[0061] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0062] The application scenarios described in the embodiments of the present disclosure are used to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those of ordinary skill in the art will know that with the emergence of new application scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems. Among them, in the description of the present disclosure, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0063] In the Bluetooth audio broadcast mode, the data broadcast by the Bluetooth audio broadcast device consists of multiple audio data packets, and the Bluetooth audio receiving device receives the audio data packets sent by the Bluetooth audio broadcast device. Individual audio data packets may be lost in the audio data packets sent by the Bluetooth audio broadcast device. If the audio data packets received by the Bluetooth audio receiving device are lost audio data packets, the lost audio data packets will be compensated for packet loss. If the packet loss compensation effect is good, almost no abnormal sound can be heard during playback. If the packet loss compensation effect is not good, obvious abnormal sound can be heard during playback. In the related art, the effect of testing the packet loss compensation of the Bluetooth audio receiving device is usually directly tested in an open office environment, and the test results are easily affected by interference factors such as the environment. Therefore, the test results are random and unstable.

[0064] Based on the above problems, the embodiments of the present application provide a method for testing packet loss compensation of wireless devices, as Figure 1 shown, which is a schematic flowchart of a method for testing packet loss compensation of wireless devices provided by the embodiments of the present application. The method includes the following steps:

[0065] S101. The wireless device configures the audio data packets to be sent in each audio transmission cycle according to the packet loss configuration parameters to obtain target audio data packets, where the packet loss configuration parameters include the packet loss cycle and the number of packet losses;

[0066] S102. The wireless device broadcasts the target audio data packets so that other wireless devices use the packet loss compensation algorithm to perform packet loss compensation on the target audio data packets, and then obtain the compensated audio data and play it, where the other wireless devices are wireless devices that receive the target audio data packets through broadcasting.

[0067] In the embodiments of the present application, the wireless device first configures the audio data packets to be sent in each audio transmission period according to the packet loss configuration parameters to obtain the target audio data packets. The packet loss configuration parameters include the packet loss period and the packet loss quantity. Then, the target audio data packets are broadcast so that other wireless devices use the packet loss compensation algorithm to perform packet loss compensation on the target audio data packets, obtain the compensated audio data, and play it. Here, other wireless devices are the wireless devices that receive the target audio data packets through the broadcast. In the embodiments of the present application, by configuring the audio data packets to be sent in each audio transmission period with the packet loss configuration parameters, obtaining the target audio data packets, and broadcasting the audio data packets, the packet loss situation in the real environment is simulated, so that other wireless devices use the packet loss compensation algorithm to perform packet loss compensation on the target audio data packets, obtain the compensated audio data and play it. Compared with testing in an open office environment, the randomness of the test can be reduced, the stability of the test can be improved, and thus the packet loss compensation test effect can be improved.

[0068] It should be noted that in the embodiments of the present application, the wireless device can be a Bluetooth audio broadcast device, that is, the master device in the test system, and other wireless devices can be Bluetooth audio receiving devices that receive the target audio data packets through the broadcast, that is, the slave devices in the test system.

[0069] In one embodiment, before the wireless device configures the audio data packets to be sent, the wireless device determines the packet loss positions of the packet loss quantity in each packet loss period. When the wireless device configures the audio data packets to be sent in each audio transmission period according to the packet loss configuration parameters to obtain the target audio data packets, the audio data packets at the packet loss positions in the packet loss period are discarded to obtain the target audio data packets.

[0070] For example, taking the wireless device that sends 4 audio data packets in each audio transmission period and the wireless device determines that the 2 packet loss positions in each packet loss period are the first audio data packet P1 and the third audio data packet P3 as an example. As Figure 2 shown, it is a schematic diagram of 2 packet loss positions in a packet loss period provided by the embodiments of the present application. In the embodiments of the present application, the packet loss quantity in the configuration parameters is 2, that is, the wireless device determines 2 packet loss positions in the packet loss period, which are the positions of the first audio data packet P1 and the third audio data packet P3 respectively. The first audio data packet P1 and the third audio data packet P3 in the packet loss period are discarded to obtain the target audio data packets.

