In the field of smart home, wireless gateways have become relay devices for most wireless smart devices in the home to access the Internet.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0053] To facilitate understanding of the embodiments of the present invention, specific embodiments will be further explained below with reference to the accompanying drawings. The embodiments do not limit the embodiments of the present invention.

[0054] Figure 1 A schematic diagram of a flow chart of a channel resource allocation method provided by an embodiment of the present invention is shown as follows: Figure 1 As shown, the method specifically includes:

[0055] S11. Obtain historical communication information between the gateway and the device.

[0056] The channel resource allocation method provided in an embodiment of the present invention is applied to a gateway, which may be a Wi-Fi 6 gateway. The gateway can connect and communicate with multiple devices, such as air conditioners, humidity control devices, and lighting devices. Specifically, the channel resource allocation method determines a target channel based on the communication properties of the device, allowing the device to communicate with the gateway through the target channel. This enables staggered communication between multiple devices and the gateway, avoiding frequency band congestion.

[0057] In this embodiment, during the historical communication process between the device and the gateway, the gateway will obtain and record information such as the device identification, communication start time, communication duration, and communication channel used as historical communication information.

[0058] S12: Determine the communication attribute of the device according to the historical communication information.

[0059] In this embodiment, the communication attribute may represent the frequency, duration, and regularity of device communication. The communication attribute of the device is determined based on the communication duration and time in historical communication information.

[0060] Specifically, the device's daily communication frequency can be determined based on the communication time, and whether the communication is regular can be determined based on the communication frequency, communication duration, and communication time. Multiple thresholds for categorizing communication duration and communication frequency can be pre-set. Based on the thresholds for the device's communication frequency and communication duration, the device's communication attributes are categorized into the following types: Category A attributes: frequent and regular communication frequency, with long communication duration; Category B attributes: low and regular communication frequency, with long communication duration; Category C attributes: frequent and regular communication frequency, with short communication duration; Category D attributes: low and regular communication frequency, with short communication duration; and Category E attributes: uncertain communication frequency and duration.

[0061] S13. Determine a target channel corresponding to the device according to the communication attribute, so that the device communicates with the gateway using the target channel.

[0062] In this embodiment, since the communication duration, communication frequency and communication time of devices with different communication attributes are different, it is necessary to set a corresponding target channel for each device with each communication attribute so that devices with the same communication attributes use the same target channel to communicate with the gateway. The method for determining the target channel may include but is not limited to using the channel that is most frequently used by devices with the same communication attributes in historical communications as the target channel of the device.

[0063] In one possible implementation, after determining the target channel of the device, the gateway may send a communication instruction or a channel identifier of the target channel to the device via the target channel, so that the device communicates with the gateway via the target channel after receiving the communication instruction or channel identifier.

[0064] The channel resource allocation method provided in this embodiment uses a gateway to obtain historical communication information between the gateway and a device; determines the device's communication attributes based on this historical communication information; and then determines a target channel corresponding to the device based on the communication attributes, allowing the device to communicate with the gateway using the target channel. This allows for the rational allocation of communication channels based on the communication attributes of the device, preventing too many devices from communicating with the gateway through the same channel, thereby reducing communication frequency band and channel congestion and effectively lowering device operating energy consumption.

[0065] Figure 2 A flow chart of another channel resource allocation method provided by an embodiment of the present invention is shown as follows: Figure 2 As shown, the method specifically includes:

[0066] S21. Obtain historical communication moments and historical communication durations between the device and the gateway; determine historical communication frequencies between the device and the gateway based on the historical communication moments; and use the historical communication moments, the historical communication duration, and the historical communication frequency as the historical communication information.

[0067] In this embodiment, it is applied to the WIFI6 gateway, and the target wake-up time and communication channels of multiple devices are arranged and allocated through the TWT scheduling plan of the WIFI6 gateway, so as to realize staggered communication between multiple devices and the gateway.

[0068] Specifically, the daily communication time between the device and the gateway within a preset time period is obtained as the historical communication time, the duration of each communication is used as the historical communication duration, the daily communication frequency is determined based on the historical communication time as the historical communication frequency, and the historical communication time, historical communication duration and historical communication frequency are used as historical communication information.

