Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] The present invention is a group positioning method based on position measurement samples in a mobile communication network on the network side: first, the mobile terminal to be tested sends a pilot signal to the base station, and the base station obtains the measurement information of the mobile terminal from the received signal ( For example, the signal arrival time TOA (Time Of Arrival) and signal received power W) can be obtained in the GSM network, and the measurement data vector is composed of these two measurement data and the plane coordinates (x, y) of the position of the mobile terminal to be measured (TOA, W, (x, y)); each base station calculates the positioning of each mobile terminal according to the received measurement data vec...
