Abstract: A mobile communication device supporting wireless communications using a first subscriber identity and a second subscriber identity is provided. The mobile communication device includes a Radio Frequency (RF) device and a controller. The controller is coupled to the RF device such that the controller performs the following actions: performing a first measurement on a cell via the RF device by using the first subscriber identity to obtain a first measurement result; determining whether the first measurement result is valid; and based on a result of the determining, performing a second measurement on the cell via the RF device by using the second subscriber identity to obtain a second measurement result.

Abstract: A method for improving service continuity is provided. The method is implemented by a reduced capability (RedCap) user equipment (UE) and includes generating a not-allowed cell list of new radio (NR) standalone (SA) cells. The method includes avoiding performing a mobility decision on the NR SA cells recorded in the not-allowed cell list during a mobility procedure or a measurement reporting procedure.

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 dual Subscriber Identity Module (SIM) transmission method is provided. The dual SIM transmission method may include the following steps. A first SIM of an apparatus may perform a first service from a first serving cell. Then, a processor of the apparatus may determine whether the apparatus needs to be switched to a dual SIM dual active (DSDA) mode in response to a second SIM of the apparatus requiring a second service while the first SIM is performing the first service. In response to determining that the apparatus needs to be switched to the DSDA mode, the processor may select a target cell to make the apparatus support the DSDA mode.

Abstract: A capability reporting method and a modem chip performing the same are provided. The capability reporting method includes the following steps. A capability enquiry message is received from a network. A plurality of weightings for a serving Radio Access Technology (RAT) and at least one non-serving RAT are determined. The weighting for the at least one non-serving RAT is downgraded. A plurality of capability information for the serving RAT and the non-serving RAT are composed according to the weightings. The size of the capability information for the at least one non-serving RAT is reduced. The capability information for the serving RAT and the capability information for the at least one non-serving RAT are combined to obtain a capability report message. The capability report message is replied to the network.

Abstract: A method for enhancing mobility of a communications apparatus is provided. The method includes the steps of: establishing a connection with a cell; measuring one or more parameters of one or more cells; transmitting a measurement report to a network device according to the measured parameters of the one or more cells; determining whether a mobility command is received from the network device after transmitting the measurement report; and triggering a connection release procedure based on no mobility command being received from the network device after transmitting the measurement report.

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.
