The present invention relates to a routing specification management method of a signal network management system.

Signal relay consisting of STP (Signaaling Transfer Pont), which is the configuration information of common line signaling network (CCS No. 7), and SEP Signaling End Points that make / receive signal messages The routing specification table required to perform the functions of the Message Transfer Part (MTP) and the Signaling Connection Control Part (SCCP) of the Signaling Transfer Part (STP) suggests a signal path for signal message transfer, and therefore must be maintained and managed correctly. do.

These critical routing specifications are maintained in a fragmented system, which requires high performance and high stability, and, if managed, can lead to more confusion in maintaining a consistent signal path table in case of failure of the signal network. Therefore, a centralized and signaling network operation system (SIGNOS) is required to maintain and manage the routing specifications of the signaling network consistently.

Signaling exchange exchange (SMX-1) developed in Korea is CCITT Recommendation Q.700-Q716, Bule Book, Specification of Signaling System No.7, Specification and Recommendations Q.791 and Q.795, Bule Book, Signaling System No. Monitoring. Operations and Maintenance, developed according to recommendations. Therefore, the signaling network management system concentrates on the signal relay exchanges that make up the signaling network, collects measurement data on the usage, availability, and performance of the signaling network, and uses the collected data to monitor network traffic, traffic and performance. This is the first domestic management system that analyzes data and changes and verifies signaling network routing information. The similar system is SEAS developed in Bellcore of the United States, but it is not valid for domestic standards. There is this.

Accordingly, the present invention has been made to solve all the problems of the prior art, the signal between the signaling network management system (SIGNOS) and the signal relay exchange (SMX-1: Signaling Message exchange No. 1, hereinafter referred to as STP) Routing specification management of signal network management system that centralizes and maintains network routing information information, performs efficient management, effectively supports configuration change of signal network and communication network planning, and supports the stability of operation of signaling relay switch. Its purpose is to provide a method.

In order to achieve the above object, the present invention provides a printer, a user connection unit, a signal routing routing data process (RDMDAT), a signal routing routing search / replication process (SMSVF), and an STP routing data immediate / reservation change request and processing process ( REQCHG), STP routing data reservation command control processing process (DLYCHG), signal network configuration and history management database (NCFGDB, RCNVDB) and OMS routing data change, automatic output status information message and reservation processing response message reception processing process (RPTCOL) And SIGNOS / STP protocol processing network connection and SIGNOS / STP connection processing and signaling relay switch operation management subsystem (OMS) and signaling relay switch MTP (Message Transfer Part) and SCCP (signaling connection control part) performance management subsystem (SNM) General purpose computer used as a signal network management system with a built-in signal) and signal network monitoring according to the status and status of the signal network monitoring and routing specification In the routing specification management method of a signal network management system having a graphic output screen and a dummy operation seat performing a specification management task seat, the method for checking the signal network specification according to an input of an operator of the signaling network routing specification management seat. Stage 1 ; After performing the first step, if the network specification is confirmed, check the remote STP specification menu, and if it is confirmed, the STP execution response is received and processed by the routing data search command. A second step of outputting and ending the reception and processing result; After performing the first step, if it is confirmed that the signal specification is not confirmed, it checks the effect of the signal routing error, and if it is not a failure, orders change of processing immediately. Performing a process of initializing data according to a signal network plan and checking whether there is a signal network routing failure if not confirmed; After performing the third step, if the STP initialization is complete, copy and store it from the STP if it is completed, and if it is in progress, create SIGNOS initialization data and instruct SIGNOS to send the initialization data to the STP, and then transmit an STP execution response and process result. The fourth step; Characterized in that comprises a.

In the present invention, a signal network component and a management target unit of a signal relay switch and a signal network management system can be defined by a logical expression method, and a relational table is constructed, and the change of mutual data maintains an interface message and is immediately reflected. Is required. In this article, the managed tables are represented. The processing procedure according to the command request is detailed. The protocol between STP and the Inter-Network Management System is over Datalink X.25.

When a change or expansion of the signal network is required, the signal network routing specification operator maintains the consistency and synchronization of the routing table through the signal network monitoring data. Changes to the routing data must be performed. Therefore, the signaling network management system manages several signaling relays at the same time, so that data of each signaling relay switch can be changed separately for specific data, but in some cases, it is necessary to change the data of signaling relay switches at almost the same time. Modification methods include immediate processing and reservation processing.

