29.198-04-23GPPOpen Service Access (OSA) Application Programming Interface (API)Part 4: Call controlRelease 9Subpart 2: Generic call control Service Capability Feature (SCF)TS

The present document is Part 4, Sub-part 2 of the Stage 3 specification for an Application Programming Interface (API) for Open Service Access (OSA).

The OSA specifications define an architecture that enables application developers to make use of network functionality through an open standardised interface, i.e. the OSA APIs. The concepts and the functional architecture for the OSA are contained in 3GPP TS 23.198 [3]. The requirements for OSA are contained in 3GPP TS 22.127 [2].

The present document specifies the Generic Call Control Service Capability Feature (SCF) aspects of the interface. All aspects of the Generic Call Control SCF are defined here, these being:

  • Sequence Diagrams
  • Class Diagrams
  • Interface specification plus detailed method descriptions
  • State Transition diagrams
  • Data definitions
  • IDL Description of the interfaces
  • WSDL Description of the interfaces
  • Reference to the Java™ API description of the interfaces

The process by which this task is accomplished is through the use of object modelling techniques described by the Unified Modelling Language (UML).

This specification has been defined jointly between 3GPP TSG CT WG5, ETSI TISPAN and the Parlay Group, in co-operation with a number of JAIN™ Community member companies.
