Abstract
A method of performing a handover from a Wideband Code Division Multiple Access (WCDMA) system to a Code Division Multiple Access (CDMA) system in a multi-mode terminal having a WCDMA module and a CDMA module includes determining whether a handover to the CDMA system is necessary during a call through a WCDMA system; acquiring a pilot signal from the CDMA system by activating the CDMA module if it is determined that the handover to the CDMA system is necessary; receiving a sync signal if the pilot signal from the CDMA system is acquired; transmitting information for handover to the WCDMA system through the WCDMA module; allowing the CDMA module to enter a CDMA traffic state using handover information if the handover information is received from the WCDMA system through WCDMA module; and releasing a traffic state of the WCDMA module.
