The present invention relates to a subscriber special service out of service guidance and call rejection recording guide service method provided in an electronic switch.

In the conventional exchange, the missed guidance service function is provided, but the present invention provides not only the missed guidance but also the call rejection guide service, and not only the basic fixed recording guide indicating that the called party is missed or the call rejection, but also the voice editing. And inserting the time information desired by the subscriber into a predetermined message type using a synthesis method, and providing an editable recording guide that informs the user of a recording guide of when he is absent or a recording of call rejection until. The purpose was to provide a recording guidance service method.

The fixed announcement service is started when a subscriber who has registered a fixed missed call or fixed call rejection guide service by a telephone company operator dials a code requesting the start of the fixed missed call guide or fixed call rejection guide service. If the time is not specified and the time is not specified, the service is restarted from the time when the service start request is made, and the calling party calling the subscriber is connected to a recording guide indicating that the called party is absent or rejected. If the subscriber who started the service dials the service cancellation code, then the recording guide service is terminated.

In addition, the editable announcement service is provided by the subscribers who registered the edited missed announcement or the edited call rejection guide service by the telephone company operator. Minutes or hours), the service is started, and the calling subscriber who has called the subscriber is informed of the recording announcement that the called subscriber is absent by the hours and hours of several months and days, or the recording announcement that the incoming call is rejected, and the subscriber who started the service is started. When the service dials the service cancellation code, the recording guide service is terminated. At the end of the service desired by the subscriber, the exchange automatically terminates the service even if the subscriber does not dial the cancellation code.

However, this recording guide service is operated at the same point of time as services such as incoming call transfer and call waiting, so that each service is provided without difficulty by setting service priorities for each service and processing accordingly in order to prevent mutual conflict. It aims to provide more diverse and convenient services to subscribers by making it possible.

Therefore, in order to achieve the above object, the present invention processes a subscriber who is registered for a missed call reception service or a call rejection service by the telephone company operator when the service start request is requested, and the service starts when the service start time is specified. And a second step of connecting the fixed or editable recording guide to the calling subscriber when calling the subscriber who initiated the missed call or the reject call after performing the first step, and after performing the first step. In this case, the service is performed by the third step of terminating the service when the subscriber requests the service cancellation or the end of the editable recording guidance service desired by the subscriber.

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

2 is a schematic overall flowchart of missed and unsubscribe announcement service processing.

A subscriber registered with the fixed missed call announcement, the fixed call rejection call announcement, the edited missed call announcement or the edited call rejection call announcement service is picked up by the telephone company operator (2-1) and hears a dial tone indicating that dialing is possible. (2-2), dialing the editable announcement service code and the end time (2-3) stores the end time and the editable announcement service start information requested by the subscriber in the database (2- 4) After the subscriber requests the service termination time waiting timer (2-5), the subscriber hears a confirmation tone (2-6).

When the fixed announcement service request code is dialed (2-7), it is checked whether the service start time is specified (2-8), and if so, the service start time waiting timer (2-9) is started (2-9). When the subscriber starts the service start time (2-11), the fixed announcement service start information is stored in the database (2-12).

If the service start time is not specified, a confirmation tone is immediately transmitted to the subscriber (2-13), and the fixed announcement service start information is stored in a database. When an incoming call is requested to a subscriber who starts recording service (2-14), the subscriber's information is examined (2-15), and if the incoming call is not possible, the call is cut (2-16). Investigate whether the incoming call rejection service is initiating (2-17), and if so, process to inform the calling subscriber of the recording announcement (2-18). (2-19)

At this time, if the edited out-of-office guide or the edit-type rejection recording guide service end waiting time out occurs (Fig. 2-20), the service is terminated by deleting the information stored in the database (Fig. 2-20). 2-21). If the subscriber requests to cancel the missed or unsubscribe recording guidance service (2-22), the subscriber checks whether the service start waiting or end waiting timer (Timer) is in operation (Fig. 2-23). After the cancellation (2-24), the information stored in the database is deleted (Fig. 2-25), and the subscriber is notified (Fig. 2-26) to terminate the service.

