Position updating method, terminal, base station and system

Abstract

An embodiment of the invention provides a position updating method, a terminal, a base station and a system. The method comprises steps as follows: when a position update aggregation function is started, if an AD (aggregation device) role is determined to be played, an aggregation broadcast message is sent through an Ad hoc network; position updating requests sent by at least one mobile terminal through the Ad hoc network are received; the received position updating requests sent by the at least one mobile terminal are aggregated into an aggregation position updating request; and the aggregation position updating request is sent to the base station through a cellular network. Position updating requests of other mobile terminals can be collected through the Ad hoc network, and then the position updating requests are sent to the base station through the cellular network in a manner of one aggregation position updating request, so that an occupied RACH (Random Access Channel) resource is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a location updating method, terminal, base station and system. Background technique [0002] With the development of mobile cellular communication, the number of network users is increasing, while the setting of cells and location area / routing area / registration area is getting smaller and smaller, which leads to higher and higher cost of location management. If the location update fails, the network lacks effective location information of the terminal, which will lead to call failure, increased call loss, and reduced network performance. With the emergence of high-capacity and high-speed moving vehicles, when the large-capacity vehicles pass through the location area, it will cause a large number of location update requests instantaneously generated by the group mobile terminals on the vehicles. In addition to the above-mentioned large number o...

Problems solved by technology

[0004] However, in the above-mentioned existing solutions, a Mobile Relay Station (MRS) must be deployed, and a GMC is required to maintain the mobile group. The MRS first obtains the mobile terminals in the group from the GMC, and then assigns the location of the mobile terminals in the group The update request is sent to the base station (Base Station, BS for short)

In addition, since users on the public transportation system get on and off from time to time, the ground users who get on the bus are connected to the MRS, and the car users who get off are connected to the external BS, and the group maintenance costs are very large in mobile groups that change frequently , and cannot effectively keep the information synchronization between MRS and BS
