[0001] This application relates to the field of wireless communication technology, and in particular to a device communication method, apparatus, computer equipment, and storage medium. Background Technology

[0002] With the development of wireless communication technology, various wireless communication technologies have emerged, such as BLE (Bluetooth Low Energy) communication technology. In wireless communication technology, when a communication device moves from an ideal environment to a complex environment, the signal can be interfered with, causing the wireless communication link to break.

[0003] In traditional technology, the transmission power of communication devices remains constant before and after entering the silent state, and the transmission power is switched only after entering the active state. However, if the communication device enters a complex environment during the inactive state, it will lead to instability of the wireless communication link. Summary of the Invention

[0004] Therefore, it is necessary to provide a method, apparatus, computer device, and storage medium that can improve the stability of wireless communication links to address the aforementioned technical problems.

[0005] A first aspect provides a device communication method, the method being applied to a first communication device, the method comprising:

[0006] In response to the first communication device entering a synchronous interaction state from a silent state, a synchronization frame signal is sent to the second communication device at a first transmission power; wherein the first transmission power is greater than the second transmission power, and the second transmission power is the transmission power of the first communication device in the silent state.

[0007] In a further technical solution, the transmission power corresponding to the first communication device in the active state is the third transmission power, and the first transmission power is greater than or equal to the third transmission power.

[0008] In a further technical solution, after sending a synchronization frame signal to the second communication device at the first transmission power, the method further includes:

[0009] Receive the synchronization frame response signal returned by the second communication device;

[0010] In response to the need for data interaction determined by the synchronization frame response signal, the system switches from a silent state to an active state.

[0011] In a further technical solution, the method also includes:

[0012] If no data interaction is required based on the synchronization frame response signal, return to a silent state.

[0013] In a further technical solution, before the first communication device enters the synchronous interaction state from the silent state, the method further includes:

[0014] After establishing a communication connection with the second communication device, determine whether there is an initial data interaction task between the second communication device and the second communication device;

[0015] In response to the absence of an initial data interaction task with the second communication device, the device enters a silent state; when the duration of the silent state reaches the silent maintenance time, it transitions from the silent state to a synchronous interaction state; and / or

[0016] In response to an initial data interaction task with the second communication device, it enters an active state.

[0017] In a further technical solution, the chip type information of the first communication device is obtained, and at least one of a first transmission power, a second transmission power, and a third transmission power is determined based on the chip type information, wherein the third transmission power is the transmission power corresponding to the first communication device in its active state; and / or

[0018] The system detects ambient signals around the first communication device and adjusts at least one of the first transmission power, the second transmission power, and the third transmission power according to changes in the ambient signals. The third transmission power is the transmission power corresponding to the first communication device in its active state.

[0019] In a further technical solution, the silence duration of the first communication device in a silent state is adjusted according to the change in the transmission power of the first communication device, and the silence duration is positively correlated with the transmission power of the first communication device.

[0020] In a further technical solution, the method further includes: synchronizing the silence duration with the second communication device, so that the second communication device can interact with the first communication device through the silence duration and the synchronization frame signal.

[0021] In a second aspect, a device communication apparatus is provided, the apparatus being used in a first communication device, the apparatus comprising:

[0022] The communication module is used to send a synchronization frame signal to the second communication device at a first transmission power in response to the first communication device entering a synchronous interaction state from a silent state; wherein the first transmission power is greater than the second transmission power, and the second transmission power is the transmission power of the first communication device in the silent state.

[0023] Thirdly, a computer device is provided, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the method of the first aspect.

[0024] Fourthly, a computer-readable storage medium is provided having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps of the method of the first aspect.

[0025] The aforementioned device communication method, apparatus, computer equipment, and storage medium, in response to the first communication device entering a synchronous interaction state from a silent state, transmit a synchronization frame signal to the second communication device at a first transmission power, which is greater than the second transmission power corresponding to the silent state. Therefore, the synchronization frame signal can be transmitted to the second communication device more stably. Even if the first communication device enters a complex communication environment with strong signal interference during this process, the risk of the synchronization frame signal being disconnected can be reduced, thereby reducing the risk of the entire wireless communication link being disconnected and improving the stability of the wireless communication link.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] Example 1

[0035] The device communication method provided in this application can be applied to, for example... Figure 1In the application environment shown, the first communication device 102 communicates wirelessly with the second communication device 104 via a wireless network. Wireless communication includes, but is not limited to, Bluetooth communication, BLE communication, and Wi-Fi communication.

