Description

Method for providing Internet chat service linked to mobile terminal {Method to provide Internet chatting service linked with portable phones}

The present invention relates to a method for providing an internet chat service in connection with a mobile terminal. In particular, in a chat service system that provides a chat service in a 3D virtual space on the Internet, information on whether a chat counterpart currently accesses a chat room is transmitted to a subscriber's mobile terminal. The present invention relates to a method of providing a chat service through a method of individually transmitting and receiving text messages between a mobile terminal and computer terminals of a plurality of other subscribers currently connected to a chat room.

Currently, as the Internet becomes a part of daily life, the kinds of services provided through the Internet are becoming very diverse. Among them, the Chatting service system provides a service that allows a large number of users to talk and exchange text messages through a computer in a chat room in a 3D virtual space on the Internet, and communicate with an unknown person through a computer. Due to its interest, it is becoming a service system that is commonly used not only for low age groups such as teenagers but also for other age groups.

In order to use such a chat service system, it is common to subscribe to a chat service system that provides a chat service that a user wants to use in a 3D virtual space on the Internet, and a subscriber chats among several subscribers connected to the chat service system. Select the person you want to chat with and then chat with that person. At this time, the computer terminals of users of the chat service are connected to the Internet through modems, telephone lines, or dedicated lines. This time, a publication (booklet) titled 'Computer Network Programming' (Heungneung Science Press; published October 10, 1997) The general chat technique of the related art will be described by quoting the document. In view of the Internet-based client / server type, a subscriber using a chat service corresponds to a client, and a chat service system providing a chat service corresponds to a server. Hereinafter, for convenience of description, a chat service subscriber will be referred to as a 'chat client' and a chat service system will be referred to as a 'chat server'. The chat server processes a request to join a chat from any chat client. The function of broadcasting (delivering) a chat message sent by the chat client participating in the chat to the counterpart, that is, all the chat clients. Meanwhile, the description will be made based on the chat server program (chat_server.c) that uses the parent concurrent server structure. Affiliate Kancarent Server provides multiple clients with a chat service in parallel, but does not replicate the number of clients that process it, so that one process is responsible for communicating with multiple clients. Since the chat client's request to join the chat must be handled and the messages sent by other chat clients must be delivered to all relevant chat clients, I / O changes through the socket must be handled in asynchronous mode. A socket consists of a node address and a port number identifying a service, and refers to an identifier that identifies a specific service on a specific node of a communication network. When any input / output change is detected, the socket join applicant assigned to this socket is processed. . The asynchronous mode is a socket operation mode that returns to a socket-related system call that can be stopped and informs an application program of the result asynchronously after the corresponding operation of the system call is completed. Looking at the function of (chat_client.c), the chat message entered in the chat client's computer terminal is transferred to the chat server according to the TCP / IP communication protocol, or the chat message transmitted from the chat server according to the TCP / IP communication protocol is chatted. Performs a function that outputs to the screen of the client computer terminal. However, as a prerequisite for performing such a function, the chat server program is first executed in the chat server, so that the chat client program needs to know the port number and IP address used by the chat server program. A flowchart illustrating the operation of a chat server using the concurrent server model. First, socket () is called to open a socket (hereinafter referred to as an initial socket) to receive a chat participant, and bind () the socket with its socket address (S10 and S11). Subsequently, select () is called for the initial socket and waits until a socket input / output change occurs (S12). If there is a new chat participant's request and an I / O change occurs in the initial socket, call accept () to handle the chat participant's connection, and register the socket number returned by accept () in the participant list (client_s []). (S13, S14, S15). Next, select () is called again for the newly created socket and initial socket returned to step S12. When receiving a chat message through an existing chat participant instead of the initial socket, all the related chats are received. The participant is transmitted to the participant according to the TCP / IP communication protocol (S13 and S16). FIG. 10 is a conceptual diagram illustrating a connection relationship between a conventional chat server and a chat client, and follows the TCP / IP communication protocol for communication with each other. The chat server receives a new chat participant through the initial socket, and the socket number of newly joined chat clients is managed in client_s []. Since the figure shows four chat participants and one chat applicant, the chat server program (chat_server.c) should call select () to detect input / output changes occurring on five sockets.

