Description

How to trace and monitor functional behavior in a communication system {Function Trace and Surveillance Mehtod in Communication System}

The present invention relates to a method for tracking and monitoring a functional operation of a communication system. In particular, the functional operation of the system is classified in detail according to an operation criterion, a function criterion and a priority criterion to track and monitor the function operation of the system. It is about how to.

In general, the No.7 signaling system is a common signaling system standardized by the International Telecommunication Union-Telecommunication standardization sector (ITU-T) of the International Telecommunication Union. Signal transmission unit that transmits various control signals for providing connection and various communication services or operation management of the communication network, the signal transmission unit for sharing the transmission control, error correction, security measures of the signal network, etc. to increase the versatility; It consists of user part which is designed individually according to application area such as telephone exchange and data exchange.

In addition, the signal processing speed is improved by using a separate signal link for separating and transmitting only the corresponding control signal separately from the communication line for transmitting voice or data, and providing various signal contents for the calling party and the called party. Data can be processed into one signal unit, and the length of the corresponding signal unit can be set variable according to the data amount.

As shown in FIG. 1, the general structure of the No. 7 signal network includes a signaling point (SP) and a signaling link (SL).

In this configuration, the signaling point is to send, receive, or transmit a signaling message generated by a user, and includes a signaling end point (SEP) for transmitting or receiving a signaling message and a pair of signals. There is a Signaling Transfer Point (STP) that carries messages from one link to another. The SEP includes an operating point (OP) that generates a signaling message and a destination point (DP) that is a destination of the signaling message.

On the other hand, the signal link is a logical information transmission path connecting the corresponding signal points, and the set of such signal links is called a signaling link set (LS), and a path for delivering a message to the signal point is a signal route ( Called Signaling Route (SR), a set of signal routes defined for carrying traffic to one destination is called a Signaling Route Set (RS).

As described above, the No. 7 signal network is composed of a signal point, a signal link, a signal link set, and specification data such as a signal route, and a signal link set that directs a signal message generated by an origin point to a destination point. Call routing and service requests are performed by performing routing functions delivered over a specific signal link.

Assuming that all signal link sets in the No. 7 signal network are available, each signal point of the signal network has an internal protocol structure as shown in Fig. 2, and the No. 7 signal network has a data user part (Data User). ISDN user considering the correspondence between various DUP), telephone user part (TUP) in charge of processing of telephone signal and call exchange connection control, and various services of Integrated Services Digital Network (ISDN) An ISUP (ISDN User Part) and a Signaling Connection Control Part (SCCP) that enable the transmission of various signals and data other than the normal line-compatible control signals are provided in the MTP (Message Transfer Part) which is a message transfer part. Connected.

In FIG. 2, TC (Transaction Capabilities) performs a question and answer processing function to the SCCP user unit. Here, the signal point performing only the signal transfer function may not have a protocol such as SCCP and ISUP.

As described above, the MTP is a function unit that distributes signal transmission control, error correction, and security processing of a signal network in order to increase versatility, and reliably delivers No.7 signal related messages transmitted and received between signal points. As shown in Fig. 3, the signal message processor 1 performs signal traffic transmission and user part distribution functions, and all specifications (signal points, signal links, signal links) belonging to the signal network for reliable signal message transmission. And a signal network manager 5 which efficiently maintains the correspondence between the specifications and manages the signal network shape while efficiently using the sets and signal routes).

In this configuration, the signal message processing unit 1 includes a message discriminating unit 2, a message distributing unit 3, and a message routing unit 4, wherein the message discriminating unit 2 receives the received message. The message is analyzed by checking whether the final destination of the message is its own country, the message distribution unit 3 delivers the message to the user part of the local station, and the message routing unit 4 transmits the neighbor signal to transmit the message to the final destination. Route to the signal route associated with the point.

