[0084] 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.

[0085] Currently, Wi-Fi 7 (802.11be) is rapidly gaining popularity, while the 802.11 series of standards are constantly evolving. The 802.11bf (WLAN Sensing) working group was established in August 2020, and its Draft 8.0 is expected to be released in May 2025, which is likely to become a new feature of the next generation of Wi-Fi technology.

[0086] 802.11bf, based on the characteristics of the PHY (Physical Layer) and MAC layer, measures the distance, angle, speed, and trajectory of a target. This standard supplements perception measurement in terms of frame format and MAC layer management entity (MLME), specifying new fields, execution procedures, and control management logic for perception. However, its security considerations are not comprehensive; in practical applications, it may leave room for network attacks. For example, a large number of STAs could frequently initiate perception requests to occupy physical resources for normal services; perception characteristics could also be used to understand the situation in the space where the AP is located (e.g., whether there are people there, and how many people are there). Based on this, this application proposes a perception processing method, specifically a protection method for WLAN perception functions, which can improve the security of perception processing.

[0087] It should be noted that this application can be applied to smart home and enterprise WLAN services based on WLAN sensing capabilities.

[0100] The sensing processing method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, the wireless access device 102 communicates with the terminal device 101 and the control terminal 103 via a network. Specifically, refer to... Figure 1The control terminal 103 sends perception permission configuration information to the wireless access device 102; the perception permission configuration information is used to characterize the perception permission configuration information for the terminal device 101. Based on the received perception permission configuration information, the wireless access device 102 determines the target perception capability parameters matching the perception permissions of the terminal device 101, and sends the target perception capability parameters to the terminal device 101; the target perception capability parameters are used to characterize the parameters corresponding to the perception capabilities authorized by the wireless access device 102 for use by the terminal device 101. The terminal device 101 performs perception processing based on the received target perception capability parameters. The terminal device 101 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, projection devices, etc. Portable wearable devices can be smartwatches, smart bracelets, head-mounted devices, etc. Head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc.; the terminal device 101 can refer to a STA (Stationary Awareness Center). Wireless access device 102 can refer to AP or PCP; control terminal 103 can refer to AC or network management.

[0101] In one exemplary embodiment, such as Figure 2 As shown, a perception processing method is provided, which is applied to... Figure 1 Taking a wireless access device as an example, the explanation includes the following steps S201 to S203. Wherein:

[0102] Step S201: Receive perception permission configuration information sent by the control terminal; the perception permission configuration information is used to represent the configuration information of perception permissions for the terminal device.

[0103] Among them, the perception permissions of terminal devices refer to the perception capabilities that wireless access devices authorize terminal devices to use, such as distance measurement, angle measurement, speed measurement, motion trajectory measurement, number of people in a space, human presence detection, intrusion detection, fall detection, and breathing detection. Different perception permissions correspond to different perception capabilities. For example, the perception permission corresponding to terminal device A is intrusion detection, while the perception permission corresponding to terminal device B is fall detection.

[0104] It should be noted that the sensing permissions of terminal devices can also be tiered. For example, terminal devices (STAs) can be divided into high-permission, normal-permission, and restricted-permission categories, clearly defining the scope of sensing capabilities that each level of terminal device can access. Furthermore, the sensing capabilities involved in this application may refer to WLAN-based sensing capabilities.

[0105] Among them, the perception permission configuration information refers to the configuration information for the perception permissions of terminal devices. It is used to clarify the perception permissions of terminal devices and the perception capability parameters corresponding to the perception permissions of terminal devices. For example, which terminal devices have perception permissions, what the perception permissions of the terminal devices are, and what the perception capability parameters corresponding to the perception permissions of the terminal devices are.

[0106] For example, the control terminal generates configuration information for the perception permissions of the terminal device as perception permission configuration information, and sends the perception permission configuration information to the wireless access device; the wireless access device configures the perception permissions of the terminal device based on the received perception permission configuration information to determine the perception permissions of the terminal device.

[0107] Step S202: Based on the perception permission configuration information, determine the target perception capability parameters that match the perception permissions of the terminal device; the target perception capability parameters are used to characterize the parameters corresponding to the perception capabilities that the wireless access device authorizes the terminal device to use.

[0108] The perception permission configuration information includes the perception permissions of the terminal device, and the target perception capability parameters corresponding to the perception permissions of the terminal device.

