TECHNIQUES FOR COMPRESSING SESSION INITIATION MESSAGES USING TEMPLATES FOR EVOLVED DATA COMPRESSION SCHEME (EDCS)

摘要

Session initiation messages may be compressed using templates for evolved data compression scheme (eDCS). One or more session initiation messages may be exchanged between various network entities, such as UEs and base stations, for purposes such as registration, call setup, and call modification, for example. Session initiation messages may include header fields which identify the caller and characteristics of the device receiving the call, and may also contain payload, which describes the audio/video codec characteristics. Many of these contents may be repeated across all user devices of the same vendor attached to the same operator and may be compressed using templates to enhance system efficiency. These templates may be known at the transmitter and receiver, and reduce the data that has to be carried over air.
