Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.

In the following description, reference is made to "some embodiments" which describe a subset of all possible embodiments, but it is understood that "some embodiments" may be the same subset or different subsets of all possible embodiments, and may be combined with each other without conflict.

It should be noted that the terms "first \ second \ third" are used merely to distinguish similar objects and do not represent a specific ordering for the objects, and it should be understood that "first \ second \ third" may be interchanged under certain ordering or sequence if so permitted so that the embodiments of the present application described herein can be implemented in other orders than that shown or described herein.

Before further detailed description of the embodiments of the present application, first, a description is given of related technologies related to the embodiments of the present application:

Wi-Fi Sensing (Wi-Fi Sensing) technology, also known as wireless Sensing technology, is a new behavior Sensing technology, and can use existing Wi-Fi signals to realize motion detection, gesture recognition and biometric measurement based on existing Wi-Fi networks and devices in the environment. For Wi-Fi perception technology, changes in the environment caused by the motion of objects, pets and people can be detected based on CSI data or based on Radar data without the need for the detected object to wear any equipment. By implementing the Wi-Fi sensing technology, the system can provide more intelligent and richer application in the fields of intelligent home, intrusion detection, medical care, intelligent remote nursing and the like.

In the existing Wi-Fi aware process (or referred to as a wireless aware process), respective roles of different participating devices in the wireless aware process are determined through a negotiation stage, and then a specific aware measurement process is performed. From the perspective of an establishment mode, the wireless sensing process comprises an initiating device and a responding device; from the function of the execution process, the wireless sensing process comprises a sender and a receiver, the sender sends a sensing data packet to the receiver according to a pre-agreed mode, and the receiver measures the received sensing data packet and processes the sensing data packet according to the measurement result to obtain a final sensing result.

In the sensing measurement process, the initiating device may serve as a receiver to receive sensing data packets sent by multiple senders, and at this time, the wireless sensing process in the initiating device occupies more central processing unit resources. However, there are other normal application processes in the initiating device itself, for example, the initiating device may be a mobile phone, a smart tv, a tablet computer, etc., and these devices usually run more or less applications. Thus, for the initiating device, on the one hand, more processor resources may be allocated to the wireless aware process if there are fewer running applications or in an idle state, but if there are more running applications, the consumption of processor resources may deteriorate the overall performance, the latency of the aware result. On the other hand, if the sensing measurement precision or accuracy is poor, the initiating device as the sender may need to be converted into a receiver to receive the CSI data sent by the multiple devices, and then the CSI devices sent by the multiple devices are used for performing data fusion calculation, so as to improve the sensing measurement precision and accuracy.

As can be seen from the above, for the wireless aware process, the same device may be subject to role switching, from the initiating device to the recipient, or from the recipient to the initiating device.

In a related technology, a negotiation process of wireless sensing is analyzed, and it is proposed that when there are multiple responding devices, a single signaling can be sent by triggering a frame mechanism to reduce a large amount of signaling overhead caused by multiple negotiation processes. In another related technology, a threshold-based measurement and reporting mechanism is proposed, in the process establishment phase, both parties negotiate to determine to use the threshold-based measurement mechanism, in the measurement phase, measurement is performed, and in the reporting phase, a report is sent according to a threshold condition.

However, with the support of the related art, referring to fig. 1, a flowchart of a wireless sensing control method provided in the related art is shown. As shown in fig. 1, in order to realize the aforementioned role switching, the following steps must be passed:

s101: the initiating device sends a request message for ending the sensing process to the responding device.

It should be noted that, in the related art, in order to implement role switching, it is necessary to end the current wireless sensing process, and then initiate a new wireless sensing process according to the switched related parameters. Therefore, the initiating device needs to send a request message for ending the wireless sensing process to the responding device to inform the responding device to end the current wireless sensing process.

S102: the response equipment sends a response message of finishing the perception process to the initiating equipment.

It should be noted that, after receiving the end sensing process message, the response device needs to send a corresponding response message (i.e., an end sensing process response message) to the initiating device to end the current wireless sensing process.

S103: the initiating device sends a new aware process request message to the responding device again.

It should be noted that, the initiating device determines the relevant parameters according to the converted role, regenerates a new sensing process request message, and sends the generated new sensing process request message to the responding device.

S104: the response device judges whether the execution is possible or not, and sends a sensing process response message to the initiating device.

For the step S104, if the judgment result is yes, the process is ended; if the judgment result is no, step S105 is performed.

It should be noted that, after receiving the new sensing process request message, the responding device replies with a response message to inform the initiating device whether it can execute. Here, if the responder device confirms that it can perform, the initiator device and the responder device establish a new radio aware process, thereby completing role switching.

S105: the initiating device adjusts the parameters and returns to execute step S103.

It should be noted that, if the responding device does not support establishing a new wireless awareness process with the initiating device, the initiating device needs to adjust parameters, and repeatedly execute steps S103 and S104 until a new wireless awareness process is successfully established.

