Operation and Maintenance Department (QAP) in Q.753 of CCITT

MTP Routi as an application service of n 's Malntenance and Adnunistration Part

ng Verification Tests) and SRVT (SCCP Routing Verification Tests) are provided to verify the consistency of routing data. In order to do this, the user part of the Signaling Connection Control Part (SCCP) or more can start the function operation of the Transaction Capability Applacation Part (TCAP) and the Operation Maintenance Unit Application Service Element (OMAP-ASE). It is supposed to be. In particular, since this function is recommended to start at any of the distributed signal points, the verification procedure also has a procedure called distributed verification.

Highly available and highly reliable signaling relays (SMX-1), which are currently in development and commercial stages, have no user part beyond the SCCP. This feature means that MRVT and SRVT cannot be performed among the operations maintenance department (OMAP) functions. However, maintaining the consistency of routing data from the point of view of the signal network can greatly affect the performance and reliability of the signal network, so that the above functions can be performed so that the test step can be performed after a network failure or routing data change. It is necessary to do

In order to verify consistency in the signal network management system, the following two methods can be implemented. First, by requesting routing data to the signal points to be managed at the same time by the broadcasting method, the routing data is verified based on the response data. It is a way. This method has the option of requiring only the required routing data or all routing data after preprocessing. Second, it requires routing data as a signal point to start verification by a phased approach, and then requires routing data as extracted signal points by extracting the next routing signal point based on the response data. In this way, the routing to the desired signal point is verified. In this case, when the routing state is changed in the middle of the verification due to a time difference, the verification must be restarted.

Therefore, the present invention manages the signal network after confirming and matching the routing data of the signal points to be managed as a whole for the consistency of routing data in the signal network management system that concentrates and manages the highly reliable signal relay switch (SMX-1). Its purpose is to provide a method for verifying consistency of routing data that is locally verified in the system.

In order to achieve the above object, the present invention provides a method of verifying routing data consistency applied to a signal network management system connected to signal relay exchanges, wherein the contents of the specification-related table are matched between the signal relay switch and the signal network management system. First step; A second step of verifying a routing situation and an error situation between signal points input by an operator using routing specification data maintained by a database manager; And from the signaling point to the service signaling point according to the signaling point that provides the global name translation service input by the operator using the signal connection control unit (SCCP) routing control data maintained by the database management unit The third step is to verify the routing and error conditions.

Hereinafter, with reference to the accompanying drawings will be described an embodiment according to the present invention;

There is a difference between the verification method in the signal network management system and the verification method in the distributed signal points themselves. The verification initiated by the user part of the signal points themselves generates only the message based on the routing data maintained by the signal points and passes through the next routing signal point, so the actual state between the signal points can be ignored. However, in the signaling network management system, it is necessary to check whether these messages can be correctly transmitted according to the routing state, and for this purpose, it is necessary to determine whether the states of the signal link, the signal link set, and the target signal points coincide. This is a matter to consider when implementing routing data consistency verification. In the present invention, it is possible to verify the routing state and the connection state between signal points.

The present invention is described in detail as follows.

1 is a configuration diagram of a signal network management system that centrally manages a signal relay switch.

The signal network management system 101 includes six subsystems of the user connection unit 102, the network connection unit 103, the system management unit 104, the database management unit 105, the specification management unit 106, and the network management unit 107. It consists of. The connection with the operator is handled by the user interface 102, and the network interface 103 handles the interface with the signal relay exchanges via the X.25 data link. As a partial function of the specification management unit 106 of the present invention, the function is performed through an interface with the user connection unit 102, the network connection unit 103, and the database management unit 105. In the common line signaling system 108 to be managed, four signal relay exchanges composed of two pairs are formed in a quasi-corresponding mode.

2 is a functional configuration diagram of a signal network management system for routing data consistency verification function to which the present invention is applied, and 201 is an internal functional unit of a signal network management system related to routing data consistency verification.

