[0003] When network devices or terminal devices have the perception capabilities brought by wireless frequency bands (such as millimeter wave bands, terahertz bands, etc.), wireless communication systems can perceive and identify specific areas / objects / events / environments, etc.

[0004] Based on the service requester's perception service request, the core network device selects an appropriate perception device (such as a base station and / or terminal device) and sends perception control information to the selected perception device. The selected perception device executes the perception service based on the perception control information, obtains perception data, and reports the perception data to the core network device. The core network device can then share the perception results generated based on the perception data with the service requester, who can then apply the perception results to related applications.

[0005] Among them, how the perception device reports the perception data to the core network equipment is a problem that needs to be solved. Summary of the Invention

[0006] The embodiments of the present application provide a communication method and device that can improve perception efficiency.

[0007] In a first aspect, embodiments of the present application provide a communication method that can be performed by a perception function network element. The perception function network element herein may refer to the perception function network element itself, or to a processor, module, chip, or chip system within the perception function network element that implements the method. In this method, the perception function network element determines a perception data type based on perception information and sends information indicating the perception data type to a first perception device. The perception function network element receives perception data of the perception data type from the first perception device.

[0008] In the embodiment of the present application, the perception function network element sends the perception data type to the first perception device, which facilitates the first perception device to send perception data of the perception data type to the perception function network element, thereby improving perception efficiency. In addition, the perception data type is determined by the perception function network element based on the perception information, which facilitates matching the perception data received by the perception function network element with the differentiated requirements of the perception information.

[0009] In an optional embodiment, the perception information includes at least one of the following: the type of perception service, the perception principle, the perception performance indicator requirements, the data fusion effect indicator requirements, the security and privacy requirements, the operator's policy, the perception mode, the perception device type, the type of perception data supported by the perception device, or the processing capability of the service requester. This approach enables the perception function network element to determine the type of perception data based on the differentiated requirements for perception data such as relevant information of the perception service, thereby facilitating the perception data obtained by the perception function network element to meet the requirements of the perception service and improving perception efficiency.

[0010] In an optional implementation, the perception function network element determines the perception data type based on the perception information, including: determining a first perception result type open to the service requester based on the perception information and the authorization information of the service requester, the authorization information of the service requester includes the perception result type authorized by the service requester; and determining the perception data type based on the first perception result type.

[0011] In another optional implementation, the perception function network element determines the perception data type based on the perception information, including: determining a first perception result type open to the service requester based on the perception information; and determining the perception data type based on the first perception result type.

[0012] The way in which the perception function network element determines the type of perception data based on the determined first perception result type is conducive to the perception function network element determining the perception result of the first perception result type open to the service requester based on the obtained perception data.

[0013] In an optional implementation, the perception function network element sends information indicating the first perception result type to the service requester, so that the service requester knows that the perception function network element can open the perception result of the first perception result type to the service requester.

[0014] In an optional embodiment, the perception function network element receives information indicating a second perception result type from a service requester, where the second perception result type is used to indicate the perception result requested by the service requester. Thus, the perception function network element sends information indicating the first perception result type to the service requester, including: when the second perception result type is different from the first perception result type, sending information indicating the first perception result type to the service requester.

[0015] As can be seen, the service requester requests the perception function network element to open the perception result of the second perception result type. When the second perception result type is different from the first perception result type, the perception function network element indicates the first perception result type to the service requester. This method allows the service requester to know that the perception function network element cannot open the requested perception result to the service requester and can open the perception result of the first perception result type.

[0016] In an optional implementation, the perception function network element sends a perception result of the first perception result type to the service requester based on the perception data. This approach facilitates the service requester to perform perception identification based on the perception result.

[0017] In one optional embodiment, the sensing function network element determines a sensing principle based on the sensing service type and sensing performance indicator requirements, and sends information indicating the sensing principle to the first sensing device and / or the second sensing device. The sensing principle is either a radar sensing principle or a non-radar sensing principle. This approach facilitates the first sensing device and / or the second sensing device to perform sensing services based on the sensing principle indicated by the sensing function network element, thereby improving sensing efficiency.

[0018] Radar sensing processes the reflected signals from objects received by a receiver to obtain object or event characteristics. Non-radar sensing measures changes in wireless channel state information to obtain object or event characteristics. Alternatively, it can be achieved through cameras, ultrasound, or thermal imaging.

[0019] In one optional embodiment, the perception function network element sends information indicating an intermediate data type to the second perception device. The intermediate data type is used by the second perception device to determine intermediate data to be sent to the first perception device, and the intermediate data is used by the first perception device to obtain perception data. This approach facilitates the second perception device to determine intermediate data of the intermediate data type and send the intermediate data to the first perception device, thereby facilitating the first perception device to obtain perception data of the perception data type based on the intermediate data.

[0020] In one optional embodiment, the type of sensing data is one of raw data, spectral information, point cloud information, non-point cloud information, and sensing results. The raw data, spectral information, point cloud information, and sensing results are obtained when the first sensing device or the second sensing device performs sensing using radar sensing principles. The non-point cloud information is obtained when the first sensing device or the second sensing device performs sensing using non-radar sensing principles.

[0021] Specifically, the original data is obtained by processing the received reflected signal when the first sensing device or the second sensing device adopts the radar sensing principle to perform perception; the spectral information is obtained by processing the obtained original data when the first sensing device or the second sensing device adopts the radar sensing principle to perform perception; the point cloud information is obtained by processing the obtained spectral information when the first sensing device or the second sensing device adopts the radar sensing principle to perform perception; the perception result is obtained by processing the obtained point cloud information when the first sensing device or the second sensing device adopts the radar sensing principle to perform perception.

[0022] Among them, when the perception data type is raw data, or spectral information, or point cloud information, the perception function network element obtains perception data of the perception data type, which can enrich the type of perception results opened by the perception function network element to the service requester.

[0023] In an optional embodiment, the perception function network element sends information indicating the type of perception data to the first perception device, including: receiving a perception service request from a service requester; and sending information indicating the type of perception data to the first perception device based on the perception service request. It can be seen that the perception function network element receives the perception service request from the service requester, determines the first perception device based on the perception service request, and sends information indicating the type of perception data to the first perception device, so that the first perception device reports perception data of the perception data type to the perception function network element.

[0024] In an optional embodiment, the sensing function network element sends information indicating a type of sensing data to a first sensing device based on a sensing service request, including: determining the first sensing device based on a sensing area in the sensing service request, where the first sensing device is a sensing device within the sensing area; and sending information indicating the type of sensing data to the first sensing device. It can be seen that the sensing service request includes the sensing area, and the sensing function network element determines the first sensing device within the sensing area as the sensing device that performs the sensing service, thereby sending information indicating the type of sensing data to the first sensing device.

[0025] In an optional embodiment, the perception function network element determines a first perception device based on the perception area in the perception service request, including: determining one or more perception devices based on the perception area in the perception service request; determining a first perception device based on the perception data type supported by one or more perception devices, and the first perception device supports the perception data type determined by the perception function network element.

[0026] As can be seen, before the perception function network element sends information indicating the type of perception data to the first perception device, it determines one or more perception devices located within the perception area, and then determines the first perception device among the one or more perception devices that supports the determined type of perception data as the perception device that performs the perception service. Thus, the perception function network element sends information indicating the type of perception data to the first perception device to obtain perception data of the type of perception data.

[0032] In an optional implementation, the non-point cloud information includes channel state information corresponding to the sensing area, and the channel state information includes at least one of the received power, received quality, channel quality, or delay of the multipath signal.

[0033] In a second aspect, embodiments of the present application provide a communication method that can be performed by a first sensing device. The first sensing device herein may refer to the first sensing device itself, or to a processor, module, chip, or chip system within the first sensing device that implements the method. In this method, the first sensing device receives information indicating a type of sensing data from a sensing function network element and transmits sensing data of the sensing data type to the sensing function network element. The sensing data type is determined based on the sensing information.

[0034] In the embodiment of the present application, the first sensing device receives a sensing data type indicated by the sensing function network element, and then sends sensing data of the sensing data type to the sensing function network element, thereby improving sensing efficiency. In addition, the sensing data type is determined by the sensing function network element based on the sensing information, which helps the sensing data received by the sensing function network element match the differentiated requirements of the sensing information.

[0035] In an optional embodiment, the perception information includes at least one of the following: the type of perception service, the perception principle, the perception performance indicator requirements, the data fusion effect indicator requirements, the security and privacy requirements, the operator's policy, the perception mode, the type of perception device, the type of perception data supported by the perception device, or the processing capability of the service requester. This approach facilitates the perception function network element to determine the type of perception data based on the differentiated requirements for perception data such as the perception service, thereby facilitating the obtained perception data to meet the requirements of the perception service and improving perception efficiency.

[0036] In one optional embodiment, before sending perception data of the perception data type to the perception function network element, the first perception device further performs the following steps: receiving information from the perception function network element indicating a perception principle, where the perception principle is a radar perception principle or a non-radar perception principle, and the perception principle is determined based on the perception service type and perception performance indicator requirements; and performing a perception service based on the perception principle to obtain perception data of the perception data type. This indicates that the first perception device performs perception based on the perception principle indicated by the perception function network element to obtain perception data of the perception data type, thereby improving perception efficiency.

[0037] Radar sensing processes the reflected signals from objects received by a receiver to obtain object or event characteristics. Non-radar sensing measures changes in wireless channel state information to obtain object or event characteristics. Alternatively, it can be achieved through cameras, ultrasound, or thermal imaging.

[0038] In an optional implementation, before the first perception device sends perception data of the perception data type to the perception function network element, it also performs: receiving intermediate data of the intermediate data type from the second perception device; and obtaining perception data of the perception data type based on the intermediate data.

[0039] It can be seen that when the first sensing device is not a sensing device that receives the reflected signal, the sensing data of the sensing data type can be obtained based on the intermediate data from the second sensing device.

[0040] In one optional embodiment, the type of perception data is one of raw data, spectral information, point cloud information, non-point cloud information, and perception results. The raw data, spectral information, point cloud information, and perception results are obtained when the first or second perception device performs perception using radar perception principles.

[0049] In a third aspect, embodiments of the present application provide a communication method that can be performed by a second sensing device. The second sensing device herein can refer to either the second sensing device itself or a processor, module, chip, or chip system within the second sensing device that implements the method. In this method, the second sensing device receives information indicating an intermediate data type. The intermediate data type is used by the second sensing device to determine intermediate data to send to a first sensing device, and the intermediate data is used by the first sensing device to obtain sensing data. The second sensing device then sends the intermediate data to the first sensing device. The intermediate data is determined by the second sensing device based on the intermediate data type.

[0050] In an embodiment of the present application, the second perception device receives information indicating the intermediate data type, thereby sending intermediate data determined based on the intermediate data type to the first perception device, which is beneficial for the first perception device to obtain perception data reported to the perception function network element based on the intermediate data.

[0051] In an optional embodiment, the second perception device receives information indicating the intermediate data type, including: receiving information indicating the intermediate data type from the perception function network element or the first perception device. It can be seen that the information indicating the intermediate data type can be sent from the perception function network element to the second perception device, or from the first perception device to the second perception device.

[0052] In an optional embodiment, the second sensing device further receives information from the sensing function network element indicating a sensing principle. The radar sensing principle involves processing the object reflection signal received by the receiver to obtain object characteristic information or event characteristic information. The non-radar sensing principle involves measuring changes in wireless channel state information to obtain object characteristic information or event characteristic information; or obtaining object characteristic information or event characteristic information through a camera; or obtaining object characteristic information or event characteristic information through ultrasound; or obtaining object characteristic information or event characteristic information through thermal imaging.

