Description

Short service system and method of internet video phone {SMS system of internet visual phone}

The present invention relates to a short message service system and method for an Internet video telephone, and more particularly, to add a short message to video / audio data so that a text message can be transmitted and received, and real-time text chat is possible during a digital video call. The present invention relates to a short service system and a method of an internet video telephone.

Short Message Service (SMS) refers to a service that delivers a limited-length text message from the Internet to a mobile phone or from a mobile phone to a mobile phone regardless of whether a mobile subscriber is busy.

SMS, which can send texts of about 80 bytes (40 characters in English) on the LCD screen of mobile phones, can send messages through resend even if the other party cannot receive the message, such as when the power is turned off. High quality messaging service.

Therefore, the range of personal use to corporate service is continuously expanding and the number of occurrences is exploding, and its application fields are various marketing means such as internet shopping, reservation / booking, logistics, financial sector, real estate, job / job search, and micropayment. It can of course also be used as a supplement to the intranet within the enterprise.

Voice over Internet Protocol (VoIP), on the other hand, refers to a technology for transmitting voice using the Internet's IP layer and is used interchangeably with Internet telephony.

However, the meaning of these two terms differs strictly. VoIP means converting an analog signal into a digital signal and then converting it into packets and transmitting them to the receiving party through the Internet, an IP network. Rather, it supports the services provided by existing telephone networks in all networks (ATM, Frame Relay) that can transmit voice and fax data.

Therefore, when the voice service is used in the internet network instead of the telephone network, the two terms are used identically without any difference in meaning.

In the present invention, the Internet phone means a phone-to-phone method, a PC-to-PC method, and a phone-to-PC method in the VoIP system configuration. The concept can be summarized as follows.

The phone-to-phone method refers to a method in which both the calling party and the receiving party of the telephone can use the existing telephones 1a and 1b as in the case of using a public public telephone network (PSTN).

For example, when making an international call, the caller pays an international fee when the call is made. However, using this method, a call can be made using only the local call rate using the packet network (3).

The PC-to-PC method is a method in which both a sender and a receiver make a call using a computer 4.

Both the sender and receiver need a sound card and a headset of the computer 4.

The PC-to-Phone method refers to a case where a person making a call from a general telephone 1b and a person who receives a call receive a call using the computer 4.

On the contrary, the phone-to-PC method is called, but the two methods are not different in the configuration method.

Since a conventional short message service (SMS) is performed only between a mobile communication network and a PSTN, it is not possible to transmit and receive a short message in an Internet video terminal to which a text message function can be applied.

In addition, in the case of a hearing impairment such as a hearing impaired in a VoIP system, a video (signal) call must be made to communicate each other's intentions.

The present invention has been made to solve the above-described problems, an object of the present invention is to provide a short-term service system and method of an internet video telephone that can transmit and receive a short message using text in addition to the video / voice call using the Internet video terminal There is.

It is still another object of the present invention to provide a short message service system and method for an internet video phone capable of providing another means of communication in addition to sign language by applying a short message function while making a video call with a sign language using an internet video phone.

A call is made through the Internet network 20, and a video call and a short message service are supported. A soft phone 12 to perform, a general telephone (14) where a call is made through a PSTN (22) and a short message service is supported, and a mobile terminal where a call is made through a mobile communication network (24) and a short message service is supported ( 16), and when the short message is received through the transmission Internet video telephone (10a), the SMS server 30 for requesting authentication if necessary, and sends a short message to the corresponding terminal (12, 14, 16), When the authentication request is received from the SMS server 30 and stores the information necessary for authentication, the authentication server 40 for performing the authentication procedure for the sending Internet videophone 10a, and the short message through the other network and the Internet SMS server (30) when received It consists of a gateway 50 for performing the authentication procedure to the receiving general telephone 14 or the mobile terminal 16 in response to the authentication request.

The SMS server 30 stores application programs for various additional services (for example, services communicating with external networks).

The authentication DB 42, which stores information necessary for authentication of the authentication server 40, stores a telephone number, a model, a name, and the like.

The gateway 50 is a network point serving as an entrance to another network. In terms of routing, the Internet network 20 may be a network composed of many gateway nodes and host nodes.

The short service system configuration diagram of the present invention is explained by dividing into a video call and a non-video call.

In the case of a video call, a short message is transmitted / received between the two video telephones 10a and 10b in such a manner that the transmitting Internet video telephone 10a and the receiving internet video telephone 10b are connected to each other.

When the two Internet video phones 10a and 10b are in a call state through the Internet network 20, the video using the international video standard protocol (H.323 / SIP / MGCP / MEGACO) and its own protocol for making a video call. Audio data and the input short text are transmitted together, thereby real-time text chat function is realized.

The video call is not divided into the case of using the same Internet network 20 and the case of using an inner network and a different network (for example, PSTN 22 and mobile communication network 24).

In order to transmit a short message from the sending Internet video phone 10a to the receiving Internet video phone 10b or the softphone 12 using the same Internet network 20, the SMS server sends a short message from the sending Internet video phone 10a. 30 is sent through the authentication server 40 (for example, the gatekeeper) connected to the SMS server 30, and then the short message to the receiving Internet video telephone 10b or softphone 12 Is sent.

At this time, the authentication process in the authentication server 40 may be omitted.

In the case of using a different network, a mobile terminal 16 and a general telephone capable of short transmission / reception through a transmission Internet video telephone 10a, a mobile communication network 24, and a PSTN 22 using the Internet network 20 ( 14) It is a case of transmitting and receiving a short message between.

Sending a short message from the sending Internet video telephone 10a to the SMS server 30, and the SMS server includes a gateway (50, mobile communication SMS gateway or PSTN SMS center gateway) to which the mobile terminal 16 or the general telephone 14 belongs. It is possible to send and receive a short message even when using another network by sending a short message.

