Methods and systems for managing registration signaling based on off-time duration
First Claim
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.

Abstract
Systems and methods are disclosed herein for managing the extent of registration signaling that a communication device sends when activating a network process, based on how long the process was turned off. For instance, if the device turns off without deregistering from a communication network and then turns on while the network registration is still current, an example system or method may help the device to recognize this situation and reduce unnecessary signaling associated with restarting a network process.

10. A communication device comprising:
-
a network interface for engaging in network communications, wherein the network interface normally periodically engages in network registration at a periodic registration interval, and wherein the network interface engages in an extent of network registration when the communication device transitions from a process-off state to a process-on state; and control logic for (i) periodically recording time at a periodic time-recording interval shorter than the periodic registration interval, (ii) upon transitioning of the communication device from the process-off state to the process-on state, determining a current time and determining a duration as how much time has passed from a last time that the communication device recorded at the periodic time-recording interval to the determined current time, and (iii) limiting the extent of network registration based on the determined duration. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method for managing network registration by a communication device, wherein the communication device normally periodically engages in network registration at a registration interval, and wherein the communication device normally engages in an extent of network registration when the communication device transitions from a power-off state to a power-on state, the method comprising, upon transitioning of the communication device from the power-off state to the power-on state:
-
the communication device determining a current time; the communication device comparing the determined current time to a last time that the communication device recorded at a periodic time-recording interval shorter than the registration interval, to determine a duration from the last time that the communication device recorded at the period time-recording interval to the determined current time; and the communication device limiting the extent of network registration based on the determined duration that the communication device was in the power-off state. - View Dependent Claims (19)
