Abstract: A wireless communication system includes a first access point managing a first wireless local area network and at least one second access point managing at least one respective wireless local area network. A CSMA/CA procedure is employed. The first access point is involved in a real-time sensitive transmission. Each access point implements an energy detection mechanism and a preamble detection mechanism in the context of the CSMA/CA procedure. The energy detection mechanism is implemented for accessing the primary channel and for accessing each secondary channel. The preamble detection mechanism is implemented for accessing the primary channel and optionally for accessing each secondary channel. A decision making unit instructs the first access point and each second access point to use the same primary communication channel. This improves the conditions under which the real-time sensitive transmission takes place.

Abstract: An item of ONU equipment configures itself to communicate by a first transport system with OLT equipment in an optical access network, and starts a synchronisation for the first transport system and transmits by means of the first transport system. The ONU equipment transmits, via a protocol layer supervising any transport system of the optical access network, without waiting for the end of the synchronisation for the first transport system, information dependent on identifiers of the user equipment and the first transport system. When the transport system to be used is not the first transport system, the protocol layer supervising any transport system of the optical access network interrupts the synchronisation at the OLT equipment, and the ONU equipment reattempts the synchronisation with a second transport system; otherwise the synchronisation continues for the first transport system until the ONU equipment is put in communication in the optical access network.

Abstract: An interconnection device for interconnecting between first and second networks, between which there pass critical data streams having a bandwidth reservation requirement in order to ensure rate and latency constraints, performs, for each critical data stream, the interconnection device: measuring an effective rate of said critical data stream; checking whether said measured effective rate is greater than the sum of a previously reserved bandwidth and a tolerance bandwidth; checking whether said measured effective rate is lower than the previously reserved bandwidth, from which the sum of a margin bandwidth and tolerance bandwidth is deducted; and in the event of positive check, adjusting bandwidth reservation for said critical data stream to a value equal to the sum of the measured effective rate for said critical data stream and the margin bandwidth.

Abstract: Determined is a topology of a communication network composed of a plurality of nodes connected or not respectively to at least one item of equipment, one of the nodes, referred to as the root node, being connected to an external network. A service class is determined for each node, from each node, information is obtained representing the quality of the link between the node and other nodes, for each link, parameters representing the quality of the link are calculated, the nodes are classified according to the service class thereof and according to the number of links making up the path that separates them from the root node, for each node and according to the classification, the possible paths connecting the node to the root node are determined, a score is calculated for each path determined, the path is selected for the node having the best score.

Abstract: In order to configure a communication device connected to a wireless network including N communication channels, the communication device being adapted for communicating via one communication channel at a time, means of selection of a channel from amongst the N communication channels enables: selecting a communication channel with an unknown disturbance level, when the disturbance level of at least one communication channel is unknown; and otherwise selecting the least disturbed communication channel. Dynamic configuration means include means for reactivating the selection means in case of disturbances representing unsatisfactory transmission conditions on the selected communication channel according to a predetermined criterion. The dynamic configuration means are deactivated when the selection means have been reactivated N times.

Abstract: Some appliances, normally supplied by a mains supply, comprise an emergency supply by batteries able to take over from the mains supply. The batteries used by the emergency supply are generally protected by a fuse. These appliances may consume energy greater than what could be supplied by the batteries of the emergency supply. When there is a break in the mains electrical supply, it's preferable to limit the current consumed by the appliance to not damage the fuse protecting said batteries. However, the fuses are hardware modules having a reaction time of a few hundreds of milliseconds. If one does not want to damage the fuse, one could reduce the current consumption of the appliance within a time less than the reaction time of the fuse. A system and method herein instantaneously reduces the electrical consumption of an appliance in the event of a break in the mains supply.

Abstract: A method and a device is provided for managing an operating fault in a laser diode of an optical interface of user equipment of the ONU type. The user equipment is connected by an optical access network of the passive optical network PON type to line termination equipment of the OLT type. The user equipment is enabled to send an optical signal during a time slot allocated to the user equipment in accordance with a time-division multiple access principle. The laser diode is checked as to whether it is transmitting an optical signal outside the allocated time slot and, if so, a message to the line termination equipment is transferred if the fault is detected, deactivation of the laser diode is demanded, and one or more procedures for attempting to correct the fault are implemented.

Abstract: An item of ONU equipment configures itself for communicating via a first transport system with an item of OLT equipment in an optical access network, and starts a synchronisation for the first transport system and transmits via the first transport system. The OLT equipment transmits, via a protocol layer fitting on top of the entire transport system of the optical access network, without waiting for the synchronisation for the first transport system to have ended, a message indicating which transport system is to be used by the ONU equipment. When the transport system to be used by the ONU equipment is the first transport system, the synchronisation continues the first communication system, otherwise the synchronisation is restarted for the second transport system.

Abstract: A method and a device for anticipating a reconnection, to a second access point, of a mobile station connected to a first access point that forms a wireless telecommunication network. The physical bit rate between the first access point and mobile station with respect to a reception power of a signal sent by a mobile station and received by the first access point from measurements of reception power of signals sent by the mobile station and received by the first access point, calculates physical bit rates between access points and mobile station. A rate of variation of the physical bit rates between access points and mobile stations from measurements obtained and from the modelling, an anticipation of physical bit rate between access points and the mobile stations and determines whether a reconnection of the station to the second access point must be made among other things from the calculated anticipations.
