[0045] The method, apparatus, and storage medium for determining a sensing device provided by an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0046] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone.

[0047] The terms "first" and "second" in the specification and drawings of the present application are used to distinguish different objects or different processes for the same object, rather than to describe the specific order of the objects.

[0048] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include other steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products, or devices.

[0049] It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0050] As an important technology in communication networks, communication-sensing integration technology can enable two independent functions, namely, communication function and sensing function, to coexist in the same system through means such as signal joint design and / or hardware sharing. In this way, while ensuring high-speed communication, it is possible to utilize the communication system and the reference signals of the communication system to achieve the monitoring and tracking of sensing targets (for example, unknown objects and known objects). Therefore, communication-sensing integration technology can be used as a candidate technology for the sixth generation of mobile communication technology (6G).

[0051] Figure 1It is an application scenario diagram of communication and sensing integration. In this application scenario, the transmission modes of communication and sensing include the network device sensing mode and the terminal device sensing mode. For different transmission modes, the sending nodes and receiving nodes of the sensing signals are also different. For example, in the network device sensing mode, the first network device can send multiple sensing signals, and after being scattered by the environment or the sensing target, the first network device receives the multiple scattered sensing signals (i.e., echo signals). Another example is that in the network device sensing mode, the first network device can send multiple sensing signals, and after being scattered by the environment or the sensing target, the first network device and the second network device receive the multiple scattered echo signals. Another example is that in the network device sensing mode, the terminal device can send multiple sensing signals, and after being scattered by the environment or the sensing target, the network device receives the multiple scattered echo signals. Another example is that in the terminal device sensing mode, the network device can send multiple sensing signals, and after being scattered by the environment or the sensing target, the terminal device receives the multiple scattered echo signals. Another example is that in the terminal device sensing mode, the first terminal device can send multiple sensing signals, and after being scattered by the environment or the sensing target, the first terminal device and the second terminal device receive the multiple scattered echo signals. Another example is that in the terminal device sensing mode, the first terminal device can send multiple sensing signals, and after being scattered by the environment or the sensing target, the first terminal device receives the multiple scattered echo signals.

[0052] In a communication and sensing system, the network device can first determine the transmission mode of communication and sensing and determine the uplink and downlink signals required for this transmission mode. The network device can configure corresponding sensing signals for the sensing nodes (network devices and / or terminal devices) based on the uplink and downlink signals required for the above transmission mode, and send the sensing signals and receive the echo signals through the sensing nodes, and analyze and process the sensing signals to obtain sensing data.

[0053] Figure 2The figure shows a schematic diagram of the network architecture of a sensing system. In this schematic diagram, the network element functional entities in the sensing system include: Unified Data Management (UDM), Network Data Analytics Function (NWDAF), Location Management Function (LMF), Policy Control Function (PCF), Access and Mobility Management Function (AMF), Sensing Function (SF)-C, SF-U, Network Exposure Function (NEF), Application Function (AF), User Equipment (UE), Radio Access Network ((R)AN), User Plane Function (UPF), Non-3rd Generation Partnership Project Access (N3GPP access), and 3rd Generation Partnership Project-Access Gateway Function (N3-AGF). Among them, the specific functions of the above network element functional entities are as follows: UDM is responsible for managing the subscription data of users; NWDAF is responsible for providing network analysis services; LMF is responsible for performing location calculations on terminal devices; PCF is responsible for user policy control, including session policies, mobility policies, etc.; AMF is responsible for user access and mobility management; SF is responsible for providing sensing services, including the selection of sensing nodes, the configuration and coordination of sensing resources, and the processing of sensing data, etc.; NEF is responsible for opening the capabilities of the 5th generation mobile communication technology (5G) network to external systems; AF is responsible for communicating with the core network to provide services for users; UPF is responsible for user plane processing; N3GPP access is responsible for connecting to the Evolved Packet Core (EPC) in various ways according to the operator's business model and architecture preferences; N3-AGF is responsible for connecting ordinary telephone users to the softswitch network.

[0054] The connection relationships of the above network element functional entities are as follows:

[0055] NI interface: The N1 interface between the UE and the AMF.

[0056] Uu interface: The Uu interface between the UE and the (R)AN.

[0057] N2 interface: The N2 interface between the (R)AN and the AMF.

[0058] N3 interface: The N3 interface between the (R)AN and the UPF.

[0059] N5 interface: The N5 interface between the NEF and the PCF.

[0060] N8 interface: The N8 interface between the UDM and the AMF.

[0061] N33 interface: The N33 interface between the NEF and the AF.

[0062] The above briefly introduces the network architecture of the sensing system in this application.