[0053] In one optional embodiment, the intermediate data type is one of raw data, spectral information, point cloud information, or non-point cloud information. The raw data, spectral information, and point cloud information are obtained when the first or second sensing device performs perception using radar sensing principles, while the non-point cloud information is obtained when the first or second sensing device performs perception using non-radar sensing principles.

[0054] Specifically, the original data is obtained by processing the received reflected signal when the first sensing device or the second sensing device adopts the radar sensing principle to perform perception; the spectral information is obtained by processing the obtained original data when the first sensing device or the second sensing device adopts the radar sensing principle to perform perception; the point cloud information is obtained by processing the obtained spectral information when the first sensing device or the second sensing device adopts the radar sensing principle to perform perception.

[0055] In an optional embodiment, the spectrum information or point cloud information includes at least one of the following: the time delay between the first sensing device or the second sensing device receiving the reflected signal of the reflection point and sending the sensing signal, the strength of the reflected signal, the azimuth arrival angle of the reflected signal relative to the first sensing device or the second sensing device, the pitch arrival angle of the reflected signal relative to the first sensing device or the second sensing device, the azimuth angle of the speed direction of the sensing object relative to the first sensing device or the second sensing device, the pitch angle of the speed direction of the sensing object relative to the first sensing device or the second sensing device, the speed magnitude of the reflection point relative to the first sensing device or the second sensing device, the timestamp of the spectrum information or the point cloud information, and the data source of the spectrum information or the point cloud information.

[0059] In a fourth aspect, an embodiment of the present application provides a communication method, which can be executed by a perception function network element. The perception function network element here can refer to the perception function network element itself, or to a processor, module, chip, or chip system that implements the method in the perception function network element. In this method, the perception function network element obtains one or more perception data types supported by the first perception device, and sends a first indication to the first perception device, where the first indication is used to indicate a first perception data type determined from the one or more perception data types. The perception function network element receives a perception service request for a first perception service from a service requester. Based on the perception service request, the perception function network element sends perception control information to the first perception device, where the perception control information is used to request the first perception device to perform the first perception service. The perception function network element receives perception data of the first perception data type from the first perception device, where the perception data is obtained by the first perception device performing the first perception service.

[0060] In an embodiment of the present application, the perception function network element determines, based on one or more perception data types supported by the first perception device, that the type of perception data reported by the first perception device to the perception function network element is the first perception data type, and indicates the type of the first perception data to the first perception device. Thus, when the perception function network element determines, based on the perception service request from the service requester, that the first perception device executes the first perception service in the perception service request, this facilitates the first perception device to execute the first perception service, obtain perception data of the first perception data type, and transmit the perception data of the first perception data type to the perception function network element, thereby improving perception efficiency.

[0061] In an optional embodiment, the sensing function network element sends sensing control information to a first sensing device based on a sensing service request, including: determining the first sensing device based on a sensing area in the sensing service request; and sending the sensing control information to the first sensing device. The first sensing device is a sensing device within the sensing area.

[0062] In an optional embodiment, the perception function network element determines the first perception device based on the perception area in the perception service request, including: determining one or more perception devices based on the perception area in the perception service request; determining the first perception device based on the perception data type supported by one or more perception devices, and the first perception data type supported by the first perception device supports the first perception service.

[0063] In an optional embodiment, the first perception data type supports the first perception service, including: the first perception data type satisfies the perception data type and / or perception result type of the first perception service. The perception data type and / or perception result type of the first perception service is carried in the perception service request, or the perception data type and / or perception result type of the first perception service is determined based on the perception information in the perception service request and / or the authorization information of the service requester. The authorization information of the service requester includes the perception result type authorized by the service requester.

[0064] It can be seen that the perception function network element determines one or more perception devices located in the perception area, and then determines the first perception device whose perception data type supported by the one or more perception devices meets the perception data type and / or perception result type of the first perception service as the perception device that executes the first perception service, thereby sending perception control information to the first perception device to request the first perception device to execute the first perception service.

[0065] In an optional implementation, the perception information includes at least one of the following: perception service type, perception principle, perception performance index requirement, data fusion effect index requirement, security and privacy requirements, operator policy, perception mode, perception device type, perception data type supported by the perception device, or processing capability of the service requester.

[0066] In an optional implementation, the perception function network element sends information indicating the perception result type of the first perception service to the service requester. This approach enables the service requester to learn that the perception function network element can open the perception result of the perception result type of the first perception service to the service requester.

[0067] In an optional implementation, the perception function network element further receives a perception result type from a service requester, where the perception result type of the service requester is used to indicate the perception result requested by the service requester. Thus, the perception function network element sends information indicating the perception result type of the first perception service to the service requester, including: when the perception result type of the service requester is different from the perception result type of the first perception service, sending information indicating the perception result type of the first perception service to the service requester.

[0068] It can be seen that when the type of perception result requested by the service requester is different from the type of perception result of the first perception service, the perception function network element indicates the type of perception result of the first perception service to the service requester. This method allows the service requester to know that the perception function network element cannot open the requested perception result to the service requester, and can open the perception result of the perception result type of the first perception service.

[0069] In an optional implementation, the perception function network element further sends a perception result of the perception result type of the first perception service to the service requester based on the perception data. This approach facilitates the service requester to perform perception identification based on the perception result.

[0070] In an optional embodiment, the perception function network element further performs the following steps: obtaining one or more perception principles supported by the first perception device; and sending a second indication to the first perception device, where the second indication indicates a first perception principle determined from the one or more perception principles. This approach facilitates the first perception device and / or the second perception device to perform perception services based on the first perception principle indicated by the perception function network element, thereby improving perception efficiency.

[0071] In an optional embodiment, the perception function network element also sends information indicating the intermediate data type to the second perception device. The intermediate data type is used by the second perception device to determine the intermediate data to be sent to the first perception device, and the intermediate data is used by the first perception device to obtain perception data of the first perception data type.

[0072] In one optional embodiment, the first sensing data type is one of raw data, spectral information, point cloud information, non-point cloud information, and sensing results. The raw data, spectral information, point cloud information, and sensing results are obtained when the first sensing device or the second sensing device performs sensing using radar sensing principles. The non-point cloud information is obtained when the first sensing device or the second sensing device performs sensing using non-radar sensing principles.

[0170] The technical solutions in the embodiments of the present application are described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0171] To better understand the embodiments of the present application, the following first introduces the system architecture involved in the embodiments of the present application:

[0172] The embodiments of the present application can be applied to fourth-generation (4G) communication systems such as long-term evolution (LTE) systems and fifth-generation (5G) communication systems such as new radio (NR) systems. As communication technology continues to develop, the technical solutions of the embodiments of the present application can also be used for subsequently evolved communication systems, such as sixth-generation (6G) mobile communication technology systems and seventh-generation (7G) mobile communication technology systems.

[0173] Please refer to Figure 1, which is a schematic diagram of a system architecture provided by an embodiment of the present application. The system architecture includes network functional entities such as terminal equipment, (radio) access network ((R)AN), user plane function (UPF), data network (DN), access and mobility management function (AMF). As shown in Figure 1, the terminal device can access the wireless network to obtain services of the external network (such as the data network (DN)) through the wireless network, or communicate with other devices through the wireless network, such as communicating with other terminal devices. The following is a detailed description of the equipment / functional network elements involved in the system architecture in Figure 1.

[0174] Terminal devices may include various handheld devices with wireless communication capabilities, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem. Terminal devices may also be referred to as terminals. Terminal equipment may also refer to user equipment (UE), access terminal, subscriber unit, user agent, cellular phone, smart phone, wireless data card, personal digital assistant (PDA), tablet computer, wireless modem, handheld device, laptop computer, smart point of sale (POS), customer-premises equipment (CPE), machine type communication (MTC) terminal, communication equipment carried by high-altitude aircraft, wearable device, drone, robot, device to device (D2D) terminal, vehicle to everything (V2X) terminal, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical, smart grid, etc. This application does not limit the wireless terminals in the future communication network, such as wireless terminals in the mobile grid, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, or terminal devices in future communication networks.

[0175] The RAN is a network consisting of multiple 5G-RAN nodes that implements wireless physical layer functions, resource scheduling and radio resource management, radio access control, and mobility management. The 5G-RAN connects to the UPF via the user plane interface N3 to transmit data from terminal devices. The 5G-RAN establishes a control plane signaling connection with the AMF via the control plane interface N2 to implement functions such as radio access bearer control. RAN nodes can be base stations in 5G networks or base stations in future evolved communication systems, broadband network gateways (BNGs), aggregation switches, or non-3GPP access devices. Optionally, the RAN nodes in the embodiments of the present application may include various forms of base stations, such as: macro base stations, micro base stations (also called small stations), relay stations, access points, devices that implement base station functions in communication systems evolved after 5G, transmission and receiving points (TRP), transmitting points (TP), integrated access and backhaul nodes (IAB nodes), mobile switching centers, and devices that perform base station functions in D2D and machine-to-machine (M2M) communications, etc. The embodiments of the present application do not specifically limit this.

[0176] The following network functional entities can be understood as core network equipment:

[0177] The AMF network element is mainly responsible for UE authentication, UE mobility management, network slice selection, session management function (SMF) selection and other functions; the AMF network element serves as the anchor point for N1 and N2 signaling connections and provides routing of N1 / N2 SM messages for SMF network elements; the AMF network element maintains and manages UE status information.

[0178] The SMF network element is mainly responsible for all control plane functions of UE session management, including UPF selection, Internet Protocol (IP) address allocation, session quality of service (QoS) management, and obtaining policy and charging control (PCC) policies (from the policy control function (PCF)).

[0179] As the anchor point for protocol data unit (PDU) session connections, the UPF network element is responsible for filtering user equipment data packets, data transmission / forwarding, rate control, and generating billing information.

[0180] The unified data management (UDM) network element is mainly responsible for managing user data, such as the management of contract information, including obtaining contract information from the unified data repository (UDR) network element and providing it to other network elements (such as the AMF network element); generating third generation partnership project (3GPP) authentication credentials for the UE; and registering and maintaining the network element currently serving the UE (for example, the AMF represented by AMF ID1 is the UE's current serving AMF).

[0181] The UDR network element is mainly used to store user data, including subscription data called by the UDM network element, policy information called by the PCF network element, structured data for capability exposure, and application data called by the network element function (NEF) network element.

[0182] The NEF network element is a network capability exposure network element used to connect other internal network elements of the core network and the interaction between the core network external application servers to provide network capability information to the external application servers, or to provide information of the external application servers to the core network network elements.

[0183] The application function (AF) network element interacts with the core network element to provide some services. For example, it interacts with the PCF network element to perform service policy control, interacts with the NEF network element to obtain some network capability information or provide some application information to the network, and provides some data network access point information to the PCF network element to generate routing information for corresponding data services.

[0184] The authentication service function (AUSF) network element is used to perform security authentication on the UE when the UE accesses the network.

[0185] The network slice selection function (NSSF) network element selects a set of slice instances for the UE, determines the AMF set and allowed slice selection assistance information (NSSAI) for the UE.

[0186] The PCF network element provides configuration policy information for the UE and provides policy information for controlling the UE to the control plane network elements of the network (such as AMF network elements and SMF network elements).

[0187] It is understandable that when the solution of the embodiment of the present application is applied to 6G or future communication systems, the corresponding network function entity name may change, and this application does not limit this.