However, in the above-described conventional chat service system, when a chat counterpart to whom he / she wishes to chat is not currently connected to the chat room, the other party has no choice but to wait for the other party to connect to the chat room. In addition, due to the nature of the chat room, the other person's personal information is often kept secret, it is not easy to be connected to the chat room in the same time zone as the other party.

In this case, if you terminate the connection with the chat room and do something else, the other party may not know whether the chat room is connected to the chat room. In addition, there is an inconvenience that the chat room users should be tied up in front of the computer because they cannot communicate with each other through the chat room unless they are simultaneously connected to the chat room.

Accordingly, the present invention has been made to solve the above problems, by linking the mobile terminal that is currently widely distributed to the chat service system via the Internet to the subscriber's mobile terminal information on whether the chat partner is currently connected to the chat room. An object of the present invention is to provide a method of providing a chat service by transmitting or receiving a text message between a mobile terminal of a subscriber and a computer terminal of a plurality of other subscribers currently connected to a chat room.

In order to achieve the above object, a method of providing an internet chat service in connection with a mobile terminal according to the present invention includes a subscriber subscribed to a chat service system providing the chat service, among chat counterpart information provided by the chat service system. A counterpart selection step of selecting a chat counterpart to be desired; The chat service system allows the subscriber and the chat counterpart to perform a chat when the chat counterpart selected in the counterpart selection step is currently accessing a chat room of the chat service system. Waiting for a counterpart connection to determine whether a chat counterpart accesses the chat room; The chat service system, if it is determined that the chat counterpart is connected to the chat room in the waiting step for the counterpart connection, a message indicating that the chat counterpart is connected to the corresponding phone number of the connected chat counterpart among the unique phone numbers assigned to each chat counterpart. Access information transmission step of transmitting to the subscriber's mobile terminal through a mobile communication system; A response message transmitting step of transmitting a response message to a unique telephone number of a chat counterpart received with the message by the subscriber who has received the message; A response message reception step of receiving, by the chat service system, a response message transmitted by the subscriber in the response message transmission step through a mobile communication system; And the chat service system is configured to include a response message delivery step for transmitting the response message received in the response message receiving step via the Internet to the computer terminal of the chat counterpart assigned to the unique phone number on which the response message is carried; It is done.

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

1 is a configuration diagram of a system for providing a service according to the present invention, a chat service system for providing a chat service according to the present invention to subscribers through a three-dimensional virtual space of the Internet 200, for example, an Internet server 300. ), A short message service (Short Message Service Server: 410) to exchange a short message (Short Massage) with the Internet server 300, the short message received from the SMS server 410 to the base station (430) or performs the reverse function The mobile communication switch 420, and the base station 430 to wirelessly propagate the message to the mobile terminal 500 or performs the reverse function.

Here, the subject providing the chat service according to the present invention is the Internet server 300. Hereinafter, the subject of the service performing the present invention will be referred to as an "Internet server" in order to help understand the description in terms of hardware. In the description of the Internet service, it is referred to as a "chat service system". In addition, the network model basically used in the present invention takes a client / server structure based on the Internet, that is, the World Wide Web (WWW), subscribers and chat counterparts correspond to clients, and Internet servers and chat service systems. The back is the structure corresponding to the server. In the meantime, detailed descriptions of basic items such as a user or subscriber access standby, connection determination, and client requirement processing will be omitted in the server program.

The SMS server 410, the mobile communication switch 420, and the base station 430 are components of the mobile communication system 400 for providing a mobile communication service. In order to implement the present invention, an association with a mobile communication service provider is required. Can be.

Through such a system, the Internet server 300 can send a message to the subscriber's mobile terminal 500 through the mobile communication system 400 and vice versa to receive a message sent from the mobile terminal 500. .

2 is a flowchart of a first embodiment according to the present invention. If a subscriber who has subscribed to a chat service system for providing a chat service according to the present invention sets a chat counterpart to chat, the chat service system is a chat room. An embodiment of a procedure (hereinafter referred to as a chat counterpart connection status notification procedure) of informing the subscriber's mobile terminal 500 through the mobile communication system 400 when accessing the terminal is illustrated.

