Problems solved by technology
Although the group connection service can solve the problems of PTT button conflict and display error of the speaker number, the systems that require intercommunication are all TETRA standard trunking communication systems, and their business processes are complex and error-prone. Difficult to promote in practical application

Embodiment Construction
[0039] In order to fully understand the technical content of the present invention, specific embodiments are given below, and the technical solutions of the present invention are introduced and explained in detail in conjunction with the accompanying drawings.
[0040] In this embodiment, there are four cluster communication systems A, B, C, and D, which can be interconnected through interconnection interfaces. Among them, the A1 talk group of system A, the B3 talk group of B system, the C1 talk group of C system, and the D4 talk group of D system need to communicate with each other; the B1 talk group of B system, the C3 talk group of C system, and the D2 talk group of D system need to communicate with each other; The talkgroup, the C2 talkgroup of the C system, and the D1 talkgroup of the D system need to communicate with each other; the A2 talkgroup of the A system, and the D3 talkgroup of the D system need to communicate with each other. For this reason, a group intercommun...

The invention provides a method for realizing cross-system intercommunication of different call groups among trunked communication systems. The method includes that a group intercommunication gateway is set up among the trunked communication systems, communicates with each trunked communication system through interlink interfaces, configures and maintains a list of group correlation numbers, each group correlation number correlates with a plurality of call groups needing intercommunication and belonging to different trunked communication systems, each trunked communication system maintains a record of corresponding relationship between a call group number that the trunked communication system belongs to and a group correlation number, and group calling of cross-system intercommunication takes the group intercommunication gateway as a call control center. By the method, cross-system intercommunication group calling of different call groups can be realized without collision of voice sending authorization and mistakenly displaying of speaking parties, and group calling failure caused by various abnormal conditions can be avoided.
Description
technical field [0001] The invention belongs to the technical field of trunking communication, and mainly relates to a method for realizing cross-system intercommunication of different talk groups among trunking communication systems. Background technique [0002] The trunking communication system belongs to professional mobile communication, and it is a radio dispatching command communication system that shares resources, shares costs, and shares channel equipment and services. It represents the development direction of a dedicated mobile communication network, one of the communication systems. The biggest feature of the trunking communication system is that the voice communication adopts the PTT (Push To Talk) button form, and the channel is connected through a push-to-talk method, the connection speed is fast, and it can support group calls (Group Call). [0003] Group call is the most important dispatching service and command method in the trunking communication system. ...
