Abstract
A method that reduces power consumption in a wireless communication device having a first and a second modem. The method includes detecting access to a communication network via the second modem, and in response to that detection: establishing a communication channel between the second modem and a communication service over a communication network; and triggering the first modem to enter a sleep state. The communication service is configured to respond to receipt at the communication service of an incoming communication to be routed to the first modem via a first communication network by: (i) automatically transmitting a notification via the communication channel to the second modem and (ii) forwarding the incoming communication via the first communication network to the first modem. The method then includes, in response to receipt of the notification at the device: awakening the first modem to an active state to enable receipt of the incoming communication.
