In one illustrative example, a mobile communication device has a wireless
transceiver; an antenna coupled to the wireless transceiver; one or more
processors coupled to the wireless transceiver; and a power source
interface which is adapted to connect with a power source for supplying
electrical power to the mobile device. The one or more processors are
operative to monitor a quick paging channel of a wireless communication
network with use of the wireless transceiver; identify whether a
predetermined power source is connected to the power source interface;
cause an indication to terminate use of the quick paging channel to be
transmitted with the wireless transceiver to the wireless network based
on identifying that the predetermined power source is connected to the
power source interface; and refrain from monitoring the quick paging
channel with the wireless transceiver after sending the indication to the
wireless network. In one specific implementation, the mobile device
delays for a time period until a message used for registration is sent to
the wireless network and provides the indication within this message.