[0063] In the network device sensing mode, the first network device may send multiple sensing signals. After being scattered by the environment or the sensing target, the above multiple scattered echo signals are received by the first network device and / or the second network device. The first network device and / or the second network device may analyze the above echo signals to obtain sensing data.

[0064] However, in the case where the above sensing target moves, the distance between the sensing target and the sensing nodes (for example, the first network device and the second network device) may be large, resulting in the sensing nodes being unable to monitor and track the sensing target, and then the sensing target cannot be sensed, making it difficult to achieve continuous sensing of the sensing target.

[0065] In view of this, the embodiment of this application provides a method for determining a sensing device. The first network device sends first indication information to the second network device in at least one third network device, so that the second network device senses the sensing target. In this way, when the first network device is unable to sense the sensing target, or the sensing effect of the first network device sensing the sensing target is poor, the sensing device for sensing the sensing target can be switched to the second network device, avoiding the problem that the sensing target cannot be normally sensed. Since the second network device is the network device that senses the sensing target after the switching of the sensing device for the sensing target, the second network device can continue to sense the sensing target to achieve continuous sensing of the sensing target.

[0066] The technical solution provided by the embodiments of the present application can be applied to various communication systems. For example, it can be applied to a New Radio (NR) communication system adopting 5G, a future evolved system, or a multi-communication convergence system, etc.

[0070] Wherein, the first network device 301 is the network device that senses the sensing target before the switching of the sensing device of the sensing target. The third network device is an adjacent network device of the first network device 301. The second network device 302 is the network device that senses the sensing target after the switching of the sensing device of the sensing target. The first indication information is used to instruct the second network device 302 to sense the sensing target.

[0071] In one example, the first network device 301 may be a base station or a base station controller for wireless communication, etc. In the embodiments of the present invention, the first network device 301 may be a base transceiver station (BTS) in a global system for mobile communication (GSM), a code division multiple access (CDMA) system, a node B (NB) in a wideband code division multiple access (WCDMA) system, an evolved Node B (eNB) in a Long Term Evolution (LTE) system, an eNB in an internet of things (IoT) or narrow band-internet of things (NB-IoT) system, a base station in a future 5G mobile communication network or a future evolved public land mobile network (PLMN).

Among them, the sensing network element may be one of the core network elements, such as one of the 5G core network elements, or the sensing network element may not be a core network element, such as an access network device or an external application server.

[0076] In another example, the above-mentioned sensing network element may be an SF network element. Among them, the SF network element is used to manage the sensing operations of the first network device 301. For example, it receives information about requested resources from the second network device 302, participates in the negotiation process of collaborative sensing between the first network device 301 and the second network device 302, and sends down configuration information related to sensing to the first network device 301 and the second network device 302.

[0094]

[0095] S501. The first network device sends first indication information to a second network device among at least one third network device. Correspondingly, the second network device receives the first indication information from the first network device.

[0095] Among them, the first network device is the network device that senses the target before the sensing device of the target is switched. The third network device is an adjacent network device of the first network device. The second network device is the network device that senses the target after the sensing device of the target is switched. The first indication information is used to instruct the second network device to sense the target.

[0096] It can be understood that before the first network device sends the first indication information to the second network device, the first network device can determine the second network device from at least one third network device, so as to facilitate the negotiation between the first network device and the second network device, enabling the second network device to sense the target.

[0097] In a possible embodiment, the implementation process for the first network device to determine the second network device from at least one third network device can be as follows: The first network device sends second indication information to each third network device among at least one third network device and receives third indication information from each third network device. The first network device determines the third network device whose sensing metrics meet the sensing request among at least one third network device as the second network device. Among them, the second indication information is used to request the sensing metrics for the third network device to sense the target. The third indication information is used to indicate the sensing metrics for the third network device to sense the target.

[0098] It can be understood that the first network device sends the second indication information to each third network device among at least one third network device, enabling each of the above-mentioned third network devices to send their respective sensing metrics for sensing the target to the first network device. Correspondingly, each third network device receives the second indication information from the first network device and sends the third indication information to the first network device, enabling the first network device to determine the sensing metrics for each third network device to sense the target, and then to determine the second network device from at least one third network device.

[0099] In a possible implementation manner, in combination with the above embodiments, the implementation process of the above S501 may be as follows: The first network device may determine at least one neighboring network device of the first network device according to network planning, and obtain the location information and sensing metrics of each neighboring network device among the at least one neighboring network device. The first network device determines the predicted moving position of the sensing target, and determines the distances between the predicted moving position of the sensing target and each neighboring network device. The first network device determines the neighboring network devices whose distances from the predicted moving position of the sensing target are less than or equal to a first preset threshold as the third network devices, and obtains the sensing metrics of the third network devices for sensing the sensing target. When the sensing metrics of the third network devices meet the sensing request, the first network device determines the third network device as the second network device. The first network device sends a first indication message to the second network device. Correspondingly, the second network device receives the first indication message from the first network device.

