Abstract

Provided are a mobile terminal testing apparatus, a mobile terminal testing system, and a control method for a mobile terminal testing apparatus which can prevent the level of the multiplexed signal transmitted and received to and from a mobile terminal from being misidentified. Provided is a mobile terminal testing apparatus which tests a waveform of a multiplexed signal obtained by multiplexing a uplink signal transmitted by a mobile terminal and a downlink signal transmitted to the mobile terminal by time division multiplexing, in which area information 21 of a first display mode indicating the uplink signal and area information 22 of a second display mode indicating the downlink signal are displayed in association with the waveform 23 of the multiplexed signal, on the display unit.

First claim

What is claimed is:

1. A mobile terminal testing apparatus configured to test a waveform of a multiplexed signal obtained by multiplexing an uplink signal transmitted by a mobile terminal and a downlink signal transmitted to the mobile terminal by time division multiplexing, comprising:
a pseudo base station configured to function as a base station for the mobile terminal;
a test controller configured to control the pseudo base station; and
a display configured to display the waveform of the multiplexed signal,
wherein the test controller is configured to display the uplink signal with an uplink period indication indicating a time period of the uplink signal and the downlink signal with a downlink period indication indicating a time period of the downlink signal on the display such that the uplink and downlink signals are identifiable with the uplink and downlink period indications on the display,
wherein the test controller is configured to display area information for identifying a time domain corresponding to the uplink signal and area information for identifying a time domain corresponding to the downlink signal in different color schemes such that the uplink signal and the downlink signal are distinguishably displayed in association with the waveform of the multiplexed signal, on the display.

2. A mobile terminal testing system comprising:
a mobile terminal testing apparatus configured to test a waveform of a multiplexed signal obtained by multiplexing an uplink signal transmitted by a mobile terminal and a downlink signal transmitted to the mobile terminal by time division multiplexing; and
a test controller configured to control the mobile terminal testing apparatus,
wherein the mobile terminal testing apparatus comprises a pseudo base station that functions as a base station for the mobile terminal,
wherein the test control apparatus comprises:
a test controller configured to control the pseudo base station unit, and
a display configured to display the waveform of the multiplexed signal, and

wherein the test controller is configured to display the uplink signal with an uplink period indication indicating a time period of the uplink signal and the downlink signal with a downlink period indication indicating a time period of the downlink signal on the display such that the uplink and downlink signals are identifiable with the uplink and downlink period indications on the display,
wherein the test controller is configured to display area information for identifying a time domain corresponding to the uplink signal and area information for identifying a time domain corresponding to the downlink signal in different color schemes such that the uplink signal and the downlink signal are distinguishably displayed in association with the waveform of the multiplexed signal, on the display.

3. A control method for a mobile terminal testing apparatus which comprises:
a pseudo base station configured to function as a base station for a mobile terminal,
a test controller configured to control the pseudo base station, and
a display configured to display a waveform of a multiplexed signal obtained by multiplexing an uplink signal transmitted by the mobile terminal and a downlink signal transmitted to the mobile terminal by time division multiplexing,
the method comprising:
testing the waveform of the multiplexed signal; and
displaying the uplink signal with an uplink period indication indicating a time period of the uplink signal and the downlink signal with a downlink period indication indicating a time period of the downlink signal on the display such that the uplink and downlink signals are identifiable with the uplink and downlink period indications on the display, the displaying be caused by the test controller,
wherein the test controller is configured to display area information for identifying a time domain corresponding to the uplink signal and area information for identifying a time domain corresponding to the downlink signal in different color schemes such that the uplink signal and the downlink signal are distinguishably displayed in association with the waveform of the multiplexed signal, on the display.
