Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, is not whole embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

Effective initial data is more, and to improving, call tone quality is more helpful, so waste mentioned above is reduced, The method of reduction is exactly the sco data provided by controller and the anti-data and mark for releasing aerial sco data packet of mark.

As shown in fig.3, providing a kind of processing method of Baffle Box of Bluetooth call tone quality in present invention implementation, detailed process is such as Shown in lower:

Step 300: after receiving voice data to be processed, blue-tooth device reads p m byte from the voice data VoP, and according to the size and number p of the VoP of reading and the voice data of preset air transmission The size of packet determines the quantity q of the VoP of current air transmission, and wherein the size of the VoP of air transmission is N byte, p, m, n are the positive integer of setting, and m < n.

Specifically, blue-tooth device reads p m byte from the voice data after receiving voice data to be processed Voice data VoP, and according to the size and number p of the VoP of reading and preset air transmission The size of VoP determines the quantity q of the VoP of current air transmission, wherein the voice number of current air transmission It is equal to blue-tooth device according to the size that the quantity q of packet meets all VoPs of current air transmission to read from the voice data The size of all VoPs taken, i.e. p*m=q*n.

Specifically, the status indicator of the VoP read from the voice data includes first identifier, the second mark Knowledge, third mark and the 4th mark, wherein first identifier indicates that the VoP receives correct data, and second identifier refers to Show that the VoP receives the data of mistake, third mark indicates that the VoP is not received by any data, the Four marks indicate that the VoP receives partial data；

The status indicator of the VoP of air transmission includes first identifier, second identifier and third mark, wherein the One mark indicates that the VoP verification of the air transmission is correct, and second identifier indicates the VoP verification of air transmission Mistake, the voice data packet loss of third mark instruction air transmission；

For example, the VoP mark 0 that receiving end receives in the embodiment of the present invention indicates to receive correct number Pass through according to receiving the data in the air and verifying；Mark 1 indicates at least one i.e. corresponding aerial sco packet of data that may be wrong The data check received does not pass through；Mark 2 indicates that no data receive and i.e. corresponding occur the case where packet loss in the air；Mark 3 table It existing partial data is shown loses also having for i.e. corresponding aerial sco Bao Zhongyou packet loss and be properly received.Specifically, receiving end receives Status indicator to VoP is seen shown in table 1.

Table 1

Aerial VoP only has 0,1,2 three kind of mark, and mark 0 indicates that the data of transmission are correct；Mark 1 indicates to pass Defeated data are wrong；Mark 2 indicates the loss of data of transmission, i.e., aerial packet loss, and the mark without part packet loss (is marked Will 3).Specifically, the status indicator of the VoP of air transmission is seen shown in table 2.

Table 2

Further, after receiving voice data to be processed, blue-tooth device is periodically read from the voice data The VoP of p m byte is taken, which is the third mark of x byte since first voice data The initialization voice data of knowledge, remaining voice data are the voice data from air transmission, and wherein the voice data of x byte is complete Portion is 0, and x < w, w are the byte number of voice data to be processed.

Reason for this is that control terminal (Controller) under normal circumstances start to send after sco link establishment data to Main control end (host) has just started be that the initialization voice data that a segment mark is 2 fades in quiet data, usually tens millis Second to several hundred milliseconds, followed by normal voice data.In the mark of the end host detection sco packet, when finding it is not 2, lead to It crosses and calculates the number of 0 data that sco packet of this non-2 mark most starts and can determine the starting aligned position of voice data, this As long as being due to there is packet loss in the air, all voice data clear 0 can be given host by corresponding controller, and speech silence The value of data is usually -1, is not 0.

Step 301: successively obtaining the data and status indicator that each VoP of reading carries, and tied according to obtaining Fruit determines the first position of voice data, determines processing initial position according to the first position.

Specifically, successively obtaining the data and status indicator that each VoP of reading carries, and tied according to obtaining Fruit determines the first position of voice data, determines processing initial position, detailed process according to the first position are as follows: successively obtain and read The data and status indicator that each VoP taken carries, data and state mark based on each data packet got Know, there is status indicator not and is the position of the VoP of third mark as first position for the first time in record, and statistics from The number y for 0 data that the packet header of VoP where the first position is continuously acquired to first position, judges y's Whether size is 0, if so, first VoP that the period 1 is read as processing initial position, otherwise, calculates I=((y*p)/m)+1, the position after counting p-i VoPs again since first position are used as processing initial position, Wherein (y*p)/m is that (y*p) is rounded divided by m.