Thus, the whole role switching process can be completed through the steps, but the delay or interruption of the sensing process is caused, and the signaling overhead between the initiating device and the responding device is increased, so that the network resource consumption is caused, and the throughput of the effective data of the network is reduced.

Based on this, an embodiment of the present application provides a wireless sensing control method, which is applied to a first device and a second device, and a wireless sensing process exists between the first device and the second device, and the basic idea of the method is as follows: at the first equipment side, determining the state information of the first equipment; if the state information of the first equipment meets the preset condition, sending a role switching request message to the second equipment; and receiving a role switching response message sent by the second equipment, and determining whether the first equipment is switched from the first role to the second role in the wireless sensing process according to the role switching response message. On the second equipment side, a wireless sensing process exists between the first equipment and the second equipment, and a role switching request sent by the first equipment is received; generating a role switching response message according to the role switching request; the role switching response message is used for indicating whether the second equipment agrees to switch from the second role to the first role in the wireless perception process; and sending the role switching response message to the first equipment. Therefore, if the state information of the first device meets the preset condition, the first device can send a role switching request message to the second device, and determine whether to perform role switching according to the response of the second device, that is, the method provided by the embodiment of the application can adjust and control the ongoing sensing process, thereby reducing signaling overhead, ensuring the fluency and continuity of the ongoing sensing process, and improving the precision and accuracy of the sensing service.

Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

In an embodiment of the present application, refer to fig. 2, which shows a flowchart of a wireless sensing control method provided in an embodiment of the present application. As shown in fig. 2, the method may include:

s201: status information of the first device is determined.

It should be noted that the wireless awareness control method provided in the embodiment of the present application is applied to the first device, and a wireless awareness process exists between the first device and the second device. Here, the first device refers to an initiating device of a wireless aware process, and the second device refers to a responding device of the wireless aware process. Specifically, the first device may be any computing device capable of exchanging data through Wi-Fi technology, such as a Personal Computer (PC), a notebook Computer, a Personal Digital Assistant (PDA), a Portable Multimedia Player (PMP), a playstation Portable (PSP), a Wireless Communication Terminal (Wireless Communication Terminal), a Smart Phone (Smart Phone), a television, a Virtual Reality device (Virtual Reality, VR), an Augmented Reality device (AR), a Mixed Reality device (Mixed Reality, MR), smart Glasses (Smart Glasses), and the like.

It should be noted that the wireless sensing technology is a technology for implementing wireless sensing by using Wi-Fi technology, and the specific process is as follows: the first device establishes a wireless awareness process with the second device in which one of the first device and the second device acts as a sender and the other acts as a receiver. The sender sends the sensing data packet to the receiver according to preset and agreed sending parameters, and the receiver obtains a wireless sensing result by measuring information such as signal strength, phase and the like of the received sensing data packet. In addition, since the wireless sensing result is required on the side of the first device, if the second device is a receiver, the second device also needs to transmit the obtained wireless sensing result to the first device.

Specifically, for a first device as an initiating device, a wireless awareness procedure needs to be established with a second device. Thus, in some embodiments, the method may further comprise:

sending a process establishing request message to the second device;

the method comprises the steps that a wireless sensing process is established with second equipment under the condition that a process establishing response message sent by the second equipment is received and indicates that the second equipment agrees to establish the wireless sensing process; in the wireless sensing process, the first device takes a first role, and the second device takes a second role.

It should be noted that, when a wireless sensing process needs to be established, the first device sends a process establishment request message to the second device, and determines whether the second device agrees to establish the sensing process request according to a process establishment response message returned by the second device.

And if the process establishing response message indicates that the second equipment agrees to establish the wireless sensing process, the second equipment and the first equipment execute respective roles according to the negotiated parameters, namely the wireless sensing process is established between the first equipment and the second equipment. Herein, a role of the first device in the initially established wireless awareness process is referred to as a first role, and a role of the second device in the initially established wireless awareness process is referred to as a second role.

Here, the first role and the second role may be determined according to an actual application scenario, for example, the first role is a sender, and the second role is a receiver; or the first role is the receiver and the second role is the sender.

It should be further noted that, for example, the following parameters may be included in the setup procedure request message: (1) perceiving process identification; (2) The current request type parameter indicates that the request is an 'initial request'; (3) A role definition parameter for indicating which device is a receiver and which device is a sender; and (4) other relevant parameters.

In particular, if the role definition parameter defines that the second device is a sender of the wireless sensing process, other related parameters need to include specific sending parameters of the sensing data packet, such as initial sending time, sending frequency, bandwidth, data, interval time, and the like; if the role definition parameter defines that the second device is used as a receiver of the wireless sensing process, other related parameters need to include a specific sending parameter of the sensing data packet and a feedback parameter of the sensing result at the same time, and the feedback parameter of the sensing result may include a sending trigger mode (for example, sending at a fixed time, sending when receiving a request of the first device), sending time, and the like.

Of course, for convenience of subsequent role switching, no matter what role the second device is, other related parameters may also include both of these two parameters.

