Method for transmitting locating information by cluster communication system by the aid of idle traffic channels

Abstract

Disclosed is a method for transmitting locating information by a cluster communication system by the aid of idle traffic channels. The method is used for configuring a mobile terminal which can support short data teleservices in a standard cluster communication system which can achieve short data calling. The method comprises that the mobile terminal packages the locating information in the short data after receiving the locating information, and sends transmitting requests with specific identifications to the system; the cluster system queries whether idle traffic channels are available or not in traffic channel lists after receiving the requests, and instructs the mobile terminal by control instructions to transmit the locating information through the idle traffic channels if the idle traffic channels are available; the idle traffic channels receive calling request instructions which are sent by the mobile terminal, judge whether the calling request instructions are transmitting the locating information or not, accept and process the instructions if the instructions are sending the locating information, and transmit the analytic locating information to a scheduling system or a locating system of the system; and the idle traffic channels discard and do not process the instructions if the instructions are not sending the locating information. The utilization efficiency of system traffic channels is improved by means of utilization of the idle traffic channels in the present cluster communication system.

Description

Technical field [0001] The invention belongs to the field of communication and is mainly applied to professional communication systems, and particularly relates to a method for a trunked communication system to transmit short data using idle service channels. Background technique [0002] The trunking communication system is a dedicated dispatching mobile communication system that shares wireless channels. It adopts the multi-channel sharing and dynamic channel allocation technology in modern communication. It has dispatch functions such as individual call, group call and broadcast call. Its characteristic is calling The establishment is fast, users have different priorities, call time is limited, and it has remote kill and resurrection functions, which is very suitable for public security, military, forestry and other departments. [0003] Short data service is the main data service in the cluster system. Using short data services, many data services can be expanded, such as GPS / ...
