Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a low-latency communication method and device, electronic equipment, and storage medium. Background Art

[0002] When the wireless mouse system is working, it will respond to the user's operation of the mouse in real time, and send the current coordinate information and key information of the mouse to the receiving end of the connected computer or other device, so that the device can respond accordingly based on the received information. Due to the current scene that requires frequent and fast mouse operation and the device to respond quickly, the real-time performance of the mouse wireless transmission is currently higher, that is, the mouse needs to have ultra-low latency.

[0003] Currently, in order to enable the mouse to communicate quickly with the device, the classic Bluetooth connection method is mainly used to connect the mouse and the device, and the minimum time allowed by the protocol is used as the time unit. When communicating in this connection method, the mouse will send a data packet to the connected device according to the time unit, and needs to receive the feedback of the device according to the time unit accordingly, and then use the same method to send the next data packet, so that data can be sent and received in the shortest time, reducing the delay time of the mouse.

[0004] However, since the time unit of this method is fixed, and the minimum time allowed to be selected is still relatively large for scenarios with high-frequency mouse operations, and during the communication process, data packets need to be sent and received alternately, which will also affect the transmission efficiency, the communication frequency of this method can only reach a maximum of 800HZ.

[0055] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] In this application, relational terms such as first and second, etc. are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0057] The present application embodiment provides a low-latency communication method, such as Figure 1 As shown, the specific steps include:

[0058] S101: Establish a low-power Bluetooth connection link between an operating device and a receiver of a target device.

[0059] Among them, the operating device is a device that responds to the user's operation in real time and sends corresponding operation information to the target device, such as a mouse, a game controller, an operation terminal, etc. The target device is a device that receives the operation information sent by the operating device in real time and responds in real time according to the operation information, that is, a device that needs to be operated by the operating device, such as a computer, a notebook, a TV, a monitor, etc. In addition, a low-power Bluetooth connection link needs to be established between the operating device and the target device, such as a mouse and a computer, a game controller and a monitor, etc.

[0060] It should be noted that compared with classic Bluetooth connection, the time unit of the data packet of Bluetooth low energy (BLE) connection can be set according to needs, so a smaller time unit can be set, so that the delay can be very low when data is generated and received.

[0061] However, if Figure 2 As shown in the figure, according to the Bluetooth core protocol, the communication of the low-power Bluetooth connection mode is periodic, and the period can be selected between 7.5ms-4000ms. That is, in the low-power Bluetooth connection mode, a communication cycle (Interval) consists of a communication event (Event) and an idle time (idle). Within the communication event, multiple data transmission (TX) and data reception (RX) can be performed alternately, that is, a communication requires sending a data packet to the device and receiving feedback from the device accordingly. Except for the time for sending and receiving packets within the Event, the rest of the time is idle, that is, no data is sent or received, which results in the real-time performance of the overall communication of the low-power Bluetooth connection mode being worse than the overall communication of the low-latency classic Bluetooth connection mode. As shown in the figure, Figure 2 As shown, the communication method of the target device side corresponds to that of the operating device side, which performs data reception and transmission alternately within the Event, and does not perform data reception and transmission during idle time.

[0062] In the embodiment of the present application, corresponding improvements are made to fully utilize the idle time of the communication cycle of the low-power Bluetooth connection mode, and combined with its efficient communication within the Event, so that the operating device can achieve an ultra-low latency communication.

[0063] Therefore, in the embodiment of the present application, a low-power Bluetooth connection is used for communication, so it is necessary to first establish a low-power Bluetooth connection link between the operating device and the receiver of the target device.

[0064] S102. Whenever a communication event of the low-power Bluetooth connection link ends, the operating device is controlled to enter a single-transmission mode, so as to control the operating device to respond to the user's operation in real time according to the currently set transmission time interval, and send data to the receiver of the target device through the low-power Bluetooth connection link, and the receiver of the target device is controlled to enter a single-receiving mode, so as to control the receiver of the target device to receive the data sent by the operating device according to the currently set receiving time interval.