Further, in some embodiments, where the first device is a recipient, the method may further comprise:

receiving a sensing data packet sent by second equipment;

and carrying out perception measurement processing according to the received perception data packet to obtain a target perception result.

It should be noted that the first device may be a receiver, and at this time, the second device sends the sensing data packet to the first device at regular time, and the first device receives the sensing data packet, then measures the sensing data packet, and performs sensing calculation according to the measurement result to obtain a target sensing result. Here, the measurement and perception calculation process of the perception data packet is not the focus of the embodiment of the present application and will not be described herein too much.

Further, in some embodiments, in the case that the role of the first device is sender, the method may further include:

sending a sensing data packet to the second device;

and receiving a measurement report sent by the second equipment, and determining a target perception result according to the measurement report.

It should be noted that the first device may be a sender, and at this time, the first device sends the sensing data packet to the second device at regular time, so that the second device receives the sensing data packet, performs measurement and sensing calculation on the sensing data packet, and then transmits an obtained result to the first device in the form of a measurement report.

It should be noted that, for the receiver of the sensing packet, the sensing measurement process includes two processes: (1) measurement of sensory data packets; (2) And calculating according to the measurement result to obtain a target perception result. Here, the second device may measure only the sensing data packet, return the measurement result as a measurement report to the first device, and calculate the target sensing result according to the measurement result by the first device; or the second device may directly measure and calculate the sensing data packet to obtain a target sensing result, and then return the target sensing result as a measurement report to the first device.

Through the steps, the wireless sensing process is established between the first device and the second device, and in the normal execution process of the wireless sensing process, the first device can check the state information of the first device, so that role switching can be performed when necessary, and the service quality of the wireless sensing process is further ensured.

S202: and if the state information of the first equipment meets the preset condition, sending a role switching request message to the second equipment.

It should be noted that, since the first role and the second role are two opposite roles, the first device and the second device must perform role switching at the same time. Therefore, if the state information of the first device meets the preset condition, the first device needs to send a role switching request message to the second device, so as to negotiate the possibility of role switching with the second device.

Illustratively, the role switch request message may include the following parameters: (1) perceiving process identification; (2) The request type parameter indicates that the request is an update request; (3) A role definition parameter for indicating which device is a receiver and which device is a sender; and (4) other relevant parameters.

In particular, other relevant parameters may also include the start time of the role switch, or other adjustment information. And if the role switching request message is that the second device is expected to be switched from the sender to the receiver and the second device does not obtain the feedback parameter of the sensing result from the previous interaction process, other related parameters also need to contain the feedback parameter of the sensing result.

Further, in some embodiments, if the first role is a sender, the state information of the first device meets a preset condition, which may include: the processor resource occupation value of the first device is greater than a preset threshold value.

It should be noted that, for the sender, only the sensing data packet needs to be sent to the receiver periodically, so that the burden of calculation is small; however, for the receiver, measurement processing of various indexes needs to be performed on the received sensing data packet, and modeling needs to be performed according to the measurement result to obtain the sensing result, so that the calculation pressure is large.

Taking the first device as a mobile phone as an example, the mobile phone is in a dormant state originally, the computing resources of the processor are sufficient, and the mobile phone can be used as a receiver to execute a wireless sensing process; however, if a user opens a plurality of applications temporarily, the computing pressure of the processor suddenly rises, and if the user continues to be a receiver, a situation such as a jam occurs, which not only causes a delay and a flash-back of the wireless sensing process, but also deteriorates the normal use experience of the user. In such a scenario, it is desirable for the handset to be able to transition the sender from the recipient.

Therefore, if the state information of the first device indicates that the processor resource occupancy value of the first device is greater than the preset threshold value, it indicates that the computing resource in the first device is in shortage and the role switching is required.

Further, in some embodiments, if the first role is a sender, the state information of the first device meets a preset condition, which may include: and the evaluation index parameter value of the wireless sensing process does not reach the preset standard value.

It should be noted that, generally, the second device is temporarily used as the receiver only in the case where the first device cannot be used as the receiver (as in the foregoing scenario), but in this case, since the second device can only calculate the sensing result from the sensing packet transmitted by the "unique first device", the accuracy and precision of the sensing result are low. In such a scenario, it is necessary for the first device to change from a sender to a receiver, so that the first device can perform channel fusion calculation according to the sensing data packets sent by the "multiple second devices" to obtain a sensing result with higher precision/accuracy.

Therefore, in the case that the first device is the sender, if the state information of the first device indicates that the evaluation index parameter value of the wireless sensing process does not reach the preset standard value, it indicates that the first device is required to be used as the receiver for performing wireless sensing with higher accuracy, and therefore role switching is required. Here, the evaluation index parameter value refers to the precision or accuracy of the wireless sensing result.

Therefore, when the first device is in a state of needing role switching, the role switching request message can be sent to the second device, so that the service quality of the wireless sensing process can be better maintained.

