  • Mobile-assisted handoff technique
    Patent number: 5634192
    Abstract: A mobile-assisted handoff technique for a cellular mobile communications system. A mobile makes measurements of adjacent base stations and reports the measurements to the serving base station. The measurements are adjusted to predict signal measurements that the adjacent base stations would make of the mobile. A full set of adjusted measurements, or a combined set of adjusted measurements and true measurements, made by those base stations with locate receivers, may be used in determining the best cell to hand-off the mobile to.
