Abstract

PROBLEM TO BE SOLVED: To remove effect of a leaked radio wave or a sneak path of a radio wave by executing test transmission from a transmitter within a test transmission station and receiving it by a testing receiver within a test reception station so as to obtain an actually radio-propagated result as a test result. SOLUTION: This system consists of a test transmission station 11 and a test receiving station 12 respectively provided with a base station host equipment 1 instructing the transmission and reception of a testing radio wave to a base station, a base station controller 2 controlling the base station, a transmitter and receiver 3 transmitting a testing radio wave and a testing receiver 4 receiving the testing radio wave. The start of a test is decided by the host device of the base station 1 and test reception is instructed to the station 12. After then, test transmission is instructed to the station 11. During the execution of the test, the host device 1 waits for a report from the station 12. When the result of the test is reported, the analyzing of the testing result is started but when the result is not reported, test transmission is abnormally finished.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a test method for a wireless network having a plurality of base stations.

[0002]

2. Description of the Related Art As a conventional test system of this kind, for example, Japanese Patent Application Laid-Open No. Hei 5-111070 provides a mobile radio transceiver test system which can reduce the size of the apparatus and facilitate the operation test of the mobile radio transceiver. For this purpose, a system as shown in FIG. 4 has been proposed. Referring to FIG. 4, this conventional wireless network test method uses a test control device 2
1. The radio wave including the operation test information signal supplied through the radio base station controller 22 and the line 23 is transmitted to the radio base station 25.
And transmits this radio wave to the adjacent service area 29,
The test control device 21 receives and transmits between the mobile radio transceivers 27 and 28 in the base station 30 and determines whether or not the operation test information signal transmitted from the radio base station 26 that has received the transmission radio wave has been returned normally. Service area 29, 3
The operation test of the mobile radio transceivers 27 and 28 within 0 is performed.

[0003]

The above-mentioned conventional test method originally performs an operation test of a mobile radio transceiver, and performs a test by combining a radio base station and a mobile radio transceiver. There is a problem that the failure of the radio base station itself cannot be determined.

Further, in the above-described conventional test method, for example, in a sectorized base station, even if a certain sector fails, the base station can receive a test signal. have. This is because, since the mobile radio transceiver is used, another sector performs a receiving operation due to the wraparound radio wave.

[0005] In the test method of the radio base station,
Conventionally, transmission / reception was performed by a test transceiver provided in its own base station, and the presence or absence of a failure in the radio base station was confirmed. Therefore, even if there is an obstacle in the actual radio wave propagation, there is a problem that the reception is possible due to the leakage current or the sneak path, and the obstacle cannot be determined.

Accordingly, the present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to sufficiently reduce radio waves transmitted from a transmitting base station in a transmission / reception test of a radio base station. Another object of the present invention is to provide a wireless network test method that enables a test to be performed in a state similar to an actual operation by receiving a signal at another remote base station, thereby improving the reliability of the test result.

[0007]

In order to achieve the above object, a wireless network test system according to the present invention includes means for performing transmission and reception between a transmitter in a test transmitting station and a test receiver in a test receiving station for testing. It is characterized by.

In the present invention, test transmission is performed from the transmitter in the test transmitting station, and reception is performed by the test receiver in the test receiving station. Therefore, the result of actual radio wave propagation is
Since it is obtained as a test result, it is possible to eliminate the influence of leaked radio waves and wraparound radio waves.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an embodiment of the present invention.

Referring to FIG. 1, an embodiment of the present invention includes a base station host apparatus 1 for instructing a base station to transmit and receive test radio waves, a base station control apparatus 2 for controlling the base station, It comprises a transmitter / receiver 3 for transmitting radio waves, a test transmitting station 11 provided with a test receiver 4 for receiving test radio waves, and a test receiving station 12.

Next, the operation of the embodiment of the present invention will be described in detail with reference to FIG.

The start of the test is determined by the base station host device 1 (step S10), and a test reception is instructed to the test receiving station 12 (step S20). Thereafter, a test transmission is instructed to the test transmitting station 11 (step S3).
0).

While the test is being performed, the base station host device 1
Are waiting for a report from the test receiving station 12 (step S
40).

When there is a report of the test result (step S
50), the process proceeds to the next test result analysis (step S60), but if there is no report of the result, the process ends abnormally.

If the test result analysis is normal (step S6)
0), the process proceeds to the process of determining whether or not to continue the test (step S70). If the test is to be continued, the process returns to step 10. If not, the process ends normally.

In order to explain the above embodiment of the present invention with a more specific example, the embodiment of the present invention will be described with reference to FIG.
This will be described with reference to FIG.

As shown in FIG. 3, around the test transmitting station 11, there are a plurality of stations such as test receiving stations 12, 13, and 14.
All are connected to the base station host device 1. The base station host device 1 includes a test transmitting station 11 and a test receiving station 1 around the test transmitting station 11.
Select 2, 13, and 14 and test in order. The test items may be arbitrarily determined between the test transmitting station and the test receiving station under the control of the base station host device 1 in addition to the various standards.

If there is a failure in the sector antenna b of the test transmitting station 11, the test with the test receiving stations 12 and 14 ends normally, but the test with the test receiving station 13 does not end normally. , Can find obstacles.

[0019]

As described above, according to the present invention,
By separating the test transmitting station and the test receiving station and actually obtaining the test results of radio wave propagation, it is possible to eliminate the influence of leaked radio waves and wraparound radio waves.
