Simple signaling cluster communication method

Abstract

The invention discloses a simple signaling cluster communication method, which comprises the following steps that: (1) a base station encodes a control instruction into a simple signaling also including a channel code; (2) the base station sets a code corresponding to the simple signaling; (3) modulating the code on an emission carrier; (4) a terminal receives and demodulates the acquired code; (5) the terminal acquires the control instruction according to a preset control instruction and simple signaling code corresponding table; and (6) the terminal completes cluster communication operationaccording to the control instruction. The step (6) of completing the cluster communication operation comprises that: after making a call, any terminal cooperates with the base station to transfer a control channel, performs communication by taking an original control channel as a service channel, and switches to the original control channel after the communication is completed. A cluster functionis realized by adding a software module into each of the base station and the terminal of a low-cost conventional communication system; and a channel attribute is dynamically switched according to service changes to realize frequency point reuse and reduce the channel congestion, so that the utilization rate of wireless channel resources and equipment is increased.

AI Technical Summary

Problems solved by technology

[0012] The existing wireless communication system that can realize the trunking function can realize flexible grouping and channel multiplexing, but the technology is complex and expensive

Conventional wireless communication systems in the prior art have fixed frequency points, and when multiple frequency points are grouped according to frequency points, flexible grouping and channel multiplexing cannot be realized; if the conventional system is used to realize the trunking function, it is generally necessary to set up multiple sets of conventional relay stations to realize multiple Frequency point forwarding, this method is more costly
