METHOD OF CREATING AND DELETING A SERVICE FLOW FOR ROBUST HEADER-COMPRESSSION, AND WIRELESS COMMUNICATION SYSTEM FOR SUPPORTING THE SAME

摘要

A method of creating and deleting a service flow for robust header compression, and a wireless communication system for supporting the same are provided to perform negotiations between ROHC entities for ROHC parameter by transmitting message using service flow information including ROHC parameter. When an ASN- GW(Access Service Network Gateway)(110) obtains a ROHC applied subscriber profile, the ASN-GW gets a first parameter from ROHC entities, and then transmits a first message including the first parameter to a base station(108). The base station performs the DSA(Dynamic Service Addition) procedure with a terminal(120) related to the subscriber profile using a second message including the first ROHC parameter. When the base station receives a response message for the second message including the second ROHC parameter for the ROHC negotiation from the terminal, the base station transmits a response message for the first message including the second ROHC parameter to ASN-GW.
