摘要:
A method for waking up a plurality of sleeping devices. Each sleeping device is coupled to a waking device over a communications network and is adapted to provide a service feature to the waking device upon a request for the service feature from the waking device. The waking device sends a request for service to a network element of the communications network, which is always on. The network element receives the request for service, determines which features are requested by the waking device, and wakes up the sleeping devices that provide these requested features.
