Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of method of transmitting data, and as shown in Figure 1, the method comprises:
101,, in terminal during to the opposite equip. transmission data file, whether the size that detects data file is less than first threshold.
Before execution step 101, whether terminal has the opposite equip. of the attachable NFC of having transmittability near need confirming.
If be less than first threshold, carry out 102, otherwise carry out 103.
102, the transmission means by NFC sends data file to opposite equip..
103, the transmission means by bluetooth or Wi-Fi sends data file to opposite equip..
Terminal described in the embodiment of the present invention and opposite equip. can be specifically the electronic equipments such as mobile phone, individual intelligent terminal, panel computer.
The actual value of first threshold, can obtain with reference to the transmission characteristic of NFC, bluetooth and tri-kinds of transmission meanss of Wi-Fi.
The characteristics of these three kinds of transmission meanss are compared as follows shown in table 1.
Table 1
Visible, NFC mode transmission rate is 106Kbps, i.e. per second 106*1024 bit, and the bluetooth approach transmission rate is a per second 2.1*1024*1024 bit, Wi-Fi mode transmission rate is per second 11*1024*1024 more than bit.
The numerical value of first threshold specifically can arrange with reference to the transmission rate of above-mentioned three kinds of transmission meanss.For instance, first threshold is set to 20KB.Be less than the data file of 20KB, by the transmission means transmission of NFC, be more than or equal to the data file of 20KB, by the transmission means transmission of bluetooth or Wi-Fi.When the transmission rate of NFC is 106Kbps, the data file of a 10KB can approximately complete transmission in 0.75 second at (10*1024*8/106*1024) second, even add, sets up the 0.1 second time that connects, total consuming time also much smaller than bluetooth and Wi-Fi transmission means, and power consumption is lower.Be more than or equal to the data file of 20KB, such as the data file of a 1MB, the mode needs (1024*1024*8/106*1024) second by NFC, approximately complete in 77 seconds, need (1024*1024*8/2.1*1024*1024) second by bluetooth approach, approximately within 3.8 seconds, complete.Visible with Bluetooth transmission or Wi-Fi transmission, consuming timely much smaller than the NFC mode, transmit.
Embodiments of the invention provide a kind of method of transmitting data, determine data file waiting for transmission in terminal, and whether the size of detection data file is less than first threshold; Send data file if be less than the transmission means of first threshold by NFC to opposite equip., if be not less than first threshold, the transmission means by bluetooth or Wi-Fi sends data file.Compared with prior art, scheme user's operation provided by the invention is simpler and easy, and selects respectively the transmission means of NFC and the transmission means of non-NFC by first threshold, and the data file that capacity is less is transmitted by NFC, avoids power consumption excessive; The data file that capacity is larger is transmitted by bluetooth or Wi-Fi, guarantees that data file is transmitted rapidly.
In another embodiment of the invention, a kind of method of transmitting data also is provided, as shown in Figure 2, comprising:
201,, in terminal during to the opposite equip. transmission data file, whether the size that detects described data file is less than first threshold.
Before execution step 201, whether terminal has the opposite equip. of the attachable NFC of having transmittability near need confirming.
If be less than first threshold, carry out 202, otherwise carry out 203.
202, the transmission means by NFC sends data file to opposite equip..
Whether the size that 203, detects described data file is less than Second Threshold.
Wherein Second Threshold is greater than first threshold.
If be less than Second Threshold, voluntarily 204, otherwise carry out 205.
204, the transmission means by bluetooth sends data file to opposite equip..
Concrete, the transmission means of passing through bluetooth in step 205, before opposite equip. transmission data file, also will be carried out following actions:
1), terminal indication opposite equip. is opened Bluetooth function.
2), terminal and opposite equip. transmit the bluetooth key.
Optionally, terminal can be opened Bluetooth function by the interactive mode indication opposite equip. of NFC, and transmits the bluetooth key.
205, the transmission means by Wi-Fi sends data file to opposite equip..
Concrete, the transmission means of passing through bluetooth in step 206, before opposite equip. transmission data file, also will be carried out following actions:
1), terminal indicates described opposite equip. to open the Wi-Fi function.
2), terminal is transmitted the Wi-Fi key to opposite equip..
Optionally, terminal can be opened the Wi-Fi function and transmit the Wi-Fi key by the interactive mode indication opposite equip. of NFC.
Open Wi-Fi function (or Bluetooth function) and transmit Wi-Fi key (or bluetooth key) by NFC interactive mode indication opposite equip., having realized terminal room Wi-Fi(or bluetooth) certainly be dynamically connected, avoid the user manually to be connected, save the connect hours.
With reference to above-mentioned table 1, NFC mode transmission rate is 106Kbps, i.e. per second 106*1024 bit, and the bluetooth approach transmission rate is a per second 2.1*1024*1024 bit, Wi-Fi mode transmission rate is per second 11*1024*1024 more than bit.
For first threshold, for instance, first threshold is set to 20KB.Be less than the data file of 20KB, by the transmission means transmission of NFC, be more than or equal to the data file of 20KB, by the transmission means transmission of bluetooth or Wi-Fi.When the transmission rate of NFC is 106Kbps, the data file of a 10KB can, at (50*1024*8/106*1024) second, approximately complete transmission in 3.7 seconds, even add the 0.1 second time of connecting, total consuming time also much smaller than the transmission means of bluetooth or Wi-Fi, and power consumption is lower.Be more than or equal to the data file of 50KB, data file such as a 100KB, mode by NFC needs (100*1024*8/106*1024) second, approximately within 7.5 seconds, complete, by bluetooth approach, need (100*1024*8/2.1*1024*1024) second, approximately within 0.37 second, complete, even if suppose the approximately 6 seconds time of connecting, total NFC mode that also is less than consuming time, and along with data file is increasing, consuming time the comparing with NFC of Bluetooth transmission can be more and more less.
When data file further becomes large, need to judge whether its size is less than Second Threshold.For instance, Second Threshold is set to 5MB, is less than the data file of 5MB by Bluetooth transmission, and the data file that is more than or equal to 5MB is transmitted by Wi-Fi.Such as the data file of a 1MB, Bluetooth transmission needs (1*1024*1024*8/2.1*1024*1024) second, approximately within 3.8 seconds, complete, and not obviously difference of used time and Wi-Fi transmission, but power consumption is less.If the data file of a 20MB needs (20*1024*1024*8/2.1*1024*1024) second by Bluetooth transmission, approximately within 76 seconds, complete; Need (20*1024*1024*8/11*1024*1024) second with the Wi-Fi transmission, approximately 14 seconds, now the Wi-Fi transmission used time should be selected the transmission means of Wi-Fi much smaller than the Bluetooth transmission used time as seen.
In above-mentioned example, the numerical value of first threshold and Second Threshold is for describing for example, for illustrating by detecting the magnitude relationship of data file and first threshold, Second Threshold, select different modes to carry out transfer of data, the value of first threshold and Second Threshold does not form the restriction of the embodiment of the present invention.In practical application, those skilled in the art can obtain two spans by the experiment of limited number of times, in first span, chooses first threshold, in second span, chooses Second Threshold.
