Main thought of the present invention is, before transmission data (data to be transmitted), by in the transmission means mutually supported at transmitting terminal and receiving terminal, determine that often kind of transmission means is when transmitting these data, the required transmission time, according to the transmission time of often kind of transmission means, determine the transmission means transmitting these data.Such as, use transmission time the shortest transmission means to transmit data, or use save time and easily transmission means to transmit data.Effectively can improve message transmission rate by the present invention, promote Consumer's Experience effect.
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
According to embodiments of the invention, provide a kind of data transmission method.As shown in Figure 1, Fig. 1 is the flow chart of data transmission method according to an embodiment of the invention.
Step S110, determines the transmission means that transmitting terminal and receiving terminal are all supported.
Transmitting terminal and receiving terminal are all terminal.As, mobile terminal.
Transmission means includes but not limited to: NFC mode, WiFi mode and bluetooth approach.
Specifically, transmitting terminal, before sending data to receiving terminal, needs to find/scanning/search receiving terminal; When the discovery/scanning/search of receiving terminal response transmitting terminal, transmitting terminal can obtain communication protocol and the messaging parameter of receiving terminal use; Transmitting terminal, by analyzing this communication protocol, can know the transmission means that transmitting terminal and receiving terminal are all supported.
Step S120, calculated based on the transmission time required during often kind of transmission means transmission data.
All following steps are performed: know one or more transmission rates that transmitting terminal and receiving terminal are all supported for often kind of transmission means; Determine the peak transfer rate in one or more transmission rates; According to the data volume of this peak transfer rate and data, the transmission time required when calculating transmission data.
Specifically, the messaging parameter that transmitting terminal uses by analyzing receiving terminal, can know in often kind of transmission means, one or more transmission rates that transmitting terminal and receiving terminal are all supported; For often kind of transmission means, transmitting terminal and receiving terminal mode through consultation, in the transmission rate that transmitting terminal and receiving terminal are all supported, selects the transmission rate that numerical value is maximum, as peak transfer rate.
Such as: transmitting terminal sends to the radiofrequency field around it request of discovery; Receiving terminal responds this discovery request, and in response signal, carry its communication protocol used and messaging parameter; Transmitting terminal, by analyzing communication protocol and the messaging parameter of receiving terminal use, learns that transmitting terminal and receiving terminal all support NFC mode and the transmission rate that the NFC mode of receiving terminal is supported comprises: 212kbps, 424kbps and 848kbps; Transmitting terminal learns that the transmission rate that the NFC mode of self is supported comprises: after 106kbps, 212kbps and 424kbps, transmitting terminal and receiving terminal are held consultation, in 212kbps and 424kbps that transmitting terminal and receiving terminal are all supported, determine 424kbps as peak transfer rate.
Step S130, in the transmission time corresponding according to often kind of transmission means, selects the transmission means of the described data of transmission.
According to the transmission time required during often kind of transmission means transmission data, select a kind of transmission means of the best, transmit described data.
Preferably, in all transmission meanss that transmitting terminal and receiving terminal are all supported, the transmission time that all transmission meanss being transmitted described data needs compares the present embodiment; In multiple transmission means, select the transmission means that the transmission time is the shortest, after sending end pending and receiving terminal connect based on this transmission means, transmit this data.
Such as: in all transmission meanss, the transmission time of NFC mode is the shortest, then choice for use NFC mode transmits data, and to set up after network is connected based on NFC technique at transmitting terminal and receiving terminal, transmitting terminal sends data to receiving terminal.
By the transmission means transmission data selecting the transmission time the shortest, effectively can shorten the transmission time, improve data transmission efficiency, promote Consumer's Experience effect, the data simultaneously avoiding big data quantity use the transmission means that transmission rate is low, and the problem that the power consumption caused is excessive.
Step S140, based on the described transmission means selected, transmits described data.
On the basis of improving message transmission rate, in order to promote Consumer's Experience effect further, determining to transmit in the transmission means of data, The present invention gives the embodiment that can be reduced data operation quantity.In the present embodiment, the transmission means that transmitting terminal and receiving terminal are all supported comprises NFC mode.
As shown in Figure 2, Fig. 2 is the flow chart of steps determining data transfer mode according to an embodiment of the invention.
Step S210, the transmission time needed when determining often kind of transmission means transmission data.
Step S220, judges whether transmission time corresponding to NFC mode is less than the time threshold pre-set.If so, then step S230 is performed; If not, then step S240 is performed.
Time threshold is that the power consumption needed for data is chosen according to Consumer's Experience and transmission.Preferably, time threshold is 5s to the present embodiment.
Specifically, because NFC is near-field communication technology, when only having the close together of transmitting terminal and receiving terminal, communicating of transmitting terminal and receiving terminal could be realized, further, in the process of carrying out transfer of data, transmitting terminal and receiving terminal cannot leave the radiofrequency field scope of the other side.So, in order to avoid the inconvenience that transmitting terminal and receiving terminal keep closer distance to bring always, so, when only having that the transmission time, data volume that is shorter, data was less, just adopt NFC mode, transmission time is short means that transmitting terminal contacts without the need to keeping long with receiving terminal, and required power consumption that data volume is little when meaning transmission is less.Like this, when adopting the present embodiment to transmit data, transmit data according to NFC mode, then transmitting terminal and receiving terminal only need contact the shorter time, just can complete the transmission of data.
Step S230, adopts NFC mode to transmit data.
Step S240, in other transmission meanss that transmitting terminal and receiving terminal are all supported, selects the transmission means that the transmission time is the shortest, transmits data.
If the time of transmission data is more than or equal to time threshold, as 5s, then do not use NFC mode to transmit as far as possible, but, when using other transmission meanss, need to choose transmission time the shortest transmission means, such as, in WiFi mode and bluetooth approach, the transmission time of WiFi mode is T
w, the transmission time of bluetooth approach is T
bif, T
w< T
b, then select the WiFi mode that the transmission time is the shortest, transmit data.Like this, while improving Consumer's Experience effect, can also guarantee that message transmission rate increases.
It should be noted that, in the present embodiment, the transmission time whether transmission time for NFC mode is less than other transmission meanss does not limit.
In yet another embodiment of the present invention, when determining the transmission means transmitting data, first can also calculate the transmission time that NFC mode transmits described data, if transmission time corresponding to NFC mode is less than time threshold, NFC mode is then adopted to transmit data, if transmission time corresponding to NFC mode is more than or equal to time threshold, then calculate the transmission time that other transmission meanss transmit described data, the transmission means adopting the transmission time the shortest transmits data.This embodiment can reduce the operand of data.
