Abstract
A process for locating mobile stations in a cellular mobile radio network with several spatially distributed fixed base stations associated each to several cells and several mobile stations. The network has storage devices which contain information about the identify of the mobile stations and about the cells in which the individual mobile stations were last signaled. In order to locate a mobile station in as flexible as possible a manner, but also if required as precisely as possible, the information in the storage devices is used for approximately locating the searched-for mobile station and at least one direction finding is carried out in order to more precisely locate the mobile station. A cellular mobile radio network for carrying out this process is characterized in that the individual stations are each in communication with a direction finder and that the mobile radio network has a locating central office in communication with all direction finders.
