INTRODUCTION

This document is intended to define the OSA API Stage 3 interface definitions and it provides the complete OSA specifications for cdma2000^®1-based systems. This document is an extension of OSA API, per latest 3GPP TS 29.198 series specifications capabilities to enable operation in cdma2000^® systems environment as part of the TIA/EIA/IS-2000 family of standards. They are in alignment with 3GPP2 Stage 1 requirements and Stage 2 architecture defined in [17], [18] and [19]. These requirements are expressed as additions to and/or exclusions from the Release 5 specification of the 3GPP TS 29.198 series. The information given here is to be used by developers in 3GPP2 cdma2000^® network architecture to interpret the 3GPP OSA Specifications.

The OSA specifications define an architecture that enables application developers to make use of network functionality through an open standardized interface, i.e. the OSA APIs. These APIs are applicable to the 3GPP2 network architecture described in [17], [18] and [19].

The 3GPP TS 29.198 series specifications are included as a reference. It is intended that all upgrades to the TS 29.198 series Release 5 specification will also apply to this document.