Step 302: since the processing initial position, within each period, p are read from received voice data VoP, and according to the data and status indicator of the carrying of p VoP of reading, determine corresponding air transmission The data and status indicator that each VoP carries, and the data that each VoP based on air transmission carries And status indicator, processing is compensated to voice data received in current period.

Specifically, within each period, p are read from received voice data since the processing initial position VoP, and according to the data and status indicator of the carrying of p VoP of reading, determine corresponding air transmission The data and status indicator that each VoP carries, including two kinds of situations:

The first situation are as follows: when determining that p is greater than q and is less than 2q, since the processing initial position, in each period It is interior, p VoP is read from received voice data, by the q voice number of the p VoP and air transmission Registration process is carried out according to packet, each voice data of air transmission is determined according to the data that p VoP of reading carries The data carried, and the status indicator of first VoP according to reading are wrapped, determine first language of air transmission The status indicator of sound data packet；According to the status indicator of the first of air transmission VoP, p voice data of reading The data that the status indicator of packet and each VoP of air transmission carry, determine each voice of corresponding air transmission The status indicator of data packet, wherein the status indicator of the first of air transmission VoP and read first voice number It is identical according to the status indicator of packet.

Doing so, which can make the VoP of air transmission terminate the VoP received with host, is aligned, from And the voice data of air transmission is obtained, wherein the voice data of air transmission terminates the voice number received with the host after being aligned According to identical.

Specifically, according to the status indicator of the first of air transmission VoP, p VoP of reading The data that each VoP of status indicator and air transmission carries, determine each voice data of corresponding air transmission The status indicator of packet, detailed process are as follows: when the status indicator of the VoP transmitted in the sky is not second identifier, root According to the status indicator of next VoP of corresponding reading, the state of next VoP of air transmission is determined Mark, and establish the shape of the status indicator of next voice school bag of air transmission and a VoP of the air transmission State mark, read next VoP status indicator between the first mapping relations；Determining the of air transmission When the status indicator of one VoP is not second identifier, according to the state mark of the first of air transmission VoP The status indicator of knowledge and second VoP read, second voice of air transmission is determined using the first mapping relations The status indicator of data packet；When the status indicator for first VoP for determining air transmission is second identifier, according to The state of the third VoP of data and reading that second VoP of air transmission carries determines aerial pass The status indicator of second defeated VoP；Continue the status indicator of a VoP according to air transmission, read The data of next VoP carrying of the status indicator and air transmission of the next VoP taken determine in the air The status indicator of next VoP of transmission, the state mark of each VoP until determining air transmission Until knowledge.

For example, as shown in fig.4, the status indicator and the first of reading of first VoP due to air transmission The status indicator of a VoP is identical, and wherein the VoP of air transmission is indicated with air_pkti, the language received Sound data are indicated with uart_pkti, if the mark of air_pkt1 is not 1, it is assumed that air_pkt1=0, i.e., correct data, at this time Uart_pkt1=0 can release air_pkt2=0 as uart_pkt2=0, this is because the voice data of uart_pkt2 It is partially contained in air_pkt2, if the data that uart_pkt2 is the corresponding air_pkt2 of correct data are also correctly to transmit 's；Similarly air_pkt1=0, as uart_pkt2=1, air_pkt2=1；Similarly air_pkt1=0 works as uart_pkt2= When 3, air_pkt2=2；Notice that the mark of uart_pkt2 when air_pkt1=0 can not be equal to 2, because in air_pkt1 Included part valid data.If air_pkt1=2, as uart_pkt2=1, air_pkt2=1；Work as air_pkt1 When=2, uart_pkt2=2, air_pkt2=2；Work as air_pkt1=2, when uart_pkt2=3, air_pkt2=0；Pay attention to The mark of uart_pkt2 can not be equal to 0 when air_pkt1=2, because it has had partial data loss.The above conversion can be with It is abstracted as following mapping table, is specifically shown in Table 3.

Table 3

Specifically, when the status indicator for first VoP for determining air transmission is second identifier, according to sky The state of the third VoP of data and reading that second VoP of middle transmission carries, determines air transmission Second VoP status indicator, detailed process are as follows: in the shape for first VoP for determining air transmission State mark obtains the data that second VoP of air transmission carries when being second identifier, judges the of air transmission Whether the data that two VoPs carry are all 0, if so, determining the state of second VoP of air transmission It is identified as third mark；Otherwise, whether the status indicator for further judging the third VoP read is second identifier, If so, the status indicator for determining second VoP of air transmission is second identifier；Otherwise, it is determined that air transmission The status indicator of second VoP is first identifier.

