The present invention relates to an instant messaging between a mobile phone and a mobile phone or between a mobile phone and a PC. In particular, the present invention does not require a subscription to a sizing service and does not require registering a party to be invited to a friend list. The present invention relates to a method and a system for enabling instant messaging on a mobile by inviting the other party using only a number.

Due to the popular short message service (SMS) in the mobile communication field using a mobile phone, it is becoming a new trend to communicate with each other using short messages rather than voice calls. However, short messages can be delayed if the queue is long, and each time a message is sent, the mobile phone number of the other party must be entered. There is a disadvantage that does not guarantee receiving. In addition, the user interface may be uncomfortable because the user interface for providing a short message to the mobile phone and the execution process of the transmission and reception vary depending on the mobile phone manufacturer.

Instant messenger services that can send and receive messages between PCs via wired Internet are also widely used. This instant messenger has the advantage of being able to send and receive chat messages in real time once the conversation starts. In recent years, such an instant messenger has been extended to be used on a mobile phone. With the service, a chat inviteer can send a message in real time to the other party in the PC environment or the other party using the other mobile phone. I can receive it.

However, in order to use the instant messenger service, some conditions must be satisfied. First, you (the inviter) and the other party, who are the parties to the conversation, must be registered together in a particular instant messaging system. Therefore, you must subscribe to the messaging service. Furthermore, membership alone is not enough, and the person who wants to talk should register as his or her friend. You must meet these conditions before you can communicate with the invitee. Therefore, the general mobile phone users can not send and receive messages in real time with the other party who does not subscribe to the instant messaging system or is not registered as a friend. Therefore, the shortcomings of the short message service and the instant messaging service need to be compensated and a more convenient instant messaging service that takes advantage of both services is needed.

The present invention does not require a chat inviter or the other party to register and register the friend as a friend, the mobile phone number of the inviter wants to chat anytime and anywhere conveniently in the conversation by instant messaging between mobile phones To provide a service method that enables the service.

In addition, the present invention provides a variety of different types of conversation methods, such as a method of using a short message method and an instant messaging method, and an instant messaging method between a mobile phone and a personal computer (PC), in addition to the instant messaging method between mobile phones. The object of the present invention is to provide a mobile phone-based instant messaging service that users can select according to their needs.

In order to achieve the object of the present invention as described above, the present invention provides a mobile telephone number based Mobile Instant Messaging that compensates for the shortcomings caused by short messages and instant messengers when sending and receiving messages in a mobile phone. Propose a service method (PMIM).

According to an aspect of the present invention, a method for providing a message communication service between a user 1 of a first mobile phone and a user 2 of a second mobile phone by using an instant messaging service system interworking with the wireless Internet, wherein the user 1 is provided with the first message. 1 executing a client program for instant messaging on the mobile phone and transmitting the number of the second mobile phone of the user 2 inputted for the conversation request to the service system; The service system establishes a chat room in response to the chat request, sockets the session of the first mobile phone to the chat room, and transmits a message to the user 2 indicating that the chat request has been received to the number of the second mobile phone. ; If the user 2 executes the client program for instant messaging on the second mobile phone and accesses the service system to respond to the chat request, the service system providing the chat room information to the second mobile phone; And connecting the session of the second mobile phone to the chat room when the user 2 enters the chat room, wherein the first and second users are connected to the first and second mobile phones through the chat room. Provided is a mobile number based mobile instant messaging service method, which is connected to send and receive instant messages using respective mobile phones.

In the instant messaging service method, the message transmitted to the second mobile phone to inform the user 2 that a conversation request has been received is characterized in that the short message provided by a short message service (SMS). Further, the short message transmitted to the second mobile phone is characterized in that the short message in the form of a URL callback containing the URL (URL) information to download the client program for instant messaging.

In the instant messaging service method, preferably, either one of the user 1 and the user 2 inputs a cell phone number of the user 3 and a conversation request from the user's mobile phone during instant messaging, and transmits a conversation invitation message to the service system. If so, the service system may further include a step of delivering the conversation invitation message to the mobile phone of the user 3 so that the user 3 may be invited to the chat room to have a multi-party conversation.

Preferably, the instant messaging service method, when a user who is talking in the chat room changes his mobile phone to a mobile state, the client program terminates in the mobile phone, but the service system maintains the session of the mobile phone of the user. The communication between the user who has changed to the mobile state and the rest of the user of the chat room may be provided with a short message and an instant message.

