Abstract

A method of enabling a soft handoff in a communication system including a plurality of base stations and at least one mobile station, and base station includes at least one sector. The method includes the steps of: utilizing the base station to group sectors from a list of potential soft handoff sectors to form a soft handoff group; utilizing the mobile station to measure combined pilot signal strength of each soft handoff group; selecting a desired soft handoff group based upon combined pilot signal strength; and updating member sectors in the mobile station's current soft handoff group responsive to the desired soft handoff group.
