Optimizing keepalive and other background traffic in a wireless network

A mobile device implementing network transaction optimization, comprising:

• a processor;
• a memory;
• a radio;
• the processor being configured to:
• identify a keepalive period of a mobile application executing on the mobile device, wherein the mobile application is connected to a server;
• determine a pull-in period by:
• tracking traffic patterns of the mobile device;
• using the traffic patterns of the mobile device to determine a first probability and a second probability,
• wherein the first probability is the probability of the mobile application consuming resources, and
• wherein the second probability is the probability of the radio of the mobile device turning on;
• and
• calculating the pull-in period based on the first probability and the second probability, wherein the pull-in period is a value selected to minimize the mobile application's consumption of resources and the number of instances where the radio of the mobile device needs to be turned on;
• wherein the pull-in period has a shorter duration than the keepalive period;
• when the mobile application has been idle for longer than the pull-in period, detecting whether the radio of the mobile device turns on;
• and
• in response to detecting the radio of the mobile device turn on, trigger a new keepalive to the server before the end of the keepalive period.
