2 Alcatel-Lucent 5750 Subscriber Services Controller
The Alcatel-Lucent 5750 Subscriber Services Controller (SSC) is a flexible, modular and
prein tegrated subscriber- and policy-management solution that controls Alcatel-Lucent’s
Triple Play Service Delivery Architecture (TPSDA), enabling innovative IMS (IP multimedia
subsystem) and non-IMS services to be dynamically created on an IP infrastructure
capable of delivering different quality of service (QoS) levels. 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
employ ing 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.
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 networkdesign 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-the-
Challenges and Opportunities of Triple-Play Service Delivery
Alcatel-Lucent 5750 Subscriber Services Controller 4
user (FTTU) access technologies,
a shift from ATM to Ethernet-based
service aggregation, IP/MPLS serv ice routing, IP multi cast, and ondemand 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 nondisruptive 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 policycontrol 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 tripleplay service delivery and unlock its
full revenue potential.
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.