[0069] S22. Determine a communication attribute of a device according to the historical communication information; determine a communication priority of the device according to the communication attribute; and determine a target channel corresponding to the device according to the communication priority.

[0070] In this embodiment, the communication frequency, communication regularity, and communication duration of a device are determined as communication attributes based on historical communication information. The communication priority corresponding to each device with each communication attribute is then determined. If the communication times of multiple devices overlap and the number of unoccupied channels is less than the number of devices, a target channel corresponding to each device can be assigned based on the communication priority. Specifically, target channels are assigned preferentially to devices with higher priorities. The specific priority determination method is described in detail in S24-S213 and is not further elaborated here.

[0071] In one possible embodiment, the method for determining the target channel includes obtaining a historical occupancy time period of the channel. For devices that communicate regularly every day, the historical communication time period is determined based on the device's historical communication time and duration. A determination is made as to whether the historical communication time period overlaps with the channel's historical occupancy time period. If no overlap is found and the channel is currently unoccupied, the channel is determined as the target channel. For devices that communicate irregularly, any unoccupied channel is randomly selected as the target channel.

[0072] S23: Determine a target wake-up time for the device according to the historical communication information.

[0073] In this embodiment, the gateway actively wakes up the corresponding device at the target wake-up time, enabling communication between the device and the gateway. Based on historical communication information, the device's daily communication pattern is determined. For devices with regular communication patterns, the historical communication time is used as the target wake-up time. For devices with irregular communication patterns, the target wake-up time is the time the gateway receives the device's communication request.

[0074] In one possible implementation, if the target wake-up time of multiple devices is the same and the number of unoccupied channels is less than the number of devices, after allocating target channels to the multiple devices according to communication priority, the target wake-up time of the devices that are not allocated to the target channels is delayed to the time when unoccupied channels appear. This ensures that channels are allocated according to communication priority, and that the target wake-up time is determined based on historical communication information and priority.

[0075] For devices that communicate irregularly every day, it indicates that the device's communication time is urgent and random. The time when the device needs to communicate is used as the target wake-up time, and an unoccupied channel is randomly assigned as the target channel. When there is no unoccupied channel, the device with low communication priority can be controlled to enter sleep mode, and the channel where the device with low communication priority is located is used as the target channel. The device with low communication priority can be woken up after the irregular communication device completes communication or when an unoccupied channel appears.

[0076] Specifically, the communication attributes of the device include: a first attribute in steps S24-S25; a second attribute in steps S26-S27; a third attribute in steps S28-S29; a fourth attribute in steps S210-S211; and a fifth attribute in steps S212-S213. Methods for determining the communication priority, target wake-up time, and target channel of the device of the above five types of communication attributes include:

[0077] S24: When the communication attribute is a first attribute, determine that the communication priority of the device is a first priority, and the first attribute is that the historical communication time or historical communication duration of the device meets a first preset condition.

[0078] In this embodiment, a first preset condition is set, which may be: the historical communication time or historical communication duration of the device does not conform to any pattern (for example, the historical communication time of the device is 10:00 a.m., 9:20 a.m., and 7:35 p.m., or the historical communication duration of the device is six minutes, five minutes, and twenty-two minutes, indicating that the historical communication time or historical communication duration of the device conforms to the first preset condition). When the historical communication time of the device does not conform to any pattern every day, it is determined that the historical communication time conforms to the first preset condition, or when the historical communication duration of the device does not conform to any pattern, it is determined that the historical communication duration conforms to the first preset condition.

[0079] Furthermore, the communication priority of the device is determined by a first preset condition. When the historical communication time or the historical communication duration meets the first preset condition, it means that the communication attribute of the device is that the communication time and duration are irregular, and it is necessary to communicate with the gateway in a timely manner. The communication attribute of the device is determined to be the first attribute and the communication priority of the device is determined to be the first priority. The device characterized by the first attribute needs to communicate first.

[0080] S25. When the communication attribute is the first attribute, determine the moment when the gateway receives the communication request as the target wake-up moment of the device; and determine any unoccupied channel as the target channel of the device according to the first priority.

