Problems solved by technology

However, in the current WiMax system, between the BS and the ASN GW, and between the ASN GW and the ASN GW, it is not possible to completely provide different QoS guarantees for different users or different sessions
[0005] Therefore, it is currently impossible to provide different quality of service guarantees for different users and different sessions in the WiMax system

Embodiment Construction

[0038] The core of the present invention is to expand the message in the wireless access network, increase session identification and service quality information, so that the establishment and release management of the data path in the access network can be realized based on the session, so as to facilitate broadband wireless access such as WiMax. Enter the system to implement QoS guarantee for the corresponding session.

[0039] Take the WiMax system as an example. The basic QoS negotiation process, the R6 interface data path establishment process, and the R4 interface handover process are currently defined in the system.

[0040] Among them, in the basic QoS negotiation process, the data path establishment process and QoS negotiation process between Serving ASN GW (Serving ASN GW) and Anchor ASN GW (Anchor ASN GW) are not defined. In this way, when an operator needs to separately apply a specific Anchor ASN GW for billing verification or other applications, the corresponding dat...

Abstract

A method for providing distinguishing service in communication network mainly includes the following steps: when the data path used in the session (service stream) is required to release, a releasing data path message including session identifier information is transmitted, then the corresponding session data path is released by respective network entities based on the session identifier information in the releasing data path message. The releasing can be initiated not only by BS, but also by ASN GW. Thus, the invention enables the WiMax signaling process to support different QoS service for different session in the same MSS. Meanwhile, the invention adds the initiating process of session establishing from ASN-GW within WiMax to BS, and the application condition of establishing data path among WiMax ASN GW. In conclusion, in the invention, all of the data path establishing request / response message may carry QoS information to incorporate the existing QoS negotiation local process.

Description

Technical field [0001] The present invention relates to the technical field of network communication, in particular to an implementation method for providing differentiated services in a wireless access network. Background technique [0002] In the existing wireless communication systems, such as WCDMA (Wideband Code Division Multiple Access) systems and CDMA (Code Division Multiple Access) systems, different users are usually provided with different service quality guarantees as needed, so as to provide users with different service. [0003] With the development of wireless communication technology, the WiMax (Global Interoperability for Microwave Access) system has also become a new wireless broadband access technology that is scrambling to study in wireless communication systems. The WiMax system mainly includes ASN (Access Service Network), CSN (Connection Service Network) and MSS (Mobile Terminal), where: the ASN is used to provide a collection of network functions for WiMAX...