[0065] Specifically, Figure 3 As shown, after a low-power Bluetooth connection link is established between the operating device and the receiver of the target device, communication will be carried out normally in the original data transmission and reception cycle in each communication event (Event). In order to achieve efficient communication, the idle time after the communication event ends is used to continue communication in the embodiment of the present application. Therefore, whenever a communication event of the low-power Bluetooth connection link ends, that is, after an Event ends, when the idle time period of the current communication cycle is entered, the operating device is controlled to enter the single-shot mode. In the single-shot mode, the operating device will only send data (TX) according to the user's operation, but not receive data (RX), so that communication can be carried out more quickly. In addition, data is generated according to the currently set time interval, so a shorter time interval can be set according to the demand for communication, so that the real-time performance of the operating device communication can be further improved. Although it is impossible to determine whether the sent data has been received by the device due to the lack of feedback from the receiving device, a small amount of frame loss may occur, but since high-frequency data transmission can be achieved, the difference between adjacent frame data will not be too large, and the proportion of lost frames is also very small, so it will not have much impact on the response effect of the device.

[0066] Accordingly, in order to utilize the idle time of the target device's receiving end to receive the data sent by the operating device, the target device's receiver will be controlled to enter the single-receive mode every time a communication event of the low-power Bluetooth connection link ends. Since the operating device is in the single-send mode at this time, it will not receive the data fed back by the device, so there is no need for the target device to send data to the operating device. Figure 3 As shown, in the single-receive mode, the receiver of the target device only receives data (RX) but does not send data (TX). In addition, the target device receives the data sent by the operating device according to the currently set receiving time interval. In order to receive each data packet sent by the operating device in a timely manner, the sending time interval and the receiving time interval are usually set to be consistent.

[0067] Optionally, in another embodiment of the present application, a specific implementation method of controlling the operating device to enter a single-shot mode to control the operating device to respond to the user's operation in real time according to the currently set sending time interval, and send data to the receiver of the target device through a low-power Bluetooth connection link, that is, a specific implementation method of controlling the operating device to enter a single-shot mode and send data, such as Figure 4 As shown, the following steps are included:

[0068] S401, controlling the operating device to enter the single-shot mode.

[0069] S402: Set a current sending time interval according to a current working scenario of the operating device.

[0070] It should be noted that, in order to save power consumption, in the embodiment of the present application, the current mode time interval is set according to the real-time requirements of the current working scenario of the operating device to avoid the operating device being in a state of high-frequency data transmission. For example, office scenarios, game scenarios, etc.

[0071] Among them, since the higher the real-time requirement in the current working scenario of the operating device, the higher the frequency of data to be sent, the smaller the set sending time interval is. Figure 5 As shown in the figure above, when the current working scenario of the operating device has a high requirement for real-time performance, a smaller sending time interval can be set so that data can be sent at a higher frequency. For example, when the mouse is currently in a working scenario of a game that requires real-time operation and has a high requirement for real-time performance, a smaller sending time interval can be set. Figure 5 As shown in the following figure, when the real-time requirement is low in the current working scenario of the current operating device, a larger sending time interval can be set so that data can be sent at a lower frequency. For example, when the mouse is currently in a normal office working scenario and the real-time requirement is low, a larger sending time interval can be set so that data can be sent at a lower frequency.

[0072] It should also be noted that the maximum value of the sending time interval is the interval between two communication events, that is, no data is sent. Because when the operating frequency of the operating device is low, the communication event can fully meet the needs of efficient communication, so there is no need to use idle time for communication. The minimum value of the sending time interval is zero, that is, there is no interval, and data is continuously sent to meet the very high frequency operation requirements in special scenarios.

[0073] S403: When responding to the user's operation, the control operating device sends data to the receiver of the target device through the low-power Bluetooth connection link according to the current sending time interval.

[0074] Optionally, in another embodiment of the present application, a specific implementation of step S303 is as follows: Figure 6 Shown, including games

[0075] S601 , when responding to a user's operation, the control operating device encapsulates data of a preset length into a data packet at each sending time interval.

