Abstract
A system, device and method are described for operating a communication device communicating with a wireless network. The method comprises in a power save mode wherein a communication subsystem of the communication device has been deactivated: for a first period beginning at a first instance, re-activating the subsystem, executing an action relating to a link layer connection condition, and then de-activating the subsystem; and for a second period beginning at a second instance, re-activating the subsystem, executing an action relating to a network layer connection condition, and then de-activating the subsystem. For the method, the first period is repeated on a cycle based on a first frequency timed to allow the communication device to process a beacon signal from the wireless network; and the second period is repeated on a cycle based on a second frequency of occurrence of an Address Resolution Protocol request in the wireless network.
