The signal information storage server 22 collects information on signals handled by the commercial stations 10 to 20 and collects information on signals generated by the pseudo stations 10a to 20a. Based on the difference, the commercial station information is converted into a format that can be handled by the pseudo station and transmitted to the pseudo signal generating device 24, and is configured as shown in FIG.
[0022]
That is, a transmission / reception unit 30, a first signal distribution unit 32, a first storage unit 34, a second storage unit 36, a signal conversion unit 38, and a second signal distribution unit 40 are provided. Configured.
The transmission / reception unit 30 receives the intra-station signals x1 to x6 and the inter-station signals y1 to y6 from the commercial stations 10 to 20 and outputs them to the first signal distribution unit 32, and the intra-station signals x1 to x6 and A signal obtained by converting the inter-station signals y1 to y6 into a format that can be handled by the pseudo station 26 is transmitted to the pseudo signal generation device 24 (first and second pseudo signal generation devices 24a and 24b).
[0023]
The first signal distribution unit 32 distributes and outputs the intra-station signals x1 to x6 received by the transmission / reception unit 30 to the first storage unit 34 and the inter-station signals y1 to y6 to the second storage unit 36. It is.

[0026]
These pseudo stations 10 a to 20 a execute the operation status in each commercial station 10 to 20 in a pseudo manner based on the pseudo signal generated by the pseudo signal generation device 24 and the signal in the conversion station from the server 22. Thus, the operation status of each commercial station 10-20 is automatically reproduced.
That is, each of the pseudo stations 10a to 20a actually receives a pseudo signal similar to the signal transmitted from one or more other commercial stations to the local commercial station from the pseudo signal generation device 24 as described above. It is possible to reproduce an operation situation similar to the operation situation in which the commercial stations 10 to 20 exchange signals with each other.
[0027]
In addition, if each of the pseudo stations 10a to 20a has the same function as each of the commercial stations 10 to 20, it is possible to generate an internal signal when each of the commercial stations 10 to 20 is operating alone. It only becomes. However, by using the pseudo signal from the pseudo signal generation device 24 as described above, it is possible to take into account the influence of signal exchange with other stations, so the actual operation status of each commercial station 10-20 is reproduced. It is possible to do that.
[0028]
Next, the operation of the communication test process by the communication test system having such a configuration will be described with reference to the flowchart shown in FIG.

[0029]
First, in step S1, the intra-station signal x5 from the mobile gateway station 18 and inter-station signals y4 and y6 from the mobile switching center 16 and the signal relay station 20 are received by the transmission / reception unit 30 of the server 22.
In step S2, the received signal is output by the first signal distribution unit 32 so that the intra-station signal x5 is output to the first storage unit 34 and the inter-station signals y4 and y6 are output to the second storage unit 36. Sorted.
[0030]
In step S3, the allocated intra-station signal x5 and inter-station signals y4, y6 are stored in the first storage unit 34, and the inter-station signals y4, y6 are stored in the second storage unit 36. The
The stored intra-station signals x1 to x6 and inter-station signals y4 and y6 are read out by the signal conversion unit 38 and converted into a format that can be handled by the simulated mobile gateway station 18a in step S4.
[0031]
In step S5, these converted signals are transmitted to the pseudo mobile gateway station 18a via the transmitter / receiver 30 by the distribution control of the second signal distribution unit 40, and the inter-conversion station signal y4a. Is transmitted to the first pseudo signal generation device 24a via the transmission / reception unit 30, and the inter-converting station signal y6a is transmitted to the second pseudo signal generation device 24b via the transmission / reception unit 30.
[0032]
In step S6, the first and second pseudo signal generation devices 24a and 24b generate each pseudo signal according to each of the inter-station signals y4 and y6, and output the pseudo signal to the pseudo mobile gateway station 18a.
In step S7, the simulated mobile gateway station 18a reproduces the operation status in the mobile gateway station 18 on the basis of the simulated signals and the in-station signal x5 from the server 22. Through this reproduction, information related to the occurrence of a failure can be acquired.
[0033]
As described above, according to the communication test system of the present embodiment, the intra-station signals x1 to x6 operated by the commercial stations 10 to 20 themselves constituting the mobile communication network and the transmission between the commercial stations 10 to 20 are transmitted. The inter-station signals y1 to y6 to be received are received by the server 22. Further, the server 22 converts the received intra-station signals x1 to x6 and inter-station signals y1 to y6 into a format that can be handled by the pseudo stations 10a to 20a having the same functions as the commercial stations 10 to 20. In addition, a signal transmitted from one or more other stations connected to a certain target station to the target station among the commercial stations 10 to 20 by the pseudo signal generation device 24 is converted between the stations converted by the server 22. It is generated pseudo according to the signal. Then, in each of the pseudo stations 10a to 20a, the operation status of each of the commercial stations 10 to 20 is determined based on the pseudo signal generated by the pseudo signal generation device 24 and the in-station signal converted by the server 22. It was reproduced in a pseudo manner.
[0034]
That is, when each of the pseudo stations 10a to 20a reproduces the actual operation status of each of the commercial stations 10 to 20, it is transmitted from one or more other stations connected to the target station to be reproduced to the target station. Are generated in accordance with the inter-station signal converted by the server 22. By using the pseudo signal, the pseudo station having the same function as the target station can take into account the effect of signal exchange with other stations, so that the actual operation status of the target station is reproduced. It becomes possible.
[0035]
Accordingly, it is possible to automatically reproduce the operation status when a failure occurs in the communication system. Due to this reproduction, information related to the occurrence of a failure can be immediately acquired and analyzed, so that the failure of the communication system can be solved at an early stage.
Further, since the intra-station signals x1 to x6 and the inter-station signals y1 to y6 received from the commercial stations 10 to 20 can be stored in the server 22, it is possible to analyze a failure occurring in the mobile communication network. The signal related to the failure can be repeatedly read out and used for the analysis.
[0036]

In addition, a signal to be transmitted to the target station from one or a plurality of other stations connected to a certain target station among the stations is generated in a pseudo manner according to the previously converted inter-station signal. Based on the generated pseudo signal and the previously converted in-station signal, the operation status of various stations in the communication network is simulated.
[0037]
That is, when the simulated station reproduces the actual operation status of the station, the signal transmitted from one or more other stations connected to the target station to be reproduced to the target station is converted by the server. It is generated in a pseudo manner according to the inter-station signal. By using the pseudo signal, the pseudo station having the same function as the target station can take into account the effect of signal exchange with other stations, so that the actual operation status of the target station is reproduced.