[0188] The wireless frequency bands used by network devices or terminal devices (such as 4G, 5G, 6G, millimeter wave, and terahertz bands) possess sensing capabilities, enabling wireless communication systems to sense and identify specific areas, objects, or events, addressing sensing needs in a wide range of scenarios. For example, in the case of smart transportation and unmanned aerial vehicles (UAVs), where the vehicle or drone's own sensing range is short or non-line-of-sight (NLOS) paths are inaccessible, wireless communication systems can generate large-scale, multi-perspective sensing information based on base station and terminal device perception for applications such as route planning, collision avoidance, and automated driving assistance. For another example, if a vehicle or drone experiences a dangerous event such as the sudden appearance of a person or object while driving, the wireless communication system can identify the event based on perception and notify the terminal device to perform emergency operations. For another example, when monitoring driving violations, such as vehicles occupying emergency lanes or drones leaving their routes, the wireless communication system can identify the violation based on perception and issue real-time alerts or post-event penalties. For another example, if a foreign object (human, animal, falling rock, etc.) intrudes onto a highway or railway track, or a drone intrudes into a no-fly zone (e.g., an airport), the wireless communication system can identify the foreign object based on perception and perform real-time emergency response. For another example, for home health monitoring scenarios, such as detecting abnormal postures such as falls, the wireless communication system can identify abnormal postures based on perception and issue an alarm. For another example, for health monitoring such as human breathing / heartbeat, the wireless communication system can identify abnormal indicators based on perception and issue an alarm. For another example, for meteorological monitoring scenarios, the wireless communication system can sense, detect, or predict environmental, climate, and weather changes.

[0189] Please refer to Figure 2, which is a schematic diagram of a RAN performing sensing services. As shown in Figure 2, the RAN can use communication resources to communicate with communication users and use sensing resources to perform sensing of sensing targets. Its communication resources and sensing resources are time-division multiplexed. In addition, the beams used by the RAN for communication and sensing are spatially multiplexed. The RAN can use some beams to communicate with communication users and use other beams to perform sensing of sensing targets. The RAN sensing process includes sending sensing signals to the sensing area, receiving reflected signals from sensing targets within the sensing area, and processing them to obtain sensing data.

[0190] Please refer to Figure 3, which is a perception diagram. Specifically, Figure 3 is a perception diagram in a V2X scenario. As shown in Figure 3, key performance indicators in a V2X scenario include range resolution, velocity resolution, angular measurement accuracy, and horizontal field of view (FOV). Range resolution α refers to the ability to distinguish adjacent targets by distance, typically measured as the minimum resolvable distance interval, and can be used to identify different vehicles. Velocity resolution β refers to the ability to distinguish targets by radial velocity, typically measured as the minimum resolvable velocity interval, and can be used to distinguish vehicles at different speeds. Angular measurement accuracy θ refers to the error between the measured and true angle of the target being measured and can be used to determine the lane in which the vehicle is located. The horizontal field of view (FOV) refers to the range that the perception device can cover. For example, as shown in Figure 3, when the FOV is 120 degrees, the two-way blind spot range is less than 18 meters on a 30-meter two-way road width, and the blind spot area ratio is less than 1%.

[0191] Please refer to Figure 4, which is a schematic diagram of a perception process. As shown in Figure 4, the AF network element sends a perception service request to the sensing function (SF) network element through the NEF network element. The SF network element sends a perception control command to the RAN and / or UE through the AMF network element; or, the SF network element sends the perception control command directly to the RAN and / or UE. The RAN and / or UE perform perception based on the perception requirements in the perception control command and report the acquired perception data to the SF network element. For example, the RAN or UE sends perception data to the SF network element through the UPF network element; or, the RAN or UE sends perception data directly to the SF network element. The SF network element performs data calculation on the received perception data to obtain a perception result. The SF network element sends a perception service response to the AF network element through the NEF network element. The perception service response includes the perception result.

[0192] It should be noted that the SF network element can be one of the network elements in the 5G core network (5G core, 5GC) or a non-core network element, and this application does not specifically limit this. When the SF network element is one of the network elements in the 5G core network, the SF network element can be connected to other network elements in the 5G core network through a service-based architecture (SBA) interface, that is, it can communicate with other network elements in the 5G core network through the SBA interface. When the SF network element is a non-core network element, the SF network element cannot be connected to other network elements in the 5G core network through the SBA interface. At this time, it may be necessary to interact with other 5G core network elements through the transit of NEF. Optionally, the SF network element can be implemented by other network elements in the core network.

[0193] In addition, SF can be an independently deployed network element or a network element co-located with other devices. For example, SF can be an independently deployed network element in the core network or a network element co-located with other core network devices.

[0194] The perception data obtained by the sensing device (such as the RAN or UE) through sensing is categorized by the data processing stage into raw data, spectral information, point cloud information, and sensing results. Raw data can be the in-phase / orthogonal data (i.e., I / Q data) of the RF signal, or it can be understood as the time-domain digital signal obtained by the sensing device performing analog-to-digital (A / D) conversion on the received reflected signal (or echo signal). Spectral information includes the range velocity (RV) spectrum, range Doppler (RD) spectrum, range velocity angle (RVA) spectrum, and range Doppler angle (RDA) spectrum. Point cloud information can be understood as the location and velocity information of the scattering points detected by the sensing device. The sensing result can be understood as the location and velocity information of the target after aggregating multiple scattering points into a single target. Optionally, the sensing result can also include information such as the target size and outline. The spectrum information and / or point cloud information can also be referred to as intermediate information, intermediate processing information, or pre-processing information. Furthermore, if the sensing device uses a non-radar sensing principle to perform sensing detection, the sensing data obtained by the sensing device can be non-point cloud information. For example, in rainfall monitoring, the sensing data is the reference signal receiving power (RSRP) of the reflected signal corresponding to the detection area information.

[0195] As can be seen, raw data, spectral information, point cloud information, and perception results are obtained when the perception device uses radar sensing principles to perform perception. Specifically, raw data is obtained by processing the received reflected signals when the perception device uses radar sensing principles; spectral information is obtained by processing the raw data when the perception device uses radar sensing principles to perform perception; point cloud information is obtained by processing the spectral information when the perception device uses radar sensing principles to perform perception; and perception results are obtained by processing the point cloud information when the perception device uses radar sensing principles to perform perception. Non-point cloud information is obtained when the perception device uses non-radar sensing principles to perform perception.

[0196] In addition, the perception results that the core network equipment can open to the service requester depend on one or more of the following factors: the perception principle, the type of perception service, the perception service requirements, the processing capability of the service requester, the data fusion effect, the liability risk, the security and privacy risk, and the billing model.

[0197] The "sensing principle" refers to a sensing principle supported by the network, which may include radar sensing principles and / or non-radar sensing principles. The radar sensing principle processes the object reflection signal received by the receiver to obtain object feature information or event feature information. Alternatively, the radar sensing principle processes the wireless signal transmitted by the transmitter and the object reflection signal received by the receiver to obtain object feature information or event feature information. For example, object feature information includes at least one of the following: presence / absence of an object, position, speed, size, and outline. Event feature information includes at least one of the following: breathing / exhaling, standing / lying flat, person / no person, vehicle / no vehicle, and vehicle / car / motorcycle / person.

[0198] Non-radar sensing involves measuring changes in wireless channel state information to obtain object or event characteristics. Alternatively, this information can be obtained through a camera, ultrasound, or thermal imaging. Wireless channel state information can include at least one of RSRP, channel quality indicator (CQI), and latency.

[0199] Applications that utilize radar sensing principles include, but are not limited to, traffic control, autonomous driving assistance, UAV intrusion detection / avoidance / tracking, rain detection, human posture detection, breathing detection, and home intrusion detection. Applications that utilize non-radar sensing principles include, but are not limited to, rain detection, human posture detection, breathing detection, and home intrusion detection.

[0200] Perception service requirements refer to one or more of the following: refresh rate, perception events, accuracy, resolution, latency, detection rate, and false alarm rate. Services with refresh rate requirements (such as reporting the emergency lane situation on a highway with a period of 1 second) can be called continuous services or periodic perception services. Services that do not have refresh rate requirements or only request perception once (such as reporting the road conditions at 100 km on a highway) can be called single-shot perception services. Services with perception event requirements (such as detecting animals entering a highway) can be called event-based services. For example, when the perception service is dynamic map generation, the perception service requirements are continuous services, with a measurement accuracy of 1 meter, a resolution of 2 meters, a latency of 100ms, a detection rate of 99%, and a false alarm rate of 0.01%. For another example, when the perception service is home intrusion detection, the perception service requirements are event-based services, with a measurement accuracy of 3 meters, a latency of 1 second, a detection rate of 99.9%, and a false alarm rate of 1%. The processing capabilities of the service requester include, but are not limited to, computing power. Data fusion effect refers to the requirements for data fusion effectiveness, or the quality requirements, or the fusion level requirements (e.g., fusion at the level of raw data / spectral information / point cloud information / perception results). Liability risk refers to the level of risk associated with the perception service. Security and privacy risk refers to the risk associated with the execution of the perception service. Billing model refers to the billing model used by the operator when executing the perception service. Billing models include but are not limited to traffic plus accuracy billing and / or duration plus accuracy billing.

[0201] For example, when the perception principle supported by the network is the radar perception principle, the perception service type is autonomous driving assistance, the perception service requirement is continuous and / or the perception accuracy is 1m, the requesting party has strong processing capabilities, the data fusion effect index requirements are high (such as fusion at the spectral information or point cloud information level), the liability risk is high, and the billing mode is the traffic plus accuracy mode, the perception device can open at least one of the spectral information or point cloud information to the service requesting party.

[0202] For another example, the perception principle supported by the network is the radar perception principle, the perception service type is home intrusion detection, the perception service requirement is event-based, the processing capability of the service requester is weak (such as IoT devices), the data fusion effect indicator requirements are low, the liability risk is high, there are security and privacy risks, and the billing model is duration plus accuracy. In this case, the perception service can open the perception results to the service requester.

[0203] For another example, when the perception principle supported by the network is a non-radar perception principle, the perception service type is rainfall detection, the perception service requirement is continuity, the service requester has strong processing capabilities, high data fusion effect indicators, low liability risks, no security and privacy risks, and the billing model is duration plus accuracy, the perception service can open non-point cloud information to the service requester.

[0204] For different sensing services, sensing network elements expect different types of sensing data. This means that different sensing services have differentiated requirements for sensing data. Furthermore, even if different sensing services share the same sensing principles, their requirements for sensing data may vary. Currently, when sensing devices report sensing data to core network equipment, they don't know what type of data to report, which can reduce sensing efficiency.

[0205] In embodiments of the present application, the sensing mode can be self-transmitting and self-receiving, or self-transmitting and self-receiving, such as the sensing mode of A transmitting and A receiving, or A transmitting and B receiving. For example, the sensing mode is at least one of the following: base station A transmitting and self-receiving, base station A transmitting and base station B receiving, base station A transmitting and terminal device A receiving, terminal device A transmitting and self-receiving, terminal device A transmitting and base station A receiving, or terminal device A transmitting and terminal device B receiving. A transmitting and A receiving can be understood as: A transmitting a sensing signal to a sensing area, A receiving a reflected signal from a sensing object within the sensing area in response to the sensing signal, and A performing sensing and recognition based on the received reflected signal, or in other words, performing sensing and recognition based on the received reflected signal and the transmitted sensing signal. A transmitting and B receiving can be understood as: A transmitting a sensing signal to a sensing area, B receiving a reflected signal from a sensing object within the sensing area in response to the sensing signal, and A or B performing sensing and recognition based on the reflected signal, or in other words, performing sensing and recognition based on the received reflected signal and the transmitted sensing signal. The reflected signal can also be referred to as a scattered signal.