Furthermore, the instant messaging service method may further include storing the contents of the conversations exchanged in the chat room in a database of the service system and providing the stored conversation contents in response to a user's request.

Furthermore, in the instant messaging service method, the socket connection between the mobile phones participating in the chat room is made by associating a chat room ID assigned to the chat room by the service system and a mobile phone number participating in the chat room.

Meanwhile, the present invention enables not only instant messaging between mobile phones but also instant messaging between mobile phones and PCs. To this end, the instant messaging service method is executed when the other party requesting a conversation runs on a personal computer (PC) connected to the Internet and accesses the service system by issuing an authentication key for the mobile phone number of the user. If the user provides the user's mobile phone, and the user reconnects to the service system with the personal computer and inputs the issued authentication key, the service system regards the chat room list in which the user is invited as the authenticated user and invites the user to the PC. In addition, the PC-to-mobile instant messaging is also possible.

The client program is an embedded program installed as a basic program on the first mobile phone or the second mobile phone, or a program that is downloaded to the first mobile phone or the second mobile phone or the PC from the service system.

According to the present invention as described above, PMIM service users, if they know only the mobile phone number of the other party, can use the mobile phone number to proceed with the conversation, such as inviting the other party to the conversation in real time. If the client program for the PMIM service is installed as the built-in software of the user's mobile phone, there is a convenience that can be used without installing a separate client program like a short message. In addition, if it is not installed as the embedded software, the short message requesting the conversation is provided to the conversation respondent by including a URL where the client program can be downloaded. The Respondent can access a specific site using the URL provided by his mobile phone, download a client program from the site, install it on his mobile phone, and then participate in the conversation. In addition, it is not always necessary to connect to the server through the client program, it is possible to change the state of its own to the mobile state as necessary to receive a message coming to it as a short message. Also, when replying through short message, it is easy to use by diversifying the way of sending and receiving messages, such as processing it on the server and delivering it to the other party.

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

1 schematically illustrates the configuration of an entire system for implementing a PMIM service. In order to enable the PMIM service, a PMIM service system 100 operated by a PMIM service provider, for example, a wireless mobile communication system 200 of a mobile communication provider, and a user's mobile phone 300 should be provided. The PMIM service system 100 includes a PMIM server unit 110 and a database 170, and serves as a server system that provides a PMIM service to a user's mobile phone 300 through a wireless mobile communication system 200. The mobile phone 300 and the PMIM service system 100 are interworked through the SMS unit 210 or the wireless Internet service unit 220 of the wireless mobile communication system 200. The mobile phone 300 should be installed with a client program 310 written to use the PMIM service. The client program 310 may be installed as a basic program at the time of manufacture of the mobile phone. Otherwise, the client program 310 may be downloaded and installed by accessing the wireless mobile communication system 200 or the PMIM service system 100 over the wireless Internet. . In addition, the message transmitted and received by the mobile phone 300 with the PMIM service system 100 is transmitted using a short message service (SMS) or a socket-based wireless Internet service provided by the wireless mobile communication system 200. Therefore, in order to use the PMIM service, the mobile phone 300 must have an SMS function and a wireless Internet function. In the figure, the service subjects of the PMIM service system 100 and the wireless mobile communication system 200 are distinguished from each other, but these two systems 100 and 200 may be operated by the same entity, for example, a mobile communication service provider. The PMIM service system 100 and the wireless mobile communication system 200 may be connected to each other by, for example, the Internet, a dedicated communication line, or a LAN, and the communication method may use, for example, a TCP / IP protocol.

In such a system, the following types of instant conversations are possible:

i) The mobile phone user (inviter) may request a conversation based on the mobile phone number to the desired counterpart through the function provided by the PMIM server unit 130. If the other party responds to the conversation request, the conversation can take place between them. You can also leave a message if the other party does not accept the conversation request.

ii) It is also possible to change the means of communication from a mobile phone to a PC and perform instant messaging in a phone-to-PC manner.

iii) In addition, one of the parties to the conversation may change the connection state of its PMIM service system 100 from the online state to the mobile state so that the conversation can be made through a mobile phone call with a third party. It is also possible.

iv) Furthermore, it is also possible to invite another party to participate in the conversation during the instant conversation.

v) It is also possible for a person to participate in several chat rooms.

