Method for laying out the infrastructure of a cellular communications network
First Claim
1. A method for planning cells of a radio cellular communication network, each cell comprising a base station for controlling a plurality of mobile units in a geographical cover zone covered by said station, handover selection to manage changes of base station controlling a mobile unit when said mobile unit passes to the cover zone of a neighboring cell, said method comprising, the each of said cells, the steps of:
- assuming a geographical location and technical characteristics for the base station of said cell;
estimating a radio-electric cover of said base station;
determining a real geographical cover zone of said base station, comprising the steps of;
simulating movements of mobile units in said cell;
determining places of transfer of said mobile units to a neighboring cell, from said handover selection, as a function of said simulated movements; and
obtaining a real geographical cover zone of said cell, by modifying said radio-electric cover taking into account said places of transfer; and
affecting transmission resources to said cell as a function of said real geographical cover zone.

Abstract
A method for the laying out of the infrastructure of a cellular communications network, notably with mobile units, the network being of the type constituted by a plurality of broadcasting transmitters, each broadcasting on its own broadcasting cell, at least certain of the cells being adjacent and having common overlapping zones, a system of management of the network assigning a single broadcasting cell to a given mobile unit at a given time, according to a given broadcasting transmitter assigning method, the method for the laying out consisting in determining the geographical location and the technical characteristics of each of the transmitters of the network in taking account of the conditions of entry/exit and of movement of the mobile units in the overlapping zones. Thus, the coverage of the network is determined dynamically, such as it is seen by the mobile units.
