ABSTRACT:
A method of filtering calls between a mobile network provided with frequency channels and mobile telephones registered with this mobile network. When the mobile telephones are located in a control area (N0), the mobile network includes cells (Zi) associated with respective relays (Ri) each transmitting data specific to their associated cell through a beacon channel among one of the frequency channels of the network. The method includes the parametering in neighboring cells of the control area of a frequency channel of the network corresponding to a transmission channel of a transmitter (D) associated with the control area. The transmitter is never connected to the mobile network so as to operate completely autonomously.
