[0072] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0073] Figure 1 A schematic diagram of an application scenario of an open method for perceiving information provided in an embodiment of the present application. Figure 1 As shown, in this scenario, there are a sensing function SF (Sensing Function) network element 102, an application function AF (Application Function) network element 104, a sensing device (base station (Radio Access Network) or user terminal UE (User Equipment)) 106 and a network exposure function NEF (Network Exposure Function) network element 108. The sensing function SF network element 102 is connected to the application function AF network element 104, the sensing device 106 and the network exposure function NEF network element 108 respectively.

[0074] Among them, the perception function SF network element 102 can be implemented based on the location management function LMF (Location Management Function) network element in the 5G network. For example, a module for perception function management, perception data processing, and perception result opening can be added to the location management function LMF network element to transform it into the perception function SF network element 102, and the original 5GC interface of the location management function LMF network element is used to transmit the perception data. In this way, there is no need to add a new interface in the 5G core network to process the perception data, which can save 5GC interface resources.

[0075] The application function AF network element 104 needs to be connected to the network open function NEF network element 108 to access the 5G core network through the network open function NEF network element 108; or when the application function AF network element 104 is trustworthy, it can directly interact with other network elements (such as SF network elements) and provide business services.

[0076] In one embodiment, Figure 2 As shown, an open method for perceiving information is provided. In this embodiment, the method is applied to Figure 1 The sensing function SF network element 102 in the embodiment of the present invention is described, and the following steps are included:

[0077] Step 202: Receive a perception information acquisition request sent by an application function AF network element, and determine a perception device according to the perception information acquisition request, where the perception device is a base station and / or a user terminal UE.

[0078] In an embodiment of the present application, when the application function AF network element needs to initiate a perception service to the 5G network and obtain perception data, it can send a perception information acquisition request to the perception function SF network element. The perception information acquisition request may include the type of perception service that the application function AF network element needs to perform. The perception function SF network element can obtain the capability information of each perception device. After receiving the perception information acquisition request, the perception function SF network element can determine the perception device that can perform the perception service type based on the perception service type specified in the perception information acquisition request and the capability information of each perception device. For example, if the perception service type is vehicle tracking, then an on-board terminal or a nearby base station can be selected as a perception device; if the perception service type is track safety monitoring, then a monitoring terminal or base station near the track can be selected as a perception device. This embodiment of the present application does not specifically limit this.

[0079] The perception information acquisition request of the application function AF network element can also be forwarded by the access and mobility management function AMF (Access and Mobility Management Function) network element. That is, since there may be multiple perception function SF network elements, the perception function SF network element can first send a perception information acquisition request to the authentication management function AMF network element, and the authentication management function AMF network element selects a perception function SF network element that is most suitable for executing the perception service type from multiple perception function SF network elements according to the perception service type, and forwards the perception information acquisition request to the perception function SF network element. The perception function SF network element then determines the perception device according to the perception information acquisition request, and executes the subsequent process of returning the obtained perception results to the application function AF network element.

[0080] Step 204: Send a perception measurement request to the perception device, so that the perception device collects perception data according to the perception measurement request.

[0081] In the embodiment of the present application, the perception function SF network element can generate a perception measurement request based on the received perception information acquisition request, and send the perception measurement request to the corresponding perception device. After receiving the perception measurement request, the perception device collects perception data and returns the perception data to the perception function SF network element after the collection is completed.

[0082] The perception measurement request may also include the perception service type, so that the perception device can collect the data required by the perception service type in a targeted manner. Alternatively, the perception device may return all the collected data to the perception function SF network element, and the perception function SF network element may filter out the data corresponding to the perception service type, which is not specifically limited in the embodiments of the present application.

[0083] Step 206: Receive the perception data sent by the perception device and determine the perception result according to the perception data.

