Terminal and method for switching between radio access technologies
A method includes determining whether a packet switched (PS) signaling connection is released, the PS signaling connection being associated with a first network corresponding to a first radio access technology (RAT), controlling a switching timing to a second network corresponding to a second RAT according to a type of the PS signaling connection, and transmitting a request for switching to the second network. A terminal includes a controller to determine whether a packet switched (PS) signaling connection is released, the PS signaling connection being associated with a first network corresponding to a first radio access technology (RAT), and to control a switching timing to a second network corresponding to a second RAT according to a type of the PS signaling connection, and a transmitter to transmit a request for switching to the second network.

determining that a call using a first network is terminated;
in response to determining that the call using the first network is terminated, determining that a signaling connection for location registration exists, the signaling connection being associated with the first network;
in response to determining that the signaling connection for location registration exists, completing procedures for location registration;
in response to completing the procedures for location registration, transmitting a signaling connection release indication (SCRI) message; and
switching from the first network to a second network.