On the other hand, the signal network manager 5 includes a signal traffic manager 6, a signal link manager 7, and a signal route manager 8, but the signal traffic manager 6 is in an unavailable state. When the traffic signal is changed to the other link or route, or temporarily slows down, the signal link management unit 7 manages the restoration, activation or disabling of the link, and the signal route management unit 8 provides information on the signal route state. Reliably exchange between signal points in the signal network.

After analyzing, designing, and implementing the function in the communication system that has built No.7 signaling system, it is possible to check whether the function is operating normally and the cause of the failure during system operation. (FAST) Inserts a print statement into the source in addition to the part that the operator wants to monitor in the module unit of the system by using a terminal and a notebook. After generating and executing the execution code of the relevant print statement, it was output to the monitor for tracking and monitoring.

Since the method is 1200 to 1800 bytes per second at a speed of 9600bps or 14400bps, if 40 bytes are output in one print statement, 30 messages per second can be output, so the signal processing speed is slow.

In addition, fast terminals cannot be stored continuously, making it difficult to keep track of many data outputs.

Therefore, in the case of tracking and monitoring according to the above method, not only tracking and monitoring is easy, especially tracking and monitoring are impossible during system operation, and when a failure occurs during system operation, it is difficult to determine the cause of the failure, thereby paralyzing the service. There was a problem.

SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to subdivide a function operation state of a communication system according to an operation classification criterion, a function classification criterion and a priority criterion, and extract only the matters to be monitored for function of the system. By tracking and monitoring the operation, it is easy to monitor the operation according to the function development and to monitor the function operation during system operation.

In addition, another object of the present invention is to enable stable operation of the system by enabling the identification of failure causes that are difficult to track when a system failure occurs.

A feature of the present invention for solving the above object is a method for tracking and monitoring a function operation in a communication system, comprising: classifying a function operation of a communication system according to an operation criterion; Classifying a functional operation of the communication system according to a functional criterion; Classifying functional operations of the communication system according to priority criteria; Inputting tracking and monitoring data according to the classification; Tracking and monitoring a functional operation of the communication system based on the input tracking and monitoring data; And outputting or storing a result of tracking and monitoring a functional operation of the communication system.

In addition, in the case of classifying the functional operation of the communication system according to the operation classification criteria, the log file is classified according to the error, reception, transmission, internal operation, and the result of tracking and monitoring the functional operation of the communication system. Characterized in that stored in.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, the functional operation execution state of the communication system is divided and tracked and monitored according to the classification criteria. When the functional operation execution state of the communication system is classified based on the classification criteria, as shown in FIG. A classification process (step S11), a classification process according to the functional criteria (step S12) and a classification process according to the priority criteria (step S13) are performed.

The process of classifying according to the operation criterion (step S11) includes an error operation for outputting a data having a problem in the system or a data having a problem at the time of operating the system when receiving a signal input from the adjacent signal point, and inputting from the adjacent signal point. The functional operation of the system is performed according to a receiving operation for receiving a signal, a transmitting operation for receiving an input signal from the adjacent signal point and transmitting the signal to another adjacent signal point, and an internal operation for executing a procedure by calling a procedure inside the signal point. Track and monitor

The process of classifying according to the functional criterion (step S12) is to classify the function of the signal network management unit 20 of the signal network management unit in the message transmission unit of No. 7 signaling method as an example. Same as

5 shows a configuration according to the function of the message transfer unit, and the signal message processing unit 10 performing the signal traffic transfer and the user unit distribution function and efficiently use the specifications belonging to the signal network for reliable signal message transfer. While maintaining the correspondence between the specifications and the signal network management unit for performing a function of managing the shape of the network is configured.

In the message transfer unit function, the signal network manager 20 includes a signal traffic manager 23, a signal link manager 25, and a signal route manager 27.

The signal traffic manager 23 functions to switch signal traffic to one or more bypass links when the signal link becomes unavailable as a result of failure, disablement, closure, or prohibition. Avoid the loss, duplication, or misordering of messages in traffic, and perform recovery procedures for all messages not received at the other end before resuming traffic on the bypass link.

