The invention consist in a simulation method for the resolution of the power control convergence problem. The power to be transmitted by each mobile station and each base station to assure a proper QoS in the system are computed in an iterative way. At each iterative step, the powers to be received are derived from the level of interference received at the previous iterative step by each network element. Once this is done for each network element, the interference levels are then refreshed. The iterations stop when the biggest gap between estimated and observed interfence levels is below a given threshold. Another method of the invention consists in deriving in one step all the power levels to be transmitted by one base station towards many users, assuming a given stable extra-cell interference level. In addition, the invention includes a method for taking the dynamic range of power control in both uplink and downlink, and a method for simulation of power control while in the soft handover. Thanks to the methods described in the invention, the computationnal complexity of the resolution of the power control convergence problem in CDMA cellular network is drastically reduced. Another feature of the invention consists in a reduced complexity when cascading successive static simulations. The invention is thus optimised for dynamic simulations
