1. A method for operating a terminal in a wireless communication system including an advanced network and a legacy network, the method comprising:

  • monitoring a paging channel of the legacy network for a data paging message and a Circuit Switched (CS) paging message, when the terminal is in an idle state after switching from an active state;

    receiving one of the CS paging message and data paging message;

    establishing a connection with the legacy network corresponding to the received one of the CS paging message and data paging message, wherein a CS voice connection is established with the legacy network if the CS paging message is received and a Packet Switched (PS) data connection is established with the legacy network if the data paging message is received; and

    performing a handover to the advanced network from the legacy network, if the PS data connection is established with the legacy network.
