摘要： PROBLEM TO BE SOLVED: To provide a radio communication terminal and radio communication system for maintaining seamless high-capacity communication by properly acquiring a Doppler shift frequency in consideration of individual difference of the radio communication terminal or each of base stations, and by switching a base station for establishing radio communication in accordance with a positional relation between the radio communication terminal and each of the base stations specified by the Doppler shift frequency. SOLUTION: A connection destination designating part 53 determines whether each of the base stations is located ahead of the radio communication terminal Y or behind the radio communication terminal Y, on the basis of a Doppler shift frequency obtained by subtracting the communication frequency of a table D1 for stop, which is detected by a frequency detecting part 421 during the stop of the radio communication terminal Y and stored in advance, from a communication frequency of a table D2 for move, which is detected by the frequency detecting part 421 while the radio communication terminal Y moves, and establishes radio communication with one base station determined to be located ahead of the radio communication terminal Y.

摘要： 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).
