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. Therefore, the storage space of wireless communication data occupied by the compressed positioning information transmitted by the transmitting end can be reduced while ensuring the receiving end can obtain the valid positioning information of the transmitting end.

Positioning information transmission method and communication device

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.