FIG. 2 shows an exemplary configuration of a PMIM service system 100 suitable for providing a PMIM service based on the schematic diagram of the overall system of FIG. In the PMIM service system 100, the PMIM server unit 110 includes a mobile gateway 120 and a PMIM server 130. In the figure, client A 300a is the conversation inviteer's mobile phone, and client B 300b represents the invitee's mobile phone.

The mobile gateway 120 is a part that is in charge of communication with mobile clients (ie, mobile phones) 300 (300a, 300b). Specifically, the mobile gateway 120 actually communicates directly with the wireless mobile communication system 200 and communicates with the mobile clients 300 through the wireless Internet service 210 of the mobile communication system 200. A connection manager 122 and a session manager 124. The connection manager 122 is a module that manages such a connection in the socket layer when the clients 300a and 300b have connected to the PMIM service system 100 through the wireless Internet service unit 210 of the wireless mobile communication system 200. to be. The session manager 124 is a module that exchanges messages with the clients 300a and 300b through wireless Internet communication. In particular, the session manager 124 determines a state of the clients 300a and 300b connected to the PMIM server 130 in a manner suitable for that. This module sends and receives messages over the wireless Internet. In the PMIM service system 100, the states of the clients 300a and 300b are classified into four types: an online state, an offline state, a mobile state (mobile state transition), and an internet state (state connected to a PC). The online state is a state in which the client is connected to the PMIM server 130, and the offline state is a state in which the connection is released. The mobile state is a state in which a client (eg 300a) is not connected to the PMIM server 130 through a socket connection, and receives a message from the counterpart client (eg 300b) through the SMS gateway 140 as a short message. . The Internet status is not a user using a mobile phone as a client, but a computer (PC) -based messaging is possible where a wired Internet is available nearby. The session manager 124 automatically grasps these various types of client statuses to determine what type of message to send, and allows the message to be sent according to the identified status.

The PMIM server unit 130 is a module interworking with the database (DB) 170 and internally includes a chat manager module 132, a registrar module 134, and an SMS module 136. .

The chat room manager 132 is a module that opens and manages a chat room and processes messages exchanged in the chat room. At this time, the chat room manager 132 has a function of temporarily storing the chat of the chat room. Therefore, even if the user changes the state of the client and ends the client program and then joins the chat room again, the user can optionally check the chat message. Messages sent and received in chat rooms can be managed, for example, by a tree structure file system or by using a database. When the chat room is finally terminated, the chat room message may be deleted or stored in the database 170.

The registration unit 134 is a module that manages user information. When a specific person logs in to the PMIM server 130, the registration unit 134 records login information of the client in the database 170 and reads the client information from the database 170 as necessary. Serve

The SMS unit 136 generates an SMS message, converts an instant message received from the chat room manager 132 into an SMS message, or vice versa, converts an SMS message into an instant message and provides the chat room manager 132 to the chat room manager 132. Module. The SMS generated by the SMS unit 136 is delivered to the client through the SMS gateway 140.

The database unit 170 stores a message data unit 172, which is a space for storing messages sent and received in a chat room, a chat room data unit 714 for storing and managing information on an established chat room, and a client program for PMIM. The server 150 includes a PMIM program unit 176 for downloading the program data to the client.

The PMIM service system 100 may further include an SMS gateway 140. The SMS gateway 140 interworks with the SMS unit 220 of the wireless mobile communication system 200 to exchange short messages.

In addition, the PMIM service system 100 may further include a content server 150. The content server 150 separately prepares a client program for PMIM for each platform of a mobile communication company, and has a client program for a mobile phone, a PMIM client program for a personal computer, and automatically selects and provides a program suitable for a client device. do. As mentioned above, in order to use the PMIM service, a client program must be installed in the mobile phone. There may be a mobile phone that does not have the client program basically installed in the mobile phone manufacturing. The content server 150 has a client program to be provided to such a mobile phone, and if the client mobile phone connected to the PMIM service system 100 holds the program, and if it does not have the program, the content server 150 holds the program. Will be automatically downloaded and installed on the client's phone. If the client program is adopted as the basic software of the mobile terminal and embedded in the mobile phone, the content server 150 does not have to download it.

Furthermore, the PMIM service system 100 may further include a provisioning server 160. The server 160 is equipped with a user management module 162 and a system monitor module 164 to monitor and appropriately manage the status of the other servers of the PMIM service system 100 and the connection amount to each server. Do it.

