  • Publication number: 20230362690
    Abstract: There is provided a mobile terminal test apparatus capable of efficiently performing a test by collectively processing control messages. There is included a control unit 6 that switches, as a mode for transmitting a control message to a mobile terminal 10, between an Automatic mode in which by a setting of a parameter by a user, the control message is transmitted to the mobile terminal 10 when it becomes necessary to transmit the control message to the mobile terminal 10, and a Manual mode in which change information on the parameter by the setting of the parameter by the user is held, and the control message corresponding to the held change information is transmitted to the mobile terminal 10 when a parameter application instruction is given by the user.

  • Patent number: 11799566
    Abstract: To provide a mobile terminal test device capable of performing a test with high efficiency by automatically setting a Band filter. A mobile terminal test device includes a simulated base station unit 2 that performs 5G NR communication with a mobile terminal 10 in accordance with the 5G NR standard, a scenario processing unit 3 that reads a stored scenario and causes the simulated base station unit 2 to transmit notification information or execute a communication sequence with the mobile terminal 10, based on the scenario, and a control unit 6 that, when being connected to the mobile terminal 10, sets, as a Band filter, a band set as a communicable frequency band and transmits the set band to the mobile terminal 10.
