Problems solved by technology

[0007] When opening a group call on the GSM public network, there are many MSCs on the GSM public network, and the number of groups is relatively large. Each Relay MSC is configured with the information of the Anchor MSC corresponding to all group calls, which will lead to a large amount of configuration and error-prone problems, waste network resources and processing costs, and also make the reliability of network processing relatively low

Abstract

The invention discloses a method for updating the location of a mobile terminal. The method comprises the following steps: a visitor location register (VLR) forwards the location updating request of a roaming mobile terminal to a home location register (HLR); the HLR provides the group information of the mobile terminal to the VLR, and the group information comprises the information related to the mobile switching center of the home land Centrex service of the mobile terminal; the VLR records the group information, and returns the location updating response to the mobile terminal. The invention further discloses a group calling method of the roaming mobile terminal, the VLR, the HLR and a communication system. By adopting the invention, the network resource and the processing cost are saved; the reliability of network processing is improved; and the group calling of the roaming mobile terminal also can be realized conveniently and rapidly.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for updating the location of a mobile terminal. Background technique [0002] A mobile switching center (Mobile Switching Center, MSC) is used for call control and mobility management, such as managing call states related to connection control in the media gateway. VLR (VisitorLocation Register, Visitor Location Register) of MSC can accommodate various subscription data of mobile users. In order to provide trunking services, the MSC server needs to process and identify trunking calls. [0003] Due to the extensive use of services such as group calls and multicasts in trunking communications, the prior art has set up a group call register (Group Call Register, GCR) for storing voice group call related Data, providing necessary information for trunking scheduling communications such as VGCS (Voice Group Call Service) and VBS (Voice Broad...