The PMIM service system 100 has such a configuration and provides various additional services including providing an instant messaging service between mobile phones through a mobile phone number. 3 and 4 are for explaining the overall concept of this instant messaging service, the user 1 (invitee) requests a conversation to the mobile phone (client B) of the user 2 (party) using his mobile phone (client A) It is a flowchart which shows the case.

3 and 4, when Client A, the user's mobile phone, accesses the PMIM service system 100, the PMIM service system 100 determines whether the client program for PMIM is installed on the client A, and then PMIM. If the client program is not installed, it is automatically downloaded and installed on the client A (S10 to S14). To this end, the user 1 may be a system for providing a PMIM client program using the client A (which may be basically a content server 150 of the PMIM service system, and may use the same server in a wireless mobile communication system). You will be able to download and install the program. Then, when the user 1 requests the conversation by inputting the mobile phone number of the person who wants to invite to the client A, the PMIM service system 100 transmits the conversation request short message to the corresponding mobile phone (client B) (S16). The user 2 who has received this short message also accesses the PMIM service system 100 using the client B (S26, S28). The PMIM service system 100 similarly checks whether the client program for PMIM is installed on the client B, and if not installed, the PMIM service system 100 downloads and installs the client program for PMIM (S30 and S32). After this process, the client B confirms a conversation request for itself (S34). If the user 2 approves the conversation request, the approval message is sent to the user 1 through the PMIM service system 100 (S36 and S38). When a message of approval of a message arrives on the user's mobile phone, the user can perform socket-based instant messaging through the PMIM service (S18 and S20). If the user 2 refuses to approve the conversation, the user 1 can leave a simple message to the user 2 through the message service (S24). Afterwards, when the user 2 connects again, the messages may be selectively checked (S42). If the client program for PMIM is embedded as basic application software at the time of manufacture of the mobile phone, the procedure (S10 to S14, S28 to S32) for connecting to the PMIM service system 100, downloading and installing the program is omitted. Can be.

The following is a description of the protocol used in the actual PMIM, the list of protocols used when the client logs in to the PMIM service system 100 is shown in Table 1 below. 'Server' refers to the PMIM service system 100.

TABLE 1

Command From Receiver (To) Description PID Client server Send your own mobile number PIDPC                                          Client (PC) server Send your own mobile number and authentication key                                          ANS server Client Send 'OK' when the connection confirmation message is normal, and send 'REQ' when there is a chat room that invited you MLIST server Client My chat room list ILIST server Client List of chat rooms that invited you STATUS Client server Change the state of the client. NICK Client server Set or change an alias. On initial connection, the nickname is sent, and when it is changed, it is sent to the people who are currently in the chat room. NICK server Client Sent when changing the PID name of the PID

5 shows a procedure for a user to access the PMIM service system 100 by executing a client program for PMIM on his mobile phone. When the mobile phone user 1 (invitee) first logs into the PMIM service system 100 to communicate with the mobile phone user 2 (the other party) in the PMIM manner, the mobile phone user ID (PID, that is, the mobile phone number) is transmitted to the server. . At this time, when the user 1 does not directly input his PID, but the PMIM client program is executed in his mobile phone (client A), the user 1 is automatically transmitted to the mobile gateway 120 of the PMIM service system 100. The PID information is transmitted to the registration unit 134 of the PMIM server 130 to register that the client A is logged in, and at the same time, whether there is a chat room opened by the client A or a chat room opened by another person to invite him or her. It is also sent to the chat room manager 132 for searching. The chat room manager 132 first informs the client A of the search result for the chat room through the mobile gateway 120. If there is no searched chat room and connection is established normally, 'OK' is sent. If there is a searched chat room, 'REQ' message is sent to initialize the list of chat rooms in client A. Then, the chat room manager 132 provides the searched chat room list to the client A through the mobile gateway 120. The user can check the list of searched chat rooms on the screen by executing the 'view chat room list' button of a toolbar, which will be described later.

Extending the functionality further for the convenience of the user, the present invention may allow any one of the conversation parties to perform a so-called PC-to-Phone instant messaging using a PC. Specifically, since the PMIM service will be provided for a fee, it is more economical for a user to use a personal computer (PC) than a mobile phone which has to pay per packet. Therefore, the user is also provided with the ability to access the PMIM service system 100 using the PC if a wired Internet environment is provided in the vicinity. For this purpose, a PC PMIM client program having the same function as the PMIM client program for a mobile phone must be installed. Run the PMIM client program on your PC to enable instant messaging between your PC and your mobile phone.

