Disclosed is a message communication method of transmitting and receiving a certain message, independently of any network, without privacy invasion issues. The method includes generating vendor specific data on the basis of input information, adding the generated vendor specific data to a P2P information element of a probe request frame, and transmitting the probe request frame to another message communication apparatus. Thus, an apparatus conforming to a Wi-Fi Direct standard may transmit/receive a certain message to/from another terminal independently of a use region, a use environment, and a network of a large telecommunication vendor, without privacy invasion issues.
