Abstract: A method for switching between different RATs is provided. The method is executed by a mobile communications device camping on a first cell using a first Radio Access Technology (RAT). The method includes: determining, by a controller of the mobile communications device, a data transmission rate of the mobile communications device in the first cell; sending, by the controller, a first measurement report according to the determined data transmission rate, wherein the first measurement report is intended to trigger a handover procedure initiated by the first cell or to release a radio resource control (RRC) connection; and switching, by the controller, to camp on a second cell using a second RAT via the handover procedure or a local releasing procedure after the sending of the first measurement report.

Abstract: A power optimization method for uplink data transmission is provided. The power optimization method is applied to user equipment (UE). The power optimization method includes the following steps. The UE determines the current application scenario of the UE. The UE determines the data transmission window corresponding to the current application scenario. Data transmission windows corresponding to different application scenarios of the UE have at least one of different period to transmit data and different period to enter suspension. The UE may transmit data based on the determined data transmission window.