[0109] Among them, the target sensing capability parameters corresponding to the sensing permissions of terminal devices refer to the parameters corresponding to the sensing capabilities authorized by the wireless access device to the terminal device, such as sensing accuracy (e.g., distance measurement accuracy ±0.5m), detectable frequency band (e.g., 2.4GHz, 5GHz), and maximum detection distance (e.g., 10 meters, 30 meters). For example, the wireless access device authorizes terminal device A to use the intrusion detection function, and the wireless access device authorizes terminal device B to use the fall detection function.

[0110] For example, the wireless access device determines the perception permissions of the terminal device based on the received perception permission configuration information; for example, based on the device identifier (such as device number) of the terminal device, it queries the perception permission configuration information to obtain the perception permissions corresponding to the device identifier of the terminal device, which is used as the perception permissions of the terminal device; then, based on the perception permission configuration information, it determines the perception capability parameters that match the perception permissions of the terminal device, which are used as the target perception capability parameters.

[0111] Step S203: Send the target perception capability parameters to the terminal device, so that the terminal device can perform perception processing based on the target perception capability parameters.

[0112] Among them, perception processing refers to the terminal device actively initiating perception tasks (such as initiating perception measurement), or the terminal device acting as a cooperative perception device, cooperating with the wireless access device to perform perception tasks (such as being called for perception measurement).

[0113] For example, in a smart home scenario, a smart switch (STA) needs to determine whether "there is someone in the room" in order to automatically control the lights. The STA actively sends a "perception request frame" to the AP, explicitly requesting the use of the "human presence detection" function. After receiving the request, the AP schedules channel resources to send perception signals (such as OFDM waveforms) and receives reflected signals. After calculation, the AP returns the perception result that "there is someone in the room" to the STA. The STA triggers the linkage (turns on the lights) based on the result.

[0114] For example, in an indoor intrusion detection scenario, the homeowner sets up "away mode," and the AP initiates the global "indoor intrusion monitoring" task. The AP sends a "sensing call command" to the smart speaker (STA) in the living room, requesting it to cooperate in receiving reflected signals. The AP sends a sensing signal, and the smart speaker (STA) receives the signal reflected by an obstacle (such as an intruder) and feeds the signal data back to the AP. The AP combines the signals it receives with the data fed back by the STA to accurately determine "intrusion behavior" and trigger an alarm. During this process, the STA only passively cooperates in receiving and feeding back signals and does not actively initiate requests.

[0115] For example, the wireless access device sends the target sensing capability parameters that match the sensing permissions of the terminal device to the terminal device; the terminal device initiates a sensing task based on the received target sensing capability parameters to trigger the wireless access device to perform sensing processing. For example, a smart switch (STA) needs to determine whether "there is someone in the room" and needs to use the AP to determine whether "there is someone in the room" so as to automatically control the light switch.

[0116] In the aforementioned sensing processing method, sensing permission configuration information sent by the control terminal is received. This information represents the configuration of sensing permissions for the terminal device. Then, based on the sensing permission configuration information, target sensing capability parameters matching the terminal device's sensing permissions are determined. These target sensing capability parameters represent the parameters corresponding to the sensing capabilities authorized by the wireless access device for use by the terminal device. Finally, the target sensing capability parameters are sent to the terminal device, enabling it to perform sensing processing based on these parameters. In this way, by using the sensing permission configuration information sent by the control terminal to determine the target sensing capability parameters matching the terminal device's sensing permissions and sending these parameters to the terminal device, the method achieves the goal of sending different target sensing capability parameters to terminal devices with different sensing permissions. This ensures the effectiveness of on-demand access to the wireless access device's sensing capabilities, avoids the abuse of sensing capabilities leading to low security in sensing processing, and ensures that only terminal devices with configured sensing permissions can participate in sensing processing, thereby improving the security of sensing processing.

[0117] In an exemplary embodiment, step S202 above, which determines the target perception capability parameters matching the perception permissions of the terminal device based on the perception permission configuration information, specifically includes the following: receiving an association request frame sent by the terminal device; calling the perception permission configuration information based on the association request frame to determine the perception permissions of the terminal device; and determining the target perception capability parameters matching the perception permissions of the terminal device.

[0118] Among them, the Association Request frame is used to request the acquisition of target perception capability parameters that match the perception permissions of the terminal device.

[0119] For example, the terminal device generates an association request frame and sends it to the wireless access device. The wireless access device responds to the association request frame, obtains the terminal device's device ID, and based on the device ID, queries the perception permission configuration information to obtain the perception permission corresponding to the terminal device's device ID, which is then used as the terminal device's perception permission. Next, it continues to query the perception permission configuration information to obtain the target perception capability parameters matching the terminal device's perception permission. For details, please refer to... Figure 5 .

