Recommendation H. The audio data is 3G-AMR (3rd Generation Adaptive Multi Rate) or ITU-T recommendation G.264. This format uses 723.1. In other communication protocols, data in a predetermined data format used for voice, image, etc. defined in each standard is used as media information.

  The sound input from the microphone 22 b and the image taken by the camera 22 c are converted into media information by the media input / output device 22 and passed to the media information conversion unit 21. Further, the media input / output device 22 outputs the media information received from the media information conversion unit 21 as sound to the speaker 22a and displays it as a video on the display device 22d.

  A media information conversion unit 21 performs mutual conversion between transmission / reception data and media information according to a communication format format using a predetermined communication protocol performed between the mobile communication terminal 2 and the pseudo base station unit 10. In a videophone call or the like, media information is cut out from the received data received from the mobile communication terminal 2 by the media information conversion unit 21 and output to the media input / output device 22. Since the media information has a format such as the above-described MPEG-4 or 3G-AMR, the media input / output device 22 converts the media information into actual audio data and actual image data, and outputs it through the speaker 22a and the display device 22d. The media information conversion unit 21 may perform conversion into actual audio data or actual image data.

The media information passed from the media input / output device 22 is converted into transmission data in accordance with a communication format format of a predetermined communication protocol by the media information conversion unit 21 and transmitted to the mobile communication terminal 2 through the pseudo base station unit 10. The conversion from the input voice or image into the format such as MPEG-4 or 3G-AMR may be performed by the media information conversion unit 21 instead of the media input / output device 22.

  Through the operation of the media information conversion unit 21 described above, the virtual mobile phone realized by the virtual terminal unit 20 and the mobile communication terminal 2 can face each other and make a call.

  Also, information related to communication control received by the media information conversion unit 21 from the pseudo base station unit 10 is passed to the virtual terminal control unit 24 as received communication control information without being converted into media information. The virtual terminal control unit 24 sends a response to the reception communication control information as transmission communication control information to the pseudo base station unit 10 through the media information conversion unit 21 according to the operation procedure described in the second scenario 32. Through this process, the virtual terminal unit 20 establishes communication with the pseudo base station unit 10 to enable a call.

The media input / output device 22 performs processing for converting voice, image, and the like input to the media input / output device 22 as media information into predetermined storable data defined in the communication protocol to be used. It may be performed by the unit 21 or the virtual terminal control unit 24.

  Further, it can be stored in the transmission media information storage unit 26 from the external device (for example, PC) connected to the control interface unit 40 through the virtual terminal control unit 24.

  Received data received by the pseudo base station unit 10 from the mobile communication terminal 2 using a predetermined communication protocol is converted into media information by the media information conversion unit 21 and stored in the received media information storage unit 25 through the virtual terminal control unit 24.

  The information stored in the received media information storage unit 25 from the received media information may be specified by describing in the second scenario 32, or the storage start time and storage time specified from the operation device 23. Alternatively, it is possible to set conditions for detecting specific data from received data and storing media information.

  The media information stored in the received media information storage unit 25 can also be displayed on the display device 22 d of the media input / output device 22 through the virtual terminal control unit 24. Further, it can be output as digital data to an external device (for example, a PC) connected to the control interface unit 40.

  In response to an instruction from the virtual terminal control unit 24, the information quality determination unit 27 determines the quality of the media information stored in the received media information storage unit 25. Judgment can be made quantitatively using a statistical method (for example, Poisson distribution or binomial distribution) based on the frequency of occurrence of bit error detection, bit loss, etc., and numerical analysis (for example, ITU for voice quality). -T recommendation P.861 (Perceptual Speech Quality Measurement) etc. can also be used to evaluate audio quality and image quality.

  In addition, when the mobile communication terminal 2 has a function of returning received data as transmission data, the transmission media information storage unit 26 and the reception media information storage unit 25 are linked to each other and stored in the transmission media information storage unit 26 in advance. The media information is transmitted to the mobile test terminal 2, returned by the mobile test terminal 2, and the media information received by the virtual terminal unit 20 is stored in the received media information storage unit 25. The information quality judgment unit 27 reads the content stored in the transmission media information storage unit 26 through the virtual terminal control unit 24 and compares it with the media information stored in the reception media information storage unit 25, thereby communicating in the entire transmission / reception system. Enables performance tests and evaluations such as the degree of deterioration and quality of the above data.

  The information quality determination result of the media information is displayed on the display device 22d as the information quality determination result by the information quality determination unit 27 through the virtual terminal control unit 24. The information quality determination result displayed on the display device 22d can also be output as digital data to an external device (for example, a PC) connected to the control interface unit 40.

(Example 5)
