Abstract
The invention relates to a method for discovering and realizing real-time communication of a device based on a wireless network. Mobile terminals in the same WLAN periodically transmit a data packet with self information to a wireless access device copying the data packet and distributing the data packets to other mobile terminals. The mobile terminals analyze the data packets, and therefore, TCP connections are set up by the real-time communication among the devices. Data sharing network information among the access devices is further obtained by the real-time communication; sharing network is set up among the access devices by the data sharing network information; the data sharing is realized. The method has the advantages of simpleness in operation, data traffic without extra cost, rapid, stable and multi-platform transmission, and more convenient data sharing among users.
