Provided is a function of minimizing a delay time of a packet call disconnect due to a handover between communication networks providing a communication service using different mobile communication technologies. To do this, even though a handover situation is generated during a packet service, the packet service is continuously provided by maintaining a current mode and performing a mode change after registration in a handover target network succeeds. Accordingly, since the packet service is not provided only while a packet call connecting process is performed, a delay time according to a packet call reconnection can be minimized. |
