The simulation system according to the invention memorizes data representative of results of GPRS transfer quality measurements () made on test platform or similar for a variable number of time slots available for GPRS, of at least one quality of service indicator (), of at least one cell configuration () and of traffic volumes for the GSM circuit and GPRS data transfers (). Said system uses this data to simulate () arrivals of GSM circuit calls and GPRS data transfers, and subsequently to calculate a level of GPRS performance achieved for a selected cell configuration (). With the method of the invention it is possible, by dichotomy, to scale the radio interface of a given cell for a given traffic.

Method for scaling the radio interface for GPRS traffic and mixed GPRS and voice GSM traffic

The process for creating, administering and operating distribution maps of the radiocommunications traffic is executed by means of an information system storing data representative of geographical maps cut up into pixels according to the way the network is cut up, and data representative of the traffic in the network. A geographical zone is selected by interactive means between the user and the system and the traffic data corresponding to the zone are recovered and utilized to form at least one distribution map of the circuit traffic. The system calculates the traffic to flow at any point on the map by taking into account progress coefficients as a function of geomarketing data. The system also calculates the capacity of the network for traffic flow at any point. The sub-zones either under-sized or over-sized relative to the traffic can thus be defined.
