  • Patent number: 7705726
    Abstract: A device suitable for wireless communication with a network entity. The device comprises a functional unit configured to monitor an operational state of the device and, in response to detecting that the device is in a de-powered operational state, to inform the network entity of an ability of the device to wirelessly communicate with the network entity during a future time interval while the device remains in a de-powered operational state. A second functional unit capable of wireless communication with the network entity may also be provided and may be selectably powered from either a main power source or an alternate power source such that the second functional unit is powered from the alternate power source during the future time interval and becomes unpowered from the alternate power source after the future time interval. Thus, de-powered devices can be located and communicated with more easily.

  • Publication number: 20080089255
    Abstract: A system for communicating with a wireless-enabled device. The system comprises an input for receiving from the device a signal indicative of the device being in a de-powered operational state; a functional entity configured to determine, on a basis of (i) knowledge that the device is in the de-powered operational state and (ii) context information regarding the device, a certain action to be taken by the device while in the de-powered operational state; and an output for causing transmission of a message to the device, wherein the message is for causing the device to take the certain action while in the de-powered operational state.
