Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and more specifically, to a low-power wireless communication method, apparatus, electronic device, and storage medium. Background Technology

[0002] True Wireless Stereo (TWS) earbuds typically use the classic Bluetooth asynchronous connectionless link (ACL) for data transmission when maintaining a connection with a central device such as a mobile phone. In a TWS earbud system, the master earbud is responsible for interacting with the mobile phone, while the slave earbud is responsible for listening to information from the mobile phone. The master and slave earbuds are synchronized through a private synchronization link.

[0003] When there is no data transmission between the phone and the earphone, the ACL link switches to Sniff mode to reduce power consumption. In existing solutions, each earphone establishes its own Sniff timing sequence, and the dual-ear link task still needs to run periodically to maintain synchronization between the master and slave earphones.

[0004] In this scenario, both Sniff timing and binaural link tasks are periodic, and their periods and starting phases are different, which can easily overlap or conflict on the time axis, causing the earphone's sleep cycle to be interrupted, the system to frequently sleep and wake up, and power consumption to increase.

The start time of the second link task is after the completion time of the first link task.

[0008] In one possible implementation, controlling the main ear to enter a low-power mode includes: The master ear is controlled to switch to a low-power mode on the first link and sends synchronization parameters to the slave ear through the second link. The synchronization parameters are used to indicate the timing information of the second link task.

[0009] In one possible implementation, there is a preset time slot offset between the start time of the second link task and the completion time of the first link task.

[0010] In one possible implementation, the method further includes: In response to the fulfillment of the low-power mode exit condition, the master ear is controlled to exit the low-power mode and an exit synchronization information is sent to the slave ear through the second link.

The first link task is executed according to a first cycle, the execution cycle of the second link task is determined according to the first cycle, and the start time of the second link task is after the completion time of the first link task.

[0017] Fourthly, this disclosure also provides a low-power wireless communication device for use in a TWS earphone system, comprising: The receiving module is used to receive synchronization parameters sent by the main ear through the second link; The determining module is used to determine the timing information of the second link task based on the synchronization parameters, wherein the execution period of the second link task is determined according to the first period of the first link task, and the start time of the second link task is after the completion time of the first link task.

[0018] Fifthly, this disclosure also provides an electronic device, including: a processor, a memory, and a bus, wherein the memory stores machine-readable instructions executable by the processor, and when the electronic device is running, the processor communicates with the memory via the bus, and when the machine-readable instructions are executed by the processor, they perform a low-power wireless communication method as described in any one of the first aspect and its various embodiments, the second aspect and its various embodiments.

Detailed Implementation

[0024] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In this article, "and / or" is merely a way of describing the relationship between related objects, indicating that there can be three relationships.

[0027] The terms "first," "second," etc., are used only for ease of description to distinguish identical or similar technical features and should not be construed as indicating or implying the relative importance or number of these technical features. Therefore, a feature defined by "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, the term "multiple" means two or more.

[0028] Research has found that, with Figure 1 Taking the TWS earphone usage scenario shown as an example, in this scenario, the mobile phone and TWS earphones maintain a connection through the classic Bluetooth ACL. The master earphone is responsible for interacting with the mobile phone, while the slave earphone is responsible for listening to information from the mobile phone. The master and slave earphones of the TWS earphones rely on a private synchronization link between the earphones for synchronization.

[0029] When there is no service between the mobile phone and the headset, the ACL link for normal communication of the headset will switch to Sniff sniffing mode (Sniff is a low-power working mode of classic Bluetooth based on the ACL link, which is a fixed periodic task). At this time, both ears will establish Sniff timing. Sniff timing has the characteristics of long period and short duration. If the dual ear link task maintains a fixed synchronization period with a high frequency, it is easy to conflict with Sniff timing.

[0030] Based on the above timing sequence, there are problems such as chaotic timing interleaving, easy timing conflicts, frequent sleep and wake-up, high power consumption, and complex logic for entering and exiting low power mode when there is no business.

[0031] To at least partially address one or more of the aforementioned problems and other potential issues, this disclosure provides a low-power wireless communication method, apparatus, electronic device, and storage medium to avoid dual-link timing conflicts, reduce frequent sleep / wake cycles, and lower power consumption.

[0032] To clearly illustrate the embodiments of this disclosure, some concepts that may appear in subsequent embodiments will be introduced first.

[0033] First Link: Refers to the classic Bluetooth ACL between the TWS earbuds and central devices such as mobile phones, used for data interaction between the earbuds and central devices.

