Determining location information in cellular network
First Claim
1. A method for determining cell-specific location information to be used in a mobile communication network, the method comprising encrypting the cell-specific location information on at least one cell of the mobile communication network to be used in the particular mobile communication network by using a predetermined encryption algorithm, determining substantially the geographical coverage area of the cell, and storing the encrypted, cell-specific location information and the geographical coverage area information on the cell in a database such that the two aspects of the information are interlinked.

Abstract
A method for determining cell-specific location information, wherein the cell-specific location information to be used in a mobile communication network is encrypted using a predetermined encryption algorithm. The geographical coverage area corresponding with a particular cell is determined and the cell-specific location information and the geographical coverage area information are stored in a database and interlinked. A cell positioning service request is transmitted from a mobile station to a service provider, the cell positioning service request including the encrypted, cell-specific location information on the mobile station and, in response to the request, the service provider retrieves from the database the geographical coverage area information corresponding with the encrypted, cell-specific location information on the mobile station in the request, and transmits a cell positioning service message to the mobile station, the cell positioning service message including at least the geographical coverage area information.
