MOBILE TERMINAL TESTING DEVICE, MOBILE TERMINAL TESTING SYSTEM, AND TESTING METHOD OF NSA

There is provided mobile terminal testing device and system capable of reducing a processing load, when testing mobile terminals that support NSA. Included are a first mobile terminal testing device (1) operating as a base station of LTE and a second mobile terminal testing device (2) operating as a base station of 5G NR of NSA, when testing a mobile terminal which supports NSA, the second mobileterminal testing device generates a control signal of 5G NR, transmits the generated control signal of 5G NR to the first mobile terminal testing device, and the first mobile terminal testing device (1) transmits the received control signal of 5G NR to the mobile terminal (3) according to the LTE. 本发明提供一种对与NSA对应的移动终端进行试验时，能够减轻处理负荷的移动终端试验装置系统。所述移动终端试验装置系统具备：第1移动终端试验装置(1)，作为LTE的基站而进行动作；及第2移动终端试验装置(2)，作为NSA的5G NR的基站而进行动作，对与NSA对应的移动终端进行试验时，第2移动终端试验装置(2)生成5G NR的控制信号，将所生成的5G NR的控制信号发送至第1移动终端试验装置(1)，并将第1移动终端试验装置1接收的5G NR的控制信号通过LTE发送至移动终端(3)。
