Method for acquiring header compression context in user equipment for receiving packet data service

摘要

Disclosed is a method for acquiring a Header Compression (HC) context information in User Equipment (UE) to receive a packet data service from a mobile communication system. In the method, the UE receives packet data including a compressed header from a Radio Network Controller (RNC), and determines whether to request retransmission of all or part of the header compression context, based on the received packet data, and transmits the determined retransmission request to the RNC. The RNC retransmits all or part of the header compression context to the UE in response to the determined retransmission request.
