Session Initiation Protocol Message Payload Compression

摘要

A method, user terminal, and Session Initiation Protocol (SIP) Application Server for transporting SIP messages across an IP Multimedia network between the user terminal and the SIP Application Server. The sending side compresses message payloads within the application layer and the receiving side decompresses them at the application layer. The compressed message payloads are passed between the application layer and a SIP User Agent via an appropriate Application Programming Interface (API).
