Figure 1A means that a Wi-Fi device is used the biography of AFH spread spectrum (AFHSS) technology under three kinds of different situations to receive data traffic.At first please refer to Figure 1A, when the 1st kind of situation in Figure 1A (being cylindricality Figure 111,112 that in Figure 1A, transverse axis is denoted as 1 top) received data for described Wi-Fi device is used the AFHSS transmission mode to pass, the bluetooth mouse that the Wi-Fi device coexists therewith is not linked to the electronic installation of embedded Wi-Fi device of while and blue-tooth device, and bluetooth mouse is disabled (disabled).When the 2nd kind of situation in Figure 1A (being cylindricality Figure 113,114 that in Figure 1A, transverse axis is denoted as 2 tops) received data for described Wi-Fi device is used the AFHSS transmission mode to pass, the bluetooth mouse that the Wi-Fi device coexists therewith has been linked to the electronic installation of embedded Wi-Fi device and blue-tooth device, but the bluetooth mouse transfixion.In Figure 1A, the percent value shown in cylindricality Figure 111,112 tops is 0%, because the benchmark that cylindricality Figure 111,112 is other two situations.Percent value 1% and-1% in Figure 1A shown in cylindricality Figure 113,114 tops represents that respectively the transmission data traffic of Wi-Fi device increases by 1%, and the receiving data stream flux of Wi-Fi device reduces by 1%.
When the 3rd kind of situation in Figure 1A (being cylindricality Figure 115,116 that in Figure 1A, transverse axis is denoted as 3 tops) received data for described Wi-Fi device is used the AFHSS transmission mode to pass, the bluetooth mouse that the Wi-Fi device coexists therewith has been linked to the electronic installation of embedded Wi-Fi device and blue-tooth device, and user's ongoing operation (or mobile) bluetooth mouse.Therefore, bluetooth mouse and the transfer of data between electronic installation in the 3rd kind of situation can be more frequent.In Figure 1A, the percent value shown in cylindricality Figure 115,116 tops represents for-1% and 0% that respectively the transmission data traffic of Wi-Fi device reduces by 1%, and the receiving data stream flux of Wi-Fi device does not change.
Figure 1B means that a Wi-Fi device is used the biography of time-division multiplex (MUX) (TDM) technology under three kinds of different situations to receive data traffic.Please refer to Figure 1B, when the 1st kind of situation in Figure 1B (being cylindricality Figure 121,122 that in Figure 1B, transverse axis is denoted as 1 top) received data for described Wi-Fi device is used the TDM transmission mode to pass, the bluetooth mouse that the Wi-Fi device coexists therewith is not linked to the electronic installation of embedded Wi-Fi device and blue-tooth device, and bluetooth mouse is disabled (disabled).In Figure 1B, the percent value shown in cylindricality Figure 121,122 tops is 0%, because the benchmark that this cylindricality Figure 121,122 is other two situations.
When the 2nd kind of situation in Figure 1B (being cylindricality Figure 123,124 that in Figure 1B, transverse axis is denoted as 2 tops) received data for described Wi-Fi device is used the TDM transmission mode to pass, the bluetooth mouse that the Wi-Fi device coexists therewith has been linked to the electronic installation of embedded Wi-Fi device and blue-tooth device, but the bluetooth mouse transfixion.In Figure 1B, the percent value-6% shown in cylindricality Figure 123,124 tops and-4% represents that respectively the transmission data traffic of Wi-Fi device reduces by 6%, and the receiving data stream flux of Wi-Fi device reduces by 4%.
When the 3rd kind of situation in Figure 1B (being cylindricality Figure 125,126 that in Figure 1B, transverse axis is denoted as 3 tops) received data for described Wi-Fi device is used the TDM transmission mode to pass, the bluetooth mouse that the Wi-Fi device coexists therewith has been linked to the electronic installation of embedded Wi-Fi device and blue-tooth device, and user's ongoing operation (or mobile) bluetooth mouse.Therefore, bluetooth mouse and the transfer of data between electronic installation in the 3rd kind of situation can be more frequent.In Figure 1B, the percent value shown in cylindricality Figure 125,126 tops represents for-20% and-28% that respectively the transmission data traffic of Wi-Fi device reduces by 20%, and the receiving data stream flux of Wi-Fi device reduces by 28%.
Can find that by comparing Figure 1A and Figure 1B the transmission of Wi-Fi device is under the TDM transmission mode, when blue-tooth device has transfer of data, the problem that data traffic reduces of receiving that passes obviously be arranged.Especially when blue-tooth device constantly carries out transfer of data with electronic installation, the situation that the biography of Wi-Fi device is received the data traffic reduction is more serious.Therefore, the experimental result (Figure 1A and Figure 1B) presented according to above-mentioned these two charts, the method of can finding out is improved the embedded Wi-Fi module of current electronic installation and the problem that interferes with each other that bluetooth module coexists while operating, and further promotes user's experience.Below Fig. 2 to Fig. 4 is introduced to the data transmission method that causes the many communications protocol of the present invention, and introduce the data transmission device of many communications protocol with Fig. 5.