However, the user who uses a mobile phone may be identified by his mobile phone number, but the identity of the user who uses the PC client may be unclear. Therefore, it is necessary to take a separate proper authentication procedure so that the other party can verify the identity of the person who uses the PC client. desirable. 6 shows an authentication procedure for the user of the PC client 300-2 in this regard. Authentication can be done using the PC user's mobile phone number. When the PC client 300-2 connects to the PMIM service system 100, the PC client 300-2 provides the registration unit 134 through the mobile gateway 120 with information (PIDPC) indicating login from the PC. . This PIDPC is information that does not contain an authentication key. The registration unit 134 checks whether there is authentication key information in the PIDPC, and if it is determined that there is no authentication key, causes the PC user to input his mobile phone number, and then issues an authentication key for the mobile phone number to manage the session management unit 124. ) To be delivered as a text message to the PC client's mobile phone. That is, when the user using the PC client 300-2 is not authenticated in the PMIM service system 100, the PMIM service system 100 sends a text message including the corresponding authentication key to the phone number of the user. To send.

As illustrated in FIG. 7, the user inputs an authentication key (KEY) received from his mobile phone for user authentication in the PC client 300-2. The login information (PIDPC | KEY) including the authentication key is transferred from the PC client 300-2 to the registration unit 134 through the mobile gateway 120 of the PMIM service system 100, and the state registration is performed. Authentication is completed. With this authentication, the PC client user can use the PC to send and receive instant messages with the other party using the mobile phone in the same way as the mobile phone. When a PC client is used to access the PMIM server, the authentication process is performed such that only the owner of the telephone number is authorized to use the PMIM. The procedure after the authentication procedure is the same as that of using PMIM using a mobile phone (see FIG. 7).

 Until now, only a process of connecting a client to the PMIM service system 100 for the first time has been described. The following is an explanation of how to invite a party to a conversation using a mobile phone number. Table 2 below shows the protocol used when User 1 (invitee) calls User 2 (the other party) and talks with him.

TABLE 2

Command From Receiver (To) Description INVITE Client server Invite the user of the mobile number. (Including request message) If you do not open a room, you get a Room ID (the assigned room number for the conversation). INVITE server Client Receive a PID and a nickname from the server. RID server Client Get Room ID from server IN server Client Sent when entering a chat room. OUT Client server If you leave the chat room, send Room ID. OUT server Client When leaving the chat room, the Room ID and PID are sent. MSG Client server Forward a message to that chat room. MSG server Client Forward messages from the server.

Consider a case where a user (inviter) who wants to instant messaging with a mobile phone requests a conversation to another user (the other party) after logging in to the PMIM service system 100. 8 illustrates a process in which the inviter's mobile phone (client A) calls the other party's mobile phone (client B), and FIG. 9 shows various screens displayed on the display of the client A in the process. While the client A 300a logs in to the PMIM service system 100, the screen shown in FIG. 9A is displayed on the client A 300a. When the login procedure is completed, the conversation request is performed as shown in FIG. 9B. It is converted into a screen that can be done. The dialog request screen provides an input box for inputting a mobile phone number of a counterpart to make a conversation request, contents of a conversation request, and a screen name (nickname) of a conversation requester. When the user 1 enters the corresponding content on this screen and presses a specific button (for example, a call button or an OK button) of the mobile phone, the client A 300a sends the INVITE (PID, MSG) message, which is a conversation request message, to the PMIM service system 100. Send to the mobile gateway (120). Then, the screen of the client A 300a is switched to the screen of FIG. 9C, indicating that the conversation request message has been sent. The conversation invitation message INVITE (PID, MSG) is transmitted to the chat room manager 132 and the session manager 124, respectively. If the chat room is not yet open at the time the inviter has requested a chat, the chat room manager 132 opens a new chat room and transmits the corresponding chat room ID to the client A 300a through the mobile gateway 120. Further, the session manager 124 inquires the registration unit 134 to check whether the other party's mobile phone (client B 300b) is currently logged in to the PMIM service system 100 (ie, online). As a result of the inquiry, if the other party is already connected to the PMIM service system 100, that is, when the online state, it informs that a conversation request has been received by using a general communication protocol message such as Transmission Control Protocol (TCP). On the other hand, if the client B (300b) is currently offline, that is, the other party is not connected to the PMIM service system 100, the session management unit 124 notifies the SMS unit 136 of the fact that the SMS unit 136 generates and sends an invitation message msg containing information that client A 300a invites client B 300b to the conversation and sends it to SMS gateway 140. The SMS gateway 140 sends the message msg to the client B 300b as a short message to indicate that a conversation request has been received. It is SMS that informs the other party that there is a request for conversation because SMS is the most suitable tool among the currently developed tools. Therefore, if a separate dedicated protocol for PMIM is developed, it may be able to inform that there is a conversation request using the protocol.

