DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a PSTN (Public
Switched Telephone Network) and IP (Internet Protoco
l) Used for a line quality test of a VoIP (Voice over IP) network composed of a network. The line quality test includes a transmission quality test and a connection quality test.

[0002]

2. Description of the Related Art FIG. 21 shows an overall configuration of a VoIP network.
As shown in FIG. 21, the conventional VoIP network test shows that the PS
Since the communication systems of the TN and the IP network are different, it is difficult to perform a line test from End to End. That is, since the PSTN and the IP network that constitute the VoIP network are individually tested, there is a problem in the accuracy of the test. Also, since it is necessary to start a test from a plurality of operation support systems (hereinafter abbreviated as OSS), each OSS
A test command must be issued from the terminal.

A conventional test execution procedure will be specifically described with reference to FIGS. 22, 23, 24, and 25. The subscriber exchange ladder accommodating the telephone subscriber shown in FIG.
(Abbreviated as GC) and a transit exchange ladder (hereinafter abbreviated as IC) for connecting the local exchanges (section A).
In the transmission quality test, a path test between the GC and the IC is performed by using the test function of the OSS of the PSTN. In the connection quality test, the OSS test function of the PSTN is activated and the call is received from the GC to the test trunk of the IC to confirm the normality.

[0004] IC to media gateway shown in Fig. 23 (a device for communicating between different communication systems from an existing public telephone network to an IP network (or vice versa).
), The transmission quality test is P
Using the OSS test function of each of STN and MG, I
A pass test between C and MG is performed. Connection quality test is PS
TN, call agent (a device that connects to a common channel signaling network (SS7) and controls a communication path; hereinafter abbreviated as CA) IC to MG using the test function of each OSS
To the test trunk and confirm its normality.

[0005] In the test between the adjacent routers L1 of MG to MG ([section C]) shown in FIG.
G, ping using the test function of the IP network management system
(ICMP (Internet) included in the IP layer of TCP / IP
(Utility command) to check whether the packet has reached the destination using Control Message Protocol). The connection quality test uses the test function of the OSS of the CA to make a call from the MG to the test telephone P1 provided in the adjacent router L1, and confirms the normality of the routing table.

[0006] In the IP network not including the MG shown in FIG. 25 ([section D]), the transmission quality test performs ping using the test function of the IP network management system. The connection quality test uses the test function of the IP network management system to send and receive a call within the IP network to check the normality of the routing table of the router.

[0007]

As described above, the conventional Vo
In the test of the IP network, since the communication method of the PSTN and the IP network are different, a plurality of OSSs must be used autonomously in a decentralized manner. Difficult to test.

As a result, the PST constituting the VoIP network
There is a possibility that the test accuracy when independently testing the N and the IP network may be reduced, and it is difficult to isolate a failure in the VoIP network.

The present invention has been made in such a background. Even in a test environment in which a test section is divided, an accuracy close to the end-to-end line test can be obtained, and the quality deterioration section can be separated. It is an object of the present invention to provide a line test method and apparatus, a program, and a recording medium capable of efficiently determining the cause of quality deterioration.

The test in this section is a section, and the test N. G. FIG. From the integrated OSS to CA, MG, IP network management OSS
The test function of each OSS is activated and used.

In the present invention, as shown in FIG. 14, in the transmission quality test, the OSTN test function of each of the PSTN and MG is activated to perform a path test between GC, IC, and MG. The connection quality test activates the OSS test function of each of the PSTN and the CA and causes the GC to terminate the test on the MG test trunk.
Check the translator's normality by using the loopback function. Thus, it is possible to prevent a decrease in test accuracy near the connection point between the PSTN and the MG.

As shown in FIG. 15, a test telephone P1 is installed in the adjacent router L1 between the IC and the MG adjacent router L1. Transmission quality test is PSTN, M
Activate the test function of each OSS of G and perform GC ~ IC ~
A path test between the MGs is performed, a test function of the IP network management OSS is activated, and a ping is performed between the MG and the adjacent router L1. Connection quality test is PSTN, CA, IP network management OSS
The test function is activated and the call is received from the IC to the test telephone P1 installed in the router, and the normality is confirmed. This gives PS
It is possible to prevent a decrease in test accuracy near the connection point between the TN and the IP network.

As shown in FIG. 16, in the MG to IP network, the transmission quality test activates the test function of the IP network management system and performs ping. In the connection quality test, the test function of the CA's OSS is activated, and a call is made from the MG to the subscriber accommodated in the IP network to confirm the normality of the CA setting information. Thereby, the test accuracy in the IP network including the MG can be improved.

As shown in FIG. 17, PSTN (G
C to IC), the transmission quality test is performed by PSTN O
The test function of the SS is activated to execute a path test between the GC and the IC. In the connection quality test, the OSS test function of the PSTN is activated and the call is received from the GC to the test trunk of the IC to confirm the normality.

As shown in FIG. 18, in the IP network not including the MG, the transmission quality test is performed by the IP network management OS.
The test function of S is activated and ping is performed. In the connection quality test, the test function of the IP network management OSS is activated to send and receive a call in the IP network, thereby confirming the normality of the routing table.

Also, as shown in FIG.
In, the transmission quality test activates the OSS test function of each of the PSTN and the MG, and performs a path test between the IC and the MG. In the connection quality test, the OSS test function of each of the PSTN and the CA is activated, and the call is transmitted to the test trunks of the IC to MG to confirm the normality.

Also, as shown in FIG.
In, the transmission quality test activates the test function of the MG and IP network management system and performs ping. In the connection quality test, the test function of the OSS of the CA is activated to receive a call from the MG to the test telephone P2 connected to the router L2 and confirm the normality of the routing table.

Thus, for example, when performing a line test in a VoIP service composed of a PSTN and an IP network, a test can be performed from the integrated OSS, and a unified test can be performed and a highly accurate test can be performed. .

[0051]

As described above, according to the present invention,
Even in a situation where the communication schemes of the PSTN and the IP network are different in the VoIP network, by performing a test from the OSS integrating a plurality of OSSs, End to E over the entire section
nd line quality and routing setting normality can be tested. As a result, an accuracy close to that of the end-to-end line test is obtained, so that it is possible to divide the quality deterioration section and to investigate the cause of the quality deterioration.
