ABSTRACT:
A hard handoff method is provided whereby a mobile station communicates with a base station to execute the handoff over a CDMA channel using only a pilot channel. The method does not require the use of a sync, paging, access, or traffic channel to carry out the handoff procedure. Unlike the conventional handoff in which a base station detects the signal strength of a mobile station continuously and performs a handoff if the signal strength falls below a predetermined threshold, the "Dummy Pilot" method requires the mobile station to provide the base station with handoff information, and the base station performs the handoff in accordance with the provided information.
