How to provide a phone chat service using a display-mounted phone {DISPLAY-ATTACHED PHONE-CHATTING SERIVCING METHOD}

The present invention relates to a method for providing a telephone chat service using a display-mounted telephone and a computer-readable recording medium recording a program for realizing the method. In particular, the present invention provides a telephone chat service to a telephone network subscriber using a telephone equipped with a display. A computer-readable recording medium having recorded thereon a method for providing the same and a program for realizing the method.

Until now, communication methods between people in remote locations can be divided into two types: data communication through a personal computer (PC) and voice-based communication through a wired or wireless telephone.

The voice-based communication method through wired and wireless telephones has been gradually developed, and a simple menu selection function using a dual tone multiple frequency (DTMF) tone recognition program generated when a user presses a number button on a telephone is already commercially used. Multimedia complex communication (e.g. next generation mobile communication (IMT2000) system) that can easily send and receive more complex data and still or moving image through information compression technology and technology development of transmission network itself, digitalization of communication network, and mounting of display ) Is showing a trend to develop. Communication through PC is also performed by sending and receiving text and data files through PC communication or the Internet. Using voice and video peripherals (sound card, speaker, monitor screen, PC camera, etc.) attached to PC, Multimedia communication methods (eg, real audio player, web browser, internet phone, web camera, etc.) that can simultaneously send and receive video are emerging. The multimedia trend of data communication and voice-based communication is especially reflected in the chat service method between PCs, and a multimedia chat method in which text, voice, and video are transmitted through a data communication network including a PC communication network and the Internet (eg, Microsoft's NetMeetings are emerging. However, the method of chatting via telephone has not yet been developed into a multimedia type using a display. In recent years, a text chatting service has been developed and commercialized in a personal communication system (PCS) terminal. Given the increasing trend of wireless handsets, telephone chat services will be used primarily through wireless handsets.

The closest example of a phone chat service using a display is a phone response service such as phone marketing, call center service for corporate after-sales service, or ponting. In these services, a menu-type message is provided continuously so that a person can enter a menu number or a customer number, and then connect with a desired person or listen to or input necessary information accordingly. It takes a lot of time because the user of the telephone service needs to listen to the voice information according to the pre-written scenario step by step, and the customer has to listen to the mechanically synthesized voice message manually and then the desired person or the desired information. Because of the fact that it is very different from the natural communication method between people, it is easy to give a bad first impression in terms of service quality.

In addition, since the customer cannot grasp the entire telephone application menu at a glance, there was a problem that it is not possible to shorten the time to find the desired menu items.

Telephone response service maintains high necessity in the field of public service in the future with regard to reducing communication, service and marketing cost of company, but as mentioned above, it is often inconvenient for customers accessing service. It is not easy to completely solve the inconvenience by using the voice menu only. Therefore, there are many causes that hinder the growth of the telephone service market. Therefore, the telephone service provider provides the voice information and the video information that complements the voice information through the display mounted on the telephone terminal for minimizing the customer inconveniences of the voice-only service and providing prompt service. Action is required.

The present invention has been made to solve the problems described above, the call of the service applicant who wants the telephone chat service through the call number detection of the outgoing call number of the telephone network subscriber using the phone equipped with the display in the telephone chat server The purpose of the present invention is to provide a method for providing a telephone chat service and a computer readable recording medium storing a program for realizing the method.

The H.323 standard of the Telecommunication part of International Telecommunication Union (ITU-T) is an umbrella standard that references many other ITU-T Recommendations. H.323 provides system and component descriptions, call model descriptions, and call signaling procedures. H.225.0 describes media (audio and video) stream packetization, media stream sync, control stream packetization, and control message formats. H.245 describes the messages and procedures used to open and close logical channels for voice, video and data, capability exchange, mode requests, control, and indication. These are recommendations governing H.323 end-to-end communications and the operation of H.323 devices.

Other recommendations are referenced for voice and video coding. In speech coding, G.711 is mandatory and G.722, G.728, G.723.1, and G.729 are selectable. In image coding, H.261 QCIF mode is mandatory and H.261 CIF and all H.263 modes are optional. In addition, the recommendations of the T.120 series are used for data applications.

H.323 is based on the Real-Time Protocol / Real-Time Control Protocol (RTP / RTCP) of the Internet Engineering Task Force (IETF). In H.323, extensions for call signaling and additional voice and video coding algorithms are provided.

The H.323 terminal provides real-time two-way voice, video, and data communications. This Recommendation defines call signaling, control messages, multiplexing, voice codecs, video codecs, and data protocols. Like other ITU-T Recommendations, H.323 does not specify voice or video devices, data applications, or network interfaces, but mandates certain capabilities to provide a minimum level of interoperability. .

1 is an exemplary communication link configuration via an exchange system between a display-equipped telephone terminal and a telephone chat server to which the present invention is applied, and shows a display subscriber-type telephone terminal 100, a subscriber circuit 101, and a number inside an exchange. A translation processor 102, a modem pool 103 for a telephone chat server, a terminal server 104 for a telephone chat server, a local area network (LAN) 105, and a telephone chat server 106 are provided.

