Subscriber and
Service Usage Accounting
The Alcatel-Lucent 5750 SSC inte- grates accounting capabilities for service usage. The system contains an accounting module that correlates and aggregates accounting information from various sources, such as per- service subscriber statistics from the Alcatel-Lucent 5620 Service Aware Manager (SAM). Service providers can therefore offer usage-based HSI service options. An optional format- ting and reporting back end supports flexible data-formatting options to enable the export of revenue data to external billing systems.
Lawful Intercept
Many countries mandate that service providers provide a secure interface that allows law enforcement agencies to intercept and monitor the Internet activities of subscribers suspected of criminal activities. A new module pro- vides a secure access interface, allow- ing service providers to leverage the Alcatel-Lucent 5750 SSC’s subscriber IP-address and network-location knowledge for lawful intercept sys- tems. The Alcatel-Lucent 5750 SSC Lawful Intercept Notification Server is preintegrated with the Alcatel- Lucent 1357 Unified Interception Suite, enabling ETSI compliance with government regulations.
ETSI TISPAN/IMS Support
IMS services present a strategic oppor- tunity for the migration of legacy PSTN voice subscribers, applications and infrastructure to an NGN infra- structure. Revitalizing and lowering the cost base of the voice-services infrastructure, IMS also enables serv- ice providers to tap new revenues with the introduction of a new generation of wireline or converged wireline/ wireless multimedia communica- tion services.
The Alcatel-Lucent 5750 SSC pro- vides two key components defined in the ETSI TISPAN architecture standards, offering an easy expansion path into the world of IMS, NGN and fixed-mobile convergence, as shown in Figure 2.
