A method of handling an inter-RAT handover for a mobile device (10) in a wireless communication system includes when, via a handover from a serving network (12) using a first RAT to a target network (14) using a second RAT, the mobile device (10) succeeds in establishing a connection to the target network (14) and has packet switched data for transmission, transmitting a predetermined radio resource control message, indicating existence of a packet switched signaling connection of the mobile device (10), to the target network (14). |
