Embodiment Construction

[0024] The specific implementation manners of the present invention will be described below in conjunction with the accompanying drawings.

[0025] As shown in Figure 1, it is a schematic structural diagram of a trunking communication system used in the embodiment of the present invention. This embodiment takes a GSM-based trunking scheduling system as an example for illustration, but the scope of application of the present invention is not limited thereto, and the present invention Applicable to digital trunking communication systems of TETRA, IDEN and other standards.

[0026] In Figure 1, the call attribute data storage network element of the trunking system stores the call attribute data, including group ID, call priority, call area, call dispatcher information, inactive timer duration, and call encryption information. The trunking system call attribute data storage network element may be a network element with related functions such as GCR. In this embodiment, the GCR is...

Abstract

The invention relates to a method for realizing call service in group communication. Wherein, in the communication, there are several users in communication and in same group, the first group members use ascending signal channel to send message, and the members of other groups use descending signal channel to receive message. And the invention is characterized in that based on the priority information of group members set in the data memory network unit in group system, distributing ascending signal channel for the group members. The invention can realize signal channel share in one region, all group members of said region use one transmission signal channel (TCH signal channel). And in one call, it processes half-duplex communication, and other group members occupies ascending to communicate that at one time, there is one group member uses ascending to communicate, while the high-priority group member can take the communication priority of low group members.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for realizing a group communication call service. Background technique [0002] The trunking communication system was born in the late 1970s to the early 1980s. Its working method is similar to the telephone switching system, and the channel is automatically assigned to the user through the central switching station as needed. The basic principle of trunking communication is: the central controller centrally controls and manages each channel in the system, and dynamically assigns the idle channel to the trunking user who initiated the call in a dynamic manner, and returns the channel to the waiting trunking group after the call is completed User usage, therefore, greatly increases channel usage. [0003] Cluster users can use a set of trunking communication systems together according to the needs of different departments, and establish communication systems for government aff...
