Abstract

The invention relates to a method for controlling a device operating in several operating modes corresponding to different levels of power consumption and comprising a first and a second communication interface, said method being characterized in that it comprises the steps of activating said second communication interface upon receiving a first wake-up message via said first interface and receiving a second wake-up message via said second communication interface, said second wake-up message resulting in the exit from the low-power standby mode of the device.

First claim

The invention claimed is:

1. A method for controlling a device, said device operating in several operating modes corresponding to different levels of power consumption and comprising a first and a second communication interface for communicating with other devices belonging respectively to a first and a second network, wherein said method comprises:
activating said second communication interface upon receiving a first wake-up message via said first communication interface when said device is in a first operating mode corresponding to a first level of power consumption, said activation resulting in a second level of power consumption higher than said first level of power consumption;
receiving a second wake-up message via said second communication interface, said second wake-up message resulting in the closure of power supply lines with a view to supplying power to a control unit, an exit from a standby mode, and consequently a transition of said device to an operating mode corresponding to a third level of power consumption, said third level of power consumption being higher than said second level of power consumption.

2. The method according to claim 1 , wherein said first operating mode corresponds to a configuration of said device wherein only said first communication interface is activated.

3. The method according to claim 1 , wherein said second operating mode corresponds to a configuration of said device wherein only said first and second communication interface are activated.

4. The method according to claim 1 , wherein said first communication interface is a wireless communication interface.

5. The method according to claim 1 , wherein said second communication interface is a network interface of Ethernet type.

6. The method according to claim 1 , wherein said second communication interface is a wireless network interface, compatible with the 802.11 transmission standards.

7. A device operating in several operating modes corresponding to different levels of power consumption and comprising a first and a second communication interface for communicating with other devices belonging respectively to a first and a second network, said device further comprising a memory and at least one processor coupled to the memory, the at least one processor being configured to:
activate said second communication interface upon receiving, via said first communication interface a first wake-up message when said device is in a first operating mode corresponding to a first level of power consumption, said activation resulting in a second level of power consumption higher than said first level of power consumption; and
control said device upon receiving via said second communication interface a second wake-up message, said second wake-up message resulting in the closure of power supply lines with a view to supplying power to a control unit, an exit from a standby mode, and consequently a transition of said device to an operating mode corresponding to a third level of power consumption, said third level of power consumption being higher than said second level of power consumption.

8. The device according to claim 7 , wherein said first operating mode corresponds to a configuration of said device wherein only said first communication interface is activated.

9. The device according to claim 7 , wherein said second operating mode corresponds to a configuration of said device wherein only said first and second communication interface are activated.

10. The device according to claim 7 , wherein said first communication interface is a wireless communication interface.

11. The device according to claim 7 , wherein said second communication interface is a network interface of Ethernet type.

12. The device according to claim 7 , wherein said second communication interface is a wireless network interface, compatible with the 802.11 transmission standards.
