The present invention relates to a caller indication service method using a hierarchical structure. More particularly, the present invention relates to a hierarchical management of exchange system, module, and port states starting from the line information where the subscriber is located to the subscriber's exchange port. The present invention relates to a caller ID service method using a structure.

With the rapid development of the information and communication field, the physical media of subscriber lines are changing from copper lines to optical lines, from telephone-oriented services to multimedia and value-added services.

With the explosive growth of PC communication and Internet usage, efficient provision and operation management of Internet data services is a measure of the competitiveness of telecommunication operators. However, the infrastructure and services that provide Internet data services are becoming more complex and diversified, making it more difficult to provide and manage the services. The complexity of various facilities and services in the field of ADSL, Internet and data communication is expected to continue to increase, and there is a need for a systematic and efficient service opening platform that efficiently handles the above services.

On the other hand, there are various types of exchanges (more than 10 models) and lines in a conventional telecommunications provider. In other words, the old and new exchanges are mixed, and the line is composed of a complicated structure of optical lines and copper lines. When a customer service opening request is required, the line, MDF, and exchange port suitable for subscriber service are appropriately selected, and a work instruction is given to a worker. It is one of the basic tasks from the point of view of the telcos that provide the service to perform and complete the work, and to open the service until the customer's desired date.                         

South Korea ranks first in the world for Internet data services. There are 35 million phone lines, 3.5 million Internet data lines, and customers are close to the telephone office, which makes it easy to accommodate Internet data services. However, the complexity of facilities and services in accommodating Internet data services continues to increase, and efficient management and immediate provision of services can be a measure of a company's competitiveness.

The caller identification service is a service which a service user can selectively call by displaying the caller's telephone number on the telephone or terminal of the called party before the call starts. The caller information display service was initially launched as a malicious tracking service, and is now a popularized service open to all general customers who want to receive the service.

In providing the service, if all modules are provided to provide service, it is not necessary to determine whether the service can be provided, but at present, it is not possible to replace the subscriber board for the demand of an unspecified service subscriber. There is this. Therefore, it is inevitable to increase or reduce the available modules according to the customer's acceptance situation, and the serviceable modules can be said to be only some modules compared to the whole modules.

For example, if you look at the facilities inside the Korea Telecommunication Corporation, it is not so simple. That is, in the case of the caller identification service, it cannot be said that the service can be naturally provided to all customers. Because there are various exchangers (TDX-1A, TDX-1B, TDX-10, TDX-100, AXE-10, 5ESS, No.1A, S1240, M10CN, etc.) Some exchanges are serviceable, but some are not. Among the exchanges that can be serviced, there are also exchanges that allow only some modules.

In addition, if the subscriber's premises are in the same facility and the module of the switch used by the subscriber is not available for service, the existing jumper should be disconnected and a rejumper should be performed to an adjacent module that can serve. In addition, the subscriber using the optical facility does not provide services in units of ports, but uses telephone service in units of specific modules, so that the service of the corresponding module is impossible or the service of the exchange is available. If the module is not possible, eventually the caller ID service will be disabled.

When a contract is signed to provide Caller-ID services with a specific customer, if the work is handled manually without any knowledge of the system and facilities, the telephone district immediately provides hundreds of new Caller-ID new and change orders per day. It is impossible to do.

This is because Caller-ID service is one of the services that is difficult for the operators working in the unit work in the telephone station where jumper work is frequently performed because there are not many exchanges, modules and ports available. However, because the forecasting of service needs is unspecified, there is no need for a large number of facilities in advance, and in fact, in recent trends where a small number of subscribers use a limited time for various services, and another service is added, this trend It can be said that it is getting worse.

For example, in the case of Korea Telecommunication Corporation, a system for issuing services (ICIS) and a system for managing and opening facilities (TIMS) are operated separately. have. The service issuing system may initially identify the customer with facility information and notify the customer in advance depending on the availability of the facility, but due to the complexity of the facility information, After the service is issued, there is a problem that the opening processing system should obtain a command to determine the state of the facility.

An object of the present invention for solving the problems of the prior art as described above is to provide a caller-ID information and whether the service of the line and the exchange system can be provided in order to handle the fluctuation of the new and existing subscribers that occur in large quantities To provide a method for providing a caller indication service that manages up to a port unit.

