Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the invention discloses a kind of method and device of data interaction, to realize the super low-power consumption data interaction of WIFI equipment.
See Fig. 1, the method for a kind of data interaction that the embodiment of the present invention provides, comprising:
The request of data ProbeRequest that S101, receiving terminal send;
Concrete, the terminal in the present embodiment is WIFI equipment, is in super low-power consumption pattern when the Station in WIFI equipment is flat, and WIFI is in IDLE state.When needing when there being data to send, CPU wakes up, be ProbeRequest packet data encapsulation, wake WIFI chip up, send this management frame data, here management frame data is the data that ProbeRequest sends, and the initial data in ProbeRequest hereinafter, can be understood as the data of carrying in management frames.
Existing management frames supports User Defined IE.The present embodiment defines a special user IE and is used for realizing data interaction.The OUItype of this IE is C8-93-46, and the type of data uses 1=Station reported data, and 2=AP replys data.When WIFI equipment has data to need to send, use ProbeRequest to carry data by this IE and use ProbeResponse to carry this IE data recovery to WIFI equipment to AP end (Accesspoint, wireless network node), AP end.
Concrete, WIFI management frames is made up of a lot of IE (informationelement).Each IE frame format definition is as shown in table 1:
Table 1
| 0xDD(1B) | Length(1B) | OUIType(3B) | Data… |
Wherein length is the total length that 3 bytes of OUIType add follow-up Data data, maximum can not more than 255.
S102, the initial data of resolving in described ProbeRequest, and the MAC Address of described initial data and described terminal is sent to server;
S103, receive described server send the data recovery bag carrying the MAC Address of described terminal, resolve the reply data in described data recovery bag;
S104, according to described MAC Address, described reply data are sent to described terminal by data recovery ProbeResponse.
Concrete, after what AP termination received that server sends carry the data recovery bag of the MAC Address of described terminal, parse the actual content in data recovery bag, namely reply data, after group bag, send to terminal.
Concrete, the present invention is by the expansion to WIFI agreement, just can carry out the feature of data interaction when not setting up WIFI and connecting based on WIFI management frames, by a small amount of amendment to the AP arranged net, achieve WIFI equipment can not need to set up WIFI connection, also time synchronized mustn't be done with AP, directly data are sent when needs transmission data, just super low-power consumption pattern is entered immediately after waiting for return data, wherein, under super low-power consumption pattern, the consumption of electric current drops to uA level, can use powered battery.
The method of a kind of data interaction that the embodiment of the present invention provides, comprises the request of data ProbeRequest that receiving terminal sends; Resolve the initial data in described ProbeRequest, and the MAC Address of described initial data and described terminal is sent to server; Receive the data recovery bag carrying the MAC Address of described terminal that described server sends, resolve the reply data in described data recovery bag, and according to described MAC Address, described reply data are sent to described terminal by data recovery ProbeResponse, this mode being sent data by ProbeRequest and ProbeResponse, namely the mode of data interaction is carried out by management frames, can not set up WIFI is connected at terminal and network node and carry out data interaction, achieve the super low-power consumption data interaction of WIFI equipment.
Preferably, in another embodiment of the invention, receive the ProbeRequest that described terminal sends, comprising:
Receive the ProbeRequest carrying unique identification type OUItype that described terminal sends.
Preferably, in another embodiment of the invention, receive the ProbeRequest carrying OUItype that described terminal sends, comprising:
What receive the transmission of described terminal carries the ProbeRequest that OUItype is C8-93-46.
Concrete, in order to better pick out ProbeRequest and ProbeResponse, at establishment user thread of AP end, being connected to the Cloud Server needing transmission, monitoring with OUItype the ProbeRequest of the customIE being C8-93-46.Wherein, the type of data uses 1=Station reported data, and 2=AP replys data.After the complete data of WIFI device processes, automatically can enter park mode, until need transmission data to wake up again get the hang of 1 next time.
When receiving this packet, obtaining the data data of IE immediately, then data being added that the MAC Address of WIFI equipment reports server.Send over from server the data comprising WIFI device mac address if received, just immediately the customIE of data encapsulation to be OUIType be C8-93-46, the mode with ProbeResponse sends to the WIFI equipment of this MAC Address.
Preferably, in another embodiment of the invention, also comprise: described in buffer memory, reply data;
Wherein, when receiving the next ProbeRequest that described terminal sends, described reply data are sent to described terminal.
Concrete, when for WIFI equipment to the less demanding application of the real-time property in server, the data cached mode of AP can be used to reduce the power consumption of WIFI equipment further.Specific practice is that each AP receives data from server, is first buffered in this locality, only has in time receiving the data of WIFI equipment transmission ProbeRequest, the data of buffer memory before replying immediately.WIFI equipment need not wait for the reply in high in the clouds at every turn after sending data, can again enter super low-power consumption pattern very soon.