The specification manager 106 includes a routing specification checking unit 208, a routing specification consistency verification unit 209, a signal connection control unit routing control verification unit 210, and other user connection unit 202 and database management unit 203. Each subsystem of the network connection 204 is the same as that of FIG. The work seat 207 is divided into graphic work seats, dummy work seats, and integrated work seats, which are used in the signal network management system, and are in charge of the interface at the user connection unit 202. The signaling relay switch that is actually managed is composed of a local management system (0MS) and a signaling relay switch. The interface between the signaling network management system and the signaling relay switch is made between the function of the network connection 204 and the network connection of the local management system 205. The database manager 203 is a function of managing all data handled by the signal network management system. The database manager 203 also accesses the signal network configuration specification database related to the present invention through the database manager.

The network connection unit 204 is responsible for interworking with the management target signal relay switch, controls interface verification and message congestion, and monitors a connection state with each signal relay switch. The operation maintenance unit 205 of the signal relay switch sends an interworking and local control command with the signal network management system to the target 206 of the signal relay switch SMX-1 and monitors the status of the signal relay switch. Perform the function. The target 206 of the signal relay switch indicates a signal relay switch, and the signal network management system does not directly control the signal relay switch but accesses the signal relay switch through the operation maintenance unit 205 of the signal relay switch. Can be. The work seat 207 is a work seat used by the operator and is divided into a dummy work seat using a dummy terminal and a graphic work seat using a graphic terminal, collectively referred to as an integrated work seat. In addition to the work seat function, the graphic terminal also outputs the network status to the graphic display screen, so that the operator can easily recognize it.

The present invention is composed of the functions of the routing specification verification unit 208, routing specification consistency verification unit 209, signal connection control unit routing control verification unit 210.

The routing specification verification unit 208 corresponds to a preprocessing step of routing data consistency verification, and performs a function of matching the contents of the specification-related table between the signal relay switch and the signal network management system. Data matching between the two systems is an essential prerequisite for the verification function. If a discrepancy is found when checking the routing specifications, the operator is notified and terminated. Verification was done by checking only specific records and by table.

The routing specification consistency verification unit 209 performs the same function as the MRVT of the operation maintenance unit (OMAP), and the function is activated through the user connection unit, and the verification is performed on the specification data maintained by the database management unit 203. This function verifies the routing status and error status between signal points input by the operator. There is no actual interface with the routing specification checker 208, but it is made by the operator to check the error situation generated when the function is performed with the signal relay switch.

Signal connection control unit Routing control verification unit 210 performs the same function as the SRVT of the operation maintenance unit (OMAP), similar to the function of the routing specification consistency verification unit 209, the difference is that the operator's input translation It is to input the signal point providing the service and the general name to be verified. The target signal point is a signal point extracted through the hierarchical name translation, and verifies the routing and error conditions from the translation signal point to the service signal point.

3 shows a table relating to the present invention from the signal network configuration database, and shows the configuration relations and the relations between the states.

The signal link aggregation table 301 represents a junction of connected links between signal points, and the signal link table 302 shows a configuration of links connected between actual signal points. The destination signal point table 303 displays the configuration of signal points accessible by a specific signal relay switch (SMX-1) and their states, and the signal route table 304 actually sets a link set accessible to the destination signal point. This table shows the routing status by specifying. The global title translation table 305 is a table maintained at the signal point providing the global title translation service, and specifies the destination signal points for the global title, and the status of these destination signal points is specified in the service subsystem table 306. Lose.

The compositional relationship of the above tables is not constructed independently, but is maintained organically through the relationship with each other. The order of adding the signal network specification is in the order of link set, link, destination signal point, and route, and in relation to SCCP, it is generated in the order of service subsystem and general name in the above order. A relationship such as 307 to 309 indicated by solid lines indicate actual configuration relationships, and 310 to 312 indicated by dotted lines indicate state relationships between components.

