Next, an embodiment of the present invention will be described with reference to the drawings. In each of the drawings referred to in the following description, parts equivalent to those in other drawings are indicated by the same reference numerals.
FIG. 1 is a block diagram showing a configuration of the communication processing apparatus automatic test system according to the present embodiment.

The operation communication processing device 9 is a device configuring the network N, and includes, for example, an exchange and an HLR (home location register) used in a mobile communication network. In the present invention, a communication processing device which is actually operated on the network N and which is arbitrarily specified from a plurality of communication processing devices is used. The network N includes, for example, a mobile communication network and a fixed telephone network.
[0020]
The test support device 1 is a device for supporting a test performed to determine whether a program or the like developed for a communication processing device operates normally. The test support device 1 is connected to the operation communication processing device 9 via the signal line L1, and receives a signal input / output to / from the operation communication processing device 9. Arrows of the signal lines L1 to L14 in the drawing indicate directions in which signals are transmitted. Based on the input / output signal, the pseudo call device 7 generates a command for injecting a pseudo call similar to the call issued to the specific communication processing device 9 into the communication processing device 8 to be tested.
[0021]
The test support apparatus 1 is also communicable with the pseudo call device 7 via the signal lines L6 and L9, and sends out the generated command to the pseudo call device 7. Further, the result of the processing performed by the test target communication processing device 8 by sending the command is transmitted to the test support device 1 via the pseudo call device 7. The test support apparatus 1 compares the result of the processing by the test target communication processing device 8 with the result of the processing by the operation communication processing device 9 to determine the normality of the test target communication processing device 8. The detailed configuration and operation of the test support device 1 will be described later.
[0022]
The pseudo call device 7 is connected to the test support device 1 and the test target communication processing device 8 to be tested via signal lines L6 and L9, and is capable of communicating with each device. On the basis of a command received from the test support apparatus 1, a pseudo call to the test target communication processing apparatus 8 to be tested is generated and input. The result of the processing performed by the test target communication processing device 8 to be tested based on the incoming call is received from the test target communication processing device 8 and transmitted to the test support device 1.
[0023]
The test target communication processing device 8 is a communication processing device to be tested, and is a communication processing device such as an exchange that is operated in the above-described network N after the test.

And is configured.
[0024]
Hereinafter, the detailed operation of the test support apparatus 1 by these units will be described using the block diagram of FIG. 1 and the flowchart of FIG.
In step S201, the transceiver 21 receives an input / output signal being processed in the operation communication processing device 9 for a certain period. The input signal corresponds to a call issued to the active communication processing device 9 in the network N, and the output signal corresponds to a result of processing performed by the active communication processing device 9 on the call.
[0025]
In step S202, the distribution function unit 22 extracts an input signal from the input / output signal transferred by the transceiver 21. The extracted input signal is transferred to the conversion function unit 23. Further, the distribution function unit 22 stores the input / output signals in the storage medium 31 for holding data relating to the operation communication processing device 9.
In step S203, the conversion function unit 23 generates a command to be sent to the pseudo call device 7 based on the input signal transferred from the distribution function unit 22 in step S202. As described above, this command is a command for injecting a pseudo call similar to the call issued to the operation communication processing device 9 by the pseudo call device 7 to the communication processing device 8 to be tested. The generation of the command based on the input signal is performed using, for example, a correspondence table between the input signal and the command. That is, for example, a case may be considered in which an off-hook signal transmitted from a communication terminal connected to the exchange is extracted from a group of input signals of the exchange actually operated in the network, and this command is generated. In this case, using the correspondence table, it is possible to specify the "command for transmitting the off-hook signal to the exchange to be tested by the pseudo call device" corresponding to the "off-hook input signal". .
[0026]
The conversion function unit 23 stores the generated command in the storage medium 32.
In step S204, the command generated in step S203 is transmitted to pseudo call device 7 via transceiver 21.
As a result, a pseudo call is input from the pseudo call device 7 to the communication processing device 8 to be tested, and the processing is performed in the communication processing device 8 to be tested.
[0027]
In step S205, the result of the processing by the communication processing device under test 8 is returned to the test support device 1 via the pseudo call device 7. The result of the process received by the transceiver 21 of the test support apparatus 1 is transferred to the conversion function unit 23.
In step S206, the conversion function unit 23 converts the returned processing result of the communication processing device 8 under test into a format of an output signal of the communication processing device 8 under test, and stores the converted signal via the signal line L12. It is stored in the medium 32. In this way, by converting to the format of the output signal, it is possible to compare with the output signal acquired from the operation communication processing device 9 as described later. At the same time, the conversion function unit 23 transmits an instruction signal to the comparison function unit 24 via the signal line L11 so as to perform a comparison process based on the converted output signal.
[0028]
In step S207, the comparison function unit 24 outputs the output signal processed by the active communication processing device 9 and the output signal processed by the test target communication processing device 8 from the storage medium 31 and the storage medium 32, respectively. Get and compare.
In step S208, it is determined whether the result of the comparison in step S207 is normal. For example, when a pseudo call similar to the active communication processing device 9 is input to the test communication processing device 8, the output signal of the active communication processing device 9 and the output signal of the test communication processing device 8 are the same. Is determined to be normal, and if different, it is determined to be abnormal. This determination result is notified to the software developer by displaying it on the operation terminal screen or writing it in a test result log file.
