[0161] Before describing the embodiments of the present application, the technical terms involved in the embodiments of the present application are described.

[0162] Wireless sensing technology: Existing wireless signals in the environment (such as sound, light, and radio frequency signals) can, in addition to fulfilling their primary functions (illumination and communication), also be used to "additionally" perceive the environment. For example, radio waves generated by a transmitter undergo physical phenomena such as direct transmission, reflection, and scattering during propagation, resulting in multiple propagation paths. The resulting multipath signal at the receiver carries information about the signal propagation space. Wireless sensing technology (also known as sensorless scene perception technology) analyzes changes in wireless signals during propagation to determine the characteristics of the signal propagation space (channel) and achieve scene perception. During wireless communication, electromagnetic waves carry environmental information while propagating through space. For example, if a mobile phone receives a weak wireless fidelity (Wi-Fi) signal, it may be because the phone is far away from the wireless router. A sudden drop in Wi-Fi signal strength may indicate that the phone has entered a specific enclosed space, such as an elevator. In this example, the received signal strength indicator (RSSI) is used as a feature to infer the phone's location and surroundings. The selection of signal features has a key impact on perception accuracy, reliability, model generalization ability, etc.

[0163] Radar sensing is a common wireless sensing technology that analyzes the characteristics of received echo signals from target objects to extract and detect their location, shape, motion characteristics, and trajectory. It can also further infer characteristics of the target object and its surroundings. Its function is similar to that of the human eyes and ears. Compared to other sensors, radar sensing offers many unique advantages. For example, compared to visual sensors, radar is unaffected by light levels and can penetrate obstructions, thus better protecting personal privacy. Compared to ultrasonic technology, radar has a longer range and is harmless to humans and animals. Radar sensing supports a wide range of application scenarios. For example, millimeter-wave radar is already widely used in assisted driving, detecting pedestrians and preceding vehicles for collision avoidance and warning. Radar sensing also has many potential applications in areas such as homes, smart buildings, autonomous driving, and wearable devices. With the continuous development of new, low-power, and compact radar sensors, radar technology has found widespread application in many smart devices and electronic products. As shown in Table 1 below, radar can be used to perceive the surrounding environment / objects based on the attenuation and reflection during signal transmission.

[0164] Table 1

[0165] The advantage of radar sensing technology lies in its ability to detect motion. It uses the Doppler effect on the target's echo signal to observe and interpret the target's motion state, such as direction and speed. Using multi-channel sensors, it can also observe the target's motion from different perspectives. By capturing the target's motion state from different perspectives and analyzing it with a combination of instantaneous and historical information, it can resolve complex motion.

[0166] The following four methods are used to briefly explain wireless sensing technology, including detecting the presence of a target object and its direction of movement:

[0167] Method 1: The signal transmitter sends a sensing signal, and the signal receiver detects the sensing signal.

[0168] Method 2: Determine whether a target object passes through the detection area based on the change in wireless received signal strength. This method is mainly used for line of sight (LOS) scene detection.

[0169] Method 3: Utilize the amplitude and phase information in the channel state information, after filtering and other processing, to replace the wireless received signal strength detection, thereby improving the detection accuracy of the target object, especially the detection in non-line of sight (NLOS) scenarios.

[0170] Method 4: Based on the channel state information analysis of multiple signal receivers, the movement direction information of the target object in the monitoring area is obtained.

[0171] With the development of fifth-generation (5G) mobile communication networks, the demand for new perception-based network capabilities is gradually emerging. For example, in certain scenarios such as smart cities and smart transportation, the need to obtain information such as the relative position and angle between objects, as well as their distance, speed, and shape, is gradually emerging. To meet these business needs, 5G networks should be further enhanced to include the ability to assist wireless networks in perception. Future 5G networks may deploy integrated radar and communication base stations to enhance base station perception capabilities. The radar's precise perception capabilities enable precise communication and improve communication efficiency. For example, base station communication and perception resources can be time-division multiplexed or space-division multiplexed to achieve perception of the surrounding environment or objects. Perception functions can be used in security scenarios where cameras are not suitable. For example, in certain industrial parks, it can detect intrusions by flying objects such as drones. In traffic scenarios, roadside stations can perform functions such as traffic flow statistics and vehicle navigation, all of which require roadside base stations to have certain perception capabilities.

[0172] In addition, 5G network terminal devices can also have perception capabilities to achieve perception of the surrounding environment or objects. For example, as shown in Figure 1, the terminal device can send a perception signal and collect echo signals reflected from other target objects in the surrounding environment. This process can be called perception measurement, and this perception measurement mode can also be called self-transmission and self-reception. For another example, as shown in Figure 2, the terminal device can send a perception signal, and other terminal devices can collect echo signals reflected from other target objects in the surrounding environment. This perception measurement mode can also be called terminal device transmission and other terminal devices receiving.

[0173] It is understandable that different perception measurement modes have different requirements for the capabilities of terminal devices. In different application scenarios, different perception measurement modes can be used to perceive and measure the surrounding environment. In addition, the terminal devices in Figures 1 and 2 can also be replaced with perception devices such as base stations.

[0174] Based on the above description of communication perception, when the target object is constantly moving, as shown in Figure 3, the drone may cross the perception areas of multiple base stations during its flight mission. From a business perspective, the unmanned aerial vehicle controller (UAV-C) or unmanned aerial system traffic management (UTM) network element needs to continuously track and perceive the target object through the perception function network element to ensure that the perception service provided by the communication system can meet user needs.

[0175] Therefore, when the target object is constantly moving, how to achieve continuous perception of the target object and ensure the continuity of the perception service becomes a technical problem that needs to be solved urgently.

[0176] The following describes in detail the implementation of the embodiments of the present application in conjunction with the accompanying drawings.

[0177] The perception measurement method provided in the embodiment of the present application can be used in any communication system, which may be a third generation partnership project (3GPP) communication system, for example, a long term evolution (LTE) system, or a 5G mobile communication system, a new radio (NR) communication system, a new radio vehicle to everything (NR V2X) system, and can also be applied to a system of LTE and 5G hybrid networking, or a non-terrestrial network (NTN) system, a device-to-device (D2D) communication system, a machine-to-machine (M2M) communication system, an Internet of Things (IoT), and other next-generation communication systems, such as future communication systems such as 6G, and may also be non-3GPP communication systems without limitation.

[0182] The terminal device in Figure 4 can be a device with wireless transceiver capabilities or a chip or chip system that can be installed in the device, which can allow users to access the network and is used to provide voice and / or data connectivity to users. The terminal device can also be called user equipment (UE), subscriber unit (subscriber unit), terminal (terminal), mobile station (MS), or mobile terminal (MT).

[0183] Exemplarily, the terminal device in FIG4 may be a mobile phone, a tablet computer, or a computer with wireless transceiver function. The terminal device may also be a user station, a mobile station, a remote station, a remote terminal device, a mobile terminal device, a user terminal device, a wireless communication device, a user agent, a user device, a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device, a processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in the Internet of Things, a home appliance, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, a wireless terminal in a smart home, a vehicle with vehicle-to-vehicle (V2V) communication capabilities, an intelligent connected vehicle, a UAV to UAV (UAV to Unmanned aerial vehicles (UAVs, U2Us) with communication capabilities, terminal devices in future networks, or terminal devices in future evolved public land mobile networks (PLMNs), etc. are not restricted.

Specifically, the network device can be a device that supports wired access or a device that supports wireless access.

[0186] In another example, the access network device may also be a device including a centralized unit (CU) node, or a distributed unit (DU) node, or a CU node and a DU node. For example, the access network device can be divided into CU and DU from a logical function perspective, with some protocol layer functions placed in the CU for centralized control, and the remaining part or all of the protocol layer functions distributed in the DU, which is centrally controlled by the CU. Furthermore, the centralized unit CU can also be divided into a control plane (CU-CP) and a user plane (CU-UP). In different systems, CU (including CU-CP or CU-UP) or DU may also have different names. For example, in an open radio access network (O-RAN) system, CU may also be called O-CU (open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, and CU-UP may also be called O-CU-UP.

[0187] The application function network element is primarily responsible for providing certain application layer services to terminal devices. When providing services to terminal devices, the application function network element has requirements for quality of service (QoS) and charging policies, and needs to notify the network of these requirements. At the same time, the application function network element also requires application-related information fed back by the core network.

[0194] The unified database is primarily responsible for storing and retrieving contract data, policy data, and public architecture data. It provides access to relevant data for unified data management network elements, policy control network elements, and network open network elements. The unified database can implement different data access authentication mechanisms for different types of data, such as contract data and policy data, to ensure data access security.

[0216] In combination with the communication system shown in Figure 4, Figure 5 or Figure 6, as shown in Figure 8, a third-party application can send a perception service request to the core network (such as an application function network element), and the core network (such as a perception function network element, a network storage function network element, a mobility management network element, etc.) selects a suitable perception device to perform perception measurement on the target object to achieve service continuity.

[0218] FIG9 is a flow chart of a perception measurement method provided in an embodiment of the present application. As shown in FIG9 , the method may include:

[0219] Step 901: The perception function network element obtains feature information of a target object.