[0071] In the embodiments of the present application, the packet loss quantity in the configuration parameters can be determined according to the packet loss rate. For example, if the packet loss rate is 1% and the total number of audio data packets to be sent is 1000, then the packet loss quantity is 1000 * 1% = 10, that is, the total number of packet losses in all audio transmission periods is 10.

[0072] In one embodiment, the packet loss period is one audio transmission period among multiple audio transmission periods, and the interval between adjacent packet loss periods is N audio transmission periods, where N is a natural number.

[0073] For example, if N is 0, then each audio transmission period is a packet loss period, as Figure 3a shown; for another example, if N is 1, then there is an interval of one audio transmission period between two packet loss periods, as Figure 3b shown; for another example, if N is 2, then there is an interval of two audio transmission periods between two packet loss periods, and the packet loss period is as Figure 3c shown.

[0074] In a specific embodiment, when the wireless device determines the packet loss positions of the packet loss quantity, it can be determined in the following three ways. Each way of determining the packet loss position will be described in detail below.

[0075] Method 1:

[0076] The wireless device sets the number of audio data packets with the same interval between two adjacent packet loss positions during the packet loss period.

[0077] For example, the total number of audio data packets to be sent is 1000. If the number of audio data packets to be sent in each audio transmission period is 5, then 200 audio transmission periods are required. During each packet loss period, a packet loss position is set at the position of every other audio data packet, that is, uniform packet loss.

[0078] For the convenience of understanding, a specific embodiment will be described below.

[0079] As Figure 4 shown, it is a schematic diagram of a packet loss position provided by an embodiment of the present application. Taking the number of audio data packets to be sent in each audio transmission period as 5 as an example, if the packet loss period corresponds one-to-one with the audio transmission period, that is, each audio transmission period is a packet loss period, the number of packet loss positions in each packet loss period is 3, and the audio data packets with an interval between two adjacent packet loss positions are 1.

[0080] In a specific embodiment, the wireless device can determine each audio transmission period as a packet loss period through the configuration parameter lost_interval, that is, the configuration parameter lost_interval is 0. The positions of the first audio packet P1, the third audio packet P3, and the fifth audio packet P5 in the packet loss period 1, the positions of the first audio packet P6, the third audio packet P8, and the fifth audio packet P10 in the packet loss period 2, and the positions of the first audio packet P11, the third audio packet P13, and the fifth audio packet P15 in the packet loss period 3 are determined through the configuration parameter lost_bitmap. That is, the configuration parameter lost_bitmap is 0x15. The first audio packet P1, the third audio packet P3, and the fifth audio packet P5 in the packet loss period 1, the first audio packet P6, the third audio packet P8, and the fifth audio packet P10 in the packet loss period 2, and the first audio packet P11, the third audio packet P13, and the fifth audio packet P15 in the packet loss period 3 are discarded to obtain the target audio packets.

[0081] Among them, the configuration parameter lost_bitmap uses hexadecimal bytes. If it is necessary to discard the first audio packet, the third audio packet, and the fifth audio packet in each packet loss period, and the discarded packets are represented by 1 in binary, and the retained packets are represented by 0 in binary, that is, it can be represented as 10101 in each packet loss period. With P5 as the highest bit and P1 as the lowest bit in binary, the binary byte is 10101, and the hexadecimal conversion is 0x15.

[0082] As Figure 5 shown, it is another schematic diagram of the packet loss position provided by the embodiment of the present application. Taking the number of audio packets to be sent in each audio transmission period as 5 as an example, if every other audio transmission period is a packet loss period, the number of packet loss positions in each packet loss period is 3, and the number of audio packets between adjacent two packet loss positions is 1.

[0083] In a specific embodiment, the wireless device can determine an interval of 1 audio transmission period as the packet loss period through the configuration parameter lost_interval, that is, the configuration parameter lost_interval is 1. The wireless device determines the positions of the 1st audio data packet P1, the 3rd audio data packet P3, and the 5th audio data packet P5 in the packet loss period 1, and the positions of the 1st audio data packet P11, the 3rd audio data packet P13, and the 5th audio data packet P15 in the packet loss period 2 through the configuration parameter lost_bitmap, that is, the configuration parameter lost_bitmap is 0x15. The 1st audio data packet P1, the 3rd audio data packet P3, and the 5th audio data packet P5 in the packet loss period 1, and the 1st audio data packet P11, the 3rd audio data packet P13, and the 5th audio data packet P15 in the packet loss period 2 are discarded to obtain the target audio data packets.

