Abstract
A method for waking up user equipment in a cellular network includes waking up a receiver module at a predetermined wakeup time to receive a transmitted paging signal, when awake, determining prevailing conditions for receiving paging signals, and skipping at least a next possible wakeup time if at least one of the prevailing conditions exceeds an associated threshold level. A user equipment for use on a mobile communications network includes a reception quality determiner to determine at least one of a reception quality of a received signal and a radio frequency (RF) level of the signal, a paging indication processor to process received paging signals, a system message handler to determine a level of activity for a cellular network, and a conditional wakeup mechanism that is configured to set a next wakeup for the user equipment time responsively to an input from at least one of the reception quality determiner and the system message handler.
