Abstract
Provided is a method for sending an in-band positioning signal and in-band positioning system in a communication network. The system includes: a Position Management Station (PMS), arranged to manage one or more Position Service Stations (PSSs) and provide a synchronization reference clock for the one or more PSSs; a positioning center network element, arranged to provide position estimation information for a terminal based on position information of the one or more PSSs and send the position estimation information to the terminal; and the one or more PSSs, of which each PSS uses a same frequency band used by the communication network and is arranged to generate an in-band positioning signal for measuring a distance, regulate a sending clock of the in-band positioning signal according to a difference value between a local sending clock and the synchronization reference clock and send the in-band positioning signal to the terminal.