For example, as shown in fig.4, assuming air_pkt1=1, i.e. the data of air transmission are wrong, at this time uart_pkt2 Certainly it is 1, can not instead releases the mark of air_pkt2 by the mark of air_pkt1 and uart_pkt2 using mapping table, Whether the value that can first detect the data of air_pkt2 at this time is all 0, if being all 0, air_pkt2=2；Otherwise, continue to obtain The Status Flag for taking uart_pkt3, works as uart_pkt3！When=1, air_pkt2=0；As uart_pkt3=1, air_pkt2 =1, this way by introduce air_pkt2 originally and be 0 it is misjudged at 1 possibility, i.e. air_pkt1=1, air_pkt2=1, this When detection air_pkt2 the values of data be not the case where being all likely to occur air_pkt2=0 as uart_pkt3=1 for 0, But its really it is counter push away before, the mark of uart_pkt2 and uart_pkt3 have been 1, so we really judge air_pkt2 by accident It there will not be adverse effect for 1, do not achieve the purpose that optimization only.

Second case are as follows: when determining p not less than 2q, since the processing initial position, within each period, from connecing In the voice data of receipts read p VoP, by q VoP of the p VoP and air transmission into Row registration process determines that each VoP of air transmission carries according to the data that p VoP of reading carries Data；The status indicator for obtaining the p VoP read, determines the state mark of each VoP of air transmission Know, wherein the status indicator phase of the status indicator of i-th of VoP of air transmission and a-th of the VoP read Together, a=(p*i/q), a take positive integer, and i is the positive integer greater than 0 and no more than q.

For example, as shown in fig.5, for p be greater than 2q situation, air_pkt (i)=uart_pkt ((p/q) * i), wherein I is the positive integer greater than 0 and less than or equal to p, and p is the packet number in uart_pkt a cycle, and m is the size of uart_pkt, q It is the packet number in air_pkt a cycle, n is the size of air_pkt, and p/q is that p is rounded divided by q.

Specifically, data and status indicator that each VoP based on air transmission carries, in current period Interior received voice data compensates processing, detailed process are as follows: if the status indicator of a VoP of air transmission When being identified for third, the voice data that a VoP is corresponded in the received voice data of current period is mended Repay processing.

Embodiment one corresponds to host termination with the VoP of 60 byte of air transmission (air) and receives 48 byte voices Data packet carries out the analyzing examples above method.

Embodiment one

First have to ask their minimum according to the sco packet size that the sco packet size and controller of air transmission export Common multiple, as shown in fig. 6,48 and 60 least common multiple is 240, i.e., uart interface in the end host often receives corresponding when 5 sco packets 4 sco packets of air transmission.

The end host is respectively indicated with uart_pkt1, uart_pkt2, uart_pkt3, uart_pkt4, uart_pkt5 to receive First to the 5th sco data packet in some period arrived, air_pkt1, air_pkt2, air_pkt3, air_pkt4 difference Indicate first to fourth sco data packet of corresponding air transmission.

Further, confirm the starting aligned position of voice data.Controller is in sco link establishment under normal circumstances After start to send data to host, just started be initialization voice data that a segment mark is 2, usually a few tens of milliseconds is to several hundred Millisecond, followed by normal data.In the mark of the end host detection sco packet, when finding it is not 2, this non-2 mark is calculated The number of 0 data that most starts of sco packet, as long as it should be noted that occur packet loss in the air, corresponding controller can will All data clear 0 give host, and the value of speech silence data is usually -1, is not 0.

From fig. 6 it can be seen that then 0 number is 0, at this time when the sco data packet of non-2 mark is in uart_pkt1 The data packet of corresponding air transmission does not have packet drop appearance；When the sco data packet of non-2 mark is in uart_pkt2, this When uart_pkt1 Status Flag be 2, the Status Flag that can release air_pkt1 is also 2, i.e., aerial first voice data There is packet loss in packet, and the voice data that corresponding uart_pkt2 has 12 bytes is 0, as long as this is because there is packet loss in the air, correspondence Controller can give all data clear 0 to host；With should it is non-2 mark sco data packets be in uart_pkt3 when, Uart_pkt1=uart_pkt2=2 at this time, can release air_pkt1=air_pkt2=0, and corresponding uart_pkt3 has 24 The voice data of byte is 0；With should the sco data packets of non-2 mark be in uart_pkt4 when, uart_pkt1=at this time Uart_pkt2=uart_pkt3=2 can release air_pkt1=air_pkt2=air_pkt3=0, corresponding uart_ The voice data that pkt4 has 36 bytes is 0；But the sco data packet of this non-2 mark can not be in uart_pkt5, if When the sco data packet of non-2 mark is in uart_pkt5, uart_pkt5！=2, uart_pkt1=uart_pkt2=at this time Uart_pkt3=uart_pkt4=2, because the data of uart_pkt5 are contained in air_pkt4 just, if uart_pkt5 Mark be not 2, then the mark of air_pkt4 is also not 2, then the mark of uart_pkt4 is also certainly non-2, this and discovery the One is not that the premise that 2 mark sco data packets are uart_pkt5 is disagreed.

