The wireless sensing condition switching method provided by the embodiment of the application is described in detail below through some embodiments and application scenes thereof with reference to the accompanying drawings.

The apparatus according to various embodiments of the present application is as follows:

a first device: in the following embodiment, the first device may be: a device and/or a Sensing Function (Sensing Function) network element for performing a Sensing service prior to a Sensing handover.

A second device: the device for performing the perceived service after the perceived handover may be a terminal (UE), or a base station, or other devices with wireless signal receiving/transmitting capability, and may be one or more devices.

The device used to perform the perceived traffic prior to perceived handover may be a UE, a base station, or other wireless signal receiving/transmitting capable device, and may be one or more devices. For convenience of distinction, a device for performing a awareness service before an awareness switch may be hereinafter also referred to as a third device.

The network element of the awareness function may be a network function node in the core network and/or the radio access network (Radio Access Network, RAN) responsible for at least one function of awareness request processing, awareness resource scheduling, awareness information interaction, awareness data processing, etc., which may be based on an access and mobility management function (Access and Mobility Management Function, AMF) or a location management function (Location Management Function, LMF) upgrade in the existing 5G network, or may be other network function nodes or newly defined network function nodes.

The signaling interaction method between the third device (i.e. the device used for executing the sensing service before sensing the switching), the second device and the sensing function network element comprises the following steps:

1) Through the air port (Uu port): if one of the third device and the second device is a base station and the other is a UE, direct signaling interaction between the third device and the second device may be in this manner; in addition, if the network element with the sensing function is located at the RAN side, when the third device or the second device is UE, the signaling interaction between the third device or the second device and the network element with the sensing function may also use this manner.

2) Through the network: if the third device or the second device is a base station, the direct signaling interaction with the awareness function network element may take this form; in addition, if the third device and the second device are both base stations, the signaling interaction between the third device and the second device may also take this form.

3) Through air interface (Uu interface) and network: if the third device or the second device is UE, the signaling interaction between the third device and the network element with the sensing function may be performed in such a way that the UE needs to communicate with the access base station through an air interface (Uu interface) first, and then perform the signaling interaction through the network between the access base station and the network element with the sensing function.

4) Through side link (sidlink): if the third device and the second device are both UEs, direct signaling interaction between the third device and the second device may take this form.

5) Through an Xn interface: if the third device and the second device are both base stations, direct signaling interaction between the third device and the second device may take place in this way.

6) Permutation and combination of the above signaling interaction modes: namely, the signaling interaction among the third equipment, the second equipment and the perception function network element can also carry out indirect signaling interaction (forwarding) in a combination mode of any one or more of the signaling interactions; for example: the third device is UE and the second device is also UE, and one feasible way of signaling interaction between the second device and the network element with the sensing function is that the second device communicates with the third device through the sip link first, and then the third device communicates with the network and the network element with the sensing function through an air interface (Uu interface), so as to realize signaling interaction between the second device and the network element with the sensing function.

As shown in fig. 2, an embodiment of the present application provides a wireless sensing condition switching method 200, which may be performed by a first device, in other words, by software or hardware installed in the first device, the method including the following steps.

S202: the first device determines whether a handover of a device for performing a awareness service is required.

In the embodiment of the present application, the first device may be: a device (or called a third device) and/or a network element of a awareness function that is used to perform awareness traffic prior to an awareness switch.

Optionally, the first device mentioned in the various embodiments of the present application determines whether a device for performing a perceived service needs to be switched, including one of the following:

1) The first device autonomously determines whether a handover of a device for performing a awareness service is required.

For example, the first device is a device (or referred to as a third device) for performing a sensing service before sensing handover, and the third device autonomously determines whether handover of the device for performing the sensing service is required.

2) The first device determines whether to switch the device for executing the sensing service based on the received first request information, wherein the first request information is sent by the device for executing the sensing service before switching, and the device for executing the sensing service before switching determines whether to switch the device for executing the sensing service.

