Abstract

Message transmission system, including first and second networks (2, 3) of devices, and at least one mobile device (6, 7) provided with a non-volatile memory, each mobile device (6, 7) including a first communication means (16) configured to establish an automatic connection with at least one device (E1 to E5) of the first network (2), a second communication means (17) configured to establish an automatic connection with at least one device (4, 5) of the second network (3), and message processing means (15) configured to transmit messages stored in the non-volatile memory of the mobile device to each connected device, and to save the messages transmitted by the mobile device in the non-volatile memory of the mobile device.

Claims

1. A method for transmitting messages between a first network of devices and a second network of devices, comprising:

at least one mobile device provided with a non-volatile memory,

a first communication step comprising at least one automatic connection between a mobile device and at least one device of the first network, and

a second communication step comprising at least one automatic connection between a mobile device and at least one device of the second network,

each automatic connection comprising transmitting the messages stored in the non-volatile memory of the mobile device of the automatic connection to each connected device,

the method comprising saving the messages transmitted by each mobile device in the non-volatile memory of the mobile device.

2. The method according to claim 1, wherein each connection of the first communication step comprises an automatic connection of a mobile device with devices belonging to the first network only.

3. The method according to claim 1, wherein each connection of the second communication step comprises an automatic connection of a mobile device with a single device belonging to the second network.

4. The method according to claim 1, wherein the automatic connections are simultaneous or asynchronous.

5. The method according to claim 1, wherein each device comprises a non-volatile memory for storing messages to be transmitted, each connection of the first communication step comprising transmitting the messages stored in the non-volatile memory of each device of the first connected network to the non-volatile memory of the mobile device of the connection, each connection of the second communication step comprising transmitting the messages stored in the non-volatile memory of each device of the second connected network to the non-volatile memory of the mobile device of the connection, and the saving step comprises saving each message transmitted by each device in the non-volatile memory of the device which transmits the message.

6. The method according to claim 5, wherein the messages stored in the non-volatile memory of the device of the first network comprise application messages intended for at least one addressee device belonging to the second network, the messages stored in the non-volatile memory of the devices of the second network comprise application messages intended for at least one addressee device belonging to the first network, the method comprising a processing of the transmitted messages comprising, for each application message received by the device having the application message addressed thereto, storing in the non-volatile memory of the addressee device an acknowledgement message associated with the received application message, and the processing step comprising, for each acknowledgement message received by a device, suppressing from the non-volatile memory of the device the application message associated with the received acknowledgement message.

7. The method according to claim 6, wherein each application message comprises a unique non-zero identifier, and each device stores in its non-volatile memory a serial number initialized at the zero value, and the step of processing the transmitted messages comprises suppressing the application message received by a device if the identifier of the received application message is less than or equal to the serial number of the device, and incrementing the serial number of the device if the identifier has a value consecutive to that of the serial number of the device.

8. A system for transmitting messages, comprising:

first and second networks of devices, and

at least one mobile device provided with a non-volatile memory,

wherein each mobile device comprises;

a first communication means configured to establish an automatic connection with at least one device of the first network,

a second communication means configured to establish an automatic connection with at least one device of the second network, and

a message processing means configured to transmit messages stored in the non-volatile memory of the mobile device to each connected device, and to save the messages transmitted by the mobile device in the non-volatile memory of the mobile device.

9. The system according to claim 8, wherein each first communication means is configured to establish an automatic connection with devices belonging to the first network only.

10. The system according to claim 8, wherein each second communication means is configured to establish an automatic connection with a single device belonging to the second network.

11. The system according to claim 8, wherein the first and second communication means are configured to establish automatic connections simultaneously or asynchronously.

12. The system according to claim 8, wherein each device comprises a non-volatile memory for storing messages to be transmitted, each device of the first network comprises a message processing means configured to transmit the messages stored in its non-volatile memory to the non-volatile memory of the mobile device to which it is connected, each device of the second network comprises a message processing means configured to transmit the messages stored in its non-volatile memory to the non-volatile memory of the mobile device to which it is connected, each device having a message processing means configured to save the messages transmitted by the device in the non-volatile memory of the device.

13. The system according to claim 12, wherein the messages stored in the non-volatile memory of the devices of the first network comprise application messages intended for at least one addressee device belonging to the second network, the messages stored in the non-volatile memory of the devices of the second network comprise application messages intended for at least one addressee device belonging to the first network, each message processing means being configured to store, in the non-volatile memory of an addressee device which receives an application message addressed thereto, an acknowledgement message associated with the received application message, and to suppress from the non-volatile memory of a device which receives an acknowledgement message the application message associated with the received acknowledgement message.

14. The system according to claim 13, wherein each application message comprises a unique non-zero identifier, each non-volatile memory comprises a serial number initialized at the zero value, and each message processing means is configured to suppress the application messages received by a device if the identifier of the received application message is less than or equal to the serial number of the device, and to increment the serial number of the device if the identifier has a value consecutive to that of the serial number of the device.

15. The system according to claim 8, wherein the first network of devices corresponds to the Internet and each mobile device is a wireless smartphone.