[0084] In the embodiment of the present application, the perception result is the result obtained by processing the perception data. For example, if the perception data sent to the perception function network element SF is point cloud data, the perception result can be the recognition result obtained by processing the point cloud data. After receiving the perception data, the perception function SF network element can process the perception data according to the perception service type in the perception information acquisition request to obtain the perception result, and then send the perception result to the application function AF network element.

[0085] Step 208: Send the sensing result to the network open function NEF network element, so that the network open function NEF network element sends the sensing result to the application function AF network element.

[0086] In the embodiment of the present application, the perception function SF network element can send the perception result to the application function AF network element through the network open function NEF network element. The perception function SF network element can first send the perception result to the network open function NEF network element, and then the network open function NEF network element sends the perception result to the application function AF network element. The network open function NEF network element can also open the perception result to other network elements in the network, which is not specifically limited in the embodiment of the present application.

[0087] The method for opening perception information provided in the embodiment of the present application sets a perception function SF network element in the existing 5G network service architecture, so that the perception function SF network element can receive the perception information acquisition request sent by the application function AF network element, and select the perception device to collect perception data according to the perception information acquisition request, and then process the perception data. After obtaining the perception result, the perception result is returned to the application function AF network element through the network opening function NEF network element.

[0088] In one embodiment, the perception information acquisition request includes the perception service type, perception service requirements, target perception area or target perception object, and perception capability information of each candidate perception device. The candidate perception device is a perception device that can perceive the target perception area or target perception object.

[0089] In an embodiment of the present application, the perception information acquisition request may carry the perception service type, perception service requirements (specific requirements for the perception service type, such as perception duration, perception resolution (sampling rate)), target perception area (specific area where perception service is required), target perception object (specific object that needs to be perceived, such as drones, etc.) and perception capability information of each candidate perception device that can perceive the target perception area or target perception object (that is, whether each candidate perception device can perceive the target perception area or target perception object, what type of perception data can be collected, etc.).

[0090] The perception capability information of the perception device can be uploaded by each perception device when registering with the 5G network and opened to the application function AF network element. When the application function AF network element needs to obtain the perception information of a target perception area or a target perception object, it first determines whether it needs to perceive the target perception area or the target perception object, and then generates a perception information acquisition request based on the perception service type, perception service requirements and the perception capability information of each candidate perception device; or, the perception capability information can also be stored on a network node in the 5G network. When the candidate perception device needs to obtain the perception capability information of the candidate perception device that can perceive the target perception area or the target perception object, it sends a perception capability information acquisition request to the network node based on the need to perceive the target perception area or the target perception object, and then the network node determines the candidate perception device and the perception capability information of the candidate perception device based on the perception capability information acquisition request, and returns the perception capability information of the candidate perception device to the application function AF network element, and the application function AF network element then generates a perception information acquisition request based on the perception capability information. Other methods can also be used to enable the application function AF network element to obtain the perception capability information of the candidate perception device, and the embodiments of the present application do not specifically limit this.

[0091] The open method of perception information provided in the embodiment of the present application includes the perception service type, perception service requirements, target perception area or target perception object, and perception capability information of each candidate perception device in the perception information acquisition request, so that the perception function SF network element can select the perception device according to the above information, and the perception device can collect perception data according to the above information, and the perception function SF network element can obtain the perception result according to the above information processing, so that the application function AF network element can obtain the perception result that better meets its requirements.

[0092] In one embodiment, determining a sensing device according to a sensing information acquisition request includes:

[0093] A sensing device is determined from the candidate sensing devices according to the sensing capability information of each candidate sensing device.

[0094] In the embodiment of the present application, the perception function SF network element can determine the perception device used when collecting perception data according to the perception capability information of each candidate perception device. For example, the perception function SF network element can determine the target perception device whose perception capability information meets the perception service type and perception service requirements from the candidate perception devices according to the perception service type and perception service requirements, and then further screen the perception devices from the target perception devices to obtain the perception devices that are finally used to collect perception data.

