Description

Technical Field

[0001] This application relates to the field of classic Bluetooth technology, and in particular to a reflective Bluetooth ear-to-ear transmission method, device, and Bluetooth headset. Background Technology

[0002] In Bluetooth pair-ear applications, it's crucial to ensure that the data received by the master / slave ear is consistent and that the reception time is essentially synchronized. Because Bluetooth uses unlicensed spectrum, which contains interference sources such as Wi-Fi and microwave ovens, during actual Bluetooth transmission, when the master and slave ear simultaneously receive data from the smart terminal, one end may receive correctly while the other receives incorrectly. Therefore, it's necessary to add interaction between the master and slave ear in pair-ear transmission mode.

[0003] In classic Bluetooth, for earbuds to interact, time slots must be reserved for master-slave transmission. During these reserved time slots, the earbuds cannot receive data packets from the terminal link. Since the total time slot resources include those for master-slave interaction and those for the terminal link, reserving too many time slots for master-slave interaction reduces the proportion of time slots available for receiving data packets from the terminal link, thus affecting the reception of such data packets.

[0004] Regarding the aforementioned technologies, the inventors discovered that existing classic Bluetooth ear-to-ear interaction suffers from the problem of consuming a large amount of time slot resources and having low time slot resource utilization. Summary of the Invention

[0010] The first earphone acts as the Bluetooth master device, and the second earphone and the terminal device act as Bluetooth slave devices. The first earphone and the paired second earphone form a master-slave pair. In the first time slot, the terminal device sends an audio packet to the first earphone, and both the first earphone and the second earphone receive the audio packet.

[0011] In the second time slot, the first earphone replies with its own reception status information to the terminal device, and carries the interaction information between the first earphone and the second earphone;

[0023] In the second time slot, the first earpiece replies with its own reception status information to the terminal device, carrying preset interaction information; then, the terminal device sends an audio packet to the second earpiece, or the terminal device initiates link management signaling;

[0024] In the third time slot, if the terminal device receives the interaction information, it replies with feedback information from the first earphone. The first earphone receives the feedback information, and at the same time, the second earphone receives the feedback information sent by the terminal device, thus completing the master-slave interaction between the first earphone and the second earphone.

[0025] At least 2×K Bluetooth time slots are reserved between the second time slot and the third time slot, where K is a natural number.

[0033] The design employs an alternating cycle, determining the interaction time slots where the first and second earpieces take turns sending interactive information between them to the terminal device.

[0034] Based on floor(N / M), determine the interaction time slot between the first earphone and the terminal device or the second earphone and the terminal device, where floor() is the floor function, M is the alternation period, and N is the current frame.

[0035] When floor(N / M) is odd, in the second time slot, the first earphone sends interactive information to the terminal device;

[0036] When floor(N / M) is even, in the second time slot, the second earpiece sends interactive information to the terminal device;

[0037] In the third time slot, if the terminal device receives the interaction information, it replies with feedback information of the interaction information. Both the first earphone and the second earphone receive the feedback information, thus completing the master-slave interaction between the first earphone and the second earphone.

[0045] In a preferred embodiment, this application may be further configured to include:

[0046] An implicit status confirmation module is used for the second earpiece to send its own reception status information to the first earpiece using the remaining reserved time slot resources; in the fourth time slot, when the reception status information sent by the first earpiece to the terminal device is ACK, the second earpiece determines that the first earpiece has correctly received the feedback information sent by the terminal device in the third time slot.

[0047] In a preferred embodiment, this application can be further configured such that the interactive information sending module includes an alternating periodic unit for determining the interactive time slot in which the first earphone and the second earphone take turns sending interactive information between the first earphone and the second earphone to the terminal device.

[0048] The alternating cycle unit determines the interaction time slot between the first earpiece and the terminal device or the second earpiece and the terminal device based on floor(N / M), where floor() is a floor operation, M is the alternating cycle, and N is the current frame. When floor(N / M) is odd, the first earpiece sends interaction information to the terminal device in the second time slot; when floor(N / M) is even, the second earpiece sends interaction information to the terminal device in the second time slot.

