Method for providing cell location service
First Claim
1. A method for providing cell location service in a digital mobile communication network which provides short message service and comprises a plurality of mobile stations and base stations and a cell location center that is discrete from the plurality of mobile stations and maintains location information on each of said plurality of mobile stations in the digital mobile communication network the method including the steps of:
- (a) generating, at the cell location center a cell location center request message requesting a location of a mobile station and transferring the cell location request message with a short message service for the mobile station;
(b) responsive to the cell location request message, generating, at the mobile station and at predetermined time intervals and transferring a response message having a base station identification representing the base station currently communicating with the mobile station to the cell location center; and
(c) determining a physical location of the mobile station based on the base station identification received from the mobile station.

Abstract
The present invention provides a method for providing cell location service in digital mobile communication network, without additional device for cell location service. The cell location center requests that a mobile station provide current location of the mobile station. Then, the mobile station transfers the base station identification currently communicating with the mobile station. The cell location center finds the location of the mobile station using the base station identification which is uniquely defined in the mobile communication network.
