A method for communication link setup in a first electronic device includes: setting up an EFC link with a second electronic device; determining connection setup information of the second electronic device through the EFC link; and setting up a short range communication link with the second electronic device based on the connection setup information. ## Claims ### Claim 1 A method for establishing a communication link in a first electronic device, comprising: establishing an Electric Field Communication (EFC) link with a second electronic device; determining connection setup information of the second electronic device through the EFC link; and establishing a short range communication link with the second electronic device by using the connection setup information. ### Claim 2 (depends on 1) The method of claim 1, wherein the EFC link includes a communication link set up by using an electric field generated by a portion of a body. ### Claim 3 (depends on 1) The method of claim 1, wherein establishing the EFC link comprises: determining whether there is a peripheral electronic device capable of setting up the EFC link using an electric field; and establishing the EFC link with the second electronic device when the EFC link setup with the second electronic device is possible. ### Claim 4 (depends on 1) The method of claim 1, wherein the short range communication includes any one of a Bluetooth scheme, a Wireless Local Area Network (WLAN) scheme, an Infrared Data Association (IrDA) scheme and a Near Field Communication (NFC) scheme. ### Claim 5 (depends on 4) The method of claim 4, wherein the connection setup information includes at least one of a Bluetooth address and a Bluetooth profile of the second electronic device. ### Claim 6 (depends on 4) The method of claim 4, wherein the connection setup information includes Extensible Authentication Protocol (EAP) authentication information. ### Claim 7 (depends on 1) The method of claim 1, further comprising communicating data with the second electronic device through the short range communication link after establishing the short range communication link. ### Claim 8 A first electronic device, apparatus comprising: an Electric Field Communication (EFC) unit; a communication unit for short range communication; at least one processor; a memory; and at least one program stored in the memory and executed by the processor, wherein the program includes at least one instruction for establishing an EFC link with a second electronic device; determining connection setup information of the second electronic device through the EFC link; and establishing a short range communication link with the second electronic device through the communication unit using connection setup information of the second electronic device ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the EFC unit establish the EFC link by using an electric field generated by a portion of a body. ### Claim 10 (depends on 8) The apparatus of claim 8, wherein the processor further configured to determine whether there is a peripheral electronic device capable of setting up the EFC link using an electric field, and set up the EFC link with the second electronic device when the EFC link setup with the second electronic device is possible. ### Claim 11 (depends on 8) The apparatus of claim 8, wherein the short range communication includes any one of a Bluetooth scheme, a Wireless Local Area Network (WLAN) scheme, an Infrared Data Association (IrDA) scheme and a Near Field Communication (NFC) scheme. ### Claim 12 (depends on 11) The apparatus of claim 11, wherein the connection setup information includes at least one of a Bluetooth address and a Bluetooth profile of the second electronic device. ### Claim 13 (depends on 11) The apparatus of claim 11, wherein the connection setup information includes Extensible Authentication Protocol (EAP) authentication information. ### Claim 14 (depends on 8) The apparatus of claim 8, wherein the communication unit communicates data with the second electronic device through the short range communication link after establishing the short range communication link with the second electronic device. ### Claim 15 A first electronic device, apparatus comprising: an Electric Field Communication (EFC) unit for establishing an EFC link with an second electronic device and determining connection setup information of the second electronic device through the EFC link; and a communication unit for establishing up a short range communication link with the second electronic device using the connection setup information. ### Claim 16 (depends on 15) The apparatus of claim 15, wherein the EFC unit establish an EFC link by using an electric field generated by a portion of a body. ### Claim 17 (depends on 15) The apparatus of claim 15, wherein the EFC unit determines whether there is a peripheral electronic device capable of setting the EFC link using an electric field, and sets up the EFC link with the second electronic device when the EFC link setup with the second electronic device is possible. ### Claim 18 (depends on 15) The apparatus of claim 15, wherein the short range communication includes any one of a Bluetooth scheme, a Wireless Local Area Network (WLAN) scheme, an Infrared Data Association (IrDA) scheme and a Near Field Communication (NFC) scheme. ### Claim 19 (depends on 18) The apparatus of claim 18, wherein the connection setup information includes at least one of a Bluetooth address and a Bluetooth profile of the second electronic device. ### Claim 20 (depends on 18) The apparatus of claim 18, wherein the connection setup information includes Extensible Authentication Protocol (EAP) authentication information.
