Abstract: A method of assigning radio frequencies to base stations (105-1) of a first radio telecommunications network operating in a first radio frequency band and co-existing with at least a second radio telecommunications network (110, 110-1;115, 115-1) operating in a second radio frequency band at least partially overlapping the first radio frequency band. The method comprises: simulations of electromagnetic field propagation; defining a cost function for quantitatively evaluating a radio frequency assignment plan for the base stations of the first radio telecommunications network; calculating an initial radio frequencies assignment plan for the base stations of the first radio telecommunications network; calculating at least one alternative radio frequency assignment plan starting from the initial radio frequency assignment plan; selecting as radio frequency assignment plan for the base stations of the first radio telecommunications network one of the alternative radio frequency assignment plans based on the values of the cost function, and assigning to the base stations (105-1) of the first radio telecommunications network frequencies in accordance with the radio frequency assignment plan selected.

Abstract: A method (200; 600) of balancing a traffic load among at least apart of traffic managing entities (105;110) of a mobile telecommunication network (100) comprising a plurality of traffic managing entities (105;110) is proposed. The method comprises the following steps: collecting (205; 605) traffic-related data referred to said at least a part of traffic managing entities (105;110); identifying (220; 620) a first set of traffic managing entities (105;110) managing an excessive traffic load on the basis of such traffic-related data; identifying (220; 620) a second set of traffic managing entities (105;110) adapted to take charge of at least part of the excessive traffic load to which traffic managing entities (105;110) of first set of traffic managing entities (105;110) are subjected. Moreover, for each traffic managing entity (105;110) of the first set of traffic managing entities (105;110) the method comprises: determining (235-240; 630) at least one traffic managing entity (105;110) of the second set of traffic managing entities (105;110) adapted to take charge of at least part of the excessive traffic load managed by said traffic managing entity (105;110) of the first set of traffic managing entities (105;110); assigning (245; 635) at least part of the excessive traffic load to which said traffic managing entity (105;110) of first set of traffic managing entities (105; 10) is subjected to the determined at least one least one traffic managing entity (105;110) of the second set of traffic managing entities (105;110), and adjusting (245; 635) radio communication parameters of said traffic managing entity (105;110) of the first set of traffic managing entities (105; 10) and of said determined at least one traffic managing entity (105;110) of the second set of 20 traffic managing entities (105;110) thereby redistributing traffic load on the basis of such assigning.
