This TS specifies network requirements in terms of service-related capabilities for a TISPAN NGN incorporating an IMS. This TS places requirements for TISPAN NGN Release 1 subsystems.
This TS provides generic requirements for services and interoperability in a TISPAN NGN incorporating an IMS in terms of the capabilities for a network or networks.
Requirements on service-related subsystems provide sufficient detail for architecture, networking requirements and protocols to be specified.
Specific service requirements may be contained in other documents, as identified in this TS, and by other documents referencing this TS.
This TS does not define services, only capabilities and requirements. This TS does not place requirements on terminals or other customer-owned equipment. This TS specifies the service-related requirements on an IMS that are used to determine the network architecture, requirements and control protocols for a network interface to a customer environment.
