manual abstract
The Alcatel-Lucent 5750 SSC is instru mental in cost-effectively delivering next-generation IP-based services such as broadcast IP television (IPTV), video on demand (VoD), voice over IP (VoIP), enhanced Internet services (EIS) and emerging IMS services to a mass market, while enabling a personalized and seamless user experience across all bundled services. On-demand subscriber self-service portals and network-policy auto generation allow service providers to minimize operational costs by employing a flexible, “zero-touch” service-delivery model that caters to indi vidual subscriber preferences and evolving service needs. The Alcatel-Lucent 5750 SSC reduces operational transformation risks and the costs of introducing new network architecture and services. Its modularity and flexibility enable deployment in phases, allowing service providers to satisfy initial service-deployment requirements while investing in a future-safe plat form that can be leveraged to scale VoD, migrate toward IMS, support emergency systems for IP telephony, introduce mandatory law systems for Internet service, etc. The Alcatel-Lucent 5750 SSC also provides a graceful subscriber migra tion from best-effort services delivered using the legacy broadband remote access server (BRAS) network to EIS on the Alcatel-Lucent TPSDA. The Alcatel-Lucent 5750 SSC removes the need to duplicate back-office sys tems by centralizing subscriber and policy management for both TPSDA and the legacy BRAS on one plat form. Modularity and proxy functions also minimize legacy-network config uration changes and enable a smooth transition to centralized operations. Alcatel-Lucent 5750 Subscriber Services Controller 3 Challenges and Opportunities of Triple-Play Service Delivery Triple-play service delivery — blend ing voice, video and data services in an integrated service bundle — is a generational leap that carries with it certain challenges. • Today’s Internet service-delivery networks are optimized for flat-rate, best-effort commodity services. With the advent of triple play, high-revenue services such as inter active multimedia applications, VoIP, VoD and broadcast TV (BTV) become the dominant network- design drivers. These services place unprecedented scalability, reliability, flexibility and QoS requirements on the IP-network infrastructure. • New user devices such as residen tial gateways (RGs), IPTV set-top boxes, IP phones and gaming con soles are being intro duced in the digital home network and must be managed and con trolled. Fiber-tothe- node (FTTN) and fiber-to-theuser (FTTU) access technologies, a shift from ATM to Ethernet-based service aggregation, IP/MPLS serv ice routing, IP multi cast, and on- demand session-admission con trol are driving oper ational support requirements for which legacy systems were not designed. • While transforming to a converged, multiservice IP infrastructure, ser vice providers need to leverage and migrate strategic assets from the installed base of TDM voice and high-speed Internet (HSI) services to effectively up-sell existing sub scribers to a triple-play offering. This migration needs to be non- disruptive for the service provider and transparent to subscribers by allowing legacy service features to be seamlessly ported to the next-generation network (NGN) infra struc ture while minimizing operational impacts and costs. Beyond a profound network transfor mation, a centralized and reliable subscriber-management and policy- control infrastructure is required to enable millions of triple-play sub scribers and end-user devices to securely access and use network-based applications, services and content with assured quality of experience. The Alcatel-Lucent 5750 SSC is purpose-built to address these needs. The system enables service providers to be optimally positioned to success fully conduct network and service transformation to converged triple- play service delivery and unlock its full revenue potential. 4 Alcatel-Lucent 5750 Subscriber Services Controller A Whole New World of Services Alcatel-Lucent 5750 Subscriber Services Controller 5 The Alcatel-Lucent 5750 SSC allows service providers to increase the average revenue per user (ARPU) with the rapid creation and deployment of innovative triple-play services, enabling end users to package these services in personalized bundles. The Alcatel-Lucent 5750 SSC facilitates the introduction of new services (e.g., IPTV and VoD) and the evolution of traditional HSI services to EIS with support of dynamic bandwidth management and per-application QoS control. This allows service providers to enhance their value proposition by delivering a superior user experience for Internet video, gaming and multi media applications. The migration of legacy voice services to NGN and the introduction of IMSbased services are other strategic areas of innovation for which the Alcatel-Lucent 5750 SSC provides an evolution path for key control elements.
