A plurality of methods for achieving the soft or softer handoff process such that the performance of a system is improved. A first method is based on delaying the softer handoff process. A second method is based on reducing the power of transmissions from the sector having the weakest signal strength. A third method is based on eliminating transmissions from the sector having the weakest signal strength. A fourth method adds a new base station or sector only when the mobile unit is in need of additional power to operate properly. In all four methods, reverse link demodulation in each sector may continue with or without the transmission of the forward link. In all four methods the operation could be based on the signal strength of the reverse link signal or the forward link. It is also possible to combine two or more of these methods to create a hybrid method.

[ We claim:] [1.] In a spread spectrum communication system in which a mobile user communicates with another user via at least one base station in a system of base stations as directed by a system controller, a method for directing communications between said mobile unit user and said system of base stations comprising the steps of:communicating by said mobile unit with a first base station wherein said first base station has an entry on a first list stored in said mobile unit wherein said first list comprises an entry for each of the one or more base stations in active communication with said mobile unit;measuring at said mobile unit signal strength transmitted by a second base station through which active communication is not established;providing by said mobile unit to said system controller a measured signal strength of said first base station and said measured signal strength of said second base station; andcomparing at said system controller said measured signal strength of said first base station to a desired operating power and sending said mobile unit a new first list comprising said second base station if said measured signal strength of said first base station is less than said desired operating power and said mobile unit is not in communication with any other base station.