[0100] It can be understood that when the distance between the third network device and the predicted moving position of the sensing target is less than or equal to the first preset threshold, the first network device may determine that the coverage range of the third network device may include the predicted moving position of the sensing target. That is to say, the third network device may be able to sense the target. Therefore, the first network device may obtain the sensing metrics of the third network device for sensing the sensing target, and then determine whether the third network device is the second network device.

[0101] It should be noted that when the distance between the third network device and the predicted moving position of the sensing target is greater than the first preset threshold, the first network device determines that the coverage range of the third network device may not include the predicted moving position of the sensing target. In this case, the first network device may not obtain the sensing metrics of the third network device for sensing the sensing target, and determine that the third network device cannot sense the sensing target, thereby being able to save transmission resources.

[0102] It should be understood that since the network planning may include information of multiple network devices (such as IDs and location information), the first network device may, according to the network planning, not only determine at least one neighboring network device of the first network device and the information of each neighboring network device among the at least one neighboring network device, but also obtain other network devices (such as network devices not adjacent to the first network device) and the information of other network devices. Therefore, the first network device may also determine the second network device from other network devices.

[0103] As an example, the first network device may set a first preset threshold according to the coverage range or experience of the network device. For example, the first network device sets the first preset threshold to 55 meters. The above is only an exemplary description of the first preset threshold, and the first preset threshold may also be other values (for example, 200 meters), and the present application does not impose any restrictions on this.

[0104] In an example, the network device sends the location information of the network device to the first network device. Correspondingly, the first network device receives the location information sent by the above network device.

[0105] In another example, the first network device may also query the location information of each of the above network devices based on network planning.

[0106] The content of the above perception request message is introduced in detail below.

[0107] In a possible embodiment, the perception request message includes perception index parameters; the perception index parameters include at least one of the following: moving speed, moving direction, moving distance, or QoS parameters; the QoS parameters include at least one of the following: positioning accuracy, accuracy and / or resolution information of moving speed, accuracy and / or resolution information of moving direction, accuracy and / or resolution information of moving distance, or perception delay. The above is only an exemplary description of the perception request message, and the perception request message may also include other perception request messages, and the present application does not impose any restrictions on this.

[0108] It should be noted that since accuracy refers to the difference between the sensor measurement value and the true value, the accuracy in the above QoS parameters can be used to characterize the measurement error in the process of the network device perceiving the perception target. Since the resolution refers to the minimum value that the sensor can read, that is, how much the measured value changes to cause the sensor to respond, therefore, the resolution information in the above QoS parameters can also be used to characterize the minimum value of the perception index parameters that can be perceived in the process of the network device perceiving the perception target.

[0109] It can be understood that the first network device uses the perception index parameters as the perception request, which can ensure that the network device whose perception index meets the perception request can perceive the perception target, and can meet the perception requirements in the perception scenario, and thus can obtain the perception information of the perception target that meets the perception request.

[0110] In a possible implementation manner, the first network device may determine whether the perception index of the third network device perceiving the perception target meets the perception request, and determine the third network device whose perception index meets the perception request as the second network device. The first network device determines that the third network device whose perception index does not meet the perception request is not the second network device.

[0111] The following details the implementation process for the first network device to determine whether the perception metrics of the third network device for perceiving the perception target meet the perception request.

[0112] In a possible implementation, the implementation process for the first network device to determine whether the perception metrics of the third network device for perceiving the perception target meet the perception request can be as follows: The first network device can obtain the perception metric parameters required in the perception scenario (for example, the resolution information of the moving speed, the resolution information of the moving direction, the resolution information of the moving distance, and the QoS accuracy), as well as the resolution information of the moving speed that the third network device can perceive, the resolution information of the moving direction, the resolution information of the moving distance, and the QoS accuracy. And when the resolution information of the moving speed, the resolution information of the moving direction, the resolution information of the moving distance, and the QoS accuracy that the third network device can perceive all meet the perception accuracy required in the above perception scenario, it is determined that the perception metrics of the third network device for perceiving the perception target meet the perception request.

[0113] In another possible implementation, the implementation process for the first network device to determine whether the perception metrics of the third network device for perceiving the perception target meet the perception request can also be as follows: The first network device can obtain the parameters that the third network device can support for perception, and the parameters that need to be perceived in the perception scenario (for example, the moving speed and the moving direction). And when the parameters that can be supported for perception include the parameters that need to be perceived in the above perception scenario, the perception accuracy of the third network device for perceiving the parameters that need to be perceived in the perception scenario is determined. The first network device obtains the perception accuracy required in the perception scenario, and when the perception accuracy of the third network device meets the perception accuracy required in the above perception scenario, it is determined that the perception metrics of the third network device for perceiving the perception target meet the perception request.

