Centralized Management
of Subscribers, Services
and Resource Policies
The Alcatel-Lucent 5750 SSC pro- vides a highly scalable and flexible policy-management framework that enables centralized and dynamic control over subscribers, services and network devices. The platform manages an integrated repository of subscriber account information and user credentials, user device profiles, service profiles and network resource- policy definitions. This information is externally accessible through open interfaces to allow integration with external subscriber data-management systems, such as IMS home subscriber service (HSS), and the service-control functions of application middleware (e.g., IMS application servers or IPTV middleware).
The Alcatel-Lucent 5750 SSC base product contains a broadband policy server that acts as a centralized policy- decision and orchestration point for the end-to-end access, aggregation and IP transport network, evaluating on-demand subscriber requests for access to network-based services and content.
The dynamic assignment of IP addresses to user devices is controlled with predefined static or dynamic
address pools that are managed using DHCP or RADIUS (combined with the DHCP or RADIUS server con- troller module or external servers).
These same network-access protocols or element-management system (EMS) plug-ins for multitechnology and multi- vendor network integration can be used to coordinate the real-time deployment of service-control policies and enable dynamic, on-demand policy modification.
Subscribers may trigger these modifications (e.g., dynamic service selection or upgrade) using a self- service web portal based on:
•Service-metering policy events (usage metering and triggering package)
•Application or network events (e.g., VoD session request, DPI virus detection alert)
•Timer expiration (e.g., end of service trial period)
With service components, subscribers can mix and match video, voice and Internet service packages and create personalized triple-play service bun- dles. These capabilities give service providers many options for simply and cost-effectively creating differentiated, and user-centric services in a simple and cost-effective way.