FIG. 10 shows a procedure in which user 2 invited to a conversation responds to the conversation request of user 1, and FIG. 11 shows a screen displayed on client B 300b in the process. On the screen of Client B 300b of User 2 invited to the conversation, a conversation request message including the telephone number, the name of the conversation requester, and the contents of the conversation request is displayed as illustrated in (a) of FIG. 11. If the PMIM client program is not installed in the mobile phone of the counterpart of the conversation request, instant messaging through the PMIM service system 100 cannot be performed. There is no guarantee that the PMIM client program will always be installed on all mobile phones. In view of this, when the short message is notified to the other party that a conversation request has been received, the short message is preferably provided in a call back URL type including a URL where a PMIM client program can be downloaded. Do. In order to respond to the conversation, the user 2 may execute the 'connect' button on the screen of FIG. If the user's mobile phone does not have a PMIM client program, the procedure for downloading and installing the program on the client 2 is performed. As one method for doing this, the 'connect' button allows the user 2's mobile phone to interwork with call back URL information, which enables the user to automatically access the PMIM service system 100 via the wireless Internet. When the 'connect' button is executed, the user 2's mobile phone (User Agent: UA, which is not yet running in the PMIM client program is displayed as UA) is connected to the content server 150 of the PMIM service system 100 through the wireless Internet. The content server 150 retrieves the PMIM client program from the database 170 and downloads it to the user 2's mobile phone UA for installation. When the client program for PMIM is installed through this process, as shown in FIG. 11 (b), a message indicating that the PMIM conversation request has been received and a 'PMIM execution' button are displayed on the screen. User 2 can join the conversation after confirming the chat room of the person who invited him by executing the 'Run PMIM' button on the screen. Specifically, referring back to FIG. 10, the mobile phone of user 2 who executes the PMIM client program sends PID information to the mobile gateway 120 of the PMIM service system 100. From this point on, the user 2's cellular phone is treated as a client of the PMIM service system 100. The PID of the client B 300b invited to the conversation is transmitted to the register 134 and the chat room manager 132, respectively. The registration unit 134 registers that the client B 300b is brought online. The chat room manager 132 retrieves the chat room ID opened by the client A 300a to communicate with the client B 300b, and delivers the chat room ID to the client B 300b. The delivered chat room ID is transmitted to the client B 300b. Is displayed on the screen (see FIG. 11C). FIG. 11C illustrates a case where there are two chat rooms inviting user 2 and / or two chat rooms opened by user 2. User 2 can enter 'R1', a chat room invited by User 1 from the chat room list, and perform instant messaging with User 1. After entering the chat room 'R1', User 2 composes the chat content in the chat content creation box of client B 300b (the same as the bottom box of Figs. 9D and 11D). When the transmission is instructed, the MSG (Roomid, msg) including the conversation content (msg) (eg, hi) and the currently entered chat room ID is transmitted to the chat room manager 132 through the mobile gateway 120. At the same time, a message IN (Roomid, PID, Nick) indicating that Client 2 has entered the chat room and a message MSG (Roomid, PID, msg) created by User 2 are sent to Client A 300a. At this time, as shown in (d) of FIG. 9, the screen of the client A 300a notifies user 2 of the chat room entry and sequentially displays a message (eg, hello) sent by him. In response to this, when the user 1 also writes a message (msg) and issues a transmission instruction, the message MSG (Roomid, PID, msg) is sent to the mobile gateway 120, through which the client B 300b and the chat room manager 132 are sent. Each is delivered. In this way, users 1 and 2 can do instant messaging.

