Abstract: The present invention provides a positioning information transmission method and communication device. In an embodiment of the present invention, a transmitting end transforms original positioning information into original integer positioning information; then compresses the original integer positioning information into compressed positioning information according to an application precision unit and an original unit of least precision; and afterwards, intercepts lower N bits as simplified positioning information from the number of bits corresponding to the compressed positioning information, wherein the simplified positioning information is a bit distinguishing from positioning information of a receiving end, so that the transmitting end only transmits the simplified positioning information that could be restored to the receiving end.

Abstract: Disclosed are a data pull-up method for dynamically allocating an uplink channel, a communication terminal, and a communication device. The method includes: sending, by a communication device, a pull-up signaling to at least one communication terminal, the pull-up signaling comprising an uplink channel, a time slot, and a pull-up policy allocated by the communication device; receiving, by the communication device, data uploaded by the at least one communication terminal using the uplink channel on the time slot according to the pull-up policy, the data comprising feature information of a subsequent pull-up, and the feature information being used for the communication device to adjust at least one of a subsequent pull-up time and a subsequent pull-up policy. By such means, the present invention improves an activation process flow, can greatly increase channel utilization rate and data pull-up capacity, and improves data pull-up use effects.
