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

1 is a schematic block diagram of one terminal capable of performing multi-party information transmission and reception capable of performing multi-party communication according to the present invention. As shown in FIG. 1, there are two RF (Radio frequency) units 100 and 122 in one terminal. The first RF 100 is provided to transmit and receive a signal to and from a base station to perform communication through a wireless network of a carrier, and the second RF 122 is included in the short range communication module 120 to be located near the terminal. It is provided for transmitting and receiving data without passing through a terminal and a wireless communication network.

The first RF 100 is connected to a central processing unit 104 that performs all communication processes. The central processing unit 104 is connected to a first memory 102 for storing data, an input / output (I / O) interface 106, a coder / decoder (CODEC), and a near field communication module 120. . The I / O interface 106 performs an interface between the keyboard 110 and the display unit (eg, LCD), and the CODEC 108 is connected to the speaker 114 and the microphone 116 to encode and decode data. do.

The short range communication module 120 connected to the central processing unit 106 includes a module controller 124 and a second memory 126 in addition to the above-described second RF unit 120. The module control unit 124 includes a link manager and a link control unit. The short range communication module 120 may perform the following communication with the terminal and other short range portable terminals.

Each communication terminal according to the present invention can send a connection request to each other through a short-range communication module. Receiving the connection request, the terminal responds and establishes a connection to the communication unit. In this process, connection information is generated and recorded in the memory. That is, terminals wishing to be interconnected indicate that the interconnection is established. If there is a connection request from an additional terminal or a connection is made with an additional terminal from a terminal that is currently forming a connection, the server, which plays a main role among the two terminals, accepts the terminal connection and establishes a connection and connects the connection information. Update the. If there is information to be transmitted through the mutual connection in each terminal in the state in which the connection is formed, the corresponding terminal first transmits the information to the terminal acting as a server. The terminal acting as a server grasps the nature of the collected information, processes it, and distributes the information to the terminal to which the information should be sent. In this case, if there is no information to be transmitted, a process of checking whether a termination condition is generated from the terminal in the connection information is generated. When the termination condition occurs, the connection information is updated and the connection information is distributed to each terminal. If all connections are not terminated, the process of checking if there are additional connections is repeated. That is, in the present invention, the terminal transmits the information to the terminal serving as a server based on the connection information, and analyzes the corresponding information, thereby distributing and transmitting the information to the terminal registered as the connection information. This will be possible.

Hereinafter, a multi-party information transmission / reception method according to the present invention performed between the terminals described with reference to FIG. 1 will be described with reference to FIGS. 2A and 2B. Information transmission and reception is performed in at least two terminals.

As shown in FIG. 2A, a first terminal (hereinafter referred to as a server) is first conducting a call through the first RF 100 (S200). At this time, the second terminal (hereinafter referred to as a client) adjacent to the server determines whether to add a call to the server's call (S202), and when the call is requested, the central processing unit of the client links the data with the server. The request signal is transmitted to the module controller of the short range communication module (S204). Thereafter, the module control unit of the client transmits a data link connection request to the server through the second RF (S206). The data link connection request received through the RF of the server is received by the module control unit of the server, and the received signal is transmitted to the central processing unit of the server (S208). Thereafter, it is determined whether the server's central processing unit accepts the client's connection request (S210). At this time, when the server's central processing unit accepts the client's connection request, the server's central processing unit transmits the voice link connection request with the client to the module control unit of the short range communication module (S212). If the connection request is not accepted in step S210, the process proceeds to step S220 described later.

On the other hand, after performing step S212, the module control unit of the server transmits a voice link connection request with the client to the client through the second RF of the server (S214). Thereafter, the voice link connection request received through the second RF of the client is received by the module control unit of the client and transmitted to the central processing unit (S216). Thereafter, the client's central processing unit receives the server's voice link connection request to form a voice link. The process then proceeds to step S230, described below.

On the other hand, if it is not the request of the client to add a call in step S202, step S220 is performed to determine whether another client exists (S220). If there is a client added to the server in step S220 and there is a busy client, step S222 is performed to determine whether there is a client requesting to disconnect from the server. If there is a client requesting to disconnect from the server in step S222, the central processing unit of the client transmits a disconnection request with the server to the server through a data link (S224). If no other client exists in step S220, the process proceeds to step 236, which is described later. If the step S222 does not require disconnection with the server, the process is described in the following step ( Proceed to 232).

On the other hand, after performing step S224, the central processing unit of the server transmits a voice link and data link release request with the client to the module control unit of the server (S226). Next, the module control unit releases the voice link and the data link (S228).

Thereafter, after performing step S228 or after performing step S218 described above, the central processing unit of the server updates a table that stores connection information with the client (S230). Next, the voice signal from the client and the voice signal from the microphone of the server are mixed and transmitted to the external communication network through the first RF of the terminal (S232). Next, the voice signal input through the first RF from the external communication network is output to the speaker of the server and transmitted to the client via the voice link via the codec (when the PCM link is used) (S234). Next, in step 236, it is determined whether the call with the server is terminated. If the call of the server is terminated, the process terminates after disconnecting all the clients in step S238.

Applying the multi-party data transmission and reception method according to the present invention described above can perform the following functions. That is, it is possible to perform a three-way call method that can perform a call and a connection connected to one terminal without paying a separate cost. In addition, it is possible to directly communicate with two or more terminals can play a game between the terminals. In addition, if the usage information or operation program of the first terminal is updated, and if the second terminal also needs to update the usage information or operation program, there is no need to visit the manufacturer or dealer and receive an update service as it is currently used. The connection can remain the same.
