FIG. 5 is a flowchart illustrating resetting the upper processor when an upper processor is initialized. 6 is a flowchart of a function, and FIG. 6 illustrates a flowchart of a function of resetting when a lower processor is initialized in an embodiment of the present invention.

In the above flow chart, step 10 of FIG. 2 is a step of analyzing the tracking information of the ATM signaling message in the low speed and high speed controller 20, 40, which is an upper processor.

In step 20 of FIG. 2, the low-speed and high-speed device controllers 10 and 30, which receive the layer 3 message from the low-speed and high-speed controllers 20 and 40, the upper processor, store tracking information of the ATM signaling message. Is a step

In step 30 of FIG. 2, the low speed and high speed device controllers 10 and 30, which are lower processors, report tracking report information of the Layer 2 message to the low speed and high speed controllers 20 and 40, which are upper processors.

Step 40 of FIG. 2 is a step of reporting trace report information of the Layer3 message from the low speed and high speed device control unit 10 and 30 which is a low processor to the low speed and high speed control unit 20 and 40 which is a high processor.

Step 50 of FIG. 2 illustrates a step of outputting the tracking information to the operator's CRT by the upper and lower speed controllers 20 and 40, which are upper processors.

Looking at this in more detail with reference to Figures 3 and 4,

In step S100 of FIG. 3, the operator inputs input parameter information for tracking the ATM signaling message, which is an operator command, through the operation server 50 to the high speed controller 40, which is the upper processor of FIG. 1.

In this case, the input parameter information is a parameter of STATUS including ALLOW to allow the tracking function of ATM signaling messages and INHIBIT to disable the tracking of ATM signaling messages;

UNIT which tracks all messages sent and received by the low and high speed device controllers 10 and 30 corresponding to the lower processor by device controller, tracks all messages sent and received on the link, and tracks all messages sent and received by the corresponding VPI. parameter,

Message parameters include an ALL that tracks all messages as messages and displays them on the operator screen, and an IND that allows you to selectively register multiple messages that can be individually registered and tracked on the operator screen. ,

A parameter of the level including a normal range for outputting only the command information and a detailed yield range for outputting the option information, and

After all the messages were analyzed and processed, the output parameters including FULL, which outputs to the operator's screen, and RAW, which outputs all messages to the operator's screen as hexadecimal values, were included.

Here, the high speed control unit 40 and the low speed control unit 20, which are the upper processors, are connected by a LAN cable as shown in FIG. 1, and the tracking of the ATM signaling message as an operator's command through the operation server 50 is performed. When the parameter information is input, the connection state of the low speed device controller 10 and the high speed device controller 30, which are lower processors, as shown in step S101 of FIG. Done.

Accordingly, the high speed controller 40 may check an error in parameter information of an ATM signaling message input through an operator command in step S102 of FIG. 3.

That is, when the new message of the ATM signaling system is newly registered or changed, the high speed controller 40 searches for and compares the message information of the existing ATM signaling system, and checks the parameter error of the input value from the comparison result. If the input value is wrong or is consistent with the previously stored value, the result of message analysis of the newly registered and changed ATM signaling is searched without storing the message of the newly registered or changed ATM signaling.

For example, the high speed controller 40 registers and changes the tracking function of the ATM signaling message so that an operator can easily analyze and take action by detecting a matching status error and data transmission on the interface and a status and a cause of the error. This is described in detail.

The operator registers a message tracking function of ATM signaling method through the operation server 50 for the resource to be analyzed or the error occurs, and the operator registers the ATATUS command of the operator through the operation server 50 for registration. Set the parameter information to ALLOW.

Next, the operator selects and inputs the parameter information of the UNIT to be tracked by the low speed and high speed device control unit 10 or 30, tracked by the corresponding link, or tracked by VPI, and recommended by the ITU-T or ATM FORUM. Enter the message parameter information to complete the message, or optionally enter only the message you want to trace.

Next, the operator inputs parameter information for selecting and specifying the normal range for outputting only the command information or the detailed item range for outputting the option information as the execution range for the message tracking in ATM signaling method through the operation server 50.

Next, the operator selects whether to use the FULL function for processing and outputting the message, which is easily tracked by the output method of the message through the operation server 50, and the RAW function for outputting the hexadecimal number as it is. Enter.

Then, when the parameter information selected and designated as described above is input to the high speed controller 40 which is the upper processor through the operation server 50, the high speed controller 40 receives the error and checks the error of the input parameter information. If there is, or the registration or change is wrong, the information is output to the operator screen along with the FAIL REASON.

On the other hand, if there is no error in the information of the input parameter, the high speed controller 40 is to send down the setting information of the parameter information to the high speed device controller 30 which is a lower processor in step S103 of FIG.

The high speed device controller 30 updates the information received from the high speed controller 40 as in steps S104 and S105 of FIG. 3 and transmits the update information to the high speed controller 40 which is a higher processor.