S203: and receiving a role switching response message sent by the second equipment, and determining whether the first equipment is switched from the first role to the second role in the wireless sensing process according to the role switching response message.

It should be noted that, after the first device sends the role switching request message to the second device, the second device may determine whether to approve role switching according to its own state, so as to return a role switching response message to the first device. Thus, the first device can determine whether the first character can be switched to the second character according to the character switching response message.

In a specific scenario, the determining whether the first device is switched from the first role to the second role in the wireless sensing process may include:

controlling the first device to switch from the first role to the second role under the condition that the role switch response message indicates that the second device agrees to switch from the second role to the first role; or,

in the case where the role switch response message indicates that the second device refuses to switch from the second role to the first role, the wireless aware process is kept unchanged.

It should be noted that, according to the role switching response message, if the second device agrees to perform role switching, the first device may switch from the first role to the second role; if the second device refuses to perform role switching, the first device cannot perform role switching and needs to keep the original wireless sensing process.

In another specific scenario, the number of the second devices may be multiple, and in this case, the first device and all the second devices must perform role switching at the same time. In other words, even if any one of the second devices agrees to perform role switching, the final result may not be role switched. Therefore, in the case that the number of the second devices is two or more, the determining whether the first device is changed from the first role to the second role in the wireless sensing process may further include:

starting a timer;

when the timing duration of the timer does not reach a first preset duration and the role switching response message indicates that all the second devices agree to switch from the second role to the first role, sending a role switching confirmation message to all the second devices and controlling the first devices to switch from the first role to the second role; or,

and under the condition that the timing duration of the timer reaches a first preset duration and the role switching response message does not indicate that all the second devices do not agree to switch from the second role to the first role, keeping the wireless sensing process unchanged.

It should be noted that, in the case that the number of the second devices is plural, the confirmation mechanism may be introduced in consideration of information isolation between the second device and other second devices. Specifically, the first device starts a timer after issuing the role switching request message, and if the first device knows that all the second devices agree to perform role switching within a first preset time period, the first device sends a role switching confirmation message to all the second devices, so that the first device and all the second devices perform role switching; otherwise, if the first device knows that some second devices refuse to perform role switching or the first device does not receive responses from some second devices within the first preset time, the first device does not send a role switching confirmation message, so that the first device and all the second devices keep the original wireless sensing process.

In particular, a timer is not necessary, i.e. the first device may not take the time into account until all responses of the second device are obtained; in addition, the above method is also applicable to the case where there is only one second device.

In another specific scenario, for a part of the second devices that do not agree to perform role switching, the wireless aware process between the first device and the second devices may also be terminated, so that the first device and the second devices that agree to perform role switching may complete role switching in the wireless aware process. Therefore, in the case that the number of the second devices is two or more, the determining whether the first device is changed from the first role of the wireless sensing process to the second role of the wireless sensing process may further include:

under the condition that the role conversion response message indicates that one of the second devices agrees to convert the second role into the first role, sending a role conversion confirmation message to the second device to be processed, and controlling the first device to convert the first role into the second role; or,

and in the case that the role switching response message indicates that one of the second devices refuses to switch from the second role to the first role, sending a aware process termination message to the one of the second devices to terminate the wireless aware process between the first device and the one of the second devices.

It should be noted that, if one of the second devices agrees to perform role switching, the first device may send a role switching confirmation message to the second device, and the first device switches from the first role to the second role. And if one of the second devices refuses to perform role switching, the first device sends a perception process termination message to the second device so as to end the wireless perception process between the first device and one of the second devices.

In particular, the above method is also applicable to the case where there is only one second device.

It should be further noted that, in the foregoing, the first device and the second device may both agree to perform role switching, for example, the role switching request message carries a change time parameter, and then, after the first device determines that the second device agrees to perform role switching, the first device switches from the first role to the second role according to the change time parameter, and at the same time, the second device switches from the second role to the first role according to the change time parameter.

In the above processing procedure, if the first device successfully switches from the first role to the second role, the step of specifying the second role needs to be executed, for example:

and if the first equipment is converted from the receiver to the sender, stopping receiving the sensing data packet and the processing process, starting to send the sensing data packet to the first equipment, receiving the measurement report, and obtaining a target sensing result according to the measurement report.

And if the first equipment is converted from the sender to the receiver, stopping sending the sensing data packet and receiving the measurement report, starting receiving the sensing data packet, and performing sensing measurement processing on the sensing data packet to obtain a target sensing result.

In the foregoing, the first device may also send a process modification request message to the second device to adjust any parameter in the wireless sensing process, such as a data packet sending parameter, a measurement report sending parameter, and the like, without being limited to the specific regulation step of role switching.

In summary, the embodiments of the present application provide a method for controlling a sensing process, which can perform role switching without terminating an existing wireless sensing process, so as to improve the smoothness and continuity of the wireless sensing process, save signaling overhead, and increase the accuracy of a wireless sensing result.

