Abstract

A system with distributed proxy for reducing traffic to satisfy data requests made in a wireless network is provided. The system includes a mobile device having a local proxy for intercepting a data request made via the mobile device and a proxy server coupled to the mobile device and a content server to which the data request is directed. The proxy server is able to communicate with the local proxy and the local proxy forwards the data request to the proxy server for transmission to the content server for a response to the data request. The proxy server sends the data request to the content server independent of activities on the local proxy and notifies the local proxy when different content on the content server is detected for the data request

Claims

1. A system with distributed proxy for reducing traffic to satisfy data requests made in a wireless network, the system, comprising:

a mobile device having a local proxy for intercepting a data request made via the mobile device; and

a proxy server coupled to the mobile device and a content server to which the data request is directed;

wherein, the proxy server is able to communicate with the local proxy, the local proxy forwards the data request to the proxy server for transmission to the content server for a response to the data request;

wherein, the proxy server sends the data request to the content server independent of activities on the local proxy and notifies the local proxy when different content on the content server is detected for the data request.

2. The system of claim 1, further comprising,

a cache shared between the local proxy and the proxy server;

wherein, the cache includes component on the local proxy and is queried for a locally stored response to the data request prior to the data request being forwarded on to the proxy server.

3. The system of claim 1, wherein, the local proxy identifies the data request which yields same results returned from the content server and notifies the proxy server to monitor responses received for the same data request made in the future for changed results prior to sending the result to the local proxy.

4. The system of claim 1, wherein, traffic between the proxy server and the content server is optimized at the protocol level.

5. A system with distributed proxy for reducing traffic in a wireless network to satisfy data requests made by a mobile application the system, comprising:

a mobile device having a local proxy for intercepting a data request made by the mobile application;

the local proxy simulating application server responses for the mobile application on the mobile device for data requests where responses are available in the local cache; and

a proxy server coupled to the mobile device and an application server to which the data request is made;

wherein, the proxy server is able to communicate with the local proxy, the local proxy forwards the data request to the proxy server for transmission to the application server for a response to the data request;

wherein, the proxy server queries the application server independent of activities of the mobile application for any changes to the data request that the mobile application has previously made and notifies the local proxy of such changes.

6. The system of claim 5, wherein, the wireless network includes the cellular network.

7. The system of claim 5, wherein, the wireless network includes a WiFi network.

8. A system with distributed proxy for reducing network resources used for keep-alive messages in a wireless network, the system, comprising:

a mobile device having a local proxy; and

a proxy server coupled to the local proxy and a content server to which application requests from the mobile device are directed;

wherein, the proxy server is able to communicate with the local proxy, the local proxy prevents keep-alive messages from being sent from the mobile device over the wireless network;

wherein, the proxy server generates the keep-alive messages to maintain connectivity with the content server.

9. The system of claim 8, wherein the local proxy is transparent to an application on the mobile device.

10. The system of claim 8, wherein the local proxy is bundled into a wireless modem.

11. The system of claim 8, wherein the local proxy is bundled into a firewall or router.

12. The system of claim 8, wherein, the proxy server generates the keep-alive messages independent of the operations of the local proxy on the mobile device.
