METHOD, DEVICE AND SYSTEM FOR DISTRIBUTING AND ACQUIRING THE LOCATION AREA IDENTIFICATION INFORMATION

摘要

A method, a device and a system for distributing and acquiring the location area identification (LAI) information are provided in the present invention, wherein the method includes the steps: if a control plane entity (CPE) determining the distributed LAI information as the first LAI information, then sending a message with a special identification information to a UE according to the first LAI information; the UE acquiring the corresponding first LAI information according to the special identification information after receiving the message with the special identification information. The above CPE sends the special identification information to the UE instead of sending the LAI information repeatedly in the case of determining that the LAI information distributed to the UE is the same as the one distributed before, thus it will not introduce the unnecessary burden to the network, especially in the case that the CPE distributes the excessive LAI information, and it will save more air interface resources.
