Abstract: A transmission regulation method which may be performed by a station having at least one data frame for transmitting over a telecommunications network is disclosed. In one aspect, the method comprises, during at least one selection round from a set of selection rounds, obtaining a value representative either of an authorization to transmit or a prohibition to transmit the frame. Furthermore, when the value is representative of an authorization to transmit, transmitting an information signal over a first communications channel of the network, to inform the other stations that the station has obtained a value representative of an authorization to transmit; or when the value is representative of a prohibition to transmit, listening for an information signal, if any, transmitted over the first communications channel of the network. The method listens to or transmits over a second communications channel of the network that is different from the first communications channel.

Abstract: A method is provided for regulating transmission implemented by a station, having at least one packet to be transmitted via a communication network, and participating in at least one tournament composed of a succession of selection rounds. The method includes: obtaining by the station, for each selection round of a first tournament, a binary value assigned to the station, representative either of an authorization to transmit, or of a prohibition to transmit, transmitting, on completion of the first tournament, at least one packet by the station when the station determines, as a function of at least one of the binary values assigned to the station for the selection rounds of the first tournament, that the station is authorized to transmit. The at least one packet transmitted by the station includes data representative of the succession of binary values assigned to the station for the selection rounds.

Abstract: A method and apparatus are provided for regulating transmissions according to a tournament method, implemented by a station having at least one data packet to be transmitted via a wireless communication network having a predetermined bandwidth. The method includes a step during which the station determines whether or not to participate in a tournament, the likelihood of a station participating in a tournament depending on the predetermined bandwidth. Specifically, the likelihood of a station participating in a tournament is selected to be higher as the predetermined bandwidth gets higher.

Abstract: The invention relates to a transmission control method implemented by a station having at least one data frame to be transmitted via a wireless telecommunication network. In one aspect, the method comprises, at each selection round from a maximum number of selection rounds: a step of obtaining a value representative of either an authorization to transmit the frame, or of a prohibition to transmit the frame; and, when the value is representative of an authorization for transmission, transmitting an information signal in the network so as to indicate, to the other stations, that the station has obtained a value representative of an authorization for transmission. The transmission of the information signal is at least partially carried out during the transmission of a data frame in the network.

Abstract: A method and apparatus are provided for regulating sending implemented by a station during a tournament for access to a wireless communication network. The method includes, in the course of a round of the tournament: a step of reception of a first signal, sent by another station and indicating that this other station has obtained during the round of the tournament an authorization to send a data packet, a step of sending of a second signal indicating that the station has received the first signal.

Abstract: A method of regulating sending of data packets, implemented by a station having at least one data packet to be sent via a wireless communication network, includes at least one step of obtaining a binary value representative either of an authorization to send, or of a prohibition to send, a step of sending the packet, the sending step being executed on condition that at least one criterion relating to the binary value or values obtained is satisfied, where the binary value or values are dependent on an index value assigned randomly to the station and a class of packets to which the packet to be sent belongs.

Abstract: A contention resolution system and method are disclosed that can be used in a station having a data packet to send in a wireless telecommunications network. After a predetermined maximum number of selection rounds, it is determined whether the station is authorized to send the packet. In each of the rounds, a value of a binary random variable is drawn, which represents authorization or prohibition, to send the packet during the round. The probability of the binary random variable value assuming a predetermined value is adjusted taking into account authorizations and prohibitions to send the packet obtained by the station during preceding selection rounds.