As shown in the figure, the outgoing call of the subscriber's display-equipped telephone terminal 100 is routed to the telephone chat server 106 through the number detection of the number translation processor 102 in the telephone network switching system, and, if necessary, the relay network. Pass through

The telephony chat server 106 receives a communication packet of a telephony chat service request call coming from a terminal server 104 through a local area network (LAN) using an Internet Protocol (IP).

Telephone chat server 106 in accordance with ITU-T (Telecommunication part of International Telecommunication Union) standard H.323 for audio conferencing and video conferencing on IP-based networks. Calls setup and management (using Q.931 signaling, standards such as H.225.0, H.245), real-time data transmission, conference registration / admission and bandwidth allocation, and address lookup ( Gatekeeper functions for address lookup, call routing, H.323 and H.320 terminals (for N-ISDN), H.321 terminals (for B-ISDN), and H.324 terminals (for general PSTN) Gateway function for interoperability support (network or signal conversion) with communication terminals on networks that use other voice / video protocols, such as H.322 terminals (for IsoEthernet), H.310 terminals (for ATM), etc. MCU (Multipoint Control Unit) function that mixes audio and video It is danghage.

Accordingly, the subscriber's display-mounted telephone 100 and the telephone chat server 106 maintain communication links necessary for a telephone chat by communicating with each other according to the H.323 standard through the telephone network. In addition, the telephone chat server 106 handles multiparty call control and handles voice / video stream handling, including synchronization and buffering.

The ability to shuffle the voices of telephone subscribers chatting for the scalability of the telephony chat server 106 may be implemented on a Digital Signal Process (DSP) card rather than on the server's mainboard. If necessary, the service user can dial a pre-determined number, detect the DTMF tone, and have the phone chat menu appear on the user's display, allowing him or her to stop chatting or move to another chat menu.

The first call processing function performed by the telephone chat server detects that a new telephone chat request call has been received and the message that the telephone chat request terminal provides a chat service only for a video terminal capable of operating according to the H.323 standard. To send the call to the call and the other party's intention to continue chatting, by asking a message such as "Press 0 to continue" to identify the DTMF tone. After the confirmation is made, the telephone chat menu is exported to the display of the service requester's terminal.

2 is a flowchart illustrating a method for implementing a telephone chat service through detection of an outgoing call to a telephone chat service telephone number of a telephone network subscriber.

As shown in the figure, a telephone network subscriber sends a call to a telephone number previously designated for a telephone chat service. At this time, the number translation processor of the switching system is responsible for call routing to send this call to the modem pool of the nearest telephone chat server by a predetermined program.

The demodulated digital signal of the server modem pool is made into a communication packet for a LAN via a terminal server and reaches a telephone chat server connected to the LAN.

The telephone chat server establishes a communication link in a state capable of interoperation with a telephone terminal connected to the telephone network through call processing by the gateway function of the H.323 standard.

Through the configured communication path, the telephone chat server displays the telephone chat service menu on the display of the telephone handset, and the user presses the numeric or special character buttons ('1' to '9' and '0', '*' and '#'). It can be used to select a menu so that the DTMF tone voice signal at the time of pressing is discriminated to provide a service of a corresponding menu. This includes entering the desired chat room, stopping the chat, displaying the current chat room status, and providing useful or convenient information to other users. In this process, the voice streams of the users of the chat room are mixed by the chat server as in a conference call.

When a DTMF tone signal is received to terminate the chat service, the user spreads a message indicating that the user is discontinuing the chat service on the display of the chat party and disconnects the communication link.

Compute and store billing data according to a fixed rate system for the telephone number that provided the service.

This will be described according to the flow of the drawings.

First, a program for routing an outgoing call to a specific number designated for a telephone chat at an exchange of each telephone station is executed (201). Such an example is defined as a telephone chat for a specific number, such as 01410, which is a number for the existing computer communication. When an incoming call is received, it is determined to be a call for a telephone chat, and is processed by the number translation processor of the exchange.

In operation 202, it is determined whether the received telephone number of the outgoing call entering the subscriber circuit is a telephone chat number. This is done by the number translation processor of the exchange.

If it is determined that the telephone chat number is not, the exchange handles the call as a general telephone call (203).

If it is determined that the telephone chat number is located, the call is routed to the place where the telephone chat server is located (204), and the call is routed through the telephone network from the modem pool for the chat server connected to the telephone chat server through the LAN with the terminal server. Receive (205). The modem pool also converts the telephone chat server's response to each outgoing call into a signal on the telephone line through the telephone network.

Upon receiving the outgoing call, the modem pool's modem converts this call into a digital signal and sends it to the terminal server, the preprocessor of the telephone chat server (206).

The terminal server converts the input digital signal into an IP packet that communicates on the LAN and sends it to the telephone chat server (207). The terminal server also receives a LAN packet of the telephone chat server and converts the LAN packet into a digital signal to a modem connected to an outgoing call that the telephone chat server responds to (207).

The telephone chat server provides a service such as multiplexing a telephone chat menu and telephone voice according to H.323 (telephone standard over a LAN) for a plurality of IP packets (telephone chat calls) coming through a LAN card.
