  • Patent number: 12277613
    Abstract: A method for connecting a smart electricity meter connected to a data concentrator, referred to as the current data concentrator, in a powerline or radio-frequency communication network for the automated management of metering in the context of an electrical distribution service is described. The smart electricity meter disconnects from the current data concentrator in the case where the latter is posing a problem. It next attaches itself to a neighbouring data concentrator different from the current data concentrator. It then listens to the frames containing an identifier of said current data concentrator. Finally, it disconnects from the neighbouring data concentrator and attaches itself to a data concentrator using the same identifier as the current data concentrator when at least N frames containing the identifier of the current data concentrator are received, with N an integer greater than or equal to 1.

  • Patent number: 11477174
    Abstract: A modem of a smart electricity meter obtains, following a registration in the powerline communication network of the ad hoc type, routing information and encryption information, by exchanges of messages in the powerline communication network. The smart electricity meter saves in non-volatile memory the routing information and the encryption information, the routing information being saved in association with information representing an instant at which the backup is made. At the time of a subsequent re-registration of the smart electricity meter following a disconnection of the powerline communication network, the smart electricity meter retrieves the routing and encryption information previously saved in the non-volatile memory, updates it by deleting any route information that is no longer valid, and uses it to communicate in the powerline communication network.

  • Patent number: 10742265
    Abstract: A method for access to a shared communication medium, referred to as the medium, access to the medium being of the “carrier sense multiple access” type, wherein an electronic device, in order to be able to send a message over the medium, the message including information representing a message type, waits for a backoff time before checking whether the medium is available to send the message, the backoff time being determined randomly and lying between a minimum backoff time and a maximum backoff time, wherein the maximum backoff time is dependent on the type of message to be sent over the medium by the electronic device.

  • Patent number: 10469620
    Abstract: A new version of a software is broken down into successive blocks in order to be transferred block by block in two phases by a concentrator device: a first phase during which said concentrator device performs (S308) the transfer according to a sequencing independent of whether or not each block has been correctly received, and a second phase during which the concentrator device performs (S310) the transfer of each block that has not been correctly received. The new version of the software is thus transferred to electricity meters via a communication network.
