A mobile station assists the wireless network with handover from a first base station to a second base station. The mobile station receives transmissions from the first base station using a first spreading code corresponding to the first base station while receiving signals from at least one other base station. The mobile station determines the relative signal strengths of the signals received from the other base stations and reports the relative signal strengths to the first base station to support handover determinations by the wireless network.

Mobile assisted handover using CDMA

A method and system for facilitating handover in mobile radio communication systems are illustrated. The mobile unit assists in making handover decisions by monitoring the signal strength of control channels transmitted by base stations in neighboring cells. During the handover, the mobile station can receive the same information from and/or transmit the same information to a plurality of base stations to provide diversity combination and improve transmission quality.
