Group call method and group call register for the third generation partner program network

Abstract

The related group calling method and register in 3GPP network comprises: as only using group mark to generate group calling reference, the typical way is to use directly the group mark as the calling reference; thereby, the group mark is equal to the group calling reference, and both can be selected as 8-order decimal numbers. Compared with current technology, this invention enlarges cluster capacity by hundreds times, simplifies GCR management.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to the group call technology in the 3rd Generation Partnership Project (3rdGeneration Partnership Project, referred to as "3GPP"). Background technique [0002] Global System for Mobile Communication (GSM for short) is a standard launched by the European Standardization Committee in 1992. It adopts digital communication technology and unified network standards to ensure communication quality and to develop more of new services for users to use. GSM-R, that is, the GSM system serving railways, is a railway-specific mobile communication system formed by adding trunking communication functions on top of GSM. The added trunking functions of the GSM-R system mainly include Advanced Speech Call Item (ASCI for short) functions defined by the GSM Phase 2+ (GSM Phase 2+) standard. [0003] The ASCI function includes three basic services of dedicated mobile communications: Enhanc...

Problems solved by technology

[0012] In practical application, the above scheme has the following problems: the method of voice group call according to the existing group call reference wastes a lot of group number resources, and is not suitable for public network trunking systems

[0013] The main reason for this situation is that in the prior art, the voice group call in the network is uniquely identified by the group call reference. The group call reference is composed of the group identifier and the group call area identifier. The same user initiates the same group call , can correspond to different group call areas, so that the group call has greater flexibility. However, for some networks, such as in the actual application of public network clusters, users mainly initiate a group call in a fixed area. It needs to correspond to different group call areas. At this time, it is redundant to divide the group call reference into group call ID and group call area ID, and greatly reduces the number of group call reference combinations, wasting a lot of group number resources

It is not suitable for public network cluster systems with many users and many users need to allocate fixed number segments
