The present invention relates to an automatic answering agent service method in a high-intelligence network, particularly a public telephone network subscriber who does not have an answering machine in the high-intelligence network to receive a voice message stored in the intelligent information providing system when the user is absent or busy. It relates to an automatic response agency service method of.

In modern times, the development of communication network technology has emerged the concept of intelligent network, and the initial intelligent network has been established to provide the intelligent network service. However, the intelligent network service needs to be diversified according to the needs of communication users.

In addition, the intelligent network is evolving from the initial intelligent network to the highly intelligent network, and standardization work is underway around the International Telecommunication Union-Telecommunication Standardizaton (ITU-T).

Therefore, there is a need for an automatic answering agent service that allows a caller to record a voice message in an intelligent information providing system and deliver it when the called party is absent or busy using an intelligent information providing system rather than a recording device attached to a telephone.

In the existing general telephone service, the telephone network subscriber having the telephone can receive a voice message when the called party is absent only when the answering machine is equipped with a recording device capable of recording voice. Voice can be sent and received by using the connected independent information providing system, but the answering machine currently in use cannot record a voice message when the called network subscriber is busy.

Independent information provision system allows the service user to record a voice message and the service subscriber can take it out and listen to it, so indirect calls through the recorded voice message can be made between the service user and the service subscriber. In this case, there is no function of recording a message on the recording device, and the service can be provided to only a few subscribers. That is, wide area service is impossible.

However, not only the expectations and desires for communication are varied for each user, but also the intelligent network concept has emerged in order to satisfy their needs in order to be provided with services at a low price, thereby enabling intelligent network services.

By using the highly intelligent network service exchanger, service controller and intelligent information system, if the service user can't make a call anywhere at any time, even a regular telephone network subscriber who does not have an answering machine can store the voice message in the intelligent information system and receive it. You need a service that can.

In order to establish a technical foundation for early settlement of the highly information society by spreading and distributing various intelligent network services at an early stage, the existing network and the integrated service digital network (hereinafter referred to as ISDN) are interconnected with the intelligent network. Standardization of advanced intelligent network service switch (hereinafter referred to as SSP), service controller (hereafter referred to as SCP), and intelligent information providing system (hereinafter referred to as IP) are being standardized.

Accordingly, an object of the present invention is to provide an automatic answering agent service method in an advanced intelligent network that enables a public telephone network subscriber who does not have an answering machine to receive a voice message stored in an intelligent information providing system when he or she is absent or busy. have.

The present invention for achieving the above object, Service Control Point (SCP) Service Management System (Service Management System: SMS), Signaling Transmitter (Signal Transfer Point: STP), Advanced Intelligent Network Service Switching (SSP) In the intelligent response system (Intelligent Peripheral: IP), Local Exchange (LE) as a main network element in the auto-response agent service method, the SCP enters a service identification number ( Verifying whether a service is provided to the SAC and the telephone mailbox number (MN), and determining whether the type of the service identification number (SAC) is a service subscriber or a non-service subscriber; A second step of verifying by receiving a password from a caller if the type of the service identification number is a service subscriber and performing an absence registration / deregistration according to a caller's selection; And a third step of performing voice message transmission and call connection when the service subscriber is absent, unanswered, and busy when the type of the service identification number is a non-service subscriber.

In other words. The automatic answering agent service of the present invention having the above process is a service that can receive voice messages when the general telephone network subscriber is busy or absent without having an automatic answering phone, and is required from an existing telephone network or an integrated information network. During the call, the SSP recognizes the call requiring the intelligent network service, collects the information, routes the call to provide the auto-response service, and inquires the data necessary for service processing with the SCP. To the SSP.

The IP broadcasts announcements to the service users and provides the SCP with the digit information that SCP needs to perform the service logic. IP can also store voice messages under SCP's service logic and forward them to service subscribers.

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

1 is a block diagram of an intelligent network to which the present invention is applied.

As shown in the figure, the intelligent network necessary to implement the auto-response service is based on the currently implemented intelligent network system and the implementation method of the systems under study. The SSP (4), the SCP (1), and the service management system (Service Management) System (hereinafter referred to as SMS) (2) and Signaling Transfer Point (hereinafter referred to as STP) (3) as main network elements.

The signaling method between the SSP 4, the SCP 1, and the IP 5 assumes a scenario in which the SCP 1 controls resources of the IP 5 through the SSP 4, and the IP 5 is a service. In order to allow the user to conveniently use the service, resources such as announcement broadcasting and voice signal processing are reserved so that additional information can be collected from the service user according to the service scenario or guided for incomplete calls. It has special resources to provide service providers so that service users can record voice messages.

The SSP 4 recognizes a service user's automatic response agent service request, triggers the corresponding service logic, requests the SCP 1 to process the service, and relays between the service user, SCP 1, and the IP 5. It is responsible for the routing function to IP (5).

In the present invention, the SSP of the intelligent network configuration is assumed to be a toll, not a local one, and processes an intelligent network service request from a local exchange (hereinafter referred to as LE) 6, and SCP (1) is responsible for providing service logic and service. It is responsible for processing and controlling the auto responder service with the necessary data.

In addition, IP (5) has a network resource related to the service processing, under the control of SCP (1) through the SSP (4) to provide network resources to the service user and collect or retain the input data from the service user It is in charge of the function, SMS (2) is operated by the network operator and is responsible for the management function to change the data and logic necessary to perform the service.