For example, the first device is a network element with a sensing function, and after determining whether to switch the device for executing the sensing service, the device for executing the sensing service (or referred to as a third device) before sensing the switching sends first request information to the network element with the sensing function, where the first request information is used to indicate whether to switch the device for executing the sensing service.

S204: in the case that it is determined that a device performing a perceived service needs to be switched, the first device performs a first operation, the first operation including: determining a second device for executing the perceived service after switching from the pre-switching device list; in the case that it is determined that the device performing the awareness service does not need to be switched, the first device performs a second operation including: the list of pre-switch devices is established or updated.

Optionally, the case that the device performing the awareness service needs to be switched includes: the device performing the awareness traffic (or referred to as the third device) before the handover satisfies at least one of:

1) The first indicator does not meet the requirement of the first threshold, and the first indicator comprises at least one of the following: sensing the measured quantity, sensing the result, sensing the relevant performance index of the measured quantity, and sensing the relevant performance index of the result. For example, the third device or the awareness functional network element compares the first indicator with the first threshold, the first indicator not meeting the requirement of the first threshold.

2) The resources for performing the awareness services are insufficient. For example, at least one of the time, frequency, antenna, power, etc. resources used by the third device to perform the perceived service may be partially or fully occupied by the high priority service and insufficient to continue to perform the perceived service.

3) Software or hardware problems occur. For example: the third device has insufficient electric quantity or has software and hardware faults.

It should be noted that, the "meeting" or "not meeting" the "requirement of the first threshold" mentioned in the various embodiments of the present application refers to whether the "meeting" or "not meeting" is within the range specified by the "first threshold". The meaning of "meeting" or "not meeting" the requirement of "first threshold" is slightly different depending on the content of "first index". For example, if the "first indicator" contains content such as signal strength/signal power (e.g., RSRP, RSSI) or signal quality (e.g., SNR), the "requirement that the first indicator meet the first threshold" may mean that the "first indicator is greater than the first threshold"; if the "first index" includes coordinates in the motion state parameter, etc., then the "the first index meets the requirement of the first threshold" may mean that the "the first index is located within the range specified by the first threshold"; if the "first index" includes the content such as variance in the related performance index, the "the first index meets the requirement of the first threshold" may mean that the "first index is smaller than the first threshold". The meaning of "second threshold", "third threshold", etc. is also the same.

In this embodiment, the first operation performed by the first device includes: and determining a second device for executing the perceived service after switching from the pre-switching device list. It can be understood that after the second device is determined, the first device may perform signaling interaction with the second device, so that the second device continues to perform the sensing service as the switched device; the third device may also exit, i.e. not execute the awareness traffic.

According to the wireless sensing switching method provided by the embodiment of the application, the first equipment determines whether equipment for executing sensing service needs to be switched or not, and under the condition that switching is needed, the first equipment determines second equipment for executing sensing service after switching from a pre-switching equipment list; the first device establishes or updates the list of pre-switch devices without requiring a switch. The embodiment of the application is beneficial to switching the equipment for executing the sensing service, avoids the interruption of the sensing service, ensures that the sensing service can be continuously executed, and improves the sensing quality of the sensing service.

On the basis of the embodiment shown in fig. 2, before the first device determines whether a handover of a device for performing a perceived service is required, the method further comprises: the first device obtains a first indicator, the first indicator comprising at least one of: sensing the measured quantity, sensing the result, sensing the relevant performance index of the measured quantity, and sensing the relevant performance index of the result.

In this embodiment, the method for the first device to obtain the first index may be: a device (or called a third device) for executing the sensing service before sensing the switching sends and receives the first sensing signal to obtain third data; the first device then performs signal processing and/or data processing on the third data, which may include one of:

1) And the third equipment performs first operation on the third data to obtain the first index.

Optionally, the third device sends the first index to a network element with a sensing function.