[0034] The second link refers to the private synchronization link between the master and slave earbuds of TWS earbuds, which is used for state synchronization and parameter transmission between the master and slave earbuds.

[0035] First-link task: refers to the low-power task executed on the first link, i.e., the periodic task in Sniff mode. Sniff mode is a classic Bluetooth low-power operating mode based on ACL links, characterized by a fixed period, with a relatively long period and a short duration for each task.

[0036] Second Link Task (TaskA): Refers to the synchronization task executed on the second link, used for state synchronization and timing parameter transfer between master and slave earpieces.

[0037] The low-power wireless communication method provided in this disclosure can be applied to the master or slave earpiece in a TWS earphone system. In some possible implementations, the low-power wireless communication method can be implemented by a processor calling computer-readable instructions stored in memory, or by hardware logic circuits, or by a combination of hardware and software.

[0038] See Figure 2 This illustrates a schematic diagram of the overall architecture of the TWS earphone system provided in the embodiments of this disclosure.

[0039] A TWS earphone system consists of a master ear and a slave ear. The master ear is connected to a central device (such as a mobile phone) via a first link (BTACL link), and the master ear is connected to the slave ear via a second link (private synchronization link).

[0040] In a TWS earphone system, the master ear is responsible for interacting with the central device, while the slave ear is responsible for listening to information from the central device. The master ear and the slave ear are synchronized through a second link.

[0041] When there is no data transmission between the central device and the headset, the first link will switch to Sniff low-power mode. Sniff mode is a classic Bluetooth low-power operating mode based on ACL links, characterized by fixed-cycle tasks.

[0042] The low-power wireless communication method provided in the embodiments of this disclosure will be described in detail below.

[0043] like Figure 3 As shown, the low-power wireless communication method on the master ear side provided in this embodiment includes the following steps: S101: In response to the low-power mode entry condition being met, control the main ear to enter low-power mode; S102: In low-power mode, configure the first link task and the second link task. The first link task is executed according to the first cycle. The execution cycle of the second link task is determined according to the first cycle, and the start time of the second link task is after the completion time of the first link task.

[0044] The master ear detects whether the low-power mode entry conditions are met. After confirming that the entry conditions are met, the master ear controls itself to enter low-power mode (Sniff mode).

[0045] The main ear configures the timing of the first and second link tasks in low-power mode. For example... Figure 4 As shown, the first link task is executed according to the first cycle (Sniff cycle, denoted as INTVL1), and the execution cycle of the second link task is determined according to the first cycle (for example, the cycle of the second link task is extended to be consistent with the first cycle). The start time of the second link task is after the completion time of the first link task, and the two are staggered on the timeline to avoid overlap or conflict.

[0046] Specifically, the period of the second link task is adjusted from a shorter initial period to a longer period INTVL1, which is the same as the Sniff period. The two ears use the start time of the Sniff task as a reference point, and after a preset time slot offset INTVL2, it becomes the start time of the second link task.

[0047] like Figure 4 As shown, on the timeline, the first link task (Sniff task) is executed first, and its duration is very short. After a preset time slot offset INTVL2, the second link task (TaskA) is executed immediately afterward. The remaining time INTVL3 after the completion of the Sniff task and TaskA serves as the periodic sleep period for the main ear, achieving a first-level optimization of power consumption (corresponding to the stage shown in LV1).

[0048] Here, by adjusting the execution cycle of the second link task to match that of the first link task, frequent wake-ups caused by the two types of tasks being executed at different frequencies on the timeline are avoided, thus reducing the number of periodic wake-ups from the source. By setting the start time of the second link task after the completion time of the first link task, the two types of tasks are arranged sequentially on the timeline rather than overlapping or intersecting, thereby concentrating tasks that might otherwise be scattered across different time points into a single time window, creating conditions for continuous sleep during the remaining time period.

[0049] In the process of controlling the master ear to enter the low-power mode, the master ear switches to the low-power mode on the first link and sends synchronization parameters to the slave ear through the second link. The synchronization parameters are used to indicate the timing information of the second link task.

[0050] In other words, after the master ear switches to low-power mode, it sends synchronization parameters to the slave ear via the second link. The synchronization parameters are used to indicate the timing information of the second link task, including the execution cycle and start time slot position of the second link task. Based on the received synchronization parameters, the slave ear adjusts its own second link task timing to align the slave ear's second link task with the master ear's second link task in time.

