Problems solved by technology

In this way, multiple terminals can answer at the same time, but this can only be half-duplex. If one of the terminals needs to talk, it needs to apply to occupy the channel
Moreover, the existing mobile communication network does not have the functions of dispatching and group calling. If it is necessary to realize trunking services, the terminals and base stations in the mobile communication network will have to und

Embodiment Construction

[0030] Below in conjunction with accompanying drawing, the implementation of technical scheme is described in further detail:

[0031] At the switching center of the communication system (such as: the MSC of the mobile communication system, the local switching center LS and PBX of the PSTN), a cluster server (but not limited to this, the location of the cluster server is not limited), and the interface between the switching center Use standard signaling interfaces acceptable to switching centers, such as figure 1 As shown, the MAP interface between mobile networks is used in the mobile communication system, and the E interface in IS41 is used in the CDMA system. The cluster server is equivalent to a switch in the PSTN network or another MSC in the PLMN. Similarly, the cluster server can be in a fixed network, and can also complete cluster services.

[0032] The internal structure of the cluster server is as follows figure 2 As shown; the main function of the cluster server ...

Abstract

The mobile communication system includes base station receiver and transmitter, base station controller, mobile switching center/visiting location register and attribute location register/authority identifying center, as well as group server for group service control and dispatching stage. The group service is connected to mobile switching center via Map interface or E interface in IS41 to used as one part of the mobile switching center. The present invention has the advantages of low construction cost, capacity of group service of hetero network including various mobile communication networkand fixed communication network, capacity of full duplex group call and dispatching, etc.

Description

technical field [0001] The invention relates to a mobile communication system, provides a mobile communication system and a method for realizing trunking services, and is applicable to other types of public communication systems. Background technique [0002] The most important feature of trunking business is the ability to dispatch and group call. The function of dispatching means that the dispatching station calls up a certain number of terminals (wired or wireless) at the same time, so that these terminals can talk at the same time; Call up and talk at the same time, so as to achieve the effect of "one call, one hundred responses". Cluster services are widely used by private network users, such as the military, railways, and public security. [0003] In order to realize the trunking service, the traditional wireless system centrally modulates the called channels onto one channel, and all terminals listen to this channel, and only one terminal can occupy the channel to s...
