Abstract

The invention discloses a digital cluster communication system for private network communication, comprising a terminal and a base station connected with the terminal through an air interface, whereinthe working state of the terminal comprises a transfer state. The terminal receives the signals of the base station and transmits the signals to other terminals or receives the signals of other terminals and transmits the signals to the base station when the terminal works in the transfer state. The terminal can be used as a transfer station so that the communication scopes and capacities of a handset, a car machine and a fixed station in the system are effectively extended. Therefore, the digital cluster communication system 100 for private network communication is suitable for dynamic networks in emergent communication conditions and self-establishment and self-maintenance communication networks when a certain cluster is far away from the base station, and has a large coverage radius.

Description

technical field

[0001] The invention relates to the communication field, in particular to a digital trunking communication system for private network communication. Background technique

[0002] Trunking communication system is a dedicated dispatching mobile communication system that shares wireless channels. It adopts multi-channel sharing and dynamic channel allocation technology in modern communication, and has dispatching functions such as individual call, group call, and broadcast call. Its characteristics are call It is fast to set up, users have different priorities, call time is limited, and it has the function of remote death and resurrection.

[0003] Trunking communication has been used in our country for more than ten years. Due to various reasons, its development has gone through a process of ups and downs. The ups and downs in the development of analog trunking communication have aroused widespread concern in the society. The disadvantages of the analog trunk...