[0095] Taking the case where the type of perception service is vehicle tracking, and the perception data that needs to be reported to the perception function network element SF is point cloud data, that is, the perception device whose perception capability information satisfies the type of perception service is a base station that can collect raw data and send point cloud data to the core network, the perception function SF network element can screen out target perception base stations that can collect raw data and generate point cloud data from each candidate perception base station according to the perception capability information of each candidate perception base station, and then determine the perception device from each target perception base station. For example, the perception function SF network element can give priority to selecting an idle target perception base station as a perception device, or it can also select a target perception base station with the best quality of collected perception data as a perception device. Other methods can also be used to determine the perception device, and the embodiments of the present application do not specifically limit this.

[0096] The open method for perception information provided in the embodiment of the present application obtains the perception device based on the perception capability information, and can select the perception device whose perception capability information meets the requirements of the perception service type from various candidate perception devices as the final perception device, so that the application function AF network element can obtain perception results that better meet its requirements.

[0097] In one embodiment, receiving the sensing data sent by the sensing device includes:

[0098] Receive the perception data sent by the user plane function UPF network element. The perception data is sent by the perception device to the user plane function UPF network element, and then forwarded by the user plane function UPF network element to the perception function SF network element.

[0099] In the embodiment of the present application, the perception device can upload the perception data through the user plane of the 5G network. The perception device can be connected to the user plane function UPF network element, and after collecting the perception data, the perception data is sent to the user plane function UPF network element, and the user plane function UPF network element then forwards the perception data to the perception function network element.

[0100] The open method of perception information provided in the embodiment of the present application uploads the perception data to the perception function SF network element through the user plane function UPF network element, and can use the original user plane transmission path in the 5G network to transmit the perception data to the perception function SF network element, which can save 5GC interface resources.

[0101] In one embodiment, receiving the sensing data sent by the sensing device includes:

[0102] Receive the perception data sent by the access and mobility management function AMF network element. The perception data is sent by the perception device to the access and mobility management function AMF network element, and forwarded by the access and mobility management function AMF network element to the perception function SF network element.

[0103] In the embodiment of the present application, the perception device can upload the perception data through the control plane of the 5G network. The perception device can be connected to the access and mobility management function AMF network element, and after collecting the perception data, the perception data is sent to the access and mobility management function AMF network element, and the access and mobility management function AMF network element then forwards the perception data to the perception function network element.

[0104] The open method of perception information provided in the embodiment of the present application uploads the perception data to the perception function SF network element through the access and mobility management function AMF network element, and can use the original control plane transmission path in the 5G network to transmit the perception data to the perception function SF network element, thereby saving 5GC interface resources.

[0105] In an embodiment, the perception information acquisition request also includes a perception data type, and the perception data type includes 3GPP perception data and / or non-3GPP perception data.

[0106] In the embodiment of the present application, the application function AF network element may also specify the type of perception data it needs in the perception information acquisition request. The perception data type may include 3GPP (3 rdThe 3GPP perception data refers to data collected by wireless signals that comply with the 3GPP standard, such as terrain data in the surrounding environment, rainfall monitoring data, etc.; non-3GPP perception data refers to data collected by other sensors that do not comply with the 3GPP standard, such as video data, lidar data, or sonar data. The perception function SF network element can generate perception results based on different types of perception data. For example, if the type of perception data is 3GPP data, the perception function SF network element can use data collected by a device (such as a base station) that can transmit wireless signals that comply with the 3GPP standard to calculate the perception results; if the type of perception data is non-3GPP data, the perception function SF network element can use data collected by other sensors that do not comply with the 3GPP standard to calculate the perception results.

[0107] The method for opening perception information provided in the embodiment of the present application can enable the application function AF network element to specify whether it needs 3GPP perception data or non-3GPP perception data in the perception information acquisition request, so that the application function AF network element can obtain perception results that better meet its requirements.

