Description
Technical field
The present invention relates to wireless communication technology field more particularly to a kind of method and devices for establishing WiFi P2P connection.
Background technique
P2P (Peer-to-Peer, end-to-end) is a kind of end-to-end scene technology in Wi-Fi technology, two or more
A equipment may be implemented to communicate between each other by just constituting a small-scale network architecture after the connection of P2P technology.
As shown in Figure 1, existing Wi-Fi P2P establish before connection need to be scanned (scan), monitor (listen),
Search for (search) three phases.Wherein, scan phase is to carry out all channel scanning in channel 1~13, and the search phase is to believe
Road 1,6,11 carries out.
P2P usage scenario is generally divided into two kinds: interim P2P scene and permanent P2P scene.
Interim P2P scene: after establishing P2P connection between two mobile phones, interim group is just it has been established that if third platform
Cell phone apparatus wants that connection is added, and does not need again to scan 1~13 all channel of Wi-Fi again one time, because group before builds
Vertical just to have determined that channel, in spite of there is all channel scanning, the suitable channel that finally can all negotiate to confirm to one is built
Vertical connection.
Permanent P2P scene: for a printer scene, when thering is other equipment to want to be added, due to being to build
A permanent group is found, equipment must carry out all channel scanning, can just find suitable equipment and establish connection therewith.
Currently, whether interim P2P scene or permanent P2P scene, will carry out complete when establishing WiFi P2P connection
Scan channel, and do not need to carry out all channel scanning, therefore existing WiFi P2P in fact for interim P2P scene
Establishment of connection process is not reasonable.
