Apparatus and method for providing an automatic handoff process of a
dual-mods user equipment (UE) from either a wireless local area network
(WLAN) to a universal mobile telecommunications system (UMTS) or from a
UMTS to a WLAN. Handoffs may be initiated by the UE, based upon user
preference, signal quality, comparison of location coordinates of the UE
and the system to be switched to or signal quality. The available
channels of one system may be sent to the UE by the other system or the
UE may monitor channels of the system to be switched to and lock on to
one. The handoff may also be initiated by the UMTS, the selection being
power-based.