Detailed processing is described in FIG. 3 and FIG.

When the subscriber picks up the handset (3-1) at rest and hears a dial tone (3-5) indicating that he can turn the dial (3-5), turning the first digit (3-6), the dial tone is cut off (3-7), After receiving the remaining digits from (3-8), it analyzes and checks if the service is registered by the operator (3-9) if it is required to start a fixed missed call announcement or fixed call rejection recording guide service (3-9). 10), if not registered, an error beep (3-23), indicating that the service failed to start, and when the subscriber puts down the handset (3-24), cuts out the error (3-25) and uses it. The cutting process for initializing the various equipment was performed (3-26).

In addition, if a fixed missed call guide or a fixed call rejection guide service is registered by the operator, it is checked whether the service start time is specified (3-14), and if so, the service start wait timer (3-15) is operated (3-15). If not specified, the fixed announcement service start information is stored in the database (3-16).

Then a confirmation tone is heard (3-17) to inform the subscriber that the service has been initiated successfully, when the subscriber puts down the handset (3-18), the confirmation tone is cut off (3-19), Carry out a cutting process to initialize the machine (3-20). If the subscriber has designated the service start start (3-15) and the service start waiting timeout occurs due to the timer operated in (3-15) (3-2), the operator checks whether the service is registered. (3-3) If not registered, the service is terminated. If registered, the fixed announcement service start information is stored in the database (3-4).

The calling party who calls this subscriber then hears a recording announcement that the calling party is either "out of office" or "unsubscribed." If the result of analyzing the digits received from the subscriber is a request for starting the editable missed call announcement or the call rejection call announcement service (3-11), it is checked whether the service is registered by the operator (3-13). If it is not registered, it will sound an error to indicate that the service has failed, and perform the truncation process between (2-23) and (3-26), and if it is registered, it will wait for the end time of service specified by the subscriber. Running a timer (3-12), storing editable announcement service initiation information in the database (3-22), giving a confirmation tone to indicate that the service has been started successfully and allowing the subscriber to disconnect (3-17) ) To (3-20). The calling party who calls this subscriber then hears a recording announcement that the called party is either "not present" or "unrestricted". In addition, if it is not a request for starting a fixed or editable recording announcement service that analyzes the digit received from the subscriber, the service is processed (3-12).

FIG. 4 is a flow chart showing the recording guidance to the calling subscriber calling the subscriber who initiated the fixed recording guide or the editable recording guide service in FIG. When the calling subscriber calls the subscriber who started the recording guidance service and the incoming call request is received (4-1), the incoming subscriber information is examined (4-2). The processing is performed (4-3), and if possible, the caller checks whether the fixed missed call announcement or the fixed call rejection recording service is started (4-4). Investigate whether the call is initiated (4-4), and if the service is being started, connect a switch between the calling subscriber line and the fixed call announcement device (4-5) to notify the calling subscriber that the called subscriber is absent or not being called. (4-6), when the calling subscriber puts down the handset (4-7), cuts the announcement (4-8), cuts off the switch between the calling subscriber and the stationary announcement ( 4-9), a cutting process for initializing various used equipment is performed (4-10).

Also, if the fixed announcement service is not started, investigate whether the edited missed call announcement or the edited call rejection announcement service is started (4-11), and if the service starts, switch between the calling subscriber line and the editable announcement device. Connect (4-13), and the caller is informed of the recording announcement to indicate when the called party is absent or rejected (4-14), and when the caller puts down the handset (4-15), the call is cut. (4-16), cut the switch between the calling subscriber and the editable recording guidance device (4-16), and perform a cutting process for initializing various used equipment (4-18). If the editable recording guide service is also not started, it checks whether another service that can be provided at that point is registered and processes the corresponding service (4-12).
