The present invention relates to a method of analyzing a V5.2 protocol message used in a communication system, and more particularly, to a protocol message transmitted and received between an exchange system and an access network (hereinafter referred to as "AN"). It is about how to analyze.

The current exchange system is designed to accommodate a variety of ANs with the V5.2 protocol. In the case of accommodating such various ANs in the exchange system, if a problem occurs in matching, the correct method for analyzing the cause is to use a V5.2 protocol analyzer to trace the cause. The protocol analyzer can analyze messages for each entity of the V5.2 protocol.

The V5.2 protocol analysis equipment as described above has the usefulness and convenience in many aspects, including the function of outputting each V5.2 protocol message as a hexa (hex) value and the function of outputting it through analysis. Due to the expensive aspect of the expensive hardware equipment, each exchange country was not able to operate the equipment. Therefore, when the actual exchange does not have the V5.2 protocol analysis equipment, if there is a problem in operation, the exchange operator could not track the cause of the problem efficiently.

 Accordingly, an object of the present invention is to analyze the contents of a V5.2 protocol message by tracing by user port or protocol entity (hereinafter referred to as "PE") in an exchange system, and the result The present invention provides a method and apparatus for analyzing a V5.2 protocol message in an exchange system that outputs a.

Another object of the present invention is a built-in tool for tracking and analyzing the messages of the V5.2 protocol inside the exchange system, and analyzes the V5.2 protocol messages transmitted and received between the exchange system and AN by the error A method and an apparatus for outputting a message are provided.

In order to achieve the above object, the present invention provides a user port in an exchange system having a protocol matching processor capable of connecting various ANs and a man machine interface (MMI) for interfacing between an operation and maintenance termial. Or in response to an input of a trace registration request message for each PE in AN units, registering with the protocol matching processor, and identifying all registered targets (user ports or ANs) when one or more pieces of information exist. The registration information checking process outputs the tracking information for each PE to the terminal, and when the V5.2 protocol message for the registered target is received, the message is classified by PE and the normality of the protocol message is searched for the result. Characterized in that it comprises a message analysis process provided to the terminal.

Hereinafter, a method of transmitting a message to a network management center according to an exemplary embodiment of the present invention will be described with the accompanying drawings. In the following description, the detailed items for such configurations are described in detail in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without these specific details.

1 is a block diagram of an exchange system having a V5.2 protocol analyzer according to an embodiment of the present invention. In FIG. 1, reference numeral 10 denotes a switch, which is a Version 5.2 protocol peripheral processor (VSPP) 12 capable of connecting various ANs 18, and an MMI 14 for interfacing between external operating terminals. And a message located between the VSPP 12 and the MMI 14 and inputting a message trace registration from the MMI 14, a release of a trace function, a confirmation command of trace registration information, and the like, to be transmitted to the VSPP 12. And an analyzer 16 for analyzing the V5.2 protocol message output from the VSPP 12 and providing the result to the MMI 14.

In the apparatus of the present invention configured as shown in FIG. 1, when the exchange operator registers a message tracking function to the analyzer 16 through the MMI 14 in a user port or AN unit for each protocol entity (PE), the analyzer 16 ) Registers it as VSPP 12. When the V5.2 protocol message is provided from the VSPP 12, the analyzer 16 analyzes the registered protocol message and outputs the information to the MMI 14 in the form of a hexadecimal value or a message analysis according to the requirements. . At this time, all the V5.2 protocol messages include time information. Accordingly, the analyzer 16 of the switching system 10 as shown in FIG. 1 analyzes the V5.2 protocol message provided from the AN 18 by the command information input from the MMI 14 and provides it to the terminal. This operation will be more clearly understood by the contents described with reference to the drawings to be described later.

Figure 2 is a V5.2 protocol analysis flow chart according to an embodiment of the present invention, which is a view for explaining the control of tracking registration of the message, Figure 3 is a V5.2 protocol analysis flow chart according to an embodiment of the present invention This is a diagram for explaining controlling the untracking of a message. And, Figure 4 is a V5.2 protocol analysis flow chart according to an embodiment of the present invention, which is a view for explaining the confirmation of the tracking registration information of the message, Figure 5 is a V5.2 protocol according to an embodiment of the present invention As an analysis flow diagram, this is a diagram for explaining analyzing and outputting a received protocol message. Finally, Figure 6 is an exemplary diagram of tracking information data display in accordance with an embodiment of the present invention.

The program for the control flow as shown in FIG. 2 to FIG. 5 shows the analyzer 16 shown in FIG. 1, which may be implemented with a microprocessor and a memory.

Hereinafter, the operation according to the present invention will be described in detail with reference to the above-described configuration and drawings.

