Claim 7:
8. A communication terminal comprising:
a cellular communication device configured to perform a cellular communication with base stations; and
at least one processor configured to:
acquire location information indicating a current position of the communication terminal;
cause the cellular communication device to transmit the location information to a communication network;
acquire nearby base station information from the communication network through the cellular communication device, the nearby base station information indicating nearby base stations located in a vicinity of the communication terminal;
measure a receiving level of radio waves from each base station at predetermined intervals and with a predetermined algorithm according to 3GPP standards;
create a list in which the base stations are listed in a decreasing order of the receiving level;
select, as a connection target, the base station having a highest receiving level and attempt to connect to the connection target;
exclude the selected base station from connection candidates when the attempt to connect to the selected base station failed; and
subsequently select, as the connection target, the base station from the nearby base stations in order of proximity to the current position of the communication terminal and attempt to connect to the selected base station.