[0120] In this embodiment, an association request frame sent by a terminal device is first received; then, based on the association request frame, the perception permission configuration information is invoked to determine the perception permission of the terminal device; finally, the target perception capability parameter matching the perception permission of the terminal device is determined; in this way, the purpose of configuring different target perception capability parameters for terminal devices with different perception permissions is achieved, avoiding the abuse of perception capabilities and thus improving the security of perception processing.

[0121] In an exemplary embodiment, step S203 above, sending the target perception capability parameters to the terminal device, specifically includes the following: generating an association response frame corresponding to the association request frame; the association response frame carrying the target perception capability parameters; sending the association response frame to the terminal device, so that the terminal device updates the stored target perception capability identifier to the target perception capability parameters, and performs perception processing based on the target perception capability parameters.

[0122] Among them, the association response frame refers to the association response frame, which carries target perception capability parameters that match the perception permissions of the terminal device.

[0123] Among them, the target perception capability identifier refers to the identifier of the perception capability of the wireless access device, such as the perception capability name, which is used to identify the perception capability that the wireless access device can perform, so that the terminal device can determine which wireless access devices can perform perception tasks.

[0124] It should be noted that the target perception capability identifier stored by the terminal device is obtained based on the detection response frame returned by the wireless access device after the terminal device sends a detection request frame to the wireless access device.

[0125] For example, the wireless access device generates an association response frame corresponding to the association request frame and carrying the target perception capability parameters based on the target perception capability parameters that match the perception permissions of the terminal device, and sends the association response frame to the terminal device; the terminal device updates the locally stored target perception capability identifier to the target perception capability parameters, and performs perception processing based on the target perception capability parameters, such as initiating or being invoked for perception measurement, as detailed in [reference needed]. Figure 5 .

[0126] In this embodiment, an association response frame corresponding to the association request frame and carrying the target perception capability parameters is generated, and the association response frame is sent to the terminal device. This causes the terminal device to update the stored target perception capability identifier to the target perception capability parameters and perform perception processing based on the target perception capability parameters. In this way, the purpose of sending different target perception capability parameters to terminal devices with different perception permissions is achieved, which enables authorized terminal devices to call the perception capabilities of the wireless access device as needed, thereby improving the security of perception processing.

[0127] In an exemplary embodiment, before receiving the association request frame sent by the terminal device, the method further includes: receiving the authentication request frame sent by the terminal device; performing authentication processing on the terminal device based on the authentication request frame to obtain an authentication response frame corresponding to the authentication request frame; and sending the authentication response frame to the terminal device.

[0128] The authentication request frame is used to request the wireless access device to perform authentication processing on the terminal device, such as identity verification.

[0129] The authentication response frame is used to carry the authentication processing result for the terminal device.

[0130] For example, the terminal device generates an authentication request frame and sends it to the wireless access device. Based on the received authentication request frame, the wireless access device performs authentication processing on the terminal device, such as verifying whether the terminal device's identity meets the requirements, and obtains an authentication result (e.g., authentication passed or failed). Based on the authentication result, it generates an authentication response frame corresponding to the authentication request frame, which carries the authentication result; and sends the authentication response frame to the terminal device. See [specific details omitted]. Figure 5 .

[0131] In this embodiment, an authentication request frame sent by the terminal device is first received. Then, based on the authentication request frame, the terminal device is authenticated to obtain an authentication response frame corresponding to the authentication request frame. Finally, the authentication response frame is sent to the terminal device. In this way, the purpose of authenticating the terminal device is achieved before sending the target perception capability parameters that match the perception permissions of the terminal device to the terminal device, which is conducive to further improving the security of perception processing.

[0132] In an exemplary embodiment, before receiving the authentication request frame sent by the terminal device, the method further includes: receiving a probe request frame sent by the terminal device; based on the probe request frame, invoking perception permission configuration information to determine the target perception capability identifier of the wireless access device; generating a probe response frame corresponding to the probe request frame; the probe response frame carrying the target perception capability identifier; sending the probe response frame to the terminal device, causing the terminal device to store the target perception capability identifier, and sending an authentication request frame to the corresponding wireless access device based on the target perception capability identifier.

[0133] Among them, the probe request frame refers to the Probe Request frame, which is used to request the target sensing capability identifier of the wireless access device.

[0134] The perception permission configuration information also includes the target perception capability identifier of the wireless access device. The target perception capability identifier of the wireless access device refers to the identifier of the perception capability that the wireless access device can perform, such as the perception capability name.

