  • redirecting the terminal to a target cell supporting circuit domain business when a first call request is received in a first serving cell not supporting the circuit domain business;

    sending a location area update request to a base-station where the target cell is located, when a plurality of location area identities (LAIs) stored do not comprise a LAI of the target cell, wherein the plurality of LAIs are received from a base-station where the first serving cell is located; and

    identifying the base-station where the target cell is located as a pseudo base-station, when no message corresponding to the location area update request is received from the base-station where the target cell is located during a first preset time length, and an interval at which the terminal conducts a location area update as indicated by the base-station where the target cell is located is longer than a second preset time length or shorter than a third preset time length, wherein the second preset time length is longer than the third preset time length.