Referring to Fig. 2 and Fig. 5, Fig. 2 is the flow chart according to the data transmission method 200 of first a kind of many communications protocol that example embodiment illustrates of the present invention, and Fig. 5 is the system block diagrams that an example embodiment according to the present invention illustrates a kind of electronic installation 500 of the data transmission device with many communications protocol.In this example embodiment, described method 200 is started by step 201, at first in step S201, identify the setting configuration file that the first communications protocol is used at present, and the setting configuration file used at present according to the first communications protocol selects the first communications protocol and the second communications protocol to use frequency-hopping spread spectrum transmission mode or multiplex's transmission mode simultaneously.
In this example embodiment, the setting configuration file that the first communications protocol is used at present can be for example that human interface arrangement host-host protocol (HID) is set configuration file, or Bluetooth stereo audio transmission agreement is set configuration file (A2DP).When setting the current setting configuration file used of configuration file recognition unit 531 identification the first communications protocol, be that a high-transmission amount (is for example set configuration file, A2DP sets configuration file) time, transmission mode selection unit 532 selects the first communications protocol and the second communications protocol to use multiplex's transmission mode simultaneously.Because the high-transmission amount is set configuration file, (for example, blue-tooth device is set configuration file with A2DP and passed the real-time speech data of receipts) needs higher message transmission rate, uses multiplex's transmission mode can guarantee that the user experiences preferably demand.The volume of transmitted data pattern of the second communications protocol (for example, the Wi-Fi device carries out simple transmission data) is for than burst (bursty), and under multiplex's transmission mode, being difficult for allowing the user discover has obvious operational paradigm to reduce.On the contrary, when setting configuration file recognition unit 531 identification setting configuration files, be that the throughput rate of passing at the low (is for example set configuration file, HID sets configuration file) time, transmission mode selection unit 532 selects the first communications protocol and the second communications protocol to use the frequency-hopping spread spectrum transmission mode simultaneously, for example, to maintain the transport stream flux of the second communications protocol (, the Wi-Fi device carries out simple transmission data).
Step S201 can be divided into step S202, S204 and S206 again.In step S202, set the setting configuration file of configuration file recognition unit 531 identification the first communications protocol uses at present and set configuration file for pass at the low throughput rate setting configuration file or high-transmission amount.Set configuration file if set configuration file for the throughput rate of passing at the low, then perform step S206; On the contrary, if set configuration file, be that the high-transmission amount is set configuration file, then perform step S204.In step S204, transmission mode selection unit 532 selects the first communications protocol and the second communications protocol to use multiplex's transmission mode simultaneously.After step S204, finish the data transmission method 200 of whole many communications protocol.In step S206, transmission mode selection unit 532 selects the first communications protocol and the second communications protocol to use the frequency-hopping spread spectrum transmission mode simultaneously.After step S206, perform step S208.
Give an example again to further illustrate the thin section action of the step S201 of described method 200.While supposing that the user comparatively payes attention to for user's experience of bluetooth equipment real-time, for example: the user is using bluetooth earphone, the setting configuration file of its use is set configuration file for A2DP, with reach 48 KHz (referred to as kHz) and data the palpus transmission rate surpass about 921 per second kilobits (referred to as kbps).Described method 200 can be perceived the first communications protocol and use the high-transmission amount to set configuration file, so method 200 selects the first communications protocol and the second communications protocol to use multiplex's transmission mode simultaneously, stablize real-time and serve required transmission rate or transport stream flux to maintain, and then keep good user to experience.Therefore, the user hears that the real-time sound of (receiving terminal that is relative electronic installation) not there will be desultory audio quality.
In addition, at this, be noted that the frequency-hopping spread spectrum transmission mode can be AFH spread spectrum transmission pattern, and multiplex's transmission mode can be time-division multiplex (MUX) pattern, code minute multiplex's pattern or self adaptation time-division multiplex's pattern.In addition, in this example embodiment, when the first communications protocol and the second communications protocol are used described multiplex's transmission mode simultaneously, the second medium access control layer that the data that the tendency to develop of the first communications protocol institute can be sent are handed to the second communications protocol from the first medium access control layer of the first communications protocol is processed, then transmit by the physical layer of the second communications protocol.
Then, in step S208, transport stream flux detecting unit 533 detects the current transport stream flux of the first communications protocol.After step S208, continue to carry out step S210.In step S210, transport stream flux comparing unit 534 judges whether the current transport stream flux of the first communications protocol is greater than a transport stream flux threshold value.In this example embodiment, transport stream flux threshold value is for example 1 megabits per second (referred to as Mbps).But the present invention is not limited thereto, can also select suitable transport stream flux threshold value according to actual needs.In addition, described transport stream flux account form needs the observation and collection related streams flux data of certain hour, for example, so may also need to be limited in a circulation data statistics time or circulation data statistics cycle (, 20 seconds), have calculated.But the present invention is not limited thereto, can also select the suitable circulation data statistics time according to actual needs.If the current transport stream flux of the first communications protocol is greater than a transport stream flux threshold value,, after step S210, continue to carry out step S204.If the current transport stream flux of the first communications protocol is not greater than a transport stream flux threshold value,, after step S210, then carry out step S212.
