Abstract:
1. A method for communication traffic load balancing between cells of a communication system which are differently loaded comprising the following steps: a) determining an evaluation factor by a predefined mapping function for a home cell k and for at least one other cell l, the evaluation factor being a measure of the load on the respective cells, b) determining at least one comparing factor with respect to said home cell evaluation factor by calculating the difference between the evaluation factor of the home cell and at least one other cell, c) assigning each of said comparing factors to corresponding traffic load penalty factors, the traffic load penalty factors being a measure of load difference and/or transmission quality between the cells k and l, wherein the assignment is repeated in a loop comprising the steps a) to b) and wherein current traffic load penalty factors are determined depending on predefined traffic load penalty factors and/or forerunner traffic load penalty factors determined in earlier cycles of the loop, and d) evaluating on the basis of the current traffic load penalty factors, unused transmission capacity of a cell and/or cells in comparison to the home cell and/or a time at which at least a part of the traffic of the home cell is handed over to at least one cell with unused capacity.