First, the subscriber selects a chat counterpart who wants to chat among chat counterpart information provided by the chat service system. The selection information is transmitted to the chat service system via the Internet 200 (S210).

The chat service system determines whether the chat counterpart selected in step S210 is currently connected to the chat room (S220), and if the chat counterpart is currently connected to the chat room, the subscriber and the chat counterpart perform a chat (S230). If it is not connected to the chat room, it is determined whether the chat counterpart is connected to the chat room in the standby state (S240). In general, the Internet server 300 waits until an input / output (I / O) change occurs in the sockets while the sockets for accepting the chat participant remain open. The I / O change on the socket is what happens when the chat participant sends a connection request.

If it is determined that the chat counterpart is connected to the chat room during the waiting for access in step S240, the chat service system transmits a message indicating this to the subscriber's mobile terminal 500 through the mobile communication system 400 (S250).

3 is a diagram illustrating a process of a first embodiment according to the present invention, and the chat partner connection state notification procedure illustrated in FIG.

First, the subscriber should select the desired chat partner, which is preferably done through the chat partner setting screen transmitted from the chat service system. FIG. 4 shows an example of the chat partner setting screen.

In the screen shown in FIG. 4, a space for displaying the ID of the selected chat partner, a space for outputting detailed information of the selected chat partner, and a switch for deciding whether to receive a service according to the present invention (for example, indicated by “a blank ID”) On / Off display part indicating the current setting status of this switch, a space for inputting a mobile phone number to receive a message indicating that the chat partner is connected, and a chat partner ID to which the chat partner is additionally registered or selected. A switch for deleting the ID is shown.

The subscriber enters a phone number (eg, 019-300-9436) of the mobile terminal to be contacted by using this screen, and selects and registers a chat counterpart. In FIG. 4, a subscriber registers a chat counterpart "AAA", "BBB", and "CCC" and selects "AAA" and "CCC" among them. Of course, the registered chat counterparts ("AAA", "BBB", "CCC") are also subscribers of the chat service system, but for convenience of description is divided into "subscriber" and "chat counterpart".

When the subscriber completes the setting, the information set on the screen is transmitted to the Internet server 300 through the Internet 200. Now, the subscriber can terminate the connection and leave the computer for personal use.

Now, the chat service system determines whether the chat counterpart selected in step S210 is currently connected to its chat room, and if the chat counterpart is not currently connected to the chat room, the chat counterpart is connected to the chat room from the I / O change of the socket of the server program in the standby state. It is determined whether or not a connection is made.

If a chat party ("AAA", "CCC") that was not connected is determined to be connected to a chat room at some point, a short message indicating that the chat party is connected (eg "AAA is connected") Is transmitted to the mobile communication system 400 together with the telephone number of the mobile terminal 500 of the subscriber, and the mobile communication system 400 transmits the short message to the SMS server 410, the mobile communication system 420, and the base station ( It transmits to the mobile terminal 500 of the subscriber through 430-1,430-2.

Then, a message appears on the mobile terminal screen 510 of the subscriber, so that the subscriber can know that the other party is connected to the chat room, so that the user can enjoy the chat with the other party by using the computer terminal. That is, you do not have to wait for the other party to connect to the chat room.

However, if only such a service is provided, even if the subscriber is not currently able to access the chat room, even if he / she knows that the chat counterpart is connected to the chat room, it is not able to cope with it appropriately. Therefore, the subscriber can send a response message to the chat counterpart using his mobile terminal 500, and in the chat service system, the subscriber's response is transmitted from the mobile terminal 500 of the subscriber through the mobile communication system 400. It may be more preferable if the message is further configured to include a response procedure that receives the message and delivers it to the corresponding chat counterpart. This response procedure will be described in more detail later with reference to FIGS. 5 and 6.

On the other hand, in the chat service system, if there are a plurality of chat counterparts set by the subscriber, a plurality of messages transmitted and received between the chat service system and the subscriber are included in the message using a predetermined identifier, in this case, a unique telephone number, to each chat counterpart. It is more preferable to divide according to each other so that a plurality of chat counterparts can be individually managed.