In order to achieve the above object, according to the present invention, in the method of providing a Caller-ID service using a hierarchical structure, a caller-ID service request checks whether the exchange of the corresponding telephone number can provide the service. Opening the Caller-ID line if the entire module to which the requested line belongs is possible or the module currently being used is possible; If the current module does not support the Caller-ID service, checking whether there is an available port in the module, and if the available port exists, selecting a new exchange port for the CID by the subscriber; If the external port of the newly selected subscriber is the copper line, the internal line operation is performed to hold the caller-ID service line, and if the external line is the optical line, the corresponding external line and the internal line are newly caught at the same time. Catching with an ID service line; If there are no ports available in all modules, and all subscribers occupy ports, there is a step of crossing the ports of users who need Caller-ID service with those of users who do not need Caller-ID service. It provides a caller-ID service provision method

First, the Caller-ID new and volatility orders required by the sales system can be used and disabled by system, module and port status by exchange characteristics, starting from the line information of the location where the subscriber is located, to the subscriber's exchange port. define. The details are as follows.

If the service is available immediately by recording and managing the information for each line characteristic, it is divided into the case where the jumper work inside the telephone station should be performed and the incoming line work outside the telephone station should be performed.

In addition, it provides a method of handling tasks related to service provision, and separately defines and manages Caller-ID unique port, general telephone and Caller_ID public port of the port, so that the facility can be operated smoothly and immediate service can be provided. Implement

In order to provide a corresponding service, in case of an exchange capable of serving a port of an exchange used by a subscriber, only a corresponding exchange command setting operation needs to be performed at the exchange. To this end, connection information is required for which exchange the customer belongs.

[Table 1] below is a table showing whether the service is available by switch type, and [Table 2] is a table illustrating the number of subscribers by load group and load group by switch type.

order Exchanger Load group unit Subscribers by load group One No.1A Concentrator 32, 64 2 5ESS Line unit 256, 384, 512 3 AXE-10 Line switch module 128 4 TDX-1A, 1B Subscriber Line Processor 1024 5 TDX-10 Access switching processor 4096 6 S1240 Network address 128 7 TDX-10A Subscriber Line Processor 8192 8 TDX-100 Subscriber Line Processor 32768

order Exchanger Available by module Exchange All module services available One TDX-1B Yes No 2 TDX-10 Yes No 3 TDX-10A Yes No 4 TDX-100 Yes No 5 5ESS, 5ESS-2000 Yes No 6 AX-10, Ver34 Yes Yes 7 TDX-1A No No 8 No.1A No No 9 S1240 No No 10 AX-10, Ver23 NO No

In the above [Table 1], the customer using the 7-10 exchanger is unable to provide the service. Thus, in order to provide a service, a change must be made to an exchange capable of providing a service, and for this purpose, the telephone number of the corresponding customer must be changed. AXE-10 and Ver34 are the only exchanges that can be checked even if only the exchanges are available. The exchanges of 1 to 5 can be serviced by modules. That is, it is possible to find out which service is available by using which module of the exchange. If the exchange is available for each module even if the service can be provided, if the ports in the module are all in use, the service is impossible. Therefore, the change should be made to a module capable of other services.

The exchange has a different number of subscribers for each module. Looking at the above [Table 2] showing the load group unit of the exchange and the number of demand subscribers per module of the exchange, it can be seen that the capacity of the subscriber increases as the new exchange.

According to the present invention, the facility information of the MDF and the exchange of the ISP (InSide Plant) side and the facility information of the OSP (OutSide Plant) should be used.

1 is a view showing a work flow related to service opening to which the present invention is applied, and the work related to service opening is divided into a sales system and a configuration management system.

First, when a customer requests a service (101), the sales system accepts the service request (102) and issues an order associated therewith (103). The issued command is sent to the configuration management system to obtain the issued command (104), select the OSP and IPS (105, 106), and perform hypothesis and MDF jumper operations (107) to process the exchange command. (108). Subsequently, after the command input opening confirmation 109 process of the exchange is completed, the completion process 110 is performed to make the service available to the subscriber 1110, and charging is then entered.

FIG. 2 is a diagram illustrating facility and subscriber information required for providing a caller-ID service to which the present invention is applied. The facility and subscriber information includes subscriber information, exchange system information, exchange module information, exchange port information, and external copper line. It is divided into information and external light.