[0049] In a preferred embodiment, this application can be further configured such that: the interactive information sending module further includes, after the first earpiece replies with its own reception status information to the terminal device, carrying the interactive information between the first earpiece and the second earpiece, or after the second earpiece replies with its own reception status information to the terminal device, carrying the interactive information between the first earpiece and the second earpiece, the terminal device sends an audio packet to the second earpiece, or the terminal device initiates link management signaling;

[0050] At least 2×K Bluetooth time slots are reserved between the second time slot and the third time slot, where K is a natural number.

[0051] In a preferred embodiment, this application may be further configured to include:

[0052] A pre-built module is used to customize master-slave synchronization interaction based on pairwise interaction information in the Bluetooth standard protocol to obtain the pair information.

[0053] Fourthly, this application provides a Bluetooth headset.

The first earphone acts as the Bluetooth master device, and the second earphone and the terminal device act as Bluetooth slave devices. The first earphone and the paired second earphone form a master-slave pair. In the first time slot, the terminal device sends audio packets to the first earphone, and both the first and second earphones receive the audio packets, completing the interaction between the terminal device and the paired earphone. In the second time slot, the first earphone replies with its own reception status information to the terminal device, and carries the communication link between the first earphone and the paired earphone. The interaction between the two earpieces utilizes the first communication link to send master-slave interaction information to the terminal device. The first earpiece does not directly send interaction information to the second earpiece, eliminating the need for additional time slot resources and improving the utilization rate of time slot resources. In the third time slot, if the terminal device receives the interaction information, it replies with feedback information. The first earpiece receives the feedback information, and simultaneously, the second earpiece receives the feedback information sent by the terminal device. At this point, the master-slave interaction between the first and second earpieces is completed. This addresses the issue of classic Bluetooth earbud interaction consuming too many time slot resources, affecting the data transmission and reception between the terminal link and the earpieces. It achieves the goal of efficiently utilizing Bluetooth time slot resources for information exchange between master and slave earpieces, with good real-time performance. Attached Figure Description

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.

[0073] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0074] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article, unless otherwise specified, generally indicates that the preceding and following related objects have an "or" relationship.

[0075] This application provides a reflective Bluetooth ear-to-ear transmission method, the main steps of which are described below.

[0076] A first communication link is established between at least one first earphone and a terminal device, a second communication link is established between the first earphone and a paired second earphone, and a third communication link is established between at least one second earphone and the terminal device, wherein the first and second communication links are bidirectional links, and the third communication link is a unidirectional link;

[0077] The first earpiece acts as the Bluetooth master device, and the second earpiece and the terminal device act as Bluetooth slave devices. The first earpiece and the paired second earpiece form a master-slave pair.

[0078] In the first time slot, the terminal device sends an audio packet to the first earpiece, and both the first earpiece and the second earpiece receive the audio packet;

[0079] In the second time slot, the first earphone replies with its own reception status information to the terminal device, and carries the interaction information between the first earphone and the second earphone;

[0080] In the third time slot, if the terminal device receives the interaction information, it replies with feedback information. The first earphone receives the feedback information, and at the same time, the second earphone receives the feedback information sent by the terminal device, thus completing the master-slave interaction between the first earphone and the second earphone.

[0081] Among them, the interactive information and the feedback information of the interactive information are predefined dual information.

[0082] The Bluetooth master earbud exchanges data packets with the terminal device, while the Bluetooth slave earbud listens to the data packets from the terminal device.

[0083] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0084] Reference Figure 1 The communication link between the first earpiece and the terminal device is the first link, which is a bidirectional link. The communication link between the first earpiece and the second earpiece is the second link, which is also a bidirectional link. The communication link between the second earpiece and the terminal device is the third link, which is a unidirectional monitoring link. The first earpiece and the second earpiece are paired to form a master-slave pair.

[0085] Terminal devices can be mobile phones, computers, cloud platforms, etc.

[0086] Reference Figure 2 The first earpiece is designated as the Bluetooth master, and the second earpiece and the terminal device are designated as slaves. Time slot resource allocation is defined. For example, in the first time slot, the terminal device sends audio packets to the first earpiece (the data packet format can be 2DH5), and both the first and second earpieces receive the audio packets. In the second time slot, the first earpiece replies with its reception status information to the terminal device, carrying interaction information between the first and second earpieces. In the third time slot, if the terminal device receives the interaction information, it replies with feedback information. The first earpiece receives this feedback information, and simultaneously, the second earpiece receives the feedback information sent by the terminal device. Utilizing the feedback or reply characteristic of the terminal device, after receiving the interaction information, the terminal device sends back master-slave interaction information. At this point, both the first and second earpieces can receive the feedback information from the terminal device, completing the master-slave interaction between the first and second earpieces. The third time slot is located after the second time slot, with no interval in between.

