Abstract

Systems and methods for mobile application traffic optimization are disclosed. In one aspect, embodiments of the present disclosure include a distributed proxy and cache system, including, a local proxy on a mobile device for intercepting a data request made via a mobile device, and a proxy server coupled to the mobile device and a content server to which the data request is directed. In one embodiment, the local proxy can forward the data request to the proxy server for transmission to the content server for a response to the data request. In addition, the proxy server sends the data request to the content server independent of activities on the local proxy and notifies the local proxy when changed or different content on the content server is detected for the data request.

First claim

What is claimed is:

1. A method for reducing traffic in a cellular network used to satisfy data requests made by a mobile application, the method comprising:
intercepting, on a mobile device, a first data request made by the mobile application;
querying a local cache on the mobile device;
determining that a locally stored first response is invalid;
querying a remote proxy for a remotely stored first response responsively to the locally stored first response being determined invalid;
providing the remotely stored first response to the mobile application without the mobile application accessing the cellular network;
intercepting a second data request made by the mobile application on the mobile device;
querying the local cache on the mobile device;
determining that a locally stored second response is valid;
providing the second response to the mobile application without the mobile application accessing the cellular network;
sending the first data request to a content source via forwarding through the remote proxy;
notifying the remote proxy to monitor responses received for the first data request from the content source for changed results;
receiving, from the remote proxy in response to notifying the remote proxy to monitor, a notification that a changed result from the content source is detected; and
replacing a locally stored response on the mobile device when notified of the changed result.

2. The method of claim 1 , further comprising, receiving a response provided by the content source through the remote proxy, and locally storing the response in the local cache on the mobile device for subsequent use in satisfying additional data requests.

3. The method of claim 1 , wherein the notifying is performed when the first data request to the content source has yielded same results to be returned to the mobile device.

4. The method of claim 1 , further comprising, storing the first response to the local cache for the first data request when the remote proxy is notified to monitor the responses received for the first data request.

5. The method of claim 1 , wherein, the remote proxy performs the data request identified for monitoring and notifies the mobile device when an unexpected response to the data request is detected.

6. The method of claim 1 , wherein, the mobile application includes a web-browsing application.

7. The method of claim 1 , wherein the mobile application includes a video streaming application.