2) And the third equipment performs a second operation on the third data to obtain an intermediate measurement quantity/intermediate perception result, and sends the intermediate measurement quantity/intermediate perception result to a perception function network element, and the perception function network element performs a third operation on the intermediate measurement quantity/intermediate perception result to obtain the first index.

3) And the third equipment sends the third data to the sensing function network element, and the sensing function network element performs first operation on the third data to obtain the first index.

It should be noted that, in this embodiment, the third data is mentioned, and the first data and the second data are mentioned later, and in fact, these data may be the same type of data, but obtained by different devices; of course, these data may be different types of data.

Optionally, before determining whether the device for performing the perceived service needs to be switched, the method further includes: the first device compares the first index with a second threshold to determine whether a sensing adaptive adjustment is required; if the first index does not meet the requirement of the second threshold, performing sensing self-adaptive adjustment; wherein the sensing adaptation comprises adjusting a sensing signal parameter, the sensing signal parameter being used for executing the sensing service.

The perceptual adaptation comprises: adjusting at least one of the following of the perceived signal parameters: a signal waveform; a signal format; configuring a frequency domain; time domain configuration; configuring a airspace; energy domain configuration.

In the case of a first device performing a perceptual adaptive adjustment, the method further comprises: if the sensing signal parameter is adjusted to a limit value within an allowable range and the first index does not meet the requirement of the second threshold, executing the step of determining whether the device for executing the sensing service needs to be switched; or if the first index meets the requirement of the second threshold, executing the step of acquiring the first index.

In this embodiment, the awareness functional network element or the third device compares the first indicator with a third threshold: if the first index meets the requirement of the third threshold, a pre-switching device list is not established or updated; if the first indicator does not meet the requirement of the third threshold, a pre-switch device list is established or updated.

If the comparison (judgment) between the first index and the third threshold is performed by the third device, the third device reports the comparison (judgment) result to the network element with the sensing function after the comparison (judgment) is completed, or the third device only reports the situation that the first index meets the third threshold or the first index does not meet one of the third thresholds.

Optionally, establishing or updating the pre-switching device list mentioned in the various embodiments of the present application includes: the pre-switch device list is established or updated according to first information, wherein the first information comprises at least one of the following: sensing capability information of the device; perceived subscription information of the device: perceived license information of the device; location information of the device; sensing demand information; sensing priori information; context information is perceived.

On the basis of embodiment 200, the first operation includes one of: 1) Determining a second device for executing the perceived service after switching from the pre-switching device list; 2) And determining a candidate device list from the pre-switching device list, wherein the candidate device list comprises at least one candidate device. Optionally, after the embodiment is performed, the first device may further determine, from the candidate devices, a second device that performs the perceived service after the handover.

It may be appreciated that in each embodiment of the present application, after determining the second device, the first device may further perform signaling interaction with the second device, so that the second device continues to perform the sensing service as the switched device; the third device may also exit, i.e. not execute the awareness traffic.

In various embodiments of the present application, after the first operation is performed by the first device, the method further includes at least one of:

For example, the first device is a sensing function network element, the sensing function network element determines a second device that performs a sensing service after switching, and the sensing function network element sends a first signaling to the second device, where the first signaling is used to notify that a device that receives the first signaling is selected as the second device.

2) Sending a second signaling to the candidate device; wherein the device receiving the second signaling is a candidate device.

For example, the first device is a sensing function network element, the sensing function network element determines a candidate device list, and the sensing function network element sends a second signaling to the candidate devices in the candidate device list, where the second signaling is used to notify that the device that receives the second signaling is selected as the candidate device in the candidate list.

It will be appreciated that the candidate devices in the candidate device list are typically a plurality, and that in actual use, the first device may determine from the plurality of candidate devices one or more second devices for performing the perceived task.

In this embodiment, the second device determined from the candidate devices satisfies at least one of:

1) The corresponding second index meets the requirement of the fourth threshold.

2) The corresponding second index better meets the requirement of the first threshold than the first index, and the difference or the proportion value of the second index and the first index meets the requirement of the fifth threshold.

