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

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

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.

A method for selecting a subset of sites within a set of candidate sites for activating one or more radio stations of a telecommunications network includes building an initial solution of a subset of sites starting from a network configuration having the whole set of active candidate sites; and optimizing the initial solution for activating 'inactive' sites and/or deactivating 'active' sites, in order to minimize a predetermined cost function for the solution. The steps of building and optimizing the initial solution are adapted to define both solutions that have a geographic coverage area that is greater than a predefined minimum coverage area and to manage an amount of traffic that is greater than a predefined minimum expected traffic value. A processing system and a processing program or group of programs can be executed by the system when pre-arranged for performing the above method.

Radio station site in a telecommunications network

A method for assessing the characteristics obtainable in a network for mobile telecommunications apparatuses suitable for managing calls with both data traffic and/or voice and data traffic. On the basis of the performance requested for the quantity and characteristics of the traffic required, the method provides a simple manner for determining both the effective performance of the network in terms of the probability of occupation of the radio channels and the probability of dropped calls during the peak traffic period and optimal dimensioning of the network.

Method for dimensioning a mobile telecommunications network

A method of assessing traffic and performance characteristics of a mobile telecommunications network in terms of the level of service has inputs as to performance requirements for voice traffic and voice loss, data traffic or data loss, information with respect to the voice traffic offered and the data traffic offered and average length of an individual message. The determination is made on the basis of the number of radio slots which are allocable to data traffic and on the basis of an exponential distribution of the average call waiting time in the queue.
