PROBLEM TO BE SOLVED: To rightly perform power measurement of a mobile terminal that is adaptive to a dual carrier system.SOLUTION: A message for outputting a signal of a first carrier is sent out, a reception signal is monitored while setting a state where the signal of the first carrier outputted from the mobile terminal can be received, and power after the lapse of a predetermined time from the timing in which a shift amount of power of the reception signal exceeds a trigger level, is detected as power of the signal of the first carrier. Next, a message for reducing transmission power is sent out such that a leakage component included in a signal band of a second carrier, in a signal component of the first carrier, ranges not to exceed the trigger level, and after transmission power is reduced, a message for outputting a signal of the second carrier is sent out. A reception signal is monitored while setting a state where the signal of the second carrier can be received, and power after the lapse of a predetermined time from the timing in which a shift amount of the power of the reception signal exceeds the trigger level, is detected as power of the signal of the second carrier.SELECTED DRAWING: Figure 1 |