[0051] As can be seen, the master ear sends synchronization parameters to the slave ear through the second link, enabling the slave ear to adjust its own task timing according to the timing reference of the master ear, thus achieving alignment between the master and slave ears on the time axis. This mechanism avoids the problem of phase deviation accumulation caused by the master and slave ears establishing their own timing independently, and eliminates the possibility of the dual-ear link tasks being executed at different times due to timing deviation, thereby interfering with each other or staggering wake-up.

[0052] To avoid uneven power consumption between the two ears due to prolonged use, this embodiment of the present disclosure sends a role switching command to the slave ear when a preset time is reached, so that the slave ear responds to the role switching command and switches roles.

[0053] like Figure 4 As shown, in low-power mode, the master ear undertakes the first link task, while the slave ear only undertakes the second link task. The master ear's sleep period is INTVL3, and the slave ear's sleep period is INTVL4 (INTVL4 is longer than INTVL3). The master ear's power consumption is higher than that of the slave ear. To avoid power imbalance between the master and slave ear due to timing differences, as follows... Figure 5 As shown, when the preset time is reached, the master ear sends a role switching command to the slave ear. The slave ear responds to the command and performs a role switching, changing the original master ear to the slave ear and the original slave ear to the master ear, thereby balancing the power consumption of both ears.

[0054] Here, by initiating a master-slave role switch when the preset time is reached, the extra power consumption tasks originally undertaken by the master ear are transferred to the original slave ear, thereby achieving power balance between the two ears during long-term use. This avoids the battery draining too quickly on one earbud due to long-term BT link interaction tasks, thus extending the overall battery life of both ears.

[0055] In the low-power wireless communication method provided in this embodiment, in response to meeting the low-power mode exit condition, the master ear is controlled to exit the low-power mode, and exit synchronization information is sent to the slave ear through the second link. The exit synchronization information is used to instruct the slave ear to restore the original timing of the second link task.

[0056] like Figure 6 As shown, upon confirming that the exit conditions for low-power mode are met, the Sniff mode exits. The master ear autonomously performs Sniff command interaction with the phone and then exits. Additionally, the master ear sends an unsniff command to the slave ear via TaskA and synchronizes timing parameters. Then, the slave ear resumes the ACL task based on the status and clock information obtained from TaskA, switching from Sniff mode to normal mode.

[0057] like Figure 7 As shown, the ear-side low-power wireless communication method provided in this disclosure includes the following steps: S201: Receive synchronization parameters sent by the main ear through the second link; S202: Determine the timing information of the second link task based on the synchronization parameters, wherein the execution cycle of the second link task is determined according to the first cycle of the first link task, and the start time of the second link task is after the completion time of the first link task.

[0058] Specifically, the period of the second link task is adjusted from a shorter initial period to a longer period, the same as the Sniff period. The start time of the Sniff task is used as a reference point, and after a preset time slot offset of INTVL2, the start time of the second link task is taken as such. Figure 4 As shown.

[0059] In low-power mode, the slave ear only executes the second link task and does not need to execute the first link task. Therefore, the wake-up time of the slave ear is shorter, and the sleep period INTVL4 is longer than the sleep period INTVL3 of the master ear, realizing a second-level optimization of power consumption (corresponding to the stage shown in LV2).

[0060] Here, the slave ear determines its own timing based on the synchronization parameters sent by the master ear, enabling timing synchronization between the master and slave ear with the master ear as a reference without the need for independent timing alignment negotiation. This mechanism eliminates the phase deviation caused by the master and slave ear establishing their own timing independently, eliminates the need for additional timing scanning and calibration processes, reduces the overhead of the slave ear in low-power mode, and further increases the continuous sleep time window of the slave ear.

[0061] Upon receiving the exit synchronization information sent by the master ear via the second link, the slave ear restores the timing of the second link task to its original state before low-power mode (including restoring the ACL task) based on this information, thereby exiting low-power mode.

[0062] Upon receiving a role-switching command from the master ear, the slave ear responds by executing a role switch. For example... Figure 5 As shown, the original slave ear becomes the master ear, and the original master ear becomes the slave ear, thereby balancing the power consumption of both ears.

[0063] To facilitate a further understanding of the low-power wireless communication method provided in the embodiments of this disclosure, a detailed description will be given below with reference to two specific examples.

[0064] Example 1: Timing configuration for entering low-power mode See Figure 4 The following explanation uses an INTVL1 period of 240ms as an example.

[0065] After the master ear meets the entry conditions, it switches to Sniff mode first. Then, the master ear sends synchronization parameters to the slave ear through the second link. The synchronization parameters carry the timing information of the Sniff task, the preset time slot offset INTVL2 (pre-configured by the system), and the period configuration information of TaskA.

