In addition, the operation center 10 stores equipment information provided in telephone stations scattered throughout the country, and the operation center 10 may collect status information on specific equipment of a specific telephone station by using the equipment information. .

Particularly, in the present invention, the operation center 10 includes an operator GUI 11 constituting a screen for inputting a command according to a regular test in addition to an internet matching unit for access to the Internet, and information of each network management equipment (IP). Address, equipment type, manufacturer, name information, etc.), test result values, and various statistical result values according to the test conditions input through the operator GUI (11) in conjunction with the DB (13), DB (13) A test execution unit 12 is provided for transmitting a test command to the network management equipment and performing a statistical function for a specific item.

Hereinafter, a method for managing network equipment in a high speed internet access service according to an embodiment of the present invention will be described in detail with reference to the flowcharts shown in FIGS. 2 to 4.

When the regular test mode is set through the operator GUI 11 of the operation center 10 (S2), the test performing unit 12 receives the conditions for the regular test from the operator GUI 11 (S4), Periodic test conditions are stored in the DB (13) (S4, S6). At this time, the condition for the regular test input from the operator GUI 11 is the name of the telephone station to be tested, the first station number, the last station number, the equipment type, the registration date, the test cycle, the test time, and the like.

Subsequently, the test execution unit 12 monitors the test cycle of the periodic test conditions, and when the current time reaches the test cycle (S8), the periodic test conditions, that is, the telephone station name, the first station number, the last station number, and the equipment type. Search the network management equipment corresponding to the DB from the DB (13) to send a PING test request message to each network management equipment to perform the PING test (S10), and when a PING test response message is received from the network management equipment, the PING test is performed. After determining that it is successful (Yes in S12), the socket communication is requested to each network management device, and then the HELLO test request message is transmitted to the network management device in response to the socket communication request (S16).

On the other hand, unlike the case described above, if the PING test response message is not received from the network management equipment despite the transmission of the PING test request message to each network management equipment in step S10, it is determined that the PING test failed (No in S12). Notify the operator GUI 11 of the periodic test failure (S14).

As a result of performing the HELLO test in step S16, when the HELLO test response message is received from the network management equipment, it is determined that the HELLO test is successful (YES in S18). The results of the PING test and the HELLO test for the network management equipment are determined by using DB ( 13), the test result of the network equipment can be used as statistical data when the statistical analysis request from the operator GUI (11). The DB 13 also stores test result values for equipment for which the PING test or HELLO test failed, and the test results for the network devices that failed the PING test and the HELLO test in the test when a statistical analysis request is made from the operator GUI 11. Make it available as a statistical value.

FIG. 3 is a flowchart for explaining in detail the PING test procedure described in step S10 of FIG. 2, and FIG. 4 is a flowchart for explaining in detail the HELLO test procedure described in step S16 of FIG. 3.

According to the flowchart shown in Fig. 3, the PING test is a network in which the test execution unit 12 corresponds to the periodic test conditions (telephone station name, first station number, end station number, equipment type, etc.) from the equipment information stored in the DB 12. Search for the management equipment (S30), and search the IP address for the network management equipment found in step S30 from the DB (12) (S32).

Subsequently, the test execution unit 12 sequentially transmits the PING test request message to the IP addresses of the searched network management equipments, and determines whether the PING request message is transmitted to all the network management equipments searched at step S32 (S36). If the PING request message has not been transmitted for all the network management equipments found in step S32, step S34 is performed to transmit the PING request message for all the equipments found in step S32.

In step S34, since the PING test request message from the test execution unit 12 is transmitted to the network management equipment only when the network management equipment is physically normally connected, an operation center provided with the test execution unit 12 ( 10) PING test response message is transmitted to the operation center 10 only in the network management equipment in the physically connected state. When the PING test response message is transmitted to the operation center 10, the test execution unit 12 of the operation center 10 is determined to be a successful PING test in step S12 of FIG.

As can be seen from the description above, the test performing section 12 performs a PING test on the equipment, so that it is possible to know whether each equipment is normally connected to the Internet. This PING test is a technology used to check the Internet connection between devices for a device built on a network using TCP / IP.

Next, the HELLO test procedure described in step S16 of FIG. 2 will be described in detail with reference to FIG. 4.

