Several 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 (175, Fig. 1B) on a mobile device (150, Fig 1B) for intercepting a data request made via a mobile device, and a proxy server (125, Fig 1B) coupled to the mobile device and a content server to which the data request is directed (110, Fig 1B). 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. One embodiment of the distributed proxy and cache system further includes a cache (135, 185, Fig. 1B) shared between the local proxy and the proxy server and the component 185 on the local proxy is queried for a locally stored response to the data request prior to the data request being forwarded on to the proxy server. An optional caching proxy server is also described. The first method described in this application relates to optimizing traffic across a wireless part of the network comprising: using application behavior 602 of multiple applications accessed on a mobile device to detect recurrences 608 in application requests made by the applications; using the recurrences 610, polling of the content sources that would normally be performed by application requests from the mobile device is offloaded and instead performed by a proxy server remote from the mobile device in the wireless network. This minimizes the number of polls that the mobile device performs saving power and also minimizes the number of communications over the expensive final part of the mobile network. The proxy server may notify 612 the mobile device when polls it has performed on behalf of the mobile device indicate that content change has been detected. Application behavior may be detected by tracking patterns in application requests (frequency, interval etc.). |
