Abstract

Device for updating the date and time of an electronic system, said device comprising connection means for connecting the electronic system with an assisted global positioning system, recovery means for recovering assistance data emitted by the assisted global positioning system, determination means for determining the current date and time of the electronic system based on said recovered assistance data, and control means capable of activating the connection, recovery and determination means.

Claims

1. A method of updating the date and time of an electronic system, comprising a connection with an assisted global positioning system, a recovery of assistance data emitted by the assisted global positioning system and a determination of the current date and time of the electronic system based on said recovered assistance data.

2. The method according to claim 1, wherein the recovery of assistance data includes a recovery of the number of the current week and of the current time of said current week.

3. The method according to claim 1, wherein the updating of the date and time of the electronic system is performed when the electronic system is started up.

4. The method according to claim 1, wherein the updating of the date and time of the electronic system is performed periodically.

5. A device for updating the date and time of an electronic system, comprising connection means for connecting the electronic system with an assisted global positioning system, recovery means for recovering assistance data emitted by the assisted global positioning system, determination means for determining the current date and time of the electronic system based on said recovered assistance data, and control means capable of activating the connection, recovery and determination means.

6. The device according to claim 5, wherein the recovery means are capable of recovering a number of the current week and a current time of said current week.

7. The device according to claim 5, wherein the control means are capable of activating the connection, recovery and determination means when the electronic system is started up.

8. The device according to claim 5, wherein the control means are capable of periodically activating the connection, recovery and determination means.

9. An electronic system comprising means of supplying the date and time and a device for updating the date and time of the electronic system according to claim 5.

10. The electronic system according to claim 9, forming a wireless communication appliance.