The embodiment of the application provides a wireless sensing control method, which is applied to first equipment, a wireless sensing process exists between the first equipment and second equipment, and state information of the first equipment is determined; if the state information of the first equipment meets the preset condition, sending a role switching request message to the second equipment; and receiving a role switching response message sent by the second equipment, and determining whether the first equipment is switched from the first role to the second role in the wireless sensing process according to the role switching response message. Therefore, the method provided by the embodiment of the application can adjust and control the ongoing sensing process, thereby reducing signaling overhead and ensuring the continuity and fluency of the ongoing sensing process; the accuracy and precision of the sensing service are improved while the normal operation of the sensing service is ensured.

In another embodiment of the present application, refer to fig. 3, which shows a flowchart of another wireless sensing control method provided in the embodiment of the present application. As shown in fig. 3, the method may include:

s301: and receiving a role switching request message sent by the first equipment.

It should be noted that the wireless awareness control method provided in the embodiment of the present application is applied to the second device, and a wireless awareness process exists between the second device and the first device. Here, the first device refers to an initiating device of a wireless aware process, and the second device refers to a responding device of the wireless aware process. Specifically, the second device may be any computing device capable of exchanging data through Wi-Fi technology, such as a Personal Computer (PC), a notebook Computer, a Personal Digital Assistant (PDA), a Portable Multimedia Player (PMP), a playstation game (PSP), a Wireless Communication Terminal (Wireless Communication Terminal), a Smart Phone (Smart Phone), a television, a Virtual Reality device (Virtual Reality, VR), an Augmented Reality device (AR), a Mixed Reality device (Mixed Reality, MR), smart Glasses (Smart Glasses), and the like.

In the embodiment of the present application, the first device and the second device must first establish the wireless sensing process. Thus, in some embodiments, the method may further comprise:

receiving a process establishing request message sent by first equipment;

generating a process establishing response message according to the process establishing request message, and sending the process establishing response message to the first device; and

under the condition that the establishment process response message indicates that the second equipment agrees to establish the wireless sensing process, establishing the wireless sensing process with the first equipment; in the wireless sensing process, the first device takes a first role, and the second device takes a second role.

It should be noted that, after receiving the request message for establishing the process sent by the first device, the second device needs to determine whether to agree to establish the aware process with the first device, and further generates a response message for establishing the process. And if the second equipment agrees to establish the wireless sensing process, the first equipment and the second equipment establish the wireless sensing process after sending a process establishing response message to the first equipment. For consistency of illustration, in the established wireless awareness procedure, the role carried by the first device is referred to as a first role, and the role carried by the second device is referred to as a second role.

Specifically, in some embodiments, the second device is a sender, and the method may further include:

and the sensing data packet is sent to the first equipment, so that the first equipment determines a target sensing result according to the sensing data packet.

It should be noted that, in a case that the second device is a sender, the second device needs to send a sensing packet to the first device, so that the first device determines the target sensing result according to the sensing packet. In particular, the aforementioned process establishment request message may include a data packet transmission parameter, so that the second device transmits the sensing data packet according to the data packet transmission parameter.

Specifically, in some embodiments, the second device is a recipient, and the method may further include:

receiving a sensing data packet sent by first equipment, and performing sensing measurement processing on the received sensing data packet to generate a measurement report;

and sending the measurement report to the first device so that the first device determines a target perception result according to the measurement report.

It should be noted that, when the second device is a receiver, the second device needs to receive the sensing data packet sent by the first device, perform sensing measurement processing on the received sensing data packet, and return the result to the first device in the form of a measurement report.

Specifically, the aforementioned sensing process establishment request message may include a data packet sending parameter and a sending parameter of a measurement report, so that the second device receives a sensing data packet according to the data packet sending parameter and measures the received sensing data packet; and after the measurement report is generated, returning the measurement report to the first equipment according to the sending parameters of the measurement report.

It should be further noted that, after the first device and the second device establish the wireless awareness process, if the first device desires to perform role switching with the second device, the first device sends a role exchange request message to the second device. At this time, the second device needs to perform subsequent operations according to the received role exchange request message.

S302: and generating a role switching response message according to the role switching request message.

It should be noted that the second device generates a role switching response message according to the role switching request message. Here, the role transition response message is used to indicate whether the second device agrees to transition from the second role to the first role in the wireless awareness process.

S303: and sending the role switching response message to the first equipment.

It should be noted that, the second device sends a role switching response message to the first device to inform the first device whether it agrees to perform role switching.

In a specific scenario, after the sending the role switching response message to the first device, the method may further include:

under the condition that the role conversion response message indicates that the second device agrees to convert the second role into the first role, controlling the second device to convert the first role from the second role in the wireless perception process; or,

It should be noted that, if the second device agrees to perform role switching, after sending a role switching response message to the first device, the second device switches from the second role to the first role. Otherwise, if the second device refuses to perform role switching, the wireless sensing process is kept unchanged.

