Abstract: A method for controlling communications in a communications system includes operating a client device in the communications system; communicating by a first master device with the at least one client device; and executing a communication management service in the first master device for controlling communications between the first master device and the at least one client device. The communication management service instructs the first master device to transmit identification information of the first master device for reception by the at least one client device to inform the at least one client device the identity of the first master device. A server, a client for the system, and a computer program product are also included The master device may also manage bandwidth provided to the client devices. The bandwidth management may take into account the priority of messages from client devices, the overall bandwidth available at the region, etc.
