ABSTRACT:
An apparatus and method for efficiently processing a dormant state in a packet service between communication networks providing the packet service using different mobile communication technologies is disclosed. This method includes disconnecting, by a multi-mode terminal, a current packet call and changing to a new serviceable mode, if a multi-mode terminal moves to a poor communication area in a dormant or preservation state occurring during a packet service. In this state, by immediately returning to a packet call reconnection state if a user performs a subsequent operation, an area in which the packet service cannot be provided can be minimized, and a communication mode in which a best communication service can be provided can be established.
