That is, data transmission between the two networks is possible through the interworking gateway, and service control transmission is also possible.

In addition, AIN IP provides the necessary media conversion function and Internet interworking function to implement various services that the telephone network and the Internet can provide by interworking. Also, AIN IP provides web information providing service to telephone users through interaction between network components. To do it. In other words, AIN IP receives web information requested by user through interworking gateway, synthesizes text format information into voice and transmits it to user through telephone line, and from intelligent network service control system (SCP). It receives the media conversion request and sends the converted information through the appropriate channel and reports the result.

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

1 is a network structure diagram of the present invention for enabling a telephone user to receive a web information providing service on the Internet using an intelligent information providing system.

As shown in the figure, the network structure of the present invention largely includes an Internet component, an intelligent network component and an element for interworking the Internet and the intelligent network.

That is, an Internet component, an Internet Voice Access to Contents (VAC) server provided by an Internet Information Provider (ISP) and providing web contents to be heard by a telephone user; Intelligent Information Provision System (IP) with Special Resource Function (SRF) for user interface during service execution, Service Control System (SCP) with Service Control Function (SCF) for performing requested service, Service data system (SDP) equipped with service data function (SDF) to manage necessary data, and service exchange function (SSF) and call control function to detect intelligent network service from the basic call processing of exchange and request service execution. An intelligent network including a service switch (SSP) equipped with a (CCF); And a service control gateway function (SC GF) that performs a connection function for transmission and reception of control signals and data between the Internet VAC server and the intelligent network.

As described above, in the network structure, web contents to be delivered to the telephone user by the VAC server may be variously constructed according to the demand of the service user such as weather information, stock information, new information, and traffic information.

The VAC server interworks with the intelligent network through SC GF, a gateway function that connects the Internet and the intelligent network. The VAC server is the end point on the Internet that goes through the Internet for intelligent service requests or access to Internet services from the intelligent network.

SC GF is a relay that connects the transmission and reception of control signals and data between two networks for VAC service.

In addition, IP, an intelligent network component, has a function of receiving web information of an Internet VAC server and a media conversion function of converting text to voice, and add a voice recognition function to IP to enhance service convenience. have.

As an interface between the network configuration nodes of the present invention, the matching between the intelligent network nodes, that is, SCP-SDP, SCP-IP, and SCP-SSP, uses an intelligent network application protocol (INAP). The TCP / IP protocol is used to transmit textual information between SC GF and IP, and between SC GF and SCP. In addition, ISUP (ISDN User Part) protocol is used to establish No.7 signaling information and bearer channel between IP and SSP.

2 shows a procedure for providing a web user with web information using the network structure as described above.

In the figure, a procedure for servicing Internet web information to a telephone user using AIN IP is roughly divided into a service registration procedure and a service provision procedure.

First, the service registration procedure will be described.

The ISP, which wants to provide VAC service to the telephone user by using the AIN IP, establishes a VAC server, and then the VAC server requests registration of the VAC server to the SC GF (S1). At this time, when the IP address of the VAC server and the type of information to be provided are informed, the SC GF generates a corresponding service profile and registers it with the SDF, which is the database system of the intelligent network, via the SCF (S2).

When a new VAC server is registered in the SDF through this procedure, the ISP operator operating the VAC server can notify the Internet users that the VAC service has been published through a web advertisement.

When the service exchange function / call control function (SSF / CCF) detects a specific service request of a telephone user, the VAC service registered in this way is controlled by the service control function (SCF) and the user desires the service data function (SDF). Selected VAC server that provides the information type, SRF received the text information of the desired information type from the selected VAC server through the service control gateway function (SC GF) and synthesized the voice after voice synthesis Is provided to the telephone user by sending it through the service exchange function / call control function (SSF / CCF).

This will be described in detail.

In the following description, the connection between the telephone user and the SSF / CCF is omitted on the assumption that the connection is made through the LE (CCF).

Initially, the telephone user presses a specific Service Access Code (SAC), such as when attempting another intelligent network service to receive VAC service (S3).

Then, the SSF / CCF detects that the VAC service request is received by looking at the SAC and sends an InitialDP operation to the SCF (S4). Accordingly, the SCF selects an appropriate SRF and transfers its address to the SSF / CCF to indicate connection (S5).

