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 for configuring a cellular network comprising a plurality of network cells. The method comprises:



monitoring, during a monitoring time period, a performance indicator of each network cell for each one of a plurality of monitoring time intervals of said monitoring time period;
determining a plurality of sets of measured signal levels, wherein each set of measured signal levels is associated with a respective territorial portion of a geographic area covered by the cellular network, and wherein each measured signal level of each set of measured signal levels is associated with a respective measured network cell, among the plurality of network cells, at least partially within that territorial portion, with a respective cell configuration of said measured network cell, and with a respective monitoring time interval;
determining, for each measured network cell, a simulated signal level being indicative of an expected signal level for that measured network cell in the respective cell configuration;
determining, for each measured network cell and for each monitoring time interval, a signal level deviation as a difference between the respective measured signal level and the respective simulated signal level;
for a reference network configuration (RNC1) including, for each measured network cell, a respective reference cell configuration taken by that measured network cell after the monitoring time period:
(i) determining, for each measured network cell, a reference simulated signal level indicative of an expected signal level for that measured network cell in the reference cell configuration;
(ii) updating, for each monitoring time interval, each measured signal level according to the respective simulated signal level and to the respective signal level deviation;
(iii) determining, for each measured network cell and for each monitoring time interval, an estimated performance indicator based on the respective performance indicator, on a number of sets of measured signal levels having at least one measured signal level associated with said measured network cell, and on the respective updated measured signal level, and
configuring the cellular network according to the estimated performance indicators determined for the measured network cells.

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.