By above-mentioned analysis it is found that by the Status Flag in the end host detection sco packet, the first of voice data just can determine that Beginning aligned position, such as when the Status Flag for detecting a certain VoP is not 2, calculate the sco packet of this non-2 mark From the number for the data 0 for beginning setting up sco link, if the number of data 0 is 0, determine to receive voice since uart_pkt1 Data, since uart_pkt1 as unit of the period according to host termination receive VoP carry status indicator and The status indicator and voice data that voice data carries come the anti-VoP for pushing away aerial actual transmissions；If the number of data 0 It is 12, then determines to receive voice data since uart_pkt2, after counting p-2 VoP again since uart_pkt2 As unit of the period according to host termination receive the status indicator that carries of VoP and voice data come counter push away aerial reality The status indicator and voice data that the VoP of border transmission carries；Similarly, if the number of data 0 be 24, determine from Uart_pkt3 starts to receive voice data, is counted again after p-3 VoP since uart_pkt3 as unit of the period According to host termination receive VoP carry status indicator and voice data come the anti-voice for pushing away aerial actual transmissions The status indicator and voice data that data packet carries, similarly, if the number of data 0 is 36, judgement connects since uart_pkt4 Voice data is received, is received as unit of the period according to host termination after counting p-4 VoP again since uart_pkt4 Obtain the state that status indicator and the voice data that VoP carries carry come the anti-VoP for pushing away aerial actual transmissions Mark and voice data, this 4 VoP for being not limited to 60 byte of air transmission correspond to host termination and receive 5 48 bytes A kind of this situation of the data packet of voice.

Specifically, recycling the data received according to the end host and mark as unit of the period instead releases aerial practical biography The status indicator and voice data that defeated VoP carries.As shown in fig. 6, the uart_pkt1 and uart_pkt5 at the end host Just completely comprising in skyborne air_pkt1 and air_pkt4.So the mark of air_pkt1 and air_pkt4 is respectively etc. In the mark of uart_pkt1 and uart_pkt5.Aerial data packet either correct either error or packet loss, so can only There are 0,1,2 marks, without the mark (i.e. mark 3) of part packet loss.

If the mark of air_pkt1 and air_pkt4 is not 1, then we can be by air_pkt1 and uart_pkt2 The mark of air_pkt2 is obtained, obtains the mark of air_pkt3 by air_pkt4 and uart_pkt4.If air_pkt1=0, As uart_pkt2=0, air_pkt2=0；Work as air_pkt1=0, when uart_pkt2=1, air_pkt2=1；Work as air_ When pkt1=0, uart_pkt2=3, air_pkt2=2；When paying attention to air_pkt1=0 at this time, the mark of uart_pkt2 can not 2 can be equal to, because it already contains part valid data.If air_pkt1=2, as uart_pkt2=1, air_ Pkt2=1；Work as air_pkt1=2, when uart_pkt2=2, air_pkt2=2；Work as air_pkt1=2, uart_pkt2=3 When, air_pkt2=0；When paying attention to air_pkt1=2 at this time, the mark of uart_pkt2 can not be equal to 0, because it has had Partial data is lost, and the above conversion can be abstracted as following mapping table, refering to shown in table 4.It should be noted that known aerial biography The state of a defeated VoP be (the corresponding end host of next VoP of non-1) and corresponding air transmission The state of VoP can derive the state of next VoP of air transmission by following mapping table.

Embodiment two corresponds to host termination with the VoP of 70 byte of air transmission (air) and receives 30 byte voices Data packet carries out the analyzing examples above method.

Embodiment two

It first has to ask it according to the sco packet size that the sco packet size and control terminal (controller) of air transmission export Least common multiple, as shown in figure 8,30 and 70 least common multiple is 210, i.e., uart interface in the end host often receives 7 and (counts 210 are calculated divided by 30 size) a sco packet when correspond to air transmission 3 (i.e. calculating 210 divided by 70 size) a sco packet.

Indicate that host terminates first to the 7th sco number in some period received with uart_pkt1~uart_pkt7 According to packet, air_pkt1~air_pkt3 is indicated the first of corresponding air transmission to third sco data packet.

