  • Method of increasing the number of call options in a mobile telephone system
    Patent number: 4669107
    Abstract: A method of increasing the number of call options in a mobile telephone system with a mobile telephone exchange (MTX) and a number of base radio stations (B1-B8). The method utilizes the overlap existing between the coverage areas (A2,A5), between two base stations, one (A2) with low traffic intensity and the other (A5) with high traffic intensity. A mobile station (MB) in the area (A5) with the higher intensity is controlled such that it communicates via a channel belonging to the base station (B2) for the coverage area (A2) with the lower traffic intensity.
