Abstract

A system and method for facilitating communications between a mobile device and a network application are provided. A mobile device transmits a request for data change information that includes a time out interval. The network application receives the request and measures a time elapsed since the receipt of the data change request. The network application will only transmit a notification to the mobile device client if new data is received or the time out interval has elapsed. As notifications are received, the mobile client device tunes the time out interval based upon network and device parameters.

Claims

1. A method comprising:

transmitting from a device a request for changed data to an electronic mail server;

if electronic mail data on the electronic mail server has changed prior to expiration of a time interval for returning a response to the device, receiving a response at the device from the electronic mail server prior to expiration of the time interval, the response including an indication of changed electronic mail data; and

if the time interval expires and no electronic mail data has changed, receiving a notification at the device from the electronic mail server after expiration of the time interval, the notification indicating that no electronic mail data has changed.

2. The method of claim 1, wherein the request includes a set of expiration data defining the time interval.

3. The method of claim 1, wherein the device comprises a mobile device.

4. The method of claim 1, wherein the time interval defines a time in which the electronic mail server is requested to provide a positive or negative response to the request.

5. The method of claim 1, wherein the device transmits the request via a secure data transmission protocol.

6. The method of claim 1, wherein the request comprises a registration request with the electronic mail server.

7. The method of claim 1, wherein the time interval is set by the device.

8. The method of claim 1, further comprising transmitting from the mobile device a second request, the second request including a set of expiration data for returning a response defining a second time interval different from the time interval.

9. The method of claim 8, wherein the second time interval is based at least in part on a network condition.

10. The method of claim 8, wherein the second time interval is based at least in part on user input at the device.

11. The method of claim 1, wherein, if electronic mail data has changed prior to expiration of the time interval, the response includes an indication to the mobile device to transmit a data request to the electronic mail server.

12. The method of claim 1, wherein the indication of changed electronic mail data includes metadata descriptive of the changed data.

13. The method of claim 12, wherein the metadata allows a user to preview, at the device, at least a portion of a message included in the changed electronic mail data.

14. The method of claim 1, wherein the request includes user authentication information.

15. The method of claim 1, wherein the time interval is measured at the electronic mail server based on a time of receipt of the request.

16. A system comprising:

a mobile device configured for transmitting a request to an electronic mail server;

wherein, the mobile device is configured to, if electronic mail data on the electronic mail server has changed prior to expiration of a time interval for returning a response to the device, receive a response at the device from the electronic mail server prior to expiration of a time interval, the response including an indication of changed electronic mail data; and

wherein, the mobile device is configured to, if the time interval expires and no electronic mail data has changed, receive a notification at the device from the electronic mail server after expiration of the time interval, the notification indicating that no electronic mail data has changed.

17. The system of claim 16, further comprising the electronic mail server, wherein the electronic mail server maintains a communicative connection to the mobile device during the time interval.

18. The system of claim 17, further comprising a plurality of devices communicatively connected to the electronic mail server, the plurality of devices including the mobile device.

19. The system of claim 17, wherein the mobile device is communicatively connected to the electronic mail server via a secure data transmission protocol.
