Abstract

A push proxy server for pushing data to a wireless device having a coverage state of online or offline. The push proxy server comprises a coverage state detector, memory, a data store, and a transceiver. The coverage state detector determines the coverage state of the wireless device. The memory stores a coverage state indicator for indicating the coverage state of the wireless device. The data store stores the data to be pushed to the wireless device when the coverage state indicator indicates the wireless device is offline. The transceiver transmits the data to the wireless device when the coverage state indicator indicates the wireless device is online. A method for implementing the push proxy server is also described.

Claims

1. A push proxy server for pushing data to a wireless device having a coverage state of online or offline, the push proxy server comprising:

(a) a coverage state detector for determining the coverage state of the wireless device;

(b) memory for storing a coverage state indicator for indicating the coverage state of the wireless device;

(c) a data store for storing the data to be pushed to the wireless device when the coverage state indicator indicates the wireless device is offline; and

(d) a transceiver for transmitting the data to the wireless device when the coverage state indicator indicates the wireless device is online.

2. The push proxy server of claim 1 wherein the transceiver further transmits data from the data store to the wireless device when the coverage state detector detects a change from offline to online.

3. The push proxy server of claim 2 wherein the coverage state detector determines that the wireless device is offline if a data transmission fails a predefined number of times.

4. The push proxy server of claim 2 wherein the coverage state detector determines that the wireless device is online upon receipt of a heartbeat message.

5. The push proxy server of claim 2 wherein the coverage state detector determines that the wireless device is online upon receipt of a pull request.

6. The push proxy server of claim 1 further comprising a waste manager for deleting stale data from the data store in accordance with a predefined expiry term.

7. The push proxy server of claim 6 wherein the expiry field indicates that the stale data is to be deleted at a predefined time.

8. The push proxy server of claim 6 wherein the expiry field indicates that the stale data is to be deleted after a predefined duration.

9. The push proxy server of claim 6 wherein the expiry field indicates that the stale data is to be deleted upon receipt of replacement data.

10. The push proxy server of claim 6 wherein the waste manager overwrites the predefined expiry term with an expiry term received along the push data.

12. The method of claim 6 further comprising the step of transmitting data from the data store to the wireless device when the coverage state detector detects a change from offline to online.

13. The method of claim 12 the wireless device is determined to be offline if a data transmission fails a predefined number of times.

14. The method of claim 12 wherein the wireless device is determined to be online upon receipt of a heartbeat message.

15. The method of claim 12 wherein the wireless device is determined to be online upon receipt of a pull request.

21. A computer readable medium comprising instructions, which, when executed on a computer, cause the computer to implement the method of claim 1.

11. A method for pushing data from a push initiator to a wireless device having a coverage state of online or offline, method comprising the steps of:

(a) determining, at a push proxy server, the coverage state of the wireless device;

(b) storing in memory a coverage state indicator for indicating the coverage state of the wireless device;

(c) storing in memory the data to be pushed to the wireless device when the coverage state indicator indicates the wireless device is offline; and

(d) transmitting the data to the wireless device when the coverage state indicator indicates the wireless device is online.

16. The method of claim 11 further comprising the step of deleting stale data from the memory in accordance with predefined expiry term.

17. The method of claim 16 wherein the expiry field indicates that the stale data is to be deleted at a predefined time.

18. The method of claim 16 wherein the expiry field indicates that the stale data is to be deleted after a predefined duration.

19. The method of claim 16 wherein the expiry field indicates that the stale data is to be deleted upon receipt of replacement data.

20. The method of claim 16 further comprising the step of overwriting the predefined expiry term with an expiry term received along the push data.
