Universal Mobile Telecommunications System (UMTS); Open Service Access (OSA) Application Programming Interface (API); Part 4: Call control; Subpart 1: Common call control data definitions (3GPP TS 29.198-04-1 version 5.3.0 Release 5)
The present document is Part 4@ Sub-part 1 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 23.127 [3]. The requirements for OSA are contained in 3GPP TS 22.127 [2]. The present document specifies the common definitions used by the Call Control Service Capability Features (SCF). This specification has been defined jointly between 3GPP TSG CN WG5@ ETSI SPAN 12 and the Parlay Consortium@ in co-operation with a number of JAIN? Community member companies.