[0220] The characteristic information of the target object may include one or more of the following: the shape of the target object, the size of the target object, and the dimensions of the target object.

[0221] Optionally, the perception function network element may obtain characteristic information of the target object from the application function network element or the mobility management network element.

[0222] The application function network element may send characteristic information of the target object to the perception function network element. Alternatively, the application function network element may send the characteristic information of the target object and the first location of the target object to the open network element. The open network element selects a mobility management network element whose coverage area includes the first location of the target object based on the first location of the target object, and then sends the characteristic information of the target object to the mobility management network element. The mobility management network element then sends the characteristic information of the target object to the perception function network element.

[0223] Optionally, the application function network element may carry the characteristic information of the target object in the third request and send it to the perception function network element, or may send the third request to the perception function network element through the network open network element and the mobility management network element.

[0224] The third request may also be referred to as a perception service request, wherein the third request may be used to request acquisition of a movement trajectory of a target object, or the third request may be used to request perception of the target object.

[0225] Optionally, the third request may further include one or more of the following: the first position of the target object, the start time of the perception measurement, the end time of the perception measurement, and a preset movement trajectory of the target object.

[0226] Optionally, before the perception function network element obtains the characteristic information of the target object, the application function network element may also send a fifth request to the perception function network element to request perception measurement of the first area. The fifth request may include the area information of the first area. Based on the fifth request, the perception function network element may send a sixth request to the perception device corresponding to the first area to request perception measurement. Based on the sixth request, the perception device may perform perception measurement on the first area and send the perception measurement result to the perception function network element. The perception function network element then sends the perception measurement result corresponding to the first area to the application function network element. Based on the perception measurement result of the first area, the application function network element may determine one or more of the following information of the target object that needs to be perceived and measured in the first area: characteristic information of the target object and the first position of the target object. The application function network element may then send the third request to the perception function network element, or send the third request to the perception function network element via the mobility management network element.

[0227] Among them, the perception device in the embodiment of the present application can be a device with perception function, such as an access network device with perception function, or a terminal device with perception function, etc., without limitation.

[0228] The sensing device may report its own device information to the core network. When sensing measurement is required, the network element in the core network may select an appropriate sensing device to perform the sensing measurement based on the device information of each sensing device.

[0229] The device information of the sensing device may include identification information of the sensing device and sensing area information of the sensing device. Optionally, it may also include location information of the sensing device. The location information of the sensing device and the sensing area information of the sensing device may also be collectively referred to as the sensing capability of the sensing device.

[0230] Exemplarily, as an implementation method, the perception device may register its own device information with a network storage function network element (such as an NRF). For example, if the perception device can directly communicate with the network storage function network element, the perception device may register its own device information with the network storage function network element. Alternatively, if the perception device cannot directly communicate with the network storage function network element, the perception device may register its own device information with the network storage function network element through a mobility management network element. Alternatively, as another implementation method, the perception device may also send device information to the perception function network element. For example, if the perception device can directly communicate with the perception function network element, the perception device may send its own device information to the perception function network element. Alternatively, if the perception device cannot directly communicate with the perception function network element, the perception device may send its own device information to the perception function network element through a mobility management network element.

[0231] When it is necessary to perform perception measurement on the above-mentioned first area, the perception function network element may send a fourth request to the network storage function network element to request the discovery of the perception device, and the fourth request may include the area information of the first area. Based on the area information of the first area, the network storage function network element may determine the perception device corresponding to the first area according to the device information of each perception device, and indicate it to the perception function network element through a fourth response. The perception function network element may determine the perception device corresponding to the first area according to the fourth response. Alternatively, the perception function network element may also determine the perception device corresponding to the first area based on the area information of the first area and the device information of each perception device received. Then, the application function network element may determine the above-mentioned target object according to the perception measurement result corresponding to the first area.

[0232] Step 902: The perception function network element sends a first request to a first perception device corresponding to a first position of the target object; correspondingly, the first perception device receives the first request from the perception function network element.

[0233] The first request may be used to request a perception measurement.

[0234] Among them, when the third request includes the first position of the target object, the perception function network element can determine the first perception device based on the first position. Alternatively, when the third request includes a preset movement trajectory of the target object, the perception function network element can determine the first position based on the preset movement trajectory (for example, determining the starting position of the preset movement trajectory as the first position, or determining the position corresponding to the current moment in the preset movement trajectory as the first position), and then determine the first perception device based on the first position. Alternatively, the perception function network element determines that the target object is located at the first position based on the obtained perception measurement results, and determines the first perception device based on the first position. The perception area of ​​the first perception device can cover the first position.

[0235] In one possible design, the perception function network element may send a fourth request to the network storage function network element to request the discovery of a perception device, and the fourth request may include a first location and / or a preset movement trajectory. Based on the first location and / or the preset movement trajectory, the network storage function network element may determine, according to the device information of each perception device, one or more perception devices whose perception areas can cover the first location and / or the preset movement trajectory, and send the identification information of the determined one or more perception devices and the perception area information of each perception device to the perception function network element through a fourth response. The perception function network element selects a perception device from the one or more perception devices as the first perception device based on the first location and the fourth response.

[0236] In another possible design, the perception function directly receives identification information of one or more perception devices and perception area information of each perception device from a mobility management network element; or the perception function sends a request or subscription message to the mobility management network element for obtaining perception device information, and the mobility management network element responds to the request or subscription message by sending the identification information and perception area information of the one or more perception devices to the perception function. The perception function network element selects a perception device from the one or more perception devices as the first perception device based on the first location and the perception area information of the one or more perception devices.

[0237] Optionally, the first request may further include one or more of the following: characteristic information of the target object, the first position, and first indication information. The first indication information is used to instruct to activate the sensing measurement in all sensing areas of the sensing device.

[0238] The perception function network element may carry the characteristic information and / or the first position of the target object in a first request sent to the first perception device, thereby instructing the first perception device to only perceive the target object, thereby reducing power consumption caused by perception. Alternatively, the perception function network element may carry the first indication information in the first request sent to the first perception device, thereby instructing the first perception device to activate perception measurement in all perception areas of the first perception device, thereby improving the accuracy of the perception measurement results.

[0239] Step 903: The first sensing device sends the sensing measurement result to the sensing function network element; correspondingly, the sensing function network element receives the sensing measurement result from the first sensing device.

[0240] The first sensing device may perform a sensing measurement based on the first request sent by the sensing function network element, obtain a sensing measurement result, and transmit the sensing measurement result to the sensing function network element. It is understood that the sensing measurement result may specifically be point cloud data obtained based on the received echo signal, or may be a result of calculation or processing based on the point cloud data. The embodiments of this application do not limit the specific form of the sensing measurement result.

[0241] Optionally, the perception function network element may further send second instruction information to the first perception device, where the second instruction information is used to instruct the first perception device to stop the perception measurement. The first perception device stops the perception measurement according to the second instruction information.

[0242] Exemplarily, the perception function network element may determine, based on the perception measurement result of the first perception device and the perception area information of the first perception device, that when the target object leaves the perception area of ​​the first perception device, send second indication information to the first perception device.

[0243] In another example, the perception function network element can also predict the movement trajectory of the target object based on the perception measurement results of the first perception device. When it is determined according to the prediction results that the target object is about to leave the perception area of ​​the first perception device, the perception function network element can send a second indication information to the first perception device.

[0244] Step 904: The perception function network element determines that the target object moves to the second position based on the characteristic information of the target object and the perception measurement result of the first perception device.

[0245] The second position may be a position in the target object's movement trajectory that is located within the perception overlap area between the first sensing device and one or more other sensing devices. When the target object moves to the second position, the target object may subsequently move out of the perception area of ​​the first sensing device, and another sensing device (such as the second sensing device described below) may be required to continue sensing the target object. At this time, the sensing function network element needs to determine which specific sensing device will continue to sense the target object, that is, it needs to determine the second sensing device.

[0246] In one possible design, when the perception measurement result of the first perception device is the perception measurement result of the target object, the perception function network element can determine the position of the target object after continuous movement based on the perception measurement result, such as determining that the target object moves to the second position.

[0247] In another possible design, when the perception measurement result of the first perception device is the perception measurement result of all perception areas of the first perception device, the perception function network element can determine the perception measurement result of the target object from the perception measurement result based on the characteristic information of the target object, and then determine the position of the target object after continuous movement based on the perception measurement result of the target object, such as determining that the target object moves to the second position.

[0248] In another possible design, the perception function network element can also determine the second position according to the preset movement trajectory of the target object, and determine whether the target object moves to the second position according to the perception measurement result of the first perception device.

[0249] In an actual communication scenario, the actual movement trajectory of the target object may deviate from the preset movement trajectory. When the target object moves near the second position, it can be considered that the target object has moved to the second position.

[0250] Step 905: The perception function network element sends a second request to the second perception device corresponding to the second location; correspondingly, the second perception device receives the second request from the perception function network element.

[0251] When the perception function network element determines that the target object moves to a second position, the perception function network element may determine a second perception device according to the second position, and send a second request to the second perception device, requesting the second perception device to perform perception measurement.