Basically, routing data management function of signaling network has addition, modification, deletion, retrieval, activation and deactivation by routing data control command of remote signaling relay in signaling network management system.

This capability is a connected service that performs basic and multimode processing. Single mode provides the ability to handle single routing and handle multiple routing relationships.

The additional function may include adding new routing data related to the routing relationship for a node in the signal network, so that additional information may be added to the routing table or adding a completely new routing table.

The change function allows modification of existing routing data related to routing relationships within a particular node.

The delete function is inversely added. Routing data related to the routing relationship is deleted from the routing table.

The search function provides a method for requesting routing data from a specified signal point. It is possible to check between STP pay, signal relay switch and signaling network management system by record and table.

Activation initiates the use of defined routing data.

Deactivation is required to stop the service and to change the routing table.

The replication function of the table is used when a new signaling relay switch is installed by the network plan, when a large amount of data change request occurs due to a system failure in the signaling relay switch or a mutual network management system, or a table-level replication for table verification. Mutual replication is possible for the case where is required.

As above, the control function of the signal network management system is diverse and the multiple systems must be controlled and managed, so that the work seat function can be easily operated by the operator, and the input data can be generated after the verification is performed. .

Changes in routing specifications should be made available to the operator through a graphical task seat, since the operator must be able to identify them quickly and quickly.

In addition, it has a function to search and change by record unit table so that the data of routing specification can be checked at any time.

In order to understand the status of the specifications of the signal network, the analysis screen was able to grasp the overall report of the specifications of the signal network and the history report of the routing specifications by STP and the change history of the routing table through the work seat and the printer.

In conclusion, the process composition, processing method, and task seat were composed of the maintenance of routing specifications between the signal relay switch and the signaling network management system, the change of the routing table, and the management of routing specifications in the signaling network management system.

The STP module table 309 and the unit table 310 make a reference for routing specification management, and modules and units are managed and controlled by a maintenance function.

FIG. 4 is a flowchart illustrating the operation of the operator command selection in the operator task seat 202 as an overall flowchart for performing the routing specification management method in the signal network management system. The confirmed result may be output through the printer 203.

The specification management operator checks the signal network status at any time through the graphic work seat 201 to check the specifications of the signal network, and if the user wants to accurately grasp the state of the signal network, the operator checks the signal network specifications at the work seat 401. If the user selects a menu and wants to determine the remote STP routing data rate (403), a routing data search command 405 is performed. Otherwise, in order to grasp the SIGNOS-retaining routing specification data, the data retrieval function is selected in step 404. This process has a step of outputting the processing result to the work seat 416 in detail.

When the fault detection 406 of the signal network is detected, the searcher 402 of the upper level of the operator can be performed to determine the correct state, and when it is determined as the request for changing the signal network routing data (407), Do this. When changing the routing data of the signaling relay switch in which a failure is detected, if the routing data causes the routing failure of the adjacent signaling relay switch, select the reservation processing change method (409) to maintain consistency with the reservation processing method in each signaling relay switch. While changing the routing data. If it is determined that the failure is not, the routing data of the signal relay switch is immediately processed by the change processing command 408. The operation is completed, the process is completed by receiving the performance response message from the STP, reflecting the result to the database, and outputting the STP performance response reception and processing results to the work seat 416.

And if the signal network plan (410) is required to change, the upper search step 402 can be carried out to determine the correct state, the operator determines that changing the routing data is required to match the routing data in the signal network dimension In this case, the reservation processing change method 409 is selected to perform the change processing command while maintaining consistency in the reservation processing method to the related signal relay switch. Otherwise, if it is determined that the specification of the simple signal relay exchange is changed, the change processing command can be executed by the processing data 408 immediately by the corresponding routing data. The operation is completed, the process is completed by receiving the performance response message from the STP, reflecting the result to the database, and outputting the STP performance response reception and processing results to the work seat 416.

