A method and apparatus for providing soft handoff in a mobile communication system. In current systems is that the members of active set are determined in accordance with comparisons of measured pilot energy with fixed thresholds. However, the value of providing a redundant communication link to a mobile station depends strongly on the energy of other signals being provided to the mobile station. In the present invention, the signal strengths of other base stations in communication with a mobile station are considered when determining whether adding a base to that set of base stations in communication with the remote station is of sufficient value to justify the impact on system capacity.

[ We claim:] [6.] A method for determining the base stations to transmit to a remote station at said remote station in which a plurality of base stations comprising an Active Set of base stations transmit to said remote station and wherein a second set of base stations which are not members of said Active Set comprise a Candidate Set of base stations, said method comprising the steps of:aggregating signal energies of said Active Set of base stations;generating a threshold value in accordance with said aggregated signal energies of said base station members of said Active Set;comparing signal energy of a base station of said Candidate Set of base stations with said threshold; andadding said base station of said Candidate Set of base stations to said Active Set of base stations when said signal energy of a base station of said Candidate Set of base stations exceeds said threshold.