[0206] For example, when the sensing mode is base station A's self-transmission and self-reception, base station A transmits a sensing signal to the sensing area. Base station A receives reflected signals from sensing objects within the sensing area in response to the sensing signal. Base station A then senses and identifies the sensing objects based on the received reflected signals. For another example, when the sensing mode is base station A transmitting and terminal device A receiving, base station A transmits a sensing signal to the sensing area. Terminal device A receives reflected signals from sensing objects within the sensing area in response to the sensing signal. Terminal device A senses and identifies the sensing objects based on the received reflected signals. Alternatively, terminal device A processes the reflected signals and transmits sensing data obtained from the reflected signals to base station A. Base station A senses and identifies the sensing objects based on the sensing data.

[0207] In addition, the sensing mode in which base station A transmits and receives data is applicable to perception scenarios such as traffic control, autonomous driving assistance, drone intrusion detection / obstacle avoidance / tracking, flood / crowd detection, and smart factories / automated guided vehicle (AGV) tracking / collision avoidance. The measured data types can include raw data, spectral information, point cloud information, and sensing results. The sensing mode in which base station A transmits and base station B receives data is applicable to perception scenarios such as traffic control, autonomous driving assistance, drone intrusion detection / obstacle avoidance / tracking, flood / crowd detection, smart factories / automated guided vehicle (AGV) tracking / collision avoidance, and weather monitoring (such as rainfall monitoring). The measured data types can include raw data, spectral information, point cloud information, and final results, or non-point cloud information. The sensing mode in which base station A transmits and terminal device A receives data is applicable to perception scenarios such as health care (such as fall / respiratory monitoring), home intrusion detection, and smart factories (such as AGV tracking / collision avoidance). The measured data types can include raw data, spectral information, point cloud information, final results, or non-point cloud information. The perception scenarios applicable to the perception mode in which terminal device A sends and base station A receives are the same as those applicable to the above-mentioned "base station sends and terminal device receives" mode. The measured data types can be raw data, spectral information, point cloud information, final results, or non-point cloud information. The perception mode in which terminal device A transmits and receives independently is applicable to the perception scenarios of autonomous driving assistance and UAV tracking. The measured data types can be raw data, spectral information, point cloud information, final results, or non-point cloud information. The perception scenarios applicable to the perception mode in which terminal device A sends and terminal device B receives are the same as those applicable to the "terminal device A transmits and receives independently" mode. The measured data types are also the same as those measured by the "terminal device A transmits and receives independently" mode.

[0208] In an embodiment of the present application, the spectrum information or point cloud information includes at least one of the following: the time difference between the first sensing device or the second sensing device receiving the reflected signal at the reflection point and sending the sensing signal (such as the relative time of arrival (RTOA) or the time difference of arrival (TDOA)), the strength of the reflected signal (such as the RSRP of the reflected signal), the azimuth angle of arrival (Azimuth AoA) of the reflected signal relative to the first sensing device or the second sensing device, the zenith angle of arrival (Zenith AoA) of the reflected signal relative to the first sensing device or the second sensing device, the azimuth angle of the velocity direction of the sensing object relative to the first sensing device or the second sensing device, the elevation angle of the velocity direction of the sensing object relative to the first sensing device or the second sensing device, the velocity of the reflection point relative to the first sensing device or the second sensing device, the timestamp of the spectrum information or the point cloud information, and the data source of the spectrum information or the point cloud information. The reflection point can be understood as the reflection point of the object or the sensing object.

[0209] In another optional embodiment, the spectral information or point cloud information includes at least one of the following: the distance (range) between the reflection point and the first sensing device or the second sensing device, the azimuth angle of the reflection point relative to the first sensing device or the second sensing device, the pitch angle of the reflection point relative to the first sensing device or the second sensing device, the azimuth angle of the speed direction of the reflection point relative to the first sensing device or the second sensing device, the pitch angle of the speed direction of the reflection point relative to the first sensing device or the second sensing device, the speed magnitude of the reflection point relative to the first sensing device or the second sensing device, the timestamp of the spectral information or the point cloud information, and the data source of the spectral information or the point cloud information.

[0211] In an embodiment of the present application, the perception result includes at least one of the following: identification information (ID) of the perception object, the type (type) of the perception object, the confidence probability (probability) of the type of the perception object, the size (size) of the perception object, the length (length) of the perception object, the width (width) of the perception object, the height (height) of the perception object, the distance between the perception object and the first perception device or the second perception device, the azimuth angle of the perception object relative to the first perception device or the second perception device, the pitch angle of the perception object relative to the first perception device or the second perception device, the speed magnitude of the perception object relative to the first perception device or the second perception device, the speed direction azimuth angle of the perception object relative to the first perception device or the second perception device, the speed direction pitch angle of the perception object relative to the first perception device or the second perception device, the reflection cross-section (RCS) of the perception object, the timestamp of the perception result, and the data source of the perception result.

[0212] In another optional embodiment, the perception result includes at least one of the following: identification information of the perceived object, the type of the perceived object, the confidence probability of the type of the perceived object, the size of the perceived object, the length of the perceived object, the width of the perceived object, the height of the perceived object, the coordinates of the perceived object, the speed direction azimuth of the perceived object, the speed direction pitch angle of the perceived object, the speed magnitude of the perceived object, the reflection cross-sectional area of ​​the perceived object, the timestamp of the perception result, and the data source of the perception result.

[0213] In an embodiment of the present application, the non-point cloud information includes channel state information corresponding to the sensing area, where the channel state information includes at least one of received power, received quality, channel quality, or delay of a multipath signal. The received power may be RSRP, the received quality may be reference signal receiving quality (RSRQ), and the channel quality may be CQI.

[0214] In the embodiment of the present application, the first sensing device is a sensing device that needs to report sensing data to the SF network element. In addition, the sensing mode in the embodiment of the present application is a self-transmitting and self-receiving sensing mode, and when the sensing device is the first sensing device, the first sensing device is a sensing device that sends sensing signals to the sensing area, receives reflected signals from sensing objects in the sensing area in response to the sensing signals, and reports sensing data to the SF network element. When the sensing mode in the embodiment of the present application is a self-transmitting and self-receiving sensing mode, the sensing device further includes a second sensing device. In this case, the first sensing device is a sensing device that sends sensing signals to the sensing area and reports sensing data, and the second sensing device is a sensing device that receives reflected signals from sensing objects in the sensing area in response to the sensing signals and does not need to report sensing data to the SF network element. When the sensing mode in the embodiment of the present application is a self-transmitting and self-receiving sensing mode, the sensing device further includes a third sensing device. In this case, the third sensing device is a sensing device that sends sensing signals to the sensing area, and the first sensing device is a sensing device that receives reflected signals from sensing objects in the sensing area in response to the sensing signals and needs to report sensing data to the SF network element.

[0215] In the embodiment of the present application, the perception object is a target to be identified / perceived within the perception area, for example, the perception object is a vehicle / personnel / obstacle to be identified within the perception area. The embodiment of the present application does not limit the specific form of the perception object.

[0216] In the embodiment of the present application, the service requester may be an AF network element, or may be a UE, or may be a client, etc. The embodiment of the present application does not limit the specific form of the service requester.

[0217] In an embodiment of the present application, the SF network element may have a control plane and a user plane separated, that is, the SF control plane (SF-C) function and the SF user plane (SF-U) function are separated. The SF-C may send control commands to the sensing device via the control plane; the SF-U may receive sensing data from the sensing device via the data plane and optionally process the sensing data to obtain a sensing result. The SF-C may control the SF-U, for example, the SF-C may select an appropriate SF-U and configure one or more of the identification rules, processing rules, or routing rules for the sensing data to the SF-U. The sensing device may be the aforementioned RAN, or may be a terminal device.

[0218] Optionally, the SF network element may be a location management function (LMF) network element, or the SF network element may be a part of the LMF; or the SF network element and the LMF network element may be combined, without limitation.

[0219] An embodiment of the present application provides a communication method 100. In this method, a Service Provider (SF) network element determines a type of perception data based on perception information and sends information indicating the type of perception data to a first perception device. Consequently, the first perception device transmits perception data of the type of perception data indicated by the SF network element to the SF network element, improving perception efficiency. Furthermore, the perception data type is determined by the SF network element based on the perception information, facilitating matching of the perception data received by the SF network element with the differentiated perception information requirements.

[0220] An embodiment of the present application provides a communication method 200. Compared with communication method 100, in communication method 200, the Service Provider (SF) further determines, based on the type of perception result requested by the service requester, that the perception result type open to the service requester is a first perception result type. The SF then sends a perception result of the first perception result type to the service requester based on the perception data, thereby facilitating the service requester to perform perception identification based on the perception result.

[0221] An embodiment of the present application provides a communication method 300. In this method, a Service Provider (SF) network element determines, based on one or more SF data types supported by the first SF device, that the type of SF data reported by the first SF device is a first SF data type among the one or more SF data types. Thus, when the SF network element determines, based on a SF service request from a service requester, that the first SF device executes the first SF service in the SF service request, the first SF device executes the first SF service, obtains SF data of the first SF data type, and transmits the SF data of the first SF data type to the SF network element, thereby improving SF efficiency.

[0222] The present application embodiment proposes a communication method 100. FIG5 is an interaction diagram of the communication method 100. The communication method 100 is described from the perspective of the interaction between the perception function network element, the first perception device, and the service requester. The communication method 100 includes but is not limited to the following steps:

[0223] S501. A service requester sends a perception service request to a perception function network element. Correspondingly, the perception function network element receives the perception service request from the service requester.

[0224] The sensing service request is used to request the execution of a sensing service for a sensing area and includes sensing service information and the sensing area. Optionally, the sensing service information includes information indicating one or more of the sensing service type, sensing principle, sensing performance indicator requirements, data fusion effect indicator requirements, security and privacy requirements, or sensing mode.

[0225] Among them, perception service types include, but are not limited to, traffic control perception, automated assisted driving perception, health care perception, and weather monitoring perception. Perception principles refer to the principles employed by perception devices to perform perception services, including but not limited to radar perception principles and / or non-radar perception principles. Radar and non-radar perception principles are described above and are not further elaborated here. Optionally, perception principles may also include a correspondence between perception principles and service types. Perception performance requirements refer to certain performance indicators required by perception services, including but not limited to range accuracy, range resolution, velocity accuracy, velocity resolution, angle accuracy, angle resolution, detection rate, and false alarm rate. Data fusion effect requirements can range from high to low data fusion effect requirements. For example, the perception service for automated assisted driving has high data fusion effect requirements, while the perception service for road management has low data fusion effect requirements. Security and privacy requirements refer to the privacy of the performed perception services. For example, the perception service for breathing detection has high privacy requirements, while the perception service for traffic flow and speed monitoring has low privacy requirements. Operator policy refers to the operator's billing policy. The perception mode is spontaneous and self-receiving, or spontaneous and self-receiving separately. The specific modes of spontaneous and self-receiving and spontaneous and self-receiving separately can be found above and will not be repeated here.

[0226] It is understandable that when the service requester determines that it is necessary to perform perception identification on the perception object in the perception area, it sends a perception service request to the SF network element to request execution of the perception service on the perception area.

[0227] In an optional implementation, when the service requester is a terminal device, the terminal device sends a perception service request to the SF network element through the AMF network element. The AMF network element may transparently transmit the perception service request, or the AMF network element may parse the perception service request and then send the relevant information elements in the perception service request to the SF network element via a new message. Optionally, the AMF network element may also perform an authorization check on the perception service requested by the terminal device, such as checking whether the terminal device is authorized to perform and request the perception service.

