Patent ID: 8463180

Claim:
A method for establishing a Peer-To-Peer (P 2 P) connection between Mobile Stations (MSs) in a communication system, the method comprising: transmitting a request signal requesting P 2 P communications with a second MS and a unique identification number of the second MS to a Base Station (BS), by a first MS; receiving from the BS a Connection IDentifier (CID) of the second MS allocated by the BS and transmission information required for initial synchronization of the P 2 P communications in response to the request signal, by the first MS; acquiring synchronization with the second MS using a synchronization signal generated by attaching the CID of the second MS to a Pseudo-Noise (PN) sequence and the transmission information, by the first MS; and establishing a P 2 P connection with the second MS, by the first MS, wherein the CID of the second MS is detected by using the unique identification number.
