POSITIONING METHOD, APPARATUS, AND SYSTEM

摘要

Embodiments of the present invention relate to the field of communications, and provide a positioning method, apparatus, and system, so as to improve positioning precision. The method includes: determining, by a server, a positioning measurement parameter, and generating measurement configuration information carrying the positioning measurement parameter, where the positioning measurement parameter is a parameter that the server requests a terminal to measure and is used to position the terminal; sending, by the server, the measurement configuration information to the terminal through a base station; receiving, by the server through the base station, configuration response information returned by the terminal, where the configuration response information carries a positioning response parameter, and the positioning response parameter is a measurement result generated after the terminal measures the positioning measurement parameter; and positioning, by the server, the terminal according to the positioning response parameter carried in the configuration response information.

1. A server, comprising:
a processing unit, configured to determine a positioning measurement parameter, generate measurement configuration information carrying the positioning measurement parameter, and send the measurement configuration information to a terminal through a sending unit, wherein the positioning measurement parameter is a parameter that the server requests the terminal to measure and is used to position the terminal, and the positioning measurement parameter comprises at least one of the following parameters or parameter combinations: a precoding matrix indicator (PMI)/rank indicator (RI) characteristic and the number of multiple paths of the terminal, a handover failure rate measured by the terminal, a radio link failure rate measured by the terminal, a signal to interference plus noise ratio of the terminal, and the number of cells from which the terminal receives strong interference; the sending unit, configured to send the measurement configuration information generated by the processing unit to the terminal through a base station; and a receiving unit, configured to receive, through the base station, configuration response information returned by the terminal, wherein the configuration response information carries a positioning response parameter, and the positioning response parameter is a measurement result generated after the terminal measures the positioning measurement parameter, wherein the processing unit is further configured to position the terminal according to the positioning response parameter carried in the configuration response information received by the receiving unit.
