Wireless communication terminal and wireless communication system

A wireless communication terminal enabling connection with a plurality of base stations disposed in different positions, the wireless communication terminal comprising:

• a base station scanning unit scanning and detecting a base station capable of communication at a current position of the wireless communication terminal,
• a simultaneous detection base station recording unit recording a simultaneously detected base station as simultaneous detection information in a storage unit,
• a connection candidate extraction unit wherein the simultaneous detection information forms a basis for extraction of a base station which can be detected simultaneously with a connected base station which is currently connected, and
• a first communication unit performing communication by connection with the extracted connection candidate base station,
• wherein the simultaneous detection base station recording unit is configured to record simultaneous detection information including a predetermined communication parameter value related to a base station together with the simultaneously detected base station, and
• the wireless communication terminal includes:
• a calculation processing unit calculating a probability of detecting a connection candidate base station simultaneously with a connected base station or a detected base station, the probability calculated as a simultaneous detection probability by a predetermined calculation using the predetermined communication parameter value, and
• a connection candidate selection unit selecting a connection candidate base station for which the simultaneous detection probability satisfies a predetermined condition, and
• the first communication unit performs communication by connection with the selected connection candidate base station,
• wherein a radio-wave intensity with each base station is used as the predetermined communication parameter value, the radio-wave intensity of each simultaneously detected base station is accumulated in the simultaneous detection information, and the simultaneous detection probability is a value calculated by dividing a cumulative value for the simultaneous detection of the connected base station or the detected base station, together with the connection candidate base station, by the detection frequency for the connected base station or the detected base station.