The subscriber information is mapped to the subscriber's telephone number, the external line and internal line exchange facility information used, and the data column includes the telephone number, the copper line, the optical line, the exchange port, the service use type, and the telephone number use state. Described.

The exchange system information includes the telephone station belonging to the exchange, its corresponding station number, and whether or not the caller-ID (shortened CID) can be used and management information, and the data column includes the telephone company code, the exchange ID, the start station number, the end station number, and the Caller-ID. The presence or absence is described.

The module information of the exchange includes a module inside the exchange and management information on whether Caller-ID is available for the corresponding module, and the data column describes the classification of the mother station, the exchange module ID and caller-ID availability.

The port information of the exchange includes the management status of the port information inside the exchange and the management of caller-ID availability, and the data column includes the mother station classification, the exchange port ID, the location of the MDF cluster, the presence or absence of caller-ID, and the usage status. And telephone numbers.

The external copper line information includes contents such as a use state and a telephone number, and an external copper line ID, a state of use and a telephone number are described in the data column.

The external optical path information contains contents such as a use state and a telephone number, and the external column ID, a usage state and a telephone number are described in the data column.

3 is a diagram illustrating a hierarchical structure, connection, and relationship of an ISP and an OSP according to an embodiment of the present invention. The exchange is divided into three tiers, and the OSP is divided into a copper track facility and an optical fiber facility. It is possible. The contents of the information of each structure, i.e., the exchange system, the module, the port, the copper line facility and the optical fiber line facility, are described as simple variables in FIG. 3, which is not an essential element of the present invention, and thus description thereof will be omitted. .

It is proposed in the present invention to divide the exchanger into exchange systems, modules and ports as shown in Figure 3, and to manage them.                     

Of course, there are switching devices, transmission devices, and data devices inside the ISP, but in the case of Caller-ID, a service using a switching device, and the structure of the switching device includes a switching system, a module, and a port.

4 is a view illustrating a state of a caller-ID according to an embodiment of the present invention. When a service is available to the switching device and when it is impossible, whether the caller-ID module can be used as a caller-ID dedicated module if possible. It is shown.

As shown in FIG. 4, 'Y' is a case where Caller-ID is available, and indicates that the caller-ID subscriber can use it. 'N' indicates that Caller-ID is not available, and 'A' indicates when all modules can support Caller-ID.

5 is a flowchart illustrating a hierarchical business process for providing a caller-ID service according to an embodiment of the present invention.

The module consists of three layers and consists of the system of the exchange, the available state of the module, and the process of the availability of the port.

First, in step S401, when the Caller-ID service is requested, in step S402, the business system issues a command, and the configuration management system obtains the command. Subsequently, in step S403, a check operation is performed to determine whether the exchange of the corresponding telephone number can provide the service, and in step S404, it is determined whether or not the entire support is possible.

If the whole support is possible as a result of the determination in step S404, the exchange command ends in step S405.

If the result of the determination in step S404 is that the whole is not supported, the service is not supported in step S406, and thus ends.

As a result of the determination in step S404, if support by module is possible, it is determined in step S407 whether the current module is usable.

As a result of the determination in step S407, if it is available, in step S408, the exchange command is input and then ends.

On the other hand, if it is impossible to use the result of the determination in step S407, it is determined in step S409 whether there is a usable module.

As a result of the determination in step S409, if an available module exists, a process of finding an empty port of the available module is performed in step S410, and in step S411, it is determined whether there is an empty port.

As a result of the determination in step S411, if there is an empty port, it is determined in step S412 whether the customer's line is a copper line, and if there is no empty port, the flow advances to step S417.

If the customer's line is the copper line as a result of the determination in step S412, the internal MDF jumper operation is performed in step S413. In step S414, the existing port is canceled, and a novelty command is input to the new port. Quit.

If the customer's track is not the copper track as a result of the determination in step S412, after selecting a new external copper track in step S415, in step S416, a field worker is dispatched to perform the incoming line operation and then the step Proceed to step S413.

On the other hand, if there is no module available as a result of the determination in step S409, it is determined in step S417 whether the current module is the last module.

