NDEF message or NFC frames are made of several records (Record), and as shown in figure 11, each record format is as shown in figure 12,
Wherein, MB indicates that the record is first record in the frame, and ME indicates that the record is that the last one in the frame records, and CF is block
Mark instruction.SR indicates that payload length field is 1 byte if SR=1, is otherwise 4 bytes for short record.IL is indicated
It is Message Payload type whether to have ID length fields, TNF.
There are three types of frame types altogether by WIFI：Data frame, control frame and management frame.Wherein data frame is divided into the data for carrying data
Frame and the data frame for not carrying data.In the present embodiment, NFC frames are encapsulated in the data frame for carrying data, therefore omit other
The discussion of frame.In addition, data frame concrete form is related with latticed form, different type format is different, for simplicity, will carry
The data frame of data is reduced to general format as shown in fig. 13 that.
Since WIFI maximum load of data frame is 2312 bytes, and a NDEF record length may be far more than its maximum
Load, is responsible for assembling after transmission success according to WIFI fragment rule fragments by NFC at this time.
It is as shown in figure 14 that NFC frames are encapsulated in the structure after WIFI data frames.
As shown in figure 15, in the present embodiment, WIFI coding implementation processes may include：
NFC applications send out request；
NFC system service receives the request that application is sent out and forwards the request to NFC drivings；
Request data is packaged into NFC frames by NFC drivings, but different from the realization of existing NFC technique, and NFC drivings should not
Frame is sent to radio-frequency module, but is transmitted to WIFI drive modules；
NFC frames are packaged into WIFI frames and are sent out by WIFI chips by WIFI drive modules.
In the present embodiment, correspondingly, as shown in figure 16, WIFI decodings implementation process may include：
WIFI drivings receive the data from radio frequency and are parsed into WIFI frames；
WIFI drivings decapsulate NFC frames from WIFI data frames and are given to NFC drivings；
NFC drivings decapsulate NFC data from the NFC frames and are given to NFC system service；Divide if NFC data exists
Piece, NFC drivings are responsible for assembling fragment and verify integrality, if it is successful, being submitted to NFC system service；
The NFC data is submitted to corresponding NFC and applied by NFC system service.
The embodiment of the present invention is extended NFC payment distance using WIFI signal, can ensure existing NFC closely
It is eliminated while payment safety and closely pays the inconvenience brought.Traditional method is compared, mainly there is following advantageous effect：
It eliminates NFC and closely pays the limitation that can only be carried out in 2~20 centimetres, 2~200 meters of models can be expanded to
It encloses, to improve convenience and the flexibility of payment；
Using the WIFI network of existing widespread deployment, it is not required to redeploy network, saves network lower deployment cost；
It only needs to do software modification to NFC mobile terminal and POS machine, there is no hardware modification cost.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the scope of the present invention.