[0036] Specifically, in response to the first communication device 102 entering a synchronous interaction state from a silent state, it sends a synchronization frame signal to the second communication device 104 at a first transmission power; wherein the first transmission power is greater than the second transmission power, and the second transmission power is the transmission power corresponding to the first communication device 102 in the silent state. The first communication device 102 can be a terminal device, including but not limited to various personal computers, laptops, smartphones, tablets, and portable wearable devices, and the second communication device 104 can be a server device, which can be implemented using a standalone server or a server cluster composed of multiple servers.

[0037] In wireless communication, the silent state of a communication device refers to the state in which the device temporarily stops sending and receiving signals to reduce power consumption, reduce interference, or enter an energy-saving mode; the active state of a communication device refers to the working state in which the device is sending or receiving data, maintaining a wireless connection, and conducting normal communication; the synchronous interaction state involved in the application refers to the temporary working state in which the device coordinates timing, aligns communication cycles, or maintains network time synchronization by exchanging specific synchronization frame signals (such as beacon frames, time synchronization messages, etc.).

[0038] like Figure 2 As shown, a device communication method is provided, which is applied to... Figure 1 Taking the first communication device as an example, the following steps may be included:

[0039] Step S202: In response to the first communication device entering the synchronous interaction state from the silent state, a synchronization frame signal is sent to the second communication device at a first transmission power; wherein, the first transmission power is greater than the second transmission power, and the second transmission power is the transmission power corresponding to the first communication device in the silent state.

[0040] In this context, the first communication device, which has established a wireless connection with the second communication device, can enter a silent state to save power when there is no need for data interaction. After entering the silent state, the first communication device will not remain asleep indefinitely, but will enter a synchronous interaction state at certain intervals according to the relevant parameters negotiated with the second communication device. In other words, it can be understood as entering a temporary working state.

[0041] In this step, in response to the first communication device entering the synchronous interaction state from the silent state, the transmission power of the first communication device can be switched from the second transmission power corresponding to the silent state to the first transmission power, and a synchronization frame signal is sent to the second communication device at the first transmission power, which is greater than the second transmission power. The time point at which the transmission power of the first communication device switches from the second transmission power to the first transmission power may include, but is not limited to, a specific time point at which the first communication device enters the synchronous interaction state from the silent state, or a specific time range before or after the specific time point at which the first communication device enters the synchronous interaction state from the silent state.

[0042] In the aforementioned device communication method, in response to the first communication device entering a synchronous interaction state from a silent state, the first communication device sends a synchronization frame signal to the second communication device with a first transmission power, which is greater than the second transmission power corresponding to the silent state. Therefore, the synchronization frame signal can be transmitted to the second communication device more stably. Even if the first communication device enters a complex communication environment with strong signal interference during this process, the risk of the synchronization frame signal being disconnected can be reduced, thereby reducing the risk of the entire wireless communication link being disconnected and thus improving the stability of the wireless communication link.

[0043] Example 2

[0044] In this embodiment, the transmission power corresponding to the first communication device in the active state is the third transmission power, and the first transmission power is greater than or equal to the third transmission power.

[0045] In this embodiment, the first transmission power can be further set to be greater than or equal to the third transmission power. The third transmission power is the transmission power of the first communication device in its active state. Generally, the second transmission power in the silent state is less than the third transmission power in the active state. By setting the first transmission power to be equal to the third transmission power, that is, by using the transmission power corresponding to the active state to interact with the second communication device for synchronization frame signals, the stability of the synchronization frame signal interaction can be ensured to a certain extent, since the transmission power in the active state is generally suitable for data interaction.

[0046] Furthermore, the first transmission power can be set to be greater than the third transmission power. That is, the synchronization frame signal can be exchanged with the second communication device at a transmission power greater than both the second and third transmission powers. By setting the first transmission power to the largest of the three states, the stability of the synchronization frame signal exchange can be further improved. Moreover, since the duration of the synchronization interaction state is relatively short, even if the first transmission power greater than the third transmission power is used to exchange with the second communication device for a short time in the synchronization interaction state, it will not cause a significant increase in power consumption. Therefore, it is possible to further improve communication stability while taking into account the need for low power consumption.