[0252] In one possible design, the perception function network element may send a fourth request to the network storage function network element to request discovery of a perception device. The fourth request may include a second location. Based on the second location, the network storage function network element may determine one or more perception devices corresponding to the second location according to device information of each perception device, and send identification information of the one or more perception devices corresponding to the second location and perception area information of each perception device to the perception function network element via a fourth response. Based on the fourth response, the perception function network element selects a perception device from the one or more perception devices as the second perception device.

[0253] In another possible design, the perception function network element can determine the second perception device corresponding to the second location based on the received device information of each perception device based on the second location.

[0254] Optionally, when determining the second perception device, the perception function network element can also predict the movement trajectory of the target object based on the perception measurement results of the first perception device to obtain a prediction result; and determine the second perception device based on the prediction result and the perception area information of each perception device.

[0255] Optionally, the second request sent by the sensing function network element to the second sensing device may further include one or more of the following: characteristic information of the target object, the second location, and first indication information. The first indication information is used to instruct to activate sensing measurement in all sensing areas of the sensing device.

[0256] The perception function network element may carry the characteristic information and / or the second position of the target object in the second request sent to the second perception device, thereby instructing the second perception device to only perceive the target object, thereby reducing power consumption caused by perception. Alternatively, the perception function network element may carry the first indication information in the second request sent to the second perception device, thereby instructing the second perception device to activate perception measurement in all perception areas of the second perception device, thereby improving the accuracy of the perception measurement results.

[0257] Optionally, the perception function network element may also send a second request to the second perception device when determining that the target object enters the perception area of ​​the second perception device based on the characteristic information of the target object, the perception measurement results of the first perception device and the perception area information of the second perception device.

[0258] Step 906: The second sensing device sends the sensing measurement result to the sensing function network element; correspondingly, the sensing function network element receives the sensing measurement result from the second sensing device.

[0259] Among them, the second perception device can perform perception measurement according to the second request sent by the perception function network element, obtain the perception measurement result and send it to the perception function network element.

[0260] Optionally, the perception function network element may further send second instruction information to the second perception device, where the second instruction information is used to instruct the second perception device to stop the perception measurement. The second perception device stops the perception measurement according to the second instruction information.

[0261] Exemplarily, the perception function network element may send second indication information to the second perception device when it determines that the target object leaves the perception area of ​​the second perception device based on the perception measurement result of the second perception device and the perception area information of the second perception device.

[0262] In another example, the perception function network element can also predict the movement trajectory of the target object based on the received perception measurement results. When it is determined according to the prediction results that the target object is about to leave the perception area of ​​the second perception device, the perception function network element can send a second indication information to the second perception device.

[0263] In the method shown in FIG. 9 , the target object's perception measurement process is described using an example in which the sensing devices corresponding to the target object during movement include a first sensing device and a second sensing device, with the first sensing device being the starting sensing device (i.e., the first sensing device corresponding to the target object during movement). In actual communication, the target object may correspond to multiple sensing devices during movement. The perception measurement description of the starting sensing device among the multiple sensing devices can refer to the description of the first sensing device described above, and the perception measurement description of the other sensing devices among the multiple sensing devices can refer to the description of the second sensing device described above, and no further details are given.

[0264] Optionally, the starting perception device may not be the first perception device mentioned above. For example, before the target object moves into the perception area of ​​the first perception device, it may also move within the perception area of ​​the third perception device. In this case, the third perception device may be considered as the starting perception device.

[0265] At this time, the third request sent by the application function network element to the perception function network element carries the third position, not the first position, that is, the third request carries the starting position of the target object (or it can also be called the initial position). The perception function network element can refer to the above-mentioned method of determining the first perception device according to the first position, determine the third perception device according to the third position, and send the eleventh request to the third perception device. The third perception device performs perception measurement on the target object according to the eleventh request and sends the perception measurement result to the perception function network element. When the perception function network element determines that the target object has moved to the first position based on the characteristic information of the target object and the perception measurement result of the third perception device, it sends the first request to the first perception device corresponding to the first position, and the first perception device continues to perform perception measurement on the target object.

[0266] The eleventh request may be used to request a perception measurement. Optionally, the eleventh request may further include one or more of the following: characteristic information of the target object, the third position, and the first indication information.

[0267] Among them, the description of the perception function network element determining that the target object moves to the first position based on the characteristic information of the target object and the perception measurement results of the third perception device can refer to the relevant description of the perception function network element determining that the target object moves to the second position based on the characteristic information of the target object and the perception measurement results of the first perception device in the above step 904, and will not be repeated here.

[0268] Based on the method shown in FIG9 , the target object does not participate in the perception measurement process, and the target object may not have 3GPP UE identification information. The perception function network element can determine which target object needs to be perceived and measured based on the characteristic information of the target object, the first position and other auxiliary information provided by the application function network element, and then dynamically select a suitable perception device based on the position of the target object during movement, or select a suitable perception device based on a preset movement trajectory, such as selecting a first perception device based on the first position and selecting a second perception device based on the second position, and dynamically configure / activate the perception measurement operations of the first perception device and the second perception device through the first request and the second request, thereby ensuring that the target object is always within the perception area of ​​the perception device during movement, thereby achieving continuous perception of the target object and ensuring the continuity of the perception service.

[0269] Based on the method shown in Figure 9, the perception function network element can also determine the movement trajectory of the target object based on the perception measurement result of the first perception device and the second perception measurement result. The perception function network element can also send the movement trajectory of the target object to the application function network element.

[0270] When the perception measurement results of the first perception device and the second perception device are perception measurement results of the target object, the perception function network element may aggregate the perception measurement results to determine the continuous movement trajectory of the target object. Alternatively, when the perception measurement results of the first perception device and the second perception device are perception measurement results of all perception areas of their corresponding perception devices, the perception function network element may determine the perception measurement results of the target object from the perception measurement results based on the characteristic information of the target object, and then aggregate the perception measurement results of the target object to determine the movement trajectory of the target object.

[0271] Optionally, if the perception measurement results received by the perception function network element show that there are multiple target objects (the multiple target objects have the same characteristic information), the perception function network element can also select the target object for which a moving trajectory needs to be generated from the multiple target objects based on the starting position of the target object, and then generate the moving trajectory of the target object.

[0272] Optionally, if the perception measurement results received by the perception function network element show that there are multiple target objects at the starting position (the multiple targets have the same characteristic information and the same starting position), after a period of time, the multiple target objects separate and there are multiple moving trajectories. The perception function network element can select the target object for which a moving trajectory needs to be generated from the multiple target objects based on the position information of the target object for which a moving trajectory needs to be generated sent by the application function network element, and then determine the moving trajectory of the target object from the multiple moving trajectories. Alternatively, the perception function network element can also send the multiple moving trajectories to the application function network element, and the application function network element or a third-party application can generate the position information of the target object for which a moving trajectory needs to be generated, and select the moving trajectory of the target object from the multiple moving trajectories.

[0273] The application function network element may obtain the target object's location information through other technical means. For example, during the movement of the target object, the application layer periodically sends its current location to the application function network element or a third-party application. Alternatively, during the movement of the target object, the application function network element or a third-party application obtains the target object's current location information from a sensing device such as a camera or radar.

[0274] For example, as shown in Figure 10, the perception function network element can determine the target object's movement trajectory based on the target object's characteristic information and the target object's starting position. As shown in Figure 11, when there are multiple target objects at the starting position, after a period of time, the multiple target objects separate and multiple movement trajectories exist. The perception function network element, the application function network element, or a third-party application can generate the position information of the target object's movement trajectory as needed to determine the movement trajectory of the target object.

[0275] Optionally, the perception function network element may carry the moving trajectory of the target object in a third response and send it to the application function network element.

[0276] Optionally, before the perception function network element sends the target object's movement trajectory to the application function network element, the perception function network element may further calibrate the target object's movement trajectory based on the target object's position information sent by the application function network element, and send the calibrated movement trajectory to the application function network element. Alternatively, the perception function network element may calibrate the target object's movement trajectory based on a preset movement trajectory of the target object, and send the calibrated movement trajectory to the application function network element.

[0277] Optionally, when the application function network element receives the moving trajectory of the target object sent by the perception function network element, it can also calibrate the moving trajectory of the target object based on one or more of the following: characteristic information of the target object, preset moving trajectory of the target object, and location information of the target object.

[0278] Optionally, the perception function network element may also calibrate the second position based on the target object's position information sent by the application function network element. That is, the perception function network element searches for the target object from the perception measurement results based on the feature information and then determines the target object's second position. When the position information provided by the application function network element is introduced, the perception function network element can more accurately search for the target object, thereby achieving calibration of the second position.

[0279] Based on the above description, the following takes the application function network element as AF, the perception function network element as SF, the network storage function network element as NRF, and the corresponding perception devices of the target object during movement as an example, and refers to the following Figure 12 to illustrate the perception measurement method shown in Figure 9.

[0280] FIG12 is a flow chart of a perception measurement method provided in an embodiment of the present application. As shown in FIG12 , the perception measurement method may include:

[0281] Step 1201: AF sends a sensing service request to SF; correspondingly, SF receives the sensing service request from AF.

[0282] The sensing service request may include one or more of the following: characteristic information of the target object, the starting location of the target object, the start time of the sensing measurement, the end time of the sensing measurement, and the preset movement trajectory of the target object. The description of this sensing service request can refer to the description of the third request in step 901 above and is not repeated here.

