Study on IMS Application Server (AS) service data descriptions for AS interoperability
The present document studies requirements for application server service data definition. It also studies the transfer of the defined service data between an application server and the HSS. Further, it exposes a service data definition for a telephony application server for services as defined in 3GPP TS 22.173 [3]. Finally it provides recommendations for how the framework can be reused and extended for future IMS service definitions.
