  • Patent number: 12137393
    Abstract: A wireless communication system has an access point managing a first wireless local area network. To transmit the frame, the access point: obtains data to be transmitted in multicast mode; obtains data to be transmitted in unicast mode; and constructs a physical-layer header including: in a common signalling field, an identification of each channel resource intended to be used for making the frame transmission, whether this be for the data to be transmitted in unicast mode or in multicast mode; and, in each field in a series of specific signalling fields, information representing an association between a channel resource identifier used and a unique identifier of the destination concerned or group of destinations concerned. Thus each destination can determine each channel resource to listen to in order to receive the data that are addressed to it, whether this be in unicast mode or in multicast mode.

  • Patent number: 12114379
    Abstract: To pair a plurality of stations with a wireless access point, the wireless access point establishes a multiple pairing. The wireless access point includes, in broadcast beacon frames, a notification of triggering of multiple pairing, during a declaration period of predefined maximum duration. The wireless access point receives, during the declaration period, requests for participation in the multiple pairing coming from said stations. When the declaration period expires, the wireless access point implements individual pairings in turn with each of the stations in question.

  • Patent number: 12096496
    Abstract: A method for connecting a node of a wireless-communication coverage-extension system is provided. The node determines whether it has been moved out of an initial local area network. In the case where the node has been moved, a local area network is established from the moved node by activating an address server functionality. The moved node is then connected to a point of access to the internet. A secure tunnel is next established between the moved node and a master node coordinating the initial local area network. The address server functionality is then deactivated and a client functionality of an address server of the initial local area network is activated.

  • Publication number: 20240205777
    Abstract: A methods/devices are provided for categorizing data streams passing between a station and an access point serving the station to determine whether the station can change access point serving it. The access point serving at least one station: identifies, from an identifier of the source and/or from the destination of the data, each data stream passing between the station and the access point, measures, for each data stream, the quantity of data passing between the station and the access point, calculates, for each data stream, a mean from the measurements for the stream, categorizes each data stream as an interruptible data stream if the mean of the data streams is lower than a first predetermined threshold, and determines that the station can be served by another access point if each stream passing between the station and the access point is categorized as an interruptible data stream.

  • Patent number: 12003611
    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.

  • Patent number: 11985715
    Abstract: This method for managing the connection of a user equipment item to a distributed wireless communication network includes the following steps: sorting access nodes of the distributed wireless communication network into different groups as a function of a primary indicator representative of their quality of connection to a distributed wireless communication network root node and, for at least one access node included in a selected group: determining a secondary indicator representative of a quality of connection of the user equipment item to the access node. If, for each access node included in the selected group, the secondary indicator is strictly greater than a threshold, the steps are repeated with another group containing access nodes having a lower quality of connection to the root node.

  • Publication number: 20240146660
    Abstract: Methods/devices for managing messages broadcast in a local area network (LAN) include nodes allowing an extension of wireless communication coverage and stations. The nodes are connected together by a backhaul subnetwork, and at least one node sends at least one wireless network to which the stations are connected. The LAN includes a primary subnetwork and a secondary subnetwork. The primary subnetwork is a subnetwork to which the links of the backhaul network and the nodes belong. The secondary subnetwork is composed of at least one station and is isolated from the rest of the LAN by a virtual network. A node able to apply the filtering rules demands an analysis of the topology of the local network, determines, from the topology of the LAN, filtering rules to be applied, and applies the filtering rules determined to the broadcast packets including at least one item of information identifying the virtual network.

  • Patent number: 11974222
    Abstract: A method for switching off a communication network is provided. The communication network includes a plurality of access points coordinated by a master device, where each access point manages a wireless network known as a fronthaul network, and where a station is able to associate itself with a fronthaul network of the communication network. At least one item of information relating to each associated station is obtained from each access point, and, for each station, it is determined as to whether it is present or absent according to association information. A phase of switching off at least one fronthaul network is initiated when all the stations are determined as being absent from the communication network.
