2 is a diagram illustrating a designated time registration procedure of a digital subscriber;

3 is a flow chart of processing time notification of a digital subscriber.

According to the present invention, the subscriber announces the announcement to the subscriber at the designated time registered by the designated time notification function in the electronic N-ISDN environment and announces the announcement to the subscriber's terminal display device to inform the subscriber that the designated time is notified when the subscriber responds. The present invention relates to a digital subscriber designated time notification service processing method in an electronic integrated telecommunication network switch.

The designated time notification function provided in the existing telephone network (PSDT) is a technology that is processed by an analog access method for a subscriber using a telephone. In the existing voice network, since a signal transmission channel between a subscriber and a network is not provided separately, only a service using an audible sound can be provided because a service is provided through an information transmission channel, and it is not applicable to N-ISDN. In addition, in the N-ISDN, it is possible to provide text through the display device of the terminal, but it is impossible in the PSTN, so a new technology that can accommodate all of these is required.

The present invention devised to meet the above requirements is to provide a ring to the subscriber's terminal at a desired time when using a digital subscriber service having a designated time notification service function in an electronic N-ISDN environment. When a response is made, a designated time notification function is realized by providing a designated time notification announcement broadcast using an audible sound and a visual message informing the subscriber terminal of the designated time notification, and interworking with an existing telephone network (PSTN) is also possible. The purpose of the present invention is to provide a method for processing a digital subscriber designated time notification service in an electronic general information telecommunication network switch.

In order to achieve the above object, the present invention provides a matching method applied to an electronic switch having three subsystems: an access switching subsystem (ASS), an interconnection network subsystem (INS), and a central control subsystem (CCS). A first step in which a call setup message (SETUP) requesting acceptance of a call is received by the DCC, which is a basic call processing block, and a call setup response message (SETUP ACK) is sent by the originating subscriber to lift the handset; A second step of checking a service code length when a subscriber inputs a designated time notification code and time; A third step of performing a service code translation request if the number of digits received is the number of translatable numbers after performing the second step, and waiting for the next digit to enter if the number of digits received is insufficient; A fourth step of, after performing the second step, receiving a notification of non-conformance of the service code in response to service code translation, and checking the presence or absence of a password (KEY) of the subscriber when receiving a notification indicating that the service is an additional service; A fifth step of releasing the call if the wrong number is received when there is a password after the fourth step and checking whether the range of the designated time is valid to the next step if the password is not present or the correct password is received; If the wrong time range is entered, the call is released. If the range of time designation is judged to be correct, the specified time is stored in the database, and the specified time is registered and registered in the CROS (Concurrent Real Time Operator) provided by the electronic exchange. The sixth step is made.

The present invention provides a processing technique in a network at the time of registering a designated time for requesting a subscriber service in an electronic switching N-ISDN environment, a processing method in a network when a service is started, and a cancellation, confirmation and failure of a service. It describes in detail the process of processing and describes the interworking relationship with the existing voice network, and the designated time notification function of the digital subscriber is a pure software block that is mounted on the ASS, which is a subsystem of the electronic switching system, which is a distributed control system.

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

1 is a schematic structural diagram of an electro-electric exchanger to which the present invention is applied.

The electronic switching system consists of three subsystems: the access switching subsystem (ASS), the inconconchonchon network subsystem (INS), and the central control subsystem (CCS).

The main function of ASS is call processing function, but there is one function, but it is classified as ASS-S (Subschber), ASS-T (Tmnk), ASS-No.7 Signaling System, and ASS-P (Packet) It is possible to combine these various forms.

INS is responsible for message communication between ASS or ASS and CCS. Number Translation Processor (NTP) and Interconnection Network Processor (INP) are performed for number translation, route control, and space division switch control respectively.

CCS is responsible for the overall operation and maintenance of the system, including system operation, testing and measurement, control and mass storage management, control of various I / O devices, and data channel connections to other systems.

The present invention largely consists of the registration of services and the provision of services. First, the process of registering services and processing when services are provided will be described, and then the process of canceling and confirming services will be explained. This will be explained in.

The subscriber recognizes that he / she has received all digits from the network only after entering the service code and time and finally enters the service code and time. Explain.

First, a description is given of a designated time round of a subscriber for receiving a designated time notification service.

Registration of the designated time is completed when the subscriber picks up the receiver and inputs the designated time notification code and time. If the subscriber has a password function, the password must be entered after the service code. Use '* 77' as the service code to receive only one designated time notification service, and use '* 79' for the service that is repeated every day. The use of these codes can be changed by the operator.

* 77 (* 79) + [month + day] + hour + minute *

Month and day are not necessary when using '* 79', which is a service that repeats every day. When using '* 77 *', which is a one-time service, the month and day must be entered. The date is entered.

