Mobile application traffic optimization
A system with distributed proxy for reducing traffic in a wireless network satisfies data requests made by a mobile application. The system includes a mobile device having a local proxy for intercepting a data request made by the mobile application. The local proxy simulates application server responses for the mobile application on the mobile device for data requests where responses are available in the local cache. A proxy server is coupled to the mobile device and an application server to which the data request is made. 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. The proxy server queries the application server for any changes to the data request that the mobile application has previously made and notifies the local proxy of such changes.
1. A mobile device having improved resource management, the mobile device comprising:
a memory; and
a processor configured for:
receiving a notification from a remote server directed towards an application, wherein the remote server is an intermediary server that provides connectivity between the mobile device and a first application server and a second application server,
wherein the notification is received over an established multiplexed connection,
wherein the notification indicates new data from the first application server for receipt by the mobile device;
predicting that a user is likely to access the application based on prior application access history;
wherein the application is operating in a background of the mobile device;
wherein a second connection is established while the established multiplexed connection remains connected,
wherein the second connection is other than the established multiplexed connection,
wherein data for the application is fetched based on the prediction,
wherein the fetched data is received over the second connection before the application is accessed,
wherein the fetched data is for background requests made by the application on the mobile device,
wherein the fetched data is delivered to the application; and
disconnecting the second connection.
2. The mobile device of claim 1 , wherein the prior access history includes a time of last access of the application.
3. The mobile device of claim 1 , wherein the prior access history includes a frequency of access of the application.
4. The mobile device of claim 1 , wherein the processor is further configured for:
sending a keep-alive message; and
adjusting a rate of sending keep-alive messages to conserve battery and network resources.
5. The mobile device of claim 4 , wherein the keep-alive messages maintain the multiplexed connection.
6. The mobile device of claim 1 , wherein the processor is further configured for reducing a rate of background data requests allowed to access a network.
7. The mobile device of claim 1 , wherein the mobile device receives a selection from the user whether to enable the application for fetching.
8. The mobile device of claim 1 , wherein a screen status of the mobile device is off when the data is fetched.
