Device, system and method of universal-mode communication with power saving

摘要

Devices, systems, and methods are provided to enable power saving when operating a communication device in an idle state in a Universal Mobile Telecommunications System. In some embodiments a method is provided to enable universal mode communication devices operating in a Universal Mobile Telecommunications System to determine whether a serving base station transmits signals using a selected Radio Access Technology (RAT) during an idle state of operation. In the case where the serving base station transmits signals using a non-selected RAT, the communication device may select a neighboring base station where an adequate signal is provided using the selected RAT, irrespective of the signal strength in the cell being served.