It should be noted that, the "meeting" or "not meeting" the "requirement of the second threshold" mentioned in the various embodiments of the present application refers to whether the "meeting" or "not meeting" is within the range specified by the "second threshold". The meaning of "meeting" or "not meeting" the requirements of "second threshold" is slightly different depending on the content of "first index". For example, if the "first indicator" contains content such as signal strength/signal power (e.g., RSRP, RSSI) or signal quality (e.g., SNR), then the "requirement that the first indicator meet the second threshold" means that the "first indicator is greater than the second threshold"; if the first index includes coordinates in the motion state parameter, etc., the "the first index meets the requirement of the second threshold" means that the first index is located in the range specified by the second threshold "; if the first index includes the variance and other contents in the related performance index, the requirement that the first index meets the second threshold means that the first index is smaller than the second threshold. The same is true of the meaning of "first threshold", "third threshold", etc. described below.

In this case, step 4 is entered.

In order to describe the wireless sensing condition switching method provided by the embodiment of the present application in detail, the following description will be made with reference to several specific embodiments.

Example 1

In this embodiment, the motion of the perception object causes a signal quality degradation triggering the perception switch.

As shown in fig. 3, the sensing object (for example, a car) moves along a certain path, and the sensing node a (for example, the base station self-receiving device corresponds to the third device) senses (measures distance/speed/angle) the sensing object. At time n, the perceptibility of the perceived object by the perceived node a is lower than a preset threshold (corresponding to the first threshold of the previous technical scheme section). Under the scheduling coordination of the network element with the sensing function, according to the wireless sensing switching method introduced by the previous embodiment, the sensing node B (taking the spontaneous self-reception of the base station as an example, corresponding to the second device before) is selected to switch and execute sensing, and the sensing node B starts sensing the sensing object at the time of n+1.

Example two

In this embodiment, the motion of the terminal device performing the awareness traffic causes a signal quality degradation triggering the awareness switch.

As shown in fig. 4, the sensing node a (for example, UE self-receiving, corresponding to the third device in the foregoing) senses the sensing object (for example, car). The motion of the sensing node A from the time n-1 to the time n is further and further away from the sensing object, so that the sensing performance of the sensing node A on the sensing object is lower than a preset threshold (corresponding to the first threshold of the technical scheme part). Under the scheduling coordination of the network element with the sensing function, according to the wireless sensing switching method introduced in the foregoing embodiment, a sensing node B (for example, UE self-receiving, corresponding to the foregoing second device) is selected to switch to perform sensing. The motion of the sensing node B causes the sensing node B to be closer and closer to the sensing object, thereby being suitable for performing sensing services.

Example III

In this embodiment, the perceived object movement across cells triggers perceived handover.

As shown in fig. 5, the sensing node a (for example, the base station autonomously self-receives, and corresponds to the third device described above) senses the sensing object (for example, the car). At time n, the sensing node a or the sensing function network element determines that the location of the sensing object exceeds (or is about to exceed) the coverage area of the sensing node a (the signal quality is not necessarily poor). Under the scheduling coordination of the network elements with sensing functions, the sensing node B (for example, the base station self-receiving, corresponding to the second device) is selected to perform sensing on the sensing object after switching according to the motion track of the sensing object, so as to obtain the optimal sensing performance.

Example IV

In this embodiment, the vertical handover is performed according to the speed of the perception object, and the handover is performed from the micro base station to the macro base station.

As shown in fig. 6, the sensing node a (for example, the micro base station spontaneously self-receives, corresponding to the foregoing third device) senses the sensing object (for example, the automobile). At the time n, the sensing node A or the sensing function network element judges that the movement speed of the sensing object is increased, and the coverage area of the sensing node A is quickly exceeded. Under the scheduling coordination of the sensing function network element, a sensing node B (taking macro base station self-receiving as an example, corresponding to the second device) is selected for performing sensing on the sensing object after switching.