[0135] Among them, the probe response frame refers to the probe response frame, which carries the target sensing capability identifier of the wireless access device.

[0136] Specifically, sending an authentication request frame to the corresponding wireless access device based on the target perception capability identifier means that the terminal device determines the target wireless access device that can perform the perception task to be initiated by the terminal device from among multiple wireless access devices based on the target perception capability identifier, and sends an authentication request frame to the target wireless access device.

[0137] For example, the terminal device generates a probe request frame and sends it to the wireless access device. The wireless access device responds to the probe request frame, queries the sensing permission configuration information, and obtains the target sensing capability identifier of the wireless access device. Then, based on the target sensing capability identifier, it generates a probe response frame corresponding to the probe request frame and carrying the target sensing capability identifier. Finally, it sends the probe response frame to the terminal device. The terminal device stores the received target sensing capability identifier and, based on the target sensing capability identifier, determines from multiple wireless access devices the target wireless access device capable of performing the sensing task to be initiated by the terminal device. Then, it sends an authentication request frame to the target wireless access device. See [link to details]. Figure 5 .

[0138] In this embodiment, a probe request frame sent by the terminal device is first received. Then, based on the probe request frame, the perception permission configuration information is invoked to determine the target perception capability identifier of the wireless access device. Next, a probe response frame corresponding to the probe request frame and carrying the target perception capability identifier is generated. Finally, the probe response frame is sent to the terminal device, enabling the terminal device to store the target perception capability identifier and send an authentication request frame to the corresponding wireless access device based on the target perception capability identifier. In this way, the purpose of sending the corresponding target perception capability identifier to the terminal device before authenticating the terminal device is achieved. This facilitates the terminal device to select the appropriate wireless access device and initiate the corresponding perception request based on the target perception capability identifier, avoiding the situation where the wireless access device receives a large number of invalid perception requests, and further improving the security of perception processing.

[0139] In an exemplary embodiment, after sending the target perception capability parameters to the terminal device, step S203 further includes the following: when the perception task of the terminal device is completed or the perception permission of the terminal device expires, a deassociation frame is sent to the terminal device to release the perception permission of the terminal device.

[0140] Among them, perception tasks can refer to distance measurement tasks, angle measurement tasks, speed measurement tasks, motion trajectory measurement tasks, spatial number detection tasks, human presence detection tasks, intrusion detection tasks, fall detection tasks, breathing detection tasks, etc.

[0141] Among them, the completion of the sensing task by the terminal device refers to the invocation of the wireless access device to complete the sensing task.

[0142] Among them, the expiration of the terminal device's perception permission refers to the expiration of the validity period (e.g., 5 minutes) of the terminal device's perception permission.

[0143] Among them, the disassociation frame is used to remove the terminal device's perception permission from the state.

[0144] Among them, "removing the sensing permission from the terminal device" means resetting the sensing permission of the terminal device to an inactive state, that is, the terminal device has not obtained sensing permission.

[0145] For example, the wireless access device detects in real time whether the terminal device's sensing task has been completed. If the sensing task of the terminal device is detected to be completed, the device generates a deassociation frame and sends the deassociation frame to the terminal device. The terminal device responds to the deassociation frame and cancels its sensing permission activation state.

[0146] For example, the wireless access device detects in real time whether the terminal device's sensing permissions have expired. If the device detects that the terminal device's sensing permissions have expired, it generates a deassociation frame and sends the deassociation frame to the terminal device. The terminal device responds to the deassociation frame, revoking its own sensing permissions.

[0147] In this embodiment, when the terminal device completes its sensing task or the terminal device's sensing permission expires, a deassociation frame is sent to the terminal device to remove the terminal device's sensing permission from being active. This helps to prevent the sensing capability from being abused and further improves the security of sensing processing.

[0148] In an exemplary embodiment, the perception processing method of this application further includes the following: when a terminal device requests an update of perception permissions, receiving updated perception permission configuration information sent by a control terminal; the control terminal is used to receive the updated perception permission configuration information sent by an authorization platform; the authorization platform is used to perform authentication processing on the terminal device based on the perception permission update request sent by the terminal device, and generate updated perception permission configuration information; when the terminal device is not associated with a wireless access device, receiving a first association request frame sent by the terminal device; based on the first association request frame, calling the updated perception permission configuration information to determine a first updated perception capability parameter corresponding to the first updated perception permission of the terminal device; generating a first association response frame corresponding to the first association request frame; the first association response frame carries the first updated perception capability parameter; sending the first association response frame to the terminal device, so that the terminal device performs perception processing based on the first updated perception capability parameter.

