Method and system for detecting a location of a mobile communication terminal

摘要

A system and method for detecting a location of a mobile communication terminal. A mobile communication network for communication with the terminal and a cell identifier (ID) of a base station is set. A public land mobile network (PLMN) ID of the network and the cell ID are stored. One or more networks other than the set network are searched for. When the one or more other networks are searched for, the searched one or more other networks are sequentially set. Cell information according to the one or more other networks is searched for. Cell IDs of base stations communicable with the terminal are set. PLMN IDs of the one or more other networks and the cell IDs are stored. A common area between cells set using the stored PLMN and cell IDs is determined. Information about the common area is detected as location information of the terminal.

1. A method for detecting a location of a mobile communication terminal, comprising:
setting a mobile communication network for communication with the mobile communication terminal and a cell identifier (ID) of a base station and storing a public land mobile network (PLMN) ID of the mobile communication network and the cell ID; searching for one or more mobile communication networks other than the set mobile communication network; sequentially setting, when the one or more other mobile communication networks are searched for, the searched one or more other mobile communication networks, searching for cell information according to the set one or more other mobile communication networks, setting cell IDs of base stations communicable with the mobile communication terminal, and storing PLMN IDs of the set one or more other mobile communication networks and the set cell IDs; and determining a common area between areas of a plurality of cells set using the stored PLMN ID and cell IDs and detecting information about the common area as location information of the mobile communication terminal.
