Positioning method and apparatus
First Claim
1. A positioning method, wherein the method comprises:
- determining, by a positioning server having a transceiver, positioning signal configuration information;
sending, by the transceiver of the positioning server, the positioning signal configuration information to a positioning signal sending entity;
obtaining, by the positioning server, a measurement estimation result of a shortest transmission path among a plurality of transmission paths between a positioning signal measurement entity and the positioning signal sending entity by comparing a first path of the plurality of transmission paths to a second path of the plurality of transmission paths; and
positioning, by the positioning server, one of the positioning signal measurement entity and the positioning signal sending entity by using the measurement estimation result of the shortest transmission path, wherein one of the positioning signal measurement entity and the positioning signal sending entity is a terminal.

Abstract
Embodiments of the present invention provide a positioning method, including: determining, by a positioning server, positioning signal configuration information; sending, by the positioning server, the positioning signal configuration information to a positioning signal sending entity; obtaining, by the positioning server, a measurement estimation result of a shortest transmission path between a positioning signal measurement entity and the positioning signal sending entity; and positioning, by the positioning server, a terminal by using the measurement estimation result of the shortest transmission path, where the terminal is one of the positioning signal measurement entity and the positioning signal sending entity. The embodiments of the present invention can resist an NLOS path deviation and a positioning signal strength loss and an SINR loss, so as to improve the positioning accuracy.