In the HELLO test, the test execution unit 12 searches for network management equipment corresponding to the regular test conditions (telephone station name, first station number, end station number, equipment type, etc.) from the device information stored in the DB 12 (S40), and the DB. From 12, search for IP addresses for network management devices found in step S30 (S42).

Subsequently, the test execution unit 12 sequentially requests socket communication to the searched IP addresses of the network management equipment (S44). The socket may be referred to as a communication connection point written in software, and an application of a network may transmit / receive data to a communication network through the socket. In other words, the socket serves as a gateway to the TCP / IP layer in the application, and the interface between the application and the socket is called a socket interface.

Therefore, the socket must be open for communication between devices. If the device that has received the socket communication request in step S44 has the socket open and the socket communication is possible, the socket connection success message is transmitted to the test execution unit 12.

When the socket connection report message is transmitted from the network management equipment, the test execution unit 12 determines that the response to the socket communication is successful (S46), and transmits a HELLO test request message for the corresponding equipment (S50).

In this case, the data format of the HELLO test request message transmitted to the device is shown in Figure 5, common sub-information frame for storing the header information (a), EMS IP address frame (b), system ID frame (c) , A device name frame (d), and a separator frame (e).

Describe the function and size of each frame.

The header information stored in the common part information frame (a) includes a service identifier for facility classification (3 bytes), an interworking system identifier for distinguishing a test request system (1 byte), and a message identifier for identifying whether a test request or a response ( 1 byte), the correlation ID (2 bytes) that is the unique value of the requested message, the messagebody length information (2 bytes) corresponding to the number of digits of the frame excluding the common part information, and the message type indicating the test type. Information (1 byte) is provided.

The EMS IP address frame (b) stores the IP address of the device to be tested for HELLO and has a size of 15 bytes.

The system ID frame (c) stores the ID of the manufacturer of the equipment, and has a size of 5 bytes. 2 bytes of 5 bytes store a code value for identifying a device provider, and 3 bytes indicate a device type. The code value to distinguish is stored.

The device name frame (d) stores a code value corresponding to the name of the device and has a size of 10 bytes.

In the delimiter frame (e), a delimiter according to the standard code of the equipment is stored, and the size is 3 bytes.

Subsequently to step S50, it is determined whether the HELLO request message is transmitted for all the network management devices found in step S40 (S52). If the HELLO request message is not transmitted for all the network management devices found in step S40, step S44 is performed. The socket communication is requested for all the devices found in step S40, and the HELLO request message is transmitted.

When the network management equipment, which has received the HELLO test request message from the test execution unit 12 by the step S50, checks the connection status with the network equipment (DSLAM, NAS, HDT, etc.), if the network equipment is normally connected, When the HELLO test response message is transmitted to the operation center 10 and the network management equipment transmits the HELLO test response message to the operation center 10, it is determined that the HELLO test is successful in step S18 of FIG. 2.

On the other hand, if a socket connection success message is not transmitted from the network management equipment (No in S46), the test execution unit 12 notifies the operator GUI 11 of the HELLO test failure (S48), and proceeds to step S52 described above. .

Through the HELLO test described above in FIG. 4, the network management equipment maintains a normal connection with the network equipment to which the network management equipment normally operates. When the line test command is transmitted from the operation center 10, can the track test be normally performed? It is checked.

Although not described in FIG. 2, the operator GUI 11 may extract statistical data for each item using the PING test result value and the HELLO test result value stored in the DB 13.

For example, if a statistical analysis is requested for each telephone station, system ID, or test time, the test execution unit 12 determines the telephone station, system ID, EMS IP, PING test result value, and HELLO test result value for the test success result. , Test time, etc. may be displayed, and telephone station, system ID, EMS IP, PING test result, HELLO test result, and test time may be displayed for the test failure result.

On the other hand, the present invention has been described that the PING test and HELLO test is performed at regular intervals with the operator set the regular test mode, but the PING test and HELLO test is performed in real time when the operator requests to perform the PING test or HELLO test It can also be configured to

According to the present invention as described above, by managing the status of the equipment by collecting the status information of the equipment providing the Internet access service periodically or in real time regardless of whether the failure of the subscriber, it is possible to quickly detect the failure of the equipment The equipment can be repaired and restored to normal. Therefore, it is possible to recover the failure equipment before the subscriber reports the failure, thereby providing a high quality internet access service for the subscriber.

On the other hand, the present invention is not limited to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, such modifications and changes should be regarded as belonging to the following claims. will be.
