scope:

The present document is 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 23.127 [3]. The requirements for OSA are contained in 3GPP TS 22.127 [2].

The present document specifies the Common Data definitions of the OSA. The Common Data definitions contain datatypes that are common across the rest of the OSA API. All aspects of the Common Data are defined here, these being:

- Data definitions

- IDL Description of the interfaces

This specification has been defined jointly between 3GPP TSG CN WG5, ETSI TISPAN and The Parlay Group, in cooperation with a number of JAIN™ Community member companies.
