HEADER COMPRESSION ENHANCEMENT FOR BROADCAST/MULTICAST SERVICES

摘要

PROBLEM TO BE SOLVED: To provide methods and apparatus for compression of headers in broadcasting BCMCS services in a wireless communication system.SOLUTION: Techniques used in BCMCS systems without feedback include sending static context information during BCMCS service initialization for use in a decompressor in a mobile station. Techniques used in BCMCS systems with feedback include receiving feedback from distributed mobile station decompressors and adjusting a broadcasting compressor in response to the feedback. Techniques that reduce the number of operating states in both the compressor and the decompressor are described. Techniques to classify flows so that a reduced number of contexts are used to compress/decompress session packet headers in a push-to-talk service are described.