[0114] In another possible implementation, the implementation process for the first network device to determine whether the perception metrics of the third network device for perceiving the perception target meet the perception request can also be as follows: The first network device can obtain the service types that the third network device can support, and the service types that need to be perceived in the perception scenario. And when the service types that can be supported are the same as the service types that need to be perceived in the perception scenario, the parameters that the third network device can support for perception, the perception accuracy of the third network device for perceiving the parameters that can be supported for perception, the parameters that need to be perceived in the perception scenario, and the perception accuracy required in the perception scenario are obtained. When the parameters that can be supported for perception include the parameters that need to be perceived in the perception scenario, and the perception accuracy meets the perception accuracy required in the perception scenario, the first network device determines that the perception metrics of the third network device for perceiving the perception target meet the perception request.

[0115] In another possible implementation, the above is only an exemplary description of the implementation process for the first network device to determine whether the sensing metrics of the third network device for sensing the sensing target meet the sensing request. The implementation process for the first network device to determine whether the sensing metrics of the third network device for sensing the sensing target meet the sensing request may also be other implementation processes, and this application does not impose any restrictions on this.

[0116] It should be noted that when there are multiple third network devices whose sensing metrics meet the sensing request, the first network device may compare the sensing metrics of each of the multiple third network devices and determine the third network device with a relatively high similarity between the sensing metrics and the actually required sensing metrics as the second network device.

[0117] As a possible implementation, the implementation process for the first network device to determine the second network device from multiple third network devices that meet the sensing request may be: The first network device may obtain the sensing accuracy of each of the multiple third network devices that meet the sensing request, compare the sensing accuracy, and determine the third network device with the sensing accuracy closest to the accuracy in the sensing request as the second network device.

[0118] As another possible implementation, the implementation process for the first network device to determine the second network device from multiple third network devices that meet the sensing request may also be: The first network device may obtain the sensing parameters supported by each of the multiple third network devices that meet the sensing request, compare the sensing parameters supported by each third network device, and determine the third network device with the highest similarity between the supported sensing parameters and the sensing metric parameters in the sensing request as the second network device.

[0119] As another possible implementation, the implementation process for the first network device to determine the second network device from multiple third network devices that meet the sensing request may also be: The first network device may obtain the distance between each of the multiple third network devices that meet the sensing request and the predicted moving position of the sensing target, compare the distances between each of the third network devices and the predicted moving position of the sensing target, and determine the third network device with the shortest distance as the second network device.

[0120] As another possible implementation, the implementation process for the first network device to determine the second network device from multiple third network devices that meet the sensing request may also be: The first network device may determine the power consumption of each of the multiple third network devices that meet the sensing request during the process of sensing the sensing target within a preset time period, and determine the third network device with the lowest power consumption as the second network device.

[0121] It can be understood that the first network device determines the third network device with the lowest power consumption among the third network devices that meet the sensing request as the second network device, which can save the power consumption of the second network device for sensing the sensing target, and thus save the power cost.

[0122] As another possible implementation, the implementation process of the first network device determining the second network device from multiple third network devices that meet the sensing request can also be: the first network device can determine the distance between each third network device and the first network device among the multiple third network devices that meet the sensing request, and compare the distances between each of the third network devices and the first network device, and determine the third network device with the closest distance as the second network device.

[0123] It can be understood that the first network device determines the third network device with the closest distance to the first network device among the third network devices that meet the sensing request as the second network device, which can reduce the path loss in the process of information interaction between the first network device and the second network device.

[0124] It should be noted that for the implementation process of the first network device determining the second network device from multiple third network devices whose sensing indicators meet the sensing request described above, they can be combined arbitrarily, and this application does not impose any restrictions on this.

[0125] In a possible implementation, when the sensing indicators of the third network device for sensing the sensing target do not meet the sensing request, the first network device can compare the sensing indicators of the third network device whose sensing indicators do not meet the sensing request, and determine the third network device with relatively better sensing indicators as the second network device.

[0126] As a possible implementation, the implementation process of the first network device comparing the sensing indicators of the third network device whose sensing indicators do not meet the sensing request and determining the second network device can be understood with reference to the description at the corresponding position above (that is, the implementation process of the first network device determining the second network device from multiple third network devices whose sensing indicators meet the sensing request), and will not be elaborated here.

