A novel method and apparatus for initiating a reverse link intergenerational handoff in a CDMA communication system is disclosed. The inventive reverse link intergenerational handoff initialization method and apparatus measures and compares parameters between a serving base station of one generation and a target base station of another generation to determine the best possible handoff initiation time instant for performing a reverse link intergenerational hard handoff. The method and apparatus can utilize one of several embodiments to determine the best possible handoff initiation time instant. A pilot signal strength embodiment determines a handoff initiation time instant based upon the total pilot signal strength of both a serving and target base station. The Eb/Nt embodiment determines a handoff initiation time instant based upon Eb/Nt (ratio of average power per bit to total received power spectral density) values of both a serving and a target base station. The disclosed method and apparatus decreases the probability of degraded or dropped calls during intergenerational handoffs.
A method of initiating a reverse link portion of a handoff that has previously been directed between a serving base station and a target base station in a CDMA communication system having a plurality of base stations in communication with at least one mobile station, wherein each base station transmits at least one associated and corresponding pilot channel that uniquely identifies the base station, comprising the steps of:
