| Zusammenfassung: | PURPOSE: A system and a method for supporting a robust header compression in a wireless communication system are provided to support ROHC(Robust Header Compression) without exchanging context information during handover between ASN-GWs. CONSTITUTION: A second ASN-GW(Access Service Network-GateWay)(120) receives ROHC variable information from a first ASN-GW(110). The second ASN-GW transmits a ROHC variable to a terminal by using a dynamic service change request message about a ROHC service flow. The terminal receives the dynamic service change request message. The terminal checks a ROHC variable included in the dynamic service change request message. The terminal reset a context information for the ROHC. |
