Abstract
Abstract The present invention relates to determining the geographic location of a mobile station in a mobile communications system. The object of the invention is to protect the integrity of the user of the mobile station, so as to prevent the location of the mobile station being established by an outsider against the will of the user. In this respect, an authorization check is carried out in conjunction with a request for determination of the geographical location of a mobile station. The geographical location is only determined when authorization is found for the mobile station to be located. This authorization control involves checking that the user of the mobile station has granted permission for the location of his mobile station MS to be determined on the part of an outsider. The authority check may also include the condition that only certain outsiders may be informed of the geographical location of the mobile station.
