Radio terminal test apparatus and radio terminal test method

A radio terminal test system that tests radio communication performance of a radio terminal, the system comprising:

• a radio terminal test apparatus including
• a radio signal processing unit that performs measurement processing on a radio signal transmitted from the radio terminal and acquires measurement data,
• a communication control unit that transmits and receives data to and from the radio signal processing unit, and
• a bus that connects the radio signal processing unit and the communication control unit,
• in which the radio signal processing unit includes a division determination unit that determines necessity of division of the measurement data, and, when the division determination unit determines that the measurement data needs to be divided, the measurement data is divided, and divided pieces of the measurement data are division-transmitted a plurality of times from the radio signal processing unit to the communication control unit via the bus;
• a control device that transmits and receives data to and from the communication control unit via a network;
• an anechoic box;
• a positioner that is accommodated in the anechoic box and controls a posture of the radio terminal under control of the control device;
• and
• a test antenna that is accommodated in the anechoic box and performs radio communication with the radio terminal,
• wherein, while the positioner performs entire spherical surface scanning of the radio terminal under control of the control device, the radio signal processing unit measures power of a radio signal radiated from an antenna of the radio terminal via the test antenna.

A radio terminal test method in a radio terminal test apparatus that includes a radio signal processing unit that performs measurement processing on a radio signal transmitted from a radio terminal and acquires measurement data, a communication control unit that transmits and receives data to and from the radio signal processing unit, and a bus that connects the radio signal processing unit and the communication control unit, and tests radio communication performance of the radio terminal, the method comprising:

• a division determination step of determining necessity of division of the measurement data;
• a data division step of, when it is determined in the division determination step that the measurement data needs to be divided, calculating the number of divisions and dividing the measurement data in accordance with the number of divisions;
• and
• a data transmission step of division-transmitting divided pieces of the measurement data from the radio signal processing unit to the communication control unit in a plurality of times via the bus.