[0076] It should be noted that, in order to achieve higher transmission frequency and efficiency, in the embodiment of the present application, the length of the one-way data will be shortened as much as possible, thereby reducing the actual time of sending data once. Therefore, it is necessary to encapsulate the data according to a set smaller length.

[0077] Specifically, since the original data packet of Bluetooth needs to be retained, the PUD length in the data packet is reduced so that the data is sent with a smaller data length. For example, taking each packet carrying 10 bytes of data as an example, Figure 7 As shown in the figure, if BLE 1M phy is used for transmission, the total length of the entire data packet is only 20 bytes, and its transmission only takes 160us. If BLE 2M phy is used for transmission, the total length of the entire data packet is 21 bytes, and the transmission only takes 84us. Therefore, if the transmission is at full load, BLE 2M phy can reach a transmission frequency of 8K, and BLE 1M can reach a transmission frequency of 4K, so it can be seen that higher frequency transmission can be achieved.

[0078] S602: Send the currently encapsulated data packet to a receiver of the target device via a low-power Bluetooth connection link.

[0079] Optionally, in another embodiment of the present application, the receiver of the target device is controlled to enter the single receiving mode, so as to control the receiver of the target device to receive the data sent by the operating device according to the currently set receiving time interval. A specific implementation method, that is, controlling the receiver of the target device to enter the single receiving mode and receive data, such as Figure 8 As shown, the following steps are included:

[0080] S801, controlling the receiver of the target device to enter a single receiving mode.

[0081] S802: Set a current receiving time interval according to a currently set sending time interval.

[0082] S803: Control the receiver of the target device to receive the data sent by the operating device according to the currently set receiving time interval.

[0083] S103: When the next communication event of the low-power Bluetooth connection link is reached, the operating device is controlled to exit the single-transmit mode and the target device is controlled to exit the single-receive mode, so that the operating device and the target device communicate according to the communication protocol of the low-power Bluetooth connection link.

[0084] It should be noted that when the next communication event of the low-power Bluetooth connection link is reached, the idle time has ended and communication needs to be carried out in a normal manner. Therefore, it is necessary to control the operating device to exit the single-send mode and control the target device to exit the single-receive mode, so that the operating device and the target device can communicate in accordance with the communication protocol of the low-power Bluetooth connection link.

[0085] The embodiment of the present application provides a low-latency communication method, wherein a low-power Bluetooth connection link is established between an operating device and a receiver of a target device, and whenever a communication event of the low-power Bluetooth connection link ends, the operating device is controlled to enter a single-transmission mode, so as to control the operating device to respond to the user's operation in real time according to the currently set transmission time interval, and to send data to the receiver of the target device through the low-power Bluetooth connection link, and the receiver of the target device is controlled to enter a single-receiving mode, so as to control the receiver of the target device to receive the data sent by the operating device according to the currently set receiving time interval, so that the idle time between two communication events can be fully utilized, and the operating device is controlled to send data at high frequency and the control device is controlled to receive data at high frequency, so as to realize high-frequency communication in idle time. Then, when the next communication event of the low-power Bluetooth connection link is reached, the operating device is controlled to exit the single-transmission mode and the target device is controlled to exit the single-receiving mode, so that the operating device and the target device communicate according to the communication protocol of the low-power Bluetooth connection link, thereby realizing a method for fully utilizing the idle time of the low-power Bluetooth connection communication to realize high-frequency communication, and the time unit in the communication event of the low-power Bluetooth connection can select a smaller time according to the demand, and high-frequency communication can also be performed, thereby realizing a communication method with ultra-low latency, which can effectively meet the real-time requirements of high-frequency operation data packets.

[0089] The target device control unit 903 is used to control the receiver of the target device to enter the single receiving mode every time a communication event of the low-power Bluetooth connection link ends, so as to control the receiver of the target device to receive the data sent by the operating device according to the currently set receiving time interval.