[0149] Before initiating a sensing task, the terminal device needs to obtain the corresponding sensing permissions. If it does not currently have the corresponding sensing permissions, it needs to request an update of the sensing permissions.

[0150] The authorization platform refers to a third-party authorization platform used to generate updated perception permission configuration information based on the perception permission update request sent by the terminal device.

[0151] Among them, the authentication process for terminal devices refers to determining whether the identity of the terminal device meets the requirements.

[0152] For example, when a terminal device requests an update to its perception permissions, the terminal device generates a perception permission update request and sends it to the authorization platform. Based on the perception permission update request, the authorization platform authenticates the terminal device. Upon successful authentication, it generates updated perception permission configuration information and sends it to the control terminal. The control terminal then sends the received updated perception permission configuration information to the wireless access device. After receiving the updated perception permission configuration information, the wireless access device first determines whether the terminal device is associated with the wireless access device. If the terminal device is not associated with the wireless access device, it receives a first association request frame sent by the terminal device. Then, based on the first association request frame, it queries the updated perception permission configuration information to obtain the updated perception permission corresponding to the terminal device's device identifier, which serves as the terminal device's first updated perception permission. Next, it queries the updated perception permission configuration information to obtain the first updated perception capability parameters corresponding to the terminal device's first updated perception permission. Then, based on the first updated perception capability parameters corresponding to the terminal device's first updated perception permission, it generates a first association response frame corresponding to the first association request frame and carrying the first updated perception capability parameters, and sends the first association response frame to the terminal device. After receiving the first association response frame, the terminal device performs perception processing based on the first updated perception capability parameters, such as initiating a perception measurement. (See details...) Figure 6 .

[0153] In this embodiment, when a terminal device requests an update to its perception permission, it needs to first undergo identity verification through an authorization platform. Then, the first updated perception capability parameters corresponding to the first updated perception permission of the terminal device are sent to the terminal device through the control terminal and the wireless access device. This achieves the purpose of calling perception capabilities on demand, avoids the abuse of perception capabilities, and further improves the security of perception processing.

[0154] In an exemplary embodiment, after receiving the updated perception permission configuration information sent by the control terminal, the method further includes the following: if the terminal device is associated with a wireless access device, receiving a first probe request frame sent by the terminal device; based on the first probe request frame, invoking the updated perception permission configuration information to determine the second updated perception capability parameter corresponding to the second updated perception permission of the terminal device; generating a first probe response frame corresponding to the first probe request frame; the first probe response frame carrying the second updated perception capability parameter; and sending the first probe response frame to the terminal device, so that the terminal device performs perception processing based on the second updated perception capability parameter.

[0155] For example, when a terminal device requests an update to its perception permissions, the terminal device generates a perception permission update request and sends it to the authorization platform. Based on the perception permission update request, the authorization platform authenticates the terminal device. Upon successful authentication, it generates updated perception permission configuration information and sends it to the control terminal. The control terminal then sends the received updated perception permission configuration information to the wireless access device. After receiving the updated perception permission configuration information, the wireless access device first determines whether the terminal device is associated with the wireless access device. If the terminal device is associated with the wireless access device, it receives the first probe request frame sent by the terminal device. Then, based on the first probe request frame, it queries the updated perception permission configuration information to obtain the updated perception permission corresponding to the terminal device's device identifier, which serves as the terminal device's second updated perception permission. Next, it queries the updated perception permission configuration information to obtain the second updated perception capability parameters corresponding to the terminal device's second updated perception permission. Then, based on the second updated perception capability parameters corresponding to the terminal device's second updated perception permission, it generates a first probe response frame corresponding to the first probe request frame and carrying the second updated perception capability parameters, and sends the first probe response frame to the terminal device. After receiving the first probe response frame, the terminal device performs perception processing based on the second updated perception capability parameters, such as initiating a perception measurement. (See details...) Figure 6 .

[0156] In this embodiment, when a terminal device requests an update to its perception permissions, it needs to first undergo identity verification through an authorization platform. Then, the second updated perception capability parameters corresponding to the second updated perception permissions of the terminal device are sent to the terminal device through the control terminal and the wireless access device. This achieves the purpose of calling perception capabilities on demand, avoids the abuse of perception capabilities, and further improves the security of perception processing.

