Patent ID: 6937583

Claim:
A method of controlling forward link power during intergenerational soft handoff (“ISHO”) procedures in a wireless communication system, wherein the wireless communication system includes a plurality of base stations in communication with at least one mobile station, wherein the base stations transmit information to the at least one mobile station via a forward link, and wherein the base stations receive information from the at least one mobile station via a reverse link, and wherein each base station is in communication with a mobile station controller (MSC), and wherein a selected mobile station is handed off from a serving communication system to a target communication system, and wherein the serving and target systems comprise different generational CDMA communication systems, comprising the steps of: a) determining a forward link transmit power of a serving communication system; b) calculating a forward link transmit power of a target system, including subtracting an ISHO offset from the forward link transmit power of the serving communication system determined during step (a); and c) controlling the forward link transmit power of the target system based upon the forward link transmit power calculated during step (b).
