Abstract:
1. A radio communication method using: a first radio base station; and a second radio base station located adjacent to the first radio base station and including an adaptive array antenna for radiating a dynamic directional beam, the method comprising the steps of: acquiring moving speed of a radio communication terminal located in a cell formed by the first radio base station; requesting the second radio base station to radiate the directional beam in a direction of the cell formed by the first radio base station, when the moving speed is equal to or more than a predetermined threshold, wherein when the moving speed is equal to or more than the predetermined threshold, a plurality of the second radio base stations are requested to radiate the directional beams in direction of the cell formed by the first radio base station; accommodating the radio communication terminal in the second radio base station that has transmitted the directional beam in response to the request; wherein the radio communication terminal is accommodated in one of the second radio base stations that have radiated the directional beams in response to the request; acquiring a list including identification information of the plurality of second radio base stations that have transmitted the directional beams; and selecting the second radio base station in which the radio communication terminal is to be accommodated, on the basis of the list, wherein the list includes at least one piece of information of a cell radius of the second radio base station, a frequency band of the second radio base station, and an area section indicating an area in which the second radio base station is located.