[0283] Optionally, before the AF sends the sensing service request to the SF, the AF may determine the feature information of the target object and the starting position of the target object based on step 1200c.

[0284] In which, in step 1200c, before performing perception measurement on the target object, AF may request the network to perform perception measurement on objects in a certain area (such as sending a fifth request including area information of the first area to SF to request perception measurement of the first area), SF selects a suitable perception device to trigger perception measurement of the area, and sends the perception measurement result to AF, for AF to determine which object in the area is the target object that needs to be perceived, that is, to determine one or more of the following information of the target object: characteristic information of the target object, and the starting position of the target object.

[0285] Optionally, the sensing device may register its own device information with the NRF through the AMF based on steps 1200a and 1200b. Alternatively, the sensing device may also send device information to the SF through the AMF.

[0286] When it is necessary to perform perception measurement on an object in a certain area, the SF can send a perception device discovery request to the NRF to request the discovery of perception devices. The request can carry the area information of the area. Based on the received perception device discovery request, the NRF can determine the perception devices corresponding to the area based on the device information of each perception device, and indicate it to the SF through a perception device discovery response. The SF can determine the perception devices corresponding to the area based on the perception device discovery response, thereby triggering the perception measurement. Alternatively, the SF can also determine the perception devices corresponding to the area based on the area information of the area and the device information of each perception device received, thereby triggering the perception measurement.

[0287] The device information of the sensing device may include identification information of the sensing device and sensing area information of the sensing device. Optionally, it may also include location information of the sensing device. The location information of the sensing device and the sensing area information of the sensing device may also be collectively referred to as the sensing capability of the sensing device.

[0288] Among them, the description of the perception device discovery request and the perception device discovery response can refer to the relevant description of the fourth request and the fourth response in the above step 901, and will not be repeated here.

[0289] Step 1202: SF sends a sensing device discovery request to NRF, and NRF sends a sensing device discovery response to SF; correspondingly, NRF receives the sensing device discovery request from SF, and SF receives the sensing device discovery response from NRF.

[0290] The sensor device discovery request may include the starting location of the target object. Based on the starting location, the NRF can determine the sensor device 1 corresponding to the starting location according to the device information of each sensor device, and send the identification information of the sensor device 1 to the SF via the sensor device discovery response. The NRF can also send the sensing area information of the sensor device 1 to the SF via the sensor device discovery response.

[0291] Among them, the description of the starting position, the perception device discovery request and the perception device discovery response can refer to the relevant description of the first position, the fourth request and the fourth response in the above step 902, and will not be repeated here.

[0292] Step 1203: SF sends a perception measurement request to perception device 1; correspondingly, perception device 1 receives the perception measurement request from SF.

[0293] The perception measurement request may include characteristic information of the target object and the starting location of the target object. Alternatively, the perception measurement request may include first indication information indicating activation of perception measurement in all perception areas of the perception device. A description of the perception measurement request can refer to the description of the first request sent to the first perception device in step 902 above and is not repeated here.

[0294] Step 1204: Perception device 1 performs perception measurement.

[0295] Step 1205 : Perception device 1 reports the perception measurement result to SF; correspondingly, SF receives the perception measurement result from perception device 1 .

[0296] The description of this step may refer to the relevant description of step 903 above and will not be repeated here.

[0297] Step 1206: SF determines to trigger the reselection process of the sensing device based on the sensing measurement result of the sensing device 1.

[0298] Among them, SF can determine the movement trajectory of the target object from the perception measurement results of the perception device 1 based on the characteristic information of the target object and / or the starting position of the target object. When the target object leaves or is about to leave the perception area of ​​the perception device 1, SF can trigger the reselection process of the perception device.

[0299] Optionally, as shown in step 1206a, SF may further send second instruction information to the sensing device 1 to instruct the sensing device 1 to stop performing the sensing measurement.

[0300] Step 1207: SF sends a perception device sending request to NRF, and NRF sends a perception device discovery response to SF; correspondingly, NRF receives the perception device sending request from SF, and SF receives the perception device discovery response from NRF.

[0301] The sensor device discovery request may include the second location of the target object. Based on the second location, the NRF may determine the sensor device 2 corresponding to the second location according to the device information of each sensor device, and send the identification information of the sensor device 2 to the SF via a sensor device discovery response. The NRF may also send the sensing area information of the sensor device 2 to the SF via the sensor device discovery response.

[0302] Among them, the description of the second position, the perception device discovery request and the perception device discovery response can refer to the relevant description of the second position, the fourth request and the fourth response in the above steps 904 and 905, and will not be repeated here.

[0303] Step 1208: SF sends a perception measurement request to perception device 2. Correspondingly, perception device 2 receives the perception measurement request from SF.

[0304] The perception measurement request may include characteristic information of the target object and the second location of the target object. Alternatively, the perception measurement request may include first indication information indicating activation of perception measurement in all perception areas of the perception device. A description of the perception measurement request can refer to the description of the second request sent to the second perception device in step 905 above and is not repeated here.

[0305] Step 1209: Perception device 2 performs perception measurement.

[0306] Step 1210: Perception device 2 reports the perception measurement result to SF; correspondingly, SF receives the perception measurement result from perception device 2.

[0307] The description of this step may refer to the relevant description of the above step 906 and will not be repeated here.

[0308] Optionally, as shown in step 1210a, SF may further send second instruction information to the sensing device 2 to instruct the sensing device 2 to stop performing the sensing measurement.

[0309] Step 1211: SF aggregates the sensing measurement results to generate a moving trajectory of the target object.

[0310] Step 1212: The SF sends a sensing service response to the AF; correspondingly, the AF receives the sensing service response from the SF.

[0311] The perception service response includes the target object's movement trajectory. The perception service response can refer to the aforementioned description of the third response and is not repeated here. Steps 1211 and 1212 can also refer to the aforementioned description of the perception function network element sending the target object's movement trajectory to the application function network element and are not repeated here.

[0312] Unlike the above-mentioned Figures 9 to 12, where the perception function network element determines that the terminal device moves to a certain position based on the perception measurement results or the preset moving trajectory of the target object, and sends a request for requesting perception measurement to the perception device corresponding to the position, as shown in Figure 13, the perception function network element can also determine multiple perception devices (such as the first perception device and the second perception device) based on the preset moving trajectory of the target object, and send a request for requesting perception measurement to the multiple perception devices to realize perception measurement of the target object.

[0313] FIG13 is a flow chart of a perception measurement method provided in an embodiment of the present application. As shown in FIG13 , the method may include:

[0314] Step 1301: The perception function network element obtains a preset movement trajectory of a target object.

[0315] Optionally, the perception function network element may obtain the preset movement trajectory of the target object from the application function network element or the mobility management network element.

[0316] The application function network element may send the preset movement trajectory of the target object to the perception function network element. Alternatively, the application function network element may send the preset movement trajectory of the target object and the first position of the target object to the network open network element. The network open network element selects a mobility management network element whose coverage range includes the first position of the target object based on the first position of the target object, and then sends the preset movement trajectory of the target object to the mobility management network element. The mobility management network element then sends the preset movement trajectory of the target object to the perception function network element.

[0317] Optionally, the application function network element may carry the preset moving trajectory of the target object in the third request and send it to the perception function network element, or may also send the third request to the perception function network element through the network open network element and the mobility management network element.

[0318] The third request may be used to request acquisition of the movement trajectory of the target object. The third request may also be referred to as a perception service request.

[0319] Optionally, the third request may further include one or more of the following: characteristic information of the target object, the first position of the target object, the start time of the perception measurement, and the end time of the perception measurement. For a description of the characteristic information of the target object and the first position of the target object, refer to the description in FIG. 9 above and are not repeated here.

[0320] Optionally, before the perception function network element obtains the characteristic information of the target object, the application function network element may also send a fifth request to the perception function network element to request perception measurement of the first area. The fifth request may include the area information of the first area. Based on the fifth request, the perception function network element may send a sixth request to the perception device corresponding to the first area to request perception measurement. Based on the sixth request, the perception device may perform perception measurement on the first area and send the perception measurement result to the perception function network element. The perception function network element then sends the perception measurement result corresponding to the first area to the application function network element. Based on the perception measurement result of the first area, the application function network element may determine one or more of the following information of the target object that needs to be perceived and measured in the first area: characteristic information of the target object and the first position of the target object. The application function network element may then send the third request to the perception function network element, or send the third request to the perception function network element via the mobility management network element.

[0321] Among them, the description of the sensing device and device information can refer to the relevant description in the above step 901 and will not be repeated here.

[0322] Step 1302: The perception function network element determines a first perception device and a second perception device according to a preset movement trajectory.

[0323] The sensing areas of the first sensing device and the second sensing device cover the preset movement trajectory.

[0324] In one possible design, the perception function network element may send a seventh request to the network storage function network element to request discovery of a perception device. The seventh request may include a preset mobile trajectory. Based on the preset mobile trajectory, the network storage function network element may determine the first perception device and the second perception device corresponding to the preset mobile trajectory according to the device information of each perception device, and send identification information of the first perception device and the second perception device corresponding to the preset mobile trajectory to the perception function network element via a seventh response. The seventh response may also include perception area information of the first perception device and the second perception device. Based on the seventh response, the perception function network element may determine the first perception device and the second perception device.