Next, data initialization (411) selection is a system initialization (411) of the signal network management system and the signal relay exchange period, or a data initialization operation performed by a table replication function performed when a complete recovery of the system is required due to the failure of the signal network. Has The initialization operation causes SIGNOS to replicate according to the initialization state 412 of the signaling exchange system. If the STP is initialized, SIGNOS replicates and stores it in the database (413) .If the STP is not initialized, SIGNOS creates initialization data of the signal network dimension (414) and transmits it to STP (415), You can replicate SIGNOS data in STP. The operation of the work seat is determined by the operator, and the work is completed by receiving the performance response message from the STP, processing the result in the database, and receiving the STP performance response and outputting the processing result to the work stone 416. The process ends.

5 shows the message flow between the signaling network management system and the signaling relay switching period.

Reference numeral 501 denotes an STP routing table search / replication command and a response message, and receives a search and duplication result message from the STP operation management system. The duplicated content is stored in the related table.

In order to immediately change specific routing data, when a SIGNOS specification management operator instructs a message flow that performs a routing table immediate processing change request 502, the OMS receives a message and converts it to Signaling Network Management (SNM) to notify it. The SNM reflects the routing table and notifies the OMS of the result.

OMS sends messages according to the interface specification between SIGNOS-SMX-1. After receiving the response message, SIGNOS changes the data in the network routing table and records the input data in the history management DB.

In order to change routing data of several STPs simultaneously while maintaining the consistency and synchronization of the signaling network, OMS receives and receives a message when a SIGNOS specification management operator instructs the message flow to perform the routing table reservation processing change request (503). Send a response and register the reservation message in the reservation table. A message whose activation time is reserved sends the execution command to the SNM at the reservation time, and if the reservation time for the reservation command is not registered, the reservation command activation is sent so that all the reserved messages can be executed at a specific time. At this time, the OMS receives the message, sends a reception completion response to SIGNOS, and activates and sends a message registered in SNM.

The SNM reflects the routing table and notifies the OMS of the result. OMS sends messages according to the SIGNOS-STP interface specification. After receiving the response message, SIGNOS changes the data in the network routing table and records the history data in the history management DB.

(504) When the routing table status change in the signal relay exchange and the routing data change in the OMS work seat are performed, the automatic output message is notified to SIGNOS in order to match the data, and the status of the routing data of the SIGNOS is changed and the routing specifications are changed. Will be At this time, the routing data change history is also recorded in the history table.

6 is a detailed flowchart of data initialization of FIG.

If the network routing specification configuration table initialization step is defined, it is divided into three steps.

In the first step, when the STP system is initialized to perform interworking with the signal relay switch of the signal network (601, 602) (603 to 605), the STP shape table (308 to 310) is duplicated (309, 310). A method 606 to 308 is stored in the configuration DB, and in the second step, when the signaling relay exchange also initializes the data of the routing tables 302 to 307 (610 and 611), the initial data is replicated in SIGNOS (612 to 615). By the way.

The third step is to create the initialization data (617 to 618) of the routing table (301 to 307) of the routing specification management operator network dimension of the signal network management system based on the shape data of the signal relay exchange (611) to the target signal relay exchange. Command to initialize (619,616,620).

7 is a detailed flowchart of the routing data immediate processing change command of FIG.

This is the system that shows how to change the immediate processing in SIGNOS to change the signal routing data. Changes in routing data in the signal network have a direct impact on the signal path and must be accurate and consistent. Therefore, the verification of input data is guaranteed as much as possible.

In order to perform the additional function 701 of the routing data, the first step is performed through the specification management work seats 202 and 204. When the immediate processing request is added for a specific target, the target, target STP, and target table are selected (702), and the routing data to be added is input. Process 207 should not have input data 703,704 for additional commands in association tables 302-307 (705,706). If the determination result is satisfied, an interface message is generated (712), and the message is transmitted to the third step STP (713).

The second step is performed through the specification management task seats (202, 204) to perform the search (710), delete (708) change function 709 of the routing data. When performing immediate deletion, change, or search for a specific target, the target, target STP, and target table are selected (702) and the routing data to be changed is input. Process 207 verifies that input data for the change command should be present in the related tables 302-307. If the verification result is satisfied, an interface message is generated (712), and the message is transmitted to the third step STP (713).

8 is a detailed flowchart of the routing data reservation processing change instruction 409 of FIG.

