Detailed Description
When the bluetooth device performs multiple services, for example, performs a paging (Page) service or an Inquiry (Inquiry) service, and there are other non-paging/Inquiry services at the same time, time division multiplexing is required at this time. However, when the bluetooth master device performs bluetooth multi-service, because a time division multiplexing manner is used to process multiple services, it often happens that the bluetooth slave device cannot receive an ID packet sent by the bluetooth master device during a certain service, and when the service is Page or Inquiry service, the bluetooth master device and the bluetooth slave device cannot be queried or cannot be successfully paired. For example, when an Inquiry Scan (Inquiry Scan) period of the bluetooth slave device is in an integral multiple relationship with a period of other non-paging/Inquiry services of the bluetooth master device, it may happen that the bluetooth slave device cannot receive an ID packet sent by the bluetooth master device through a classic bluetooth Inquiry, so that the bluetooth master device and the bluetooth slave device cannot be inquired or cannot be successfully paired.
In order to solve the above problem, when the bluetooth master device performs bluetooth multi-service, a communication cycle of a preset service is equally divided into N sub-cycles, and the preset service and a non-preset service are respectively arranged in an alternating manner in each sub-cycle, and services arranged at the start of adjacent sub-cycles are different, and the sub-cycles are related to a scanning cycle of the preset service of the bluetooth slave device. Therefore, even if the bluetooth slave device does not receive the data corresponding to the preset service sent by the bluetooth master device in the scanning period of the current preset service, the data may be received in the next scanning period, so that the probability that the bluetooth slave device receives the data sent by the bluetooth master device in the preset service as a whole can be improved.
In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.
Referring to fig. 1, a flowchart of a service configuration method of a bluetooth master device in an embodiment of the present invention is shown, and details are described below through specific steps.
In the specific implementation, when the bluetooth master device performs multiple services, multiple services need to be arranged in a time division multiplexing manner. For example, when the bluetooth master device performs dual mode search, that is, when a classic bluetooth polling (Inquiry) service and a low power consumption bluetooth scanning (BLE Scan) service are performed simultaneously, the classic bluetooth Inquiry service and the BLE Scan service are time division multiplexed, and when an Inquiry Scan cycle of the bluetooth slave device is exactly an integral multiple of a BLE Scan cycle of the bluetooth master device, an ID data packet sent by the bluetooth master device Inquiry service cannot be received by the bluetooth slave device, so that a blind area occurs.
In order to avoid the occurrence of the blind area, in a specific implementation, a communication cycle of a preset service of the bluetooth master device may be equally divided into N sub-cycles, where N is a natural number greater than 1. The sub-period is related to a scanning period of the preset service of the Bluetooth slave device.
In a specific implementation, the preset service may be a Page service or an Inquiry service. For example, when performing a Page service or an Inquiry service, 32 frequency points are generally allocated to the Page service or the Inquiry service, and the 32 frequency points are divided into two sequences (Train), which can be denoted as a-Train and B-Train for convenience of description, each Train includes 16 frequency points.
Referring to fig. 2, a schematic diagram of frequency point usage of a bluetooth master device in paging service or inquiry service in the embodiment of the present invention is shown. When performing bluetooth data transmission, each Train may include a plurality of transmission time slots 21 and reception time slots 22, each transmission time slot 21 transmits two ID data packets using different frequency points, and the reception time slot 22 monitors using the frequency point of the previous transmission time slot. The Train comprises 16 frequency points which are f1, f2, … …, f15 and f16 in sequence. Each Train takes 1.25ms 8 to 10ms, and the bluetooth protocol requires at least 256 repetitions of each Train, so that a total of 10ms 256 to 2.56s is consumed per Train.
In a specific implementation, the communication cycle of the Inquiry service may be 10.24s, that is, each time the Inquiry service needs to execute the following sequence of a-Train, B-Train, a-Train, and B-Train. And starting timing when the Bluetooth master device starts to enter the Inquiry state, finishing timing after 10.24s, and reporting to inform the Bluetooth master device that the Inquiry service is finished. The communication period of the Page service can be 5.12 s. The bluetooth protocol requires that the scan period of the Page service or the Inquiry service is at least 2.56s, while the scan period of the Page service or the Inquiry service of the current conventional bluetooth slave device is generally 1.28 s.
Therefore, in an embodiment of the present invention, when the bluetooth master device performs a bluetooth multi-service, in order to enable the bluetooth slave device to receive an ID packet sent by the bluetooth master device, especially when a Page service or an Inquiry service is performed, the probability that the bluetooth master device and the bluetooth slave device are queried and successfully paired is increased, where the sub-period is 1.28 s.
In the implementation, each Train is divided into two parts, so that the communication period of the preset service can be divided into a plurality of sub-periods. For example, when the communication cycle of the Page service is 5.26s, the Page service can be divided into 4 sub-cycles. For another example, when the communication cycle of the Inquiry service is 10.24s, it may be equally divided into 8 sub-cycles. It can be understood that, according to different scanning periods of preset services of the bluetooth slave device, the number of the divided sub-periods is different, and the specific number is not limited.