3 is a flow chart of a short message service method according to an embodiment of the present invention, and shows a short text transmission / reception process of an internet video telephone period during a video call using the same Internet network.

In this case, since the video call is busy using the same internet network 20, the short message is transmitted and received through the channel of the video call that sends and receives video / audio data without using a separate SMS server 30.

The user inputs a short message to be transmitted by using a user interface (UI) of the transmitting Internet videophone 10a (302).

The short message input from the transmitting Internet video telephone 10a is converted into a message (H.245 / SIP / Proprietary Protocol) format that the Internet network 20 can transmit and receive (304).

The message converted by the transmission Internet videophone 10a is added to the video / audio data and transmitted to the reception Internet videophone 10b via the message transmission / reception channel which is already open (306).

The receiving Internet video telephone 10b receives it and analyzes the short text in the received data (308) and outputs it to the screen (310).

In addition to displaying text messages on the screen, the output can be spoken using the TTS (Transaction Tracking System).

If necessary, the short message may be analyzed and then the transmission result thereof may be transmitted to the transmitting Internet video telephone 10a.

4 is a flowchart of a short message service method according to another embodiment of the present invention, and shows a short text transmission / reception process when the same network is used without a video call.

When not in a call state, the SMS server 30 is used because a channel for transmitting and receiving short messages is not formed.

In detail, the user inputs a short message to be transmitted using the UI (User Interface) of the transmitting Internet videophone 10a (402) and transmits it to the SMS server 30 (404).

The SMS server 30 requests authentication from the authentication server 40 to the terminal that has transmitted the short message, that is, the transmitting Internet video telephone 10a (406), and the authentication server 40 to the transmitting Internet video telephone 10a. After the authentication is performed (408), the received short message is stored in the database of the SMS server 30.

The authentication process 406 and 408 through the authentication server 40 can be omitted.

After the authentication process is completed, the SMS server 30 transmits the transmission result message to the transmitting Internet video telephone 10a and transmits a short message to the receiving Internet video telephone 10b or the smartphone 12 that receives the short message. Transmit (412).

The received Internet videophone or smart phone transmits the transmission result message to the SMS server 30 (414) and outputs the received short message on the screen (416).

In addition to displaying text messages on the screen, the output can be spoken using the TTS (Transaction Tracking System).

The transmission 414 of the transmission result message to the transmission internet videophone 10a can be omitted.

FIG. 5 is a flowchart illustrating a short message service method according to another embodiment of the present invention, and illustrates a short message transmission / reception process when a receiving side uses a different network from the Internet without a video call.

When not in a call state, the SMS server 30 is used because a channel for transmitting and receiving short messages is not formed.

In the case of using a different network, the process of transmitting a short message to the SMS server 30 and authenticating the transmitting Internet videophone 10a is the same as that of FIG. 4.

However, since different networks are used, a medium for mediating a short message is required. The gateway 50 plays a role.

The gateway 50 becomes a mobile communication SMS gateway when the short message is received by the mobile terminal 16, and becomes a PSMSC (PSTN SMS Center) gateway when the short message is received by the general telephone 14.

When the SMS server 30 transmits the short message sent from the transmission Internet video telephone 10a to the gateway 50, the gateway 50 after the authentication process for the mobile terminal 16 or the general telephone 14 is finished. The short message transmitted to 50 is transmitted to the mobile terminal 16 or the general telephone 14.

In detail, the user inputs a short message to be transmitted using the UI (User Interface) of the transmitting Internet videophone 10a (502) and transmits it to the SMS server 30 (504).

The SMS server 30 requests authentication from the authentication server 40 to the terminal that has transmitted the short message, that is, the transmitting Internet video telephone 10a (506), and the authentication server 40 to the transmitting Internet video telephone 10a. After the authentication is performed 508, the received short message is stored in the database of the SMS server 30.

The authentication process (506,508) through the authentication server 40 can be omitted.

After the authentication process is completed, the SMS server 30 transmits the transmission result message to the transmitting Internet video telephone 10a and transmits a short message to the gateway 50 of the network to which the mobile terminal or the general telephone of the receiving side belongs. (512).

The gateway 50 authenticates the mobile terminal 16 or the general telephone 14 on the receiving side and transmits the short message to the mobile terminal or the general telephone on the receiving side (514).

Upon receiving the short message, the mobile terminal 16 or the general telephone 14 transmits the transmission result message to the gateway 50 (516) and the gateway 50 again to the SMS server 30 (518).

The transmission result message transmission process (516, 518) can be omitted.

The general telephone 14 or the mobile terminal 16 outputs the received short message on the screen (520).

In addition to displaying text messages on the screen, the output can be spoken using the TTS (Transaction Tracking System).

According to the present invention, the short message service system of the Internet video telephone can implement various text communication functions such as message communication and short message service using text in addition to the existing video / audio without a separate external service.

In addition, taking advantage of the video phone based on digital data communication, it is possible to send and receive various text messages, digital video calls, and real-time text messages, ranging from Korean, English, numbers, and various special symbols that cannot be realized in existing analog phones. The chat function, the storage of text data, and the implementation of a short message service using the same can be immediately implemented in the Internet network.

The present invention can provide more convenience to the disabled as well as the general user.

For example, a deaf person makes a video call with sign language, but if the other person does not know the sign language or the same deaf person has a lot of inconvenience in the call when the video is not clear.

In this case, using a simple text message function instead of a sign language can give a convenience of communication than a conventional video call only method.

Technically, various additional applications such as message transmission and reception and data exchange are possible with an Internet video telephone connected to an internet network and a short message service (SMS) of a digital mobile terminal or an instant messaging service of a PC.
