Method for releasing resources in microwave access global internet

Abstract

The invention is applied to the wireless communication technique. A method, system and device for releasing resource in the worldwide interoperability for microwave access network enables the anchor authenticator releasing the related resource in time when a mobile station leaves the network. The anchor PC / LR manages the mobile stations and if it finds a mobile station leaves the network, it informs the anchor authenticator a message carrying one or more identifiers of the mobile station which leaves the network, and the anchor authenticator deletes the safe information of the corresponding mobile station according to the identifiers. The invention can release system resource in time and increase the utilizing efficiency of the system resource by deleting the safe information. When the anchor PC / LR informs the anchor authenticator that the mobile station leaves the network, the anchor PC / LR can use either a new added message or an existing message that is expanded.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to microwave access global interoperability technology. Background technique [0002] With the development of communication technology and the increase of user demand, data services have been developed rapidly, and the rapid growth of data traffic has made people's demand for communication bandwidth increasingly high. Broadband access is showing a huge market to the industry. In order to break through the bandwidth bottleneck of the access network, various broadband access technologies have been introduced. [0003] Compared with the wired access method, the Broadband Wireless Access (BWA) technology using the wireless access method has obvious advantages such as flexibility, convenience, mobility and less investment. (The Third Generation, referred to as "3G"), broadband wireless local area network (Wireless Local Area Network, referred to as "WLAN") and broadband wireless metr...

Problems solved by technology

[0014] In practical applications, the above solution has the following problems: In the WiMAX system, there is a waste of resources when the MS paging in IDLE mode

[0015] The main reason for this situation is that when the MS enters the IDLE mode, some security information of the MS will still be retained on the anchor authenticator of the MS. When the MS leaves the network, including MS loss or MS shutdown, the anchor The authenticator does not know that the MS has left the network, and still retains the security-related information of the MS, which undoubtedly forms a waste of resources