[0157] In an exemplary embodiment, the perception processing method of this application further includes the following: when a wireless access device requests an update to its perception permission, receiving a target perception task sent by an application platform through a control terminal; selecting a target terminal device from among the terminal devices that matches the target perception task; sending a second detection request frame to the target terminal device; the second detection request frame carrying a third updated perception capability parameter corresponding to the target terminal device; receiving a second detection response frame returned by the target terminal device corresponding to the second detection request frame; if the perception capability of the target terminal device is found to meet the target perception task based on the second detection response frame, executing the target perception task to obtain a target perception result corresponding to the target perception task; and sending the target perception result to the application platform through the control terminal.

[0158] Among them, "wireless access device request to update perception permissions" refers to the wireless access device requesting to update the perception permissions of the terminal device (such as enabling signal reception and feedback functions) in order to cooperate with it to complete the corresponding target perception task.

[0159] Among them, target perception tasks can refer to tasks such as spatial people detection, human presence detection, intrusion detection, fall detection, and breathing detection.

[0160] Among them, the target terminal device that matches the target perception task refers to the terminal device that can cooperate with the wireless access device to complete the target perception task (such as the indoor intrusion detection task), specifically the terminal device that can participate in the target perception task.

[0161] The application platform refers to a third-party application platform used to send target perception tasks to the control terminal.

[0162] Among them, the third updated sensing capability parameter refers to the parameter corresponding to the sensing capability that the wireless access device wants the target terminal device to perform.

[0163] For example, when a wireless access device requests an update to its sensing permission, the application platform sends a target sensing task to the control terminal. The control terminal then sends the received target sensing task to the wireless access device. Based on the received target sensing task, the wireless access device selects a target terminal device from multiple terminal devices that matches the target sensing task, and determines the third updated sensing capability parameters corresponding to the target terminal device based on the target sensing task. Next, it generates a second probe request frame carrying the third updated sensing capability parameters corresponding to the target terminal device and sends the second probe request frame to the target terminal device. Based on the received second probe request frame, the target terminal device obtains the third updated sensing capability parameters, and then, based on the third updated sensing capability parameters, confirms that its sensing capability can satisfy the target sensing task. It then generates a second probe response frame corresponding to the second probe request frame and sends the second probe response frame to the wireless access device. Based on the second probe response frame, the wireless access device recognizes that the target terminal device's sensing capability satisfies the target sensing task, and then executes the target sensing task (when the target terminal device acts as a cooperative sensing device), obtains the target sensing result corresponding to the target sensing task (e.g., someone intruding indoors), and sends the target sensing result to the control terminal. The control unit sends the received target perception results to the application platform. (See details...) Figure 7 .

[0164] In this embodiment, when a wireless access device requests an update to its sensing permission, it is necessary to first filter out the target terminal devices that match the target sensing task, then send the second detection request frame to the target terminal device, and only execute the target sensing task when it is found that the sensing capability of the target terminal device meets the target sensing task. This makes the sensing process safer, further improves the security of sensing processing, and helps protect the sensing function.

[0165] In one exemplary embodiment, such as Figure 3 As shown, another perceptual processing method is provided, which is applied to... Figure 1 Taking a terminal device as an example, the explanation includes the following steps S301 to S302. Wherein:

[0166] Step S301: Receive target perception capability parameters sent by the wireless access device that match the perception permissions of the terminal device.

[0167] The wireless access device is used to receive perception permission configuration information sent by the control terminal, and to determine the target perception capability parameters based on the perception permission configuration information. The perception permission configuration information is used to characterize the configuration information of perception permissions for terminal devices. The target perception capability parameters are used to characterize the parameters corresponding to the perception capabilities that the wireless access device authorizes the terminal devices to use.

[0168] Step S302: Perform perception processing based on target perception capability parameters.

[0169] It should be noted that for the specific implementation of the sensing processing method applied to terminal devices, please refer to the specific implementation of the sensing processing method applied to wireless access devices, which will not be repeated here.

[0170] In the above-mentioned sensing processing method, the sensing permission configuration information sent by the control terminal is used to determine the target sensing capability parameters that match the sensing permissions of the terminal device, and the target sensing capability parameters are sent to the terminal device. This achieves the purpose of sending different target sensing capability parameters to terminal devices with different sensing permissions, ensuring the effect of calling the sensing capabilities of the wireless access device on demand, avoiding the abuse of sensing capabilities and the resulting low security of sensing processing, and ensuring that only terminal devices with configured sensing permissions can participate in sensing processing, thereby improving the security of sensing processing.

[0171] In one exemplary embodiment, such as Figure 4 As shown, another perceptual processing method is provided, which can be applied to... Figure 1 Taking a wireless access device as an example, the explanation includes the following steps S401 to S409. Wherein:

[0172] Step S401: Receive perception permission configuration information sent by the control terminal; the perception permission configuration information is used to represent the configuration information of perception permissions for the terminal device.