[0084] Method 2:

[0085] In the packet loss period, the wireless device takes the positions of a packet loss number of consecutive audio data packets as the packet loss positions.

[0086] In the embodiments of the present application, the packet loss positions are consecutive, that is, a packet loss number of audio data packets are discarded at one time.

[0087] For example, the total number of audio data packets to be sent is 1000. If there are 5 audio data packets to be sent in each audio transmission period, then 200 audio transmission periods are required. In each packet loss period, the positions of the first 3 audio data packets in the audio data packets are set as the packet loss positions, that is, the first 3 audio data packets in the audio data packets are discarded at one time.

[0088] For another example, the total number of audio data packets to be sent is 1000. If there are 5 audio data packets to be sent in each audio transmission period, then 200 audio transmission periods are required. In each packet loss period, the positions of the last 3 audio data packets in the audio data packets are set as the packet loss positions, that is, the last 3 audio data packets in the audio data packets are discarded at one time.

[0089] For another example, the total number of audio data packets to be sent is 1000. If there are 5 audio data packets to be sent in each audio transmission period, then 200 audio transmission periods are required. In each packet loss period, the position of 1 audio data packet in the middle of the audio data packets is set as the packet loss position, that is, 1 audio data packet in the middle of the audio data packets is discarded at one time.

[0090] For ease of understanding, specific embodiments are described below.

[0091] As shown Figure 6a in the figure, it is a schematic diagram of another packet loss position provided by the embodiment of the present application. Taking 5 audio data packets to be sent in each audio transmission period as an example, if each audio transmission period is a packet loss period, the number of packet loss positions in each packet loss period is 3, and the positions of the first 3 consecutive audio data packets are taken as the packet loss positions.

[0092] In a specific embodiment, the wireless device determines that each audio transmission period is a packet loss period through the configuration parameter lost_interval, that is, the configuration parameter lost_interval is 0. The wireless device determines the positions of the first audio data packet, the second audio data packet, and the third audio data packet in each packet loss period through the configuration parameter lost_bitmap, that is, the positions of the first audio data packet P1, the second audio data packet P2, and the third audio data packet P3 in packet loss period 1, the positions of the first audio data packet P6, the second audio data packet P7, and the third audio data packet P8 in packet loss period 2, and the positions of the first audio data packet P11, the second audio data packet P12, and the third audio data packet P13 in packet loss period 3. That is, the configuration parameter lost_bitmap is 0x07. The first three audio data in each packet loss period are discarded to obtain the target audio data packet.

[0093] Among them, the configuration parameter lost_bitmap uses hexadecimal bytes. If it is necessary to discard the first audio data packet, the second audio data packet, and the third audio data packet in each packet loss period, and the discarded data packets are represented by 1 in binary, and the retained data packets are represented by 0 in binary, that is, each packet loss period can be represented as 11100. Taking P5 as the highest bit and P1 as the lowest bit in binary, the binary byte is 00111, and the conversion to hexadecimal is 0x07.

[0094] As shown Figure 6b in the figure, it is a schematic diagram of another packet loss position provided by the embodiment of the present application. Taking 5 audio data packets to be sent in each audio transmission period as an example, if each audio transmission period is a packet loss period, the number of packet loss positions in each packet loss period is 3, and the positions of the last 3 consecutive audio data packets are taken as the packet loss positions.

[0095] In a specific embodiment, the wireless device determines each audio transmission period as a packet loss period through the configuration parameter lost_interval, that is, the configuration parameter lost_interval is 0. The wireless device determines the positions of the third audio data packet, the fourth audio data packet, and the fifth audio data packet in each packet loss period through the configuration parameter lost_bitmap, that is, the positions of the third audio data packet P3, the fourth audio data packet P4, and the fifth audio data packet P5 in packet loss period 1, the positions of the third audio data packet P8, the fourth audio data packet P9, and the fifth audio data packet P10 in packet loss period 2, and the positions of the third audio data packet P13, the fourth audio data packet P14, and the fifth audio data packet P15 in packet loss period 3. That is, the configuration parameter lost_bitmap is 0x1C. The last three audio data in each packet loss period are discarded to obtain the target audio data packet.

