Abstract

An information service such as an airport information system relies on a network of Bluetooth™ transceivers to transfer information to a user'"'"'s mobile phone, which is equipped with basic calendar functionality. The transceivers are connected to (an information server, which downloads the calendar from each of the devices and writes or updates the reminder in each device as appropriate. The mobile phone calendar therefore provides a backup in the event that the user moves outside of the network coverage, while the server carries out all of the necessary processing, so that the system does not rely on complex calendar software within the mobile devices.

Claims

1. A method of providing an information service from an information server (1) to a portable device (6), wherein the portable device (6) is operative to store time dependent information provided by the server (1), the method comprising the steps of:

requesting data relating to the information stored at the portable device (6);

determining the current status of the stored information from the requested data; and

transmitting new or updated information from the server (1) to the portable device (6) in accordance with the determined status.

2. A method according to claim 1, wherein the step of requesting data relating to the stored information comprises reading calendar information from the portable device (6).

3. A method according to claim 1, wherein the information service is provided over a predetermined area, further comprising the step of determining user information associated with the device (6) when the device enters the predetermined area.

4. A method according to claim 1, wherein the time dependent information comprises information relating to an action that is scheduled to occur at a specified time.

5. A method according to claim 4, wherein the step of determining the status of the information comprises determining if the device is arranged to provide a reminder relating to the action.

6. A method according to claim 5, further comprising, in the event that the device is not arranged to provide the reminder, writing a reminder to the device (6).

7. A method according to claim 5, further comprising, in the event that the device is arranged to provide the reminder, determining if the reminder is up-to-date.

8. A method according to claim 7, further comprising, in the event that the reminder is not up-to-date, updating the reminder on the device (6).

9. A method according to claim 7, comprising determining if the reminder is up-to-date by comparing timestamp information associated with the stored reminder with timestamp information associated with a latest available reminder.

10. A method according to claim 7, comprising determining if the reminder is up-to-date by comparing the time at which the stored reminder is set to remind the user of the action with the time at which a latest available reminder would be set to remind the user of the action.

11. A method according to claim 4, further comprising providing an alert to the device (6) in relation to the action, receiving the alert at the device and notifying the alert to the user in preference to notifying the user of a reminder stored at the device.

12. A method according to claim 11, further comprising deleting the stored reminder on receipt of the alert.

13. A method according to claim 11, comprising, in the event that the device does not receive the alert, notifying the stored reminder to the user.

14. An information server (1) for providing an information service to a portable device (6), wherein the portable device (6) is operative to store time dependent information provided by the server (1), the server (1) being configured to:

request data associated with the information stored at the portable device (6);

determine the current status of the stored information from the requested data; and

transmit new or updated information to the portable device (6) in accordance with the determined status.

15. An information server (1) according to claim 14, further comprising at least one transceiver (2-5) connected to the server (1) for communicating with the portable device (6).

16. An information server according to claim 14, wherein the server (1) is arranged to retrieve calendar information stored on said device for the purpose of determining the current status of the information.

17. A server according to claim 14, operable to connect to a database (8) that includes user information.

18. A portable device (6) for receiving an information service from an information server (1), the device (6) comprising:

means for storing time related information provided by the server (1);

means operative to provide data associated with the time related information stored at the device (6) in response to a request from the information server; and

means for overwriting stored information in response to updated information received from the server (1).

19. A portable device (6) according to claim 18, wherein the data associated with the time related information comprises calendar information stored at the device.