[0325] In another possible design, the perception function network element can determine the first perception device and the second perception device corresponding to the preset movement trajectory based on the device information sent by each perception device based on the preset movement trajectory.

[0326] Step 1303: The perception function network element sends a first request to the first perception device; correspondingly, the first perception device receives the first request from the perception function network element.

[0327] The first request may be used to request a perception measurement.

[0328] Optionally, the first request may include one or more of the following: characteristic information of the target object, and first indication information; wherein the first indication information is used to instruct activation of perception measurement in all perception areas of the perception device.

[0329] Optionally, the first request may further include the first location. When the third request includes the first location of the target object, the sensing function network element may determine the first location based on the third request. Alternatively, the sensing function network element may determine the first location based on a preset movement trajectory.

[0330] The perception function network element may carry the characteristic information and / or the first position of the target object in the first request, thereby instructing the first perception device to only perceive the target object, thereby reducing power consumption caused by perception. Alternatively, the perception function network element may carry the first indication information in the first request, thereby instructing the first perception device to activate perception measurement in all perception areas of the perception device, thereby improving the accuracy of the perception measurement results.

[0331] Step 1304: The perception function network element sends a second request to the second perception device; correspondingly, the second perception device receives the second request from the perception function network element.

[0332] The second request may be used to request a perception measurement.

[0333] Optionally, the second request may include one or more of the following: characteristic information of the target object, and first indication information; wherein the first indication information is used to instruct activation of perception measurement in all perception areas of the perception device.

[0334] Optionally, the second request may further include a second location, wherein the perception function network element may determine the second location according to a preset movement trajectory.

[0335] The perception function network element may carry the characteristic information and / or the second location of the target object in the second request to instruct the second perception device to only perceive the target object, thereby reducing power consumption caused by perception. Alternatively, the perception function network element may carry the first indication information in the second request to instruct the second perception device to activate perception measurement in all perception areas of the second perception device, thereby improving the accuracy of the perception measurement results.

[0336] Optionally, the perception function network element may simultaneously activate the perception measurements of the first perception device and the second perception device through the first request and the second request. Alternatively, the perception function network element may first activate the perception measurement of the first perception device through the first request, and then activate the perception measurement of the second perception device in combination with the movement trajectory of the target object.

[0337] Exemplarily, the perception function network element can determine that when the target object enters the perception area of ​​the second perception device based on the characteristic information of the target object, the perception measurement results of the perception device and the perception area information of the perception device, it sends a second request to the second perception device to activate the perception measurement of the second perception device.

[0338] Step 1305: The first sensing device sends the sensing measurement result to the sensing function network element; correspondingly, the sensing function network element receives the sensing measurement result from the first sensing device.

[0339] Among them, the first perception device can perform perception measurement according to the first request sent by the perception function network element, obtain the perception measurement result and send it to the perception function network element.

[0340] Optionally, the perception function network element may further send second instruction information to the first perception device, where the second instruction information is used to instruct the first perception device to stop the perception measurement. The first perception device stops the perception measurement according to the second instruction information.

[0341] Exemplarily, the perception function network element may send second indication information to the first perception device and the second perception device simultaneously when it is necessary to end the perception measurement of the target object.

[0342] In another example, the perception function network element may also send second indication information to the first perception device when it determines that the target object leaves the perception area of ​​the first perception device based on the perception measurement result of the first perception device and the perception area information of the first perception device.

[0343] In another example, the perception function network element can also predict the movement trajectory of the target object based on the perception measurement results of the first perception device. When it is determined according to the prediction results that the target object is about to leave the perception area of ​​the first perception device, the perception function network element can send a second indication information to the first perception device.

[0344] Step 1306: The second sensing device sends the sensing measurement result to the sensing function network element; correspondingly, the sensing function network element receives the sensing measurement result from the second sensing device.

[0345] Among them, the second perception device can perform perception measurement according to the second request sent by the perception function network element, obtain the perception measurement result and send it to the perception function network element.

[0346] Optionally, the perception function network element may further send second instruction information to the second perception device, where the second instruction information is used to instruct the second perception device to stop the perception measurement. The second perception device stops the perception measurement according to the second instruction information.

[0347] Exemplarily, the perception function network element may send second indication information to the first perception device and the second perception device simultaneously when it is necessary to end the perception measurement of the target object.

[0348] In another example, the perception function network element may also send second indication information to the second perception device when it determines that the target object leaves the perception area of ​​the second perception device based on the perception measurement result of the second perception device and the perception area information of the second perception device.

[0349] In another example, the perception function network element can also predict the movement trajectory of the target object based on the perception measurement results of the second perception device. When it is determined according to the prediction results that the target object is about to leave the perception area of ​​the second perception device, the perception function network element can send a second indication information to the second perception device.

[0350] Based on the method shown in FIG13 above, the target object does not participate in the perception measurement process, and the target object may not have identification information. The perception function network element can determine which target object needs to be perceived and measured based on the characteristic information of the target object, the first position and other auxiliary information provided by the application function network element, and then select multiple appropriate perception devices based on the preset movement trajectory of the target object, and dynamically configure / activate the perception measurement operation of the perception device through a request for perception measurement (such as a first request, a second request, etc.), thereby ensuring that the target object is always within the perception area of ​​the perception device during movement, thereby achieving continuous perception of the target object and ensuring the continuity of the perception service.

[0351] Based on the method shown in FIG13 , the sensing function network element can also determine the movement trajectory of the target object based on the sensing measurement results of multiple sensing devices. The sensing function network element can also send the movement trajectory of the target object to the application function network element.

[0352] Among them, the description of the perception function network element determining the moving trajectory of the target object based on the perception measurement results of multiple perception devices and sending it to the application function network element can refer to the relevant description of the perception function network element determining the moving trajectory of the target object based on the perception measurement results of the first perception device and the second perception device and sending it to the application function network element, and will not be repeated here.

[0353] Optionally, when the application function network element receives the moving trajectory of the target object sent by the perception function network element, it can also calibrate the moving trajectory of the target object based on one or more of the following: characteristic information of the target object, preset moving trajectory of the target object, and location information of the target object.

[0354] Optionally, the perception function network element may also calibrate the second position based on the target object's position information sent by the application function network element. That is, the perception function network element searches for the target object from the perception measurement results based on the feature information and then determines the target object's second position. When the position information provided by the application function network element is introduced, the perception function network element can more accurately search for the target object, thereby achieving calibration of the second position.

[0355] Based on the above description, the following takes the application function network element as AF, the perception function network element as SF, the network storage function network element as NRF, and the corresponding perception devices of the target object during movement as an example, and refers to the following Figure 14 to illustrate the perception measurement method shown in Figure 13.

[0356] FIG14 is a flow chart of a perception measurement method provided in an embodiment of the present application. As shown in FIG14 , the perception measurement method may include:

[0357] Step 1401: AF sends a sensing service request to SF; correspondingly, SF receives the sensing service request from AF.

[0358] The sensing service request may include one or more of the following: characteristic information of the target object, the starting location of the target object, the start time of the sensing measurement, the end time of the sensing measurement, and the preset movement trajectory of the target object. The description of this sensing service request can refer to the description of the third request in step 1301 above and is not repeated here.

[0359] Optionally, before the AF sends a sensing service request to the SF, the AF may determine the feature information of the target object and the starting position of the target object based on step 1400c.

[0360] Optionally, the sensing device may register its own device information with the NRF via the AMF based on steps 1400a and 1400b. Alternatively, the sensing device may send device information to the SF via the AMF.

[0361] Among them, the description of steps 1400a, 1400b, and 1400c can refer to the relevant description of steps 1200a, 1200b, and 1200c in the above step 1201, and will not be repeated here.

[0362] Step 1402: SF sends a sensing device discovery request to NRF, and NRF sends a sensing device discovery response to SF; correspondingly, NRF receives the sensing device discovery request from SF, and SF receives the sensing device discovery response from NRF.

[0363] The sensor device discovery request may include a preset movement trajectory of the target object. Based on the preset movement trajectory, the NRF can determine the sensor devices 1 and 2 corresponding to the preset movement trajectory according to the device information of each sensor device, and send the identification information of sensor devices 1 and 2 to the SF via a sensor device discovery response. The NRF can also send the sensing area information of sensor devices 1 and 2 to the SF via the sensor device discovery response.

[0364] Among them, the description of the perception device discovery request and the perception device discovery response can refer to the relevant description of the seventh request and the seventh response in the above step 1302, and will not be repeated here.

[0365] Step 1403: SF sends a perception measurement request to perception device 1; correspondingly, perception device 1 receives the perception measurement request from SF.

[0366] The perception measurement request may include characteristic information and / or the first location of the target object. Alternatively, the perception measurement request may include first indication information indicating activation of perception measurement in all perception areas of the perception device. A description of the perception measurement request may refer to the description of the first request in step 1303 above and is not repeated here.

[0367] Step 1404: Perception device 1 performs perception measurement.

