Method of resuming header decompression in a multimedia broadcast/multicast service system

摘要

A method of resuming header decompression in a UE after the UE moves from one cell to another sharing the same header decompressor and header decompression context during an MBMS service in an MBMS system is provided. After moving from the old cell to the new cell, the UE suspends header decompression until receiving an IR-DYN packet from the new cell. Upon receipt of the IR-DYN packet, the UE updates the dynamic part of the header decompression context using the IR-DYN packet and resumes the header decompression using the updated header decompression context in the new cell.
