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: Various solutions for measurement report enhancement with respect to user equipment and network apparatus in mobile communications are described. An apparatus may initiate a voice or video call with a network node. The apparatus may determine whether Single Radio Voice Call Continuity before alerting stage (bSRVCC) is supported by the network node. The apparatus may cancel a transmission of a measurement report to the network node before an alerting stage when the bSRVCC is not supported by the network node. The apparatus may perform the voice or video call with the network node.