As such, clients of a conversation party (eg, clients A and B) enter the same chat room, and their session establishes a socket connection via that chat room, from which time messages from each client are queued. It is sent directly to another client without delay. Here, the socket connection between the mobile phones participating in the chat room or between the mobile phone and the PC is made by associating a room ID assigned to the chat room by the service system 100 and a mobile phone number (PID) participating in the chat room. Clients in this state are in a state of instant messaging. If a client has left the chat room and has not rejoined any other chat room, the client's session is still alive but not ready for instant messaging. In this case, the client may communicate with the PMIM service system 100 using the TCP / IP protocol. If the user terminates the PMIM client program using the function of 'program termination' (described later) on the client screen, the client's session is killed in the PMIM service system 100. If the user switches to the mobile state (described later) on the client screen (described later), the client program terminates on the client, but the session of the client is still saved in the PMIM service system 100. Maintain state. Therefore, instant messaging is not possible for the client, but SMS messaging is possible. If necessary, when the user executes the client program again, the client returns from the "mobile state" back to the "online state" so that the user can reenter the chat room and perform instant messaging again.

On the other hand, the present invention further provides another function for enhancing the convenience of use in addition to the function of enabling such instant messaging between two people. User 1 and 2 can also be instant messaging and change to a mobile state where a mobile phone call is possible. To this end, a 'MOBILE' button is provided at the upper left of the 'conversation' window as shown in (c) of FIG. 9. When this button is executed, the client exits the current chat room, and at the same time, the client program for PMIM is executed, and the mobile phone call is made available. This button changes the state of your mobile phone to the mobile state while User 1 and User 2 are instant messaging, for example when one of them needs to make a mobile phone call with a third party. Messaging allows you to proceed with SMS. This button terminates the online status for instant messaging and allows the user to exit the program while changing his status to mobile via a STATUS message. After that, the session manager 124 transmits all the messages in a short message. The client has been switched to this state in the session management unit 124 of the PMIM service system 100 and the session is still alive, but only the client program is terminated. Thus, the client can talk to the other party in a short message, and as long as the other party still remains in the chat room, he or she can continue the conversation by instant messaging. Clients that have been switched to mobile may join the original chat room by running the client program for PMIM again if necessary. Then again, both parties will be able to talk via instant messaging.

The diagram of FIG. 12 shows a process in which after client B 300b switches to a mobile state, client B 300b talks by SMS and client A 300a talks by instant messaging. Specifically, when the client B 300b terminates the PMIM client program, the client B 300b notifies the registration unit 134 through the mobile gateway 120 that its state is changed to the mobile state. From then on, Client B 300b is no longer a client of PMIM service system 100, but is simply an Agent 2 of User 2. Therefore, the message sent from the client A 300a to the user 2 is transferred from the mobile gateway 120 to the SMS gateway 140 again, and is converted into a short message (SMS) to the agent UA (B) of the user 2. The SMS message sent to the client A 300a by the UA B is transmitted to the mobile gateway 120 through the SMS gateway 140, converted into an instant message, and then transmitted to the client A 300a.

The PMIM client program provides several function buttons. 9E shows a toolbar in which function buttons provided are collected. The Chat Room List button displays a list of all the chat rooms you have created and the rooms you have invited. The End Chat button provides the ability to leave a chat room or exit the PMIM messaging environment completely. The Exit Program button completely exits the PMIM program, causing the client to go offline. The diagram of FIG. 13 shows the process of terminating an ongoing conversation and further terminating the PMIM client program. In order to end the current conversation and exit the chat room, the 'end conversation' button shown in (e) of FIG. 9 may be executed. Then, the conversation termination message OUT (Room ID) is sent from the client B 300b to the mobile gateway 120. The message is transmitted to the registration unit 134 and the chat room manager 132, respectively, indicating that user 2 has left the chat room. As a result, the screen of user 1's client A 300a indicates that user 2 has left the chat room. The chat room is still online. You can also enter ‘chat room list view’ to enter another chat room. When pressing the 'End Program' button on the client B 300b, as described above, the first step is to terminate the conversation, and then a status message (STATUS Offline) indicating that the client B (300b) is offline is displayed. 132 is communicated to the register 134. In addition, the chat room manager 132 notifies the client A 300a of the message OUT (RoomID, PID) indicating that the client B 300b has exited the chat room.