[0087] The interaction information and its feedback information are predefined paired information, representing a pre-set pairwise interaction. This paired information is based on paired, custom master-slave synchronization interaction information in the Bluetooth standard protocol.

[0088] In one embodiment, the definitions of preset interactive information and feedback information of interactive information are shown in Table 1.

[0089] Table 1

[0090]

[0091]

[0092] By borrowing the predefined paired "initiate" and "respond" interaction information in the Bluetooth protocol, a new purpose is redefined to transmit "control commands" between the master and slave earpieces, and almost no dynamically changing byte information is carried, so as to realize the interaction between the master and slave earpieces.

[0093] In a reflective master-slave interaction scheme, all interactions follow the Bluetooth standard protocol.

[0094] This application draws on the principle of "mirror reflection" and innovatively designs a reflective master-slave interaction method. Instead of directly sending interaction information to the second earpiece, the first earpiece uses the first link to send pre-set interaction information to the terminal device, thereby realizing master-slave information interaction and improving the utilization rate of time slot resources.

[0095] In particular, if there are more than two master earpieces and two slave earpieces, by adopting the "reflective" interaction scheme of this application, when the terminal device feeds back master-slave interaction information to the master earpiece, both the first earpiece and the second earpiece can simultaneously receive the feedback information from the terminal device. Compared with the terminal device, the first earpiece and the second earpiece receive custom "control commands" in a "broadcast" manner, which can reduce and simplify the logic of master-slave earpiece interaction and make the design simpler.

[0096] The terminal device can also act as a Bluetooth master device, while the first and second earpieces act as Bluetooth slave devices. The first and third communication links are bidirectional links, while the second communication link is a unidirectional link (monitoring link), depending on the actual situation.

[0097] For example, in one embodiment, a reflective Bluetooth ear-to-ear transmission method further includes the following steps:

[0098] The first and second earphones are considered as Bluetooth slave devices, and the terminal device is considered as a Bluetooth master device.

[0099] In the first time slot, the terminal device sends an audio packet to the first earpiece, and both the first earpiece and the second earpiece receive the audio packet;

[0100] In the second time slot, the first earpiece replies with its own reception status information to the terminal device, carrying preset interaction information; then, the terminal device sends an audio packet to the second earpiece, or the terminal device initiates link management signaling;

[0101] In the third time slot, if the terminal device receives the interaction information, it replies with feedback information from the first earphone. The first earphone receives the feedback information, and at the same time, the second earphone receives the feedback information sent by the terminal device, thus completing the master-slave interaction between the first earphone and the second earphone.

[0102] At least 2×K Bluetooth time slots are reserved between the second time slot and the third time slot, where K is a natural number.

[0103] Specifically, refer to Figure 3 When the first and second earpieces are in the role of Bluetooth slave devices and the terminal device is in the role of Bluetooth master device, in the first time slot, the terminal device sends an audio packet to the first earpiece, and both the first and second earpieces receive the audio packet.

[0104] In the second time slot, the first earpiece replies with its own reception status information to the terminal device, carrying preset interaction information; then, the terminal device sends an audio packet to the second earpiece, or the terminal device initiates link management signaling.

[0105] In the third time slot, if the terminal device receives the interaction information, it replies with feedback information from the first earphone. The first earphone receives the feedback information, and at the same time, the second earphone receives the feedback information sent by the terminal device, completing the master-slave interaction between the first and second earphones. At least 2×K Bluetooth time slots are reserved between the second and third time slots, where K is a natural number. That is, the third time slot is separated from the second time slot by a number of Bluetooth time slots, and the number of time slots depends on the behavior of the Bluetooth terminal device.

[0106] In Bluetooth communication, the arrangement of Bluetooth slots is affected by a variety of factors, especially in multi-device communication or master device scheduling behavior, including polling other slave devices, LMP signaling, and data retransmission. In this case, the third slot will not immediately follow the second slot, but will be separated by several Bluetooth slots.

[0107] For example, the terminal device polls other slave devices and communicates with them. At least two Bluetooth time slots are reserved between the second and third time slots, meaning the third time slot will be delayed by at least two Bluetooth time slots. Each Bluetooth time slot is 625 microseconds long.

