Service (Private Virtual Network Service), Personal Number Service, Televoting Service, Emergency Number Service, Voice Mail Service, Electronic Mail Service Service, Call Me Card Service, and the like.

On the other hand, an answering machine used in a normal telephone network is used to notify a caller of his or her absence by leaving a message when an individual is absent. However, the missed message delivery method has a burden that each user has an expensive answering machine. In addition, the answering machine can only provide a level of function to record the caller's voice message. When the answering machine is used in a general telephone network, there is no way to provide call forwarding to another area. There is a problem that it causes inconvenience to all callers.

Therefore, the present invention has been made to solve the above-described problem, a method for providing a personal answering service in an intelligent network exchange, and to connect the personal answering service with a call forwarding service to enable the caller's call to be connected to a new destination. To provide that purpose.

The personal answering service method of the intelligent network switching system according to the present invention for achieving the above object includes a personal answering service registration procedure and a personal answering service execution procedure;

The personal answering service registration procedure includes: (a) at the service exchange, in response to a personal answering service call request from a first subscriber, notifying a personal answering service registration; (b) generating, at the service control system, a signal for transmitting a first announcement broadcast relating to the registration of the personal answering service to the first subscriber according to the personal answering service registration notification; (c) in the intelligent information providing system, providing a first announcement to the first subscriber according to the announcement broadcast signal; (d) in the intelligent information providing system, storing information provided from the first subscriber in accordance with the first announcement;

The personal answering service execution procedure may include (e) at the service switchboard, notifying that the second subscriber is absent when a call from the second subscriber to the first subscriber is confirmed that the second subscriber is absent. Notifying service execution; (f) generating, at the service control system, a signal for transmitting a second announcement broadcast associated with the stored information according to the notification of execution of the personal answering service; (g) in the intelligent information providing system, providing the stored information to the second subscriber in response to the second announcement broadcast signal.

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

1 is a block diagram of an intelligent network switching system for performing a personal automatic response service method according to the present invention, an intelligent network service switching point (SSP) 120, a service control system (SCP) ( 130), Intelligent Peripheral (IP) 140.

SSP 120 is an electronic exchange that connects a service user with an intelligent network. The SSP 120 recognizes an intelligent network service call in a call user's call, connects the call to a desired destination according to information required for processing the intelligent network service call, and calls or calls. Stores the called number internally.

SCP 130 has service logic and data that manage the whole process of intelligent network service, and can provide various intelligent network services with one SCP or use different SCP for each service. According to the present invention, the SCP 130 forms a bearer channel between the subscriber 110 and the IP 140 according to the recognition result of the intelligent network service call by the SSP 120, so that the subscriber 110 receives the subscriber's own missed message. Providing an announcement broadcast to be recorded in IP 140, and when the subscriber 110 is absent, the missed message recorded in the IP 140 is provided to the caller 150. In addition, the SCP 130 optionally provides the subscriber 110 with an announcement regarding the setting of the call forwarding service to the IP 140 in connection with the missed message recording service, and when the caller 150 wants to forward the call. It is connected to the call forwarding number set in the IP (140).

IP 140 is connected to one or more SSPs 120 and SCP 130 via a signal network, and has customized announcements, speech recognition, speech synthesis, voice recordings, dual ton multi-frequency (DTMF) It has resources such as digit collectors, protocol converters, etc., and provides flexible interaction between users and intelligent networks. IP 140 provides the subscriber 110 with a broadcast to guide the recording of the missed message and the setting of the optional forwarding number as described above, and the recording and the forwarding number of the missed message provided from the subscriber 110. It performs the setting of, provides the recorded missed message to the caller 150, and provides a guide broadcast relating to the caller's call to the call forwarding number in accordance with the caller 150's request.

The method for providing a personal answering service in the intelligent network of the present invention having the above-described configuration will be described in more detail with reference to the flowchart of FIG. 2.

Referring to FIG. 2, the method of the present invention includes two procedures, that is, a personal answering service setting procedure of an intelligent subscriber, and a personal answering service executing procedure.

In the personal answering service setup procedure, subscriber 110 attempts a personal answering service call by dialing a service access code (SAC) to SSP 120 (step 302).

The SSP 120 then sends the SAC, service code and subscriber number to the SCP 130 in an initial detection point (IDT) in response to the subscriber 110's personal answering service call request. Notify the answering service procedure (step 304).

SCP 130, upon notification of the private autoresponder service procedure from SSP 120, provides a PA (Analyze PA) / prompt collect user information (PUCI) command to IP 140. (Step 306), establish a bearer channel between subscriber 110 and IP 140.

IP 140 transmits a recording broadcast to the subscriber through the bearer channel according to the PA / PUCI command of SCP 130 and collects information input from the subscriber 110 according to the recording (steps 308 and 310). . In this case, the recording broadcast provided to the subscriber 110 may be, for example, the message "1 if you want to record a guide broadcast, 2 times if you want to set up call forwarding, press 3 times if you want to cancel call forwarding". When any number is dialed from the subscriber 110 according to the announcement, an operation corresponding to the number is performed. For example, if the number "1" is input from the subscriber 110, the missed message provided from the subscriber 110 will be recorded and stored, and if the numbers "2" and "3" are sequentially input from the subscriber 110, IP 140 transmits a recorded message, for example, an announcement " press desired call forwarding number " to subscriber 110 again, and internally stores the forwarding number dialed from subscriber 110. Complete the procedure for setting up a personal answering service.

Then, with the private autoresponder service registered, if any other subscriber 150 attempts to make a call to subscriber 110 and is absent (step 312), SSP 120 sends an IDP indicating that no response has occurred. Send to SCP 130 to begin execution of the personal answering service (step 314). At this time, the IDP includes the service code and the called subscriber number.

In response to the IDP from SSP 120, SCP 130 generates a PA / PCUI to IP 140 and establishes a bearer channel between subscriber 150 and IP 140 (step 316).

IP 140 transmits the announcement to the subscriber 150 through the bearer channel according to the PA / PCUI from the SCP 130, and determines whether the call is forwarded according to the response of the subscriber 150 corresponding to the announcement. (Step 318). At this time, the announcement broadcast provided from the IP 140 to the subscriber 150 may be, for example, a message "Press 1 to listen to the subscriber's recorded content and press 2 to call forward." According to the announcement message, an operation corresponding to the number selected by the subscriber 150 is executed.

For example, when the subscriber 150 hears the missed message of the subscriber 110 corresponding to the number "1", and enters the number "2" again in succession, the SCP 130 sends a CONNECT command to the SSP 120. (Step 320), the connection between the subscriber 110 and the subscriber 150 by connecting the call of the subscriber 150 to the destination corresponding to the call forwarding number set in the IP 140 according to the SSP 120 CONNECT command Is made (step 322).

Therefore, since the call forwarding service can be executed in addition to the personal answering service in the intelligent network switching system according to the personal answering service method of the present invention, the user can reduce the economic burden by not having an individual answering phone. In addition, there is an advantage that can improve the convenience to the user because it provides a call forwarding service that the existing answering machine can not provide.
