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.

Abstract: Concepts and examples pertaining to enhancement for wireless local area network (WLAN) measurement in mobile communications, such as Evolved Universal Terrestrial Radio Access (E-UTRA), are described. A processor of an electronic apparatus receives a message from a network, with the message including a measurement object listing one or more WLANs associated with the electronic apparatus except for a first WLAN to which the electronic apparatus is communicatively connected. The processor performs measurement of one or more aspects of the one or more WLANs and the first WLAN. The processor also reports to the network a result of the measurement regarding the one or more WLANs and the first WLAN, even though the first WLAN was not listed in the measurement object received from the network.
