CT5 develops Application Programming Interfaces (APIs) for the Open Service Access (OSA). The UMTS network provides these interfaces to facilitate service implementations. CT5 is responsible for the following specifications:
- Stage 2 for the UMTS OSA Architecture (TS 23.198);
- Stage 3 for the interfaces specific to the UMTS OSA (TS 29.198-series);
- Definition of the interface classes, methods and detailed behaviour of those classes (TS 29.198-series);
- IDL, WSDL, Java specifications of the UMTS OSA-specific interfaces (TS 29.198-series);
- Functional mapping of OSA interfaces to UMTS network protocols (TR 29.998-series);
- OSA interfaces at high level of abstractions (also known as Parlay X Web services 29.199-series).
The work of CT5 is based on the Service Requirements set by SA1 and on the 3GPP Architecture defined by SA2.
Dependencies with other groups;
- Inside 3GPP: direct relationship with SA1/SA2;
- Joint meetings with ETSI TISPAN, the Parlay Consortium and 3GPP2 with the aim to work on a common technical basis for the standards, in the areas where the scopes overlap;
- External organizations with which CT5 does not liaise directly, but which carry out similar kind of work: ITU-T (liaison via ETSI TISPAN).
- Providing alignment with other Web Services specifications, CT5 utilizes specifications and profiles published by W3C, WS Interoperability Organization (WS-I) and OASIS.
