Problems solved by technology

In daily use, the communication distance between direct terminals is short, and the usage scenarios are limited
The trunking terminal needs the base station to be used together, and the base station also needs to relay wired links for networking. When encountering some emergency situations that require multiple base stations for wired networking, the shorter the time required, the better. It will take a long time for wired lines, which will miss the best time for the rescue command; in the mobile base station, if multiple interconnections are required, satellite networking can only be used. When a large number of private network users need to travel When communicating, this also requires additional relay links and communication costs

example 1

[0045] Example 1: There are 50 vehicles in a convoy driving on the road, the distance between each vehicle is 200m, and the distance between the head and the tail is about 10km. If an ordinary relay base station is installed in the middle of the fleet, since the fleet is mobile, the communication effect for the vehicles at both ends will not be good. If the dynamic wireless networking digital transfer system is used, the vehicle-mounted station is switched to a base station with a repeater mode in the vehicle fleet at intervals of 2km (B), 4km (C), 6km (D), and 8km (E). You can go to F through B, C, D, E. It is guaranteed that A and F can also communicate with high quality. As shown in Figure 6:

example 2

[0046] Example 2: During a certain rescue, the command headquarters and the rescue site are just separated by two mountains. At this time, the two places directly use ordinary walkie-talkies to communicate, which will definitely be blocked by the mountain. The communication effect is not good, which will affect the communication command; if Set up a set of relay base stations on the top of the two mountains and use conventional communication. In this case, a wired network must be used to connect them, and it is not easy to move the equipment to the top of the mountain, which will waste rescue time. If the dynamic wireless networking digital transfer system is used in this case, only two people (B, C) need to take a mobile phone in base station mode and stand on two hills respectively. B receives A, and B then forwards it to C, and C is transferred to D, which can ensure the smooth communication between the command headquarters A and the rescue site D. Such as Figure 7 Shown:...

Abstract

The invention discloses a dynamic wireless networking digital transfer system. The system is composed of transfer wireless networking software and digital mobile terminals, and each digital mobile terminal comprises a digital vehicular-locating set and a digital handset; each digital mobile terminal has a base station mode and a terminal mode and can switch the two modes at will without being re-started; each base station mode terminal not only can dynamically select the adjacent terminal to achieve wireless networking to forward call information, but also can serve as a terminal to call; and the base station mode and the terminal mode both support individual calling, group calling, general calling, point-to-point short messages and point-to-more short messages of an unconfirmed mechanism, specific calling and short message monitoring, current location information reporting and alarming services. The system has the advantages that software and hardware of the terminal mode and the base station mode are integrally designed, a wireless self-networking function is achieved, an additional relay base station and relay link are not needed, and dynamic self-networking communication is efficiently achieved on the basis of existing equipment, so that the communication distance is greatly lengthened.

Description

technical field [0001] The invention relates to command and dispatch in a private network mobile communication system, in particular to a dynamic wireless networking communication system between digital mobile terminals under the situation of no fixed central base station. Background technique [0002] Today, with the rapid development of modern science and technology, digital mobile terminals are increasingly inseparable communication tools in private communication networks, mainly composed of digital vehicle-mounted radios and digital handhelds. In daily use, the communication distance between passthrough terminals is short, and the usage scenarios are limited. The trunking terminal needs the base station to be used together, and the base station also needs to relay wired links for networking. When encountering some emergency situations that require multiple base stations for wired networking, the shorter the time required, the better. It will take a long time for wired l...
