PROBLEM TO BE SOLVED: To switch to a suitable next base station in a current location of a radio communication terminal before the radio communication terminal passes a base station between which radio communication is being established, in a radio communication system where a directional antenna of each of base stations has a directivity opposite to a moving direction of the radio communication terminal. SOLUTION: In the radio communication terminal, candidate information determining one or more candidate base stations which are candidates for next radio communication establishment, is stored correspondingly to each base station while the radio communication is being established between the base station. An electric field strength in the radio communication between the base station, between which radio communication is being established currently, is measured (S1) and if the measured electric field strength reaches a preset upper limit threshold value or above (S5: Yes), candidate base stations corresponding to the base station, between which the radio communication is being established currently, are extracted from the candidate information (S8, 9). A base station connectable currently is selected from among the candidate base stations, and switch to the destination between which the radio communication is to be established is conducted (S10).
