Abstract:
1. A method for entering an idle mode, which is used in a Worldwide Interoperability for Microwave Access (WiMax) system, wherein the method comprises: during the procedure of a terminal enter to idle mode from active mode, a paging agent of the terminal sending current location information of the terminal and mobility restriction parameters of the terminal to a mobility restriction parameter storage network element; performing a mobility restriction judgment to the terminal according to the current location information and the mobility restriction parameters; and determining if the current location information satisfies a mobility restriction condition set by the mobility restriction parameters; and the mobility restriction parameter storage network element saving the mobility restriction parameters if the mobility restriction condition is satisfied; wherein the mobility restriction parameter storage network element is an anchor paging controller, an anchor authenticator, or a function entity including a function of the anchor paging controller and a function of the anchor authenticator; wherein the mobility restriction parameters comprise one or more of the following: an identifier list of base stations allowed or forbidden to be accessed, an identifier list of access service networks allowed or forbidden to be accessed, times of successive handover, an allowed minimum interval for the handover, an allowed or forbidden re-orientation region of a serving base station, and a service continuity supporting identifier of the re-orientation region; wherein the location information comprises a base station identifier; the mobility restriction parameters comprise: an identifier of the base station allowed to access or an identifier of the base station forbidden to access; and the terminal is determined to satisfy the mobility restriction condition only when the base station identifier belongs to the identifier of the base station allowed to access of the mobility restriction parameters or does not belong to the identifier of the base station forbidden to access of the mobility restriction parameters; or the location information comprises an identifier of an access serving network; the mobility restriction parameters comprise: an identifier of the access serving network allowed to access or an identifier of the access serving network forbidden to access; and the terminal is determined to satisfy the mobility restriction condition only when the identifier of the access serving network belongs to the identifier of the access serving network allowed to access of the mobility restriction parameters or does not belong to the identifier of the access serving network forbidden to access of the mobility restriction parameters.
