A mobile communication device configured for Machine Type Communication (MTC) or configured as a low priority device is provided. In the mobile communication device, a wireless module performs wireless transmissions and receptions to and from a service network, and a controller module transmits a connection request message to the service network via the wireless module in response to initiating a combined attachment procedure or a combined routing area update procedure for both Packet-Switched (PS) and Circuit-Switched (CS) domains, and receives a connection rejection message with an indication of an extended wait timer from the service network via the wireless module. Also, the controller module initiates a location registration procedure for the CS domain or enters a substate in which initiation of the location registration procedure for the CS domain is allowed, in response to the connection rejection message for the PS domain.
