Communication terminal, communication system, control method, and non-transitry computer readable recording medium

A communication system comprising:

• a first transmission terminal configured to transmit a first signal;
• a second transmission terminal configured to transmit a second signal;
• and
• a communication terminal including:
• a reception unit configured to receive the first signal and the second signal;
• a recording unit configured to record a first radio wave intensity representing a radio wave intensity of the first signal and a second radio wave intensity representing a radio wave intensity of the second signal;
• and
• a trigger generation unit configured to generate a first trigger in response to a change from a state of the first radio wave intensity being higher than the second radio wave intensity to a state of the first radio wave intensity being lower than the second radio wave intensity and to generate a second trigger in response to a change from a state of the first radio wave intensity being lower than the second radio wave intensity to a state of the first radio wave intensity being higher than the second radio wave intensity.

A control method comprising:

• receiving a first signal and a second signal;
• recording a first radio wave intensity representing a radio wave intensity of the first signal and a second radio wave intensity representing a radio wave intensity of the second signal;
• and
• generating:
• a first trigger in response to a change from a state of the first radio wave intensity being higher than the second radio wave intensity to a state of the first radio wave intensity being lower than the second radio wave intensity;
• and
• a second trigger in response to a change from a state of the first radio wave intensity being lower than the second radio wave intensity to a state of the first radio wave intensity being higher than the second radio wave intensity.

A non-transitory computer-readable recording medium containing a program causing a computer to perform:

• recording a first radio wave intensity representing a radio wave intensity of a first signal and a second radio wave intensity representing a radio wave intensity of a second signal;
• and
• generating:
• a first trigger in response to a change from a state of the first radio wave intensity being higher than the second radio wave intensity to a state of the first radio wave intensity being lower than the second radio wave intensity;
• and
• a second trigger in response to a change from a state of the first radio wave intensity being lower than the second radio wave intensity to a state of the first radio wave intensity being higher than the second radio wave intensity.