[0127] It can be understood that the third network device is a network device capable of perceiving the target to be perceived, which can ensure that the distance between the third network device and the predicted moving position of the target to be perceived is relatively close, so that the third network device can perceive the target to be perceived. The second network device is a network device among the third network devices whose perception metrics meet the perception request, which can ensure that the second network device can not only perceive the target to be perceived, but also meet the perception request during the process of perceiving the target to be perceived. Furthermore, the second network device can realize the perception of the target to be perceived, so as to realize the continuous perception of the target to be perceived. In a possible embodiment, the process for the first network device to determine the third network device may be: when the distance between the predicted moving position of the target to be perceived and the network device is less than or equal to the first preset threshold, the first network device determines the network device as the third network device.

[0128] In some possible implementation manners, the process for the first network device to determine the third network device may be: the first network device can determine the distance between the network device and the target to be perceived based on the predicted moving position of the target to be perceived, and then determine whether the target to be perceived is within the coverage range of the network device. When the target to be perceived is within the coverage range of the network device, the first network device determines the network device as the third network device.

[0129] In a possible implementation manner, the process for the first network device to determine the third network device may be: the first network device can determine the predicted moving position of the target to be perceived and the location information of the network device, and determine the distance between the target to be perceived and the network device based on the distance formula. When the distance between the target to be perceived and the network device is less than or equal to the first preset threshold, the first network device determines the network device as the third network device.

[0130] Exemplarily, the predicted moving position of the target to be perceived and the location information of the network device may include longitude information, latitude information, and altitude information. The above is only an exemplary description of the predicted moving position of the target to be perceived and the location information of the network device. The predicted moving position of the target to be perceived and the location information of the network device may also include other information, and this application does not make any restrictions thereon.

[0131] In another possible implementation, the process for the first network device to determine the third network device may also be as follows: The first network device determines the predicted moving position of the sensing target and the coverage range of the network device, and based on the predicted moving position of the sensing target and the coverage range of the network device, determines whether the predicted moving position of the sensing target is within the coverage range of the network device. When the predicted moving position of the sensing target is within the coverage range of the network device, the first network device determines that this network device is the third network device. Correspondingly, when the predicted moving position of the sensing target is not within the coverage range of the network device, the first network device determines that this network device is not the third network device.

[0132] It should be noted that when the predicted moving position of the sensing target is within the coverage range of the network device, the first network device can determine that the distance between the sensing target and the network device is less than or equal to the first preset threshold. Therefore, the first network device determines that this network device can sense the sensing target, and then can select a network device that senses the sensing target from them.

[0133] It can be understood that when the distance between the predicted moving position of the sensing target and the network device is greater than the first preset threshold, the distance between the sensing target and the network device is relatively large. Furthermore, the effect of the network device sensing the sensing target may be poor, or the network device cannot sense the sensing target. Therefore, the first network device determines that this network device is not the third network device.

[0134] In a possible embodiment, the process for the first network device to determine the predicted moving position of the sensing target may be as follows: The first network device monitors the sensing target to obtain the sensing information of the sensing target, and based on the sensing information, determines the predicted moving position of the sensing target. The sensing information includes the initial position, moving speed, and moving direction.

[0135] As an example, the above initial position may be the initial position of the sensing target obtained during the process of the first network device sensing the sensing target.

[0136] In a possible implementation, the implementation process for the first network device to determine the predicted movement position of the sensed target may be as follows: The first network device monitors the sensed target to determine the initial position, movement speed, and possible movement direction of the sensed target at the current moment. The first network device determines the possible distance that the sensed target may move in the above possible movement direction within a preset time period based on the movement speed of the sensed target at the current moment. The first network device combines the initial position of the sensed target and the possible distance that the sensed target may move in the above possible movement direction within the target time period to determine at least one predicted position where the sensed target may appear at the preset moment. The first network device determines each of the at least one predicted positions as the predicted movement position of the sensed target.

[0137] In another possible implementation, the implementation process for the first network device to determine the predicted movement position of the sensed target may also be as follows: The first network device determines the possible movement direction of the sensed target within a preset time period and the initial position of the sensed target at the current moment, and determines the predicted movement trajectory of the sensed target starting from the position of the sensed target at the current moment based on the possible movement direction of the sensed target within the preset time period and the initial position of the sensed target at the current moment. The first network device determines the distance that the sensed target moves on the above predicted movement trajectory within the preset time period based on the movement speed of the sensed target, and determines the position of the sensed target on the predicted movement trajectory at the preset moment. The first network device determines the position of the sensed target on the predicted movement trajectory at the preset moment as the predicted movement position of the sensed target.

