Classification: CPC H | IPC H

Claim 0:
1. A method, executed by a mobile communications device camping on a first cell using a first Radio Access Technology (RAT), the method comprising:
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;
wherein when the first RAT is fifth generation (5G) New Radio (NR) and the second RAT is fourth generation (4G) Long Term Evolution (LTE), the sending of the first measurement report comprises sending the first measurement report in response to the determined data transmission rate being lower than a first threshold;
wherein when the first RAT is 4G LTE and the second RAT is 5G NR, the sending of the first measurement report comprises sending the first measurement report in response to the determined data transmission rate being higher than a second threshold; and
wherein the first threshold and the second threshold are not related to each other.