In step S212, transmission rate detecting unit 535 detects the current transmission rate of the first communications protocol.After step S212, then carry out step S214.In step S214, transmission rate comparing unit 536 judges whether the current transmission rate value of the first communications protocol is greater than a transmission rate threshold value.In this example embodiment, the transmission rate threshold value is for example the arbitrary value of 500kbps to 1Mbps.But the present invention is not limited thereto, can also select suitable transmission rate threshold value according to actual needs.If the current transmission rate value of the first communications protocol is greater than a transmission rate threshold value,, after step S214, continue to carry out step S204.If the current transmission rate value of the first communications protocol is not greater than a transmission rate threshold value,, after step S214, finish the data transmission method 200 of whole many communications protocol.
Be noted that step S208, S210 can exchange order with step S212, S214.In other words, the order of each step of Fig. 2 is not in order to limit the present invention.In addition, step S208, S210, S212, S214 can also remove.Although add that the data transmission method 200 of step S208, S210, S212, S214 is is the throughput rate setting configuration file of passing at the low in order to ensure the user at the setting configuration file of the first communications protocol,, still can have and preferably experience impression in the situation of throughput rate but its transmission quantity is not passed at the low.In addition, in this example embodiment, the first communications protocol can also be bluetooth communication agreement, a kind of near radio transmission communication agreement or a kind of wireless personal network communications protocol.The second communications protocol can be IEEE 802.11 communications protocol, a kind of WLAN communications protocol or a kind of wireless fidelity communications protocol (Wi-Fi).
Fig. 3 is the flow chart according to the data transmission method 300 of second another kind of many communications protocol that example embodiment illustrates of the present invention.Referring to Fig. 3 and Fig. 5, in this example embodiment, described method 300 is similar haply with method 200, both differences are the first comparative result with corresponding transport stream flux threshold value according to the current transport stream flux of the first communications protocol of method 300, the transmission mode of selecting the first communications protocol and the second communications protocol simultaneously to use.In this example embodiment, described method 300 is started by step S301, at first in step S301, detect the current transport stream flux of the first communications protocol, and, according to the current transport stream flux of the first communications protocol, select the first communications protocol and the second communications protocol to use frequency-hopping spread spectrum transmission mode or multiplex's transmission mode simultaneously.
Step S301 can be divided into step S302, S304, S306 and S308 again.In step S302, transport stream flux detecting unit 533 detects the current transport stream flux of the first communication.After step S302, proceed step S304.In step S304, transport stream flux comparing unit 534 judges whether the current transport stream flux of the first communications protocol is greater than a transport stream flux threshold value.In this example embodiment, transport stream flux threshold value is for example 1Mbps.But the present invention is not limited thereto, can also select suitable transport stream flux threshold value according to actual needs.If the current transport stream flux of the first communications protocol is greater than a transport stream flux threshold value,, after step S304, continue to carry out step S306; On the contrary, if the current transport stream flux of the first communications protocol is not greater than a transport stream flux threshold value,, after step S304, carry out step S308.In step S306, transmission mode selection unit 532 selects the first communications protocol and the second communications protocol to use multiplex's transmission mode simultaneously.After step S306, finish the data transmission method 300 of whole many communications protocol.In step S308, transmission mode selection unit 532 selects the first communications protocol and the second communications protocol to use the frequency-hopping spread spectrum transmission mode simultaneously.After step S308, perform step S310.
Then, in step S310, set the setting configuration file of configuration file recognition unit 531 identification the first communications protocol uses at present and set configuration file for pass at the low throughput rate setting configuration file or high-transmission amount.Set configuration file if set configuration file for the throughput rate of passing at the low, then perform step S312; On the contrary, if set configuration file, be that the high-transmission amount is set configuration file, continue to carry out step S306.In step S312, transmission rate detecting unit 535 detects the current transmission rate of the first communications protocol.After step S312, continue to carry out step S314.In step S314, transmission rate comparing unit 536 judges whether the current transmission rate value of the first communications protocol is greater than a transmission rate threshold value.In this example embodiment, the transmission rate threshold value is for example the arbitrary value of 500kbps to 1Mbps.But the present invention is not limited thereto, can also select suitable transmission rate threshold value according to actual needs.If the current transmission rate value of the first communications protocol is greater than a transmission rate threshold value,, after step S314, continue to carry out step S306; On the contrary, if the current transmission rate value of the first communications protocol is not greater than a transmission rate threshold value,, after step S314, finish the data transmission method 300 of whole many communications protocol.