In another specific scenario, the first device and the plurality of second devices execute the wireless sensing process, and at this time, all the second devices are required to agree with role switching to execute the role switching process. In other words, even if a particular one of the second devices agrees to make a role switch, the end result may not be to make a role switch. Therefore, in case that the role switch response message indicates that the second device agrees to switch from the second role to the first role, the method may further include:

starting a timer;

if the timing duration of the timer does not reach a second preset duration and a role switching confirmation message sent by the first equipment is received, controlling the second equipment to switch from the second role to the first role; or,

and if the timing duration of the timer reaches a second preset duration and the role switching confirmation message sent by the first equipment is not received, keeping the wireless sensing process unchanged.

It should be noted that, after the second role sends the role switching response message, a timer may be started, and if the second device receives the role switching confirmation message sent by the first device within a second preset time period, the specific step of executing role switching is started; otherwise, if the second device fails to receive the role switching confirmation message sent by the second device within the second preset time duration, the original wireless sensing process is maintained. Here, a timer is not necessary.

In yet another specific scenario, a first device may select a second device to perform a role switch with the rejection to terminate the wireless-aware process. Therefore, in some embodiments, in the case that the role switch response message indicates that the second device refuses to switch from the second role to the first role, the method may further include:

receiving a sensing process termination message sent by first equipment;

and finishing the wireless sensing process based on the sensing process termination message.

It should be further noted that, after the second device refuses to perform role switching, a sensing process termination message sent by the first device may also be received, so that the second device terminates the wireless sensing process.

In the above processing procedure, if the second device is successfully switched from the second role to the first role, the step of designating the first role needs to be performed, for example:

and if the second equipment is converted from the sender to the receiver, stopping sending the sensing data packet, starting receiving the sensing data packet, generating a measurement report, and returning the measurement report to the first equipment.

And if the second equipment is converted from the receiver to the sender, stopping receiving the sensing data packet and processing, and starting to send the sensing data packet to the first equipment.

The embodiment of the application provides a wireless perception control method, which is applied to second equipment, a wireless perception process exists between first equipment and the second equipment, and a role switching request message sent by the first equipment is received; generating a role switching response message according to the role switching request message; the role switching response message is used for indicating whether the second equipment agrees to switch the second role to the first role in the wireless perception process; and sending the role switching response message to the first device. Therefore, under the condition that the wireless sensing process exists between the first equipment and the second equipment, the second equipment sends role switching response information to the first equipment after receiving the role switching request information of the first equipment so as to inform the second equipment whether to approve role switching, and the ongoing sensing process can be adjusted and controlled by the method, so that the operation continuity and the operation fluency of the wireless sensing service are improved, the signaling overhead is saved, and the precision and the accuracy of the sensing result are further improved.

In another embodiment of the present application, refer to fig. 4, which shows a detailed flowchart of a wireless sensing control method provided in an embodiment of the present application. As shown in fig. 4, the wireless sensing control method is applied to a wireless sensing control system including a first device (also referred to as Initiator) and a second device (also referred to as Responder), and may include:

s401: the first device sends a Sensing Session Request message to the candidate second devices.

It should be noted that, in order to establish the radio aware process, the Initiator sends a Sensing Session Request message (equivalent to the aforementioned establishment process Request message) to the candidate second device response.

Specifically, the parameters included in the Sensing Session Request message are shown in table 1.

S402: the second device sends a Sensing Session Response message to the first device.

It should be noted that, taking response 1 as an example, after receiving the Sensing Session Request message, if the response 1 agrees to establish the Sensing process, the message is locally saved and the Status Code value is set to Accepted, and if the Sensing process is Refused to be established, the message is locally saved and the Status Code value is set to referred.

Meanwhile, the Response 1 generates a Sensing Session Response message (equivalent to the aforementioned setup procedure Response message) and sends it to the Initiator, and the Sensing Session Response message includes a parameter Status Code.

S403: and if the Sensing Session Response message indicates that the second device agrees to establish the wireless Sensing process, establishing the wireless Sensing process between the first device and the second device.

It should be noted that, after receiving the Sensing Session Response message, if the value of the parameter Status Code therein is Accepted, the Initiator confirms that the Responder1 agrees to establish the radio Sensing process. At this time, the first device saves the response 1 as the confirmed Sensing process and the second device in a preset information table (generally referred to as a Sensing Operating Set information table).

Then, the first device and the second device execute the specific steps of wireless sensing according to the agreed parameters, namely, the first device and the second device establish a wireless sensing process.

It should be noted that, in a specific application scenario, an Initiator originally serving as a Receiver (equivalent to the foregoing sender) needs to receive sensing data packets sent by all responses, and measure and calculate the sensing data packets to obtain a target sensing result. However, because the processor load of the Initiator is heavy, when the computing task needs to be handed over to the Responder for sharing, the Initiator can change the current role to be Transmitter (equivalent to the aforementioned Receiver), each Responder is used as a Receiver, receives the sensing data packet sent by the Initiator, measures and calculates the sensing data packet to obtain the target sensing result, and sends the target sensing result back to the Initiator.