[0108] In one embodiment, Figure 3 As shown, an open method for perceiving information is provided. In this embodiment, the method is applied to Figure 1 The sensing device 106 in the embodiment of the present invention is described, and the following steps are included:

[0109] Step 302: receiving a perception measurement request, wherein the perception measurement request is sent by the perception function SF network element after receiving the perception information acquisition request, and the perception information acquisition request is sent by the application function AF network element to the perception function SF network element.

[0110] In the embodiment of the present application, when the application function AF network element needs to obtain the perception data, it sends a perception information acquisition request to the perception function SF network element. After receiving the perception information acquisition request, the perception function SF network element further sends a perception measurement request to the perception device. The perception device can then collect the perception data according to the perception measurement request.

[0111] Step 304, in response to the perception measurement request, collect perception data, and send the perception data to the perception function SF network element, so that the perception function SF network element determines the perception result based on the perception data, sends the perception result to the network open function NEF network element, and enables the network open function NEF network element to send the perception data to the application function AF network element.

[0112] In the embodiment of the present application, after receiving the perception measurement request, the perception device collects the perception data according to the perception measurement request, and then returns the perception data to the perception function SF network element. The perception function SF network element then calculates the perception result based on the perception data, sends the perception result to the network open function NEF network element, and the network open function NEF network element opens the perception result to the application function AF network element. Among them, the interaction process between the network elements can refer to the relevant description in the above embodiment, and the embodiment of the present application will not be repeated here.

[0113] The method for opening perception information provided in the embodiment of the present application sets a perception function SF network element in the existing 5G network service architecture, so that the perception function SF network element can receive the perception information acquisition request sent by the application function AF network element, and select the perception device to collect perception data according to the perception information acquisition request, and then process the perception data. After obtaining the perception result, the perception result is returned to the application function AF network element through the network opening function NEF network element.

[0114] In one embodiment, Figure 4 As shown, in the case where the sensing device is a user terminal UE, in step 304, the sensing data is sent to the sensing function SF network element, including:

[0115] Step 402: Send the perception data to the first target base station, so that the first target base station sends the perception data to the perception function SF network element.

[0116] Step 404, collects the base station information of each candidate base station, and sends the base station information to the first target base station, so that the first target base station determines the second target base station from each candidate base station according to the base station information, and starts the base station switching process when the second target base station meets the base station switching conditions, so that the sensing device switches to connect with the second target base station.

[0117] In an embodiment of the present application, when the perception device is a user terminal UE, the perception device needs to upload the perception data to the perception function SF network element through the first target base station currently connected to it. In order to ensure that the perception device can successfully upload perception data even when moving, the perception device can collect base station information of surrounding candidate base stations while collecting perception data (the candidate base station can be other base stations that can currently be connected to the perception device except the first target base station), and send the base station information to the first target base station, so that the first target base station decides whether it is necessary to switch the perception device to connect to one of the candidate base stations. The perception device can collect base station information once at a fixed interval, or it can collect base station information once after each perception data is collected and uploaded to the perception function SF network element. The embodiment of the present application does not specifically limit this.

[0118] The base station information may include information such as the signal strength of each candidate base station, the transmission power of each candidate base station, and the distance between each candidate base station and the sensing device. The first target base station can select an optimal base station as the second target base station (for example, a candidate base station with the best signal strength, a base station with a distance from the sensing device within a certain distance interval, and a base station with the best signal strength, etc.) according to the base station information of each candidate base station. The base station switching condition is a preset condition and is related to the base station information. For example, the base station switching condition can be set to that the signal strength of the second target base station is better than that of the current first target base station; or it can also be set to that the signal strength of the second target base station is better than that of the current first target base station, and the second target base station is located in the moving direction of the sensing device, etc. When the second target base station meets the base station switching condition, the first target base station can start the base station switching process and switch the sensing device to connect with the second target base station. The first target base station can also send the sensing measurement information (such as the type of sensing data, etc.) related to the sensing device collecting sensing data to the second target base station. Among them, the base station switching process can refer to the existing process of switching base stations of terminal devices, and the embodiments of the present application will not be repeated here.

