Position determination based on the area of ​​the terminals in the wireless network

摘要

Technique to estimate the position of the wireless terminal. In the method, a number of transmitters that are used to estimate the position (for example, BTS) to be received first identification. Next, I determine the expected area of ​​these transmitters. When the signal from the transmitter is received by the terminal, the expected area is associated with each transmitter, shows an area potential terminal is located is high. Each expected area, (eg, the center of the expected area) and the position is used as the estimated position of the terminal (or error estimate) and the uncertainty is related to the estimated position. (For example, on the basis of the weighted average) was synthesized, the expected area of ​​the transmitter, it is determined synthesis expected area, is given as an estimate of the location of the terminal.
