Apparatuses and methods for coordinating operations associated with multiple subscriber identities

A method for coordinating operations associated with multiple subscriber identities, executed by a controller of a mobile communication device which comprises a Radio Frequency (RF) device, the method comprising:

• providing a Packet-Switched (PS) data service using a first subscriber identity via the RF device;
• establishing a Radio Resource Control (RRC) connection using a second subscriber identity via the RF device to enable the mobile communication device to enter an RRC connected mode associated with the second subscriber identity;
• receiving a notification of an incoming Circuit-Switched (CS) Mobile Terminated (MT) call for the second subscriber identity via the RF device;
• and
• after receiving the notification of the incoming CS MT call for the second subscriber identity, keeping the mobile communication device in the RRC connected mode associated with the second subscriber identity while providing the PS data service using the first subscriber identity.
