Method for reading information from a set of electricity meters
Electric meters are connected by an electricity supply network to a data concentrator with which the meters communicate by powerline. A method for reading information from meters is based on a classification of the meters in a plurality of classes. A first class, read first, groups together meters that haven't been read in a last execution of the method. The other classes group together the meters according to a rate of response to requests for information coming from the concentrator. The classes grouping together the meters that have the lowest response rates are read last. In each class, each meter is classified according to information representing a topology of the network having an influence on the failure risk of the transmissions of information by the meter. The concentrator accounts for the classification of the meters when the meters in the network are read to reduce occurrences of periods of contention.

A method for detecting a resending of a frame, each frame sent that includes an identifier and a counter, the counter remaining identical during a resending, each frame sent being received by a plurality of gateways, each gateway retransmitting each frame to a central server, a response delay being predefined, the method comprising the steps of receiving a first frame comprising an identifier and a counter, storing as reference parameters a first reception time and the counter, receiving a second frame comprising the same identifier and another counter, and, if the values of the counters are equal then determining a second reception time of the second frame, and, if the difference between the reception times is greater than the response delay, then the second frame is a resending of the first frame, and updating the reference parameters with the second reception time.
An LPWAN communication system includes server equipment, at least one gateway and at least one relay. Each gateway communicates with terminals using a Class A communication mode, wherein any response intended for a terminal uses a reception window defined with respect to a transmission time of an original message by said terminal. Each relay is seen as a terminal by each gateway, and communicates with terminals in accordance with a Class A′ communication mode, defined as follows: the relay transmits beacons at regular intervals and listens out to terminals only during timeslots defined with respect to said beacons. In this Class A′ communication mode, the relay propagates any response toward a terminal using at least one other reception window defined with respect to a transmission time of an original message by said terminal.
Some protocols for the transmission of data on a communication network, such as the LoRaWAN protocol, use frames comprising payloads intended to transport useful data, the size of which may vary from one frame to another. A communication method is proposed in order to transmit data on this type of network. This method is based on a division of a payload packet into a set of blocks and then an insertion of the blocks thus formed into at least one segment. Each segment comprises a number of blocks suited to a payload size at the time of creation of the segment. The segments are next supplemented with verification information enabling an addressee of the data packet to determine whether it has received all the blocks. In the event of non-reception of all the blocks, the sender of the blocks retransmits at least the blocks not received.
The invention relates in particular to a method executed by a control device, for a mesh communication network, allowing selection of an optimum frequency band, the method comprising the steps of determining network quality information, if the quality information is below a first threshold, then: sending, to each device in the network, a message comprising an instruction to perform a frequency band quality test, collecting, at the end of the quality test, for each device, quality data for each frequency band, determining, for each frequency band, a quality indicator, and selecting a so-called optimum frequency band as being the frequency band associated with the best indicator, when the so-called optimum frequency band is different from the frequency band used, then sending, to each device, an instruction to use the so-called optimum frequency band.
In the context of management of handover roaming, a communication system comprises a first LPWAN network of a first operator and a second LPWAN network of a second operator. The first network comprises gathering gateways, a first server managing the gathering gateways, and a second server controlling the MAC layer. The second network comprises a third server interfacing fourth and fifth servers with the second server. Uplink frames of application data are transported from an end device of the second operator to the fourth server by successive relayings of the first, second and third servers. However, when the end device of the second operator requests joining the communication system in order to benefit from the services of the fourth server, the gathering gateways communicate with the fifth server, short-circuiting the first, second and third servers.

A communication system comprises a first LPWAN network of a first operator and a second LPWAN network of a second operator. The first network comprises subnetworks implementing separate respective transport protocols. The subnetworks comprise at least one convergence node and communication nodes integrating gathering gateways. The first network comprises servers interconnected to a server of the second network interfacing an application server and an authentication server. Uplink frames of application data are transported from an end device of the second operator to the application server by successive relayings of the servers. However, when the end device of the second operator requests to join the communication system in order to benefit from the services of the application server, the gathering gateways communicate directly with the authentication server by shortcutting the other servers as well as the convergence nodes to which said gathering gateways are respectively attached.
