Abstract
It is disclosed a method to control the traffic generated by packet switched services in digital cellular communication networks. The method, enabled by the operator or by radio resource manager request, exploits network controlled cell reselection procedure and is based on the evaluation of the level of occupation of radio resources and, for every GPRS mobile, on the evaluation of the signal strength received both from the serving cell and from the cells adjacent to the serving one. Suitable cells towards which to move the GPRS mobiles are searched by the procedure. GPRS mobiles are then moved towards a candidate target cell through network controlled cell reselection if the cell supports packet switched service and has an occupation level of radio resources lower than a threshold parameter set by the operator on a cell basis.
