Abstract: A mobile communication device including a Radio Frequency (RF) device and a baseband processor is provided. The RF device performs wireless transmission and reception to and from one or more cells. The baseband processor uses a first subscriber identity to establish a connection with a serving cell via the RF device to perform a first communication procedure, and in response to completing the first communication procedure or the first communication procedure being interrupted by a second communication procedure associated with a second subscriber identity, uses the first subscriber identity to send a measurement report to the serving cell via the RF device. In particular, the measurement report indicates a reported signal quality of the serving cell is poor enough to release the connection.

Abstract: A mobile communication device including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from a service network. The controller determines whether a Radio Resource Control (RRC) security has been activated between the mobile communication device and the service network when receiving measurement configuration from the service network via the wireless transceiver. In response to the RRC security not having been activated and location information of the mobile communication device being present, the controller sends a first measurement report not including the location information of the mobile communication device to the service network via the wireless transceiver, or the controller does not send a second measurement report including the location information of the mobile communication device to the service network via the wireless transceiver.
