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

Figure 2 shows a block diagram for providing an instant messenger service of the present invention, Figure 3 shows a block diagram of the instant messenger software of the present invention, Figure 4 shows an instant in a network using the instant messenger software of the present invention It is a flowchart using a messenger service.

The present invention uses an instant messenger service without a separate server between users connected to a network by using peer-to-peer communication.

2 shows that a plurality of PC terminals 30 are connected to a network without a separate server.

In the case where the instant messenger software of the present invention is installed in the PC terminal 30 and the instant messenger service is used, it is possible to use the same layer communication without a separate service server.

In the PC terminal 30 of the present invention, not only the user's information but also the information of the counterpart users connected to the corresponding network using the messenger service can be managed to use the service without a separate server.

The user of the instant messenger service uses his or her PC terminal 30 to send and receive messages and data, to search for a specific user, and to generate specific list information that can be used by his or her own. Manage your instant messenger service.

When the PC terminal 30 searches for a specific accessor, when a query is transmitted to the network by a message, the terminal of the other accessor who receives the message detects the query and responds with a response message.

According to the query, the query is transmitted and received through the network using broadcast, unicast, and multicast methods.

3 shows the configuration of the instant messenger software of the present invention.

The instant messenger software 50 includes an instant message transceiving unit 52 for transmitting and receiving messages through peer-to-peer communication, and a user name, ID, phone number, and IP address using instant messenger software. A user registration unit 54 for publishing the necessary information to the connected network by inputting a message, a user status processing unit 56 which periodically transmits the status information of the user PC and receives and displays the status information of the counterpart contactor. Neighbor list unit 58 for identifying and managing a list of counterpart contacts connected to the network using the messenger software 50, a search unit 60 for searching for, identifying and registering a specific connected person, and a user separately Receiving information of a specific list unit 62 provided to create a group, a cafe, etc., and information of a specific user who registered a user It is provided to the registered list section 64, etc. showing me.

The user registration unit 54 manages not only the user's information, but also the information of the other accessor, which is received, publicly disclosed in the corresponding network, and used by the connected PCs.

The neighbor list unit 58 is a list of the correspondents connected to the network by using the instant messenger software 50, and the standard network protocols (netbios, IPX, ipv6, etc. protocols for discovering connected neighbors, A protocol used to find shared computers in Windows, etc., is used to find a terminal using instant messenger software 50 as in the current network, create a list, and store it in a PC.

According to the present invention, when a user is registered in advance in the user register 54 and disclosed to another user connected to the network, the standard network protocol and the messenger software add the currently connected counterparties to the neighbor list using the information registered in the user register. Figure out.

The neighbor list thus created is also open so that other accessors can query and refer to it when requesting, without requiring a separate server.

In addition, the search unit 60 to find a specific accessor can be found using three methods.

By using standard network protocols (protocols to find other neighbors such as netbios, IPX, etc.), you can automatically search public and collected information of terminals using instant messenger on the same subnet. Search and find the visitor.

In addition, when a query message is inputted to the network by inputting a keyword specifying a specific visitor, the PC of the other correspondent who receives the message searches for a specific visitor corresponding to the query message in his neighbor list. .

If there is a specific visitor, the information of the specific visitor and the network address (MAC address, IP address, etc.) are transmitted to the user who inquires as a response message.

The query uses a broadcast sent to the terminals of all the correspondents connected to the network using the instant messenger service.

In addition, if a user registers a name or IP address, which is information of a specific user, the instant messenger service can be used in the network even if the user does not search the list.

The specific list unit 62 is provided so that an instant messenger service can be used by creating a community or a cafe between users.

The list unit 64 that registers me records and displays information registered by a specific visitor in a specific list item, and receives and registers ID and IP address information of the specific accessor. That is, when the counterpart contactor registers the user in a specific list, the information of the counterpart contactor is also recorded and stored in the list unit 64 that registered me.

The user status processing unit 56 grasps the status of the user's PC currently online, offline, rest, etc., and the PC using the instant messenger service periodically unicasts the status information message and transmits it to the network. The information is sent to the terminal of the specific visitor in the list unit 64 that has registered me.

The terminal of the other party receiving the status message can know what status the user is currently through the status message, and the messenger software displays the current status of the user. On the other hand, if the status information message does not come from the user for a certain time, the status is updated offline.

In some cases, multicast-enabled networks send my status information to the multicast. Multicast is a bucket relay method in which a person sends information to several people and receives the same content in a sub-network connected to a local area network or the Internet. It is a transmission method for a specific large number of people who propagate the information by transmitting to the person.

4 is a flowchart of using an instant messenger service in a network using the instant messenger software of the present invention. First, the instant messenger software is installed and executed in the user's PC 30 (S80).

The user registers and selects information such as his name, ID, IP address and telephone number in the user registration unit 54 to disclose necessary information (S82).

When the instant messenger software is executed, the neighbor list unit 58 grasps the relative accessors connected to the network using a standard network protocol, generates a list, stores it, and publishes it (S84).

In addition, the user searching for a specific user who will use the instant messenger service may be searched by the search unit 60 using a standard network protocol, or may be found in a list generated by the neighbor list unit.

In addition, if the user has a specific accessor's name, ID and IP address information can be found by entering it (S86).

The user can use the instant messenger service by searching for a specific user and joining or joining a group, cafe, etc. created by the other user, and use the instant messenger service. Create and chat with other parties or send data (S88 ~ S90).

As described above, the present invention uses an instant messenger service to connect to a network using peer-to-peer communication without establishing a separate instant messenger service server. Record other identifying items such as name, phone number, address, IP address information and other nicknames, which are unique information of the user, and disclose necessary information. You can find the other person.

In addition, when a network provides a broadcast method or multicast, an instant messenger service can be used at a higher speed.

The present invention installs instant messenger software on a user's PC, finds a desired counterpart connected to a network, and can perform activities such as a group, as well as chatting and data transmission.

As described above, since the instant messenger service can be used without a separate service providing server of the present invention, the cost and the number of people can be greatly reduced. In addition, you can build instant messenger system automatically without any administrator.
