The invention relates to a method and arrangement for redetermining the operating frequencies of base stations of the internal network when the operating frequency of base stations of the external network has been changed. According to this new solution, the redetermination of the operating frequencies is carried out on the basis of a frequency measurement performed for an earlier determination and information of base stations, in which the operating frequencies have been changed. Of the information of a frequency plan containing the operating frequencies of the base stations of the external network it is concluded whether the frequency being used by the internal network has remained interference-free or the frequency should be changed. In addition, the redetermined operating frequencies are checked by a signal strength and C/I measurement and arranged in an order of suitability, when required. |
