The present invention discloses a device communication method and system based on WI-FI Aware. The method comprises the steps that: (A) a center device and a peripheral device are interconnected through the WI-FI Aware, a group formed by the center device and the peripheral device is established, wherein the peripheral device comprises a peripheral communication device and at least one answering device, and (B) when other devices sends a communication request to the center device or the communication peripheral device, the center forwards the communication request to the answering device, and the answering device answers and processes the communication request. According to the method and the system, the interconnection networking of the center device and a peripheral device through the WI-FI Aware is realized, the answering device carries out unified processing on the communication request sent to the center device and the peripheral communication device, the real-time communication without switching can be carried out, and the problem of switching in multiple device communication when the multiple devices are interconnected through Bluetooth is avoided.
