Abstract: A method of evaluating the performance of a mobile telephone network having at least a first and a second simulation of a first and a second network configuration, respectively, which are statistically independent of each other. Each simulation includes the following steps: specifying a total number of users to be simulated; determining a sequence of activation of user blocks included in this total number of users to be simulated and indicating a traffic distribution; activating said user blocks in succession until the total number of users to be simulated is reached; and processing at least one radio resource management event relating to the traffic distribution associated with each currently activated user block. The simulations are repeated until a predetermined accuracy threshold is reached for each simulated network value.

Abstract: 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.

Abstract: A method for assigning scrambling codes in a code division multiple access cellular radio communications network includes a plurality of network cells covering a geographic area, including: determining, for each of the cells, a respective set of adjacent cells by: taking a first set of cells that are neighbors of the given cell; taking a second set of cells that are neighbors of neighbors of the given cell; taking a third set of cells that are neighbors of neighbors of neighbors of the given cell, wherein two cells are considered neighbors in case the respective coverage areas at least partially overlap; taking a fourth set of cells which, in at least one point of the best server are of the given cell, have an adjacent coefficient with the given cell higher than a predetermined threshold; combining the first, second, third and fourth set of cells; and assigning to each cell of the set of adjacent cells a scrambling code different from a scrambling code assigned to the given cell.

Abstract: An antenna site equipped with reconfigurable antennas in a communication network and having capacity to serve communication traffic in a respective area of competence is configured by partitioning the area the area of competence into a set of cells. The number of cells in the set is optimized by ensuring that the traffic is evenly distributed among the cells. This result is preferably achieved starting from a reference set of cells by locating: —i) areas of superposition between adjacent cells covered jointly by traffic capacity of adjacent cells in the reference set of cells, and—ii) uncovered areas between adjacent cells, that is, areas not covered by traffic capacity of any cells in the reference set of cells. The areas of superposition are removed and the traffic capacity thus made available is assigned to the uncovered areas. If any uncovered areas remain, the number of cells in the reference set of cells is increased and the process repeated.

Abstract: 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.

Abstract: A mobile-radio network includes radio base stations providing radio coverage to the users of the network via antenna elements, wherein the antenna elements are equipped with at least one first communication channel and at least one second communication channel. The first communication channel provides a first layer of individual microcell radio coverage for the antenna elements. The second communication channel is made common to groups of the antenna elements and provides a second layer of virtual macrocell radio coverage, wherein the coverage of each virtual macrocell aggregates the microcell radio coverages of the antenna elements included in the respective group.
