Virtual pilot channel generating apparatus and its operating method for supporting effective hand-off between frequencies in CDMA mobile communications system
A virtual pilot channel generating apparatus and its operating method for supporting effective hand-off between frequencies in a CDMA mobile communications system, in which, when base stations A and B use frequency channels different from each other and a user moves from the base station A to base station B, pilot information the same as CDMA allocation frequency used in the base station A is supplied to the hardware of the base station B, and the hardware of the base station B transmits a virtual pilot channel identical to CDMA allocation channel used in the base station A, to allow the user's mobile to simultaneously monitor power intensities of the pilot channels of the base stations A and B, initiating smooth hand-off.
