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

Method for scaling the radio interface for GPRS traffic and mixed GPRS+voice GSM traffic, using a test platform comprising at least one cell model of a mobile radiotelephone network and a traffic simulation system memorizing at least one quality of service indicator, at least one cell configuration and traffic volumes for voice GSM and GPRS data transfers, this method being characterized in that:

• measurements representative of GPRS quality of service are performed on test platform, these measurements being made for different volumes of GPRS traffic in said cell model and in relation to the number of time slots available for GPRS traffic,
• said traffic simulation system stores in memory data representative of measurements made on test platform, this data forming quality parameters,
• for at least one cell configuration and for determined volumes of GSM traffic and GPRS data transfers, a plurality of sessions is generated by said traffic simulation system, forming arrivals of GSM calls and GPRS data transfers, and said simulation system, taking said quality parameters into account, calculates a level of GPRS performance achieved for said cell configuration.
• by dichotomy, said configuration of cell model is modified by addition/removal of at least one new time slot available for GPRS traffic or of a transceiver, in order to determine the minimum configuration enabling said level of performance to attain a determined threshold.