This is a schematic diagram showing how to change reservation processing in SIGNOS. When a series of routing data (302 to 307) is required for several signaling relay exchanges, reservation time can be registered to maintain consistency and synchronization. It is a routing specification management method to control. When the routing data is required to be changed during the operation of the signaling relay switch, the synchronization of the signal network can be maintained. The first step is to change the routing data reservation method through the task seats (202, 204, 207), and input data is selected as a reservation command. (801, 808) and the reservation time can be registered accordingly. Input data validation for changes 808 through 810 is validated (811,804) based on the data in the association tables 311,312, and the validated data generates a reserved command interface message (812).

The message generated in the second step is transmitted (813, 814) to the STP, and the transmitted message has a procedure of the reservation order registration (503) by the acceptance process of the STP. It sends an ACCEPT response to SIGNOS as a response message of STP. The specification management process 207 of SIGNOS outputs the results to the work seat 815, records them in the reservation processing tables 311 and 312, and manages 816 reservation command messages.

The control procedure 817 has an activation, deactivation, deletion, and retrieval function for the message reserved and reserved in the third step. In this case, the user registers a time registered message as a new time or performs a function of canceling the reserved message. This step inputs a reservation command control request in the work seats 202, 204, and 208 in the case of performing a control command on the message registered in 816. FIG. The input data can be the target STP, the scheduled job number, the group unit of the item number, and the record unit. The verification of the input data 818 performs a registration process on the reservation tables 311 and 312, and then generates an interface message (818, 819, 820, 822, 823, 824) and transmits it to the STP (825).

FIG. 9 is a detailed processing flowchart of a procedure 416 of receiving a response message in a work seat for a routing specification management command of SIGNOS from the STP of FIG. 4, which is a procedure of receiving 901 at the network connection unit 211. FIG. Incoming messages are immediately processed and the reservation destination is classified as a result and sent to the related process. The process 204 receiving the immediate response 902 message is a resultant 903 for the Routing Data Change Request command of FIG. 7 in a connected protocol structure. The task seat screen 203 outputs the request and the result according to the completion response and the error response 905, and in the case of the completion response, the state of the changed signal network is displayed on the graphic processing screen 202.

The process 210 that has received the reservation processing response 906 message is a result processing step 906, 907, 908 for a routing data change request command of FIG. 8 in a connectionless protocol structure. When the reservation message identical to the sequence number of the received response message is accessed (906) from the reservation table (209, 311, 312), and the request and result are output to the task seat screen 203 according to the completion response and error response (910), and the completion response. The state of the changed signal network is represented on the graphic processing screen 202 (910).

The procedure of 911 changes the contents of the signal network configuration specification DB 209 when receiving the completion response. In the history management DB 209 for the specification change, it is recorded (314) that the change of the immediate processing and the reservation processing is normally completed.

When the error response is received, it is recorded in the history management DB table 314 for the change of specification immediately and the reservation process change abnormally without changing the content of the signal network configuration specification DB 209. The message ended the STP response process for the reservation command is removed from the reservation table (311, 312).

10 is a step of receiving and processing a signal routing data change notification (1001) in a distributed STP. In STP, routing data change notifications fall into two categories. First, the Signaling Network Management Unit (SNM) 214 of the signaling relay switch performs routing data management through routing changes on the signaling network and traffic control during congestion. The status change status of the routing data is automatically output to the operation management subsystem (OMS) 213 to be grasped by the operator at any time, and the operation management subsystem (OMS) notifies the signal output network management system 211 to the automatic output message (1001). )do.

The automatic output message reception processing process 210 reflects the contents of the state change message of the signal network configuration specification DB 209 (1002, 1004, 1005). In the STP automatic output message processing method, the signal routing system manager can immediately grasp the status 1006 through the graphic task seat 201. Therefore, the signal manager of the signaling network management system may perform the mismatch situation of the signal path in the network dimension, and if abnormal data is found through the routing consistency verification, the routing control management may be performed by the method of FIG. 7 or FIG. 8. Secondly, when the OMS 312 changes the routing data, the changed information is notified to the signaling network management system. As the change in the distributed node is notified to the signal network management system (1001), the automatic output message reception processing process 210 reflects the change message content of the signal network configuration specification DB 209 (1002, 1004, 1007). do. Then, the changes are recorded in the specification change history management DB 209 (1009, 1010) that the OMS change is completed.

FIG. 11 is a description of the use of retained data of the signal network management system. The process of the signal network routing specification data management and the routing data retrieval command of FIG.