Then, the high speed controller 40 stores the setting registration information of the input parameters in the database as shown in step S106 of FIG. 3 and outputs the input message as well as the registration status to the operator screen.

Next, when the registration information of the ATM signaling message tracking as described above is to be changed, the high speed controller 40 compares the tracking information to be changed with the previously registered tracking information.

At this time, if the tracking information to be changed is matched or abnormal with the previously registered tracking information, the high speed control unit 40 outputs the matching or abnormal tracking information to the operator screen with the FAIL REASON, and in the normal case the lower processor The tracking information of the high speed device controller 30 is changed.

Here, when the change of the tracking information is normally made, the high speed device controller 30 stores the changed message tracking information of the ATM signal type in the database of the high speed controller 40, and the previous tracking information and the changed tracking information. To be displayed on the operator's screen.

On the other hand, in the state where registration and modification of the ATM signaling message tracking function are made as described above, the tracking of the ATM signaling message proceeds in the following procedure.

That is, when the low-speed and high-speed device control unit 10 (30) that processes the Layer 2 frame and Layer 3 messages in step S201, S202 of FIG. 4 sends and receives an ATM signal type message, the high-speed control unit 40 If stored in the database, that is, if the message corresponding to the registered message by filtering the registered message in the messages sent and received from the device control unit, link, VPI, the low speed and high speed device control unit (10) (30) step S203 In the low speed and high speed control unit 20, 40 transmits the tracking information of the ATM signaling message.

At this time, when the low-speed and high-speed control unit 20, 40 is in the INH state by the parameter information input by the operator, when the above message is not reported, but is ALLOW by the parameter information input by the operator In step S204 of FIG. 4, the above message is reported to the upper processor low speed and high speed controller 20 and 40. FIG.

Then, the low speed and high speed control unit 20, 40 receives this to determine the output method of the message based on the information requested by the operator.

That is, the high speed controller 40 selects an output range for the message of the ATM signaling method and an output method thereof based on the input parameter information whose error is checked in step S205 of FIG. 4.

At this time, assuming that the output range of the selection result message is divided into a normal range and a detailed yield range, in the normal range, the high speed controller 40 outputs only an ATM signal type message corresponding to the command information. In the case of a detailed yield range, the high speed controller 40 outputs an ATM signal message including option information.

Next, when the output method of the selection result message is FULL, the high speed control unit 40 processes the message so that an operator can easily analyze the message, and in the case of RAW, the high speed control unit 40 displays the message. It will be printed in hexadecimal without processing.

At this time, when the above message output is normally performed, the header information of the message is configured to mount the registration information of the ATM signaling system message, and the body part is loaded with the processed information.

Here, in the case where the information from the high speed device controller 30, which is a lower processor, is abnormal, a popup message is popped up on the operator screen so that the operator can easily recognize the information.

On the other hand, when the low-speed and high-speed control unit 20, 40, which is the upper processor, as shown in Figure 5 is initialized, to notify the operator screen of the initialization state so that the restoration function for the message tracking of the ATM signaling system can proceed immediately.

Since the tracking information of the ATM signaling messages between the device controllers 10 and 30 may be inconsistent, the low speed and high speed controllers 20 and 40 may perform the steps of FIG. 5 on the operator's screen through the operation server 50. The upper initialization information is reported as in S302.

Next, the low speed and high speed control unit 20, 40 reads the tracking information of the ATM signaling message stored in the database, and then the low speed and high speed device control unit 10 (30), which is a lower processor, as shown in step S303 of FIG. To send).

At this time, the low processor and the low speed and high speed device control unit 10, 30 receives the tracking information of the ATM signaling message transmitted from the low speed and high speed control unit 20, 40, which is a high processor and then the step of FIG. By comparing the tracking information with the previous tracking information as in S304,305, and transmitting the matched tracking information to the low speed and high speed control unit 20 (40), which is the above processor, The low speed and high speed control unit 20, 40 is to be reset.

In addition, when the low speed and high speed device controllers 10 and 30, which are lower processors, are initialized as shown in FIG. 6, the low-speed and high speed controllers 20 and 40, which are upper processors, are notified of the initialization state. The restore function for the message tracking of the user can be performed immediately.

That is, when initialization of the low speed and high speed device controllers 10 and 30 which are the lower processors is performed as in step S311 of FIG. 6, the initialization state is the low speed and high speed controller that is the higher processor as in step S312 of FIG. 6. 20) (40).

Then, the low speed and high speed control unit 20, 40 reads the tracking information of the ATM signaling message stored in the database, and then, as shown in step S313 of FIG. To send.

At this time, the low speed and high speed device controllers 10 and 30, which are the lower processors, receive the tracking information of the ATM signaling message transmitted from the low speed and high speed controllers 20 and 40, which are the upper processors, and then perform this step. Compare the tracking information with the previous tracking information as in S314,315, and transmit the matched tracking information to the low speed and high speed control unit 20, 40, which is the upper processor, The low speed and high speed device control unit 10, 30 will be able to reset.
