Abstract:
A hard handoff method using a dummy pilot channel comprising the steps of:notifying by a base station manager (BSM) to an applicable base station controller (BSC) and base station (BS) through configuration data that said BS is a dummy pilot BS;sending a pilot signal on air in accordance with dummy pilot data via said BS which has received dummy pilot data;sending a power signal strength message (PSMM) to the base station controller BSC through the base station BS that a mobile station (MS) will perform a PSMM message transmission if the pilot signal strength of a neighboring base station is greater than a threshold value T.sub.-- ADD;determining if said neighboring base station is a dummy pilot cell after said BSC analyzes the received PSMM;sending a handoff direction message (HDM) to the mobile station after said BSC determines said neighboring base station is a target base station, if said neighboring base station is a dummy pilot cell;establishing a channel by synchronizing frequency with an indicated frequency via a mobile station to receive the HDM; andtransmitting by the mobile station a handoff completion message (HCM) to the BSC through the base station that a channel is established.