Or,

in another specific application scenario, the Initiator originally serves as a Transmitter, but needs to improve the sensing precision/sensing accuracy of the wireless sensing process, for example, channels between multiple responders and the Initiator need to be fused to improve the sensing precision and accuracy, the Initiator may change the current role to be a Receiver, and each Responder serves as a Transmitter to send a sensing data packet to the Initiator, so that the Initiator may obtain more channel condition information, and channels between different devices may be fused to improve the sensing precision and accuracy.

In both of the above two specific application scenarios, role switching between Initiator and Responder is involved, and to accomplish this, the following steps may be performed.

S404: the first device sends a Sensing Session Request message to the second device.

It is assumed that there are 3 second devices, which are Responder1, responder2 and Responder3. The Initiator transmits a Sensing Session Request message (equivalent to the aforementioned role switch Request message) to the response 1, response 2, and response 3.

Specifically, the way for the Initiator to send the Sensing Session Request message may include: and respectively sending independent messages to the three devices, or uniformly sending the messages to the three devices in a broadcasting or multicasting mode.

It should be noted that the parameters included in the Sensing Session Request message are shown in table 5.

TABLE 5

As shown in table 6, the Sensing Role may include one or two of the following parameters.

Among them, the setting rule of the Request Type is shown in table 7.

S405: the second device sends a Sensing Session Response message to the first device.

It should be noted that, for the response, when receiving the Sensing Session Request message and the value of the Request Type in the message is Update, it is necessary to confirm whether the response is a participant of the target Sensing process.

Taking response 1 as an example, after receiving a Sensing Session Request message, if the value of the Request Type in the message is Update, the response 1 checks whether the locally stored information has information corresponding to the value of the Sensing Session ID, so as to determine whether the information itself is a participant of the target Sensing process. If the information stored locally does not have the information corresponding to the value of the Sensing Session ID, the value of the parameter Status Code is set to be referred, and a corresponding Sensing Session Response message (equivalent to the aforementioned role change Response message) is generated.

If the information stored locally has information corresponding to the value of the Sensing Session ID and the Response 1 agrees to change the role, the value of the Status Code is set to Accepted, and a corresponding Sensing Session Response message is generated.

According to the above processing steps, all the servers can generate a Sensing Session Response message, and all the servers need to send the Sensing Session Response message to the Initiator.

S406: and under the condition that the second device agrees to perform role conversion, the second device is converted into the first role from the second role.

It should be noted that, for each response, if the role switching is agreed, corresponding operations need to be executed according to the value in the Sensing Session Request message, which is specifically described as follows:

(1) In the Sensing Session Request message, if the value of Transmitter in the Sensing Role is the address or identification of Initiator, or/and the value of Receiver is the address or identification of Receiver 1, then the Receiver 1 stops sending the Sensing data packet; and starting to execute: according to the Sensing TX Parameters, a response 1 receives a Sensing data packet sent by an Initiator, measures CSI data of a channel between the response 1 and the Initiator, and obtains a measurement report; according to the Report Configuration parameter, the response 1 sends the measurement Report to the Initiator.

(2) In the Sensing Session Request message, if the value of Transmitter in the Sensing Role is the address or identification of Responder1, or/and the value of Receiver is the address or identification of Initiator, responder1 stops receiving the Sensing data packet and the subsequent processing; and starting to execute: the response 1 sends the Sensing packet to the Initiator according to the Sensing TX Parameters parameter.

S407: and under the condition that the first equipment receives a Sensing Session Response message sent by the second equipment and the Sensing Session Response message indicates that the second equipment agrees to perform role conversion, the first equipment is converted from the first role to the second role.

Here, the execution sequence between step S406 and step S407 is not sequential, and after the first device executes step S404, the first device executes step S407; after the second device performs step S405, the second device performs step S406.

It should be noted that, after receiving the Sensing Session Response message sent by each Response, if the values of Status codes in the message are all Accepted, the Initiator indicates that the second device agrees to perform Role switching, and at this time, the Initiator performs corresponding operations according to the Sensing Role parameter, which is specifically described as follows:

(1) In the Sensing Session Request message, if the Initiator is updated as the Transmitter, stopping receiving the Sensing data packet and the subsequent processing; and starting to execute: according to Sensing TX Parameters, an Initiator sends a Sensing data packet to a response and receives a measurement report sent by the response to obtain a target Sensing result;

(2) In the Sensing Session Request message, if the Initiator is updated as the Receiver, stopping sending the Sensing data packet; and starting to execute: according to Sensing TX Parameters, an Initiator receives a Sensing data packet, and measures (generally, measures CSI data) and calculates the Sensing data packet to obtain a target Sensing result.

Here, S406 and S407 are performed substantially once by Initiator and each response.

The embodiment of the application provides a wireless sensing control method, and the specific implementation method of the embodiment is elaborated in detail through the embodiment, so that the wireless sensing control method of the embodiment of the application can adjust and control an ongoing sensing process, thereby not only improving the operation continuity and the operation fluency of a wireless sensing service, but also saving signaling overhead, and further improving the precision and the accuracy of a sensing result.

