Abstract:
1. A method for managing registration signaling by a communication device, wherein the communication device periodically registers with a network at a periodic registration interval, wherein the communication device has a process-on state and a process-off state, and wherein the communication device normally sends an extent of signaling to register with the network upon transitioning from the process-off state to the process-on state, the method comprising: while the communication device is in the process-on state, the communication device periodically recording time at a periodic time-recording interval shorter than the periodic registration interval, whereby the communication device records time more frequently than the communication device registers with the network; upon transitioning from the process-off state to the process-on state, the communication device determining a duration as how much time has passed since a last time that the communication device recorded in accordance with the periodic time-recording interval; and based on at least the determined duration, the communication device limiting the extent of signaling that the communication device sends to register with the network.
