Embodiment Construction
[0023] In order to reduce the overhead of signaling and effectively reduce the signaling load of the network, the embodiment of the present invention provides a method for generating a location area list, the method includes: counting the association relationship between each location area and its adjacent location areas, When the UE moves to a target location area other than its currently saved location area list, according to the association relationship, a location area list including the target location area is generated, and the generated location area list information is sent to the UE. In the embodiment of the present invention, the service management device determines the association relationship between each location area and its adjacent location areas by recording the mobile behavior of each UE, and generates a location area list according to the association relationship. Since the location area in the location area list It has a certain correlation with its adjacent...

The invention discloses a method and a device for generating a location area list, which solve the problem of high signaling expense and large network signaling load during updating user equipment (UE) and service management equipment in the location area in the prior art. The method comprises the following steps of: making a statistic of association relation of each location area and adjacent location area thereof; and when the UE is moved to a target location area out of the current location area list, determining a location area list where the target location area exists according to the association relation, and sending the determined location area list information to the UE. The embodiment of the invention determines the association relation between each location area and adjacent location area thereof by making a statistic of the mobility pattern of each UE; the location area list generated by the association relation contains several location areas highly related to the association relation of the target location area where the UE moves, so that signaling expense during updating of the UE and the service management equipment in the location area can be effectively saved, and signaling load of the network is decreased.
Description
technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method, system and device for generating a location area list. Background technique [0002] When the user equipment (User Equipment, UE) moves from the first location area to the second location area under the coverage of the Evolved Universal Terrestrial Radio Access Network (Evolved Universal Terrestrial Radio Access Network, E-UTRAN), due to its saved location The area information is the information of the first location area. Therefore, when the UE is located in the second-generation mobile communication technology (Second Generation, 2G) or third-generation mobile communication technology (3rd-Generation, 3G) network, the UE will send the wireless control device - The base station controller (BaseStation Controller, BSC) or the radio network controller (Radio Network Controller, RNC) sends a location area update request, the radio control device deter...