And, STP (3) is in charge of the function of transmitting the No.7 message system (Signaling System: SS) between the SCP (1) and SSP (4). That is, the signaling method between the SSP 4 and the SCP 1 exchanges messages using SS No. 7, and the signaling method between the SSP 4 and the IP 5 is a digital subscriber signal (DSS). Send and receive messages using No.1.

In addition, the signaling method between the SSP 4 and the LE 6 uses R2, a telephone user part (hereinafter referred to as TUP), an ISDN user part (hereinafter referred to as an ISUP), and a telephone network. Signaling between subscribers 7 (8) and LE (6) DSS1 or Dual Tone Multi-Frequency (DTMF).

2a to 2b are diagrams showing a usage number system in an automatic answering agent service according to the present invention. Basically, a service identification number (hereinafter referred to as SAC) 21 and a telephone mailbox number (Mail Number) are shown. : MN (22), password (23), the function selection number (24), and the like, special number may be additionally used to improve the quality of service, such as enhanced security features, the addition of special services.

That is, the system of the service use number provisionally includes three-digit SAC (21) 25, seven-digit MN (22) 26, four-digit password (23), one-digit function selection number (24), etc. The number input may be divided into two cases as shown in the figure according to the service procedure.

The service provider (network operator) must define two SAC (1) (25) in order to recognize the autoresponder service request from the service subscriber and the non-subscriber. In the case where the user wants to be provided with the service by inputting 23, the service provider performs the verification of the MN 22 and the password 23 and selects a function selection number 24 if it is a valid number to provide the desired service. And charging the MN 22.

This is used to leave a voice message in the service subscriber's telephone mailbox. SAC 2 (25) provides the SAC required for voice message delivery and call connection when the service subscriber is absent, unanswered and busy as shown in FIG. It is defined as.

3 is a flow diagram of an answering agent service procedure according to the present invention. When a caller attempts an answering agent service by dialing SAC and MN (301), the SSP recognizes an intelligent network call and requests an intelligent network service process to the SCP. (302)

The SCP, when the SSP requests the intelligent network service processing, drives the automatic response agent service logic and verifies whether the service is provided to the SAC and the MN using the subscriber table (303), and confirms the verification result of the SAC and the MN. 304. If the verification result is successful, the SAC type is determined (305) to continue service according to the SAC type.

If the SAC type is SAC1, the SCP requests the connection between the IP and the sender to the SSP, and sends a password input to the IP and collects digit information (306), so that the SSP connects between the IP and the sender and the IP enters the password. After transmitting the announcement and collecting the digits, it is returned to the SCP, and the SCP verifies the collected digit information, that is, the password (307).

After verifying the verification result of the password (308), if the result is successful, the SCP requests the IP to send the missed registration / deregistration announcement and the digit collection, and the IP sends the missed registration / deregistration announcement and the digit. And return it to the SCP (309), the SCP uses the collected digit information to update the missed registration / deregistration data of the subscriber profile (310).

On the other hand, if the verification result of the password is unsuccessful, SCP determines whether or not the number of retries exceeded (314), and if the number of retries does not exceed the allowance, SCP sends a password re-entry announcement to IP and collects digits. After returning the IP, the IP transmits the password re-entry announcement and collects the digit information and returns it to the SCP (315), and the SCP performs verification on the collected password and confirms the verification result of the password. Transition to 308.

And, if the verification result for the SAC and MN fails (304) or exceeds the allowance for the number of retries (314), and if the SCP completes the data update for missed registration / unregistration (310), SCP requests IP to terminate service announcement and requests SSP to disconnect the IP and sender (311).

The IP then sends a service termination announcement to the caller and the SSP releases the connection between the caller and the IP (312), the SCP terminates the service and the SSP terminates the call (313).

On the other hand, in the SAC type determination result (305), in the case of SAC 2, the SCP determines whether or not the absence state by using the absence registration / deregistration data of the subscriber profile (317), when the SCP is in the unregistered state of the SSP The call request status report is requested, and the SSP performs call status report processing (318).

Then, the SCP checks the incoming state (319), if the incoming state is idle, performs the translation of the called number and requests the SSP to connect the called party, the SSP attempts to connect between the caller and the called party (320). After determining whether to answer (321), when the called party responds, the SSP connects the calling party and the called party so that the calling party and the called party can talk to each other (322.)

On the other hand, when the missed state is the missed registration state 317, the incoming state is the busy state 319, or the called party does not respond (321), the SCP requests the SSP to connect between the IP and the caller, and inputs a voice message to the IP. The announcement broadcasts request for collecting voice message information (324).

Then, the SSP connects between the IP and the sender, and the IP collects voice message input announcement broadcast and voice message information and returns the collection time information, message size, sender information, etc. related to the voice message information to SCP, In step 325, the voice message data of the subscriber profile is updated using information related to the voice message information to complete the message receiving process.

Then, after the caller and the called party talk to each other, if the caller or the called party 'hook on (H / On) 323 or the SCP has completed the voice message reception processing (325), SCP terminates service to the IP Requesting the announcement and requesting the SSP to disconnect the IP (326), the IP sends the service termination announcement to the caller and the SSP performs the IP disconnection processing (327), so that the SCP terminates the service and the SSP The call ends (328).

According to the above, the present invention can provide an automatic answering agent service that can store voice messages in an intelligent network instead of an answering machine in an intelligent network composed of SSP, STP, SCP, and IP, which are intelligent network elements, and receive them later. .
