Claim of US Patent No. 10,142,958

1. A method of determining location information based on cell information, the method comprising:receiving, using at least one processor, cell information related to a base station servicing at least one mobile terminal;
determining, using the at least one processor, approximate location information based on the cell information using a location information database configured to store location information associated with a plurality of cell information, the stored location information including a plurality of location information gradation levels, the plurality of location information gradation levels including a state gradation level, a city gradation level, a neighborhood gradation level, a street gradation level, and a city block gradation level;
determining, using the at least one processor, a desired gradation level from the plurality of location information gradation levels associated with a location-based service;
extracting, using the at least one processor, the approximate location information corresponding to the desired gradation level associated with the location-based service from the location information database and the determined approximate location information; and
transmitting, using the at least one processor, the location-based service to the at least one mobile terminal based on the extracted approximate location information,
wherein the determining the approximate location information based on the cell information includes,
determining at least one neighboring base station adjacent to the base station servicing the at least one mobile terminal based on the cell information,
estimating a location of the base station servicing the at least one mobile terminal based on cell identifier information of the at least one neighboring base station,
calculating a centroid value of a cell covered by the base station servicing the at least one mobile terminal based on a cell shape corresponding to the estimated location of the base station, and
determining location information corresponding to the centroid value of the cell as location information of the at least one mobile terminal.
