Problems solved by technology

In emergency rescue and disaster relief and emergency rescue, especially in maritime search and rescue, the rescue location is usually beyond the coverage of the trunking system. However, the existing wireless trunking communication system usually does not have a dynamic networking function, and its coverage is limited by the base station, resulting in the command and dispatch function. loss, resulting in a huge loss
[0005] In summary, the existing wireless trunking communication system obviously has inconvenience and defects in actual use, so it is necessary to improve it

Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] Such as figure 1 As shown, the present invention is a digital trunking communication system 100 for private network communication, and the private network is used for digital walkie-talkie, vehicle station or ship station. The system includes a terminal 10, a base station 20, a network subsystem 30, and a dispatch center 40. The base station 20 is connected to the terminal 10 through an air interface to complete the access functions of trunking services, data services and telephone services.

[0028] The working state of the terminal 10 includes a transit state and a terminal state, and in ...

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...
