Abstract:
1. A method for handing-off a mobile unit from a current base station to a candidate base station in a CDMA communication system comprising a plurality of base stations, the method comprising the steps of: receiving by a mobile unit transmissions from a plurality of candidate base stations, each transmission containing a global pilot code; acquiring a global pilot code from one of the candidate base stations using global pilot code seed stored in a memory of the mobile unit; establishing a communication link to the candidate base station from which the mobile unit acquires a global pilot code with a minimum transmit power; comparing the transmit power to the candidate base station with the transmit power to the current base station; and completing a hand-off from the current base station to the candidate base station if the transmit power to the candidate base station is less than the transmit power to the current base station.