In other words, the link set configuration relationship 307 represents a link set to which each link of the link table belongs and a link set used when routing to a target signal point in the routing table. The configuration relationship 308 of the destination signal points is that the neighbor signal points of the link aggregation table, the destination signal points of the routing table, and the signal points of the service subsystem table are associated with the signal points of the destination signal point table. 309 shows the relationship between the routing point signaling point and the subsystem number of the service subsystem in the global title translation table. 310 denotes a state of the link aggregate according to the states of the links. The link aggregate is activated when more links than the service link limit of the link aggregate table are activated. 311 denotes a state to a signal point according to a link aggregation state. The state of the destination signal point table 303 is affected by the routeable link sets of a particular signal point, and the state of the signal route table 304 represents the routing state through each link set. 312 denotes the state of the service signal points according to the routing situation, and the signal point state of the service subsystem table 306 coincides with the state of the destination signal point table 303.

The present invention verifies the routing to a specific destination signal point by using the configuration relationship between such tables.

4 is a flowchart illustrating a routing data consistency verification process according to the present invention.

When a routing data consistency verification command is received from the operator working in the integrated task seat 207 through the user connection unit 202 (401), the command and parameters received from the operator are interpreted (402). Verification of parameters verifies the required parameters for each verification step.

Then, as an essential process of routing data verification, it is checked whether the routing data is consistent by checking whether the routing data maintained by the signal relay switch and the signaling network management system is consistent in the specification related table (403).

As a result of determining whether the routing data is consistent, if the routing data is inconsistent, an error content including the cause is notified to the operator and terminated (405). If the routing data is consistent, the type of the input command is determined (406).

As a result of the determination of the command type, the verification of routing specification consistency command verifies the consistency of routing specifications such as the physically connected links between the signaling relay exchanges, the status of the link aggregation, and the root status logically connected between the signaling relay exchanges. Later (407) it is determined whether the routing error (408), if the routing error is notified to the error content including the cause and the operator terminates (405), if not the routing error is terminated immediately.

As a result of the determination of the command type, if the signal connection controller routing control verification is verified, the signal connection controller routing control for verifying whether the state of the route by the global title translation and the global title translation service status match is verified (409). This is to verify the routing to provide the global title translation service. The global title entered by the operator is verified. Thereafter, it is determined whether the signal connection control unit routing control error (410), if the signal connection control unit routing control error, notifies the operator of the error content including the cause and terminates (405), and terminates immediately if the signal connection control unit routing control error is not. .

5 is a detailed flowchart of a table checking process before routing data consistency verification according to the present invention.

The operator commands verification of the consistency of routing data in the integrated work area through the user interface. The routing data consistency verification function, activated by the operator's command, verifies the commands and parameters entered. The parameter consists of a signal point number or a generic name. In the verification phase of routing data consistency verification, there are differences in the tables that are checked according to the command type.

That is, when receiving a routing data consistency verification command from the operator (500), the received command and parameters are interpreted (501). At this time, the actual parameter verification for each command is performed in each function. Subsequently, the type of command is determined (502), in the case of the routing specification consistency verification, an interface message (link set, link, signal route, signal destination point table) is generated for the parameter of the table to be checked (503), and signal connection In the case of the controller routing control verification, an interface message (link set, signal route, general name, and subsystem table) is generated for the parameter of the checked table (504).

After that, the interface messages generated for the given parameters are accumulated in the interface message queue, and are transmitted to the corresponding signal relay switch according to the order of generation and checked with the received data.

That is, after generating the interface message queue and storing the generated interface message (505), the timer is driven when the message is transmitted to the signal relay switch (507) to determine whether there is a response to the message according to the type of stop of the timer. (508). If it is determined that the stop type of the timer is not received due to the elapse of the time limit, the operator may be notified of the error because the link status of the signaling network management system and the signaling relay exchange period or the related function abnormality of the signaling relay switch may be the cause. 511) If the stop type is a response of the requested message, it is determined whether the response message sent from the signaling relay switch is a normal response (509). As a result of the determination, if the response is an error, the operator is notified of the error contents including the cause (511). If the response is normal, the operator checks whether the data in the table corresponding to the contents of the message is consistent with the data maintained by the signaling network management system (510). ). As a result of the check, if the data is inconsistent, error information including the cause is reported to the operator (511). If the data are matched, the interface message queue is checked for empty (512). If the data is not empty, the message transmission process (506) is repeated. The process is performed until all generated interface messages are acknowledged. This process is an operation to satisfy the precondition of routing data consistency verification and performs verification function after checking whether the contents of all tables to be verified match.