[0173] Step S402: Receive a probe request frame sent by the terminal device; based on the probe request frame, call the perception permission configuration information to determine the target perception capability identifier of the wireless access device.

[0174] Step S403: Generate a detection response frame corresponding to the detection request frame; the detection response frame carries a target perception capability identifier.

[0175] Step S404: Send the detection response frame to the terminal device, so that the terminal device stores the target perception capability identifier, and sends an authentication request frame to the corresponding wireless access device based on the target perception capability identifier.

[0176] Step S405: Receive the authentication request frame sent by the terminal device; perform authentication processing on the terminal device based on the authentication request frame to obtain the authentication response frame corresponding to the authentication request frame; send the authentication response frame to the terminal device.

[0177] Step S406: Receive an association request frame sent by the terminal device; based on the association request frame, call the perception permission configuration information to determine the perception permission of the terminal device; determine the target perception capability parameters that match the perception permission of the terminal device.

[0178] Step S407: Generate an associated response frame corresponding to the associated request frame; the associated response frame carries target perception capability parameters.

[0179] Step S408: Send the associated response frame to the terminal device, so that the terminal device updates the stored target perception capability identifier to the target perception capability parameter, and performs perception processing based on the target perception capability parameter.

[0180] Step S409: When the terminal device completes its sensing task or the terminal device's sensing permission expires, a deassociation frame is sent to the terminal device to deactivate the terminal device's sensing permission.

[0181] In the above-mentioned sensing processing method, the sensing permission configuration information sent by the control terminal is used to determine the target sensing capability parameters that match the sensing permissions of the terminal device, and the target sensing capability parameters are sent to the terminal device. This achieves the purpose of sending different target sensing capability parameters to terminal devices with different sensing permissions, ensuring the effect of calling the sensing capabilities of the wireless access device on demand, avoiding the abuse of sensing capabilities and the resulting low security of sensing processing, and ensuring that only terminal devices with configured sensing permissions can participate in sensing processing, thereby improving the security of sensing processing.

[0182] To more clearly illustrate the sensing processing method provided in the embodiments of this application, a specific embodiment is described below. In an exemplary embodiment, this application also provides a method for protecting WLAN sensing functions. Addressing the problem that sensing capabilities carried in 802.11bf Probe and (Re)Association frame transmissions are easily abused, this method sends different Sensing Capabilities and other sensing parameters to STAs with different sensing permissions, enabling on-demand access to the sensing capabilities of APs or STAs and preventing excessive resource consumption or unauthorized use. Based on the IEEE 802.11bf sensing framework, and utilizing fine-grained control over the values ​​of sensing-related attribute elements, the protection of sensing capabilities is achieved. The specific steps are as follows:

[0183] (1) The AC or network management system configures the perception permissions of WLAN server access points such as AP or PCP. When the STA accesses the AP, it cannot directly obtain the actual perception capability of the AP or PCP.

[0184] (2) If the STA wants to call the AP resources to initiate sensing, it must first obtain the relevant authorization, then adjust the sensing permissions of the STA, update the AP's sensing capabilities through the Probe or Association frame, thereby allowing the STA to initiate sensing measurement interaction;

[0185] (3) If the AP wants to perform a perception task, it must first select a suitable STA, adjust its perception permissions, update the AP's perception capabilities through the Probe frame, and then initiate a perception measurement interaction until the perception task is completed.

[0186] (4) When the perception authorization expires or the perception task is completed, the AP should proactively update its perception capabilities to the STA and stop the perception measurement interaction with the STA.

[0187] This application introduces the concept of sensing capability authorization, whereby the AP / PCP exposes different sensing capability parameters to different STAs at different connection stages, ensuring that only trusted terminals can participate in sensing. Detailed procedures are attached. Figure 5The key points are explained below: 1. When AP / PCP is enabled, the AC or network management system checks whether it supports sensing capabilities. If sensing capabilities are supported, the sensing capability permissions are further configured. 2. Sensing permissions include SensingCapabilities carried at different connection stages, proxy sensing capabilities (SBP Parameters), DMG sensing capabilities (such as supporting DMG SensingCapabilities, DMG Sensing Short Capabilities, etc.), DMG proxy sensing capabilities (such as supporting DMG SBPParameters), and the maximum allowed sensing time period. 3. The SensingCapabilities and other sensing parameter values ​​received by the same STA at different access stages may be different, restricting its access to AP / PCP sensing capabilities. 4. The Sensing Capabilities received by different STAs at the same stage may also be different, depending on the policy configured by the AC or network management system or the need for AP / PCP to initiate sensing tasks. 5. Sensing permissions can be dynamically configured, and can be updated to the STA after successful configuration.

