The Alcatel-Lucent 5750 SSC provides centralized management control and a data repository for:
•Subscriber administration — Creation and management of subscriber accounts, user profiles and device profiles
•Service administration — Creation of service profiles and triple-play services bundles
•Network-policy administration — Administration and configuration of per-subscriber and per-service resource policies in the end-to-end network
The flexible policy-management framework of the Alcatel-Lucent 5750 SSC uses this information for three key policy decision functions:
•Network access control — Authentication, authorization and accounting (AAA) for eligible subscribers and user devices to provide access to network-based services, applications and content, with the support of 802.1x EAP, RADIUS and DHCP. The Alcatel-
Lucent 5750 SSC provides full flexibility to attach user devices using a range of wireline and wireless-access network technolo- gies, with support for IP address assignment and management (IPAM) and the setting of appropri- ate security and QoS policies in the network. The Alcatel-Lucent 5750 SSC supports the ETSI TISPAN network attachment subsystem (NASS) specifications, providing a unified network access-control solution for both IMS and non- IMS service environments.
•Dynamic service control — Dynamic application of network policies, based on various triggers such as service or change requests from customer self-service portals, network events, timer events or operations support systems (OSS) (e.g., customer care ad billing). This control allows service providers to support dynamic service or band- width upgrades, offer try-and-buy service specials, redirect subscribers to a captive portal in case of non- payment or virus infection, etc.
•Service admission control — Assurance that sufficient resources are available in the network to ensure proper throughput guaran- tees (QoS) for the duration of the session. While resources for always- on services such as basic HSI access can be statically provisioned in the network, resource allocation for session-based services such as VoD is done dynamically for each request. The Alcatel-Lucent 5750 SSC also enables IMS-based services by supporting the ETSI TISPAN access resource and admis- sion control function (A-RACF).
Through its many open interfaces, the Alcatel-Lucent 5750 SSC coordi- nates and integrates information and control flows among the subscribers and user devices, OSS, application- control infrastructure, and end-to-end network to streamline operational processes associated with service delivery in real time.
