Claim Text:
1. A method of providing internet protocol (IP) data communication in a near field communication (NFC) peer-to-peer communication environment, comprising: establishing an NFC peer-to-peer link between an initiator NFC device and a target NFC device; transmitting, by the initiator NFC device, a first configuration frame comprising IP configuration parameters associated with the initiator NFC device to the target NFC device via a NFC interface; receiving, by the initiator NFC device, a second configuration frame comprising IP configuration parameters associated with the target NFC device via the NFC interface in response to the first configuration frame; identifying, by the initiator NFC device, whether a first IP address of the initiator NFC device comprised in the first configuration frame is identical to a second IP address of the target NFC device comprised in the second configuration frame; if the first IP address of the initiator NFC device is identical to the second IP address of the target NFC device, transmitting, by the initiator NFC device, a message indicating failure to the target NFC device and identifying, by the initiator NFC device, a third IP address of the initiator NFC device to transmit the third IP address to the target NFC device; setting up, by the initiator NFC device, an IP communication with the target NFC device over the NFC interface based on the IP configuration parameters associated with the target NFC device; and exchanging by the initiator NFC device, IP data with the target NFC device over the NFC interface in an NFC peer-to-peer mode if the IP communication is set up.