As a result of the determination in step S417, if it is the last module, since service is not available, the process is terminated. If not, the process of searching for an available module is performed in step S418. Then, in step S419, it is determined whether there exists a port which occupies a port and does not use a service.

As a result of the determination in step S419, if there is no present, the process proceeds to step S418. If there is, in step S420, it is checked whether the customer's track is a copper track.

As a result of the determination in step S420, if it is the copper line, the cross MDF jumper operation is performed in step S423, the port in use is canceled and a new operation is performed in step S424, and then, in step S425, the caller-ID subscriber Terminate and perform new work and terminate.

As a result of the determination in step S420, if it is not the copper line, in step S421 a new external copper line is newly selected, and in step S422, a field worker is dispatched to carry out the incoming line work, and then the flow advances to step S423.

On the other hand, if there is no free port as a result of the determination in step S411, the flow proceeds to step S417.

The business algorithm shown in FIG. 5 can be summarized as follows.

First, when the caller-ID service is requested, the sales system issues a command, and after the configuration management system obtains the command, it checks whether the exchange of the corresponding telephone number can provide the service. It can be said. Of course, even if the subscriber requests Caller-ID service at the same time as the new phone subscription, whether or not the service can be provided in step 1 is immediately determined whether the sales system designates the corresponding telephone number or not.

On the other hand, the whole module may not be supported during the service request, and may be supported on a module basis. In this case, it is necessary to determine whether the module can be supported. This may be referred to as a layer 2 operation. In this case, there may be a case of an existing subscriber and a new subscriber. In the case of an existing subscriber, the port currently used may be used immediately. However, if a new subscriber or a module of the subscriber is not available, the available module must be found.

Of course, it is possible to check whether the service can be provided in units of ports, but in the case of a port, it is unnecessary work because a port of 200,000 to 1 million subscribers must be checked in a telecommunications company. In other words, finding a serviceable module is a two-step task.

Step 3 is to check whether there is an available port inside the module. Once the available ports have been selected, step 3 is terminated and the rail work phase for service provision is completed. If the subscriber selects a new exchange port for the CID, that is, an internal line port, it is necessary to check whether the corresponding external line is a copper line or an optical line. If it is a copper line, the existing distribution line 0 and extension 0 are disconnected by MDF (Main Distribution Frame) work inside the telephone station and connected to the extension line 0 and extension 1. Station 0 performs a revocation RC (Rescent Change: command input and result analysis work for an exchange specific port), and station 1 inputs a Caller-ID command simultaneously with the new RC.

However, if the line is a light line, the module cannot be found and a new module has been found. The difference between subscribers who use copper lines and subscribers who use optical lines is that subscribers who use copper lines can work only with the jumper of MDF in the telephone company. In other words, you only need to perform internal track work. In case of the subscriber who used the optical fiber, the optical cable should be removed, the other external copper line should be selected, and reconnected with the pre-selected exchange port. In other words, the external track and the internal track work take place simultaneously.

Existing optical ports that have been connected from the optical line to the internal line should be terminated RC and new RC work should be performed on the new ports.

Secondly, all ports in the module may be unavailable. In this case, the jumper jumps to the second step to go to a new module selection work step.

Third, there are no ports available on all modules, and all subscribers may occupy ports.

FIG. 6 is a diagram illustrating processing of a CID service when there is no port available in all modules.

In this case, there may be subscribers who occupy the port but do not use the service. As shown in FIG. 6, although there is a d3-e3 connected user and a d1-e1 connected user, and the d3-e3 connected user does not support CID service, if CID service support is requested, CID service support is possible. By crossing the lines with the d1-e1 connected users who do not use them, all users can be satisfied. By doing this, you can make full use of the serviceable ports of your telephone company.

In addition, for subscribers who abolish services, not only abolish the service, but also perform the function of handing over a port to a non-serviceable general module to efficiently manage the line facilities with minimal investment.

While the invention has been described above based on the preferred embodiments thereof, these embodiments are intended to illustrate rather than limit the invention. 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 by the appended claims, and should be construed as including all such changes, modifications or adjustments.

 As described above, according to the present invention, in the case of the CID service, the structure of the switching device is divided into three levels, a switching system, a module and a port, and the CID management is automated, so that the line facilities can be efficiently managed with minimal investment. There is.