[0368] Step 1405 : Perception device 1 reports the perception measurement result to SF; correspondingly, SF receives the perception measurement result from perception device 1 .

[0369] The description of this step may refer to the relevant description of the above step 1305 and will not be repeated here.

[0370] Step 1406: SF sends a perception measurement request to perception device 2. Correspondingly, perception device 2 receives the perception measurement request from SF.

[0371] The perception measurement request may include characteristic information of the target object and / or the second location of the target object. Alternatively, the perception measurement request may include first indication information indicating activation of perception measurement in all perception areas of the perception device. A description of the perception measurement request can refer to the description of the second request in step 1304 above and is not repeated here.

[0372] Step 1407: Perception device 2 performs perception measurement.

[0373] Step 1408: Perception device 2 reports the perception measurement result to SF; correspondingly, SF receives the perception measurement result from perception device 2.

[0374] The description of this step may refer to the relevant description of the above step 1306 and will not be repeated here.

[0375] Step 1409: SF aggregates the sensing measurement results to generate a moving trajectory of the target object.

[0376] Step 1410: The SF sends a sensing service response to the AF; correspondingly, the AF receives the sensing service response from the SF.

[0377] The sensing service response includes the target object's movement trajectory. The response to the sensing service can refer to the aforementioned description of the third response and is not repeated here. The description of steps 1409 and 1410 can also refer to the aforementioned description of the sensing function network element sending the target object's movement trajectory to the application function network element and is not repeated here.

[0378] Optionally, as shown in step 1411, SF may further send second instruction information to the sensing device 1 and the sensing device 2 to instruct the sensing device 1 and the sensing device 2 to stop performing the sensing measurement.

[0379] Different from the above-mentioned Figures 9 to 14 in which the core network (such as the perception function network element and the network storage function network element) determines the various perception devices corresponding to the target object, as shown in Figure 15, each perception device can exchange its own device information, and the perception device selects the next perception device for the target object based on each perception device, thereby realizing continuous perception of the target object.

[0380] FIG15 is a flow chart of a perception measurement method provided in an embodiment of the present application. As shown in FIG15 , the method may include:

[0381] Step 1501: The perception function network element obtains feature information of the target object.

[0382] The description of step 1501 may refer to the above description of step 901 and will not be repeated here.

[0383] Step 1502: The perception function network element sends a first request to a first perception device corresponding to a first position of the target object; correspondingly, the first perception device receives the first request from the perception function network element.

[0384] The first request is used to request a perception measurement, and the first request includes feature information of the target object.

[0385] Optionally, the first request sent by the perception function network element to the first perception device may also include one or more of the following: a first position, a preset movement trajectory of the target object.

[0386] The description of step 1502 may refer to the above description of step 902 and will not be repeated here.

[0387] Step 1503: The first sensing device performs sensing measurement on the target object to obtain a sensing measurement result.

[0388] The first sensing device may measure the target object according to the characteristic information of the target object to obtain a sensing measurement result of the target object.

[0389] Step 1504: The first sensing device sends the sensing measurement result to the sensing function network element; correspondingly, the sensing function network element receives the sensing measurement result from the first sensing device.

[0390] The description of step 1503 and step 1504 may refer to the above description of step 903 and will not be repeated here.

[0391] Step 1505: The first sensing device determines that the target object moves to the second position based on the characteristic information of the target object and the sensing measurement result.

[0392] The second position may be a position in the target object's movement trajectory that is within the overlapping perception area between the first sensing device and one or more other sensing devices. When the target object moves to the second position, it may subsequently move out of the perception area of ​​the first sensing device, and another sensing device (such as the second sensing device described below) may be required to continue sensing the target object. In this case, the first sensing device needs to determine which sensing device will continue sensing the target object, that is, it needs to determine the second sensing device.

[0393] In one possible design, the first perception device may determine the position of the target object after continuous movement based on the perception measurement result after performing perception measurement on the target object, such as determining that the target object moves to the second position.

[0394] In another possible design, the first sensing device may also determine the second position according to a preset movement trajectory of the target object, and determine whether the target object moves to the second position according to the sensing measurement result of the first sensing device.

[0395] In an actual communication scenario, the actual movement trajectory of the target object may deviate from the preset movement trajectory. When the target object moves near the second position, it can be considered that the target object has moved to the second position.

[0396] Step 1506: The first sensing device sends third indication information to the second sensing device corresponding to the second position; correspondingly, the second sensing device receives the third indication information from the first sensing device.

[0397] The third indication information may trigger the second sensing device to perform sensing measurement on the target object. The third indication information may include identification information of the target object.

[0398] Optionally, the third indication information may also be used to instruct reporting of the perception measurement results of the target object to the perception function network element; the third indication information may also include identification information of the perception function network element. It is understood that the identification information of the perception function network element may be specifically represented by a device identifier, address, port number, etc., and this application does not limit this.

[0399] When the first sensing device determines that the target object moves to the second position, the first sensing device may determine the second sensing device according to the second position and send third indication information to the second sensing device.

[0400] Optionally, a sensing device in the network can exchange its own device information with other sensing devices, that is, a first sensing device can receive device information from one or more sensing devices.

[0401] Among them, sensing devices can exchange device information through the Xn interface or PC5 interface.

[0402] In one possible design, the first sensing device may determine the second sensing device from one or more sensing devices based on the sensing measurement result and device information.

[0403] Among them, the first perception device can determine that the target object moves to the second position based on the perception measurement result, and then determine the second perception device corresponding to the second position from the one or more perception devices based on the received device information of the one or more perception devices.

[0404] In another possible design, the first perception device can predict the movement trajectory of the target object based on the perception measurement results to obtain a prediction result, and determine the second perception device from one or more perception devices based on the prediction result and device information.

[0405] Among them, the first perception device can predict the movement trajectory of the target object based on the perception measurement results, obtain a prediction result, determine the second position based on the prediction result, and then determine the second perception device corresponding to the second position from one or more perception devices based on the device information received from one or more perception devices.

[0406] In another possible design, the first sensing device may determine the second sensing device from one or more sensing devices based on a preset movement trajectory and device information of the target object.

[0407] The first sensing device may determine the second position according to a preset movement trajectory, and then determine the second sensing device corresponding to the second position from the one or more sensing devices according to the received device information of the one or more sensing devices.

[0408] In another possible design, the first perception device may also determine the second perception device from one or more perception devices based on the perception measurement result, the preset movement trajectory of the target object, and the device information.

[0409] Among them, the first sensing device can determine the second position according to the preset movement trajectory, determine that the target object has moved to the second position according to the perception measurement result, and then determine the second sensing device corresponding to the second position from one or more sensing devices based on the device information received from one or more sensing devices.

[0410] Optionally, the third indication information sent by the first sensing device to the second sensing device may further include one or more of the following: the second position, and a preset movement trajectory of the target object.

[0411] Optionally, the first perception device may also send third indication information to the second perception device when determining that the target object enters the perception area of ​​the second perception device based on the feature information of the target object, the perception measurement result of the first perception device and the perception area information of the second perception device.

[0412] Step 1507: The second sensing device performs sensing measurement on the target object to obtain a sensing measurement result.

[0413] Step 1508: The second sensing device sends the sensing measurement result to the sensing function network element.

[0414] The description of step 1507 and step 1508 can refer to the relevant description of the above step 906 and will not be repeated here.

[0415] The method illustrated in FIG. 15 above describes the target object's perception and measurement process using an example in which the target object's corresponding sensing devices during movement include a first sensing device and a second sensing device, with the first sensing device being the starting sensing device (i.e., the first sensing device corresponding to the target object during movement). In actual communication, the target object may correspond to multiple sensing devices during movement, such as a fourth sensing device.

[0416] Among them, the second perception device can determine that the target object has moved to the fourth position based on the characteristic information and perception measurement results of the target object, and send fourth indication information to the fourth perception device corresponding to the fourth position. The fourth perception device measures the target object according to the fourth indication information and sends the perception measurement results to the perception function network element.

[0417] Among them, the fourth indication information may include characteristic information of the target object and identification information of the perception function network element.

[0418] Optionally, the fourth indication information may further include one or more of the following: a fourth position, a preset movement trajectory of the target object.

[0419] Among them, the description of "the second perception device can determine that the target object moves to the fourth position based on the characteristic information and perception measurement results of the target object, and send fourth indication information to the fourth perception device corresponding to the fourth position, and the fourth perception device performs perception measurement on the target object according to the fourth indication information, and sends the perception measurement results to the perception function network element" can refer to the relevant description of "the first perception device determines that the target object moves to the second position based on the characteristic information and perception measurement results of the target object, sends third indication information to the second perception device corresponding to the second position, and the second perception device performs perception measurement on the target object according to the third indication information, and sends the perception measurement results to the perception function network element" in the above steps 1505 to 1508, and will not be repeated here.

[0420] Based on the method shown in FIG15 above, the target object does not participate in the perception measurement process, and the target object may not have identification information. The perception function network element can determine which target object needs to be perceived and measured based on the feature information of the target object, the first position and other auxiliary information provided by the application function network element, and then trigger the first perception device to perceive and measure the target object. Since each perception device can exchange its own device information, the first perception device can select the next perception device for the target object based on the received device information, such as the second perception device. The second perception device can also select the next perception device for the target object based on the received device information, such as the fourth perception device, thereby ensuring that the target object is always within the perception area of ​​the perception device during movement, achieving continuous perception of the target object, and ensuring the continuity of the perception service.