[0096] Among them, the configuration parameter lost_bitmap uses hexadecimal bytes. If it is necessary to discard the third audio data packet, the fourth audio data packet, and the fifth audio data packet in each packet loss period, and the discarded data packets are represented by 1 in binary, and the retained data packets are represented by 0 in binary, that is, each packet loss period can be represented as 00111. According to the binary, P5 is the highest bit and P1 is the lowest bit, and the binary byte is 11100, which is converted to hexadecimal as 0x1C.

[0097] As Figure 7 shown, it is a schematic diagram of another packet loss position provided by the embodiment of the present application. Taking 5 audio data packets to be transmitted in each audio transmission period as an example, if every other audio transmission period is a packet loss period, the number of packet loss positions in each packet loss period is 3, and the positions of 3 consecutive audio data packets are used as the packet loss positions.

[0098] In a specific embodiment, the wireless device determines that every other audio transmission period is a packet loss period through the configuration parameter lost_interval, that is, the configuration parameter lost_interval is 1. The wireless device determines the positions of the first audio data packet, the second audio data packet, and the third audio data packet in each packet loss period as the packet loss positions through the configuration parameter lost_bitmap, that is, the configuration parameter lost_bitmap is 0x07. That is, the positions of the first audio data packet P1, the second audio data packet P2, and the third audio data packet P3 in packet loss period 1 are the packet loss positions, and the positions of the first audio data packet P11, the second audio data packet P12, and the third audio data packet P13 in packet loss period 2 are the packet loss positions. The first three audio data packets in each packet loss period are discarded to obtain the target audio data packet.

[0099] Method 3:

[0100] The wireless device randomly selects the positions of a number of audio data packets equal to the number of lost packets from the positions of the audio data packets in the lost packet period; and takes the selected positions of the audio data packets as the lost packet positions.

[0101] For example, if the number of audio data packets to be sent in each audio transmission period is 1000, and if there are 5 audio data packets to be sent in each audio transmission period, then for 200 audio transmission periods to be sent, in each lost packet period, the positions of any 3 audio data packets are set as the lost packet positions, that is, uneven packet loss.

[0102] For ease of understanding, the following will be described with specific embodiments.

[0103] As Figure 8a shown, it is a schematic diagram of another lost packet period provided by the embodiment of the present application. Taking 5 audio data packets to be sent in each audio transmission period as an example, if each audio transmission period is a lost packet period, and the number of lost packet positions in each lost packet period is 3, the positions of the first audio data packet, the second audio data packet, and the fifth audio data packet in the lost packet period are selected as the lost packet positions.

[0104] In a specific embodiment, the wireless device determines that each audio transmission period is a lost packet period through the configuration parameter lost_interval, that is, the configuration parameter lost_interval is 0. The wireless device determines that the positions of the first audio data packet, the second audio data packet, and the fifth audio data packet in each lost packet period are the lost packet positions through the configuration parameter lost_bitmap, that is, the configuration parameter lost_bitmap is 0x13. Through the above configuration, the wireless device determines that the positions of the first audio data packet P1, the second audio data packet P2, and the fifth audio data packet P5 in the lost packet period 1 are the lost packet positions, determines that the positions of the first audio data packet P6, the second audio data packet P7, and the fifth audio data packet P10 in the lost packet period 2 are the lost packet positions, determines that the positions of the first audio data packet P11, the second audio data packet P12, and the fifth audio data packet P15 in the lost packet period 3 are the lost packet positions, and discards the first audio data packet P1, the second audio data packet P2, and the fifth audio data packet P5 in the lost packet period 1, the first audio data packet P6, the second audio data packet P7, and the fifth audio data packet P10 in the lost packet period 2, and the first audio data packet P11, the second audio data packet P12, and the fifth audio data packet P15 in the lost packet period 3 to obtain the target audio data packets.

