Cellular network handoff decision mechanism

摘要

Disclosed is a cellular network handoff decision mechanism which comprising the steps of: determining a sampling interval using a carrier wavelength; determining a local averaging interval that is larger than the sampling interval; determining a handoff decision interval that is larger than the local averaging interval; selecting at least two base stations from a multitude of base stations having a pilot signal from a reference cellular network using a selection criterion; determining a received signal strength from the pilot signal strength for each of the selected base stations once during every sampling interval; calculating a local average signal strength value using each of the received signal strengths once during every local averaging interval; determining an assignment region in which the local average signal strength value lies using a hysteresis range; and calculating a handoff decision once during every handoff decision interval using a handoff calculation.
