Abstract: A method includes: receiving, by a first RRU, a first reference signal sent by a second RRU, where the first RRU is a to-be-positioned RRU, and the second RRU is an RRU at a known location; determining, by the first RRU, a first delay value based on the first reference signal; and reporting, by the first RRU, the first delay value to an upper-layer network element, so that the upper-layer network element performs location resolving processing based on the first delay value, to obtain location.

Abstract: Embodiments of this application provide a false base station positioning method and a related apparatus, to implement accurate positioning of a false base station. The method includes: A positioning apparatus obtains K pieces of measurement data for a target false base station and location information of user equipments that report the K pieces of measurement data, where each piece of measurement data includes an identifier of the target false base station and a reference signal received power of the target false base station, and K≥2. The positioning apparatus determines location information of the target false base station based on the location information of the user equipment and the reference signal received power of the target false base station.
