  • Patent number: 5839074
    Abstract: In a process of allocating frequencies to base stations of a mobile radiotelephone network, which process is based on input information containing at least the number of frequencies required for each base station, the frequencies permissible in the mobile radiotelephone network and information on possible disturbance effects among the base stations in the case of identical and/or adjacent frequencies, the following steps are executed alternatingly: (a) selection of a base station from the number of those base stations to which not all contemplated frequencies have yet been allocated, according to a first base station selection criterion and, if necessary, further base station selection criteria, (b) selection of a frequency according to a first frequency selection criterion and, if necessary, further frequency selection criteria, (c) identification of the frequency from (b) as allocated to the base station from (a).