[0108] For example, when a terminal device initiates Link Management (LMP) signaling, such as link encryption or pairing operations, it occupies additional time slot resources, thereby delaying normal data transmission. At least two Bluetooth time slots are reserved between the second and third time slots, meaning that the third time slot will be delayed by at least two Bluetooth time slots, depending on the complexity of the link management signaling.

[0109] In one embodiment, in the third time slot, if the terminal device receives the interaction information and replies with feedback information, and the first earpiece receives the feedback information, and the second earpiece receives the feedback information sent by the terminal device, the method further includes:

[0110] In the third time slot, the second earphone uses the remaining reserved time slot resources to send its own reception status information to the first earphone.

[0111] In one embodiment, in the third time slot, if the terminal device receives the interaction information and replies with feedback information, and the first earpiece receives the feedback information, and the second earpiece receives the feedback information sent by the terminal device, the following steps are further included:

[0112] In the fourth time slot, the first earphone sends comprehensive reception status information to the terminal device based on its own reception status information and in combination with the reception status information sent by the second earphone.

[0113] Meanwhile, in the fourth time slot, the second earphone listens to the integrated reception status information sent by the first earphone;

[0114] In the fourth time slot, when the second earpiece sends the reception status information as ACK to the first earpiece in the third time slot, the second earpiece determines that the first earpiece has correctly received the feedback information sent by the terminal device in the third time slot.

[0115] To add "implicit confirmation" for custom control commands between the first and second earpieces, specifically, refer to... Figure 4 In the third time slot, after the terminal device sends the "feedback information", the second earpiece uses the remaining reserved time slot resources in the third time slot to send its own status information of receiving the "feedback information" to the first earpiece. At this point, the first earpiece can know whether the second earpiece has correctly received the "feedback information".

[0116] Based on its own received "feedback information" status information, the first earphone, combined with the received status information of the second earphone, sends comprehensive received status information to the terminal device in the fourth time slot.

[0117] In the fourth time slot, the second earpiece listens to the overall reception status information sent by the first earpiece. By determining whether the first earpiece sent "feedback information" indicating correct reception in the fourth time slot, the second earpiece can infer whether the first earpiece correctly received the control commands.

[0118] The specific master-slave implicit confirmation interaction logic is shown in Table 2 below.

[0119] Table 2

[0120]

[0121] When the second earpiece sends an "ACK" status message to the first earpiece in the third time slot, the first earpiece receives the "ACK" status message sent by the second earpiece in the third time slot. When the first earpiece sends an "ACK" status message to the terminal device in the fourth time slot, the second earpiece infers that the first earpiece has correctly received the "control command".

[0122] When the second earpiece sends an "ACK" status message to the first earpiece in the third time slot, the first earpiece receives the "ACK" status message sent by the second earpiece in the third time slot. When the first earpiece sends a "NACK" status message to the terminal device in the fourth time slot, the second earpiece infers that the first earpiece did not correctly receive the "control command".

[0123] Through the implicit confirmation mechanism between the master and slave earpieces, the second earpiece can, to a certain extent, infer whether the first earpiece has correctly received the information sent by the terminal device in the third time slot. This eliminates the need to wait for the terminal device to confirm whether the first earpiece has correctly received the information in the third time slot, thus assisting the terminal device in confirming whether the first earpiece has correctly received the information in the third time slot. This reduces the interaction burden on the terminal device. Furthermore, when the terminal device is busy, the implicit confirmation mechanism between the master and slave earpieces can confirm in advance whether the first earpiece has correctly received the information from the terminal device in the third time slot, which is beneficial for timely adjustment and improvement of the earpieces. This further improves the time slot utilization efficiency of the Bluetooth earpieces, resulting in better real-time performance.

[0124] In one embodiment, a reflective Bluetooth ear-to-ear transmission method further includes the following steps:

[0125] The first earphone sends comprehensive reception status information to the terminal device based on its own reception status information and the reception status information sent by the second earphone. At the same time, the second earphone listens to the comprehensive reception status information sent by the first earphone.

[0126] When the integrated reception status information is ACK, the terminal device determines that the first earphone correctly received the feedback information sent by the terminal device in the third time slot.

