Abstract

Provided is a device that performs wireless communication with a second communication terminal via a server, the device including a communication determiner that determines whether to perform communication in a long-range wireless communication mode, which is a communication mode for communicating with the second communication terminal by using the server; a communicator, which, based on the determination, transmits a connection request to the server and receives a response message including authentication information for establishing communication with the second communication terminal from the server; and a controller, which controls the first communication terminal to perform wireless communication with the second communication terminal in response to the response message.

First claim

1 . A first communication terminal performing wireless communication with a second communication terminal via a server, the first communication terminal comprising:
a communication determiner configured to determine whether to perform communication in a long-range wireless communication mode, which is a communication mode for communicating with the second communication terminal by using the server; a communicator configured to, based on the determination, transmit a connection request to the server and receive a response message including authentication information for establishing communication with the second communication terminal from the server; and a controller configured to control the first communication terminal to perform wireless communication with the second communication terminal in response to the response message, wherein the authentication information comprises information regarding a result of authentication determined based on whether the first communication terminal is included in a list of trusted devices of the second communication terminal.

2 . The first communication terminal of claim 1 ,
wherein the connection request comprises identification information regarding the second communication terminal and identification information regarding the first communication terminal, and wherein the identification information regarding the first communication terminal comprises authentication information for short-range wireless communication and/or long-range wireless communication of the first communication terminal.

3 . The first communication terminal of claim 1 , wherein the list of trusted devices of the second communication terminal comprises information regarding communication terminals that have previously performed short-range wireless communication with the second communication terminal.

4 . The first communication terminal of claim 1 ,
wherein the communicator is further configured to transmit a control signal of the second communication terminal based on a user input to the server, and wherein the response message comprises information regarding a result of performing at least some of functions of the second communication terminal according to the control signal.

5 . The first communication terminal of claim 4 , wherein at least some of the functions comprise one of a phone call transmitting function, a phone call receiving function, a message transmitting function, and a message receiving function.

6 . The first communication terminal of claim 1 , further comprising:
a converter configured to convert a voice signal to a data packet and convert a data packet to a voice signal, wherein the communicator is further configured to transmit the data packet converted from the voice signal to the server and receive a data package converted from a voice signal by the second communication terminal from the server.

7 . The first communication terminal of claim 1 , wherein the communication determiner is further configured to determine whether to perform communication in the long-range wireless communication mode when there is data that needs to be transmitted to the second communication terminal or when the second communication terminal is disconnected.

8 . The first communication terminal of claim 1 , further comprising:
an authenticator configured to request the server to authenticate the first communication terminal by transmitting account information, wherein the communicator is further configured to perform data interaction with the second communication terminal authenticated by the server via the server.

9 . A method by which a first communication terminal performs wireless communication with a second communication terminal via a server, the method comprising:
determining whether to perform communication in a long-range wireless communication mode, which is a communication mode for communicating with the second communication terminal by using the server; based on the determination, transmitting a connection request to the server; receiving a response message including authentication information for establishing communication with the second communication terminal from the server; and controlling the first communication terminal to perform wireless communication with the second communication terminal in response to the response message, wherein the authentication information comprises information regarding a result of authentication determined based on whether the first communication terminal is included in a list of trusted devices of the second communication terminal.

10 . The method of claim 9 ,
wherein the connection request comprises identification information regarding the second communication terminal and identification information regarding the first communication terminal, and wherein the identification information regarding the first communication terminal comprises authentication information for short-range wireless communication and/or long-range wireless communication of the first communication terminal.

11 . The method of claim 9 , wherein the list of trusted devices of the second communication terminal comprises information regarding communication terminals that have previously performed short-range wireless communication with the second communication terminal.

12 . The method of claim 9 ,
wherein, in the transmitting, a control signal of the second communication terminal based on a user input is transmitted to the server, and wherein the response message comprises information regarding a result of performing at least some of functions of the second communication terminal according to the control signal.

13 . The method of claim 9 , further comprising transmitting a data packet converted from a voice signal to the server;
receiving a data package converted from a voice signal by the second communication terminal from the server; and converting the data packet received from the server to a voice signal.

14 . The method of claim 9 , wherein, in the determining, it is determined whether to perform communication in the long-range wireless communication mode when there is data that needs to be transmitted to the second communication terminal or when the second communication terminal is disconnected

15 . The method of claim 9 , further comprising:
requesting the server to authenticate the first communication terminal by transmitting account information; and performing data interaction with the second communication terminal authenticated by the server via the server.