[0228] In another optional implementation, when the service requester is an AF network element or a client, the AF network element or client may send a perception service request to the SF network element via the AMF network element. The AMF network element may transparently transmit the perception service request, or may parse the perception service request and then send the relevant information elements in the perception service request to the SF network element via a new message.

[0229] Among them, the AF network element or client can send the perception service request to the AMF network element in a variety of ways. For example, the AF network element or client sends the perception service request directly to the AMF network element. For another example, the AF network element or client sends the perception service request to the AMF network element through the NEF network element and the gateway mobile sensing center (GMSC) network element, where the NEF network element is responsible for authorization check of the AF network element / client, and the GMSC network element is responsible for selecting the appropriate AMF network element. For another example, the AF network element / client sends the service request to the AMF network element through the NEF network element, where the NEF network element is responsible for authorization check of the AF network element / client, and is responsible for selecting the appropriate AMF network element. For another example, the AF network element / client sends the perception service request to the AMF network element through the GMSC network element, where the GMSC network element is responsible for authorization check of the AF network element / client, and is responsible for selecting the appropriate AMF network element.

[0230] In another optional implementation, the AF network element or client does not send the perception service request to the SF network element through the AMF network element. For example, the AF network element or client sends the perception service request directly to the SF network element. For another example, the AF network element or client sends the perception service request to the SF network element through the NEF network element and the GMSC network element. The NEF network element is responsible for performing authorization checks on the AF network element / client, and the GMSC network element is responsible for selecting a suitable SF network element. For another example, the AF network element or client sends the perception service request to the SF network element through the NEF network element. The NEF network element is responsible for performing authorization checks on the AF network element / client, and is responsible for selecting a suitable SF network element. For another example, the AF network element or client sends the perception service request to the SF network element through the GMSC network element. The GMSC network element is responsible for performing authorization checks on the AF network element / client, and is responsible for selecting a suitable SF network element.

[0231] S502. The perception function network element determines the perception data type based on the perception information.

[0232] It is understandable that the SF network element determines the type of perception data reported by the first perception device to the SF based on the perception information, thereby facilitating the first perception device to report the perception data of the perception data type.

[0233] Among them, the perception data type is one of raw data, spectral information, point cloud information, non-point cloud information and perception results. The raw data, spectral information, point cloud information, non-point cloud information and perception results can be referred to as described above and will not be repeated here.

[0234] In an optional implementation, the perception information includes at least one of the following: perception service type, perception principle, perception performance index requirement, data fusion effect index requirement, security and privacy requirements, operator policy, perception mode, perception device type, perception data type supported by the perception device, or processing capability of the service requester.

[0235] The sensing service type, sensing principle, sensing performance indicator requirements, data fusion effect indicator requirements, security and privacy requirements, or one or more of the sensing modes are described in S501 above and are not further described. The sensing device may be a wireless access device, such as a base station, or a terminal device. The processing capability of the service requester may be the computing power of the service requester, such as the ability of the service requester to process data. For example, the processing capability of a terminal is weak, while that of an application server is strong.

[0236] In addition, one or more of the perception service type, perception principle, perception performance index requirement, data fusion effect index requirement, security and privacy requirement, and perception mode may be determined by the SF network element based on the perception service information in the perception service request.

[0237] Optionally, one or more of the following: a sensing service type, a sensing principle, a sensing performance indicator requirement, a data fusion effect indicator requirement, a security and privacy requirement, and a sensing mode are carried in the sensing service request. Thus, the SF network element determines one or more of the following: a sensing service type, a sensing principle, a sensing performance indicator requirement, a data fusion effect indicator requirement, a security and privacy requirement, and a sensing mode based on the received sensing service request.

[0238] The operator policy may be determined by the operator and configured into the SF network element. For example, the operator policy is negotiated in advance with one or more perception application vendors and configured into the SF network element. The perception data types supported by the perception device may be actively reported by the perception device to the SF network element, or reported by the perception device to the SF network element based on the request of the SF network element, or obtained by the SF network element from other core network elements. The processing capability of the service requester may be actively reported by the service requester to the SF network element, or reported by the service requester to the SF network element based on the request of the SF network element, or obtained by the SF network element from other core network elements.

[0239] Exemplarily, when the perception service type is traffic control perception or autonomous driving perception, the SF network element determines the perception data type to be one of spectral information and point cloud information. Exemplarily, when the perception service type is weather detection perception, the SF network element determines the perception data type to be non-point cloud information. Exemplarily, when the perception service type is health care perception, the SF network element determines the perception data type to be a perception result.

[0240] Exemplarily, when the types of perception data supported by the perception device are spectral information and point cloud information, the SF network element determines that the perception data type is spectral information or point cloud information. Exemplarily, when the security and privacy requirements of the perception service are greater than the preset requirements, or when the security and privacy requirements are high, the SF network element determines that the perception data type is one of raw data, spectral information, and point cloud information. Exemplarily, when the security and privacy requirements of the perception service are less than or equal to the requirements, or when the security and privacy requirements are low, the SF network element determines that the perception data type is the perception result. Exemplarily, when the security and privacy requirements of the perception service are less than or equal to the preset requirements, and the types of perception data supported by the first perception device are point cloud information and perception results, the SF network element determines that the perception data type is the perception result.

[0241] Exemplarily, the perception service type is traffic control perception, or autonomous driving perception, the perception principle is radar perception principle, the data fusion effect index requirement is higher than the preset value, the security and privacy requirements are higher than the preset requirements, the processing ability of the service requester is higher than the preset capability, the operator strategy is a traffic plus precision mode, and the SF network element determines that the perception data type is spectral information or point cloud information.

[0242] For example, the perception service type is health care perception, the data fusion effect indicator requirement is lower than the preset value, the security and privacy requirements are lower than the preset requirements, the processing ability of the service requester is lower than the preset capability, the operator strategy is a time plus accuracy mode, and the SF network element determines the perception data type as the perception result.

[0243] In an optional implementation, the SF network element determines the type of perception data based on the perception information, including: determining a first perception result type open to the service requester based on the perception information and the service requester's authorization information, where the service requester's authorization information includes the perception result type authorized by the service requester; and determining the perception data type based on the first perception result type. Optionally, the perception result type authorized by the service requester may be preconfigured in the NEF network element, the SF network element, or other core network elements. For example, during the registration phase of the service requester, the SF network element authorizes the perception result type for the service requester.

[0244] In another optional implementation, the SF network element determines the perception data type based on the perception information, including: determining a first perception result type open to the service requester based on the perception information; and determining the perception data type based on the first perception result type.

[0245] In addition, the perception result of the first perception result type is data obtained by processing the perception data of the perception data type, or the first perception result type is the same as the perception data type. The manner in which the SF network element determines the perception data type based on the determined first perception result type facilitates the SF network element determining the perception result of the first perception result type open to the service requester based on the obtained perception data.

[0246] For example, if the SF network element determines, based on the perception information and the authorization information of the service requester, or the SF network element determines, based on the perception information, that the first perception result type open to the service requester is raw data, then the SF network element determines the perception data type to be raw data. For another example, if the SF network element determines, based on the perception information and the authorization information of the service requester, or the SF network element determines, based on the perception information, that the first perception result type open to the service requester is spectral information, then the SF network element determines the perception data type to be raw data or spectral information. For another example, if the SF network element determines, based on the perception information and the authorization information of the service requester, or the SF network element determines, based on the perception information, that the first perception result type open to the service requester is point cloud information, then the SF network element determines the perception data type to be one of raw data, spectral information, and point cloud information. For another example, if the SF network element determines, based on the perception information and the authorization information of the service requester, or the SF network element determines, based on the perception information, that the first perception result type open to the service requester is a perception result, then the SF network element determines the perception data type to be one of raw data, spectral information, point cloud information, and perception result.

[0247] Optionally, the perception information may also include other information in addition to the perception service type, perception principle, perception performance index requirements, data fusion effect index requirements, security and privacy requirements, operator policy, perception mode, perception device type, perception data type supported by the perception device, and the processing capability of the service requester. The embodiments of this application do not limit the specific form of the perception information.

[0248] In an optional implementation, the SF network element may further send information indicating the first perception result type to the service requester. Thus, the service requester learns that the SF network element can open the perception result of the first perception result type to the service requester. The service requester can confirm whether it can receive the perception result of the first perception result type. If the service requester confirms that it can receive the perception result of the first perception result type, it sends an acknowledgement (ACK) to the SF network element. The ACK is used to confirm that the service requester can receive the perception result of the first perception result type; if the service requester confirms that it cannot receive the perception result of the first perception result type, the service requester sends a negative acknowledgement (NACK) to the SF network element. The NACK is used to indicate that the service requester cannot receive the perception result of the first perception result type. Optionally, when the service requester confirms that it can receive the perception result of the first perception result type, it does not send an ACK to the SF network element. When the SF network element does not receive an ACK or a NACK, it assumes that the service requester can receive the perception result of the first perception result type.

[0249] It can be seen that the SF network element can negotiate with the service requester that the type of the perception result open to the service requester is the first perception result type by indicating the first perception result type to the service requester.

[0250] S503. The sensing function network element sends information indicating the type of sensing data to the first sensing device. Correspondingly, the first sensing device receives the information indicating the type of sensing data from the sensing function network element.

[0251] The information indicating the type of the sensing data may be carried in the sensing control information sent by the SF to the first sensing device, where the sensing control information is used to request the first sensing device to perform the sensing service. Optionally, the information indicating the type of the sensing data is different from the sensing control information.

[0252] In an optional implementation, the SF network element sends information indicating the type of perception data to the first perception device, including: receiving a perception service request from a service requester; and sending information indicating the type of perception data to the first perception device based on the perception service request.

[0253] It can be seen that the SF network element receives a perception service request from the service requester, determines the first perception device based on the perception service request, and sends information indicating the type of perception data to the first perception device, so that the first perception device reports the perception data of the perception data type to the SF network element.

[0254] In an optional implementation, the perception function network element sends information indicating the type of perception data to the first perception device based on the perception service request, including: determining the first perception device based on the perception area in the perception service request; and sending information indicating the type of perception data to the first perception device.

[0255] It can be seen that the sensing service request includes the sensing area, and the SF network element determines the first sensing device in the sensing area as the sensing device performing the sensing service, thereby sending information indicating the type of sensing data to the first sensing device.

[0256] In an optional implementation, the perception function network element determines a first perception device based on a perception area in a perception service request, including: determining one or more perception devices based on the perception area in the perception service request; and determining a first perception device based on the perception data types supported by the one or more perception devices, wherein the first perception device supports the perception data type determined by the perception function network element. Optionally, if there are multiple perception devices among the one or more perception devices that support the perception data type determined by the SF network element, the SF network element may use any one of the multiple perception devices that support the determined perception data type as the first perception device.

[0257] It can be seen that the SF network element determines one or more sensing devices within the sensing area and determines the first sensing device among the one or more sensing devices that supports the determined sensing data type as the sensing device that performs the sensing service. For example, if the sensing data type determined by the SF network element is point cloud information, the one or more sensing devices within the sensing area include sensing device a and sensing device b, the sensing data types supported by sensing device a include raw data and spectral information, and the sensing data type supported by sensing device b is point cloud information, then the SF network element determines sensing device b as the first sensing device.

[0258] For another example, the perception data type determined by the SF network element is point cloud information, and the one or more perception devices in the perception area include perception device a, perception device b and perception device c. The perception data types supported by perception device a include raw data and spectral information, the perception data type supported by perception device b is point cloud information, and the perception data type supported by perception device c is point cloud information and perception results. Then the SF network element determines that the first perception device is perception device b or perception device c.