[0421] Based on the method in FIG15 , the perception function network element can also determine the target object's movement trajectory based on the perception measurement results of the first and second perception devices. The perception function network element can also send the target object's movement trajectory to the application function network element. For details, please refer to the aforementioned description of the perception function network element determining the target object's movement trajectory based on the perception measurement results of the first and second perception devices and sending it to the application function network element, and will not be repeated here.

[0422] Optionally, when the application function network element receives the moving trajectory of the target object sent by the perception function network element, it can also calibrate the moving trajectory of the target object based on one or more of the following: characteristic information of the target object, preset moving trajectory of the target object, and location information of the target object.

[0423] Optionally, the perception function network element may also calibrate the second position based on the target object's position information sent by the application function network element. That is, the perception function network element searches for the target object from the perception measurement results based on the feature information and then determines the target object's second position. When the position information provided by the application function network element is introduced, the perception function network element can more accurately search for the target object, thereby achieving calibration of the second position.

[0424] Based on the above description, the following takes the application function network element as AF, the perception function network element as SF, the network storage function network element as NRF, and the corresponding perception devices of the target object during movement as an example, and refers to the following Figure 16 to illustrate the perception measurement method shown in Figure 15.

[0425] FIG16 is a flow chart of a perception measurement method provided in an embodiment of the present application. As shown in FIG16 , the perception measurement method may include:

[0426] Step 1601: AF sends a sensing service request to SF; correspondingly, SF receives the sensing service request from AF.

[0427] The perception service request may include one or more of the following: characteristic information of the target object, the starting position of the target object, the starting time of the perception measurement, the ending time of the perception measurement, and the preset movement trajectory of the target object.

[0428] Optionally, before the AF sends a sensing service request to the SF, the AF may determine the feature information of the target object and the starting position of the target object based on step 1600c.

[0429] The description of step 1600c may refer to the relevant description of step 1200c in the above step 1201 and will not be repeated here.

[0430] Optionally, each sensing device may also exchange its own device information based on step 1600a and step 1600b.

[0431] Step 1602: SF sends a sensing device discovery request to NRF, and NRF sends a sensing device discovery response to SF; correspondingly, NRF receives the sensing device discovery request from SF, and SF receives the sensing device discovery response from NRF.

[0432] The sensor device discovery request may include the starting location of the target object. Based on the starting location, the NRF can determine the sensor device 1 corresponding to the starting location according to the device information of each sensor device, and send the identification information of the sensor device 1 to the SF via the sensor device discovery response. The NRF can also send the sensing area information of the sensor device 1 to the SF via the sensor device discovery response.

[0433] Step 1603: SF sends a perception measurement request to perception device 1; correspondingly, perception device 1 receives the perception measurement request from SF.

[0434] The perception measurement request may be used to request perception measurement, and the perception measurement request may include feature information of the target object.

[0435] Optionally, the perception measurement request may further include one or more of the following: a starting position, and a preset moving trajectory of the target object.

[0436] Step 1604: Perception device 1 performs perception measurement.

[0437] Step 1605 : Perception device 1 reports the perception measurement result to SF; correspondingly, SF receives the perception measurement result from perception device 1 .

[0438] The description of this step may refer to the relevant description of the above-mentioned step 1503 and step 1504, and will not be repeated here.

[0439] Step 1606: Perception device 1 determines to trigger a reselection process of the perception device based on the perception measurement result of perception device 1.

[0440] The sensing device 1 can determine the moving trajectory of the target object based on the sensing measurement result. When the target object leaves or is about to leave the sensing area of ​​the sensing device 1, the sensing device 1 can trigger a reselection process of the sensing device.

[0441] Step 1607 : Perception device 1 sends the context of the perception device to perception device 2 ; correspondingly, perception device 2 receives the context of the perception device from perception device 1 .

[0442] The context of the sensing device may include characteristic information of the target object and identification information of the SF. Optionally, the context of the sensing device may also include one or more of the following: a second location and a preset movement trajectory of the target object. The description of the context of the sensing device can refer to the description of the third indication information above and is not repeated here.

[0443] When sensing device 1 determines that the target object has moved to a second location based on the characteristic information of the target object and the sensing measurement results, it may send the sensing device context to sensing device 2 corresponding to the second location. For related descriptions, reference may be made to the descriptions of steps 1505 and 1506 above and are not repeated here.

[0444] Step 1608: Perception device 2 performs perception measurement.

[0445] Step 1609 : Perception device 2 reports the perception measurement result to SF; correspondingly, SF receives the perception measurement result from perception device 2 .

[0446] The description of step 1608 and step 1609 can refer to the relevant description of the above-mentioned step 1507 and step 1508, and will not be repeated here.

[0447] Step 1610: SF aggregates the sensing measurement results to generate a moving trajectory of the target object.

[0448] Step 1611: SF sends a sensing service response to AF; correspondingly, AF receives the sensing service response from SF.

[0449] The sensing service response includes the target object's movement trajectory. The response to the sensing service can refer to the aforementioned description of the third response and is not repeated here. The description of steps 1610 and 1611 can also refer to the aforementioned description of the sensing function network element sending the target object's movement trajectory to the application function network element and is not repeated here.

[0450] Unlike the aforementioned sensing and measurement of the target object based on its characteristic information as shown in Figures 9 to 16, continuous sensing and measurement of the target object can also be achieved based on its identification information and with the help of communication capabilities, as shown in Figure 17. For example, sensing devices that can provide a communication link (such as access network devices with sensing capabilities) can be used for sensing. When the target object switches its communication link, the switching of the sensing device can be triggered, thereby achieving continuous sensing of the target object.

[0451] FIG17 is a flow chart of a perception measurement method provided in an embodiment of the present application. As shown in FIG17 , the method may include:

[0452] Step 1701: The perception function network element sends a first request to the first access network device; correspondingly, the first access network device receives the first request from the perception function network element.

[0453] The first request may be used to request the first access network device to perform perception measurement on the target object.

[0454] Optionally, the first request sent by the perception function network element to the first access network device may include one or more of the following: identification information of the target object, characteristic information of the target object, the first location, first indication information, and a preset movement trajectory of the target object. The first indication information is used to indicate activation of perception measurement in all perception areas of the perception device.

[0455] The perception function network element may carry the identification information and / or characteristic information and / or the first location of the target object in a first request sent to the first access network device, thereby instructing the first access network device to only perceive the target object, thereby reducing the power consumption caused by perception. Alternatively, the perception function network element may carry first indication information in a first request sent to the first access network device, thereby instructing the first access network device to activate perception measurement in all perception areas of the first access network device, thereby improving the accuracy of the perception measurement results.

[0456] Optionally, the perception function network element may determine the first position of the target object according to the ninth request sent by the application function network element, or the perception function network element may also determine the first position of the target object through the mobility management network element.

[0457] Optionally, the perception function network element may determine the first access network device according to the following steps 1701a and 1701b:

[0458] Step 1701a: The awareness function network element sends an eighth request to the mobility management network element; correspondingly, the mobility management network element receives the eighth request from the awareness function network element.

[0459] The eighth request may be used to request identification information of an access network device to which the target object accesses, and the eighth request includes identification information of the target object.

[0460] Optionally, the perception function network element may obtain identification information of the target object from the application function network element or the mobility management network element.

[0461] The application function network element may send the identification information of the target object to the perception function network element. Alternatively, the application function network element may send the identification information of the target object to the network open network element. The network open network element determines the mobility management network element corresponding to the target object based on the identification information of the target object, and then sends the identification information of the target object to the mobility management network element. The mobility management network element then sends the identification information of the target object to the perception function network element.

[0462] The network open network element may query the UDM for the mobility management network element corresponding to the target object based on the identification information of the target object.

[0463] Optionally, the application function network element may carry the identification information of the target object in the ninth request and send it to the perception function network element, or may send the ninth request to the perception function network element through the network open network element and the mobility management network element.

[0464] The ninth request may be used to request obtaining the moving trajectory of the target object.

[0465] Optionally, the ninth request may further include one or more of the following: the first position of the target object, the start time of the perception measurement, the end time of the perception measurement, the preset movement trajectory of the target object, and characteristic information of the target object.

[0466] Step 1701b: The mobility management network element sends fifth indication information to the awareness function network element; correspondingly, the awareness function network element receives the fifth indication information from the mobility management network element.

[0467] The fifth indication information may include identification information of the first access network device. The first access network device may also be referred to as a first perception device.

[0468] Among them, the mobility management network element can determine the access network device accessed by the target object as the first access network device according to the received eighth request, and indicate it to the perception function network element through the fifth indication information.

[0469] Optionally, if the target object is currently in a radio resource control (RRC) idle state, the mobility management network element may page the target object so that the target object establishes an RRC connection with the access network device, and determines the access network device to which the target object accesses as the first access network device.

[0470] Step 1702: The first access network device sends a perception measurement result to the perception function network element; correspondingly, the perception function network element receives the perception measurement result from the first access network device.