The SSF / CCF attempts to request a bearer channel with the SRF by sending an Initial Address Message (IAM) with reference to the SRF address received from the SCF (S6). The SRF then confirms that there are available resources, sends an address complete message (ACM) to the SSF / CCF to establish a channel connection, and provides service by sending an Assist Request Instruction (ARI) operation to the SCF. Notify that it is ready (S7).

Receiving the ARI operation, the SCF sends a Prompt and Collect User Information (PCUI) operation to the SRF and requests the user to collect specific information contents (S8).

In response, the SRF sends an announcement (eg, "Please tell us what kind of web information service you want"), and the user refers to the type of information (eg, securities information) you want to search (S9). At this time, the voice recognition function is activated to detect the type of information pronounced by the user and transmit the collected user information (CUI) including the service code value to the SCF (S10). Here, instead of using the voice recognition function in collecting the type of information that the user wants to search, the user may listen to the service contents as a guide broadcast and collect and transmit the digits corresponding to the corresponding service code.

The SCF requests the SDF to search the VAC server using a service type code (eg, securities information) code requested by the user as a key value, and the SDF transmits the search result to the SCF (S11 and S12). The SCF can flexibly select available VAC servers by date and time by referring to the VAC server search results sent by the SDF.

The SCF selects a VAC server to provide web information, and then sends an Initiate Service Attempt (ISA) operation to the SC GF (S13).

The ISA operation is a detailed parameter that contains the IP address of the VAC server, the VAC service identifier, the service type code (eg stock information), the Internet Connection Identifier (ICI), and the SRF address. ICI is assigned by one SCF whenever an internet interworking service call instance occurs, and is used to identify service call processing provided through interworking functions of SC GF, SRF and SCF.

When the SC GF receives the ISA operation, the SC GF stores the ICI and SRF addresses, and then transmits an IP address, a service type code, and an ICI to the VAC server, and requests transmission of corresponding web information for the VAC service (S14).

The VAC server delivers the text information corresponding to the service type code to the SC GF with the ICI (S15). SC GF sees the ICI value of the received data and transmits the data to the corresponding SRF (S16).

Subsequently, when the data reception is completed, the SRF transmits a Transform Request Instruction (TRI) operation including an ICI to the SCF (S17). The TRI operation is an operation that requires the SCF to send a command operation for the service after the SRF completes data reception from the SC GF for the Internet interworking service. The TRI operation is newly added to the existing INAP operation.

At this time, the SCF identifies the service call by ICI and transmits a Send Message (SM) operation according to the corresponding service logic to the SRF (S18). The SM operation is composed of ICI and Request Announcement Complete Indication (RACI), that is, to inform the SCF of the completion of the message transmission, and the kind of media transformation to be performed by the SRF, that is, text-to-speech (TTS). It includes a parameter indicating.

Upon receiving the SM operation, the SRF drives the speech synthesis function of the text received from the SC GF and sends the synthesized speech to the telephone user through the SSF / CCF (S19). That is, the web information provided by the VAC server is synthesized by voice and transmitted to the telephone user.

After the announcement (voice transmission for web information), the SRF sends a Specialized Resource Report (SRR) operation to the SCF to inform that the SM operation has been successfully performed (S20). The SCF may then continue to use the SRF by sending an operation to send an announcement asking whether to proceed with other services or terminate the use of the SRF.

The procedure for releasing a bearer channel between SRF and SSF / CCF to terminate the VAC service requested by the telephone user is as follows.

That is, the SCF sends a disconnect forward connection (DFC) operation to the SSF / CCF to instruct to release the connection with the SRF (S21). The SSF / CCF sends a REL (Release) message to the SRF to request release (S22), and the SRF sends a Release Complete (RLC) message to the SSF / CCF to inform completion of the release (S23).

As described above, the present invention configures a network including a gateway for interworking with the Internet and an intelligent network, and adds Internet data transmission / reception function, speech synthesis function, and voice recognition function to AIN IP to a telephone user without Internet connection. Web information can be provided.

In addition, the present invention provides a convenience that a person with a physical disability (particularly visually impaired) or a person with a physical disability (especially a visual impairment) can be voice-informed through the telephone by using various useful information.

It also enables the creation of new value-added services for telephone network operators and Internet information providers.

The technical spirit of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only and not intended to limit the present invention. In addition, it is obvious that any person skilled in the art can make various modifications and imitations without departing from the scope of the technical idea of the present invention.
