complicated network containing a small
number of different NEs. With legacy
management architecture, operators
need to install many EMSs for
management of different NEs, which
raises high OPEX. However, with
UEMS, the different NEs are managed
through related management modules
that are deployed as a single server.
This leads to low-cost co-management.
Another scenario is a large-sized
and complicated network containing a
large number of multiple types of NEs.
To implement load sharing, UEMS
can deploy different NE management
modules in different servers. However,
the user need manage all NEs through
one client only.
Flexible networking solutions not
only satisfy operators’ customization
demands, but also cut their OPEX with
reasonable OAM flows.
Uniform Portal
UEMS provides all the common
network management functions:
topology management, security
management, log management,
performance management and fault
management. The functional modules
have a perfectly uniform operational
interface. So whatever types of NEs
are being operated, their user interfaces
are homogeneous. For the special
functions of each private network, its
user interfaces retain the same style; the
uniform GUI style helps users quickly
learn the UEMS operations, acquire
different NE management skills,
and develop strong network OAM
capabilities.
In addition to uniform GUI style,
UEMS employs a uniform portal that
can customize functions to the user’s
preference. UEMS users may operate
one or more types of NEs, and can
customize system functions or place job
related content together according to
their personal habits or job requirements.
In this way, users complete their
maintenance work more effectively.
Figure 3 is a customized view of the
user interface.
