Communication system and corresponding method, computer program, and storage means

摘要

The invention relates to a communication system comprising communication nodes communicating via multi-frequency, time division multiple access frames. The nodes form a hierarchical cellular radio network that defines hierarchical levels which each include a base and at least one handset. The communication nodes are enabled to communicate via the base of the hierarchical level thereof. A master node comprises: a means (4.2) for selecting, in each of the frames, a transmission resource that is common to said communication nodes; a means (4.3) for broadcasting to the communication nodes, through the hierarchical levels via the respective bases thereof, information representative of the selected common transmission resource. The system is suitable for enabling said communication nodes to broadcast messages via the selected common transmission resource.