[0119] Reference Figure 5 , Figure 6 As shown, the process of the perception device switching to the second target base station when the perception data is transmitted through the user plane, and the process of the perception device switching to the second target base station when the perception data is transmitted through the control plane. In the case where the perception data is transmitted through the user plane, the perception device needs to upload the perception data to the first target base station connected to it, and then the first target base station sends the perception data to the user plane function UPF network element; after the perception device switches to connect with the second target base station, the perception device needs to upload the perception data to the second target base station, and then the second target base station sends the perception data to the user plane function UPF network element. Similarly, in the case where the perception data is transmitted through the control plane, when the perception device is connected to the first target base station, the perception data is sent to the access and mobility management function AMF network element through the first target base station; after the perception device switches to connect with the second target base station, the perception device will send the perception data to the access and mobility management function AMF network element through the second target base station.

[0120] The open method of perception information provided in the embodiment of the present application enables the perception device to upload perception data to the perception function SF network element through the base station when the perception device is a user terminal UE, and enables the perception device to collect base station information in the process, so that when there is a second target base station that is better than the first target base station currently connected to the perception device, the perception device can switch to connect with the second target base station, thereby avoiding the situation where the perception device cannot upload perception data in time due to poor base station signal during movement, thereby improving the reliability of the perception device in collecting perception data.

[0121] In one embodiment, an open system for sensing information is provided. Figure 1 As shown, the system includes a sensing device 106, an application function AF network element 104, a sensing function SF network element 102 and a network open function NEF network element 108, wherein the sensing device is a base station and / or a user terminal UE, wherein the application function AF network element 104 is used to send a sensing information acquisition request to the sensing function SF network element 102. The sensing function SF network element 102 is used to determine the sensing device 106 according to the sensing information acquisition request, and send a sensing measurement request to the sensing device 106. The sensing device 106 is used to collect sensing data according to the sensing measurement request, and send the sensing data to the sensing function SF network element 102. The sensing function SF network element 102 is also used to receive the sensing data sent by the sensing device 106, determine the sensing result according to the sensing data, and send the sensing data to the network open function NEF network element 108. The network open function NEF network element 108 is used to send the sensing data to the application function AF network element 104.

[0122] In the embodiment of the present application, when the application function AF network element 104 needs to obtain the perception data, it sends a perception information acquisition request to the perception function SF network element 102. After receiving the perception information acquisition request, the perception function SF network element 102 determines the perception device 106 for collecting the perception data required for the perception information acquisition request, and sends a perception measurement request to the perception device 106. The perception device 106 can then collect the perception data according to the perception measurement request, and then return the perception data to the perception function SF network element 102. The perception function SF network element 102 then calculates the perception result based on the perception data, sends the perception result to the network open function NEF network element 108, and the network open function NEF network element 108 opens the perception result to the application function AF network element 104.

[0123] Among them, the interaction process between the network elements can refer to the relevant description in the aforementioned embodiment, and the embodiments of the present application will not be repeated here.

[0124] The open system for perception information provided in the embodiment of the present application sets a perception function SF network element in the existing 5G network service architecture, so that the perception function SF network element can receive the perception information acquisition request sent by the application function AF network element, and select the perception device to collect the perception data according to the perception information acquisition request, and then process the perception data. After obtaining the perception result, the perception result is returned to the application function AF network element through the network open function NEF network element.

