SYSTEM AND METHOD FOR MULTIPLE CLIENTS SYNCHRONIZATION IN WI-FI PEER-TO-PEER GROUP

摘要

A method and a system of Wi-Fi P2P communication network which can synchronize a group owner and at least two group clients are disclosed. The system includes changing the attribute ID 19 of the P2P Attribute ID definitions of the Wi-Fi P2P Technical Specification to be P2P Active Session, and the types 9 and 10 of the P2P public action frame type to be Join Active Request and Join Active Response, respectively. The method includes having a second group client to send the P2P public action frame with Join Active Request to a group owner via a P2P active session already established by the group owner and a first group client to join the P2P active session. Thus, the group owner and the first and second group clients can synchronize with each other substantially at the same time by the P2P active session.
