Guide to Edit Rejection Rejection in N-ISDN Switch

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

2 to 4 are flowcharts illustrating one embodiment of an edited call rejection guidance method according to the present invention.

The present invention is audible to the basic matching subscribers, primary group matching subscribers, basic access multiple subscribers, subscribers satisfying the N-ISDN user-network access signaling method in the exchange for narrowband integrated information communication network (hereinafter referred to as N-ISDN). And an edit rejection guide method in an N-ISDN switch configured to provide an edit rejection service in a visual manner.

Until now, the Public Switched Telephone Network (PSTN) has provided an edit-type rejection service using an analog connection for telephone subscribers.

However, in the public switched telephone network (PSTN), the signal transmission channel between the subscriber and the network is not provided separately, and only a limited service can be provided by the audible sound through the information transmission channel. The public switched telephone network (PSTN) and the N-ISDN are subscribers. There was a problem in that N-ISDN could not be applied due to different connection specifications between the exchange and the exchange period.

In addition, since the service is provided to subscribers using only audible sound, a new technology that can provide services to all N-ISDN access terminals such as telephone and data is not possible because the data cannot be provided to data mode terminals.

Therefore, the present invention provides a service success message by using the announcement announcement and LCD (Liquid Crystal Display) of the subscriber terminal to the calling subscriber who requested the call without directly answering the call requested by the subscriber. It is an object of the present invention to provide an editable rejection notification method in an N-ISDN exchange that enables a subscriber to take an active action by using an LCD of a terminal when a rejection service fails.

In order to achieve the above object, the present invention provides a plurality of access switching subsystems (ASS) for accommodating subscriber lines and trunk lines, an interconnection network subsystem (INS) connected to the plurality of ASSs, and a central control connected to the INS. In the editable call rejection guidance method applied to an electronic switch having a sub system), receiving a setup message from a subscriber and receiving an information message from the subscriber to translate the service code. step; A second step of determining whether to activate the service according to the category of the subscriber and the rejection time information when the translation result is the edited rejection service registration request; A third step of performing an edited call rejection guide service for the call received by the subscriber; A fourth step of receiving an information message, which is a service request code, from the subscriber and translating the service code upon receiving a call setup message; A fifth step of examining a category of a subscriber when the translation result is an edit rejection request; A sixth step of notifying the subscriber that cancellation is not possible if the service is not activated after performing the fifth step and releasing the call; And performing a cancellation request from the subscriber in the service activation state after performing the fifth step, deactivating the edited rejection service state of the subscriber, informing the subscriber that the service has been canceled, and then releasing the call. Characterized in that.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, briefly describing the present invention, the editable rejection service is unnecessary by providing intelligent information for notifying the calling subscriber requesting a call access to the subscriber who is connected to the N-ISDN and the time when the incoming call is being rejected. It provides convenience to users by preventing call retries, and it is a service that can reduce the load on the system by improving the call completion rate on the exchange side.

When the N-ISDN exchange and the terminal device for the edit rejection service are connected, all procedures of the N-ISDN terminal are the same as those of setting a general call and do not use additional messages or information elements. It can be used without addition and can be easily applied to all exchanges using N-ISDN subscriber-network access standard of international standard.

In addition, the service provides a visual method by providing the indication information using the N-ISDN subscriber-network signaling method using the D channel as well as the existing audible sound when registering, confirming, canceling the service and calling a subscriber to the service. It can also deliver the necessary information to the calling subscriber.

1 is a schematic structure of an all-electronic exchanger which is a distributed control system to which the present invention is applied.

As shown in the figure, the electronic switch system includes a plurality of ASS (Access Switching Subsystem) for accommodating 4096 subscriber lines and 1024 trunk lines, an Interconnection Network Subsystem (INS) connected to the ASS, and a CCS connected to the INS. It consists of three bush steams from the Central Control Subsystem.

The ASS is classified into ASS_S (Subscriber), ASS_I (ISDN Subscriber), ASS_T (Trunk), and ASS_7 (No. 7 Signaling System) according to the function. In ASS_S, the Access Switching Processor (ASP) performs call processing for ISDN subscribers accommodated in the exchange, ASS_T performs inter-station circuit call handling with ASP, and ASS_7 performs ASP and SMHP (Signaling Message Handling). The processor performs the functions of the message transfer part (MTP) and the signaling connection control part (SCCP) of the NO.7 signaling method.

In INS, Number Translation Processor (NTP) and Interconnection Network Processor (INP) perform the number translation function, routing control function, and space division switch control function, which are commonly required in each ASS. CCS operation and maintenance The function is performed.

In this way, each subsystem is connected to the INS through LDL (Local Data Link) to form an interprocess communication system.

2 to 4 are flowcharts illustrating an embodiment of a method for guiding rejection of edits according to the present invention.

2 is a process flow diagram in which an electronic switchboard receives a service registration request from a subscriber and activates a service. The processing software is mounted in ASS_I, which is an N-ISDN subscriber control module. Perform.

First, when receiving a SETUP message from the subscriber (201), the call acceptance process to send a setup response (SETUP ACK) message (202), and receives an information (INFORMATION) message from the subscriber (203), service Translate the code (204).

When entering the service code, the subscriber must first enter the supplementary service digit *, which indicates separation and registration from the general call, followed by a two-digit service code.

