US 2008/0076441 A1 · METHOD AND SYSTEM FOR PROVIDING QUALITY OF SERVICE ASSURANCE IN WIRELESS COMMUNICATION SYSTEM

Abstract

The present invention relates to a method and a system for providing a quality of service assurance in a wireless communication. The method primarily includes: defining lossless relocation indication information in a WiMax system, transferring the lossless relocation indication information between entities of the WiMax, and providing a quality of service assurance to a corresponding service flow according to the transferred lossless relocation indication information. The present invention also defines end to end MSS-ASN-CSN QoS parameters for WiMax, so that the WiMax may selectively carry out lossless relocation, thereby providing more appropriate QoS parameters for the WiMax system and improving the performance of the wireless communication system. The present invention also defines end to end MSS-ASN-CSN QoS negotiation procedures for WiMax, so that the QoS over the whole end to end MSS-ASN-CSN bearer may be assured for the WiMax, thereby providing differentiated services for WiMax users.
