One or more packets associated with a wakeup event for a mobile user device is/are delayed, thereby extending the duration of the wakeup event. Because the duration of the wakeup event is extended, the start of the next wakeup event for the mobile user device is delayed by a time interval, and therefore the signaling load on the mobile network is reduced during this time interval compared to the signaling load that would have been on the mobile network if the start of the next wakeup event had not been delayed. If the delayed packet(s) is/are data packet(s), then the disclosure presents a solution which involves data to solve a problem relating to signaling.
