User equipment, cellular communication network node and method of controlling operation of a user equipment

摘要

A user equipment comprises a wireless interface for communication with a cellular communication network. The user equipment has different operating states which include a power saving state. Transitions between the power saving state and a further operating state different from the power saving state may be triggered by a device-to-device signal received directly from a further user equipment.

主权项

1. A user equipment, comprising:
a wireless interface for communication with a cellular communication network, and a control logic configured to control transitions of the user equipment between different operating states which include a power saving state, the control logic being configured to process a device-to-device signal received directly from a further user equipment at the wireless interface and to selectively execute, in response to the received device-to-device signal, a transition of the user equipment between the power saving state and a further operating state different from the power saving state, the transition being triggered by the received device-to-device signal, wherein the control logic is configured to control the wireless interface to perform a tracking area update, TAU, procedure in response to the device-to-device signal.
