In FIG. 2, the control unit 11 of the base station test apparatus 1 according to the present embodiment maintains the name and ID information of the tester who tests the base station test apparatus 1 and the maintenance of the test mobile unit 2. Person's name and its ID information are stored in advance,
A memory 11-2 for storing the date and time of the test maintenance and the result thereof, an I / O I / F 11- for connecting to the test mobile unit 2, the maintenance tool 3, the transmitting / receiving unit 12, the removal key sensor 14, and the alarm unit 15. 3, a PCI I / F 11-4 that can be connected to an external personal computer (PC), a timer 11-5 that generates real-time information, and the control unit 11 and the entire base station test apparatus 1 via these circuits. CP to do
U11-1 and.

In the memory 11-2, a key sensor is used to remove whether the maintenance has been performed from the maintenance tool 3 or the mounting base 13 for the test mobile unit 2 during the test operation has been removed from a predetermined condition. Via 14 and
In the case of an abnormality, the alarm unit 15 stores a monitoring program for issuing an alarm.

Further, a monitoring program is stored for performing the same operation even when the base station test apparatus 1 is in an unmanned state. On the basis of this monitoring program, when an abnormal state occurs, the state is stored in the memory 1 by the CPU 11-1.
It is recorded in 1-2.

FIG. 3 is a flow chart showing the operation of the control unit of the base station test equipment of this embodiment, and FIG. 4 is a schematic diagram showing the operation state of the test equipment of this embodiment. FIG. 3 is a schematic diagram showing a case where the mobile device is fixedly operated in the base station test apparatus, and FIG. 7B is a schematic diagram showing a case where the test mobile device is operated as an ordinary mobile phone.

Next, the operation of the base station test apparatus of this embodiment will be described with reference to FIGS.

When a predetermined maintenance person or tester wants to carry out maintenance or testing using the base station test equipment 1, the maintenance person or tester inputs his or her ID information from the maintenance tool 3 ( S1).

The control unit 11 checks whether the input ID information matches the ID information stored in advance in the internal memory 11-2 (S2). If they do not match, the ID information is sent to the maintenance tool 3. Is not found, a message requesting registration of ID information is sent to the maintenance tool 3 (S3).

When the maintenance tool 3 displays that the ID information matches, the maintainer or the tester inputs a predetermined operation code number of the operation mode desired to be executed, and the operation code number is input to the control unit 11. When it is read (S5) and it is determined that the test mobile unit 2 is in the fixed operation mode in which the test is performed in the state of being fixed to the mounting base 13 (S7), the control unit 11 detects the removal key sensor 14 and It is confirmed that the test mobile unit 2 is not removed from the mounting base 13 and is in a closed state (S7).
It is possible to carry out the test in the state fixed in 3 (S
8) That is, the test can be performed in the state shown in FIG.

When a predetermined test end signal is received from the test mobile unit 2 (S9), the fixed operation mode ends.

In S7, if the removal key sensor 14 detects that the removal key sensor 14 is in the open state due to a malfunction due to an input operation of the key even if the removal key sensor 14 is in the fixed operation mode in S7, it is immediately tested. A command for deleting the ID information and the program stored in the internal memory of the mobile device 2 is sent (S10). As a result,
In the fixed operation mode, it is prevented that the test mobile unit 2 is detached from the mounting base and used illegally.

It should be noted that, in the mounting base 13 of the base station test apparatus 1 of the present embodiment, even if the key state of the detachment key sensor 14 is in the open state, a predetermined period (at least information of the internal memory is (Erased period), mount 1
The test mobile unit 2 cannot be removed from the unit 3.

In S5, when the control unit 11 detects the operation mode of the mobile operation mode in which the test mobile unit 2 is used as an ordinary mobile phone to perform the test (S5, S20),
The removal key sensor 14 is opened, and the test mobile unit 2 is removed from the mounting base 13 to enable the test (S21). Further, it is confirmed that the removal key sensor 14 is normally opened (S22). As a result, as shown in FIG. 4B, the call test can be directly performed from the test mobile device 2 via the base station 4 under test (S2).
3).

After the passing test, the test mobile unit 2 is returned to the mounting base 13, the removal key is closed, and the test end signal is received from the test mobile unit 2 (S24).
1 checks whether the test mobile device 2 is normally attached to the mounting base 13 and the removal key is closed. If all are normal, the test in the portable operation mode ends (S25).

If it is detected in S25 that the key sensor 14 has not returned to the normal state, the control unit 1
Reference numeral 1 alarms the alarm unit 15 to warn the tester to return the test mobile unit 2 to the mounting base 13 normally and close the removal key.

In S5, when the control unit 11 detects the operation mode of the maintenance mode when the maintenance of the test mobile unit 2 is desired (S5, S30), the test mobile unit 2 is detached from the mounting base 13 for maintenance. To
As in the case of the portable operation mode, the removal key sensor 14 is opened to allow maintenance by removing the test mobile unit 2 from the mounting base 13 (S31). Further, it is confirmed that the removal key sensor 14 is normally opened (S3).
2).

When maintenance is carried out (S33), the test mobile unit 2 is returned to the mount 13, the removal key is closed, and a test end signal is received from the test mobile unit 2 (S34), the control unit Reference numeral 11 checks whether or not the test mobile device 2 is normally attached to the mounting base 13 and the removal key is closed. If all are normal, it is considered that the maintenance is completed (S34).

In case of abnormality, the control unit 11 operates in the same manner as in the portable operation mode.

The memory 11-2 of the control unit 11 in the base station test apparatus 1 according to the present embodiment stores who (ID information) who performed the test or maintenance on what day and at what time. , 1 by connecting a personal computer to the PCI I / F 11-4.
You can see the contents of 1-2.

As described above, in the base station test apparatus 1 of this embodiment, the CPU 11 in the control unit 11 is
-1 is the mobile station 2 for testing via the detachment key sensor 14.
The removal from the mounting base 13 is monitored, and especially when the removal in the fixed operation mode is detected, the ID information stored in the memory in the test mobile device 2 or the test is performed before the removal. By erasing the program of the special function, it is possible to prevent the unauthorized leakage of the information of the test mobile unit 2 and the unauthorized use of the test mobile unit 2.
