This invention relates to a method of optimising the capacity of at least one WCDMA type mobile telephony network (RT) to create at least one additional service (MBMS) for which the data flow is predominantly in the downlink direction, the method being characterized in that it includes the following steps: creation of at least one planned traffic map (CT) representing the forecast coverage of the network (RT) and the power necessary to use services, for at least one planned deployment date (DD) for the network (RT); calculation of the power available in each cell (CR) in the network (RT) in the absence of emission diversity and then a step of calculation of the power available in each cell (CR) in the network (RT) in the presence of emission diversity; creation of at least one list of cells for which emission diversity has to be installed as a function of at least a number (N) of transmission channels required for the service (MBMS) for which the flow is predominantly in the downlink direction.

The system for automatic planning of delays in a network (N) of SFN type comprises: The module () recalculates the figures of populations located in interference zones for successive combinations of delays, and configuration means () of the system provide the number of permitted iterations. The optimal combination is obtained when said estimated population figures are minimum.

A modeling process for the deployment of the radio coverage of a cellular radiotelephony network, using a computer system that memorizes data representing reference coverage maps of the network, data representing geographic maps broken down into area delimited by a contour, called geomarketing data, data representing at least on type of radio station, data representing a sufficient coverage threshold and data representing a coverage threshold of each contour, the modeling process comprising selecting a geographic map, retrieving geomarketing data and data representing the corresponding reference coverage map, producing a regular grid with a determined spacing showing potential sites representing radio electric stations to be added inside the contour, using calculation functions of the computer and selecting or eliminating potential sites as a function of at least one criterion related to their usefulness.