And step 12, distributing the preset service and the non-preset service in an alternative mode in each sub-period.
In a specific implementation, when the preset service and the non-preset service are allocated in an alternating manner in each sub-period, the services allocated at the start of adjacent sub-periods are different. For example, if the preset service is allocated at the beginning of the first sub-period, the non-preset service is allocated at the beginning of the second sub-period. If the non-preset service is allocated at the beginning of the first sub-period, the preset service is allocated at the beginning of the second sub-period.
In a specific implementation, each sub-period may be divided into M time slices according to a preset time slice division rule, where M is a natural number greater than 1. And respectively distributing the preset service and the non-preset service into M time slices corresponding to each sub-period in an alternating mode.
In a specific implementation, the time slice allocated by the non-default service may include one non-default service or may include multiple non-default services.
In an embodiment of the present invention, the bluetooth services performed by the bluetooth master device are a default service a and a non-default service B, respectively. Referring to fig. 3, a schematic diagram of service allocation in two adjacent sub-periods in a communication period of a preset service in the embodiment of the present invention is shown. The traffic distribution conditions in the first sub-period 31 are A, B, A, B, … …, A, B. The traffic distribution conditions in the second sub-period 32 are B, A, B, A, … …, B, A. The first sub-period and the second sub-period are adjacent sub-periods.
In another embodiment of the present invention, the bluetooth services performed by the bluetooth master device are a default service a, a non-default service B, and a non-default service C, respectively. Referring to fig. 4, a schematic diagram of service allocation in two adjacent sub-periods in a communication period of another preset service in the embodiment of the present invention is shown. The traffic allocation cases in the first sub-period 41 are a, BC, … …, A, BC. The traffic allocation case in the second sub-period 42 is BC, a, … …, BC, a. The first sub-period and the second sub-period are adjacent sub-periods.
It can be understood that the sequence and type of the non-default services allocated in the time slice allocated by the non-default service may be configured according to the actual service requirement of the bluetooth master device. For example, the preset service a, the non-preset service B, and the non-preset service C may also be allocated as follows: the service allocation conditions in a certain sub-period are A, BC, … … and A, BC, and the service allocation conditions in the adjacent sub-periods are C, A, BC, A, … … and B, A.
In a specific implementation, the preset time slice division rule may be determined according to different factors.
In an embodiment of the present invention, the preset time slice division rule is set according to a bluetooth service type. For example, according to whether the currently performed service is a Page service, an Inquiry service, a call service, a song listening service, a file transfer service, or the like, a time slice division rule is determined to obtain the time length of a time slice occupied by the preset service and a time slice not occupied by the preset service.
In another embodiment of the present invention, the time slice division rule is determined according to a scanning cycle type of the preset service, for example, a standard type, an alternate type, and the like. Wherein the standard type time window is 11.25ms, and one of the 32 frequency points of the Page service or the Inquiry service is used for monitoring. The size of the alternating type window is 22.5ms, the alternating type window is divided into two small windows, the time of each small window is 11.25ms, and different frequency points are used for monitoring.
In order to further improve the data, which is received by the bluetooth slave device and sent by the bluetooth master device during the preset service, when the bluetooth master device is in the bluetooth multi-service state, in an embodiment of the present invention, the sub-period may be divided into an even number of time slices on average.
As can be seen from the above, when the bluetooth master device performs multiple bluetooth services, a communication cycle of a preset service is equally divided into N sub-cycles, and the preset service and the non-preset service are respectively arranged in an alternating manner in each sub-cycle, and services arranged at the start of adjacent sub-cycles are different, where the sub-cycles are related to a scanning cycle of the preset service of the bluetooth slave device. Therefore, when the bluetooth master device is in the bluetooth multi-service, because the services arranged at the start of the adjacent sub-periods are different, even if the bluetooth slave device cannot receive the data corresponding to the preset service sent by the bluetooth master device in the scanning period of the current preset service, the bluetooth slave device may receive the data corresponding to the preset service sent by the bluetooth master device in the next scanning period, so that the probability that the bluetooth slave device receives the data sent by the bluetooth master device in the preset service as a whole is greatly improved, and the probability that the bluetooth master device and the bluetooth slave device are inquired or successfully paired can be improved.
In a specific implementation, when the bluetooth master device is in the bluetooth multi-service, and when a scanning period of a preset service of the bluetooth slave device is in an integral multiple relationship with a communication period of a non-preset service of the bluetooth master device, the bluetooth slave device may not receive an ID packet sent by the bluetooth master device under some services, so that a blind zone occurs. When the bluetooth master device transmits data by using the service configuration method provided in the above embodiment of the present invention, the probability that the bluetooth slave device receives the ID data packet transmitted by the bluetooth master device is improved. However, if the bluetooth master device adopts a conventional service configuration manner and does not adopt the service configuration method of the bluetooth master device provided in the above embodiment of the present invention, the problem that the bluetooth slave device cannot receive data sent by the bluetooth master device is still not solved effectively.