[0259] Optionally, the SF network element determines one or more sensing devices within the sensing area, and determines a sensing device among the one or more sensing devices whose supported sensing data type can match the sensing data type determined by the SF network element as the first sensing device. Optionally, if there are multiple terminal devices among the one or more terminal devices whose supported sensing data types can match the sensing data type determined by the SF network element, the SF network element will select any one of the multiple terminal devices that can match the sensing data type determined by the SF network element as the first sensing device.

[0260] The perception data types supported by the perception device can match the perception data types determined by the SF network element. This can be understood as follows: if the perception data of the perception data type determined by the SF network element can be determined based on the perception data types supported by the perception device, then the perception data supported by the perception device can match the perception data type determined by the SF network element. For example, if the perception data type supported by perception device a is raw data, and the perception data type determined by the SF network element is point cloud information, and the SF can determine point cloud information based on the raw data supported by perception device a, then the perception data type supported by perception device a can match the perception data type determined by the SF network element.

[0261] Exemplarily, the type of perception data determined by the SF network element is point cloud information. The one or more perception devices within the perception area include perception device a, perception device b, and perception device c. The perception data types supported by perception device a include raw data and spectral information. The perception data type supported by perception device b is point cloud information. The perception data type supported by perception device c is perception results. If the perception data supported by perception device a matches the point cloud information, and the perception data type supported by perception device b is the type of perception data determined by the SF network element, the SF network element determines that the first perception device is perception device a or perception device b.

[0262] It can be seen that before the perception function network element sends information indicating the type of perception data to the first perception device, it determines one or more perception devices located in the perception area and determines the first perception device among the one or more perception devices that supports or can match the type of perception data determined by the SF network element as the perception device that performs the perception service. Thus, the perception function network element sends information indicating the type of perception data to the first perception device to obtain perception data of the perception data type.

[0263] S504: The first sensing device sends sensing data of the sensing data type to the sensing function network element. Correspondingly, the sensing function network element receives the sensing data of the sensing data type from the first sensing device.

[0264] The first sensing device receives information indicating the type of sensing data from the SF network element and learns that it needs to report the sensing data of the sensing data type to the sensing function network element. Thus, the first sensing device sends the sensing data of the sensing data type to the SF network element.

[0265] Specifically, the first sensing device further receives sensing control information from the SF network element, the sensing control information including the sensing service type. Thus, the first sensing device performs a sensing service of the sensing service type, obtains sensing data of the sensing data type, and sends the sensing data of the sensing data type to the SF network element.

[0266] It can be seen that the SF network element indicates the type of the perception data reported to the first perception device, so that the first perception device sends the perception data of the perception data type to the SF network element, so that the SF network element obtains the perception data of the perception data type, which can improve perception efficiency. In addition, the SF network element indicates the perception data type to the first perception device, which can enable the first perception device to perform a perception service based on the perception data type and obtain the perception data of the perception data type, which can improve the perception efficiency of the first perception device in performing the perception service.

[0267] In an optional implementation, the SF network element may also determine a sensing mode based on the sensing service type, service performance indicator requirements, and sensing device capability information in the sensing service request, such as the sensing mode of self-transmission and self-reception or self-transmission and no-reception. Based on the sensing mode and the sensing service request, the SF network element then determines the sensing device to perform the sensing service.

[0268] In an optional embodiment, the sensing device determined by the SF network element is a first sensing device. The first sensing device sends a sensing signal to a sensing area and receives a reflection signal from a sensing object within the sensing area in response to the sensing signal. The first sensing device processes the received reflection signal to obtain sensing data of a sensing data type, and sends the sensing data of the sensing data type to the SF network element.

[0269] In another optional embodiment, the sensing device determined by the SF network element further includes a second sensing device, configured to receive a reflected signal from a sensing object within the sensing area in response to the sensing signal. In this embodiment, the SF network element may further transmit information indicating an intermediate data type to the second sensing device. The intermediate data type is used by the second sensing device to determine intermediate data to be sent to the first sensing device. The intermediate data is used by the first sensing device to obtain sensing data. The intermediate data type is determined by the SF network element based on the sensing data type.

[0270] As can be seen, when the SF network element determines that the sensing devices performing the sensing service include a first sensing device and a second sensing device, the SF network element sends information indicating the intermediate data type to the second sensing device, and sends information indicating the sensing data type to the first sensing device. The first sensing device sends a sensing signal to the sensing area, and the second sensing device receives a reflected signal from a sensing object within the sensing area in response to the sensing signal. The second sensing device processes the reflected signal to obtain intermediate data of the intermediate data type, and sends the intermediate data to the first sensing device. The first sensing device processes the intermediate data from the second sensing device to obtain sensing data of the sensing data type, and sends the sensing data to the SF network element, so that the SF network element obtains the sensing data of the sensing data type.

[0271] Exemplarily, the SF network element determines that the sensing devices performing the sensing service include sensing device A and sensing device B. Sensing device A is the sensing device that sends sensing signals and reports sensing data, and sensing device B is the sensing device that receives reflected signals. The sensing data type is point cloud information. Based on the sensing data type, the SF network element determines that the intermediate data type is spectral information. The SF network element sends information indicating that the sensing data type is point cloud information to sensing device A, and sends information indicating that the sensing data type is spectral information to sensing device B. Sensing device A sends the sensing signal to the sensing area, and sensing device B receives the reflected signal from the sensing object within the sensing area. Sensing device B processes the received reflected signal to obtain spectral information, and sends the determined spectral information to sensing device A. Sensing device A processes the spectral information to obtain point cloud information, and sends the determined point cloud information to the SF network element. Thus, the SF network element obtains sensing data of the point cloud information type.

[0272] Optionally, when the sensing device includes a first sensing device that reports the sensing data and a second sensing device that receives the reflected signal, the SF network element does not send information indicating the intermediate data type to the second sensing device. The first sensing device independently determines the intermediate data type based on the sensing data type and sends information indicating the determined intermediate data type to the second sensing device. Thus, the second sensing device processes the received reflected signal, obtains intermediate data of the intermediate data type, and sends the intermediate data to the first sensing device. The second sensing device processes the intermediate data from the first sensing device, obtains sensing data of the sensing data type, and sends the sensing data to the SF network element.

[0273] Optionally, when the perception device includes a first perception device that reports perception data and a second perception device that receives a reflected signal, the SF network element does not send information indicating the intermediate data type to the second perception device, and the first perception device does not send information indicating the intermediate data type to the second perception device. The second perception device processes the received reflected signal, obtains the original data, and sends the original data to the first perception device. The first perception device processes the original data from the second perception device, obtains perception data of the perception data type, and sends the perception data to the SF network element. In this manner, the SF does not need to send information indicating the intermediate data type to the second perception device, and the first perception device does not need to send information indicating the intermediate data type to the second perception device, which can reduce signaling overhead.

[0274] As can be seen, when the sensing device includes a first sensing device that reports sensing data and a second sensing device that receives a reflected signal, the second sensing device can send intermediate data obtained by processing the reflected signal to the first sensing device, or send raw data obtained by processing the reflected signal to the first sensing device. Regardless of whether the second sensing device sends intermediate data or raw data to the first sensing device, the first sensing device can process the received data to obtain sensing data of the sensing data type.

[0275] Optionally, when the sensing device includes a first sensing device that reports the sensing data and a third sensing device that transmits a sensing signal, the third sensing device transmits the sensing signal to the sensing area, and the first sensing device receives a reflected signal from a sensing object within the sensing area in response to the sensing signal. The first sensing device processes the received reflected signal to obtain sensing data of the sensing data type.

[0276] In an optional embodiment, when the type of perception data is one of raw data, spectral information, and point cloud information, the SF network element obtains perception data whose perception data type is raw data, or spectral information, or point cloud information, which is conducive to enriching the types of perception results that the SF network element opens to the service requester. For example, if the type of perception data is raw data, the SF network element obtains perception data whose data type is raw data, and then the SF network element can open data whose data type is raw data, or spectral information, or point cloud information, or perception results to the service requester. For another example, if the type of perception data is spectral information, the SF network element obtains perception data whose data type is spectral information, and then the SF network element can open data whose data type is spectral information, or point cloud information, or perception results to the service requester. If the type of perception data is point cloud information, the SF network element obtains perception data whose data type is point cloud information, and then the SF network element can open data whose data types are point cloud information and perception results to the service requester.

[0277] In an optional implementation, the first perception device may also send information indicating the type of perception data to the SF network element. That is, the first perception device may also report the type of perception data to the SF so that the SF confirms whether the received perception data is the type of perception data indicated by the SF. The perception data and the information indicating the type of perception data may be carried in the same information or in different information. For example, the type of perception data indicated by the SF network element to the first perception device is point cloud information, and the first perception device performs a perception service to obtain perception data whose data type is point cloud information, then the first perception device sends the perception data to the SF network element, as well as information indicating that the type of perception data is point cloud information, so that the SF network element confirms that the received perception data is the perception data that needs to be obtained.

[0278] In an optional implementation, if in the above S502, the SF network element and the service requester have negotiated that the type of perception result open to the service requester is the first perception result type, then the SF network element may also send a perception result of the first perception result type to the service requester based on the perception data. Specifically, the SF network element processes the perception data, obtains a perception result of the first perception result type, and sends the obtained perception result to the service requester. Optionally, the perception result may be carried in a perception service response. Thus, the service requester may apply the perception result to a perception application. For example, based on the perception result, the service requester determines information such as the location of the perception object, the type of the perception object, the speed of the perception object, and the direction of movement of the perception object. For another example, based on the perception result, the service requester determines that the detected person has fainted or is in other dangerous situations. For another example, based on the perception result, the service requester determines that a target of illegal intrusion appears in the perception area.

[0279] In an optional implementation, the SF network element may further perform the following steps: determining a sensing principle based on the sensing service type and sensing performance indicator requirements, where the sensing principle is a radar sensing principle or a non-radar sensing principle; and transmitting information indicating the sensing principle to the first sensing device and / or the second sensing device. Optionally, the SF network element may further determine the sensing principle based on other information in addition to the sensing service type and sensing performance indicator requirements.

[0280] The SF network element sending information indicating the sensing principle to the first sensing device and / or the second sensing device may be: the SF network element sending information indicating the sensing principle to the first sensing device and the second sensing device respectively; or the SF network element sending information indicating the sensing principle to the first sensing device, and the first sensing device then sending information indicating the sensing principle to the second sensing device; or the SF network element sending information indicating the sensing principle to the second sensing device, and the second sensing device then sending information indicating the sensing principle to the first sensing device. In short, both the first sensing device and the second sensing device can obtain the sensing principle determined by the SF network element.

[0281] If the first perception device receives information indicating a perception principle from the SF network element, then after receiving the perception control information from the SF network element, the first perception device performs a perception service based on the perception principle indicated by the SF network element and obtains perception data of the perception data type, thereby improving perception efficiency.

[0282] As can be seen, in this embodiment of the present application, the SF network element determines the type of perception data based on the perception information and sends information indicating the type of perception data to the first perception device. Consequently, the first perception device transmits perception data of the perception data type to the SF network element, improving perception efficiency. Furthermore, the fact that the perception data type is determined by the SF network element based on the perception information facilitates matching the perception data received by the SF network element with the differentiated perception information requirements.

[0283] The present application embodiment proposes a communication method 200. FIG6 is an interaction diagram of the communication method 200. The communication method 200 is also described from the perspective of the interaction between the perception function network element, the first perception device, and the service requester. The communication method 200 includes but is not limited to the following steps:

[0284] S601. The service requester sends a sensing service request to the sensing function network element, the sensing service request including information indicating a second sensing result type, the second sensing result type indicating the sensing result of the service requester. Correspondingly, the sensing function network element receives the sensing service request from the service requester.

