Abstract

To achieve optimum energy savings in a laptop computer and to manage its mobility with the utmost efficiency, a standby mode is planned for this laptop. In this standby mode, a telecommunications card remains in a state of listening to short messages if any. Depending on the short message received, the telecommunications card reactivates (i.e. awakens) or does not reactivate the laptop. If the computer is reactivated, it performs the instructions contained in the short message. It then becomes possible to push the information into a laptop FIG. 3.

Claims

1. A method for reactivating an autonomous computer comprising a wireless connection device wherein:

the wireless connection device receives, through an aerial, a reactivation message comprising at least one field comprising at least one instruction code,

the wireless connection device analyses the reactivation message received to determine whether there are grounds for reactivating the autonomous computer,

if necessary;

the wireless connection device reactivates the autonomous computer,

the autonomous computer performs the operations corresponding to at least the instruction code of at least the field of the activation message.

2. A method according to claim 1, wherein the reactivation message is of the short-message type according to the standards of mobile communications.

3. A method according to claim 1, wherein:

the instruction code corresponds to an instruction to download a digital content,

the short message comprises an identifier of content of the digital content,

once the autonomous computer has been reactivated by the wireless connection device, it sets up a connection in data mode with a telecommunications network to download the digital content identifier by the content identifier.

4. A method according to claim 3, wherein the connection in data mode is set up through the wireless connection device.

5. A method according to claim 3, wherein the connection in data mode is set up through a second interface different from the wireless connection device that has enabled the reception of the reactivation message.

6. A method according to claim 1, wherein:

the instruction code corresponds to an instruction to download a digital content,

the short message comprises an identifier of content of the digital content,

the wireless connection device sets up a connection in data mode for the downloading, into a content memory that it contains, of the digital content identified by the content identifier.

7. A method according to claim 6 wherein:

the wireless connection device reactivates the autonomous computer,

the autonomous computer retrieves the content from the content memory of the wireless connection device.

8. A method according to claim 6 wherein:

a user of the autonomous computer initiates the reactivation of this computer,

the autonomous computer retrieves the content from the content memory of the wireless connection device.

9. A method according to claim 1 wherein, once the operations corresponding to at least the instruction code of at least the field of the reactivation message have been performed, the computer returns to at standby mode.

10. A method according to claim 1, wherein reactivation message comprises at least one field comprising at least one piece of information to authenticate the sender of the reactivation message, the processing of the instruction code being then conditioned by the acceptance of the piece of authenticating information by the autonomous computer.

11. A method according to claim 1, wherein the reactivation of the autonomous computer is partial.

12. A method according to claim 1 wherein, prior to the interpretation of the instruction code of the reactivation message, the wireless connection device analyses the state of the network.