[0066] Based on the start time of the Sniff task, and after an INTVL2 offset, the two ears set TaskA to execute after the Sniff task. The period of TaskA is extended from a shorter initial period (e.g., 30ms) to 240ms, which is the same as the Sniff period. Within the 240ms period, the Sniff task and TaskA are executed sequentially on the timeline, with an INTVL2 interval in between. After both are completed, the remaining time is used for sleep.

[0067] Example 2: Master-Slave Ear Power Equalization During the Sniff process, the master ear needs to execute the first link task (Sniff task) and the second link task (Task A), while the slave ear only needs to execute the second link task (Task A). For example... Figure 4 , 5As shown, the wake-up time of the master ear is longer (INTVL3), while the wake-up time of the slave ear is shorter (INTVL4). If this state is maintained for a long time, the power consumption of the master ear will be higher than that of the slave ear.

[0068] Therefore, when the preset time (e.g., 30 seconds) is reached, the master ear sends a role switching command to the slave ear. After the slave ear responds, it executes the role switching, realizing the role swap between the two ears. Under the new role allocation, the original slave ear (now master ear) undertakes the first link task, and the original master ear (now slave ear) only undertakes the second link task, thereby balancing the power consumption of the two ears.

[0069] The low-power wireless communication method disclosed herein has the following beneficial effects: First, by determining the execution cycle of the second link task based on the first cycle of the first link task, the cycle of the binaural link task is aligned with the cycle of the BT standard link task, reducing the number of wake-ups within a single Sniff cycle and lowering power consumption.

[0070] Second, by making the start time of the second link task follow the completion time of the first link task, the binaural link task is executed immediately after the BT link task, thus avoiding timing conflicts between the two links and further reducing frequent sleep wake-ups.

[0071] Third, by prioritizing the master ear to switch to low-power mode and sending synchronization parameters to the slave ear via the second link, the slave ear can adjust its own task time slot according to the synchronization parameters, thereby achieving timing alignment and state consistency between the two ears.

[0072] Fourth, by using preset time slot offsets to compress task gaps, the continuous sleep time is increased while ensuring that the two types of tasks do not conflict, thus further optimizing power consumption.

[0073] Fifth, by having the primary ear exit the low-power mode first and sending out exit synchronization information, the secondary ear can be synchronized back to its original timing, thus achieving simultaneous exit of the low-power mode for both ears.

[0074] Sixth, by initiating master-slave role switching within a preset time period, the power consumption imbalance between the two ears caused by timing differences is avoided, thus balancing the power consumption of both ears.

[0078] Based on the same inventive concept, this disclosure also provides a low-power wireless communication device corresponding to the low-power wireless communication method. Since the principle of the device in this disclosure for solving the problem is similar to that of the low-power wireless communication method described above, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be described again.

The first link task is executed according to a first cycle, the execution cycle of the second link task is determined according to the first cycle, and the start time of the second link task is after the completion time of the first link task.

[0080] This embodiment of the disclosure aligns the execution cycle of the binaural link task with the Bluetooth (BT) standard link task cycle, and ensures that the binaural link task executes immediately following the BT link task. This avoids timing conflicts between the two links, reduces frequent sleep / wake cycles, and lowers power consumption.

[0084] In one possible implementation, it also includes: The switching module 304 is used to send a role switching command to the slave ear when a preset time is reached, so that the slave ear responds to the role switching command and switches roles.

[0089] It should be noted that the apparatus in this embodiment can implement the various processes of the aforementioned method and achieve the same effects and functions, which will not be elaborated here.

[0090] This disclosure also provides an electronic device, which can be the master ear or slave ear in a TWS earphone system. For example... Figure 10 The diagram shown is a schematic representation of an electronic device structure provided in this embodiment of the present disclosure, including: a processor 501, a memory 502, and a bus 503. The memory 502 stores machine-readable instructions executable by the processor 501 (e.g., ...). Figure 8 The execution instructions corresponding to the control module 301 and configuration module 302 in the device, for example, Figure 9 The device includes a receiving module 401 and a determining module 402 (for corresponding execution instructions, etc.). When the electronic device is running, the processor 501 and the memory 502 communicate via the bus 503. When a machine-readable instruction is executed by the processor 501, the following processing is performed: In response to the fulfillment of the low-power mode entry conditions, the main ear is controlled to enter low-power mode. In low-power mode, a first link task and a second link task are configured.
