Patent ID: 7228135

Claim:
A method for cellular communications, characterized in that: a file in electronic form with fragments of a digital geographical map of the vicinity is preliminary introduced into a control center of a cellular communications system, the map comprising coordinates and characteristics of base stations arranged in cells and geographical coordinates of the borders of the cells, wherein in the process of radio communications, data on the location of a corresponding mobile station for communication therewith are determined with the aid of a receiver of a satellite location determination system, which receiver is built in a mobile station, and are transmitted through a base station to the control center of the cellular communications system, and the file of a fragment of the digital geographical map is transmitted from the control center of the cellular communications systems through a corresponding base station to a mobile station, the map comprising coordinates and characteristics of the base station of that cell where this mobile station is, coordinates and characteristics of the base station of neighboring cells with coordinates of their borders; and then, in the mobile station, a comparison of current data of its location and the coordinates of cell borders is carried out at least one of when there is a transition of the mobile station to another cell—“handover”—or when there is a transition from one cellular communications network to another—roaming—data on completion of the “handover” or conduction of the roaming and changes of the working parameters of communications channels and produced in the mobile station and transmitted to a corresponding control center of the cellular communications systems, characterized in that the dimension of the fragment of the geographical map transmitted to the mobile station and the periodicity of transmission of data on its location by that mobile station to the control center of the cellular communications system are changed depending on the speed of movement of the mobile station.