[0047] Example 3

[0048] In this embodiment, reference can be made to Figure 3 As shown, Figure 3 A flowchart illustrating a device communication method in some other embodiments is shown.

[0049] After the first communication device sends a synchronization frame signal to the second communication device at a first transmission power, the method may further include:

[0050] Step S204: Receive the synchronization frame response signal returned by the second communication device.

[0051] Step S206: In response to the determination based on the synchronization frame response signal that data interaction is required, switch from the silent state to the active state.

[0052] In this system, the first communication device can proactively send a synchronization frame signal to the second communication device at a first transmission power. This synchronization frame signal requests synchronization information such as time, frequency, or data structure from the second communication device to coordinate the communication rhythm between the two devices. Upon receiving the synchronization frame signal, the second communication device returns a synchronization frame response signal to the first communication device. This response signal provides the second communication device with its own time, frequency, or data structure information to complete information synchronization and calibration between the two devices.

[0053] Specifically, after receiving the synchronization frame response signal, the first communication device can parse and process the signal to determine whether data interaction with the second communication device is needed at the current time or within a given time period. If it is determined that data interaction with the second communication device is needed at the current time or within a given time period, the first communication device can switch from a silent state to an active state. After switching from a silent state to an active state, the first communication device interacts with the second communication device using the third transmission power corresponding to the active state. For example, the third transmission power is the conventional transmission power corresponding to the active state. Different types of devices may have different conventional transmission powers corresponding to the active state, which can be adjusted and customized according to requirements; no restrictions are imposed here.

[0054] In this embodiment, the synchronization frame response signal returned by the second communication device can accurately determine whether data interaction with the peer is required, and promptly enter the active state when data interaction is required to ensure smooth data interaction.

[0055] In a further embodiment, the method may further include:

[0056] Step S208: In response to the determination based on the synchronization frame response signal that no data interaction is required, return to the silent state.

[0057] If, based on the synchronization frame response signal, it is determined that no data interaction with the second communication device is required at the current time or within a given time period, the first communication device can return to a silent state. Upon returning to the silent state, or during the return process, the first communication device's transmission power can be switched from a first transmission power to a second transmission power. For example, the second transmission power is the normal transmission power corresponding to the silent state. Different types of devices may have different normal transmission powers corresponding to the silent state, which can be adjusted and customized as needed; no restrictions are imposed here. In this embodiment, the device directly returns to the silent state when no data interaction is required, thereby further reducing device power consumption without affecting data interaction.

[0058] Example 4

[0059] In this embodiment, before the first communication device enters the synchronous interaction state from the silent state, the method may further include:

[0060] After establishing a communication connection with the second communication device, determine whether there is an initial data interaction task between the second communication device and the second communication device;

[0061] In response to the absence of an initial data interaction task with the second communication device, the device enters a silent state; when the duration of the silent state reaches the silent maintenance time, it enters a synchronous interaction state from the silent state; and / or, in response to the presence of an initial data interaction task with the second communication device, it enters an active state.

[0062] For example, you can refer to Figure 4 As shown, Figure 4 The diagram illustrates the initial stage of wireless communication between a first communication device and a second communication device in some embodiments.

[0063] The first communication device can establish a wireless communication connection with the second communication device, for example, based on a connection request triggered by a user. This wireless communication connection can include, but is not limited to, Bluetooth, Bluetooth Low Energy, and Wi-Fi. Furthermore, after establishing the wireless communication connection, the two devices can exchange connection parameters. These parameters can include, but are not limited to, latency, connection interval, timeout, transmit power (Tx Power), and channel mapping. The latency parameter represents the time interval or interaction breathing cycle between two instances of a device entering the synchronization frame interaction state; that is, it represents the duration of the latency state. The latency parameter can be a time unit or the number of interaction breathing cycles. In the initial stage after the communication connection is established, the two devices exchanging connection parameters negotiate the communication configuration, thereby ensuring stable and efficient subsequent data communication.

