[0011] It can be seen from the above that each time a terminal reports GPS positioning information, it takes 4 frames (240 milliseconds) in total. Therefore, each channel can only support up to 4 terminals reporting GPS positioning information per second, which is difficult to meet the large capacity of public security users. The need for rapid reporting of location information

Embodiment Construction
[0041] In order to fully understand the technical content of the present invention, specific embodiments are given below, and the technical solutions of the present invention are introduced and explained in detail in conjunction with the accompanying drawings. For the convenience of description, in the following specific embodiments, the PDT digital trunking communication system is adopted, and the position information of the terminals is GPS positioning information for introduction.
[0042] Such as figure 1 As shown, the PDT digital trunking communication system includes two parts: terminals and system facilities. The terminals are mainly mobile stations such as mobile stations and vehicle stations; the system facilities are composed of base station subsystem, switching subsystem, network management subsystem, dispatching subsystem, and GIS dispatching subsystem. System and other components, in which switching, network management, dispatching subsystems, and GIS dispatching ...

The invention provides a method for quickly reporting position information of terminals in a digital cluster communication system. The method comprises the following steps of (1) enabling a base station to distribute a dynamic number to each terminal which is currently registered in the base station, and establishing a mapping table between the dynamic number of each terminal and the standard terminal address of the terminal; (2) enabling each terminal to form a single signaling frame corresponding to the self dynamic number, wherein the single signaling frame contains the position information of the terminal; (3) enabling the terminal to report the single signaling frame containing the position information of the terminal; and (4) according to the mapping table between the dynamic number of the terminal and the standard terminal address, enabling the base station to replace the reported dynamic number of the terminal with the standard terminal address, and send the standard terminal address and the corresponding position information of the terminal to a control center. Compared with the prior art, the position information is reported by a multiframe signal, and a single-frame signal is adopted to report the position information, so the working efficiency is obviously improved.
Description
technical field [0001] The invention relates to the technical field of digital trunking communication, in particular to a method for quickly reporting the location of a terminal in a digital trunking communication system. Background technique [0002] Mobile communication systems can be divided into public mobile communication systems and private mobile communication systems according to their nature of use. The trunking communication system belongs to a dedicated mobile communication system, which is a multi-purpose, high-efficiency wireless dispatching communication system that shares resources, shares costs, and shares channel equipment and services. In terms of network topology, the trunking communication system has a structure similar to that of the public mobile communication system: the terminal communicates with the base station through the air interface; each base station is connected to a control center composed of different subsystems such as switching functions, ...