[0138] As an example, the above preset moment may be a moment after the current moment, and the time period between the current moment and the preset moment may be the preset time period. The above preset time period may be 10 minutes. The above is only an exemplary description of the preset time period, and the above preset time period may also be other time periods (for example, 20 minutes), and this application does not make any restrictions on this.

[0139] It should be noted that the above is only an exemplary description of the implementation process for the first network device to determine the predicted movement position of the sensed target. The implementation process for the first network device to determine the predicted movement position of the sensed target may also include other implementation processes, and this application does not make any restrictions on this.

[0140] The following describes the first indication information in the embodiments of this application.

[0141] An example is that the above first indication information may be the Sensing Coordination Confirm information sent by the first network device to the second network device. As shown in Table 1 below, Table 1 describes at least one of the information element / group name, Presence, Range, or IE type and reference. The above Sensing Coordination Confirm information may include: Message Type, Source Cell Global ID, Target Cell Global ID, Velocity, Angle, and Distance.

[0142] Table 1

[0143]

[0144]

[0145] It should be noted that M stands for mandatory and can be used to indicate a mandatory item. Velocity, Angle, and Distance can be used to indicate the parameters that need to be sensed during the process of the second network device sensing the sensing target. Source Cell Global ID can be used to indicate the ID of the first network device. Target Cell Global ID can be used to indicate the ID of the second network device.

[0146] In one example, the above first indication information may further include the sensing index parameters required during the process of sensing the sensing target (for example, velocity, angle, or distance). The above is only an exemplary description of the first indication information, and the first indication information may further include other information. The present application places no restrictions on this.

[0147] In a possible embodiment, the first indication information is further used to indicate the configuration resources required by the second network device when requesting the sensing network element to sense the sensing target.

[0148] In a possible implementation, after the second network device receives the first indication information from the first network device, the second network device may determine the predicted time for the sensed target to reach the coverage range of the second network device as the target time based on the position, moving speed, and moving direction of the sensed target at the current moment carried in the first indication information. The second network device may request the sensing network element to send the configuration resources required for sensing the sensed target to the second network device at the above target time.

[0149] In a possible embodiment, the second network device sends fourth indication information to the sensing network element. Correspondingly, the sensing network element receives the fourth indication information from the second network device and sends the configuration resources to the second network device. The second network device receives the configuration resources from the sensing network element. Wherein, the fourth indication information is used to request the sensing network element to send the configuration resources required for sensing the sensed target to the second network device at the target time.

[0150] In a possible implementation, the process for the second network device to determine the target time may be: The second network device determines the distance between the sensed target and the second network device in the moving direction at the current moment, and determines the ratio of the above distance to the moving speed as the target time period. The second network device determines the target time based on the current time and the target time period. For example, the second network device determines that the time period between the target time and the current time is the target time period.

[0151] It can be understood that the second network device requests the sensing network element to send the configuration resources required for sensing the sensed target to the second network device at the target time, which can not only avoid the problem of resource idleness caused by the sensing network element sending the configuration resources too early, but also avoid the problem that the sensing network element sends the configuration resources too late, resulting in the second network device not having the resources for sensing the sensed target, and further avoid the problem that the second network device cannot sense the sensed target.

[0152] In a possible implementation, the second network device may also determine the time to request resources from the sensing network element based on the above predicted time. The second network device sends the fourth indication information to the sensing network element at the time to request resources from the sensing network element, so that the sensing network element configures resources for the second network device.

[0153] An example of the process for the second network device to determine the time to request resources from the sensing network element based on the predicted time may be: The second network device may determine the information transmission time during the process of the second network device requesting resources from the sensing network element according to experience, and determine the difference between the predicted time and the information transmission time as the time to request resources from the sensing network element.

[0154] Exemplarily, the second network device may determine the duration from sending the fourth indication information to the sensing network element until receiving the configuration resources from the sensing network element as the above information transmission time. The above is only an exemplary description of the information transmission time, and the above information transmission time may also be other times, and this application does not make any restrictions on this.

[0155] In one example, the fourth indication information sent by the second network device to the sensing network element may include MessageType, Source Cell Global ID, SF UE identity document (ID), sensing parameters, and sensing node type. Among them, the sensing parameters may include one or more of Velocity, Angle, and Distance. The sensing node type may include a receive node (Rx) and a transport node (Tx). The above is only one example of the fourth indication information, and the above fourth indication information may also include other information (for example, the target time), and this application does not make any restrictions on this.

[0156] In a possible implementation manner, after receiving the fourth indication information, the sensing network element may send the configuration resources required by the second network device for sensing the sensing target to the second network device.