[0081] In this embodiment, when the first attribute device needs to communicate, the gateway will receive a communication request for requesting communication with the first attribute device. The communication request can be a communication request sent to the gateway by the user using other devices or the first attribute device. The time when the communication request is received is determined as the target wake-up time, and any unoccupied channel at the current time is determined as the target channel.

[0082] In one possible implementation, the usage of channels adjacent to each unoccupied channel (e.g., channel occupancy, communication rate, etc.) is obtained, and whether the unoccupied channel is interfered with by the adjacent channel is determined based on the usage. Unoccupied channels that are not interfered with by the adjacent channel communication are preferentially selected as target channels.

[0083] In one possible implementation, when there are no unoccupied channels, the remaining communication time of each channel is calculated, and the channel with the least remaining communication time is selected as the target channel, or the device with the lowest communication priority is suspended from communicating, so that the first attribute device communicates through the channel of the device with the lowest communication priority.

[0084] S26. When the communication attribute is the second attribute, determine that the communication priority of the device is the second priority, and the second attribute is that the historical communication frequency of the device is greater than the first threshold, the historical communication time and the historical communication duration both meet the second preset condition, and the historical communication duration is greater than the second threshold.

[0085] In this embodiment, a second preset condition is set in advance, and the second preset condition can be: the historical communication time and historical communication duration of the device conform to a certain pattern (for example, the historical communication time of the device is ten o'clock every morning, and each historical communication duration is ten minutes, indicating that the historical communication time and historical communication duration of the device both conform to the second preset condition). When the historical communication time of the device is the same every day or conforms to a certain pattern, it is determined that the historical communication time conforms to the second preset condition. When the historical communication duration of the device each time is the same or conforms to a certain pattern, it is determined that the historical communication duration conforms to the second preset condition.

[0086] A first threshold corresponding to the historical communication frequency and a second threshold corresponding to the historical communication duration are set. If the historical communication frequency is greater than the first threshold, it indicates that the device communicates frequently. If the historical communication duration is greater than the second threshold, it indicates that the device communicates for a long time. If both the historical communication time and the historical communication duration meet the second preset condition, it indicates that the communication regularity of the device, that is, the communication attribute of the device is that the communication frequency is frequent and regular, and the communication time is long. The device is determined to be a second-attribute device and the communication priority of the second-attribute device is determined to be the second priority, which is lower than the first priority.

[0087] S27. When the communication attribute is the second attribute, determine the historical communication time of the device as the target wake-up time of the device; and determine any unoccupied channel as the target channel of the device according to the second priority.

[0088] In this embodiment, due to the communication regularity of the second attribute device, the historical communication time of the second attribute device is first used as the target wake-up time. When the target wake-up time is reached, any unoccupied channel is selected as the target channel according to the second priority.

[0089] In one possible implementation, an unoccupied channel that is not interfered with by communications in adjacent channels is preferentially selected as the target channel.

[0090] In one possible implementation, when the target wake-up time of the second attribute device is the same as that of the first attribute device, and there are multiple unoccupied channels, target channels are allocated to the two devices respectively. When there is an unoccupied channel, the channel is determined as the target channel of the first attribute device according to the first priority. When an unoccupied channel appears again, the channel is determined as the target channel of the second attribute device, and the moment when the unoccupied channel appears is determined as the target wake-up time of the second attribute device.

[0091] S28. When the communication attribute is the third attribute, determine that the communication priority of the device is the third priority, and the third attribute is that the historical communication frequency of the device is less than or equal to the first threshold, the historical communication time and the historical communication duration both meet the second preset condition, and the historical communication duration is greater than the second threshold.

[0092] In this embodiment, the historical communication frequency is less than or equal to the first threshold, indicating that the device communicates infrequently; the historical communication duration is greater than the second threshold, indicating that the device communicates for a long time; the historical communication moments and historical communication durations both meet the second preset condition, indicating that the device communicates regularly, that is, the communication attributes of the device are low and regular communication frequency and long communication time, and the device is determined to be a third-attribute device and the communication priority of the third-attribute device is determined to be the third priority, which is lower than the second priority.

[0093] S29. When the communication attribute is the third attribute, determine the historical communication time of the device as the target wake-up time of the device; and determine any unoccupied channel as the target channel of the device according to the third priority.

