The invention relates to a method for determining the total downlink or uplink interference percentage in the coverage area of a designated base station for a mobile radio system with a given channel plan. The invention provides for the need to carry out, after a conventional channel allocation has been carried out, a check of the extent to which total interference requirements are met. The method consists in that field strengths from all base stations are measured on all traffic routes within the geographical area of the mobile radio system. The interference is calculated at each point within the coverage area of a base station for each relevant pair of base stations, preferably base stations which are located in the same channel and base stations which are located in an adjacent channel. The interferences of all the relevant pairs of base stations are added in order to form the total interference at each point. The invention makes it possible to calculate the total interference percentage which constitutes the ratio between the length of road distance with disturbed coverage and the length of total road distance with coverage. The interference percentage is calculated suitably within a contour which limits the coverage area of the base station concerned. |
