29.3643GPPIP Multimedia Subsystem (IMS) Application Server (AS) service data descriptions for AS interoperabilityRelease 17TS

Application Servers can store their service data on the HSS through the Sh interface as transparent data, meaning that the HSS may not be aware of the structure and the semantics of this data, only the Application Server has this knowledge. Standardizing the data formats would facilitate interoperation among Application Servers supplied by the same, or different, vendors. These Application Server vendors may be primary and secondary suppliers of the same service provider within a service provider’s IMS network. This is especially true for the Multimedia Telephony supplementary services that can achieve a wide deployment and are here addressed by this specification.

IMS CAMEL subscription data may be transferred to the IM-SSF AS using Sh interface.