Further, confirm the starting aligned position of voice data.Controller is in sco link establishment under normal circumstances After start to send number to host, just started be initialization voice data that a segment mark is 2, usually a few tens of milliseconds to several hundred millis Second, followed by normal data.In the mark of the end host detection sco packet, when finding it is not 2, this non-2 mark is calculated The number for 0 data that sco packet most starts, as long as it should be noted that there is packet loss in the air, corresponding controller can be by institute There are data clear 0 to give host, and the value of speech silence data is usually -1, is not 0.

As can be seen from Figure 8, when the sco data packet of non-2 mark is in uart_pkt1, then 0 number is 0, at this time The data packet of corresponding air transmission does not have packet drop appearance；When the sco data packet of non-2 mark is in uart_pkt3, this When uart_pkt1=uart_pkt2=2, i.e. aerial first VoP of air_pkt1=2 can be released and packet loss occur, The voice data that corresponding uart_pkt3 has 10 bytes is 0, as long as this is because there is packet loss in the air, it is corresponding Controller can give all data clear 0 to host；With should it is non-2 mark sco data packets be in uart_pkt5 when, this When uart_pkt1=uart_pkt2=uart_pkt3=uart_pkt4=2, air_pkt1=air_pkt2=can be released The voice data that 0, corresponding uart_pkt5 have 20 bytes is 0；When the sco data packet of non-2 mark is in uart_pkt2, this When uart_pkt1 Status Flag be 2, the Status Flag that can release air_pkt1 is also 2, further uart_pkt2's Status Flag is also 2, this is contradicted with the sco data packet of non-2 mark in uart_pkt2, therefore the sco data of non-2 mark Packet can not be in uart_pkt2, and similarly, the sco data packet of non-2 mark can not be in uart_pkt4 and uart_pkt6； But the sco data packet of this non-2 mark can not be in uart_pkt7, if not the sco data packet of 2 marks is in uart_ When pkt7, uart_pkt7！=2, uart_pkt1=uart_pkt2=uart_pkt3=uart_pkt4=uart_ at this time Pkt5=uart_pkt6=2, because the data of uart_pkt7 are contained in air_pkt3 just, if the mark of uart_pkt7 Will is not 2, then the mark of air_pkt3 is also not 2, then the mark of uart_pkt6 is also certainly non-2, this and discovery first It is not that the premise that 2 mark sco data packets are uart_pkt7 is disagreed.

By above-mentioned analysis it is found that by the Status Flag in the end host detection sco packet, the first of voice data just can determine that Beginning aligned position, such as when the Status Flag for detecting a certain VoP is not 2, calculate the sco packet of this non-2 mark From the number for the data 0 for beginning setting up sco link, if the number of data 0 is 0, determine to receive voice since uart_pkt1 Data, since uart_pkt1 as unit of the period according to host termination receive VoP carry status indicator and The status indicator and voice data that voice data carries come the anti-VoP for pushing away aerial actual transmissions；If the number of data 0 It is 10, then determines to receive voice data since uart_pkt3, after counting p-3 VoP again since uart_pkt3 As unit of the period according to host termination receive the status indicator that carries of VoP and voice data come counter push away aerial reality The status indicator and voice data that the VoP of border transmission carries；Similarly, if the number of data 0 be 20, determine from Uart_pkt5 starts to receive voice data, is counted again after p-5 VoP since uart_pkt5 as unit of the period According to host termination receive VoP carry status indicator and voice data come the anti-voice for pushing away aerial actual transmissions The status indicator and voice data that data packet carries, this 3 VoP for being not limited to 70 byte of air transmission correspond to host Termination receives a kind of this situation of the data packet of 7 30 byte voices.

Specifically, recycling the data received according to the end host and mark as unit of the period instead releases aerial practical biography The status indicator and voice data that defeated VoP carries.Aerial data packet is either correct either to malfunction or loses Packet, so can only have 0,1,2 marks, without the mark (i.e. mark 3) of part packet loss.

Specifically, with m=30bytes, n=70bytes, p=7, for q=3, as shown in fig.8, counter push through journey such as Under: air_pkt (i)=uart_pkt ((p/q) * i), wherein i is the positive integer greater than 0 and less than or equal to p, and p is uart_ Packet number in pkt a cycle, m are the size of uart_pkt, and q is the packet number in air_pkt a cycle, n air_ The size of pkt, p/q are that p is rounded divided by q.

I.e. the Status Flag of air_pkt1 is identical as the Status Flag of uart_pkt2, i.e. air_pkt1=uart_pkt2； The Status Flag of air_pkt2 and the Status Flag of uart_pkt4 are identical, i.e. air_pkt2=uart_pkt4；Air_pkt3's Status Flag is identical as the Status Flag of uart_pkt6, i.e. air_pkt3=uart_pkt6.
