Reasons for the question
The growth of demand for IP-based network services and for
Intelligent Network services reflects the synergistic
opportunity for new revenue streams provided by the combination
of these technologies and architectures. Service providers, both
traditional and new, recognize the opportunity for strategic
business advantages enabled by the use of technology that allows
service differentiation while using standard functional elements
to realize those services. Finally, service providers anticipate
the ability to reduce the complexity of service development and
provision.
The ITU has published recommendations concerning the
Intelligent Network (IN) conceptual model, the basic call state
model, and numerous IN-based network capabilities. The IETF has
published numerous IETF standards concerning the definition and
use of the Internet Protocol (IP), in particular, those
emanating from the PINT WG involving interaction with
traditional telephony services via the IN. During the 1997-2000
Study Period, framework documents have been prepared that
identify IN support for PINT services in H.323-based and
SIP-based networks. Furthermore, PINT support is available with
the current IN Capability Sets.
In many areas of the globe, public services are still relying
upon the existence of an ITU-T recommendation before deployment
of such services may be made. Therefore, it is necessary to
create such recommendations to provide the framework for the
interaction of IN-based services and IP-based network services.
Question
What new recommendations and additions to existing
recommendations are required to specify signalling requirements
for new, value added, Internet based and Intelligent Network
(IN) based services?
Task objectives
1) Establish requirements in ITU-T Recommendations Q.1241
and Q.1244 to accommodate new framework information to support
new, value added, Internet based and Intelligent Network (IN)
based services.
Expected completion: 4Q2001.
Relationships
The tasks of this question are related to the specification
of U-plane and C-plane protocols that support or use IN
principles with IP-based networks. The activities leading to
successful completion of these tasks require interactions with
IETF working groups, e.g. PINT and SPIRITS. Specification in
this area is related also to ITU-T efforts with ITU-T H-series
Recommendations, e.g. H.323 and H.248. |