[0064] Furthermore, in the initial stage after the communication connection is established, the first communication device can determine whether there is an initial data interaction task based on the connection request triggered by the user. The initial data interaction task refers to the data interaction task included in the connection request triggered by the user. For example, the connection request triggered by the user may only include a connection instruction to indicate the establishment of a wireless communication connection with the second communication device, or it may further include an initial data interaction task.

[0065] In response to the absence of an initial data interaction task between the first communication device and the second communication device, the first communication device can directly enter a silent state in the initial stage after establishing a connection. When the duration of the silent state reaches the silent maintenance time, it can then enter a synchronous interaction state from the silent state.

[0066] In response to an initial data interaction task with the second communication device, the first communication device can directly enter an active state to complete the initial data interaction task with the second communication device. Furthermore, after the initial data interaction task is completed, the communication connection with the second communication device can be terminated according to preset requirements, or it can enter a silent state to wait for the arrival of the synchronous interaction state.

[0067] Example 5

[0068] In this embodiment, the method further includes: obtaining chip type information of the first communication device, and determining at least one of a first transmission power, a second transmission power, and a third transmission power based on the chip type information, wherein the third transmission power is the transmission power corresponding to the first communication device in an active state.

[0069] In practical applications, transmission power can also be classified into levels. For example, Level 1 is ultra-high transmission power, Level 2 is conventional transmission power, and Level 3 is ultra-low transmission power. The classification rules for transmission power levels can differ for different chip types, and the range of transmission power at each level can also differ for different chip types.

[0070] In this embodiment, by acquiring the chip type information of the first communication device and flexibly configuring its transmission power in different working states, refined and personalized management of the transmission power of devices with different chip types is achieved.

[0071] Example 6

[0072] In this embodiment, the method further includes: detecting the ambient signal of the first communication device, and adjusting at least one of the first transmission power, the second transmission power and the third transmission power according to the change of the ambient signal, wherein the third transmission power is the transmission power corresponding to the first communication device in the active state.

[0073] In this embodiment, when the communication environment fluctuates, the communication quality will be affected. By detecting the surrounding environmental signals of the first communication device in real time and adaptively adjusting the corresponding transmission power under different states based on the dynamic changes of the surrounding environmental signals, it can better adapt to the communication environment, avoid co-channel interference, improve communication stability, and enhance the overall robustness and adaptability of the communication device in dynamic scenarios.

[0074] Example 7

[0075] In this embodiment, the silence duration of the first communication device in a silent state is adjusted according to the change in the transmission power of the first communication device, and the silence duration is positively correlated with the actual transmission power of the first communication device. The transmission power of the first communication device may include at least one of a first transmission power, a second transmission power, and a third transmission power.

[0076] When the communication state of the first communication device switches from one state to another, the transmission power of the first communication device will switch. That is to say, the switching between different states will cause the transmission power of the first communication device to change. Alternatively, when there are fluctuations in the communication environment, the transmission power of the first communication device may also change accordingly or dynamically and adaptively due to changes in the surrounding environmental signals.

[0077] In this embodiment, the silence duration of the first communication device in a silent state can be adjusted according to the change in the transmission power of the first communication device to adapt to the change in transmission power, thereby achieving a balance between communication stability and low power consumption requirements.

[0078] More specifically, the silence duration is positively correlated with the actual transmit power of the first communication device. For example, in response to an increase in the transmit power of the first communication device, the silence duration of the first communication device in the silent state can be increased accordingly. When the transmit power of the first communication device increases, the connection stability of wireless communication is relatively improved. However, higher transmit power will increase power consumption. Therefore, by increasing the silence duration, power consumption can be reduced to a certain extent, thereby maintaining a balance between connection stability and low power consumption performance requirements.

[0079] For example, in response to a reduction in the transmit power of the first communication device, the silence duration of the first communication device in a silent state can be reduced accordingly. When the transmit power of the first communication device is reduced, the power consumption is reduced accordingly. However, the communication stability deteriorates. Therefore, by reducing the silence duration, the frequency of synchronization frame interaction can be increased, thereby further improving the balance between stability and low power consumption performance requirements.