To solve the above problem, referring to fig. 5, an embodiment of the present invention further provides a flowchart of a service configuration method of a bluetooth slave device, which is described in detail below with reference to specific steps.
And step 51, after detecting that the current scanning period of the preset service is finished, shifting the next scanning period of the preset service by a corresponding offset according to a preset offset rule.
In a specific implementation, the offset may include: offset value and offset direction. The offset value may be determined by taking a modulo p operation of a random function, p being a natural number greater than 1. The offset direction may be determined using a modulo-2 operation of a random function.
In a specific implementation, the size of the modulo p taken by the random function may be determined according to a scanning type of a preset service. When the offset direction is determined by modulo-2 operation of a random function, the sign may be set to be positive, i.e., the offset value is added, when the modulo result is an odd number, and the sign may be set to be negative, i.e., the offset value is subtracted, when the modulo result is an even number. It is understood that, when the modulo result is an odd number, the sign may be regarded as negative, i.e. the offset value is subtracted; when the modulo result is even, the sign is taken to be positive, i.e. the offset value is added.
And step 52, calculating the starting time of the next scanning period of the preset service.
In specific implementation, a current clock is acquired, and the starting time of the next scanning period of the preset service is calculated by combining the calculated offset value and offset direction corresponding to the next scanning period of the preset service and the period of the preset service.
In a specific implementation, an internal system clock is set in the bluetooth device, and when it is detected that the calculated starting time of the next scanning period is reached, the preset service may be started to receive the data sent by the master device.
According to the above, the scanning period of the preset service of the bluetooth slave device is shifted according to the preset shifting rule, so that the situation that the scanning period is overlapped with the non-preset service period of the bluetooth master device can be avoided, and the probability of successfully receiving the data sent by the bluetooth master device can be improved even if the bluetooth master device is in the bluetooth multi-service state.
In a specific implementation, the preset service may be a paging scanning service or an inquiry scanning service. By adopting the service configuration method of the Bluetooth slave device provided by the embodiment of the invention, the success rate of the inquiry and pairing between the Bluetooth slave device and the Bluetooth master device can be improved.
In a specific implementation, the calculation of the start time of the next scan period in step 52 may be performed in the following manner, referring to fig. 6, which is a flowchart of a method for calculating the start time of the next scan period according to an embodiment of the present invention.
And step 61, calculating the offset and the starting time of the next scanning period before the offset.
In a specific implementation, under the condition that no offset is made, the starting time of the next scanning period of the preset service is calculated by adopting a formula (1):
Next_scan_time＝Scan_interval+Current_clk； (1)
wherein, Next _ Scan _ time represents the starting time of the Next scanning period, Scan _ interval represents the period of the preset service, and Current _ clk represents the Current clock.
And calculating by adopting a random function modulo n to obtain an offset, wherein the offset is random ()% n. Wherein n is a positive integer, and the operation result obtained by adopting the random function modulo n operation is any integer between 0 and n. In one implementation, the Bluetooth clock period is 312.5 μ s and the maximum offset is offsetmax312.5 μ s n, minimum offsetmin0. For example, when n is 32, the offset value ranges from 0ms to 10 ms.
In a specific implementation, the offset value is determined according to a scanning period type of a preset service, that is, the value of n is determined. The scanning cycle type of the preset service may be a standard type or an alternate type. When the preset service is a Page service or an Inquiry service, the standard type time window is 11.25ms, and one of the 32 frequency points of the Page service or the Inquiry service is used for monitoring. The size of the alternating type window is 22.5ms, the alternating type window is divided into two small windows, the time of each small window is 11.25ms, and different frequency points are used for monitoring. Therefore, the offset value corresponding to the standard type adopted by the scanning period type of the preset service may be greater than the offset value corresponding to the alternate type. The value of the specific offset value may also be determined with reference to a preset service communication period of the bluetooth master device or a bluetooth service type of the bluetooth slave device. After the scanning period of the preset service of the Bluetooth slave device is shifted, the length of the whole scanning period still floats near 1.28s, so that the requirement of a Bluetooth protocol can be met, and meanwhile, the occurrence of a blind area can be avoided.
In step 62, it is determined whether or not Random ()% 2 is 0.
If yes, executing step 63; when the judgment result is negative, step 64 is executed.
In the implementation, the starting time of the next scanning period is calculated by using the formula (2):
Next_scan_time-＝offset； (2)
the Next _ scan _ time represents the start time of the Next scanning period, the offset represents the offset, and the difference between the Next _ scan _ time and the offset is newly given to the Next _ scan _ time.
In the implementation, the starting time of the next scanning period is calculated by using the formula (3):
Next_scan_time+＝offset； (3)
wherein, the Next _ scan _ time represents the start time of the Next scanning period, the offset represents the offset, and the sum of the Next _ scan _ time and the offset is newly given to the Next _ scan _ time.