After checking the contents of the table, the type of the command is determined (513) to perform a verification function according to the command.

6 is a detailed flowchart of a routing specification consistency verification process according to the present invention.

The start of the function is performed by the operator after verifying the input signal start point and the target signal point (601). The existence of each signal point is confirmed by using the destination signal point table, which may not be the signal relay switch. (602). If any one of the two signal points does not exist, a non-existent signal point is input (603) to notify the operator of the error and terminates (604). If two input signal points exist, a start signal point is added to the verification list as an initial setting step of the verification function, and the routing length value is initialized to 1 to confirm the length of the routing path (605). The routable table is used to extract the routable link junctions from the start signal point to the target signal point (606).

The domestic signaling network consists of two signaling relay switches in full mesh (Ful1-Mesh), so routing at a specific signaling point is possible through up to three link junctions. Therefore, it is determined whether the number of extracted link junctions is in the range of 1 to 3 (607), and if it is not within the range, a link junction number error is generated (608) and the operator is notified (604). The extracted linkset and the number of linksets are stored in a temporary buffer and the linkset counter is initialized (609), after which the routing to the destination signal point is verified.

The core of this function is as follows.

After that, a test state such as a link set counter order and a state to a destination point through the link set is extracted (610). This is to extract the routing status maintained in the signal route table in order to determine whether or not the routing status matches each result. Next, a regression search is performed to verify the routing of each step through the link set and the test state extracted in the above process (61l). Subsequently, if it is determined that the link set counter and the link set number are the same (612), if it is not the same, the link set counter is increased (6l3), and then the process is repeated from the process of extracting the test state (610). When this is done, the verification list for each link set is output (614). At this time, the regression search performed at each step is not terminated even if the system is abnormal, that is, when the database is not accessible, and the error situation found during the search is temporarily stored and notified to the operator when the verification result is output. The output to the operator is made through the integrated task seat, and the operator can easily recognize the routing status through the verification list and connection link set for each routing pass and their status.

7 is a detailed flowchart of the regression verification process according to the present invention.

This method is used in the routing specification consistency verification and the SCCP routing control verification. The regression search is called again inside the regression search to perform the search to the next step.

First, an adjacent signal point is searched through a link set set using the link set table 301, and a state is searched using the destination signal point table 303 according to the found neighbor signal point (701). Since the overall state needs to be determined by combining the routing states for each step, the stepped state is reflected through the OR operation of the routing state and the entire routing state of adjacent signal points (702).

Subsequently, it is determined whether the neighboring signal point during the verification process and the target signal point input by the operator coincide (703). When the neighboring signal point and the target signal point coincide, the test state and the entire routing state are compared to determine whether the routing is consistent ( 704). If these two states match, it is a normal situation, and notifies the operator of only the routing pass and the state and returns (705). If the two states do not match, an error condition indicating that a routing mismatch occurs is returned and the step-by-step verification signal points maintained in the verification list are output together (706).

If the adjacent signal point and the target signal point do not coincide with each other, it is an intermediate signal point. Therefore, after increasing the routing length value by 1 (708) and determining whether the boot length is greater than 4 (709), the network configuration is greater than 4 Since the length of the routing path is exceeded, it is returned after notifying the operator (710). If the routing length value is less than 4, it is checked whether there is an adjacent signal point in the verification list (711). As a result of the check, if there is a routing loop, the operator is notified and returned (712). This is to verify the case of rerouting once rough signal point. If there is no adjacent signal point in the verification list, replace the starting signal point with the adjacent signal point, add the adjacent signal point to the verification list (713), and then extract rootable link junctions from the newly replaced start signal point to the destination signal point. (714).

Then, it is checked whether the number of extracted link sets is in the range of 1 to 3 (715). If the number of extracted link sets is not within the range, a link set number error is generated and the operator is notified and returned (716). The stored link set and the number of link sets are stored in a temporary buffer and the link set counter is initialized (717).

Thereafter, a regression search for verifying each step routing is performed (718). Next, if it is determined that the number of link aggregation counters and link aggregations is the same (719), if it is not the same, the link aggregation counter is incremented (720), and then repeated from the regression search process 718 and repeated as many times as the number of available link sets. Returns ground.

The regression search of FIG. 7 returns to the previous stage when the adjacent signal point and the destination signal point coincide with each other and the routing verification is completed normally, and when an error situation such as routing length exceeding or routing loop is found. . The error situation to verify is similar to that of MRVT, but has the following differences in verification method. First, the MRVT is verified through a certain test message and a response message, but in the present invention, the MRVT is verified by combining the data of the signal relay exchanges. Secondly, MRVT does not need to check the routing status in the middle of message transmission, but the present invention differs in that it also checks the physical connection state because it is verified locally.

8 is a detailed flowchart of the SCCP routing control verification process according to the present invention.

The operator verifies the existence of the entered blanket name by verifying the signal point and the blanket name input by the operator (801). If the overall name does not exist, the operator is notified of the error content including the cause and terminates (802). If the overall name exists, the translation service of the entered overall name is performed (803). This is performed using the global title translation table 305 in the same way as the global title translation service provided by the signal relay switch.

After the global title translation, the subsystem table 306 is used to check the existence of the subsystem (804). If the subsystem does not exist, the operator is notified of the existence of the subsystem and terminates (802). The test state to be verified is extracted (805). At this time, the start signal point becomes the signal relay switch number input by the operator, and the test signal is extracted by adding the state of the target signal point and the subsystem by using the target signal point as the target signal point extracted after the translation of the global title.

The SCCP routing control verification function verifies the routing only when the routing state of the target signal point is available (determining whether the test state is available) (806). Report unavailability and terminate (807).

If the test state is available, the start signal point is added to the verification list as an initial setup step of the verification function, and the routing length value is initialized to 1 to confirm the length of the routing path (808). In operation 809, routingable link sets are extracted from the starting signal point to the target signal point using the routing table.

Since the domestic signaling network consists of two pairs of signal relay exchanges (Ful1-Mesh), routing at a specific signal point is possible through up to three link aggregations. Therefore, it is determined whether the number of extracted link sets is in the range of 1 to 3 (810). If the number of extracted link sets is not in the range, an error is generated and the operator is notified (802). The number of sets and link sets is stored in a temporary buffer and the link set counter is initialized (811).

Thereafter, a regression search for verifying each step routing is performed (812). After that, if it is determined that the link set counter and the link set number are the same (813), if it is not the same, the link set counter is incremented (814), and then repeated from the regression search process 812, and repeated as many times as the number of available link sets is performed. The verification list according to each link set is output (815). At this time, the regression search performed at each step is not terminated even if the system is abnormal, that is, when the database is not accessible, and the error situation found during the search is temporarily stored and notified to the operator when the verification result is output. The output to the operator is made through the integrated task seat, and the operator can easily recognize the routing status through the verification list of each routing pass, the link link junction, and their status.

Therefore, the present invention carried out by the above processing procedures, maintain the performance of the network to a certain level through the local verification of the signal network management system when the test procedure is required, such as message loss due to changing specifications or routing failure It is effective.

If there is no neighboring signal point in the verification list, the starting signal point is replaced with the neighboring signal point and the neighboring signal point is added to the verification list. Extracting a routable link set from a newly replaced start signal point to a target signal point later; If the number of extracted link sets is within the predetermined range, if it is not within the range, an error is generated and the operator is notified, and if it is within the range, the extracted link sets and the number of link sets are stored in the temporary buffer. A tenth step of performing a regression search for storing and verifying each step routing after initializing the rung set counter; And determining whether the link set counter is equal to the number of link sets, and if it is not the same, repeating the regression searching process of step 10 after repeating the increase of the link set counter, and returning if the repeated number of link sets is repeated. Routing data consistency verification method in a signal network management system comprising a.
