A method of assigning radio frequencies to base stations (-) of a first radio telecommunications network operating in a first radio frequency band and co-existing with at least a second radio telecommunications network (--) 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 (-) of the first radio telecommunications network frequencies in accordance with the radio frequency assignment plan selected.

Method of planning of mobile telecommunications networks

A method of upgrading a wireless mobile communications network deployed in the field, including capturing network events from the wireless mobile communications network; obtaining network simulation data from an automated network simulation planning tool; combining the captured network events and the network simulation data to derive diagnostic indicators adapted to evidence criticalities in a current network configuration; and modifying the current network configuration to overcome the criticalities.

Method and system for optimizing the configuration of a wireless mobile communications network

The radiation diagram of an antenna for serving a cell in a cellular communication network is selected from a plurality of available radiation diagrams by: classifying the plurality of available radiation diagrams in terms of a related radiation gain value; identifying for each one of the sectors a plurality of variations of the radiation gain value associated with the available radiation diagrams; estimating for each sector an initial value of at least one indicator of network operative functionality; estimating for each sector at least a desiderate value of variation of the related radiation gain value; and selecting at least one configuration that approximates the variation of the radiation gain value involving the desiderate value.

A method of dimensioning a data packets handler apparatus in a mobile communications network includes a plurality of cells, each one providing mobile communications coverage in a respective geographic area, the mobile communications network supporting packet-switched traffic and circuit-switched traffic, wherein the data packets handler apparatus to be dimensioned is associated with at least one cell of the mobile communications network. The method includes: obtaining an indication of radio communications resources of the at least one cell; obtaining an indication of an offered packet-switched traffic with respect to the at least one cell; and determining an amount of resources of the data packets handler apparatus potentially needed by the at least one cell for handling the packet-switched traffic based on the radio communications resources and on the offered packet-switched traffic.
