example 1

[0050] When the mobility management device determines that the mobile terminal is switched from the 3G network to the 4G network, it acquires a predetermined amount of LAI information in the received TAU message, and selects LAI information that meets predetermined update conditions from the predetermined amount of LAI information. , to replace the LAI information corresponding to the TAI information in the TAI-LAI mapping table.

[0051] Specifically, the mobile management device may determine the occurrence times of each LAI information in the predetermined amount of LAI information according to the predetermined amount of LAI information, and then select the occurrence times of each LAI information within a predetermined time interval based on the occurrence times of each LAI information. The LAI information with the most occurrence times is used to replace the LAI information corresponding to the TAI information in the TAI-LAI mapping table.

[0052] For example, the mobil...

[0081]For example, the frequency of occurrence determination submodule determines the frequency of occurrence of each LAI information in the 100 LAI information according to the 100 LAI information in the TAU message, and then, the LAI information selection submodule selects based on the frequency of occurrence of the 100 LAI information The LAI information that occurs most frequently in a day or a week is selected as the LAI information that occurs most frequently in a day or a week, and then the LAI information replacement submodule uses the LAI that occurs most frequently in a day or a week information to replace the LAI information corresponding to the TAI information in the TAI-LAI mapping table.

Abstract

The invention discloses a method and device for updating a TAI-LAI mapping table. The method for updating the TAI-LAI mapping table in mobile management equipment of a wireless communication network comprises the following steps: receiving TAU messages from one or more mobile terminals, wherein the mobile terminals have the same TAI information; according to the LAI information in the received TAU messages and the TAI information of the mobile terminals, updating the TAI-LAI mapping table. According to the method, the TAI-LAI mapping table is updated according to the LAI information in the received TAU messages of the mobile terminals and the TAI information of the mobile terminals, so that the less network resources are consumed, and the call establishing time is shorter.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and device for updating a TAI-LAI mapping table. Background technique [0002] Since the LTE (Long Term Evolution, Long Term Evolution) standard only supports PS (Packet Switch, Packet Switching) services, operators need to reorganize voice call networks to support voice call services for LTE terminals. Among them, the CSFB (Circuit Switched Fallback) solution is a solution when there is no IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) to support voice call services. In the CSFB solution, the LTE network only provides data Service, when the mobile terminal initiates a voice call or receives a voice call, the mobile terminal falls back to the CS (Circuit Switched, circuit switched) domain to perform the voice call service. [0003] There is a TAI-LAI mapping table in MME (Mobility Management Entity, mobile management unit), where TAI (Tracking Area Id...