[0127] The terminal device is used to further confirm whether the first earphone correctly receives the information sent by the terminal device in the third time slot, so as to improve the detection accuracy, thereby reducing the probability of false judgment. It is also conducive to timely adjustment and improvement of the earphone and improving the time slot utilization efficiency of the Bluetooth earphone.

[0128] This application also provides a reflective Bluetooth ear-to-ear transmission method, the main steps of which are described below.

[0129] A first communication link is established between at least one first earphone and a terminal device, a second communication link is established between the first earphone and a paired second earphone, and a third communication link is established between at least one second earphone and the terminal device, wherein the first and second communication links are bidirectional links, and the third communication link is a unidirectional link;

[0130] The first earphone and the paired second earphone form a master-slave pair. In the first time slot, the terminal device sends an audio packet to the first earphone or the second earphone, and both the first earphone and the second earphone receive the audio packet.

[0131] The design employs an alternating cycle, determining the interaction time slots where the first and second earpieces take turns sending interactive information between them to the terminal device.

[0132] Based on floor(N / M), determine the interaction time slot between the first earphone and the terminal device or the second earphone and the terminal device, where floor() is the floor function, M is the alternation period, and N is the current frame.

[0133] When floor(N / M) is odd, in the second time slot, the first earphone sends interactive information to the terminal device;

[0134] When floor(N / M) is even, in the second time slot, the second earpiece sends interactive information to the terminal device;

[0135] In the third time slot, if the terminal device receives the interaction information, it replies with feedback information of the interaction information. Both the first earphone and the second earphone receive the feedback information, thus completing the master-slave interaction between the first earphone and the second earphone.

[0136] Among them, the interactive information and the feedback information of the interactive information are predefined dual information.

[0137] For example, the alternating period is defined as M frames, and the current frame is N. When floor(N / M) is odd, the first earpiece sends the preset "interaction information" to the terminal device in the second time slot; when floor(N / M) is even, the second earpiece sends the preset "interaction information" to the terminal device in the second time slot; where floor() is a floor-down operation.

[0138] This embodiment adds a periodic alternating interaction to the reflective master-slave interaction scheme, allowing the first and second earphones to take turns sending preset "interaction information" in the second time slot, thus achieving bidirectional interaction between the master and slave earphones. This makes the implementation more flexible and applicable. Without the periodic alternating interaction scheme, only a one-way interaction from master ear to slave ear can be achieved, which has limitations.

[0139] In summary, a reflective Bluetooth pair-ear transmission method establishes a reflective Bluetooth communication link between the terminal device and the pair of earpieces. In the first time slot, the terminal device sends audio packets to the first earpiece, and both the first and second earpieces receive the audio packets, completing the interaction between the terminal device and the pair of earpieces. In the second time slot, the first earpiece replies with its reception status information to the terminal device, carrying the interaction information between the first and second earpieces. This allows it to send master-slave interaction information to the terminal device using the first communication link. The first earpiece does not directly send interaction information to the second earpiece, eliminating the need for additional time slot resources and improving the utilization rate of time slot resources. In the third time slot, if the terminal device receives the interaction information, it replies with feedback information. The first earpiece receives the feedback information, and simultaneously, the second earpiece receives the feedback information sent by the terminal device. At this point, the master-slave interaction between the first and second earpieces is completed. This method addresses the problem of traditional Bluetooth pair-ear interaction consuming too many time slot resources, which affects the data transmission and reception between the terminal link and the earpieces. It achieves the goal of efficiently utilizing Bluetooth time slot resources for information exchange between master and slave earpieces, with good real-time performance.

[0140] A reflective Bluetooth ear-to-ear transmission method enables real-time and efficient interaction of "control commands" between master and slave ears, with high utilization of time slot resources and good real-time performance.

[0141] Furthermore, when multiple Bluetooth slave devices are present, the reflective interaction method of this application, such as "couple earphones" (i.e., two pairs of earphones connected to the same mobile phone), simplifies the transmission logic and improves the robustness of transmission due to the "broadcast" transmission mechanism adopted by the Bluetooth master device.

The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0149] Furthermore, the interactive information sending module includes an alternating periodic unit for determining the interactive time slots in which the first earphone and the second earphone take turns sending interactive information between the first earphone and the second earphone to the terminal device;

When floor(N / M) is odd, the first earpiece sends interaction information to the terminal device in the second time slot; when floor(N / M) is even, the second earpiece sends interaction information to the terminal device in the second time slot.
