Embodiment Construction

[0057]The core of the present invention is to define corresponding QoS parameters at the characteristic selection of WiMax system, and can carry out end-to-end QoS negotiation in WiMax system according to corresponding QoS parameters, namely the present invention proposes the parameters and the negotiation flow for the QoS of WiMax , wherein the defined QoS parameters also include some parameters that have not been used in the existing wireless network. The realization of the present invention enables end-to-end QoS guarantee to be realized in the WiMax system as well.

[0058] The present invention can also be applied in other wireless communication systems, such as WCDMA (Wideband Code Division Multiple Access) system, CDMA (Code Division Multiple Access) system, CDMA-2000 system, and D-SCDMA (Time Division Synchronous Code Division Multiple Access) system middle.

[0059] The parameters proposed by the present invention can be used for end-to-end negotiation of ASN GW, BS,...

Abstract

The implementation method of ensuring quality of service (QoS) in wireless communication system includes steps: first, in WiMax etc. wireless communication system, defining QoS parameters of lossless transfer indication; then, carrying out negotiation of QoS parameters including parameter of lossless transfer indication between entities in WiMax system; based on negotiated QoS parameters, the method provides QoS guaranty for corresponding traffic flow. Defining QoS parameters of MSS-ASN-CSN from end to end in WiMax system, the method makes WiMax possible to do lossless transfer selectively so as to raise performance of wireless communication system. The invention also discloses flow for negotiating QoS parameters of MSS-ASN-CSN from end to end in WiMax so as to guarantee QoS integrally from end to end carried by MSS-ASN-CSN. The method provides different services for WiMax users.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for realizing service quality assurance in a wireless communication system. Background technique [0002] In existing wireless communication systems, such as WCDMA (Wideband Code Division Multiple Access) systems and CDMA (Code Division Multiple Access) systems, different quality of service guarantees are usually provided to different users according to needs, so as to provide users with different Serve. [0003] With the development of wireless communication technology, the WiMax (Worldwide Interoperability for Microwave Access) system has also become a new wireless broadband access technology to be studied in wireless communication systems. The WiMax system mainly includes ASN (Access Service Network), CSN (Connection Service Network) and MSS (Mobile Terminal), wherein: the ASN is used to provide a set of network functions for WiMAX terminals to provide...