Now, when an operator inputs a trace registration request message using a terminal (not shown), the information is input to the analyzer 16 through the MMI 14. At this time, the analyzer 16 receives this information in step 22 of FIG. 2, and checks the request content in step 24. If the check result is normal, the analyzer 16 stores the contents of the tracking registration information in the internal memory area in step 26 and transmits the related contents to the VSPP 12 in step 28. For example, the tracking registration information for each PE is transmitted. Subsequently, when a message indicating that the registration is normally registered from the VSPP 12 is received in step 30 of FIG. 2, the analyzer 16 transmits a message indicating that the tracking registration is normally registered to the terminal through the MMI 14 to transmit a registration result. Print it out in the process.

At this time, the registration of the tracking information functions for each PE by user port or AN unit, and can simultaneously register a plurality of PEs and designate an output type. There are about 5 PEs. Among the 5 PEs, PSTN-PE, BCC-PE, CTRL-PE can be tracked by user port unit, and CTRL-PE, LCTRL-PE, PROT-PE can be tracked by AN unit. It is possible. The registration of the tracking function registered in the analyzer 16 and the VSPP 12 by the function as shown in FIG. 1 can be released by the control as shown in FIG. 2, which is as follows.

When the trace release request message is received from the operator through the aforementioned path in step 34 of FIG. 3, the analyzer 16 checks the request content in step 36 to determine whether it is normal or abnormal. In the case where the search result of step 36 is normal, the analyzer 16 deletes the content already stored in the internal area in step 38. In addition, the analyzer 16 transmits the related contents to the VSPP 12 in step 40 and requests the release of the tracking function. When receiving a message indicating that the message is normally released from the VSPP 12, the analyzer 16 transmits the release result to the terminal through the MMI 14 to display the release state. At this time, the release function may be released for a specific PE or all registered PEs by user port or AN unit as described above.

Confirmation of the tracking registration information is performed by the control process as shown in FIG.

If an acknowledgment message is received from the operator 46 confirming all the targets (user port or AN) for which the tracking function is registered through the above-described path, the analyzer 16 searches for information of the internal storage area in step 48. It is determined whether the target is registered. If the determination result of step 48 is normally registered, the analyzer 16 outputs a result of tracking or the like for each PE to the MMI 14 in step 50. If not registered, an error message, for example, a message indicating that the PE is not registered with the tracking function is transmitted to the MMI 14.

When the tracking registration of FIG. 2, the tracking function release of FIG. 3, and the confirmation of the tracking registration information of FIG. 4 are completed, the analyzer 16 receives the V5.2 protocol message transmitted from the VSPP 12 to assist the protocol message. It analyzes by the control like 5 and informs the MMI 14, as follows.

As mentioned above, the V5.2 protocol consists of five PEs. Among them, CTRL-PE is recognized as a common control protocol entity (CCTRL-PE) if it is registered at the same time as AN, and a port in DN (subscriber number) if entered at the same time as a user port. The message is recognized as a port control-protocol entity (PCTRL-PE).

When each message transmitted from the VSPP 12 in charge of the AN and V5.2 protocol interfaces is received in step 60 of FIG. 5, the analyzer 16 shown in FIG. 1 receives the protocol message input in step 62 for each PE. The message is analyzed through the analysis tool (analysis tool), which is already configured, and the protocol message is searched in step 64 of FIG. 5 to determine whether the protocol message is normal or abnormal. If the protocol message analyzed as a result of the search is normal, the analyzer 16 searches for the required output type (real time output / packet unit output) in step 66 of FIG. In the case of outputting in the real time tracking state, the analysis message is output to the MMI 14 in step 70, and in the case of outputting in packet units, the process in step 70 is performed when packet unit collection is completed in step 68. If it is determined that the analysis result of the protocol message is abnormal in step 64, for example, when the analysis of the input protocol message is impossible or the corresponding message, the analyzer 16 performs the MMI 14 without processing in the form of a hexa value. Outputs as is through.

The result of the message tracking by the above operation is always included in the time information is used to determine whether or not due to a response time error with the state AN when a problem occurs. The real-time output is to analyze the received message in real time and immediately output it through the MMI 14, and the packet unit output is to store and analyze the message in a certain unit (number). (14) This does not affect performance. That is, this function is provided for the purpose of not loading the MMI 14.

Therefore, the present invention described above can be used to 1) trace the mesh per protocol entity (PE), 2) enable or disable tracing for multiple PEs simultaneously, and 3) provide time information in the message trace result. This makes it possible to easily detect errors caused by response time errors. In addition, 4) the message output form is provided in the form of output in hexa value and in the form of analysis and output so that the result can be quickly known when monitoring with the terminal. 5) Tracking of Messages

In addition, the analyzer 16 according to the present invention has a software extensibility that can provide a related function through an up-grade of the software, thereby increasing economics and utilization.

As described above, the present invention can facilitate the call processing service of the AN subscriber that transmits and receives the V5.2 protocol message by embedding the V5.2 protocol analyzer in the exchange. By providing MMI immediately with which messages are problematic in the protocol entity, most problems can be solved without the need for a separate V5.2 protocol analyzer.