[0080] In practical applications, when the transmission power is divided into multiple levels, for example, level 1 is ultra-high transmission power, level 2 is conventional transmission power, and level 3 is ultra-low transmission power, the silence duration can also be divided into multiple levels accordingly. For example, level 1 corresponds to a value of 1, level 2 corresponds to a value of 5, and level 3 corresponds to a value of 10. When the transmission power is detected to switch to level 1, the silence duration dynamically switches to level 3; when the transmission power is detected to switch to level 2, the silence duration dynamically switches to level 2; and when the transmission power is detected to switch to level 3, the silence duration dynamically switches back to level 1.

[0081] Example 8

[0082] In this embodiment, the method may further include: synchronizing a silence duration with a second communication device, so that the second communication device can interact with the first communication device through the silence duration and the first communication device to exchange synchronization frame signals.

[0083] In this embodiment, by synchronizing the silence duration with the second communication device, precise coordination in communication timing is achieved between the two parties. In particular, when the silence duration of the first communication device adaptively changes with its transmission power, synchronizing the silence duration with the second communication device ensures that the first and second communication devices remain synchronously silent within the agreed silence duration. When the interaction of synchronization frame signals is required, they are synchronously awakened, thereby effectively avoiding signal conflicts or missed listening due to timing misalignment.

[0084] Example 9

[0085] The following section provides a detailed explanation of the transmit power adjustment method described in this application, using an application example. Please refer to [reference needed]. Figure 5 As shown, Figure 5 The diagram illustrates the interaction flowchart between a first communication device and a second communication device in some embodiments. Specifically, it may include the following steps:

[0086] Step S51: Establish a BLE communication connection with the second communication device;

[0087] Step S52: Negotiate connection parameters with the second communication device, including latency parameters;

[0088] No initial data interaction task is required; the system enters a silent state.

[0089] Step S53: Switch the transmission power to the second transmission power;

[0090] After the time set by Latency, it enters the synchronization frame interaction state;

[0091] Step S54: Switch the transmission power to the first transmission power;

[0092] Step S55: Perform synchronization frame signal exchange;

[0093] Data interaction is required to enter an active state;

[0094] Step S56: Switch the transmission power to the third transmission power;

[0095] Step S47: Perform data interaction.

[0096] It should be understood that, although Figures 2 to 5 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figures 2 to 4 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0099] The communication module 610 is used to send a synchronization frame signal to the second communication device at a first transmission power in response to the first communication device entering a synchronous interaction state from a silent state; wherein the first transmission power is greater than the second transmission power, and the second transmission power is the transmission power of the first communication device in the silent state.

[0100] In a further embodiment, after sending a synchronization frame signal to the second communication device at a first transmission power, the communication module 610 is also used to receive a synchronization frame response signal returned by the second communication device; in response to determining that data interaction is required based on the synchronization frame response signal, it switches from a silent state to an active state.

[0101] In a further embodiment, the communication module 610 is also configured to return to a silent state in response to a determination based on the synchronization frame response signal that no data interaction is required.

[0102] In a further embodiment, before the first communication device enters the synchronous interaction state from the silent state, the communication module 610 is further configured to, after establishing a communication connection with the second communication device, determine whether there is an initial data interaction task between the second communication device and the first communication device; if there is no initial data interaction task between the second communication device and the first communication device, enter the silent state; and when the duration of the silent state reaches the silent maintenance time, enter the synchronous interaction state from the silent state; and / or, if there is an initial data interaction task between the second communication device and the second communication device, enter the active state.

[0103] In a further embodiment, the communication module 610 is also used to obtain chip type information of the first communication device, and determine at least one of a first transmission power, a second transmission power and a third transmission power based on the chip type information, wherein the third transmission power is the transmission power corresponding to the first communication device in the active state.

[0104] In a further embodiment, the communication module 610 is also used to detect the ambient signal of the first communication device and adjust at least one of the first transmission power, the second transmission power and the third transmission power according to the change of the ambient signal, wherein the third transmission power is the transmission power corresponding to the first communication device in the active state.

[0105] In a further embodiment, the communication module 610 is also used to synchronize the silence duration to the second communication device, so that the second communication device can interact with the first communication device through the silence duration and the synchronization frame signal.