[0157] In one example, the configuration resources required by the second network device for sensing the sensing target may include Message Type, Source Cell Global ID, SF UE ID, and the type of the selected sensing reference signal. Among them, the type of the selected sensing reference signal may be a positioning reference signal (PRS) or a sounding reference signal (SRS). The above is only one example of the configuration resources, and the above configuration resources may also include other information, and this application does not make any restrictions on this.

[0158] It should be noted that when the second network device is a receive node, the type of the selected sensing reference signal may be PRS. When the second network device is a transport node, the type of the selected sensing reference signal may be SRS.

[0159] It can be understood that the second network device requests the resources required for sensing the sensing target from the sensing network element (i.e., the second network device sends the fourth indication information to the sensing network element), and receives the configuration resources required for sensing the sensing target from the sensing network element. In this way, the second network device can utilize the resources required for sensing the sensing target to implement the sensing function and the sensing of the sensing target, ensuring continuous sensing of the sensing target.

[0160] In a possible implementation manner, after the second network device receives the above-mentioned configuration resources required for sensing the sensing target, the implementation process of the second network device sensing the sensing target can be as follows: The second network device sends a sensing signal, and after being scattered by the environment or the sensing target, the second network device, or the first network device and the second network device receive the echo signal corresponding to the above-mentioned sensing signal.

[0161] It can be understood that the first indication information sent by the first network device to the second network device is also used to instruct the second network device to request the configuration resources required for sensing the sensing target from the sensing network element, so that the second network device requests the resources required for sensing the sensing target from the sensing network element, and further enables the second network device to obtain the resources required for sensing the sensing target to implement the sensing of the sensing target.

[0162] The following describes the second indication information in the embodiments of the present application.

[0163] An example is that the above-mentioned second indication information can be a Sensing Coordination Request sent by the first network device to the third network device. As shown in Table 2 below, Table 2 describes at least one of the IE / group name, Presence, Range, or IE type and reference of the Sensing Coordination Request. The above-mentioned Sensing Coordination Request may include: Message Type, Source Cell Global ID, Target Cell Global ID, Relative Geodetic Location, Velocity, Angle, and quality of service (QoS) parameters.

[0164] In combination with the above examples, Relative Geodetic Location may include at least one of the following: Height Units, Delta Latitude, Delta Longitude, or Delta Height. The above is only an exemplary description of Relative Geodetic Location, and Relative Geodetic Location may also include other localizations, and this application does not impose any restrictions thereon.

[0165] The enumerated type (ENUMERATED) of Height Units may include at least one of the following: millimeter (mm), centimeter (cm), or meter (m). The above is only an exemplary description of the ENUMERATED of Height Units, and the ENUMERATED of Height Units may also include other types, and this application does not impose any restrictions thereon.

[0166] The values of Delta Latitude, Delta Longitude, and Delta Height may be integers (INTEGER) between -1024 and 1023. The above is only an exemplary description of the values of Delta Latitude, Delta Longitude, and Delta Height, and the values of Delta Latitude, Delta Longitude, and Delta Height may also be other values, and this application does not impose any restrictions thereon.

[0167] QoS parameters may include at least one of the following: Accuracy of positioning estimate, Accuracy of velocity estimate, Sensing resolution, Range resolution, Velocity resolution, or Max sensing service latency. The above is only an exemplary description of QoS parameters, and QoS parameters may also include others, and this application does not impose any restrictions thereon.

[0168] Table 2

[0169]

[0170]

[0171] It should be noted that Angle can be used to represent direction. M is mandatory and can be used to represent mandatory.

[0172] As a possible implementation, the second indication information sent by the first network device to the third network device may further include the position of the sensed target at the current moment, the moving speed of the sensed target at the current moment, the moving direction of the sensed target at the current moment, and the sensing parameters that can be satisfied currently.

[0173] It can be understood that in the case where the third network device can act as the second network device to sense the sensed target, the third network device can determine the predicted movement trajectory of the sensed target based on the position of the sensed target at the current moment, the moving speed of the sensed target at the current moment, and the moving direction of the sensed target at the current moment, so that the third network device can determine the sensing index for sensing the sensed target based on the predicted movement trajectory and the big data analysis model subsequently.

[0174] The following describes the third indication information in the embodiments of the present application.

[0175] In a possible implementation, the third network device determines the sensing index for sensing the sensed target by itself and sends the third indication information to the first network device. Correspondingly, the first network device receives the third indication information from the third network device.

[0176] An example is that the third indication information may be a Sensing Coordination Response sent by a third network device to a first network device. As shown in Table 3 below, Table 3 describes at least one of the IE / group name, Presence, Range, and IE type and reference of the Sensing Coordination Request. The above Sensing Coordination Response may include: Message Type, Source Cell Global ID, Target Cell Global ID, Velocity, Angle, Distance, and QoS parameters. Among them, the QoS parameters may include at least one of the following: Accuracy of velocity estimate, Sensing resolution, Range resolution, Velocity resolution, or Max sensing service latency. The above is only an exemplary description of the QoS parameters, and the above QoS parameters may also include others, and the present application does not impose any restrictions on this.