[0094] In this embodiment, due to the communication regularity of the third attribute device, the historical communication time of the third attribute device is first used as the target wake-up time. When the target wake-up time is reached, any unoccupied channel is selected as the target channel according to the third priority.

[0095] In one possible implementation, an unoccupied channel that is not interfered with by communications in adjacent channels is preferentially selected as the target channel.

[0096] In one possible implementation, when the target wake-up time of the third attribute device is the same as that of the first attribute device or the second attribute device, and there are multiple unoccupied channels, target channels are allocated to the above devices respectively. When there is an unoccupied channel, the channel is determined as the target channel of the first attribute device or the second attribute device based on the first priority or the second priority. When an unoccupied channel appears again, the channel is determined as the target channel of the third attribute device, and the moment when the unoccupied channel appears is determined as the target wake-up time of the third attribute device.

[0097] S210. When the communication attribute is the fourth attribute, determine that the communication priority of the device is the fourth priority, and the fourth attribute is that the historical communication frequency of the device is greater than the first threshold, the historical communication time and the historical communication duration both meet the second preset condition, and the historical communication duration is less than or equal to the second threshold.

[0098] In this embodiment, a historical communication frequency greater than a first threshold indicates that the device communicates frequently, a historical communication duration less than or equal to a second threshold indicates that the device communicates short, and both the historical communication moments and the historical communication duration meet the second preset condition to indicate a communication regularity of the device, that is, the communication attribute of the device is frequent and regular communication frequency and short communication time, and the device is determined to be a fourth attribute device and the communication priority of the fourth attribute device is determined to be the fourth priority, which is lower than the third priority.

[0099] S211. When the communication attribute is the fourth attribute, determine a historical communication time of the device as a target wake-up time of the device; and determine any unoccupied channel as a target channel of the device according to the fourth priority.

[0100] In this embodiment, due to the fourth attribute device communication rule, the historical communication time is first used as the target wake-up time. When the target wake-up time is reached, any unoccupied channel is selected as the target channel according to the fourth priority.

[0101] In one possible implementation, an unoccupied channel that is not interfered with by communications in adjacent channels is preferentially selected as the target channel.

[0102] In one possible implementation, when the target wake-up time of the fourth attribute device is the same as that of the first attribute device, the second attribute device, or the third attribute device, and there are multiple unoccupied channels, target channels are allocated to the above devices respectively. When there is an unoccupied channel, the channel is determined as the target channel of the first attribute device, the second attribute device, or the third attribute device based on the first priority, the second priority, or the third priority. When an unoccupied channel appears again, the channel is determined as the target channel of the fourth attribute device, and the moment when the unoccupied channel appears is determined as the target wake-up time of the fourth attribute device.

[0103] S212. When the communication attribute is the fifth attribute, determine that the communication priority of the device is the fifth priority, and the fifth attribute is that the historical communication frequency of the device is less than or equal to the first threshold, the historical communication time and the historical communication duration both meet the second preset condition, and the historical communication duration is less than or equal to the second threshold.

[0104] In this embodiment, the historical communication frequency is less than or equal to the first threshold, indicating that the device communicates infrequently; the historical communication duration is less than or equal to the second threshold, indicating that the device communication time is short; the historical communication time and the historical communication duration both meet the second preset condition, indicating that the device communication regularity, that is, the communication attributes of the device are low and regular communication frequency and short communication time, and the device is determined to be a fifth attribute device and the communication priority of the fifth attribute device is determined to be the fifth priority, which is lower than the fourth priority.

[0105] S213. When the communication attribute is the fifth attribute, determine any channel as the target channel of the device according to the fifth priority; when the target channel of the device is an unoccupied channel, determine the historical communication moment of the device as the target wake-up moment; or, when the target channel of the device is an occupied channel, determine any moment of the communication interval of the occupied channel as the target wake-up moment.

[0106] In this embodiment, since the communication time of the fifth attribute device is relatively short, any channel can be selected as the target channel according to the fifth priority. When the selected channel is an unoccupied channel, the historical communication time of the fifth attribute device is determined as the target wake-up time. When the target wake-up time is reached, communication can be directly carried out on the channel; when the selected channel is an occupied channel, any time in the communication time interval of the occupied channel is determined as the target wake-up time, so that the fifth attribute device can communicate with the gateway in the communication interval of any occupied channel.

