Abstract

A communications system may include a client device for generating email processing jobs and a proxy server communicating asynchronously over the Internet with the client device for processing the email processing jobs. The client device may post a given email processing job to the proxy server with a unique job identifier (ID), and the proxy server thereafter may post job results for the given email processing job to the client device also with the unique job ID. The client device may also advantageously post at least one other email processing job to the proxy server over the Internet at a time between posting the given email processing job and receiving the job results therefor.

Claims

1. A communications system comprising:

a client device for generating email processing jobs; and

a proxy server communicating asynchronously over the Internet with said client device for processing the email processing jobs;

said client device posting a given email processing job to said proxy server with a unique job identifier (ID), and said proxy server thereafter posting job results for the given email processing job to said client device also with the unique job ID;

said client device posting at least one other email processing job to said proxy server over the Internet at a time between posting the given email processing job and receiving the job results therefor.

2. The communications system of claim 1 wherein said client device also generates and posts calendar processing jobs to said proxy server, and wherein said proxy server processes and posts results for the calendar processing jobs to said client device.

3. The communications system of claim 1 wherein said client device also generates and posts address book processing jobs to said proxy server, and wherein said proxy server processes and posts results for the address book processing jobs to said client device.

4. The communications system of claim 1 wherein said client device also generates and posts document retrieval processing jobs to said proxy server, and wherein said proxy server processes and posts results for the document retrieval processing jobs to said client device.

5. The communications system of claim 1 wherein said client device and said proxy server communicate asynchronously over the Internet at a physical layer.

6. The communications system of claim 1 wherein said client device posts the given email processing job to said proxy server using a Web Distributed Authoring and Versioning (WebDAV) protocol.

7. The communications system of claim 1 further comprising at least one wireless handheld communications device cooperating with said client device to generate the email processing jobs.

8. The communications system of claim 1 wherein said client device initiates a first connection with said proxy server to post the given email processing job, and wherein said proxy server initiates a second connection different than the first connection with said client device for posting the job results for the given email processing job.

9. The communications system of claim 1 wherein said proxy server comprises a queue for storing processing jobs posted by said client device prior to processing.

10. The communications system of claim 1 wherein said proxy server sends an acknowledgement to said client device upon receiving the posted given processing job, and wherein said client device sends an acknowledgement to said proxy server upon receiving the posted job results for the given processing job.

11. A communications system comprising:

a client device for generating email and calendar processing jobs; and

a proxy server communicating asynchronously over the Internet with said client device for processing the email and calendar processing jobs;

said client device posting a given email or calendar processing job to said proxy server with a unique job identifier (ID), and said proxy server thereafter posting job results for the given email or calendar processing job to said client device also with the unique job ID;

said client device posting at least one other email or calendar processing job to said proxy server over the Internet at a time between posting the given email or calendar processing job and receiving the job results therefor.

12. The communications system of claim 11 wherein said client device also generates and posts document retrieval processing jobs to said proxy server, and wherein said proxy server processes and posts results for the document retrieval processing jobs to said client device.

13. The communications system of claim 11 wherein said client device and said proxy server communicate asynchronously over the Internet at a physical layer.

14. The communications system of claim 11 wherein said client device initiates a first connection with said proxy server to post the given email or calendar processing job, and wherein said proxy server initiates a second connection different than the first connection with said client device for posting the job results for the given email or calendar processing job

15. A communications system comprising:

a client device for generating email and address book processing jobs; and

a proxy server communicating asynchronously over the Internet with said client device for processing the email and address book processing jobs;

said client device posting a given email or address book processing job to said proxy server with a unique job identifier (ID), and said proxy server thereafter posting job results for the given email or address book processing job to said client device also with the unique job ID;

said client device posting at least one other email or address book processing job to said proxy server over the Internet at a time between posting the given email or address book processing job and receiving the job results therefor.

16. The communications system of claim 15 wherein said client device also generates and posts document retrieval processing jobs to said proxy server, and wherein said proxy server processes and posts results for the document retrieval processing jobs to said client device.

17. The communications system of claim 15 wherein said client device and said proxy server communicate asynchronously over the Internet at a physical layer.

18. The communications system of claim 15 wherein said client device initiates a first connection with said proxy server to post the given email processing job, and wherein said proxy server initiates a second connection different than the first connection with said client device for posting the job results for the given email processing job.

19. A communications method comprising:

generating email processing jobs at a client device;

posting a given email processing job from the client device to a proxy server over the Internet with a unique job identifier (ID);

processing the given email processing job at the proxy server and posting job results for the given email processing job to the client device over the Internet also with the unique job ID; and

posting at least one other email processing job from the client device to the proxy server over the Internet at a time between posting the given email processing job and receiving the job results therefor.

20. The method of claim 19 further comprising:

generating calendar processing jobs at the client device and posting the calendar processing jobs to the proxy server; and

processing the calendar processing jobs at the proxy server and posting results therefor to the client device.

21. The method of claim 19 further comprising:

generating address book processing jobs at the client device and posting the address book processing jobs to the proxy server; and

processing the address book processing jobs at the proxy server and posting results therefor to the client device.

22. The method of claim 19 further comprising:

generating document retrieval processing jobs at the client device and posting the document retrieval processing jobs to the proxy server; and

processing the document retrieval processing jobs at the proxy server and posting results therefor to the client device.

23. The method of claim 19 wherein the client device and the proxy server communicate asynchronously over the Internet at a physical layer.

24. The method of claim 19 wherein posting the given email processing job comprises posting the given email processing job to the proxy server using a Web Distributed Authoring and Versioning (WebDAV) protocol.

25. The method of claim 19 wherein said client device initiates a first connection with said proxy server to post the given email processing job, and wherein said proxy server initiates a second connection different than the first connection with said client device for posting the job results for the given email processing job.
