The invention provides a positioning information transmission method and a communication device, which can improve transmission efficiency of a wireless communication system. In the embodiment of the invention, the method comprises the following steps that: a transmitting end transforms initial positioning information into initial integer positioning information; the transmitting end compresses the initial integer positioning information into compressed positioning information according to an application accuracy unit and an original minimum accuracy unit; then, the transmitting end intercepts low N digits as simplified positioning information from a binary numerical value corresponding to the compressed positioning information, the simplified positioning information is a difference digit with the own positioning information of a receiving end, so that the transmitting end only needs to transmit the simplified positioning information to the receiving end, and then the receiving end can revert the initial positioning information of the transmitting end. Thus, under the premise of guaranteeing that the receiving end can obtaining effective position information of the transmitting end, storage space of wireless communication data occupied by the transmitting end while transmitting the compressed position information is reduced, and transmission efficiency of the wireless communication system is improved.
Description
[0001] This application claims the priority of the Chinese patent application with the application number 201510413603.9 and the title of the invention "a method and communication device for positioning information transmission" submitted to the China Patent Office on July 14, 2015, the entire contents of which are incorporated by reference In this application. technical field [0002] The present invention relates to the technical field of communication, in particular to a method for transmitting positioning information and a communication device. Background technique [0003] In the current Digital Mobile Radio (DMR) standard, global positioning information is defined in a standard National Marine Electronics Association (NEMA, National Marine Electronics Association) format, and the data is transmitted through a UDT transmission mechanism. [0004] In the prior art, the global positioning information in the DMR standard needs to be transmitted with 2 time slot frames, inc...