[0188] It should be noted that, Figure 5 In this context, Probe Request refers to a probe request frame; Probe Response refers to a probe response frame; Sensing Capabilities refers to sensing capabilities; Authentication Request refers to an authentication request frame; Authentication Response refers to an authentication response frame; Association Request refers to an association request frame; and Association Response refers to an association response frame.

[0189] There are two methods to achieve real-time updates of sensing permissions: initiated by the STA or initiated by the AP / PCP. When a STA needs to use the AP or other STAs associated with the AP for sensing, it needs to request permissions. If this cannot be directly configured in the AC or network management system, a third-party platform is required to request sensing permissions, and then the third-party platform configures the AC or network management system. To complete sensing tasks, the AP can also proactively adjust the sensing permissions of some STAs, allowing STAs with sensing capabilities to participate in sensing as SRs. Furthermore, a STA can also call upon the sensing capabilities of other STAs, but it still needs to obtain authorization for those STAs' sensing capabilities. This authorization can be requested by the third-party platform from the SDK installed on the STA, which will not be elaborated here.

[0190] For details on how STAs can request updated permissions and initiate the perception process, please see the appendix. Figure 6 The key points are explained below:

[0191] (a) Before an STA can initiate a sensory interaction, it must obtain authorization through a third-party platform.

[0192] (b) The third-party platform configures the AP / PCP where the STA is located through the AC / network management system and configures the sensing parameters for the STA.

[0193] (c) Since the perception capability update can only be transmitted through the Probe or Association frame, the STA has two methods to obtain the updated configuration: if the STA has not yet been associated with the AP / PCP, it can directly initiate an Association Request and obtain the updated perception capability related parameters from it; if the STA has already been associated with the AP / PCP, it can initiate a Probe process to obtain the updated perception capability related parameters.

[0194] (d) When the STA initiates the perception interaction process, the AP / PCP still needs to check whether it has the corresponding perception permission configuration.

[0195] (e) Authorization can be accompanied by a time period parameter. After the expiration, the AP / PCP will actively initiate Disassociation. When the STA re-associates, it will update the perception capability parameters to the unauthorized state.

[0196] It should be noted that, Figure 6 In this context, Disassociation refers to the process of removing associative frames.

[0197] The method for AP / PCP to request updated permissions and initiate the perception process is attached. Figure 7 The key points are explained below:

[0198] (a) AP / PCP may also proactively initiate detection based on the needs of third-party applications or its own operation and maintenance.

[0199] (b) First, the STAs that need to participate in perception should be selected based on the needs of the perception task and the connectivity situation.

[0200] (c) Send Probe Requests to these STAs to update their perception capability parameters and confirm whether their perception capabilities meet the requirements.

[0201] (d) Initiate a perception measurement interaction until the perception task is completed, and update its perception capability parameters again via Probe Request.

[0202] (e) During the execution of a perception task, only STAs are allowed to participate in perception, but are not allowed to initiate perception unless they are authorized.

[0203] In addition, Figure 8 This paper introduces the application of this application in smart home services. Many users are reluctant to install cameras in their homes due to security and privacy concerns. WLAN-based sensing capabilities perfectly fill this gap, enabling services such as intrusion detection, fall detection, and respiratory detection. (Reference) Figure 8 User A uses WLAN sensing for security services. Their access point (AP) is placed in an information box in their study. A laptop, which is frequently used in the study, acts as a collaborative sensing STA (Stationary Targeting Unit) to establish sensing and measurement interactions and detect human activity in the study. User B's residence is next door to User A's. Due to the small size of User B's study and the limited wall thickness, parts of User B's study are within User A's coverage area. In this situation, if the sensing function of User B's device is not restricted, User B can also detect some things happening in User A's home. However, under the authorization mechanism described in this application, User B's STA cannot obtain sensing permissions. Even if they crack User A's WLAN access password, they cannot further utilize sensing to obtain information about User A's home.

[0204] The above embodiments can achieve the following technical effects: (1) control the release of WLAN device sensing capabilities such as AP, PCP, STA, etc., and protect them from being abused; (2) refine the management of WLAN sensing process and improve the availability of sensing-related services.

[0205] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages in other steps. It is understood that the steps in different embodiments can be freely combined as needed, and all non-contradictory solutions formed by such combinations are within the scope of protection of this application.
