ABSTRACT:
Regulating the unnecessary handover control count and reducing the power consumption of a radio mobile station thereby reducing the load on an entire radio telecommunications system to maintain stable communications.By adding a position calculator, a direction calculator and a velocity calculator to a radio mobile station and adding the information on a radio base station and the peripheral radio base stations into report information used by the radio base station, handover control considers the position, direction, and velocity as well as the downlink communications quality according to the related art. This regulates the unnecessary handover control count and reduces the load on the entire radio telecommunications system and the power consumption of the radio mobile station.