In addition, when the signal link becomes available as a result of the recovery, activation, closure recovery, or de-inhibition of the unusable signal link, it functions to reverse the traffic that was converted to the bypass link back to the useful normal link. At this time, an order control procedure for avoiding loss, duplication or wrong order of the message, and a time control switching procedure when the relative signal point cannot be connected at the signal point initiating the return switching function.

Among the functions of the signal traffic management unit 23, the signal traffic rerouting function is made available by forcibly rerouting related signal traffic to the bypass route or recovering the normal signal route that was unavailable when the signal route destined for a specific destination point becomes unavailable. When this is done, control rerouting from the detour route to the normal route to maintain optimal routing.

At this time, the signal link to which the signal route belongs may transmit signal traffic related to another called point, and control rerouting is performed only for traffic related to a specific called point.

The signal link management unit 25 is a function for maintaining and restoring the capacity of the set link set, and the function includes a function of signal link activation, signal link neutralization, signal link recovery, and signal link set activation. Perform procedures to maintain and restore capacity in the link set.

The signal route management unit 27 exchanges the unavailability and availability information of the signal route by the prohibition of propagation and the propagation allow procedure respectively, and the update of the signal route status information is performed by the signal route set test procedure function. The runaway state of is communicated by the transfer control procedure function.

The transmission prohibition procedure function is performed at a signal point operating as a signal transmission point for a corresponding signal route to inform one or more adjacent signal points of unavailability of a specific signal route, and a signal transmission point that cannot reach a specific destination point is Send a prohibition message to an adjacent signaling point, send a prohibition message to an adjacent signaling point belonging to that signaling route when resuming traffic to a signal route that has not been used so far, and send a message to an unreachable destination When a message is received, the transmission prohibition message is sent to the signal point that sent the message.

The forwarding procedure procedure function is performed at a signaling point acting as a signaling point for a route related to the called point when notifying one or more adjacent signaling points that it can start routing a message related to a specific called point. When the easy signal route is recovered and can deliver the signal traffic destined for a specific destination, a transmission permission message is sent to all adjacent signal points. When stopping traffic to a route that was used as a result of a reversion switch or control rerouting, a forwarding permission message is sent to an adjacent signaling point belonging to this route.

The test procedure function of the signal route set is used to test whether signal traffic from a signal point to a particular destination can be routed through adjacent signal transit points.

The transfer control procedure function is a procedure in which a signal transmission point that detects a congestion of a destination point is used to inform the congestion state of the originating signal point. On receipt of a message that requires delivery, a delivery control message is sent to the originating signaling point for the first and subsequent N messages.

In this manner, the signal traffic management 23 of the signal network management unit 20, the signal route management unit 27, and the signal link management unit 25 are classified according to the respective functions of monitoring and tracking.

The process of classifying according to the priority criteria (step S13) is to track the function operation of the system, stop functioning, important function operation and failure of the system (e.g. DBMS (Data Base Management System) data inconsistency, start the signal point restart or Terminating, activating or deactivating a signal linkset, or receiving a signal at an adjacent signal point, causing an error in the data, or loop processing (e.g., signal path available or unavailable due to available or unavailable signal linksets) Processes and tracks and monitors the operation of functions by giving priority to the procedures in the loop.

The operation of classifying, tracking and monitoring according to the classification criteria will be described with reference to FIG. 6 as follows.

First, a method of classifying according to the criteria (step S11, step S12, step S13) is selected (step S51), and then tracking and monitoring data are input according to the classification criteria (step S52), and the tracking and monitoring of the function operation are performed. The function operation is tracked by the data (step S53), and the program tracking and monitoring the function operation outputs a log message to the monitor based on the input data or stores the log message on the disk of the system (step S54). The log message outputted or stored is analyzed (step S55).

By analyzing the log messages stored in the output or log file, the function operation can be tracked and monitored.
