Abstract

A method for transmitting and receiving data according to connection priority between terminals in a Near Field Communication (NFC) system is provided. The method includes: if there is data to transmit, determining a proportional fairness (PF) value for determining a connection priority of a first connection established for direct communication between the first terminal and the second terminal; sending the determined PF value to the second terminal to request data transmission over the first connection; and sending data to the second terminal if information authorizing data transmission over the first connection is received from the second terminal.

Description

Technical field [0001] The invention relates to a communication system. More specifically, the present invention relates to an apparatus and method for transmitting and receiving data according to connection priority between terminals in a near field communication system that performs direct communication between devices. Background technique [0002] Near Field Communication (NFC) is a technology used for very short-range wireless communication. NFC may include device-to-device communication or Ad-hoc communication that performs direct communication between devices without a repeater. [0003] In an NFC network with multiple connections for terminals that can attempt direct communication between terminals, the multiple connections may occasionally attempt data transmission at the same time. In this case, if a connection uses the same frequency band as its adjacent connection, the communication of the connection may conflict with the communication of the adjacent connection. The...
