The invention relates to a mobile subscriber location calculating method based on neighboring region base station RSRP (Reference Signal Receiving Power) information, belonging to the field of calculating location information of mobile subscribers under coverage of base stations. The mobile subscriber location calculating method based on neighboring region base station RSRP information includes the steps: accessing the data saved in base stations through a telecom operator, screening the data type related with calculation of the subscriber location, establishing a path loss model to correlatethe distance between different neighboring region base stations and subscribers with the pass loss, by means of the frequency range, the bandwidth, the antenna gain, the cell power, the antenna height, the reference signal power and other information, calculating the path loss so as to obtain the distance between the neighboring region base stations and the subscribers, and finally obtaining the location of the subscribers by obtaining the latitude and longitude information of the subscribers through triangulation location. Modeling of the mobile subscriber location calculating method based onneighboring region base station RSRP information fully utilizes the rich base station data in the cellular network, and can provide subscriber location information for related departments and providereliable support.