In still another embodiment of the present application, refer to fig. 5, which shows a detailed flowchart of another wireless sensing control method provided in this application embodiment.

S505: the second device sends a Sensing Session Response message to the first device, and starts a second timer when the second device agrees to perform role switching.

It should be noted that, in this embodiment of the application, when the Response agrees to perform role switching, the Response needs to start a second timer when the Response sends a Sensing Session Response message to the Initiator.

S506: before the timing duration of the first timer reaches a first preset duration, if the first device receives the Sensing Session Response messages sent by all the second devices and all the Sensing Session Response messages indicate that the second devices agree to perform role switching, the first device sends a Sensing Session Confirm message to the second devices and the first role is switched into the second role.

It should be noted that, within the predefined time T _ delay (i.e. the first preset time duration), if the Initiator receives all Response transmission Response messages, and the Status Code values in all the Response transmission Response messages are all Accepted, it is determined that all the second devices agree to perform the role switching. At this time, the Initiator needs to send a Sensing Session Confirm message to each response message, and starts to switch from the first role to the second role, for example, starts to send a Sensing data packet or starts to receive a Sensing data packet;

if no Sensing Session Response message of all the responses is received within a predefined time, or if the value of Status Code in all the messages is Accepted although the Sensing Session Response messages of all the responses are received, the Initiator does not send a Sensing Session Confirm message to the responses, thereby keeping the original Sensing process unchanged.

S507: before the timing duration of the second timer reaches a second preset duration, if the second device receives a Sensing Session Confirm message, the second device is switched from the second role to the first role.

Here, the execution sequence between step S506 and step S507 is not sequential, and after the first device executes step S504, the first device executes step S506; after the second device performs step S505, the second device performs step S507.

It should be noted that, within a predefined time T _ delay (i.e., a second preset time period), after receiving a Sensing Session Confirm message sent by an Initiator, the Responder switches from the second role to the first role, for example, starts to send a Sensing packet or starts to receive a Sensing packet;

within a predefined time T _ delay, if a Sensing Session Confirm message sent by the Initiator is not received, the original Sensing process is kept unchanged.

In yet another embodiment of the present application, refer to fig. 6, which shows a detailed flowchart of another wireless sensing control method provided in the embodiment of the present application. As shown in fig. 6, the wireless sensing control method is applied to a wireless sensing control system including a first device (also referred to as Initiator) and a second device (also referred to as Responder), and may include:

s601: the first device sends a Sensing Session Request message to the candidate second devices,

it should be noted that step 601 is the same as step 401, and is not described herein again.

S602: the second device sends a Sensing Session Response message to the first device.

It should be noted that step 602 is the same as step 402, and is not described herein again.

S603: and if the Sensing Session Response message indicates that the second device agrees to establish the wireless Sensing process, establishing the wireless Sensing process between the first device and the second device.

It should be noted that step 603 is the same as step 403, and is not described herein again.

S604: the first device sends a Sensing Session Request message to the second device.

It should be noted that step 604 is the same as step 404, and is not described herein again.

S605: the second device sends a Sensing Session Response message to the first device.

It should be noted that step 605 is the same as step 405, and is not described herein again.

S606: under the condition that the Sensing Session Response message indicates that the second device agrees to perform role switching, the first device sends a Sensing Session Confirm message to the second device, and the first role is switched to a second role; or, in a case that the Sensing Session Response message indicates that the second device refuses to perform role switching, the first device sends a Sensing Session Termination to the second device to end the wireless Sensing process of the second device.

It should be noted that, taking Response 1 as an example, if the value of Status Code in the Sensing Session Response message received by the Initiator is Accepted, it is determined that Response 1 agrees to perform role switching, at this time, the Initiator sends a Sensing Session Confirm message to the Initiator, and the Initiator switches from the first role to the second role.

If the value of Status Code in the received Sensing Session Response message is called, then it is confirmed that Response 1 refuses to perform role switching, at this time, the Initiator sends a Sensing Session Termination message to the Initiator, so as to end the wireless Sensing process between the Initiator and the Response 1.

S607: receiving a Sensing Session Confirm message under the condition that the second device agrees to perform role switching, and switching the second role to the first role; or, in the case that the second device refuses to perform role switching, receiving a Sensing Session Termination, and ending the wireless Sensing process.

Here, the execution sequence between step S606 and step S607 is not sequential, and after the second device executes step S604, the first device executes step S606; after the second device performs step S505, the second device performs step S607.

It should be noted that if the response 1 receives the Sensing Session Confirm message, the second role is switched to the first role.

If the response 1 receives the Sensing Session Termination message, the current Sensing process is stopped, for example, the Sensing data packet is stopped being sent, or the Sensing data packet and the measurement report are stopped being received.

It should be noted that, in addition to modifying the Sensing Role parameter, other parameters related to the Sensing process and contained in the initial Sensing Session Request may perform the Update process by setting the Request Type to Update.
