Referring to the operation of the additional service system configured as described above, when the subscriber requests additional services, the exchange distinguishes the additional services requested by the subscriber and then provides the service resources 11, 12, 13) Replace the relay line.

At this time, the service resources (11, 12, 13) of the additional service equipment is operated under the assumption that all channels of the relay line inputted to it are requests of subscribers requesting their resources, that is, one additional service device In the case of providing various kinds of services, the exchange interworking with the supplementary service device recognizes the subscriber's requirements and adds the supplementary service to the corresponding service resource (11, 12, 13) according to the requested supplementary service type. Since the service needs to be exchanged, it is possible only by adding a new function to the existing exchange.

Since the exchange must distinguish the type of service and provide it to the service resources (11, 12, 13), the function additional burden of the exchange occurs and whenever the change of the additional service occurs, the function change of the exchange occurs. do.

For example, when a subscriber's request for a FAX service increases in an additional service device that simultaneously provides a VMS and a FAX service, the FAX service resource 13 needs to be increased, and at the same time, a function modification is required at the corresponding exchange. .

As such, in the related art, in addition to the addition of service resources continuously required due to an increase in various service demands of subscribers, there is an inconvenience of not only adding the corresponding service resources to the new service request, but also requiring the corresponding function to change the function. .

In order to solve the inconvenience as described above, the additional service resource sharing system and method of the switch according to the present invention relates to the sharing of the additional service resources in the system for providing the additional service to switch the relay line channel on the back board PSTN An object of the present invention is to share a service resource of an additional service device that interoperates with.

In other words, when the present invention provides various additional services such as VMS, ARS, and FAX services, the present invention is more suitable for the additional service system interworking with the exchange in the PSTN while more effectively sharing the service resources and the method of distinguishing the additional services. In this case, when the addition of service resources is required, it is possible to simply add the service resources in the device, and even if a new service is created, only new service resources are added so that the service is continuously demanded due to the increase of various service requests of subscribers. It aims to smoothly respond to the addition of resources and new service requirements.

2 is a block diagram illustrating an additional service resource sharing system of an exchange according to an embodiment of the present invention, and FIG. 3 is a flowchart illustrating an additional service resource sharing method of an exchange according to an embodiment of the present invention.

As shown in FIG. 2, a configuration of an additional service resource sharing system of an exchange according to an embodiment of the present invention includes a plurality of VMS service resources 21, a plurality of ARS service resources 22, and a plurality of FAX service resources. 23, the back board 24, and the central control part 25 are comprised.

The VMS service resource 21, the ARS service resource 22, and the FAX service resource 23 receive the subscriber's requirements from the corresponding exchange through the relay line, and relay the line registration line to read the subscriber's request by signaling the relay line matching line. 31 and a switching command from the central control unit 25, connected to the relay line bus of the back board 24, and applying a relay line channel of the subscriber request to the central control unit 25 through the connected relay line bus. It includes a switch module 32 and a service providing module 33 for receiving an additional service by receiving a service providing command or a response command from the central control unit 25.

The back board 24 includes a signal bus and a trunk line bus and interfaces information between the service resources 21, 22, and 23 and the central control unit 25 through the signal bus and the trunk line bus.

The central control unit 25 receives the subscriber request information read from the service resources 21, 22, and 23 to discriminate whether the corresponding service request is a valid subscriber, classify the type of the service request, and classify the corresponding service request. Instructs the service resources 21, 22, and 23 to provide a service according to whether the service request corresponding to the service resources 21, 22, and 23 for which the service request is authorized is requested, or the relay line bus of the back board 24. Command to switch to receive the relay channel to respond to the service request.

The additional service resource sharing system of the exchange according to the embodiment of the present invention performs the following operation as shown in the flowchart of FIG. 3.

If the subscriber requests any service, the exchange exchanges the service request call, where the relay line to which the service request call is authorized is transferred to any service resource (21, 22) through any relay line that is not in service by the exchange. , 23).

Then, the service resources 21, 22, and 23 perform relay line matching line signaling through the relay line matching module 31 included in the service resource 21, 22, 23, and read the service request of the subscriber, and then read the corresponding information on the back board ( 24 is applied to the central control unit 25 via the signal bus.

Accordingly, the central control unit 25 checks whether the service request information of the subscriber is authorized through the signal bus of the back board 24 (step S1), and checks the subscriber through the subscriber telephone number of the authorized subscriber. Distinguish whether the corresponding service request is a valid subscriber (step S2).

If the subscriber is not a valid subscriber who can request service, it is checked whether the service request information of the subscriber is authorized through the signal bus of the back board 24 in the first step S1, and the corresponding effective subscriber. If so, the central control unit 25 classifies the type of service requested by the subscriber (step S3). The central control unit 25 checks whether the type of the checked service request requires a service corresponding to a service resource authorized for the service request call among the service resources 21, 22, and 23 (step S4). ).

Accordingly, if the type of service requested by the subscriber is a service that does not correspond to the service resources 21, 22, and 23 authorized for the service request, the central control unit 25 may not perform the requested service. A switching command is applied to the switch module 32 provided in the service resources 21, 22, and 23 so as to connect the relay line channel of the subscriber who requested the service to the relay line bus on the back board 24 (step S5). . Then, the relay line channel of the subscriber requesting the service is carried on the relay line bus of the back board 24 (step S6), and the central control unit 25 provides a service resource for providing the service requested by the subscriber. (21, 22, 23) is allowed to receive the corresponding relay line channel through the switch module 32 (step S6) and a response command is issued to respond to the service request (step S7).

If the type of service requested by the subscriber is a service corresponding to the service resources 21, 22, and 23 authorized for the service request, the central control unit 25 corresponds to the service resources 21, 22, and 23. Instructing the service provider to provide the additional service (step S8).

For example, when any service subscriber requests a FAX service, the exchange exchanges the subscriber's requirements on the relay line, where the requested service request call is performed on the relay line connected to the VMS service resource 21. If authorized through the VMS service resources 21 performs the relay line signaling through the relay line matching module 31 and applies the corresponding result to the central control unit 25.

Accordingly, the central control unit 25 determines whether the subscriber is valid, and instructs the service resources 21, 22, and 23 to provide the requested service if the subscriber is valid. Is FAX, the VMS service resource 21 is unable to provide a service.

In this case, the central control unit 25 commands the relay line bus of the back board 24 to switch the corresponding trunk line channel through the switch module 32 of the VMS service resource 21. That is, the service request relay line channel connected to the service resources (21, 22, 23) according to the present invention in the exchange is carried on the corresponding relay line bus, the central control unit 25 is a FAX service resource ( 23) commands the corresponding trunk line channel from the corresponding trunk line bus to respond to the service requested by the subscriber. Then, the FAX service resource 23 which received the command provides the service requested by the subscriber.

On the other hand, when the VMS service is requested through the relay line connected to the FAX service resource 23, the central control unit 25 instructs the VMS service resource 21 to switch over the corresponding trunk line bus to provide the service. do.

The present invention facilitates the addition of service resources 21, 22, and 23 that are continuously required by the increase of various service requests of subscribers, and the corresponding service resources 21, 22, and 23. In the case where addition is required, in the related art, as well as the addition of the service resource, a function conversion is required according to the addition in the exchange. However, the present invention has been made possible by simply adding the service resource in the device, even when a new service is created. Just add it.

As described above, when a service that does not correspond to a service resource is required by the present invention, the service resource can be switched to a service resource capable of the corresponding service through a relay line bus, thereby sharing the service resource of additional service equipment linked to the PSTN. It is possible to simply add a service resource in the device at the request of adding a new service and to add a new service resource only when creating a new service.
