Alcatel-Lucent 5750 Subscriber Services Controller 13
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 infor mation
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 sus pected of
criminal activities. A new module pro -
vides a secure access inter face, allow -
ing service providers to lever age the
Alcatel-Lucent 5750 SSC’s subscriber
IP-address and network-location
knowl edge for lawful inter cept 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
infra structure, IMS also enables serv -
ice providers to tap new revenues with
the introduction of a new gener ation
of wireline or converged wireline/
wireless multimedia communi ca -
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.
