Abstract :
An autonomous learning procedure fir cell boundaries is reported, and advanced handoff controls making use of the learned cell boundary are proposed. The cell boundary is learned by moving a mobile set, which has a detector showing equal signal strength along the boundary, after all the base stations have been installed. Handoff control using reliable cell boundaries can omit the exceptional transactions caused by multipath fading. Advanced controls, soft handoff without intermittence, and its extension by means of fuzzy decisions are described
