A METHOD, SYSTEM AND DEVICE FOR RELEASING RESOURCE IN THE WORLDWIDE INTEROPERABILITY FOR MICROWAVE ACCESS NETWORK

摘要

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.
