Abstract
Methods and apparatus are provided for saving energy in a mobile device configured to maintain a persistent communication session with an application server over a wireless network. A method comprises detecting a traffic pattern between a mobile device and an application server for maintaining a persistent communication session and automatically initiating a transition of the mobile device from a first operating state to a second operating state in response to detecting the traffic pattern. The power consumption associated with the second operating state is less than power consumption associated with the first operating state.