In order to implement such a function, the chat service system may use a method of individually assigning a unique phone number to each of a plurality of chat counterparts connected to their chat room. In order to use this method, it may be desirable to set unique phone numbers with the mobile operator in advance.

In addition, the chat service system transmits a unique phone number assigned to the chat counterpart to the subscriber's mobile terminal 500 together with a message indicating that the chat counterpart is connected to the chat service system.

As an example, if a unique telephone number "019-300-1111" is assigned to the chat partner "AAA" and a unique telephone number "019-300-3333" is assigned to the chat partner "CCC", The terminal screen 510 may be displayed as shown in FIG. 3. That is, the message related to the chat partner "AAA" is displayed with the unique telephone number "019-300-1111", and the message related to the chat partner "CCC" is displayed together with the unique telephone number "019-300-3333". do.

FIG. 5 is a flowchart of a second embodiment according to the present invention, and an embodiment of performing a response procedure will be described with reference to the flowchart.

First, a subscriber who receives a short message sent from a chat service system through his mobile terminal 500 responds to a unique phone number of the corresponding chat partner received with the short message using his mobile terminal 500. Transmit (S510). Then, the chat service system receives the response short message transmitted by the subscriber in step S510 through the mobile communication system 400 (S520).

Subsequently, the chat service system transmits the response short message received in step S520 to the computer terminal of the chat counterpart assigned to the unique telephone number on which the response short message was carried through the Internet 200 according to the TCP / IP communication protocol (S530). ), The response short message delivered to the computer terminal screen of the chat partner is automatically output. Specific chat techniques between the chat service system and the computer terminal of the chat counterpart will be referred to the contents described in the above-described prior art.

FIG. 6 is a diagram illustrating a process in which a second embodiment proceeds according to the present invention, and in detail, the response procedure illustrated in FIG.

Receiving a message that the chat partner "AAA" and "CCC" that the subscriber has set up has connected to the chat room, the subscriber uses the mobile terminal 500 to the unique telephone number 019-300-1111 included in the message. "Send a response message (e.g.," let's chat at 9 pm ") to send to, and send a response message to" CCC "with a unique phone number of 019-300-3333 (e.g.," Meet at 9 pm in Sinchon " ).

The response messages are transmitted to the mobile communication switch 420 through the base stations 430-1 and 430-2, and again to the Internet server 300 via the SMS server 410.

Then, the Internet server 300 transmits the corresponding response message through the Internet 200 to the computer terminals 110 and 120 of the chat counterpart, which are assigned to the unique telephone number on which the response message is carried. That is, in the above example, since the message "let's chat at 9 pm" was received at 019-300-1111, the computer terminal 110 of the chat counterpart "AAA" which assigned the unique telephone number 019-300-1111 was sent. Since the message "Let's meet at 9 o'clock in Sinchon" was transmitted through the Internet 200, 019-300-3333, the computer terminal of the chat counterpart "CCC" that assigned a unique telephone number 019-300-3333 ( 120 through the Internet (200).

As an example, if the subscriber who sent the message is "Omniman," the message "Amn" sent "Omniman" on the computer terminal screen. You will see a message like this. In addition, on the computer terminal screen of the chat partner "CCC", "Omniman sent a" Let's meet at 9 o'clock in Sinchon "message." You will see a message like this.

On the other hand, another embodiment for preferably performing a chat service through the Internet is a first subscriber to the chat service system to send a message to the other party (second subscriber) to the chat service system via the Internet (200) When transmitting, the chat service system transmits the message to the mobile terminal 500 of the second subscriber through the mobile communication system 400 when the second subscriber is not currently connected to the chat room of the chat service system. will be. In other words, it refers to a service that allows messages to be exchanged between computer terminals and mobile terminals of subscribers currently connected to a chat room.

In this case, since there may be a plurality of first subscribers who send a message, it is preferable to divide the messages transmitted and received by each subscriber for each subscriber so as to manage the plurality of messages individually. In addition, in order to realize such a function, as in the chat partner connection status notification procedure, a method of assigning a unique telephone number to each subscriber transmitting a message may be used.