[0285] The sensing service request is used to request execution of a sensing service for the sensing area. The sensing service request includes sensing service information and the sensing area. The sensing service information includes information indicating a second sensing result type, where the second sensing result type is one of raw data, spectral information, point cloud information, non-point cloud information, and a sensing result.

[0286] Optionally, the perception service information also includes information for indicating one or more of the perception service type, perception principle, perception performance index requirements, data fusion effect index requirements, security and privacy requirements, or perception mode. This implementation method can be found in S501 above and will not be repeated here.

[0287] The implementation method of sending the perception service request to the SF network element in the service request direction can be found in the above S501 and will not be repeated here.

[0288] It is understandable that when the service requester determines that it needs to perform perception and identification on the perception objects within the perception area, it sends a perception service request to the SF network element to request that the perception service be performed on the perception area. In addition, the perception service request includes information indicating the second perception result type, that is, the service requester also requests the SF network element to open the perception results of the second perception result type through the perception service request.

[0289] S602: When the second perception result type is different from the first perception result type, the perception function network element sends information indicating the first perception result type to the service requester. Correspondingly, the service requester receives the information indicating the first perception result type from the perception function network element.

[0290] Among them, the first perception result type is the perception result type determined by the SF network element based on the perception information and / or the authorization information of the service requester and open to the service requester, and the first perception result type is one of raw data, spectral information, point cloud information, non-point cloud information and perception results. The perception information can be referred to as described in S502 above and will not be repeated here. The authorization information of the service requester includes the perception result type authorized by the service requester. The perception result type authorized by the service requester can be the perception result type authorized by the SF network element or other core network element for the service requester during the registration stage of the service requester.

[0291] It can be seen that the service requester requests the SF network element to open the second perception result type through the perception service request, and when the second perception result type requested by the service requester is different from the first perception result type determined by the SF network element to be open to the service requester, the SF network element sends information indicating the first perception result type to the service requester. This method allows the service requester to know that the SF network element cannot open the requested perception result to the service requester and can open the perception result of the first perception result type.

[0292] Optionally, the service requester may confirm whether it can receive the perception result of the first perception result type. If the service requester confirms that it can receive the perception result of the first perception result type, it sends an ACK to the SF network element, and the ACK is used to confirm that it can receive the perception result of the first perception result type; if the service requester confirms that it cannot receive the perception result of the first perception result type, it sends a NACK to the SF network element, and the NACK is used to indicate that it cannot receive the perception result of the first perception result type. Optionally, when the service requester determines that it can receive the perception result of the first perception result type, the service requester does not send an ACK to the SF network element. When the SF network element does not receive an ACK or a NACK, it assumes that the service requester can receive the perception result of the first perception result type.

[0293] Optionally, when the second perception result type is the same as the first perception result type, the SF network element determines that the perception result of the second perception result type requested by the service requester can be opened to the service requester. When the SF network element determines that the perception result of the second result type can be opened to the service requester, it can send an ACK to the service requester, and the ACK is used to indicate that the SF network element can open the perception result of the second perception result type to the service requester. Optionally, when the SF network element determines that the perception result of the second result type can be opened to the service requester, it does not send an ACK to the service requester. When the service requester does not receive the ACK, or does not receive information indicating the first perception result type, it is assumed that the SF network element can open the perception result of the second perception result type to the service requester. Thus, the service requester and the SF network element reach an agreement, and the SF network element can subsequently open the perception result of the second perception result type to the service requester, that is, it can open the perception result of the first perception result type to the service requester.

[0294] Optionally, the perception service request does not include information indicating the second perception result type. After the service requester sends the perception service request to the SF network element, it then sends information indicating the second perception result type to the SF network element to request the SF network element to open the perception result of the second perception result type. It can be seen that the information indicating the second perception result type can be carried in information different from the perception service request.

[0295] In summary, the service requester can negotiate with the SF network element on the type of perception result to be opened to the service requester by actively indicating to the SF network element the type of perception result to be opened.

[0296] S603. The perception function network element determines the perception data type based on the perception information.

[0297] S604. The sensing function network element sends information indicating the type of the sensing data to the first sensing device. Correspondingly, the first sensing device receives the information indicating the type of the sensing data from the sensing function network element.

[0298] S605. The first perception device sends perception data of the perception data type to the perception function network element.

[0299] It is understandable that S603 to S605 can refer to the above-mentioned S502 to S504 and will not be repeated here.

[0300] S606. The perception function network element sends a perception result of the first perception result type to the service requester based on the perception data.

[0301] It is understandable that the SF network element and the service requester negotiate through S601 and S602 that the type of perception result open to the service requester is the first perception result type, so that the SF network element sends the perception result of the first perception result type to the service requester based on the perception data. Specifically, the SF network element processes the perception data to obtain a perception result of the first perception result type, and sends the obtained perception result to the service requester.

[0302] For example, if the type of the perception data is spectral information and the type of the first perception result is point cloud information, the SF network element processes the perception data, obtains a perception result whose data type is point cloud information, and sends the perception result whose data type is point cloud information to the service requester.

[0303] Optionally, after obtaining the perception result, the service requester further performs perception identification on the perception object in the perception area based on the perception result, or determines the result of the perception service based on the perception result.

[0304] Optionally, if the SF network element receives a NACK from the service requester indicating that the perception result of the first perception data type cannot be received, the SF network element does not execute S606, that is, the SF network element does not send the perception result of the first perception result type to the service requester based on the perception data.

[0305] As can be seen, in this embodiment of the present application, the service requester requests the SF network element to open the perception result of the second perception result type through the perception service request. Therefore, when the second perception result type is different from the first perception result type determined by the SF network element, the SF network element negotiates with the service requester to open the perception result type to the service requester as the first perception result type. Furthermore, the SF network element can open the perception result of the first perception result type to the service requester based on the obtained perception data.

[0306] In addition, the first sensing device sends sensing data of the sensing data type indicated by the SF network element to the SF network element, which can improve sensing efficiency. The sensing data type is determined by the SF network element based on the sensing information, which is conducive to matching the sensing data received by the SF network element with the differentiated requirements of the sensing information.

[0307] The present application embodiment proposes a communication method 300. FIG7 is an interaction diagram of the communication method 300. The communication method 300 is described from the perspective of the interaction between the perception function network element, the first perception device, and the service requester. The communication method 300 includes but is not limited to the following steps:

[0308] S701. The perception function network element obtains one or more perception data types supported by the first perception device.

[0309] Among them, the one or more perception data types supported by the first perception device include original data, spectral information, point cloud information, non-point cloud information and perception results.

[0310] In an optional embodiment, the first sensing device proactively reports one or more sensing data types supported by the first sensing device to the SF network element. Thus, the SF network element obtains the one or more sensing data types supported by the first sensing device, which may be: the SF network element receives the one or more sensing data types from the first sensing device, where the one or more sensing data types are sensing data types supported by the first sensing device.

[0311] In another optional implementation, when registering, signing a contract, or accessing a network, the first sensing device reports one or more sensing data types supported by the first sensing device to other core network elements. Thus, the SF network element obtains the one or more sensing data types supported by the first sensing device, which may be: the SF network element sensing service obtains the one or more sensing data types supported by the first sensing device from other core network elements.

[0312] In another optional implementation, the SF network element obtains one or more perception data types supported by the first perception device, which can be: the SF network element requests the first perception device to obtain the one or more perception data types supported by the first perception device, so that the first perception device directly reports the one or more perception data types supported by the first perception device to the SF network element; or, the first perception device reports the supported one or more perception data types to the SF network element through other core network network elements; accordingly, the SF network element receives the one or more perception data types supported by the first perception device through other core network network elements.

[0313] It can be seen that the SF network element can flexibly obtain one or more perception data types supported by the first perception device in a variety of ways.

[0314] S702. The sensing function network element sends a first indication to the first sensing device, where the first indication is used to indicate a first sensing data type determined from one or more sensing data types. Correspondingly, the first sensing device receives the first indication from the sensing function network element.

[0315] It is understandable that the SF network element obtains one or more perception data types supported by the first perception device, and determines a perception data type used by the first perception device when reporting perception data to the SF network element from the one or more perception data types. For example, the SF network element determines from the one or more perception data types that the perception data type used by the first perception device when reporting perception data to the SF network element is the first perception data type. The SF network element then indicates the first perception device type to the first perception device through a first indication, thereby facilitating the first perception device to report perception data of the first perception data type to the SF network element when performing a perception service. The first perception data type is one of raw data, spectral information, point cloud information, non-point cloud information, and perception results.

[0316] In an optional embodiment, when the SF network element obtains that the first perception device supports one perception data type, the first indication sent by the SF network element to the first perception device may be an accept message, which indicates that the SF network element can receive perception data of the perception data type supported by the SF network element. For example, the perception data type supported by the first perception device obtained by the SF network element is the first perception data type, and the first indication sent by the SF network element to the first perception device is an accept message, and the accept message is used to indicate that the SF network element can receive perception data of the first perception data type. This method enables the SF network element to negotiate with the first perception device that when the first perception device reports perception data to the SF network element, it reports perception data of the first perception data type.

[0317] It can be seen that the SF network element obtains one or more perception data types supported by the first perception device, and uses a first indication to indicate to the first perception device the first perception data type determined from the one or more perception data types, and negotiates with the first perception device that the type of perception data reported to the SF is the first perception data type, thereby facilitating the first perception device to perform more efficient perception based on the first perception data type.

[0318] S703. The service requester sends a perception service request for the first perception service to the perception function network element. Correspondingly, the perception function network element receives the perception service request for the first perception service from the service requester.

[0319] It is understandable that when the service requester determines that the first perception service needs to be executed, it sends a perception service request for the first perception service to the SF network element. The implementation method of the service requester sending the perception service request for the first perception service to the SF network element can be referred to in S501 above and will not be repeated here.

[0320] S704. Based on the sensing service request, the sensing function network element sends sensing control information to the first sensing device, where the sensing control information is used to request the first sensing device to execute the first sensing service. Correspondingly, the first sensing device receives the sensing control information from the sensing function network element.

[0321] In an optional embodiment, the SF network element sends sensing control information to a first sensing device based on a sensing service request, including: determining the first sensing device based on a sensing area in the sensing service request; and sending the sensing control information to the first sensing device. The first sensing device is a sensing device in the sensing area. As can be seen, the sensing service request includes the sensing area, and the SF network element determines the first sensing device in the sensing area as the sensing device to execute the first sensing service, thereby sending the sensing control information to the first sensing device to request the first sensing device to execute the first sensing service.

[0322] In an optional implementation, the SF network element determines a first perception device based on a perception area in a perception service request, including: determining one or more perception devices based on the perception area in the perception service request; determining a first perception device based on the perception data type supported by one or more perception devices, and the first perception data type supported by the first perception device supports the first perception service.

[0323] It can be seen that the SF network element determines one or more sensing devices located in the sensing area, and then determines the first sensing device based on the sensing data types supported by the one or more sensing devices. The first sensing data type supported by the first sensing device supports the first sensing service.

[0324] Among them, the first perception data type supports the first perception service, including: the first perception data type satisfies the perception data type and / or perception result type of the first perception service, the perception data type and / or perception result type of the first perception service is carried in the perception service request, or the perception data type and / or perception result type of the first perception service is determined based on the perception information in the perception service request and / or the authorization information of the service requester.

