Method, device and system in group system for positioning by short message

Abstract

The invention discloses a method, device and system in a group system for positioning by a short message, relating to the field of data communication. The method comprises the following steps: receiving a positioning request which is transmitted by a requester and comprises an identifying information of a positioning terminal, and storing the identifying information of the positioning terminal; converting the positioning request into a standard short message interface; transmitting the standard short message interface which comprises a positioning verifying code to the positioning terminal which corresponds to an identifier by a short message service center; receiving a short message transmitted by the positioning terminal corresponding to the identifier through the short message service center and the short message which comprises the position message of the positioning terminal to the requester according to the positioning verifying code. The device comprises a first receiving module, a converting module, a first transmitting module, a second receiving module and a second transmitting module. The provided technical scheme can reduce the cost of positioning the terminal in the group system.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a method, device and system for realizing positioning by using short messages in a trunking system. Background technique [0002] The trunking communication system was born in the 1970s. The earliest trunking communication was an analog system. The digital trunking technology emerged around the world in the mid-1990s, and a digital trunking network appeared in China in the late 1990s. Digital trunking system refers to a dedicated mobile communication system in which multiple users share a group of wireless channels and dynamically use these channels. It is a command and dispatch system. Highly demanding enterprises, institutions, industrial and mining, oil fields, farms, public security, police and military departments are in urgent need of this system. The most important feature of the cluster technology is the participation and control of the dispatcher. As the dispatch mana...
