Abstract
A method () and device () for saving energy in a wireless communication device configured to maintain a persistent communication session over a wireless network with an application server are disclosed. The method () can include: opening () a persistent communication session with an application server via a cellular network; measuring () a round trip time from sending a message to the application server to receiving an acknowledgement message from the application server; and automatically transitioning () the device from a first operating state to a second operating state after an amount of time in the absence of subsequent data traffic exceeding a predetermined threshold, wherein power consumption associated with the second operating state is less than power consumption associated with the first operating state, and the predetermined threshold is a function of the measured round trip time.
