Abstract: Systems and methods for extending delay tolerance of mobile applications to optimize mobile traffic management are disclosed. In a mobile device, network stack timers or protocol stack timers are modified to extend delay tolerance of applications for radio alignment. In an embodiment, tolerance of mobile applications on a mobile device to delay in establishing a connection to a wireless network is extended by an application or a local proxy on a mobile device. Based on the tolerance that is extended, requests intercepted from the mobile applications are aggregated, over a period of time, such that transfer of the requests intercepted during the period of time is delayed. This minimizes the number of times the mobile device connects to the network, reducing the power consumption on the mobile device and unnecessary signaling in the network.

Abstract: A system with a distributed proxy is provided. Additionally, a mobile device with power management and optimization is provided. The mobile device may alter characteristics or behavior in order to conserve battery power and reduce signaling.

Abstract: Detection of network transactions or keepalives for maintaining long lived connections are disclosed. A keepalive detector can detect keepalive traffic based on keepalive parameters determined from an analysis of socket level network communication log data that record data transfer events including data sent from mobile applications or clients on a mobile device and data received by the mobile applications or clients on the mobile device, timing characteristics, protocol types, etc. Various statistical analyses can be performed on the network communication data to detect keepalives, taking into account variability in intervals of the data transfer events and sizes of data sent and received on each event. The keepalive detector can also detect keepalives from stream data on a mobile device by analyzing socket level communication messages including timing characteristics and amount of data transferred to detect keepalives and report keepalives using a data structure.

Abstract: A system with distributed proxy for reducing traffic in a wireless network to satisfy data requests made by a mobile application is provided. 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 independent of activities of the mobile application for any changes to the data request.
