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 system comprising:

a device communicatively connected to an electronic mail server, the device configured for transmitting a request for changed data, the request including expiration data defining a time interval for returning a response to the device from the electronic mail server;

wherein if electronic mail data has changed prior to expiration of the time interval, the device receives a response from the electronic mail server prior to expiration of the time interval, the response including changed electronic mail data; and

wherein when the time interval expires and no electronic mail data has changed, the device receives a notification from the electronic mail server after expiration of the time interval, the notification indicating that no electronic mail data has changed.

2. The system of claim 1, wherein the device comprises a mobile device.

3. The system of claim 1, wherein the system further comprises the electronic mail server.

4. The system of claim 3, wherein the electronic mail server hosts a network application.

5. The system of claim 3, wherein the electronic mail server comprises an electronic mail interface computing device.

6. The system of claim 1, wherein the request for changed data comprises a request for changed electronic mail data.

7. The system of claim 1, wherein the device is further configured for, after receiving a notification indicating that no electronic mail data has changed, transmitting a second request for changed data that includes second expiration data defining a second time interval different from the time interval.

8. The system of claim 7, wherein the second expiration data corresponds to an adjustment of the expiration data based upon a set of events related to communication between the device and the electronic mail server.

9. The system of claim 8, wherein the adjustment of the expiration data is based at least in part on a network condition.

10. An electronic mail server configured for receiving a request for changed data, the request including a set of expiration data defining a time interval for returning a response to the device from the electronic mail interface computing device;

wherein if electronic mail data has changed prior to expiration of the time interval, the electronic mail server transmits a response prior to expiration of the time interval, the response including changed electronic mail data; and

wherein when the time interval expires and no electronic mail data has changed, the electronic mail server transmits a notification after expiration of the time interval, the notification indicating that no electronic mail data has changed.

11. The electronic mail server of claim 10, wherein the request for changed data is received from a device communicatively connected to the electronic mail server.

12. The electronic mail server of claim 11, wherein the device is located remote from the electronic mail server.

13. The electronic mail server of claim 10, wherein the electronic mail server hosts a network application.

14. The electronic mail server of claim 10, wherein the electronic mail server comprises an electronic mail interface computing device.

15. The electronic mail server of claim 10, wherein the request for changed data comprises a request for changed electronic mail data.

16. A method comprising:

transmitting from the device a request for changed data to an electronic mail server, the request including a set of expiration data defining a time interval for returning a response to the device from the electronic mail server;

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

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.

17. The method of claim 16, wherein the method further comprises:

monitoring at the device time elapsed between a first time at which the request for changed data is transmitted and a second time at which the response or the notification is received; and

transmitting a second request for changed data including a second set of expiration data for returning a response, the second set of expiration data defining a second time interval that differs from the time interval.

18. The method of claim 16, wherein transmitting the request for changed data comprises transmitting a request for changed electronic mail data.
