Terminals having an Internet protocol address, such as a smart phone, may be connected to a local area network (LAN) to exchange data with a counterpart terminal or to perform interconnection for a call.

Conventionally, a registration server has been operated to manage Internet protocol addresses on a communication network such as a local area network to interconnect terminals.

A terminal connected to a local area network may be reassigned an Internet Protocol address whenever a user changes or newly connects. The registration server thus has a function of managing an internet protocol address which is reallocated and changed for the same terminal connected on the communication network.

That is, the registration server stores data by associating a unique number such as a telephone number previously assigned to a terminal with a changed Internet protocol address through a registration procedure, and a terminal attempting to access the terminal wants to access the assigned unique number of a specific terminal. The Internet protocol address of the terminal corresponding to the unique number is provided to the terminal attempting to connect to enable interconnection for communication between the terminals.

However, a registration server operating in a communication network such as a local area network may be expensive to install and maintain and manage. Therefore, the communication network below a certain size has difficulty in operating the above-described registration server in consideration of economics.

Accordingly, there is a need for the development of a service technology capable of performing a connection for communication between terminals having an Internet protocol address such as a smart phone in a small communication network.

However, the following embodiments are provided to those skilled in the art to fully understand the present invention, and may be modified in various forms, and the scope of the present invention is limited to the embodiments described below. It doesn't happen.

The embodiment according to the present invention does not rely on a specific server that manages an Internet protocol address in a state in which a smart phone or a terminal having an internet protocol address (hereinafter, referred to as a "terminal") as shown in FIG. 1 is connected to a local area network. It has a configuration for establishing a mutual connection by finding a counterpart terminal that does not know the Internet protocol address as a recognizer.

In an embodiment according to the present invention, the recognizer may be set as shown in Table 1 below.


Recognizer
CODE 1 CODE 2 CODE 3 CODE 4 Terminal A Japan-Japan 3rd year 5 class A Terminal B Japan-Japan 3rd year 5 class B Terminal C Gurojung 2nd grade 3 class C

 The recognizer may be set to have a combination of subdivided code values (Code 1, Code 2, Code 3, and Code 4), and the identifier may be searched by searching the code values included in the recognizer.

The recognizer can be set by the user according to a communication protocol, unlike a unique code (telephone number) assigned by a communication company, etc. for communication to a terminal, and the user can express a word or code or terms that can easily identify him or her. You can create an identifier and set it on your terminal. Table 1 shows an example of the recognizers including their school (code 1), grade (code 2), class (code 3), and name (code 4).

The identifiers set as described above may be set for each of the terminals 10, 12, 14, and 16 connected to the network as shown in FIG. 1, and these identifiers may be used as identifiers of the respective terminals.

Here, as an embodiment of the present invention, a communication network (LAN) may be described as a local area network, but a network operated by an Internet protocol address based on an address system may be used as the communication network (LAN) of the embodiment according to the present invention.

In addition, the terminals 10, 12, 14, and 16 configured for the embodiment according to the present invention have a communication application, and the communication application is a program in a programming language that can design the application to have a call, scan, and update function. It can be configured with the software.

In the system environment according to the present invention as shown in FIG. 1, each terminal 10, 12, 14, and 16 may be configured to manage its identifier and Internet protocol address as a communication application. Herein, the terminal 10 is described as a calling terminal, and it is assumed that there is a destination terminal to be connected among the terminals 12, 14, and 16. In addition, the terminal 12 has a recognizer set up as the terminal A of <Table 1>, the terminal 14 has a recognizer set up as the terminal B of <Table 1>, and the terminal 16 has a recognizer It is assumed that the terminal C is set as shown in Table 1.

Assuming that a call is performed in the terminal 10, an operation according to the call function of the embodiment will be described with reference to FIG.

First, the terminal 10, which is a calling terminal, which wants to call, transmits a specific code included in the identifier, that is, “Japan-Japan”, through the communication network to request a response of the target terminal using a communication application.

