The present document is the first part of the 3GPP Specification defining the Application Programming Interface (API) for Open Service Access (OSA)@ and provides an overview of the content and structure of the various parts of this specification@ and of the relation to other standards documents . The OSA-specifications define an architecture that enables service 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]. This specification has been defined jointly between ETSI SPAN12@ 3GPP TSG CN WG5 and The Parlay Group (http://www.parlay.org)@ in co-operation with a number of JAIN?
