Interconnection method and system based on Wi-Fi aware protocol, and master device in NAN group

A master device in a neighbor awareness networking (NAN) group comprising:

• one or more processors;
• a memory;
• and
• one or more application programs, wherein the one or more application programs are stored in the memory and are configured to be executed by the processor to perform operations, the operations comprise:
• sending, by the master device, a discovery beacon frame outside a transmission window to discover a neighboring device, the neighboring device joining the NAN group according to the discovery beacon frame;
• sending, by the master device or a non-master sync device in the NAN group, a synchronization beacon frame in the transmission window, and each of devices sending at most once in one transmission window to synchronize clocks of devices in the whole NAN group;
• obtaining, by each of the devices in the NAN group, upper layer application information of another device through a service discovery frame, and generating a NAN group device application statistics table locally in the device to complete networking of NAN group devices;
• and
• two or more devices in the NAN group starting an upper layer application through looking up the NAN group device application statistics table.
