Abstract
A process for managing intercellular transfers of communication in a cellular radio communication system. A specified number of microcells inside umbrella cells each respectively possess a base station for allowing the routing of the communications. Radio direction finding is used to pinpoint at least two successive virtual positions of the mobile stations in communication in relation to the base station of the umbrella cell in order to deduce therefrom a speed of movement of each mobile station in the time interval which separates the pinpointing of their positions. The speeds of movement which are obtained are compared to the specified speed values so as to entrust the management of the communication from a mobile station to the base station of the umbrella cell in which it lies when its speed is greater than the specified speed value, or to the base station of the microcells when it is not greater than the specified speed value.
