IP Multimedia Subsystem (IMS) Application Server (AS) service data descriptions for AS interoperability
This specification standardizes
- the structure and the coding of the service data that are transported over the Sh interface between an Application Server supporting Multimedia Telephony supplementary services as defined in 3GPPP TS 22.173 [1] and the HSS. Two optional formats are specified. One is based on a binary coding of the service data and supports the subset of MMTEL services corresponding to PSTN/ISDN and CS supplementary services. The other uses an XML format and supports the full set of MMTEL Services.
- the structure and the coding of a set of generic IMS user group data over the Sh interface.
- the structure and the coding of the service data (ODB Information for IMS Oriented Services) that are transported over the Sh interface between an Application Server supporting services that are subject to IMS-ODB as defined in 3GPP TS 22.041[25] and the HSS.
- the structure and the coding of the IMS CAMEL subscription data transported using Sh interface.