[0325] In an optional embodiment, when the first perception data type is the perception data type of the first perception service, the first perception data type satisfies the perception data type and / or perception result type of the first perception service. Optionally, when the SF network element can obtain a perception result of the perception result type of the first perception service based on the perception data of the first perception data type, the first perception data type satisfies the perception data type and / or perception result type of the first perception service. For example, the first perception data type is raw data, the perception result type of the first perception service is point cloud information, and the SF network element can process data whose data type is raw data to obtain data whose data type is point cloud information. In this case, the SF network element determines that the first perception data type satisfies the perception data type and / or perception result type of the first perception service. For another example, the first perception data type is spectral information, the perception result type of the first perception service is point cloud information, and the SF network element can process data whose data type is spectral information to obtain data whose data type is point cloud information. In this case, the SF network element determines that the first perception data type satisfies the perception data type and / or perception result type of the first perception service.

[0326] In an optional implementation, the service request of the first sensing service includes the sensing data type and / or sensing result type of the first sensing service. Thus, the SF network element obtains the sensing data type and / or sensing result type of the first sensing service based on the service request of the first sensing service.

[0327] In another optional implementation, the perception data type and / or perception result type of the first perception service is determined by the SF network element based on the perception information in the perception service request and / or the authorization information of the service requester. The perception information includes but is not limited to at least one of the following: perception service type, perception principle, perception performance index requirements, data fusion effect index requirements, security and privacy requirements, operator policy, perception mode, perception device type, perception data type supported by the perception device, and processing capability of the service requester. The specific implementation method of the perception information can be found in S502 above and will not be repeated here. The authorization information of the service requester includes the perception result type authorized by the service requester. The perception result type authorized by the service requester can be the perception result type authorized by the SF network element or other core network element for the service requester during the registration phase of the service requester.

[0328] Exemplarily, the perception service request of the first perception service includes the perception area as area A, the perception area A includes the perception device A and the perception device B, the perception data types supported by the perception device A are raw data and spectral information, the perception data types supported by the perception device B are point cloud information, and the perception data type of the first perception service is spectral information. The SF network element determines that the perception device A in the perception area performs the first perception service, that is, determines that the first perception device is the perception device A.

[0329] It is understood that when the first perception data type of the first perception device satisfies the perception data type and / or perception result type of the first perception service, it indicates that the SF network element is able to obtain the perception data and / or perception result required for the first perception service based on the perception data of the first perception data type. Thus, the SF network element determines the first perception device as the perception device for executing the first perception service. Furthermore, the SF network element sends perception control information to the first perception device, requesting the first perception device to execute the first perception service.

[0330] Optionally, the SF network element sends perception control information to the first perception device based on the perception service request, which is understood as: the SF network element determines whether the first perception device meets the requirements of the first perception service in the perception service request; if the SF determines that the first perception device meets the requirements of the first perception service, it determines that the first perception device executes the first perception service, thereby sending perception control information to the first perception device.

[0331] Optionally, the SF network element sends perception control information to the first perception device based on the perception service request, which is understood as: the SF network element determines whether the perception data type (i.e., the first perception data type) negotiated with the first perception device meets the requirements of the first perception service in the perception service request; if the first perception data type meets the requirements of the first perception service, it is determined that the first perception device executes the first perception service, thereby sending perception control information to the first perception device.

[0332] Optionally, the SF network element sends perception control information to the first perception device based on the perception service request, which is understood as: the SF network element determines whether the perception result type meets the requirements of the first perception service in the perception service request. The perception result type is determined by the SF network element based on the perception data type negotiated with the first perception device, that is, the perception result type is determined by the SF network element based on the first perception data type; if the SF determines that the perception result type meets the requirements of the first perception service, it determines that the first perception device executes the first perception service, thereby sending perception control information to the first perception device.

[0333] In summary, when the SF network element determines that the first perception data type meets the requirements of the first perception service in the perception service request, the SF network element determines that the first perception device performs the first perception service, and sends perception control information to the first perception device for requesting the first perception device to perform the first perception service.

[0334] In an optional embodiment, when the SF network element determines that the perception device executing the first perception service also includes a second perception device, the SF network element may also send information indicating an intermediate data type to the second perception device. The intermediate data type is determined by the SF network element based on the first perception data type and is used by the second perception device to obtain intermediate data. The intermediate data is used by the first perception device to obtain perception data of the first perception data type.

[0335] Optionally, when the SF network element determines that the perception device executing the first perception service also includes a second perception device, the first perception device may also send information indicating the intermediate data type to the second perception device. The intermediate data is determined by the first perception device based on the first perception data type and is used by the first perception device to obtain the intermediate data. The intermediate data is used by the first perception device to obtain perception data of the first perception data type.

[0336] Optionally, when the SF network element determines that the perception device executing the first perception service also includes a second perception device, the SF network element does not send information indicating the intermediate data type to the second perception device, and the first perception device does not send information indicating the intermediate data type to the second perception device. It is understandable that other implementations of the three implementations when the SF network element determines that the perception device executing the first perception service also includes a second perception device can be found in the communication method 100 and are not further described.

[0337] S705. The first perception device executes a first perception service to obtain perception data of a first perception data type.

[0338] As can be understood, the first sensing device receives the sensing control information from the SF network element, learns that it needs to execute the first sensing service, and thus executes the first sensing service. The first sensing device and the SF network element negotiate, through S701 and S702 above, that the type of sensing data to be reported to the SF is the first sensing data type. Therefore, the first sensing device executes the first sensing service and obtains sensing data of the first sensing data type.

[0339] In an optional implementation, if the SF network element determines that the sensing device performing the first sensing service is the first sensing device and other sensing devices are not included, the first sensing device sends a sensing signal to the sensing area and receives a reflected signal reflected by a sensing object in the sensing area in response to the sensing signal. The first sensing device processes the received reflected signal to obtain sensing data of the first sensing data type.

[0340] In another optional embodiment, the SF network element determines that the sensing device that performs the first sensing service includes not only a first sensing device that sends a sensing signal and reports sensing data, but also a second sensing device that receives a reflected signal. In this method, the first sensing device sends a sensing signal to the sensing area, and the second sensing device receives a reflected signal reflected by a sensing object within the sensing area in response to the sensing signal. If the second sensing device receives information indicating the type of intermediate data, the second sensing device processes the received reflected signal to obtain intermediate data of the intermediate data type, and sends the obtained intermediate data to the first sensing device. The first sensing device processes the received intermediate data to obtain sensing data of the first sensing data type.

[0341] Optionally, if the second sensing device does not receive information indicating the intermediate data type, the second sensing device receives a reflection signal from a sensing object within the sensing area in response to the sensing signal, processes the reflection signal, obtains raw data, and sends the obtained raw data to the first sensing device. The first sensing device processes the received raw data to obtain sensing data of the first sensing data type.

[0342] In another optional embodiment, the SF determines that the sensing device performing the first sensing service includes a first sensing device that reports sensing data and receives reflected signals, and also includes a third sensing device that transmits sensing signals. In this approach, the third sensing device transmits the sensing signal to the sensing area, and the first sensing device receives reflected signals from sensing objects within the sensing area. The first sensing device processes the received reflected signals to obtain sensing data of the first sensing data type.

[0343] In an optional implementation, the SF network element may further obtain one or more perception principles supported by the first perception device and send a second indication to the first perception device, where the second indication is used to indicate a first perception principle determined from the one or more perception principles. The manner in which the SF network element obtains the one or more perception principles supported by the first perception device can refer to the implementation in which the SF network element obtains one or more perception data types supported by the first perception device, and is not further described.

[0344] Understandably, the SF network element also pre-negotiates with the first sensing device the sensing principle used by the first sensing device to perform the sensing service. Thus, when the first sensing device performs the first sensing service, it uses the first sensing principle to perform the first sensing service and obtains sensing data of the first sensing data type, thereby improving the efficiency of the first sensing device in performing the first sensing service.

[0345] S706: The first sensing device sends sensing data of the first sensing data type to the sensing function network element. Correspondingly, the sensing function network element receives the sensing data of the first sensing data type from the first sensing device.

[0346] It is understandable that the SF network element and the first sensing device have pre-negotiated that the type of sensing data reported by the first sensing device is the first sensing data type. Therefore, if the SF network element selects the first sensing device to perform the first sensing service, the first sensing device performs the first sensing service, obtains sensing data of the first sensing data type, and transmits the obtained sensing data to the SF network element. This approach enables the SF network element to obtain sensing data of the first sensing data type negotiated with the first sensing device, thereby improving sensing efficiency.

[0347] In an optional implementation, the SF network element also sends information indicating the type of perception result of the first perception service to the service requester. The type of perception result of the first perception service can be referred to as described above and will not be repeated here. After the service requester receives the information indicating the type of perception result of the first perception service, it can also confirm whether it can receive the perception result of the perception result type of the first perception service. When the service requester confirms that it can receive the perception result of the perception result type of the first perception service, it sends an ACK to the SF network element, which is used to confirm that it can receive the perception result of the perception result type of the first perception service.

[0348] In another optional implementation, the SF network element further receives a perception result type from the service requester, where the perception result type of the service requester is used to indicate the perception result requested by the service requester. Thus, the SF network element sends information indicating the perception result type of the first perception service to the service requester, including: when the perception result type of the service requester is different from the perception result type of the first perception service, sending information indicating the perception result type of the first perception service to the service requester.

[0349] It can be seen that the service request direction sends the perception result type requested by the service requester to the SF network element. When the perception result type of the service requester is different from the perception result type of the first perception service, the SF sends information indicating the perception result type of the first perception service to the service requester. This method allows the service requester to know that the SF network element cannot open the requested perception result to the service requester, and can open the perception result of the perception result type of the first perception service. Optionally, the service requester can confirm whether it can receive the perception result of the perception result type of the first perception service. If the service requester confirms that it can receive the perception result of the perception result type of the first perception service, it sends an ACK to the SF, and the ACK is used to confirm that it can receive the perception result of the perception result type of the first perception service; if the service requester confirms that it cannot receive the perception result of the perception result type of the first perception service, it sends a NACK to the SF network element, and the NACK is used to indicate that it cannot receive the perception result of the perception result type of the first perception service. Optionally, when the service requester determines that it can receive the perception result of the perception result type of the first perception service, the service requester does not send an ACK to the SF network element. When the SF does not receive an ACK or NACK, it assumes that the service requester can receive the perception result of the perception result type of the first perception service.

[0350] It can be seen that the SF network element can negotiate with the service requester on the type of perception result open to the service requester by directly indicating the type of perception result of the first perception service to the service requester. Alternatively, the service requester can negotiate with the SF network element on the type of perception result open to the service requester by actively sending a message to the SF indicating the requested type of perception result.

[0351] In an optional implementation, if the service requester negotiates with the SF network element that the perception result type open to the service requester is the perception result type of the first perception service, the SF network element may further send a perception result of the perception result type of the first perception service to the service requester based on the perception data. Specifically, the SF network element processes the perception data to obtain a perception result of the perception result type of the first perception service, and sends the obtained perception result to the service requester, thereby facilitating the service requester to apply the perception result to a perception application.

[0352] As can be seen, in this embodiment of the present application, the SF network element determines, based on one or more types of perception data supported by the first perception device, that the type of perception data reported by the first perception device is the first perception data type among the one or more perception data types. Thus, when the SF network element receives a perception service request from a service requester and determines, based on the perception service request, that the first perception device execute the first perception service in the perception service request, the first perception device executes the first perception service, obtains perception data of the first perception data type, and sends the perception data of the first perception data type to the SF network element, thereby improving perception efficiency.
