The embodiment of the invention discloses a method, a device and a system for determining the position of a terminal. The method includes: receiving level database, feature information of each grid by the receiving level database includes the positioning of the region, the characteristic information including geographical information, community information and level information; receiving terminal reported measurement report of MR; the MR in the area of information and level of information and the reception level database in the area of information and level information, and the relative value, absolute value; for each of the grid, according to the absolute value of the values obtained, numerical, the relative value, the value, the absolute value, weight, the relative value, calculate the weight of each of the grid. The numerical representation of the approximate degree of each grid represents the location and position of terminal, the terminal is located in the smallest value In the grid, the geographic information is used to determine the location of the terminal.