[0471] The first access network device may perform perception measurement according to the first request sent by the perception function network element, obtain the perception measurement result and send it to the perception function network element.

[0472] Optionally, the perception function network element may further send second indication information to the first access network device, where the second indication information is used to instruct the first access network device to stop the perception measurement. The first access network device stops the perception measurement according to the second indication information.

[0473] Exemplarily, the perception function network element may send second indication information to the first access network device when the target object switches from the first access network device to another access network device (such as the second access network device described below).

[0474] In another example, the perception function network element may also send second indication information to the first access network device when it determines that the target object leaves the perception area of ​​the first access network device based on the perception measurement result of the first access network device and the perception area information of the first access network device.

[0475] In another example, the perception function network element can also predict the movement trajectory of the target object based on the perception measurement results of the first access network device. When it is determined according to the prediction results that the target object is about to leave the perception area of ​​the first access network device, the perception function network element can send a second indication information to the first access network device.

[0476] Step 1703: The mobility management network element sends sixth indication information to the awareness function network element; correspondingly, the awareness function network element receives the sixth indication information from the mobility management network element.

[0477] The sixth indication information may include identification information of a second access network device to which the target object is currently connected. The second access network device may also be referred to as a second sensing device.

[0478] Among them, the mobility management network element can indicate the second access network device to the perception function network element through sixth indication information when the target object switches from the first access network device to the second access network device based on the eighth request sent by the perception function network element.

[0479] Exemplarily, the perception function network element may send a subscription request (i.e., the eighth request) to the mobility management network element. The subscription request may be used to subscribe to the identification information of the target access network device of the target object. When the target object switches from the first access network device to the target access network device, the mobility management network element may send a subscription notification message to the perception function network element. The subscription notification message may include the identification information of the target access network device and the identification information of the target object. Based on the subscription notification message, the perception function network element determines the target access network device as the second access network device.

[0480] The eighth request may be used to request access to an access network device to which the target object has access, and the eighth request includes identification information of the target object.

[0481] Step 1704: The perception function network element sends a second request to the second access network device; correspondingly, the second access network device receives the second request from the perception function network element.

[0482] The second request may be used to request the second access network device to perform perception measurement.

[0483] Optionally, the second request sent by the perception function network element to the second access network device may include one or more of the following: identification information of the target object, characteristic information of the target object, the second location, the first indication information, and a preset movement trajectory of the target object. The first indication information is used to indicate activation of perception measurement in all perception areas of the perception device.

[0484] The perception function network element may carry the identification information and / or characteristic information and / or the second location of the target object in the second request sent to the second access network device, thereby instructing the second access network device to only perceive the target object, thereby reducing the power consumption caused by perception. Alternatively, the perception function network element may carry the first indication information in the second request sent to the second access network device, thereby instructing the second access network device to activate perception measurement in all perception areas of the second access network device, thereby improving the accuracy of the perception measurement results.

[0485] The description of the second position may refer to the description of the second position in FIG. 9 , and will not be repeated here.

[0486] Step 1705: The second access network device sends the perception measurement result to the perception function network element; correspondingly, the perception function network element receives the perception measurement result from the second access network device.

[0487] The second access network device may perform perception measurement according to the second request sent by the perception function network element, obtain the perception measurement result and send it to the perception function network element.

[0488] Optionally, the perception function network element may further send second indication information to the second access network device, where the second indication information is used to instruct the second access network device to stop the perception measurement. The second access network device stops the perception measurement according to the second indication information.

[0489] Exemplarily, the perception function network element may send second indication information to the second access network device when the target object is switched from the second access network device to another access network device.

[0490] In another example, the perception function network element may also send second indication information to the second access network device when it determines that the target object leaves the perception area of ​​the second access network device based on the perception measurement results of the second access network device and the perception area information of the second access network device.

[0491] In another example, the perception function network element can also predict the movement trajectory of the target object based on the perception measurement results of the second access network device. When it is determined according to the prediction results that the target object is about to leave the perception area of ​​the second access network device, the perception function network element can send a second indication information to the second access network device.

[0492] Based on the method shown in FIG17 above, the target object does not participate in the perception measurement process, and the target object may have identification information. The perception function network element can achieve continuous perception measurement of the target object based on the identification information of the target object with the help of communication capabilities. For example, an access network device that can provide a communication link (such as an access network device with a perception function, which can also be called a perception device) can be used for perception. When the target object switches the communication link, the switching of the access network device can be triggered, thereby ensuring that the target object is always within the perception area of ​​the access network device during the movement, achieving continuous perception of the target object, and ensuring the continuity of the perception service.

[0493] Based on the method in FIG17 , the perception function network element can also determine the target object's movement trajectory based on the perception measurement results of the first access network device and the second access network device. The perception function network element can also send the target object's movement trajectory to the application function network element. For details, please refer to the aforementioned description of the perception function network element determining the target object's movement trajectory based on the perception measurement results of the first access network device and the second access network device and sending it to the application function network element, and will not be repeated here.

[0494] Optionally, when the application function network element receives the moving trajectory of the target object sent by the perception function network element, it can also calibrate the moving trajectory of the target object based on one or more of the following: characteristic information of the target object, preset moving trajectory of the target object, and location information of the target object.

[0495] Based on the above description, the following takes the application function network element as AF, the perception function network element as SF, the mobility management network element as AMF, and the corresponding perception devices of the target object during movement as an example, and refers to the following Figure 18 to illustrate the perception measurement method shown in Figure 17.

[0500] Among them, SF can query UDM for the AMF that serves the target object, thereby obtaining the identification information of the AMF.

[0501] Step 1803: SF queries AMF for the identification information of the access network device where the target object is currently located; accordingly, SF receives the identification information of the access network device from AMF.

[0502] Among them, if the target object is in the RRC idle state, the AMF can page the target object to establish an RRC connection between the target object and the access network device, and then send the identification information of the access network device to the SF.

[0503] Step 1804: SF sends a perception measurement request to access network device 1; correspondingly, access network device 1 receives the perception measurement request from SF.

[0520] Step 1812: SF aggregates the sensing measurement results to generate a moving trajectory of the target object.

[0521] Step 1813: The SF sends a sensing service response to the AF; correspondingly, the AF receives the sensing service response from the SF.

[0522] The perception service response includes the target object's movement trajectory. The perception service response can refer to the aforementioned description of the third response and is not repeated here. Steps 1812 and 1813 can also refer to the aforementioned description of the perception function network element sending the target object's movement trajectory to the application function network element and are not repeated here.

[0523] Different from the above-mentioned FIG18 where the AF sends a perception service request to the SF, as shown in FIG19 , the AF can also send a perception service request to the SF through the AMF.

[0524] FIG19 is a flowchart of a perception measurement method provided in an embodiment of the present application. As shown in FIG19 , the perception measurement method may include:

[0552] Based on the description of Figures 17 to 19 above, the perception function network element may optionally send a tenth request to the mobility management network element when determining that a breakpoint occurs in the target object's movement trajectory. The tenth request may be used to request the target object's location information. The mobility management network element obtains the target object's location information based on the tenth request and sends a tenth response to the perception function network element. The perception function network element calibrates the movement trajectory based on the received location information.

[0553] Optionally, if the target object is in an RRC idle state, the mobility management network element may page the target object to obtain the location information of the target object.

[0561] Step 2003: SF queries AMF for the identification information of the access network device where the target object is currently located; accordingly, SF receives the identification information of the access network device from AMF.

[0562] Among them, if the target object is in the RRC idle state, the AMF can page the target object to establish an RRC connection between the target object and the access network device, and then send the identification information of the access network device to the SF.

[0563] Step 2004: SF sends a perception measurement request to access network device 1; correspondingly, access network device 1 receives the perception measurement request from SF.

[0568] Optionally, the above steps 2001 to 2006 may also be replaced by the above steps 1901 to 1907 without limitation.

[0569] Step 2007: When the SF determines that a breakpoint occurs in the moving trajectory of the target object based on the perception measurement results, the AMF triggers the positioning process of the target object.

[0570] Step 2008: AMF requests LMF to locate the target object.

[0571] Among them, if the target object is in the RRC idle state, the AMF can page the target object to establish an RRC connection between the target object and the access network device, and then the LMF can locate the target object.

[0572] Step 2009: LMF sends the location information of the target object to SF.

[0573] Among them, LMF can send the location information of the target object directly to SF, or send the location information of the target object to SF through AMF, without restriction.

[0574] Step 2010: SF calibrates the movement trajectory according to the position information of the target object.

[0575] Optionally, after SF calibrates the movement trajectory, it may continue to perform perception measurement on the target object by referring to the following steps 2011 to 2017:

[0576] Step 2011: SF sends a subscription request to AMF; correspondingly, AMF receives the subscription request from SF.

[0577] The subscription request may be used to subscribe to identification information of a target access network device of a target object.

[0584] Step 2014: Access network device 2 performs perception measurement.

[0585] Step 2015: Access network device 2 reports the perception measurement result to SF; correspondingly, SF receives the perception measurement result from access network device 2.

[0586] Step 2016: SF aggregates the perception measurement results to generate the movement trajectory of the target object.
