Abstract

A mobile communication device including a first RF device, a second RF device, and a controller is provided. The first and second RF devices perform wireless transmission and reception utilizing a first RAT and a second RAT, respectively. The controller detects, during a communication with a first cell using a first subscriber identity, an incoming event for making a voice call or conducting a data session using a second subscriber identity via the second RF device, and switches the communication associated with the first subscriber identity to a second cell which utilizes the first RAT in a frequency band on which dual connectivity over the first and second RATs is supported, or enables the voice call associated with the second subscriber identity to be made via the first RF device when the communication associated with the first subscriber identity is performed via the second RF device.
