System and method for supporting robust header compression in wireless communication system

摘要

A system and method support robust header compression (ROHC) for a mobile station (MS) handover in a wireless communication system. If a mobile station (MS) accesses a base station (BS) controlled by the ASN-GW through a handover, ROHC parameter information is received from a previous ASN-GW controlling a previous BS accessed by the MS before the handover. An ROHC parameter for ROHC-based communication with the MS is determined on the basis of the ROHC parameter information received from the previous ASN-GW. The determined ROHC parameter is transmitted to the MS by using a path modification request message for an ROHC service flow.