2 is a flowchart illustrating a process of processing a subscriber's operation in a network according to the present invention.

When the originating subscriber lifts the handset, a call setup message (SETUP) requesting acceptance of the call is received by the basic call processing block DCC (20l). The DCC sends a SETUP ACK message to the subscriber to accept it (202). The subscriber then enters the specified time notification code 77 and the time starting with the special character '*'. When the DCC receives the special character '*' and requests the control to inherit the DSSC, the additional service control block, the DSSC takes charge of the control and receives the service code and time (203).

The DSSC, which is an additional service processing block, requests service code translation when the number of digits received is 204. If not, release the call. In response to service code translation, if a non-compliance notice is received in service code (206), the service is released (207). If the user is notified that the service is an additional service (207), the subscriber's password (KEY) is examined (208). When a call is received, the call is released. If no password is found or a valid password is received, the next step is to check whether the range of time is valid (Month: 01-12, Day; 01-23, Hour; 00-23, Minute; 00-59) (209). If the wrong time range is entered, the call is released. If the time range is determined to be correct, the specified time is stored in the database (210) and the specified time is registered in the CROS (Concurrent ReaI Time Operator) provided by the electronic exchange. Processing is completed and the subscriber hears a confirmation tone notifying the completion of the designated time registration and releases the call (211).

In addition, the designated time notification service shown in FIG. 3 is SSCO which is a special service processing block which recognizes this message when it sends a message (WKPToutRP) indicating that the CROS of the electronic switch is the designated time notification when the designated time registered by the subscriber is reached. In step 301, the subscriber's category is analyzed (302), and the SSCO is processed by the SSCO (303). In the case of the ISDN subscriber, when the request for processing the designated time to the DSSC in charge of service control of the ISDN subscriber (304), the DSSC directly controls the notification of the designated time. First, if the status of the subscriber is checked (305) and the call, incoming call transfer, and missed guidance service are registered, the service is unavailable or meaningless, so that the time after a predetermined time interval (wkrp_interval) is required for retrying the designated time notification. The call is released after re-registering the designated time. If the subscriber is an idle, the processing is changed according to the subscriber's response after sending a call setup message indicating the incoming call to the subscriber.

If the subscriber does not answer dmd for a predetermined time (wkp_ring_time), the subscriber registers the designated time again for retrying (206) and then releases it. When the subscriber responds, the notification of the designated time is completed by providing an announcement and a text indication to the terminal of the subscriber. The notification of the designated time is provided once more after a certain time (wkp_interval) if the service is unavailable, such as during a busy or non-answering call of the subscriber. Deliver to operational processing and complete service.

If the subscriber cancels the designated time after inputting the designated time, if the subscriber enters the intelligent time cancellation code '# 77' without inputting the registered time, the service receives it from the network and deletes the designated time of the subscriber. . If the user inputs '#' by lifting the subscriber's handset in the same way as the designated time registration, it receives DCC Guy, the basic call processing block, and requests control succession to DSSC, the additional service processing block. DSSC, which has inherited the control, receives the '# 77' and requests the number translation to NTR, the number translation processing block, and if it is informed that the specified time is canceled, the designated time cancellation request message (WKPCancelRQ) Send it. Upon receiving this, SSC0 clears the designated time of the subscriber stored in the exchange database, deletes the designated time of the subscriber stored in its own table, and sends a branch time cancellation completion message (WKPSveOK) to DSSC. The service is terminated by providing a subscriber with a confirmation sound to indicate completion.

In the case of confirmation of the designated time, confirmation of the designated time requires input of the service code '* 7l' and the time registered by the subscriber, and receives '*' from the basic call processing block, DCC, and requests control to be transferred to DSSC, an additional service processing block. do. DSSC, which has inherited control, requests number translation to NTR, which is a number translation processing block when it receives up to '71', and receives and saves the time entered by subscriber when it is informed that it is designated time confirmation service, and designates its own line number in database. The service is terminated by reading the time notification time, comparing and comparing with each other and failing.

Therefore, the effects of the present invention as described above can be implemented while minimizing the load of the ISDN environment by designing the designated time notification function under the electronic switching N-ISDN environment by utilizing the functions already implemented in the existing PSIN network. By configuring software block separate from call processing, it is easy to control call due to load sharing and role sharing with basic call processing and can provide designated time notification service in ISDN environment without changing existing call processing procedure of PSTN network. have. In addition, the ISDN network, which provides only the announcement broadcast when the service is started in the existing voice network, provides a visual indication to the subscriber terminal at the same time, thereby improving the quality of service.