[0105] Among them, the configuration parameter lost_bitmap uses hexadecimal bytes. If it is necessary to discard the 1st audio data packet, the 2nd audio data packet, and the 5th audio data packet in each packet loss period, and the discarded data packets are represented by 1 in binary, and the retained data packets are represented by 0 in binary, that is, each packet loss period can be represented as 11001. In binary, P5 is the highest bit and P1 is the lowest bit, and the binary byte is 10011, which is converted to hexadecimal as 0x13.

[0106] As Figure 8b shown, it is a schematic diagram of another packet loss position provided by the embodiment of the present application. Taking the number of audio data packets to be sent in each audio sending period as 5 as an example, if each audio sending period is a packet loss period and the number of packet loss positions in each packet loss period is 3, the positions of the second audio data packet, the third audio data packet, and the fifth audio data packet in the packet loss period are selected as the packet loss positions.

[0107] In a specific embodiment, the wireless device determines that each audio sending period is a packet loss period through the configuration parameter lost_interval, that is, the configuration parameter lost_interval is 0. The wireless device determines the positions of the second audio data packet, the third audio data packet, and the fifth audio data packet in each packet loss period through the configuration parameter lost_bitmap, that is, the configuration parameter lost_bitmap is 0x16. Through the above configuration, the wireless device determines that the positions of the second audio data packet P2, the third audio data packet P3, and the fifth audio data packet P5 in packet loss period 1 are the packet loss positions, determines that the positions of the second audio data packet P7, the third audio data packet P8, and the fifth audio data packet P10 in packet loss period 2 are the packet loss positions, determines that the positions of the second audio data packet P12, the third audio data packet P13, and the fifth audio data packet P15 in packet loss period 3 are the packet loss positions, and discards the second audio data packet P2, the third audio data packet P3, and the fifth audio data packet P5 in packet loss period 1, the second audio data packet P7, the third audio data packet P8, and the fifth audio data packet P10 in packet loss period 2, and the second audio data packet P12, the third audio data packet P13, and the fifth audio data packet P15 in packet loss period 3 to obtain the target audio data packet.

[0108] Among them, the configuration parameter lost_bitmap uses hexadecimal bytes. If it is necessary to discard the second, third, and fifth audio data packets in each packet loss cycle, and the discarded data packets are represented by 1 in binary, and the retained data packets are represented by 0 in binary, that is, each packet loss cycle can be represented as 01101. According to the binary, P5 is the highest bit and P1 is the lowest bit, and the binary byte is 10110, which is converted to hexadecimal as 0x16.

[0109] As Figure 9 shown, it is a schematic diagram of another packet loss position provided by the embodiment of the present application. Taking the number of audio data packets to be sent in each audio transmission cycle as 5 as an example, if every other audio transmission cycle is a packet loss cycle, and the number of packet loss positions in each packet loss cycle is 3, the positions of the first, second, and fifth audio data packets in the packet loss cycle are selected as the packet loss positions.

[0110] In a specific embodiment, the wireless device determines that every other audio transmission cycle is a packet loss cycle through the configuration parameter lost_interval, that is, the configuration parameter lost_interval is 1. The wireless device determines the positions of the first, second, and fifth audio data packets in each packet loss cycle as the packet loss positions through the configuration parameter lost_bitmap, that is, the configuration parameter lost_bitmap is 0x13. The wireless device takes the positions of the first audio data packet P1, the second audio data packet P2, and the fifth audio data packet P5 in the packet loss cycle 1 as the packet loss positions, and takes the positions of the first audio data packet P11, the second audio data packet P12, and the fifth audio data packet P15 in the packet loss cycle 2 as the packet loss positions. The wireless device discards the first audio data packet P1, the second audio data packet P2, and the fifth audio data packet P5 in the packet loss cycle 1, and the first audio data packet P11, the second audio data packet P12, and the fifth audio data packet P15 in the packet loss cycle 2 to obtain the target audio data packet.

[0111] Among them, the configuration parameter lost_bitmap uses hexadecimal bytes. If it is necessary to discard the first, second, and fifth audio data packets in each packet loss cycle, and the discarded data packets are represented by 1 in binary, and the retained data packets are represented by 0 in binary, that is, each packet loss cycle can be represented as 11001. According to the binary, P5 is the highest bit and P1 is the lowest bit, and the binary byte is 10011, which is converted to hexadecimal as 0x13.
