Method and apparatus for adaptive peer to peer communication selection in wireless communication system

A method of operating a transmitting Mobile Station (MS) for establishing a communication mode between the transmitting MS and a receiving MS in a wireless communication system, the method comprising:

• after requesting a connection to a Base Station (BS), broadcasting a Peer to Peer (P2P) report request message to one or more neighbor MSs, the P2P report request message checking possibility of a P2P communication with the receiving MS;
• after broadcasting the P2P report request message, receiving a connection response message from the BS indicating whether the P2P communication with the receiving MS is possible;
• and
• establishing a connection with the receiving MS in a desired communication mode according to the connection response message.

A method of operating a receiving Mobile Station (MS) for establishing a communication mode between MSs in a wireless communication system, the method comprising:

• after receiving a Peer to Peer (P2P) setup ready message for instructing preparation of P2P setup from a Base Station (BS), preparing P2P setup;
• after preparing the P2P setup, receiving a P2P report request message for checking possibility of a P2P communication from a transmitting MS;
• and
• reporting P2P-related information to the BS in response to the P2P report request message.

A Base Station (BS) apparatus for establishing a communication mode between Mobile Stations (MSs) in a wireless communication system, the apparatus comprising:

• a controller for broadcasting an instruction message to one or more neighbor MSs upon receiving a connection request message from a transmitting MS, for receiving P2P-related information from a receiving MS among the one or more neighbor MSs in response to the reception by the receiving MS of a P2P report request message broadcast from the transmitting MS, and, if a P2P communication is possible between the transmitting MS and the receiving MS, for transmitting a connection response message to the transmitting MS and the receiving MS;
• and
• a mode selector for selecting a communication mode by determining whether the P2P communication is possible between the transmitting MS and the receiving MS according to the P2P-related information,
• wherein the instruction message includes a message instructing the neighbor MSs to prepare to receive the P2P report request message from the transmitting MS.