In this case, the terminal 10 transmits the identifier, a method of requesting a response of a terminal having a matching identifier or the Internet by broadcasting the identifier to all terminals connected to the communication network in a multicasting manner. By sequentially changing or decreasing the protocol address, the protocol address may be sequentially changed to find a terminal having a matching identifier among terminals connected to the communication network, and request a response.

As described above, when the recognizer is cast to the LAN in the terminal 10, the terminals 12 and 14, which are destination terminals having matching identifiers among the terminals 12, 14 and 16, perform a response. The terminal 10 transmits its own Internet protocol address information together with the identifier information searched to request a response, and the terminals 12 and 14, which are the target terminals, check their identifiers to check If it matches with, it sends a response message including its internet protocol address (10.1.3.1 or 10.1.3.2) to the internet protocol address of the calling terminal 10.

When one terminal responds, the communication application of the terminal 10 displays the Internet protocol address of the target terminal corresponding to the recognizer so that the user selects it for the connection, and two or more terminals respond ( In the case of Respond), the recognizer may display two or more different Internet protocol addresses corresponding to the same but select the Internet protocol address of the target terminal for the connection.

The terminal 10 as a calling terminal stores and manages the Internet protocol addresses included in the recognizer and the response message as a list.

Thereafter, the terminal 10 as a calling terminal performs a connection when the user selects the Internet protocol address of the target terminal displayed by the communication application, and thus the terminal 10 sends a message for connection to the target terminal. (In Fig. 2, the terminal A on the table 1, that is, the terminal 12 is selected as the target terminal), and communication for data transmission or voice call is performed between the terminal 10 and the terminal 12.

As described above, the calling function can be performed, and the terminal 10, which is the calling terminal, stores the identifiers and the corresponding Internet protocols as a list, so that the user must remember the identifiers and the Internet protocols for later calling. Relief can be solved.

In addition to the call function, a scan function as shown in FIG. 3 may be implemented in a communication application according to an embodiment of the present invention.

The scanning function may be performed periodically by a communication application set in the terminal 10 as a calling terminal or by user selection, and the communication application transmits a scan message on a communication network (LAN) and mounts a communication application to scan a message. It is possible to manage identifiers and Internet protocol addresses of terminals responding to (in this case, all responding terminals correspond to the target terminals) as a list.

That is, as shown in FIG. 3, the terminal 10 broadcasts a scan message " ALL " previously promised through a communication network LAN or sequentially changes Internet protocol addresses. Then, terminals with the same function set up on the LAN, that is, the same communication application, recognize the "ALL" as a scan message and perform a response to call a response message including its identifier and the Internet protocol address. It transmits to the terminal 10 which is a terminal.

As described above, when the response message is transmitted from the terminals configured with the same function on the communication network, the terminal 10 as the calling terminal may prepare a list of terminals presently operable on the communication network LAN. The user can easily communicate with the destination terminal using the identifier and the Internet Protocol address in the.

In addition, an embodiment according to the present invention may include an update function in addition to the scan function of FIG. 3 in a communication application.

The updating function broadcasts the identifier included in the list secured by the calling function or the scanning function described above or sequentially changes the Internet protocol address to find and update the changed current Internet protocol address of the identifier.

The updating function may be performed by updating the list of internet protocols sent from the target terminals responding to the responder on the LAN as shown in FIG.

If there is no response to an identifier present on the original list while performing the update function, the terminal having the identifier may be understood as being out of the network or the function is abnormal.

As described above, an embodiment according to the present invention provides a desired target terminal as a communication protocol mounted in each terminal, a recognizer and an internet protocol address set therein, without having to install a server for managing an internet protocol address on a communication network such as a registration server. It can call, scan valid terminals accessible on the network, and update the list obtained by calling or scanning.

Therefore, according to the present invention, a service capable of access for communication between terminals having an Internet protocol address, such as a smart phone, can be implemented even in a small communication network where the registration server is not economically installed.

It will be appreciated by those skilled in the art that changes may be made to the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