Another add-on is the ability to invite other users to have multiparty conversations using INVITE messages in chat rooms. A third party (client C 300c) can also be invited to the chat room while the two are talking via instant messaging. For example, when User 1 calls the toolbar of FIG. 9E and executes the 'Chat Request' button while chatting with User 2, Client A 300a displays a chat request screen as shown in FIG. do. If you are inviting an existing chat room, do not check "Open new chat room." In this screen, enter the mobile number of the person you want to invite and the contents of the conversation request and press a specific button on the mobile phone. Then, as shown in FIG. 14, the message INVITE (RID, PID, MSG) inviting the client C 300c is transmitted from the client A 300a to the mobile gateway 120. The invitation message includes the inviting chat room ID (RID), client C's mobile phone number (PID), and the chat request contents (MSG). In the same manner as the procedure of inviting the other party to the conversation in FIG. 8, the message is transmitted to the session managing unit 124 so as to grasp the current state of the client C 300c so that the client C 300c is currently connected to the PMIM service system 100. If it is not logged in, the conversation invitation message is transmitted to the client C 300c through the SMS gateway 140. If you want to open a new chat room and invite the client C (300c) to the chat room, check the 'open a new chat room' in the chat request screen of FIG. In this case, as shown in FIG. 8, after requesting a conversation without a chat room ID (RID), a new chat room is opened and an invitation message is sent.

The process in which the client C 300c receives the conversation invitation SMS to join the conversation is illustrated in FIG. 15. This process is almost the same as the process shown in FIG. 10 except that the message sent by the client C 300c is sent not only to the client A 300a but also to the client B 300b. That is, the client C 300c receiving the invitation message from the PMIM service system 100 downloads the client program for PMIM and participates in the conversation. When the client C 300c transmits the message, the mobile gateway 120 receives the message and passes the message to the chat room manager 132. The chat room manager 132 automatically transmits the message to all participants participating in the chat room. At this time, the mobile module 120 is responsible for the final module for delivering the message.

As another feature, one person can join several chat rooms. It is possible to move to another chat room that you want to participate from among the currently opened a plurality of chat rooms by using the 'view chat room list' on the left side of the toolbar of FIG. 9 (e). In this case, the present participant chat room is changed within the client itself without exchanging a special message with the PMIM service system 100. If a chat is requested while participating in another chat room, a chat message is displayed along with the chat room ID at the bottom as shown in FIG. The user can select a chat room using the toolbar to join another chat room.

As described above, the user may maintain his / her status in various ways such as online status, mobile status, status, internet status, and the like. The ability for the user to give priority to these states may be added to the client program for PMIM. The priority set using this function is provided to the service system 100 and registered. Then, when a conversation request is received for the user, the service system 100 allows the user to send and receive messages according to the priority registered by the user. Here, the online state is a state capable of instant messaging on the basis of a wireless Internet using a mobile phone, the Internet state is a state capable of instant messaging on a wired Internet basis using a personal computer, and the mobile state is a mobile phone call on a mobile phone And short messaging can be done at the same time. Furthermore, the user can send and receive messages simultaneously through the mobile phone and the PC while maintaining not only one of the three states but also a plurality of states, for example, the online state and the PC internet state. To this end, such a request is registered in the service system 100, and the service system 100 simultaneously transmits a message transmission to the mobile phone and the PC when the user is registered with a plurality of states of parallel maintenance.

In addition, the operator of the service system 100 may be able to make additional advertising revenue by having a function of transmitting a simple advertising message together using a message protocol in an appropriate state in delivering instant messages between the parties.

In the above, the present invention has been described using a case where the communication base is a wireless Internet environment as an example. However, the present invention is not limited thereto and may be modified and applied to other wireless communication environments, such as a Wibro system.

The present invention can improve the limitations and inconveniences of use of the short message service and the computer-based instant message service of the existing mobile phone. In other words, by using the present invention, the user does not have to go through the cumbersome procedure of registering for a service providing site or registering a conversation partner as a friend in order to use the service of the present invention. You can only use a mobile phone or PC with a client program, and if you know the mobile phone number of the other party, you can instant messaging with that person. Furthermore, the conversation can be made in a longer sentence than a short message (SMS), and the instant messaging is possible because the present invention enables a conversation through a socket connection, whereas the SMS cannot guarantee a real time conversation or an instant conversation when the queue is long. Do. In addition, by enabling various types of conversations such as SMS type conversation and instant messaging using PC, in addition to the instant messaging method using a mobile phone, the user has the convenience of choosing and choosing a conversation method suitable for his situation. .

Although described above with reference to a preferred embodiment of the present invention, those skilled in the art various modifications and changes to the present invention without departing from the spirit and scope of the invention described in the claims below You can. Accordingly, all changes that come within the meaning or range of equivalency of the claims are to be embraced within their scope.
