Abstract: 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.

Abstract: The method for transfer between systems of different generation includes: modeling with cutting-out of the network into radio cells by distinguishing the frequency bands used, hierachization using coverage data for producing in tables (T) for each frequency band, best/second best server cell data, respectively, representative of an index listing zones corresponding to the best/second best coverage level, determining the zone of radio cells and the source frequency band used in a first system by the terminal, followed by selecting a corresponding starting cell (21, 22) in the tables, generating from the tables a list of candidate cells belonging to a second system and neighbors of the starting cell, selecting in the list at least one arrival cell according to selection criteria.

Abstract: Modelling process designed for deployment of the radio coverage of a cellular radiotelephony network, using a computer system that memorises data representing reference coverage maps of the said network, data representing geographic maps broken down into areas delimited by a contour, called geomarketing data, data representing at least one type of radio station, data representing a sufficient coverage threshold and data representing a coverage threshold of each contour, process initially comprising the following successive steps:
