Description

Apparatus and Method for Leased Line Provisioning by Interworking with NOSSs (Network Operation Support Systems)}

The present invention relates to a dedicated line configuration device and its operation method, and more particularly, to define the interworking work rules between the network operation management system involved in the configuration of the leased line to automate the work request and result notification process between the operation personnel unnecessary The present invention relates to a circuit configuration interworking processing apparatus and a method of operating the same, which can enhance the reliability of a dedicated communication network and increase the efficiency of a complex configuration management function by providing work exclusion, shortening of work time, and accurate work order.

In the conventional dedicated communication network configuration, a subscriber subscribes to a sales management system and installs a user-network interface (UNI) unit of a dedicated line, and a dedicated digital line distribution device network (DCS: Digital). DCS management system that manages Network-Network Interface (NNI) through Cross-Connect System is in operation.

Conventionally, the sales management system and the dedicated line management system are linked to each other, and take over the necessary work, and perform the UNI unit work in the dedicated line management system, and offline (telephone or fax, etc.) interlocked with the DCS management system to the DCS network. Work was performed on. This process is easy to link because the subscription and UNI unit is relatively simple, but the work link between UNI and NNI units is complicated and the changes may occur frequently in business processes. Interworking management has occurred frequently, which causes the interruption of subscriber service, and it takes a lot of time to process work. In particular, in recent years, the demand for leased lines due to the spread of the Internet and the changes (speed change, location change, etc.) for these frequently occur frequently, and thus the situation is urgently required.

An object of the present invention for solving the problems of the prior art as described above is to configure a dedicated line by maintaining the interlocking rules and work processes according to the work history between the network operation management system managing each of the UNI unit and the NNI unit in the dedicated line opening process. The purpose is to provide functionality quickly and efficiently.

Hereinafter, a method of configuring a dedicated line by interworking with a network operation management system according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram illustrating a general leased line configuration to which the present invention is applied, and a general leased line configuration is largely divided into a UNI unit 101 and an NNI unit 105, and in detail, subscriber end devices 102 to 102-n. , TE: Terminal Equipment, DSU, CSU, etc.), PCM (Pulse Code Modulation) Station 103-103-n, Digital Line Distribution Device 106, DCS: Digital Cross-Connect System.

As shown in FIG. 1, a dedicated communication network is largely divided into a UNI unit 101 and an NNI unit 105. In the distance concept, the UNI unit 101 includes a user to a contact point from a network to a component. The concept is composed of the subscriber end devices 102 to 102-n to the PCM end station devices 103 to 103-n. The NNI unit 105 is composed of a mesh-type DCS network using a plurality of DCS 106. In general, a transmission path is configured between the DCS 106 in advance, and when a subscription request is received from a user, a solid line is formed from the telephone terminal station device to the subscriber end devices 102 to 102-n. After connecting to the DCS 106 at (103 ~ 103-n), the cross-connection configuration by the channel unit using the DCS network is opened by opening.

2 is a conceptual diagram of an interworking configuration between network operation management systems interlocked with and associated with the opening of a dedicated line according to an embodiment of the present invention. The entire system is largely a sales management system 210 and a dedicated line management system 220. , DCS management system 230, and they work in conjunction with each other.

The sales management system 210 is a system for managing leased line subscription contents and service charges from a customer, and does not manage physical configuration information about a line. Management offices include the competent telephone offices that connect the solid line to the station equipment, service information (such as line speed and method), and information for billing. Therefore, since the sales management system 210 is not related to the actual line configuration, there is no part controlling the dedicated communication network, and the work completion information and the work date and time information on the line configuration are interlocked with the dedicated line management system 220. Manage only

The sales management system 210 receives a subscription for a private line (new configuration, change of an existing line, termination of an existing line, etc.) from a customer in the opening reception program 211 and stores it in its own database 213. The part to be reflected in the facility side rather than the side is transmitted to the dedicated line management system 220. At this time, the socket-based interlocking servers 212 and 221 for interworking with both systems 210 and 220 are operated to exchange desired information according to a predetermined data structure. The details to be transferred from the sales management system side interworking server 212 to the dedicated line management system side interworking server 221 include a leased line service type, speed, subscriber end device location and jurisdiction telephone station, work completion desired date and time, and work type ( New, terminated, changed).

The interworking servers 212 and 221 store the details of the exchanges in the respective regional databases 213 and 224 so that subsequent operations can be performed. The regional center opening processing program 222 in the leased line management system 220 selects the telephone stations to be routed through the leased line and determines whether it is via the DCS network based on the details requested for interworking. In this case, since the competent telephone company of the place where the subscriber end device is located is already designated and delivered by the sales management system, only the other telephone stations to pass through need to be designated, and the telephone company opening processing is performed based on the contents recorded in the database in the dedicated line management system. The program 250 receives the work order requested by the regional center opening process program 222 online, and records the related information in the database after performing a work such as configuring a physical subscriber line section or connecting the PCM-DCS.

In addition, if work is also required in the DCS 260 part, it is specified that the interworking from the regional center opening processing program 222 to the DCS management system 230 is necessary to reflect the result of the telephone station opening processing program 250 to interwork. Deliver details.

The job transfer to the DCS management system 230 can be performed only when the incoming point to the DCS network and the withdrawal point from the DCS network are designated as shown in FIG. 1. The entry and withdrawal points into the DCS network are designated by inputting the PCM-DCS connection information of the telephone stations at the front and rear ends of the DCS network in the telephone station opening processing program 250 of the dedicated line management system.

On the other hand, the interworking between the dedicated line management system 220 and the DCS management system 230 when the interworking server 223 installed in the dedicated line management system 220 needs to interwork, the DCS management system 230 After the work history is stored in the database 231, the work is progressed by the DCS line configuration program 232, and when the DCS work is completed, the work history is stored in the database 231.

The DCS line configuration program 232 of the DCS management system 230 refers to the DCS facility and line usage information recorded in the database 231 for interworking request and the DCS line required to configure one line. It selects and performs cross-connection configuration by channel unit for each selected DCS and reflects the result in the database.

The server 223 for interworking with the DCS management system in the leased line management system 220 is close to each other unlike the interlocking servers 212 and 221 for interworking between the leased line management system and the sales management system. Because the data is connected, there are many parts to be reflected by referring to the dedicated line management system, so the data is not exchanged based on sockets, but the database is linked to both of the databases 224 and 231 at the same time. . Therefore, when a record to be transmitted from the leased line management system to the DCS management system occurs, the request information is generated by referring to the leased line management system side database 224 and the DCS management system side database information 231 is generated. Extracts and passes the request by inputting directly to the DCS management system-side database 231 through a determination process. In contrast, when the request is completed in the DCS management system, the DCS management system-side database 231 is referred to. The completion result and the facility reference information are modified in the dedicated line management system side database 224.

The dedicated line management system 220 and the DCS management system 230 manages dedicated line related facility information and DCS related information as a database, respectively, and serve to control the UNI unit and the NNI unit of FIG. 1. Facilities that can be controlled remotely are mainly controlled using X.25 networks or TCP / IP networks, and the results of remote control can be directly reflected in the database, but facilities that cannot be controlled remotely perform manual processing and database updates. shall. Most of the station devices of the leased line management system are impossible to remotely control, so that both the facility work and the database update work are handled in parallel, and the DCS devices of the DCS management system are all remotely controllable. Is performed.

3 is a diagram illustrating the types of jobs requested by the DCS management system 230 from the dedicated line management system 220 illustrated in FIG. 2.

First, 'New Configuration' is requested when a new leased line is applied from a customer when it needs to go through the DCS network, and 'Release' is a request to remove the DCS network configuration when a request for termination of use of the circuit is in use. . In addition, the 'configuration change' requests when a customer wants to change a line that is being used, that is, when a speed up or slow down or a change in the location of an end device is required, and a line to be reconfigured separately from the existing line in the DCS network is requested. . At this time, it is not possible to directly change the existing line to the changed line, and the service is minimized only when the customer wants to change it, and the reason for configuring the line to be switched in advance is to prevent the lack of facilities at the desired time. to be. In addition, the 'termination of change' is a task of requesting the removal of unnecessary existing line after the time point at which the new line configured in the change configuration is actually opened.

With the above four work request classifications, there are some prerequisites for processing various functions performed in the dedicated circuit management system opening processing center. The work related to the termination of the circuit opening interworking shall be designated as the final work and requested. The reason is that the revocation operation is performing a physically irreversible operation, and the cancellation request for the configuration-related operation as well as the revocation request from the customer must be treated as the revocation request. For example, if the opening center needs to reassign a transit country after a new configuration request, it must send a request to revoke an existing new configuration request, ensuring that no other modifications will occur until the subscriber line is actually serviced. Since there is no absence, the request for termination of the initial new configuration shall be after the last circuit opening. This will be explained by giving an example for each work request.

4 to 7 are diagrams illustrating an operation type requested between a dedicated line management system and a DCS management system according to an embodiment of the present invention, and operations in a DCS network performed at this time.

4A to 4D are exemplary diagrams of operations in the dedicated line management system and the DCS management system in the case of the 'new configuration', and FIG. 4A is a state in which an opening process program is designated via each telephone station and DCS, and FIG. 4B is In the call center A, the subscriber segment configuration and the PCM-DCS segment are connected to each other to designate a point of entry into the DCS network. FIG. 4C is similar to FIG. 4B, and the caller B specifies the point of call to the subscriber segment and the DCS network. FIG. 4D is a time point in which an interlocking detail of actually connecting an incoming point of DCS1 and an outgoing point of DCSn to the DCS management system has been delivered. At this time, the available DCS from DCS1 to DCSn (sometimes via multiple DCSs) is shown. Connect to form a line. In this case, the circuit configured in the DCS network has a NEW delimiter in the circuit routing information, so that in the subsequent change processing, two circuits may exist in one dedicated circuit.

5A to 5D are exemplary views of a 'termination' request, and FIG. 5A is a time point at which a termination request is received in a dedicated line management system, and FIGS. 5B and 5C are diagrams illustrating a disconnection of a UNI interval from telephone stations A and B, respectively. As a situation, when the state of FIG. 5C is confirmed, the DCS management system requests to terminate the configuration of the DCS network. As a result of the operation of FIG. 5D, the connection state between the DCSs is disconnected. As mentioned earlier, the service is already suspended because the termination operation is requested to be interlocked when the final termination of the UNI section is completed. In addition, the line actually terminated in the DCS network when the 'termination' request is a line divided as NEW in Figure 4d. This explanation will be omitted since it will become clear when the change configuration or the change cancellation operation is performed.

6A to 6D are exemplary diagrams illustrating a 'change configuration' operation of a line, and FIG. 6A shows that there is a dedicated line (NEW) already in use. A change configuration causes a line change through a new line configuration operation for a number of change requests, such as a request for a speed change (for example, a 128K to 256K speed up or slow down) on an existing line, or a transfer request due to a change in the location of a subscriber end device. It means work. 6B and 6C show a state in which a telephone line A, B section is configured as a new line in the dedicated line management system. Of course, in case of installation change, the telephone station itself may be changed to another telephone station. Although the new circuit is configured, the service of the existing circuit must be maintained until the change date designated by the user. When the operation up to FIG. 6c is completed, a new circuit is configured in addition to the existing circuit in the DCS network by requesting a 'change configuration' task to the DCS management system. At this time, by configuring the circuit to be changed in the DCS network in FIG. 6d, marking the old line as OLD, and naming the new line again as NEW, having one line number (ID) in the DCS management system. Stores information by distinguishing between old and new lines. The reason for storing this is that when a change configuration is canceled, a new line (NEW) must be terminated, and an existing line (OLD) must be terminated when the change configuration is finally made.

7A to 7D are exemplary views of a 'change cancellation' operation, and FIG. 7A is the same as a time point when the 'change configuration' operation in FIG. 6D is completed. When the change is finally confirmed in this state, the existing line of the UNI portion, which is the dedicated line management system management section of FIGS. 7B and 7C, is first terminated, and at this point, the change is made to remove the existing line portion existing in the DCS network. Termination is requested. FIG. 7D illustrates a state in which a task of terminating the existing circuit OLD of the DCS network is completed based on the requested details. If a change cancellation operation is required instead of the termination of the existing circuit in FIG. 7A, the new circuit may be terminated by forwarding a 'termination' request to the DCS management system. In this case, the new circuit (NEW) should be closed and the existing circuit (OLD) should be named NEW again to maintain consistency.

FIG. 8 is a data structure diagram for transferring details to be requested to a DCS management system from a dedicated line management system according to an embodiment of the present invention. The main management items are line numbers (IDs), to complete opening operations for the same line. Serial number, request type, entry point to DCS network, withdrawal point, line related information (speed, transmission method, etc.), work related information (time transmitted from dedicated line management system, work status) This is necessary. The information necessary when the DCS management system completes the request work and extracts the completion information from the dedicated line management system is carried out as a result of the request from the DCS management system when the request details are completed and the status information related to the work, and the facility for the changed DCS network. Information such as passthru DCS and channel cross-link configuration information.

9A to 9D are flowcharts illustrating an interworking form and a work order to be delivered when an opening interworking is performed between the two systems according to an embodiment of the present invention.

Fig. 9A is a flowchart showing details of work to be performed upon initial request in the dedicated line management system. When the initial interlocking request signal is input in step S901, the request type is determined in step S902.

As a result of the determination in step S902, in step S903 to step S906, the operation suitable for the type is performed, and 1 (new configuration, step S903) and 3 (change configuration, step S905) respectively send out interlocking requests. , 2 (cancellation, step S904) and 4 (cancellation of change, step S906), which are delivered at the time point where the UNI and NNI sections are finally completed, make the physical demolition work always successful. As mentioned earlier, if the termination-related work is interlocked instead of the final completion point, there is a disadvantage that the work process becomes complicated when modifying or canceling it.

FIG. 9B is a flowchart showing when a correction request is required after the interworking request is made to the DCS management system initially. The correction operation may be frequently made due to a change request of a user or a condition of an opening center operator and a telephone station facility operator. have.

First, in step S910, when a correction operation is required, in step S911, it is determined whether the necessary correction operation is a simple cancellation operation.

If the determination result in step S911 is a simple cancel operation, then in step S912, the type of the previous operation is determined.

As a result of the determination in step S912, when the previous job is 1 (new configuration) or 3 (change configuration), it is determined in step S914 whether the previous job status is in the standby state, and if it is in the waiting state, in step S915, DCS Since the job has not been started in the management system, the previous request is simply deleted, and in step S916, a job for requesting 2 (cancellation) is performed. Since the cancellation request is performed at the final completion of all work, it is not requested to interlock immediately upon cancellation. On the other hand, if the determination result in step S914 is a standby state, the process immediately proceeds to step S916.

On the other hand, if the previous operation is not 1 or 3 as a result of the determination in step S912, cancellation of the cancellation and change cancellation is impossible in step S913. In other words, there can be no cancellation because the cancellation request is performed at the end of every task.

On the other hand, if the result of the determination in step S911 is not a simple cancellation operation, in step S917, a job for correcting the existing request job is performed. First, in step S918, the previous job is 1 (new configuration). Determine whether or not.

As a result of the determination in step S918, if the previous job is 1, it is determined in step S919 whether the previous job state is in the standby state. As a result of the determination in step S919, if it is in the standby state, after deleting the previous request in the same manner as the simple cancellation operation in step S920, in step S921, after increasing the serial number of the operation to be corrected (new configuration or change configuration); , Perform a work commission.

As a result of the determination in step S919, if the previous working state is not the standby state, the flow proceeds directly to step S921. In this case, since there is a recent request, the work processing result of the previous request is ignored and the result of the recent case is maintained.

On the other hand, if it is determined in step S918 that the previous job is not 1, it is determined in step S923 whether the previous job type is three.

As a result of the determination in step S923, if the previous job type is 3, the operations in the same manner as in steps S919, S920, and S921 are performed in steps S924 to S926.

If the previous operation is not 3 as a result of the determination in step S923, the correction for the cancellation and the change cancellation is impossible in step S927.

9C is a flowchart showing the operation at the end point in the dedicated circuit area opening center, which will be described below.

First, in step S940, when no line termination work is required for the DCS section, an end process is performed. In step S941, the necessity of deleting the DCS section is determined.

As a result of the determination in step S941, if not necessary, the process is terminated in step S942. If necessary, in step S943, it is determined whether or not it is the first cancellation request.

As a result of the determination in step S943, if it is the first cancellation request, step 2 (2) is requested in step S944.

On the other hand, as a result of the determination in step S943, if it is not the first cancellation request, in step S945, it is determined whether it is a cancellation request for the existing line OLD after the line change operation, and if it is a change cancellation request, in step S946, 4 ( Request the termination of the change).

As a result of the determination in step S945, if it is not a change cancellation request, the operation is caused by a cancellation request generated during a series of request operations, and in step S947, 2 (cancellation) is requested to perform the cancellation of the existing request.

9D is a flowchart illustrating operations performed in the DCS management system after requesting interworking request from the dedicated line management system to the DCS management system.

First, in step S950, when a DCS work request is input after interlocking, in step S951, it is determined what type of request is.

As a result of the determination in step S951, if it is 1 (new configuration), in step S952 to step S954, after checking whether there exists a new (NEW) line of the same line number (ID), if it exists, the line configuration operation is terminated. And mark as NEW. If a NEW line of the same ID does not exist, the line is simply configured and then marked as NEW. In this case, the reason for distinguishing the lines of the same ID is to perform the pre-execution when the cancellation of the existing case is required in the subsequent request in consideration of the state in which the previous request is in progress when the corrective work request of FIG. 9B is performed.

On the other hand, if the request type is 2 (termination) as a result of the determination in step S951, in step S956 and step S957, only the NEW line termination operation in the DCS network is simply performed.

On the other hand, if the request type is 3 (change configuration) as a result of the determination in step S951, in step S958 to step S960, the DCS management system changes the line set to NEW to OLD, and then configures a new line to make it NEW. To be prepared for future work.

On the other hand, if the request type is 4 (change cancellation) as a result of the determination in step S951, only the line marked OLD is canceled in step S961 and step S962.

In this way, when the opening work for a dedicated line is organized, it may be possible to request a manual interworking or a non-regular repetitive interworking request in the past, and set rules to solve the complexity of the opening work by interworking between systems. It will be a great help to improve the reliability of the network configuration.

It will be apparent to those skilled in the art that various changes, modifications, or adjustments to the above embodiments can be made without departing from the spirit of the invention. Therefore, the protection scope of the present invention will be limited only by the appended claims, and should be construed as including all such changes, modifications or adjustments.

As described above, according to the present invention, when the interlocking work between the dedicated line management system and the DCS management system, the interworking request work is classified into four types, and the work processing procedure is defined accordingly, so that the user's requirements can be corrected or By accommodating various modification requirements in various fields such as necessary modification work, and designating the termination work after the final completion, it greatly simplifies the complexity due to the correction work on the termination work and improves the reliability of the dedicated communication network configuration. It can increase the efficiency of network management work.