[0125] In one embodiment, referring to Figure 7 As shown, the above system also includes an access and mobility management function AMF network element 110, a mobile positioning center gateway GMLC (Gateway Mobile Location Center) 112 and a unified data management UDM (Unified Data Management) network element 114, and the application function AF network element 104 is also used to send a perception information acquisition request to the mobile positioning center gateway GMLC 112 through the network open function NEF network element 108. The mobile positioning center gateway GMLC 112 is used to send an authority verification request to the unified data management UDM network element 114 based on the perception information acquisition request. The unified data management UDM network element 114 is used to perform authority verification on the perception information acquisition request based on the authority verification request, and send the address of the access and mobility management function AMF network element 110 to the mobile positioning center gateway GMLC 112 if the authority verification passes. The mobile positioning center gateway GMLC 112 is also used to forward the perception information acquisition request to the access and mobility management function AMF network element 110 according to the address of the access and mobility management function AMF network element 110. The access and mobility management function AMF network element 104 is used to forward the perception information acquisition request to the perception function SF network element 102.

[0126] In the embodiment of the present application, when the perception function network element SF is set by adding a module for perception function control, perception data processing, and perception result opening in the positioning management function network element LMF, refer to Figure 8As shown, the application function AF network element 104 needs to access the 5G network through the mobile positioning center gateway GMLC 112, and needs to perform permission verification through the unified data management UDM network element 114. The application function AF network element 104 can first send a perception information acquisition request to the mobile positioning center gateway GMLC 112 (which can be sent through the network open function NEF network element 108), and then the mobile positioning center gateway GMLC 112 sends a permission verification request to the unified data management UDM network element 114 based on the perception information acquisition request to determine whether the application function AF network element 104 has the permission to obtain the perception data it requires. The unified data management UDM network element 114 verifies the permission of the perception information acquisition request, and if the permission verification fails, it sends a response message to the mobile positioning center gateway GMLC 112 to refuse the application function AF network element 104 to obtain the perception data it requires. Or if the authority verification is passed, the address of the access and mobility management function AMF network element 110 of the current service is sent to the mobile positioning center gateway GMLC 112, so that the mobile positioning center gateway GMLC 112 can forward the perception information acquisition request to the access and mobility management function AMF network element 104 according to the address of the access and mobility management function AMF network element 110, and the access and mobility management function AMF network element 104 then forwards the perception information acquisition request to the perception function SF network element 102.

[0127] The open system of perception information provided in the embodiment of the present application enables the perception information acquisition request initiated by the application function AF network element to undergo authority verification before being sent to the 5G core network, which can prevent the application function AF network element with insufficient authority from obtaining perception data and ensure the security of the perception data.

The access and mobility management function AMF network element 110 is also used to forward the perception information acquisition request to the perception function SF network element 102 corresponding to the target perception area or target perception object according to the need to perceive the target perception area or target perception object. The perception function SF network element 102 is also used to determine the perception device 106 from each candidate perception device according to the perception capability information of each candidate perception device.

[0129] In the embodiment of the present application, the perception information acquisition request may include the area (target perception area) for which the application function AF network element 104 needs to obtain perception data or the object (target perception object) for which the perception data needs to be obtained, and the perception capability information of each candidate perception device that can perceive the target perception area or the target perception object. The perception capability information can be specifically referred to the relevant description of the aforementioned embodiment, and the embodiment of the present application will not be repeated here.

[0130] Multiple perception function SF network elements 102 may exist simultaneously in the 5G network, and each perception function SF network element 102 is responsible for processing the perception data of an area. The access and mobility management function AMF network element 110 can obtain the perception function SF network element 102 corresponding to the target perception area or the target perception object according to the need to perceive the target perception area or the target perception object, and forward the perception information acquisition request to the perception function SF network element 102. The perception function SF network element 102 can then determine the perception device 106 from the candidate perception devices based on the perception capability information of each candidate perception device that can perceive the target perception area or the target perception object. The process of the perception function SF network element 102 determining the perception device 106 can also be referred to the relevant description in the aforementioned embodiment, and the embodiments of the present application will not be repeated here.

[0131] The open system of perception information provided in the embodiment of the present application obtains perception devices based on perception capability information, and can select a perception device whose perception capability information meets the requirements of the perception service type from various candidate perception devices as the final perception device, thereby enabling the application function AF network element to obtain perception results that better meet its requirements.
