Problems solved by technology

[0012] The existing WiMAX system does not take into account the mobility restriction characteristics of the terminal when updating the location
The so-called mobility restriction means that the operator of the WiMAX system does not have a mobile license and needs to restrict the mobility of its user terminals; Under the condition of the mobility of the user terminal, it can use the WiMAX network at a low price
[0013] That is to say, using the existing location update method, for a terminal that has been restricted in a specific area, it may be wrongly allowed to perform location update in an area outside the specific area

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 theterminal; 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 [0001] The present invention relates to the communication field, in particular to a location update method in a WiMAX (Worldwide Interoperability for Microwave Access, microwave access global interoperability certification) system. Background technique [0002] At present, the idle mode has been defined in the WiMAX system. When the terminal enters the idle mode, its corresponding air connection and access network connection are all released, and the information of the terminal is stored in the anchor paging controller, so the terminal does not occupy air resources and access network resources; The terminal in the mode periodically receives downlink broadcast messages, and does not need to register with a specific base station when moving in the area of ​​multiple base stations, so the energy consumption of the terminal can be saved. [0003] After entering the idle mode, the terminal will update the location when the following conditions are met: paging gro...
