PREAMBLE-BASED POSITIONING METHOD AND DEVICE

摘要

Provided in the present application are a preamble-based positioning method and device. The method comprises: a positioning management network element receives first indication information from a first network device, the first indication information being used to indicate a first random access channel resource; the positioning management network element sends second indication information to a terminal device, the second indication information being used to indicate a second random access channel resource, and the second indication information also being used to instruct the terminal device to send a preamble to the first network device and a second network device; the positioning management network element sends a position information request to the first network device and each second network device; the positioning management network element receives measurement information from the first network device and each second network device, respectively; and the positioning management network element determines the positioning of the terminal device according to the measurement information. By using random access channel resources, the position of a terminal device is measured by a plurality of network devices, and a positioning management network element can accurately position the terminal device according to the measurement information of each network device.
