Method for controlling a communications channel shared by several stations
First Claim
1. A method for controlling a channel shared by several transmitting/receiving stations, comprising at least one phase of use of the channel by a station participating in a communication, in the course of which said station transmits traffic information on the channel, followed immediately by a phase of retention of the channel by said station, in the course of which said station transmits signaling information indicating to each other station participating in the communication that it is authorized to transmit in turn traffic information on the channel, the phase of retention of the channel by said station continuing, so long as the communication is in progress, until another phase of use of the channel by a station participating in the communication.

Abstract
During a communication, a channel is shared by several transmitting/receiving stations comprising a single master station and one or more slave stations. A station becomes a master station by transmitting traffic information on the channel. After the master station has stopped transmitting traffic information without the communication being concluded, it continues to transmit signaling information authorizing each slave station in turn to transmit traffic information on the channel. This transmission of signaling information continues for as long as the communication lasts, until one of the slave stations becomes the master station in turn by beginning to transmit traffic information on the channel or until the same station begins to transmit traffic information again, hereby remaining the master station.

8. A station for transmitting/receiving on a shared channel, comprising:
-
means of use of the channel in master mode in the course of a communication, which are designed to transmit traffic information on the channel; means of retention of the channel in master mode in the course of a communication, which are designed to alternately transmit signaling information on the channel and to listen to the channel, said signaling information authorizing each other station participating in the communication to transmit in turn traffic information on the channel; means of reception in slave mode for receiving traffic and signaling information transmitted in master mode by another station participating in the communication; and means of control for activating the means of use of the channel in master mode in response to a request for use when signaling information authorizing the transmission of traffic information has been received by the means of reception in slave mode, so as to activate the means of retention of the channel in master mode in response to a deactivation of the means of use of the channel in master mode, and to activate the means of reception in slave mode in response to the reception of signals originating from another station participating in the communication by the means of retention of the channel in master mode listening to the channel. - View Dependent Claims (9, 10, 11, 12, 13, 14)