[0107] S214: When the target wake-up time is reached, control the gateway to send a wake-up message to the device using the target channel, so that the device communicates with the gateway using the target channel.

[0108] In this embodiment, the device is in a dormant state during non-target wake-up time periods. For devices that communicate regularly every day, when the target wake-up time of the device is reached, the gateway generates a wake-up message (wake-up instruction) and channel identification information. The wake-up message is used to perform TWT wake-up on the device. The wake-up message and the target channel identification are sent to the device to change the device from a dormant state to a wake-up state. After the device is awakened, the target channel is determined according to the target channel identification, and the device communicates with the gateway through the target channel. For devices that communicate irregularly every day, the user controls the device or other devices to generate a communication request for the device to communicate with the gateway. When the gateway receives the communication request, it sends a wake-up message and a target channel identification to the irregularly communicating device at the current moment, so that the device determines the target channel using the target channel identification and communicates with the gateway through the target channel.

[0109] In one possible implementation, the user can directly wake up the device that communicates irregularly. The device or other devices sends a communication request of the device to the gateway through any channel at the current moment. The gateway selects a target channel according to the communication request and sends the target channel identifier to the device.

[0110] In a possible implementation, when the communication between the device and the gateway ends, the gateway sends a sleep message to the device using a target channel, so that the device enters a sleep state based on the sleep message.

[0111] The channel resource allocation method provided by the embodiment of the present invention uses the historical communication time, historical communication duration and historical communication frequency as historical communication information. The communication attributes of the device and the communication priority of the device are determined based on the historical communication information, and the target channel and target wake-up time of each communication attribute device are determined based on the communication priority; so that the device communicates with the gateway using the target channel at the target wake-up time. In this way, the communication channel and wake-up time of the device can be managed by TWT technology based on the WIFI6 gateway, and the device can be awakened to communicate with the gateway at the target wake-up time. There is no need for the device to actively communicate with the gateway, which avoids too many devices communicating at the same time during the same period, thereby reducing the congestion of communication frequency bands and channels, and effectively reducing the working energy consumption of the device.

[0112] Figure 3 A flow chart of another channel resource allocation method provided in an embodiment of the present invention is shown as follows: Figure 3 As shown, the method specifically includes:

[0113] S01: When the WIFI6 gateway communicates with a device, it will record the device's communication time and frequency. The device will be divided into the following five types of devices based on their communication time and frequency:

[0114] S02:

[0115] 1. Class A attribute equipment: The communication frequency is frequent and regular, and the communication time is long;

[0116] 2. Class B attribute equipment: the communication frequency is low and regular, and the communication time is long;

[0117] 3. Class C attribute equipment: the communication frequency is frequent and regular, and the communication time is short;

[0118] 4. Class D attribute equipment: the communication frequency is low and regular, and the communication time is short;

[0119] 5. Class E attribute equipment: Communication frequency and communication time are irregular.

[0120] S03: The gateway performs a TWT arrangement plan for the above five devices based on the communication attributes of different devices, so that the above devices with different attributes follow the following plan when communicating data with the gateway:

[0121] S04:

[0122] 1. Class A devices: These devices are activated by TWT according to the TWT schedule, ensuring normal operation. These devices are assigned to communicate with the gateway on a channel that is free of interference. This channel is considered unoccupied and free from interference from adjacent channels.

[0123] 2. Class B devices: These devices can be awakened by TWT according to the communication rules. The gateway assigns appropriate channels for these devices to communicate. However, when the B device is communicating, other devices are only allowed to communicate with the gateway on channels that are not interfered with.

[0124] 3. Class C devices: These devices are awakened by TWT according to the communication rules in the TWT plan. However, due to the short communication time, they can be arranged to communicate on a non-interference channel after awakening.

[0125] 4. Class D devices: These devices can be awakened by TWT according to the communication rules. Since the device communication time is short, they can be arranged to communicate with the gateway on any channel after awakening.

[0126] 5. Class E devices: These devices are considered special devices that require a timely response. They must remain operational and be assigned to a non-interference channel to communicate with the gateway.
