Abstract
The invention discloses a position updating method used in a microwave access worldwide interoperability certification system, comprising the following steps: in the process of updating terminal position, sending the current position information of the terminal to a functional entity saving the mobility restricted parameter of the terminal on the network side by a paging agency; judging the mobility restriction by the functional entity saving the mobility restricted parameter of the terminal according to the position information and the locality preserving mobility restricted parameter of the terminal; if the terminal can not satisfy mobility restricted condition, indicating the failure of updating the terminal position by the functional entity saving the mobility restricted parameter of the terminal. The method of the invention can judge the mobility restriction when position is updated, which prevents that the terminal is mistakenly allowed to update position in a non-authoritative zone and ensures the availability of the mobility restricted parameter and the safety of the network.
Description
Technical field
The present invention relates to the communications field, relate in particular to the location updating method in a kind of WiMAX (Worldwide Interoperabilityfor Microwave Access, the interoperability authentication of the inserting of microwave whole world) system.
Background technology
Defined idle pulley in the WiMAX system at present.During terminal access idle mode, the aerial connection of its correspondence and the connection of Access Network all are released, and terminal information is kept in the anchoring paging controller, so terminal does not take air resource and access network resources; Enter the terminal periodic reception downlink broadcast message of idle pulley, when a plurality of base station area move, need not register, therefore can save the energy consumption of terminal in specific base stations.
After entering idle pulley, terminal can be carried out the position and be upgraded when satisfying following condition: paging group is upgraded, cycle is upgraded (being that timer then upgrades), the shutdown position is upgraded, MAC Hash skip (change of media access control layer Hash) threshold value is upgraded, and MBS Zone (multicast broadcast service zone) changes the position to be upgraded.
When occurrence positions upgraded, the paging agent of terminal can send position updating request to the anchoring paging controller of terminal; After anchoring paging controller is received position updating request, can carry out interacting message with anchoring authentication device and obtain AK Context (authorization code context); Have only from anchoring authentication device successfully to obtain AKContext, anchoring paging controller is new terminal current position information.
Fig. 1 is that the WiMAX system terminal carries out the schematic flow sheet that the position is upgraded in the prior art, comprises the steps:
101: paging agent sends location update request message to anchoring paging controller (each anchoring paging controller all has the location register of a correspondence, and location register is used for writing down the information of terminal of idle mode); Have information such as current base station sign in the location update request message; After this message is sent from paging agent, may arrive anchoring paging controller through one or more relaying paging controller;
102: anchoring paging controller sends context request message to anchoring authentication device, to obtain AKContext;
103: anchoring authentication device sends context response information to anchoring paging controller, has AK Context in this response message;
104: anchoring paging controller sends the position and upgrades response message to paging agent, and this response message has AK Context, and this message may arrive paging agent through one or more relaying paging controller;
105: base station (paging agent is positioned at the base station) according to the distance measurement request message verification succeeds of AK Context to terminal after, send ranging response message to terminal; Paging agent sends position renewal acknowledge message to anchoring paging controller simultaneously; Have the position in this message and upgrade result's sign; Acknowledge message is upgraded in the position may arrive anchoring paging controller through one or more relaying paging controller;
106: after anchoring paging controller receives that acknowledge message is upgraded in the position, be designated success if the result is upgraded in the position, then anchoring paging controller upgrades location information of terminals.
Existing WiMAX system does not consider the mobility limited features of terminal when upgrading in the position.So-called mobility restriction is meant that the operator of WiMAX system does not have movible licence plate, need carry out the mobility restriction to its user terminal; Even perhaps there is movible licence plate in operator, but the operator uses the WiMAX network in order to attract low end subscriber, makes it use the WiMAX network with cheap price under the ambulant condition of the user terminal that limits the type.
That is to say, adopt existing location updating method,, might allow its zone beyond in this specific region to carry out the position mistakenly and upgrade for the terminal that is limited in the specific region.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of location updating method that terminal is carried out the mobility restriction is provided.
