Paging method, system, mobility management entity and base stations

Abstract

The present invention discloses a paging method, a paging system, a mobility management entity and a base station and belongs to the wireless communication field. The paging method includes the following steps that: the mobility management entity acquires the information of a first base station where the last communication of user equipment is carried out; and the mobility management entity transmits a paging message to the first base station according to the information of the first base station, and correspondingly, the first base station pages user equipment within the range of a current cell according to the paging message. The first base station may also forward the paging message to the neighbor cell base stations of the first base station, and correspondingly, the neighbor cell base stations page user equipment within the ranges of the respective cells of the neighbor cell base stations. With the paging method, paging system, mobility management entity and base station of the invention adopted, signaling load between the mobility management entity and the base station and the signaling load of the air interfaces of the base station can be effectively reduced.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a paging method and system, a mobility management entity and a base station. Background technique [0002] With the rapid development of the mobile Internet and the popularization of mobile smart terminals, the data throughput of mobile services is growing in a blowout manner, and the wireless access LTE (Long Term Evolution, Long Term Evolution) technology is born. [0003] LTE wireless network architecture such as Figure 1A It shows that it cancels the RNC (Radio Network Controller, Radio Network Controller) node in the UMTS (Universal Mobile Telecommunications System, Universal Mobile Communications System) network, and the network architecture becomes flatter and simpler. The entire radio access network E-UTRAN (Evolved Universal Terrestrial Radio Access Network, Evolved Universal Terrestrial Radio Access Network) is only composed of eNodeB (Evolved Node B, evolved base...

AI Technical Summary

Problems solved by technology

[0008] The existing paging method based on tracking area or tracking area list has a large paging range, which will greatly increase the signaling load of the network and may cause a "signaling storm" in the network

In addition, all base stations in the tracking area or tracking area list send paging messages to the user equipment through the air interface, which will increase the signaling load of the air interface
