In the prior art, a plurality of base stations are divided into a paging zone, and a plurality of paging zones are by a paging controller (Paging Controller is called for short PC) unified management.When terminal had downlink service data to arrive, paging controller was responsible for initiating paging, and all base stations of terminal place paging zone all will send paging broadcast message, and terminal exits from idle mode after receiving beep-page message, reenters network and downlink data receiving.Therefore, terminal need be finished multiple position and upgrades (Location Update) process at ordinary times, so that register information such as the paging zone position at its current place and paging parameters to paging controller.
When idle pulley, through consultation, part or all of business and operation information that the base station can be current with terminal comprise that safe context information remains into paging controller, so that quicken into network process when networking again.
For fear of message oral instructions aloft disturbed or personation sowing time, the 802.16e system has stipulated that corresponding security mechanisms is used for the transmission of protected data and message, and wherein message authentication code (HMAC/CMAC) can prove the validity of message.In order to verify message authentication code, need to obtain the safe context information that share terminal and base station, as authorization key (Authorization Key is called for short AK) etc.The authentication person (Authenticator) who is positioned at network side is responsible for producing above-mentioned safe context information.
The base station can obtain to belong to the safe context information of this terminal from paging controller or authentication person (Authenticator), the validity and the echo reply of checking distance measurement request message (RNG-REQ) continue to keep these safe context information so that terminal is used when position renewal next time simultaneously.Base station and carrying out after new position upgrades under terminal moves to other paging zone, paging controller can send the safe context information of this terminal that the original base station deletion of backbone message informing keeps, in order to avoid the storage resources of waste base station.
But " ping-pong " that this mode can't avoid terminal to produce in moving process, being terminal returns behind the paging zone that leaves under certain base station once more, at this moment the base station has been deleted the safe context information of this terminal that keeps, the safe context information that therefore needs once more paging controller or authentication person (Authenticator) to network side to ask this terminal.
Summary of the invention
At defective that exists in the prior art and deficiency, the objective of the invention is to propose a kind of 802.16e system idle pulley location updating method, can effectively reduce the interacting message of base station and network side, quicken the idle pulley position updating process, can not cause the storage overhead of base station significantly to increase simultaneously.
For addressing the above problem, the present invention proposes a kind of idle pulley location updating method, may further comprise the steps:
(1) terminal is initiated distance measurement request message to the base station;
(2) described base station sends location update request message to paging controller;
(3) described paging controller upgrades response according to described position updating request information to described base station home position;
(4) described base station judges whether the safe context information of described terminal correspondence, if have then base station contextual information safe in utilization is verified described distance measurement request message, if do not have then base station requests obtains the safe context information of described terminal correspondence, and use the described distance measurement request message of described safe context Information Authentication;
(5) confirmation is upgraded to described paging controller home position in described base station; Also comprise: for the base station is provided with timer;
Receive the safe context information of described terminal correspondence when the base station after,, and start the timer of described terminal correspondence with described safe context information cache;
