Abstract

A method of policy management for network resource use optimization in a wireless network. The method includes detecting, by a proxy server, that multiple mobile clients are requesting content polls directed towards a common host server, the proxy server being wirelessly coupled to the multiple mobile clients, polling, by the proxy server, the common host server for the content requested by the multiple mobile clients, and sending the content received from the common host server to each of the multiple mobile clients such that each client need not make individual polls to the common host server.

Claims

1. A method of policy management for network resource use optimization in a wireless network, the method, comprising:

detecting, by a proxy server, that multiple mobile clients are requesting content polls directed towards a common host server, the proxy server being wirelessly coupled to the multiple mobile clients;

polling, by the proxy server, the common host server for the content requested by the multiple mobile clients;

sending the content received from the common host server to each of the multiple mobile clients such that each client need not make individual polls to the common host server.

2. The method of claim 1, wherein the requesting of content polls directed towards the common host server are occurring within a time period.

3. A method of policy management for network resource use optimization in a wireless network, the method, comprising:

tracking, by a proxy server, network conditions in a specific network area, the proxy server being wirelessly coupled to mobile clients in the specific network area;

setting polling schedules for the mobile clients in the specific network area according to the network conditions.

4. The method of claim 3, wherein the setting the polling schedules includes adjusting the polling frequency made to content hosts.

5. The method of claim 3, wherein the proxy server adjusts content delivery schedule to the mobile clients from content hosts.

6. The method of claim 4, wherein the polling frequency made to the content hosts is adjusted by blocking or adjusting the schedule of at least some polls from the mobile clients from reaching the wireless network.

7. The method of claim 4, wherein the at least some polls are block from reaching the wireless network until indication of changed or different response at the content hosts is detected.

8. The method of claim 4, wherein, the polling frequency is adjusted based on a number of mobile clients serviced in the specific network area.

9. The method of claim 4, wherein, the polling frequency is adjusted based on a number of mobile clients serviced in the specific network area.

10. The method of claim 3, further comprising, communicating the polling schedules to the mobile clients in the specific network area;

wherein the polling schedules instruct the mobile clients to poll on different schedules so as to avoid congestion.

11. The method of claim 3, further comprising,

detecting, by the proxy server, network congestion in the specific network area;

reducing polling frequency for content made to hosts made by the mobile clients serviced in the specific network area.

12. The method of claim 11, wherein, network congestion is determined based on reduced data transfer speeds in the wireless network.

13. The method of claim 11, wherein, network congestion is determined based on higher retransmission rates on lower level protocols.

14. The method of claim 11, wherein, network congestion is determined based on failure of mobile clients in the specific network area to be able to connect to the wireless network.

15. The method of claim 12, wherein, the failure to connect is reported by local proxies on the mobile clients able to communicate with the proxy server.

16. The method of claim 11, wherein, the network congestion is reported by a network operator.

17. The method of claim 3, wherein, the polling frequency is reduced for content made by applications meeting a criterion.

18. The method of claim 15, wherein, the criteria includes, low priority application, or applications running in the background as opposed to the foreground.

19. The method of claim 3, wherein, the local proxies of respective mobile clients create traffic profiles of applications installed on the mobile clients and transfers the traffic profiles to the proxy server for use in managing network resources in the wireless network.

20. A system for policy management for network resource use optimization in a wireless network, the system, comprising:

means for, tracking network conditions in a specific network area;

means for, adjusting the polling frequency made to content hosts based on a number of mobile clients serviced in the specific network area;

means for, detecting, by the proxy server, network congestion in the specific network area;

means for, reducing polling frequency for content made to hosts made by the mobile clients serviced in the specific network area.

21. The system of claim 20, further comprising, means for, setting polling schedules for mobile clients serviced in the specific network area according to the network conditions.

22. A machine-readable storage medium having stored thereon instructions which when executed by a processor performs a method of policy management for network resource use optimization in a wireless network, the method, comprising:

detecting that multiple mobile clients are requesting content polls directed towards a common host server;

polling the common host server for the content requested by the multiple mobile clients;

sending the content received from the common host server to each of the multiple mobile clients such that each client need not make individual polls to the common host server.

23. The method of claim 22, further comprising:

tracking network conditions in a specific network area;

setting polling schedules for the mobile clients in the specific network area according to the network conditions;

detecting network congestion in the specific network area;

reducing polling frequency for content made to hosts made by the mobile clients serviced in the specific network area.

adjusting content delivery schedule to the mobile clients from content hosts.
