4.2.1.5 AAAC Attendant<br />
The AAAC attendant acts as AAAC client and is responsible for communication with AAAC server on<br />
behalf of the MT. This includes all security specific functionalities like key handling and network access<br />
procedures, i.e., it deals with registration and setup.<br />
This module deals further with a metering module. For that purpose it has an interface with the Metering<br />
module.<br />
4.2.1.6 Metering<br />
It deals with metering issues. It will be controlled by the AAAC attendant which will decide when start or<br />
finish metering a particular user session. Metering is based on the output of the IETF Real Time Flow<br />
Measurement working group with project specific enhancements.<br />
4.2.1.7 QoS Manager<br />
The QoS manager is responsible for QoS activities in the AR. It includes a Data Base with the DSCP<br />
table. The Policy Enforcement Point PEP is responsible for policing issues. The policy information is sent<br />
to the PEP by the QoS broker and the PEP stores it in the DSCP table. The QoS attendant receives QoS<br />
context transfer initiation order from the fast handover module and contacts the PEP so that the QoS<br />
infrastructure performs the QoS context transfer. Also the QoS attendant tells the FHO module of the<br />
availability or not of QoS resources in the nAR during the FHO process.<br />
4.2.1.8 Logger<br />
The Logger consists of two parts:<br />
• Integrated Logger which is integrated into AAAC Client and QoS Manager.<br />
• Local Log Management<br />
The AAAC Client’s Integrated Logger is responsible for generating Availability Event Logs and User<br />
Registration Event Logs, while the QoS Manager’s Integrated Logger is responsible for generating<br />
Availability Event Logs and Service Authorization Event Logs.<br />
