  • Publication number: 20120059948
    Abstract: A method is proposed for transmitting at least two data contents by means of a source node to a destination node via at least two transmission paths. The method for transmitting includes steps of: sub-dividing each content into a succession of elementary data groups according to a predetermined pattern of repetition comprising at least two types of different elementary groups; transmitting elementary groups on at least one of the paths, according to a predefined alternation of elementary groups resulting from the sub-division of at least two different contents.

  • Publication number: 20110085523
    Abstract: A method is proposed for managing access to a communications network clocked in transmission cycles by a master node characterized in that, during a given transmission cycle, a slave node of the network performs steps for: obtaining (705) an active access sequence applicable for the given transmission cycle and a piece of information on duration of relevance associated with the active access sequence obtained; carrying out (740) a first check that at least one packet is received by the slave node during the given transmission cycle, according to the active access sequence; in the event of a positive first check, determining (745, 725, 730, 740) an access sequence for a following transmission cycle as a function of pieces of information contained in the received packet or packets; in the event of a negative first check, determining (725, 727, 710, 715, 720, 750, 755) an access sequence for the following transmission cycle as a function of the piece of information on duration of relevance associated with the ac

  • Publication number: 20100195556
    Abstract: The invention pertains to a method for determining a sequence of access (300) to a communications network (100) by a plurality of nodes (101, 102, 103, 5 104, 107) of said communications network (100) in the context of the broadcasting of a data content by a transmitter node (101) to a set of receiver nodes (103, 107, 104, 102), at least one receiver node (102, 104) having to receive said content by means of another receiver node (103, 107), called a relay receiver node.

  • Patent number: 7747783
    Abstract: The communication method concerns communication stations adapted to communicate with each other when a base station supplies a synchronisation signal to mobile stations synchronising on this signal. This method includes a request operation (901) during which a first base station (300) transmits, to a mobile station (301), a request for the storage in memory and transmission, by said mobile station, of a message, to a message destination communication station (302) which is not synchronised with said first base station.

  • Publication number: 20090143024
    Abstract: The invention relates to a method of determining the instant of consideration of a modification of at least one reception condition for signals in a communication system comprising at least two communication devices. The method comprises the steps, executed by a communication device, of: detecting (E702) at least one modification of the reception conditions for signals in the communication system, determining (E703) the instant at which at least one other communication device will have detected the modification of the reception conditions for the signals, establishing (E704) an operating mode of the first communication device as a function of the instant determined. The invention also relates to an associated determining device.

  • Patent number: 7116645
    Abstract: The communication method of the invention applies to communication stations adapted to communicate with each other when at least one of said communication stations supplies a control signal, said station then functioning in “base station” mode and the stations not supplying a control signal then functioning in “mobile station” mode. The method of the invention includes, for at least one communication between two communication stations functioning in mobile station mode, in connection with a first base station: an operation of determining a second station, during which a communication station functioning in mobile station mode able to function in base station mode is determined, a switching request operation during which a message representing a request to switch into base station mode is sent to the second station determined during the determination operation.

  • Publication number: 20060072897
    Abstract: A method for the management of the recording of an audio/video stream within a communications network comprises a step for setting up a first recording connection between a source device and a recording device connected to said communications network. The step for setting up the first recording connection is followed by a step for setting up a second viewing connection between the recording device and a display device also connected to the network, so that a user can observe an audio/video image corresponding to the audio/video stream, on said display device, while the stream is being recorded by the recording device.

  • Patent number: 6826401
    Abstract: For registering a mobile station with a base station, in a telecommunications network, a subscription operation is performed automatically, either following the power-up of the mobile station, if the mobile station is not registered with any base station, or if, after a predetermined period of time (TLOCK), stored in the mobile station, has elapsed, the mobile station has not succeeded in synchronising with and attaching itself to a base station with which the mobile station is already registered.

  • Patent number: 6574452
    Abstract: The communication method of the invention applies to communication stations adapted to communicate with each other when at least one of said communication stations supplies a control signal, said station then functioning in “base station” mode and the stations not supplying a control signal then functioning in “mobile station” mode. It includes, performed by at least one communication station functioning initially in base station mode: an operation of determining the presence of a station functioning in mobile station mode, and when, during the presence determination operation it is determined that no station is functioning in mobile station mode, an operation of switching into mobile station mode, during which said station goes into mobile station node.
