Telecommunications services based on the Internet Protocol are
replacing today's Public Switched Telephone Network (PSTN) at an
increasing rate. These services include Voice-over-IP services ordered
by subscribers in place of their existing landlines as well as
fixed/mobile convergence services employing technologies such as the IP
Multimedia Subsystem. Ultimately, too, service providers will begin to
substitute VoIP for conventional PSTN service as a cost-reducing
technology change-out transparent to the subscriber. Service providers
participating in this network transformation run the gamut from
competitive VoIP providers to wireless carriers, cable Multiple System
Operators, and incumbent local exchange carriers, large and small.
Some providers see the roll-out of IP-based services as an opportunity
to renew their OSS/BSS software stacks, deploying new systems entirely
separate from their legacy applications supporting today's PSTN. Yet,
for the foreseeable future, IP- and PSTN-based telecommunications
services-and the OSS/BSS infrastructures supporting them-will need to
exist in parallel. Providers must be able to take orders for, provision,
administer, and bill for services in both the IP and PSTN service
domains with equal ease, and without distinctions obvious to the
subscriber. The legacy applications will be around for some time to
come.
Since a large fraction of calls originating within one service domain
will terminate in the other, subscriber data must be maintained in a
consistent manner across the two domains. This White Paper introduces
Unified Subscriber Data Administration as a means of reducing the cost
and complexity of achieving this goal.