[0178]

[0179] In a possible implementation, the first network device may receive the third indication information from the third network device and determine whether the sensing metrics for the sensing target sensed by the third network device meet the sensing request.

[0180] In the sensing device determination method provided by the embodiments of the present application, the first network device sends first indication information to a second network device among at least one third network device, so that the second network device senses the sensing target. In this way, when the first network device is unable to sense the sensing target or the sensing effect of the first network device on the sensing target is poor, the sensing device for sensing the sensing target can be switched to the second network device to avoid the problem that the sensing target cannot be normally sensed. Since the second network device is the network device that senses the sensing target after the sensing device for the sensing target is switched, the second network device can continue to sense the sensing target to achieve continuous sensing of the sensing target.

[0181] In a possible embodiment, before the first network device sends the first indication information to the second network device, the second network device may determine the perception metrics for perceiving the perception target, and send the perception metrics for perceiving the perception target by the second network device to the first network device, so that the first network device can determine whether the second network device perceives the perception target based on the perception metrics for perceiving the perception target by the second network device. On the basis of the method embodiment shown in Figure 5 This embodiment provides a possible implementation manner. Combining Figure 5 , as Figure 6 shown, the implementation process of the second network device determining the perception metrics for perceiving the perception target can be determined by the following S601 to S602.

[0182] S601. The second network device obtains the predicted trajectory information of the perception target and the big data analysis model.

[0183] Among them, the big data analysis model is used to determine the perception metrics for perceiving the perception target.

[0184] In a possible implementation manner, the implementation process of the above S601 may be: the second network device obtains the position, moving speed, and moving direction of the perception target at the current moment, and determines the predicted trajectory information of the perception target based on the position, moving speed, and moving direction of the perception target at the current moment.

[0185] As an example, the above predicted trajectory information may include a predicted movement trajectory and a predicted movement position. The above is only an exemplary description of the predicted trajectory information, and the above predicted trajectory information may also include other information, and this application does not make any restrictions on this.

[0186] S602. The second network device inputs the predicted trajectory information into the big data analysis model to obtain the perception metrics for the second network device to perceive the perception target.

[0187] As a possible implementation manner, the implementation process of the above S602 may be: the second network device inputs the predicted trajectory information of the perception target into the big data analysis model to obtain the perception metric parameters and perception accuracy that the second network device can detect in the above predicted movement trajectory.

[0188] In a possible embodiment, the second network device perceives the perception target, determines the actual trajectory information of the perception target and the actual perception metrics of the second network device, and updates the big data analysis model based on the actual trajectory information and the actual perception metrics.

[0189] As a possible implementation, the first network device determines that the second network device senses a sensing target, and the actual movement trajectory of the sensing target can be obtained. The second network device may compare the actual movement trajectory with the predicted movement trajectory to obtain the sensing index parameter and sensing accuracy of the second network device on the actual movement trajectory of the sensing target. The second network device uses the actual movement trajectory of the sensing target, the sensing index parameter, and the sensing accuracy on the actual movement trajectory as updated sample data to update the big data analysis model, and obtains an updated big data analysis model.

[0190] It can be understood that the second network device updates the big data analysis model based on the actual movement trajectory of the sensing target, the sensing index parameter, and the sensing accuracy on the corresponding actual movement trajectory. Using the updated sample data in this way can improve the accuracy and performance of the big data analysis model, and further help the big data analysis model better understand and capture patterns and changes in the input data (e.g., the predicted movement trajectory of the sensing target). As a result, the data obtained by the second network device using the updated big data analysis model (e.g., the sensing index parameter and sensing accuracy that the second network device can detect in the predicted movement trajectory of the sensing target) is more accurate.

[0191] It should be noted that the implementation process of determining the sensing index of the third network device sensing the sensing target by the third network device can also be understood by referring to the implementation process of determining the sensing index of the second network device sensing the sensing target by the second network device (S601 to S602).

[0192] In the sensing device determination method provided in the embodiments of the present application, the big data analysis model, based on artificial intelligence technology, establishes a strong association between the movement trajectory of the sensing target and the sensing index (i.e., the detectable sensing index parameter) of the network device sensing the sensing target in the above movement trajectory. Therefore, when the second network device inputs the predicted movement trajectory of the sensing target into the big data analysis model, it can obtain a relatively accurate sensing index of the second network device sensing the sensing target, and further enable the first network device to determine the network device for sensing the sensing target.
