Abstract
A terminal supporting peer-to-peer (P2P) communication, wherein a transceiver of the terminal is implemented to support P2P communication with an adjacent terminal in the same cell. Thus, when short-range communication is possible, the terminal performs P2P communication directly with the adjacent terminal, not via a base station. Consequently, when terminals use different mobile telecommunication service providers or there is no base station network, the terminals can be used for short-range communication. More particularly, when a receiving channel state becomes satisfactory while communication with an adjacent terminal is being performed via a base station, the terminal directly switches to a P2P communication mode and performs communication with the adjacent terminal. On the contrary, when the receiving channel state deteriorates while communication with the adjacent terminal is being performed in the P2P communication mode, the terminal directly switches to a base station communication mode and performs communication with the adjacent terminal.
