OSA API Joint Working Group

The OSA specifications define a set of APIs that enables operator and 3rd party applications to make use of network functionality through a set of open, standardized interfaces.

All About OSA - a presentation on OSA

Working Methods

The Joint Working Group derives its specifications from a UML model of the OSA API.  Using the latest document and code generation techniques, the detailed technical description documents, the IDL code WSDL code and Java API are all produced from a single source UML model.  This ensures alignment between all versions, all formats of the API.

ETSI publishes the master specifications of the APIs.  The Parlay Group point to this published ETSI specification instead of re-publishing it.  
3GPP maintain their own specifications, which have the same structure as the ETSI specification.  Each part of the 3GPP specification is a subset or a copy of the ETSI specification.

Relationship between ETSI, Parlay and 3GPP OSA Specifications

Joint meetings are held between the ETSI TISPAN OSA Project, 3GPP CT5, Parlay and JAIN.  The invitation to the next meeting is available at:

All meeting documents since May 2005 are numbered as 3GPP CT5 documents and can be viewed at: http://www.3gpp.org/ftp/tsg_ct/WG5_osa_ex-CN5/

Previous meeting documents are numbered as 3GPP CN5 documents and can be viewed at: http://www.3gpp.org/ftp/TSG_CN/WG5_osa/.
