DIGITAL TRUNKING SYSTEM TERMINAL AND METHOD FOR REPORTING GPS POSITIONING INFORMATION THEREOF

摘要

The present invention provides a digital trunking system terminal and a method for reporting global positioning system (GPS) positioning information thereof, so as to implement GPS positioning information reporting of the terminal. The method comprises: at a time point indicated by a back-reporting policy in a positioning information back-reporting request obtained from short data burst (SDB) signaling sent by a system side, a terminal constructing its own GPS positioning information into the SDB signaling and reporting the SDB signaling to the system side. The terminal comprises: a receiving module, used for receiving SDB signaling sent by a system side and saving a back-reporting policy related parameter carried therein; a GPS module, used for collecting its own GPS positioning information at a time point indicated by a back-reporting policy; and a reporting module, used for constructing the collected GPS positioning information into the SDB signaling and sending a positioning response message to the system side in an SDB signaling manner. With the method and the terminal of the present invention, a terminal in any state may receive a back-reporting request delivered by a system, and report its own location information to the system side.
