A paging method, location updating method and device

Abstract

A paging method, which can reduce system paging signaling overhead and save system paging resources; the method includes: a base station receives a paging message, and the paging message carries a tracking area identifier; if the paging message contains If the tracking area ID of the base station is the tracking area ID of the base station, the base station paging the terminal; if the tracking area ID in the paging message is the tracking area ID of the relay station under the jurisdiction of the base station, the base station indicates the The relay station paging the terminal. A location update method is also disclosed, which can reduce the signaling load brought by location update. The method includes: a relay station generates a system message, and the system message includes the tracking area identifier of the relay station; the relay station broadcasts the system message , triggering a terminal entering a cell under the jurisdiction of the relay station to initiate a location update request. The invention also discloses a base station, a relay station, a communication system and a mobile management entity.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a paging method, a location update method and equipment. Background technique [0002] In 2006, ITU-R (ITU-Radiocommunication Sector, ITU Radiocommunication Sector) officially named B3G (Beyond3G, fourth-generation mobile communication) technology as IMT-Advanced (International MobileTelecommunications-Advanced, International Mobile Communications Advanced System) technology. On the one hand, IMT-Advanced puts forward very high requirements on the system capacity; on the other hand, the large-bandwidth spectrum that can support such a high capacity can only be found in higher frequency bands, and the path loss and penetration loss of such high frequency bands are relatively low. Large and difficult to achieve good coverage. In order to meet the capacity requirements of IMT-Advanced, the LTE-Advanced system proposed by 3GPP (3rd Generation Mobile Group, 3rd Generation Part...

AI Technical Summary

Problems solved by technology

[0009] Considering that there are likely to be many terminals under a mobile relay station, and each terminal must perform a location update at almost the same time, it will cause a huge signaling burden on the air interface in a short time, which will affect normal voice and data. Communication

The mobile relay station itself may be moving at high speed, so it will enter the cell coverage of another base station in a short period of time, and the above-mentioned large number of terminals repeatedly perform location updates at the same time, resulting in excessive signaling load
