Description

How to provide click fax transmission service in next generation intelligent network

The present invention relates to a next generation intelligent network service providing technology, and more particularly, to a method for providing a click fax transmission service in a next generation intelligent network.

The existing next-generation intelligent network is a network concept based on the Public Switched Telephone Network (PSTN) / Integrated Service Digital Network (ISDN), and it was possible to use the intelligent network service using a telephone terminal. The service was not available. That is, a service user connected to the Internet could not deliver a fax message to a fax terminal not connected to the Internet.

In recent years, communication services through Internet terminals are gradually increasing, and the types thereof are also diversified. Therefore, solving the demand for a technology capable of providing a click fax transmission service in a next generation intelligent network is an urgent problem.

The present invention is to provide a method for providing a click fax transmission service capable of transmitting a fax message from a service user using an internet terminal to a fax terminal not connected to the internet.

The present invention relates to a service control system (SCP), a service switching point (SSP), and an intelligent information providing system (IP :) in which an intelligent network service request for a click fax transmission from an Internet terminal is a next-generation intelligent network element. Intelligent Peripheral) is proposed. That is, by suggesting the intelligent network message structure transmitted and received between SCP or IP, which is an intelligent network element, and the Internet gateway station connected to the signal network, and the process of clicking fax transmission service in each network element, the user of the Internet terminal service clicks a specific button. In addition, the present invention implements a click fax transmission service capable of transmitting information of a web page to a desired fax terminal.

Accordingly, in order to achieve the above technical problem, the present invention provides a method for providing a click fax transmission service in a next generation intelligent network, comprising: a first step of driving the intelligent network service logic; A second step of collecting information to be transmitted from a service user using an internet terminal and storing the information in a intelligent information providing system; Establishing a channel between the intelligent information providing system and the incoming fax terminal; And a fourth step of transmitting the fax data stored in the intelligent information providing system to the called fax terminal.

Hereinafter, preferred embodiments of the present invention will be introduced so that those skilled in the art can more easily implement the present invention.

1 is a diagram illustrating a network configuration in which a next-generation intelligent network to which a click-fax transmission service is to be applied and the Internet are linked according to the present invention, wherein a user of a click-fax transmission service having an Internet terminal clicks a specific button to perform an intelligent network service. Upon request, the Internet gateway station 2 detects it, encodes it into an intelligent network message that SCP 3 can receive, and sends it to SCP 3. The Internet gateway station (2) is a network element that mediates the Internet and the intelligent network, defends against illegal use and attacks from the Internet, and acts as a mediation function between the protocols used in the Internet and the intelligent network. SCP (3) is a network element that holds the intelligent network service logic and data necessary to perform the service. When SCP (3) receives the click fax transmission service request from the Internet gateway station 2, it operates the intelligent network service logic. IP (4) is a network element that provides service users with special resources such as voice guidance, dual tone multi frequency (DTMF) collection, voice recognition, message reception, media conversion, and so on. Collects the data to be delivered from the service user, and converts the fax data into fax data, and sends the converted fax data to the incoming fax terminal 6 via the SSP 5 upon request from SCP 3; do. The SSP (5) detects the intelligent network service request from the PSTN / ISDN terminal and delivers it to the SCP (3), and upon request of the SCP (3), establishes a call path with a specific PSTN / ISDN terminal and the IP (4). Element.

2 is a diagram illustrating a procedure in which the network elements shown in FIG. 1 process a click-fax transmission service according to an embodiment of the present invention. Attach the document to be sent to the network, enter the incoming fax terminal number, click the service request button, and the Internet gateway station sends the Internet intelligent network service processing request message to the SCP (11).

SCP then analyzes the Internet intelligent network service processing request message and checks whether it can execute the intelligent network service logic program, and if the service cannot be provided, sends an Internet intelligent network service processing request failure response message to the Internet gateway station (12). The process ends. If the SCP is able to process the service, it sends a request message collection request message to the Internet gateway to store the document to be sent by the service user on the IP (13). Next, the Internet gateway sends a data transmission message containing information of the document that the service user wants to send to the incoming fax terminal at the IP designated by SCP (14). IP receives the document carried in the data transmission message, converts it into fax type data, stores it, assigns the stored message identification number, and transmits the data transmission response message to the Internet gateway (15). If the IP fails to receive media convertible data from the Internet gateway, or converts it to fax type data and stores it, the Internet gateway sends an outgoing message collection response to the SCP (16), and the SCP sends it to the Internet gateway. The intelligent network service processing request failure response message is sent to the station (12), and the service processing ends. If the Internet gateway receives a data transmission success response message from the IP, it transmits a transmission message collection success response to the SCP (17).

Subsequently, the SCP sends a message to the SSP to the incoming fax terminal requested by the service user (18). The SSP connects and calls the received incoming fax terminal and the call path (19). If the incoming fax terminal does not respond normally and is busy or unresponsive, it reports a busy or non-responsive event to the SCP (20), and attempts to connect with the incoming fax terminal at regular intervals for the number of retries defined in the service logic (21). ), And perform step 19 again. If the incoming fax terminal does not respond normally until the number of retries is exceeded, SCP sends an intelligent network service processing request failure response message to the Internet gateway (12) and terminates the service processing.

Upon receiving an event that the incoming fax terminal has responded normally from the SSP (22), the SCP sends a connection request message to the SSP with the IP containing the fax type data (23). The SSP establishes a bearer channel with the IP (24), and the IP informs the SCP that the bearer channel with the SSP is connected and sends a command request message for resource provision (25). When requested to send a fax type message from the SCP to the destination fax terminal (26), the IP sends the fax type message over the connected bearer channel (27), sends a response message to the SCP (28), and then The connected bearer channel connection is released (29). Receiving a fax transmission response message from the IP, SCP transmits an Internet intelligent network service processing response message to the Internet gateway station (30), and terminates the service processing.

Table 1 below shows the structure of an intelligent network message transmitted and received between the Internet gateway and SCP, and between the Internet gateway and IP, which is designed for processing the click fax transmission service described in FIG.
