Mobile terminal testing apparatus, mobile terminal testing system, and control method for mobile terminal testing apparatus

A mobile terminal testing system comprising:

• a mobile terminal testing apparatus that tests a waveform of a transmission signal transmitted by a mobile terminal;
• and
• a test control apparatus that controls the mobile terminal testing apparatus, wherein
• the mobile terminal testing apparatus has
• a pseudo base station unit that functions as a base station for the mobile terminal, changes power of the transmission signal transmitted by the mobile terminal in a first range so as to have a first off period, an on period, and a second off period, and further changes the power of the transmission signal transmitted by the mobile terminal in a second range lower than the first range so as to have the first off period, the on period, and the second off period,
• the test control apparatus has
• a test control unit that controls the pseudo base station unit, and
• the test control unit
• executes first measurement to measure the power of the transmission signal, changed in the first range, received by the pseudo base station unit,
• executes second measurement to measure the power of the transmission signal, changed in the second range, received by the pseudo base station unit,
• determines a first threshold and a second threshold, based on a measurement result measured in the second measurement,
• specifies a first measurement period until the measurement result of the second measurement reaches the first threshold from the start of the first off period to the end of the on period,
• specifies a second measurement period until the measurement result of the second measurement reaches the second threshold from the end of the second off period to the start of the on period, and
• determines, as a test result, a measurement result measured in the second measurement in the first measurement period and the second measurement period, and a measurement result measured in the first measurement in a third measurement period between the first measurement period and the second measurement period.

A control method for a mobile terminal testing apparatus which includes

• a pseudo base station unit that functions as a base station for a mobile terminal, and
• a test control unit that controls the pseudo base station unit, and
• tests a waveform of a transmission signal transmitted by the mobile terminal, the control method causing the test control unit to execute:
• a first measurement execution step of controlling the pseudo base station unit such that power of a transmission signal transmitted by the mobile terminal changes in a first range so as to have a first off period, an on period, and a second off period, and executing first measurement to measure the power of the transmission signal received by the pseudo base station unit;
• a second measurement execution step of controlling the pseudo base station unit such that power of the transmission signal transmitted by the mobile terminal changes in a second range lower than the first range so as to have the first off period, the on period, and the second off period, and executing second measurement to measure the power of the transmission signal received by the pseudo base station unit;
• a threshold determination step of determining a first threshold and a second threshold, based on a measurement result measured in the second measurement;
• a first measurement period specifying step of specifying a first measurement period until the measurement result of the second measurement reaches the first threshold from the start of the first off period to the end of the on period;
• a second measurement period specifying step of specifying a second measurement period until the measurement result of the second measurement reaches the second threshold from the end of the second off period to the start of the on period;
• and
• a test result determining step of determining, as a test result, a measurement result measured in the second measurement in the first measurement period and the second measurement period, and a measurement result measured in the first measurement in a third measurement period between the first measurement period and the second measurement period.