If the translation result is an edited rejection registration request, the subscriber's category is examined (205), and if the subscriber is not allowed to register, the user is notified that the registration is not possible using the DISCONNECT message. (210), and releases the call according to the general call release procedure (211), in the case of the service registration request from the allowed subscribers using the additional information (INFORMATION) message to announce the service time of the call reject time information and Received by the LCD of the calling subscriber terminal device (206). The service time uses two digits for the month, day, hour, and minute information, respectively, and includes * at the end of the information.

When the received time information is analyzed (207), and the value is abnormal (when the information of the month is not 1 to 12, the information of the day is not 1 to 31 (28), or the time information is not 0 to 23 , If the information of the minute is not 0 to 59) (208), and notifies the requesting subscriber through the announcement and the display device of the terminal using a DISCONNECT message (210). Release the call using the ISDN subscriber-network signaling procedure (211).

If the subscriber wants to use the month and day information as the current time, the input of the month and day information can be omitted.If the subscriber registers the month, day, hour, minute, etc. at the exchange, the registered date and The service starts from time.

On the other hand, if the received time information is valid (208), the registration time is stored and the subscriber's edited rejection service is activated (209), the broadcast announcement that the service is registered by using the DISCONNECT message to the subscriber And notify through the display device of the terminal (210) and release the call using the N-ISDN subscriber-network signaling procedure (211).

3A to 3B are flowcharts of a request for an incoming call to a subscriber whose editable rejection service is activated.

First, FIG. 3a is a flow chart of the originating exchange. When a call establishment request is received (301), if the subscriber who attempted the call is a subscriber belonging to the same N-ISDN exchange (if it is a local call), the call is requested to the called party. In step 302, the internal message is received and the incoming call rejection service time information is received (303).

When the originating processing unit receives the editable rejection service notification, the call processing unit notifies the calling party through the display device of the announcement and the terminal through the editable announcement device (304), and the called rejection service time information received from the called party. The incoming rejection service time information is transmitted to the indication information element of the DISCONNECT message according to the ISDN user-network layer 3 (305).

Therefore, the calling party subscriber can know the information of incoming call rejection and edited call rejection time through the audible sound and the display device on the terminal. Upon release, the subscriber station and exchange release the call according to the N-ISDN subscriber-network release procedure (306).

As an example of the announcement broadcast information to the calling subscriber, the number you have dialed now cannot be called by the circumstances of the subscriber, so please call again after 00 00 00 00,

As an example of the information displayed on the terminal subscriber's display device, Called Do Not Disterb (M: 00 D: 00 H: 00 M: 00) (edited rejection) may be mentioned.

3b is a flow chart of a called party subscriber side in which an editable rejection service is activated, and when the calling exchange requests a called party to the called party (302) and an incoming call is requested (307), the edited rejection service is performed. Check if is activated (308).

If the edited rejection service is not activated (309), normal call processing is performed (310), and if activated (309), the edited rejection service is performed.

As a result, it is checked whether the calling subscriber and the called subscriber are subscribers connected to the same exchange (311), and when connected to the same exchange, the internal message in the exchange is used to obtain the information of incoming and outgoing incoming calls. 312, the caller is notified through the announcement and the display device of the terminal (313), and the incoming call is released (318).

If the calling subscriber is a different exchange from the called subscriber, that is, a relay call, it cannot inform the calling party of the rejection of the incoming call because of signaling limitations. In this case, the call is informed of the editable announcement through the information transmission path (314), and for this purpose, a virtual response message is notified to the calling party (315), thereby connecting the information transmitting channel of the calling party. When receiving the release message from the calling party during the transmission of the rejection of the edit type, the announcement of the announcement is cut (317), and the incoming call is released (318).

4 is a flowchart of an operation process in which an electronic switchboard receives a service cancellation request from a subscriber and cancels the service.

Receiving a SETUP message from the subscriber (401), it is easy to process and send a response (SETUP ACK) message (402), and receives an information (INFORMATION) message of the service request code from the subscriber (403), The service code is translated (404).

When transmitting a service code, the subscriber must first enter @ #, a special digit indicating the purpose of the service and the cancellation of service, and then enter the two-digit service code. The service code is the same as in the registration request.

If the translation result is an edit rejection request, the subscriber's category is examined. If the service is not activated, the subscriber cannot be canceled using the DISCONNECT message (406). Release the call according to (408).

If the cancellation request from the subscriber in the service activation state disables the subscriber's edited rejection service status (405), and informs the subscriber that the service has been canceled using the DISCONNECT message (407), the terminal Display on the display device, and release the call using the N-ISDN (408).

Therefore, if the subscriber connected to N-ISDN exchange registers his / her incoming call rejection time to the exchange according to the simple registration procedure through the terminal equipment, the exchange is not receiving the incoming call and the rejection time of the called party for all incoming calls. This service can be provided to inform the calling party through the announcement and the display device of the terminal.

Accordingly, as described above, according to the present invention, the edit rejection function for the N-ISDN subscriber is applied to all N-ISDN exchangers using N-ISDN subscriber-network signaling of the international standard standard (CCITT). N-ISDN terminal can be provided with the edit rejection service without adding the existing function, and if the subscriber registers the edit rejection service with the N-ISDN exchange, it can be applied to all incoming calls for the registered time. There is an effect that can provide an additional communication service to notify the subscriber by using the announcement and the LCD of the terminal to the calling subscriber.
