Description

  The present invention relates to a technique for facilitating creation of a remote sequence for remote control from an external computer in a test apparatus for testing a mobile terminal such as a mobile phone or a smartphone.

  A test apparatus for testing a mobile terminal performs communication simulating a base station with a mobile terminal to be tested to establish a call connection state, various measurements relating to the quality of a transmission signal from the mobile terminal, Various tests based on messages exchanged with mobile terminals.

  The mobile terminal test apparatus having such a function is not limited to a local control mode (manual mode) in which a measurer directly operates the operation unit of the test apparatus main body to perform a test, and a predetermined communication interface (for example, GPIB or the like). ) Has a remote control mode in which a test is automatically performed by remote control from an external computer (PC) connected via a computer.

  In the case of the remote control mode, it is necessary for the user to create in advance remote sequence data in which commands for remote control are described in the order of execution, and to send the remote sequence data from the PC to the test apparatus body.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows the configuration of a mobile terminal test apparatus 20 to which the present invention is applied.

  The mobile terminal test apparatus 20 includes a measurement unit 21, a display unit 30, an operation unit 40, an interface 45, and a control unit 50.

  The measurement unit 21 has a function of a pseudo base station apparatus that performs communication simulating a base station with the mobile terminal 1, and includes a data generation unit 22, a transmission unit 23, a coupler 24, a reception unit 25, data The analyzing unit 26 is configured.

  The data generation unit 22 generates a baseband signal including various messages necessary for link connection (call connection) and testing with the mobile terminal 1 by the data generation unit 22 and supplies the baseband signal to the transmission unit 23. The transmission unit 23 performs modulation processing on the input baseband signal in a predetermined modulation format, converts the modulated signal into a frequency band for communication with the mobile terminal 1, and performs the coupler 24. To the mobile terminal 1.

  The receiving unit 25 receives a signal transmitted from the mobile terminal 1 via the coupler 25, performs a frequency conversion process reverse to that of the transmitting unit 23 and a demodulation process to the baseband, and obtains the obtained baseband signal. Is given to the data analysis unit 26.

  The data analysis unit 26 performs an analysis process on a measurement item designated in advance for the obtained baseband signal.

  For example, if the communication method is LTE and the specified measurement item is an occupied bandwidth (Occupied Bandwidth), spectrum analysis processing (fast Fourier transform processing) is performed on the obtained baseband signal, and the spectrum waveform is Obtain the value of the occupied bandwidth.

  If the designated measurement item is a spectrum emission mask, spectrum analysis is performed in the same manner as described above to obtain its spectrum waveform, and it is determined whether or not it is within a predetermined spectrum mask range.

  When the designated measurement item is adjacent channel power (Adjacent Cannel Power), spectrum analysis is extended to the adjacent channel, the spectrum waveform is obtained, and the value of the leakage power to the adjacent channel is obtained.

  In addition, if error vector amplitude (Error vector Magnitude), phase error (Phase Error), amplitude error (Magnitude Error), and symbol point position (Constellation) are specified as measurement items related to modulation quality, the modulation method is used. A vector amplitude error, a phase error, and an amplitude error with respect to a reference symbol point obtained based thereon are obtained.

  In addition to the measurement items related to the quality of the transmission signal of the mobile terminal 1 to be measured as described above, various messages exchanged with the mobile terminal 1 when the signaling test is designated are stored.

  The measurement unit 21 that performs measurement of the measurement items is controlled by information (commands, parameters, etc.) given from the control unit 50, and information obtained by the measurement is given to the control unit 50.

  The display unit 30 is configured by a liquid crystal display panel having a predetermined number of pixels, for example, and the operation unit 40 includes a touch panel type first operation unit 41 that overlaps the screen of the display unit 30, a numeric keypad for numerical input, and a numerical value changing variable. And a second operation unit 42 that requires mechanical operations such as a key pressing operation and a knob rotating operation.

  In the first operation unit 41, transparent electrodes (not shown) for detecting contact with a human finger or the like (which may be either an electrostatic method or a piezoelectric method) are arranged at a fine pitch and touched. Information for specifying the position (touch position information) is output to the control unit 50. The control unit 50 determines which of the touch operation areas set in advance the touch position information belongs, and performs necessary processing for the items assigned to the touch operation area.

  Here, the second operation unit 42 that requires mechanical operation includes a numeric keypad, a rotary encoder, and the like. However, images of the numeric keypad and the rotary encoder are displayed on the screen of the display unit 30, and the first operation corresponding to them is displayed. By setting a touch operation area at the position of the unit 41 and performing a touch operation, it is also possible to input numerical values and change numerical values.

  The interface 45 is used for data communication with the external device (computer) 10, and a well-known GBIB or the like is used for a measurement system or the like.

  The control unit 50 sets various commands and parameters necessary for the test to be performed on the mobile terminal 1 to the measurement unit 21 and controls the display of the measurement result obtained by the measurement unit 21.

  Here, the control unit 50 controls the measurement unit 21 based on an operation on the operation unit 40, and is sent from the external device 10 through the local control mode in which the measurement result is displayed on the display unit 30 and the interface 45. A remote control mode for controlling the measurement unit 21 in accordance with the remote sequence data. In the case of the remote control mode, basically, the measurement result data is sent to the external apparatus side, but may be displayed on the display unit 30 of the test apparatus main body.

  As described above, when the measurement is performed in the remote control mode, the control unit 50 sequentially decodes the commands and parameters described in the remote sequence data sent from the external device, and performs the measurement based on the commands and parameters. Control of the unit 21 is performed.

  In order to facilitate the creation of the remote sequence data, the control unit 50 of the mobile terminal test apparatus 20 of the embodiment is provided with a command explanation storage means 51 and a command explanation display means 52.

  In the command explanation storage means 51, for example, as shown in FIG. 2, remote control corresponding to each operation K1, K2,... .. And command descriptions T1, T2,... In which the command names C1, C2,... And their function descriptions F1, F2,.

  The command explanation display means 52 checks each of the operations defined in the command explanation storage means 51 every time an operation is performed on the operation unit 40 during measurement in the local control mode. A command explanation Ti for remote control corresponding to the operation Ki to be read is read from the command explanation storage means 51 and displayed on the display unit 30.

  Although this display form is arbitrary, as an example, in the local control mode, as shown in FIG. 3, a plurality of buttons B1, B2,. The operator performs a touch operation (indicated by an arrow cursor in the drawing) of the button B2, for example, from a state in which a graph of measurement results regarding a certain measurement item (OBW in this example) is displayed on the right side.

  In response to this operation, the command explanation display means 52 of the control unit 50 examines which of the operations K1, K2,... Stipulated by the command explanation storage means 51 the selection operation for the button B2 corresponds to the button B2. If the selection operation corresponds to, for example, the operation K3, the command explanation T3 corresponding to the operation K3 is read and displayed as a pop-up as shown in FIG. 4, for example.

  From this display, the operator can accurately grasp that the command corresponding to the operation of the button B2 is “C3” and the function usage F3 (command effective range, etc.).

  Therefore, in the local control mode, by confirming the command and function description displayed for each operation on the operation unit 40, it is possible to create remote sequence data corresponding to the procedure of automatic measurement desired by the measurer (text data by the computer). Edit processing) can be performed reliably.

  Note that the command description displayed on the display unit 30 can be erased by touching the button R displayed at the corner of the display area, for example.

  In the above embodiment, the present invention has been applied to a mobile terminal test apparatus that employs a touch panel method, but the present invention can be similarly applied to a mobile terminal test apparatus in which a display unit and an operation unit are independent, Also, the display format of the command explanation is arbitrary regardless of the above embodiment.
