The invention discloses a positioning method. The method comprises the following steps: determining an area to be positioned, and acquiring signal strength data of a signal transmitting device received by a receiving point located in the area to be positioned to obtain a received signal strength data set of the area to be positioned, wherein the receiving point comprises a sampling point and a reference point; acquiring signal strength data of the signal transmitting device received by an object to be positioned to obtain the received signal strength data of the object to be positioned; and comparing the received signal strength data of the object to be positioned with the received signal strength data set of the area to be positioned to obtain location information of the object to be positioned. By adoption of the above technical scheme, high-precision indoor positioning can be realized, since a cellular mobile network can also implement positioning based on RSS, the scheme is applicable to all positioning systems using RSS as position-related measurement values.
