Abstract:
Method for managing a distribution of bandwidth in a communications network, corresponding computer-readable storage medium and slave node.A method is proposed for managing a distribution of bandwidth in a communications network by means of a slave node of the network, said network comprising a set of nodes.The slave node is such that it performs steps for: determining a coarse representation and a detailed representation of the distribution of the bandwidth in said network, as a function of a piece or pieces of information relative to conditions of transmission in said network and/or relative to applications needs of transmission; receiving a coarse reference representation of the distribution of bandwidth in said network, coming from a master node of said network; comparing said determined coarse representation and said reference coarse representation; should said coarse representations be identical, applying said determined detailed representation; if not, applying said coarse reference representation.
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.
Abstract:
A method of transmitting a video frame over a plurality of communication channels involves selecting a number of communication channels available between the transmitting and the receiving devices; partitioning spatially correlated pixels of the video frame into a number of different partitions equal to the number of selected communication channels; and transmitting the different partitions, where each partition is transmitted on a distinct communication channel among the selected communication channels.Such a method is suitable for use in a communication system, especially a wireless communication system, in which data of a channel can be lost or corrupted. The method can maximize diversity in the transport of the video frame pixels and improve robustness.
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.
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, and 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.

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.

Abstract:
This method of managing the resources of a computer communication means for processing a computer document stored on a processing control device connected by the communication means to at least one processing device includes a step of selecting at least one processing device of the communication means as a function of a first group of criteria relating to the functioning of this device, and a second group of criteria relating to its geographical situation.
