A MOBILE STATION APPARATUS FOR SUPPORTING PEER-TO-PEER COMMUNICATIONS AND A COMMUNICATING AND BILLING METHOD BASED ON THE SAME

摘要

A terminal capable of P2P(Peer-to-Peer) communication, a communication method using the same, and a billing method based on the same are provided to enable a terminal to perform P2P communication without having a short range communication module. A terminal capable of P2P communication comprises a transmitting module(220), a receiving module(230), a received channel measurement part(240), and a communication mode control part(250). The transmitting module(220) modulates and spreads Tx data and outputs a certain Tx signal. The receiving module(230) receives a downstream signal from a base station or a P2P signal from an adjacent terminal, despreads and demodulates the received signal, and outputs certain Rx data. The received channel measurement part(240) measures strength of the received signal by using averaging processing. The communication mode control part(250) controls handover between a base station communication mode and a P2P communication mode according to the measured strength.