The chat service system transmits a unique telephone number assigned to the subscriber who transmits the message when the message is transmitted to the mobile terminal of the second subscriber.

In order to use such a message transmission procedure, a first subscriber who wants to transmit a message must first prepare a message to be transmitted and send it to a chat service system that performs a chat service according to the present invention. Note that it is desirable to be performed on the message input screen.

7 illustrates an example of a message input screen provided by a chat service system, and may include a window for inputting an ID of a counterpart to transmit a message, a window for inputting message contents, and a send button. .

That is, when a first subscriber who wants to send a message enters a second subscriber's ID in an ID input window, enters a message body in a window for inputting a message, and presses a send button, a chat service is performed from a computer terminal of the first subscriber. The message is sent via the Internet 200 to the system. Then, the chat service system transmits a message to the second subscriber having the corresponding ID. If the second subscriber is not currently connected to the chat room, the chat service system sends the message to the mobile terminal of the second subscriber.

8 is a diagram illustrating a process of a third embodiment according to the present invention, and a process of transmitting a message will be described in detail with reference to this.

First, subscribers "AAA" and "CCC" who want to send a message write a message to be sent using their computer terminals 110 and 120. In this case, as shown in FIG. 7, a message input screen sent by the chat service system may be used, and when a send button is pressed, a written message is transmitted to the Internet server 300 through the Internet 200. That is, the subscriber "AAA" transmits the message "Let's meet at 6 pm", and the subscriber "CCC" transmits the message "Let us meet".

The Internet server 300 determines whether the second subscriber to receive the message is currently connected to the chat service system, and transmits the message to the mobile terminal of the second subscriber and the message if the second subscriber is not currently connected. A unique telephone number assigned to a first subscriber is transmitted to the mobile communication system 400. Then, the message is transmitted to the mobile terminal 500 of the second subscriber via the SMS server 410, the mobile communication switch 420, and the base stations 430-1 and 430-2.

Now, a unique telephone number and a corresponding message appear on the mobile terminal screen 510 of the second subscriber. Of course, in addition to the message sent by the subscribers "AAA" and "CCC" from the Internet server 300, it can be a more preferable practice to send additional content, such as "AAA message", "CCC message" content.

Meanwhile, an embodiment of performing a message response procedure in which a response message is transmitted from the mobile terminal 500 of the second subscriber to the computer terminals 110 and 120 of the first subscriber will be described with reference to FIG. 6.

Receiving messages sent by the first subscribers "AAA" and "CCC", the second subscriber uses a mobile terminal 500 to send a response message to "AAA" with a unique telephone number of 019-300-1111 (for example, "PM"). "Let's chat at 9 o'clock"), and also send a message to "CCC" (e.g., "Let's meet at 9 o'clock in Sinchon") to the unique phone number 019-300-3333.

The message transmitted by the second subscriber using its mobile terminal 500 is received at the base stations 430-1, 430-2 and sent to the Internet server 300 via the mobile communication switch 420 and the SMS server 410. Is received.

Since the Internet server 300 receives the message "Let's chat at 9 pm" in the above example as 019-300-1111, the computer terminal of subscriber "AAA" which assigned a unique telephone number of 019-300-1111 ( 110), but the message "Let's meet at 9 o'clock in Sinchon" was received at 019-300-3333, so the computer of subscriber "CCC" assigned a unique telephone number of 019-300-3333. The terminal 120 transmits the data through the Internet 200.

In this way, messages can be sent and received individually between the computer terminal and the mobile terminal of subscribers connected to the chat room.

Of course, if you provide such services together, it is possible to more preferably provide an Internet chat service.

According to the present invention, it is possible to know a situation in which a chat counterpart accesses a chat room through a mobile terminal, so there is no need to wait until the other party accesses the chat room in front of the computer, and to send a message to the other party who is connected to the chat room through the mobile terminal. Since it can be received, the convenience of the user of the chat service is greatly improved.

In addition, since the chat service is advanced to attract more subscribers, the profitability of the chat service provider is increased.
