Method for releasing idling-resource in WiMAX system

Abstract

The method includes steps: mobile station sends message of service request to service base station, network gateway of service access, and relevant equipment of net element; the equipment of net element returns back message of service response to the network gateway of service access, service base station, and mobile station; when receiving message of service response, service base station starts first timer, and after the first timer is time-out, the service base station releases idle resource; based on triggering condition, network gateway of service access releases idle resource. Through setting up triggering condition including timer triggering and message triggering, the invention overcomes things such as resource exhaustion, confusion between net elements caused by no clear definition how to releases idle resource in WiMAX system from occurring.

Description

technical field [0001] The present invention relates to the field of Worldwide Interoperability for Microwave Access (WiMAX for short), and more specifically, relates to a method for releasing idle resources in a WiMAX system. Background technique [0002] Global Interoperability of Microwave Access is a wireless metropolitan area network access technology based on the IEEE 802.16 standard. With the vigorous development of Internet services and the wide application of wireless networks, the WiMAX system has received a lot of applications and attention due to its good wireless access characteristics. [0003] figure 1 It is a schematic diagram of the network architecture of WiMAX applied to mobile communication. The WiMAX system at least includes an Access Service Network (ASN for short), a Connectivity Service Network (CSN for short) and a Mobile Station (MS for short). Among them, MS is a mobile user equipment, which is used by users to access the WiMAX system, so it can...

[0011] In the above two processes, when the MS switches to a new device ( figure 2 When the middle finger switches to the target GW, image 3 The middle refers to the MS roaming to other GWs), and there is no clear way to release the context resources in the SGW. If the context resources in the SGW are not released at this time, or are released immediately, unpredictable problems will occur. For example, the context resources in the SGW If the context resource is not released all the time, it may lead to resource exhaustion; or if the context resource in the SGW is released immediately, when the user switches back in a short time, there is context information in the SBS, but in the There is no context information on the SGW, so there will be inconsistencies between the two network element devices, resulting in a disordered state
