[0001] Cross-reference to Related Applications

[0002] This application claims priority to the Chinese Patent Application No. 202411391715.4, filed on September 30, 2024, and entitled "A communication method, apparatus and system", the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] The present application relates to the field of communication technology, and in particular to a communication method, apparatus and system. BACKGROUND

[0004] With the development of communication technology, a communication sensing fusion technology is proposed. The core idea of the communication sensing fusion technology is to add sensing capability to the communication system, and to build the ability of target detection, tracking and imaging, so that the two capabilities of communication and sensing are integrated in one system. The communication system with added sensing capability can be referred to as an integrated sensing and communications (ISAC) system. The principle of the sensing technology is that the sending end sends a signal (also referred to as a sensing signal), the sensing signal reaches the sensing target, is reflected by the sensing target, the receiving end receives the reflected sensing signal (also referred to as a return signal), and processes the received return signal to obtain sensing data such as the position, speed or type of the sensing target.

[0005] At present, the sensing device (such as the above-mentioned receiving end) directly opens the obtained sensing data to the sensing request network element. However, the sensing data needs to be reasonably managed and opened, and therefore, how to accurately and efficiently provide the sensing data to the sensing request network element still needs further research. SUMMARY

[0006] The present application provides a communication method, apparatus and system, which introduces a label of sensing data to accurately and efficiently provide the sensing data to the sensing request network element.

[0007] In a first aspect, an embodiment of the present application provides a communication method, which can be executed by a first communication device. In the present application, the "first communication device" can refer to a communication device (e.g., a data storage network element), a component (e.g., a processor, a chip, or a chip system) in the communication device, or a logic module or software capable of implementing all or part of the functions of the communication device. For example, in the method provided in the first aspect, the data storage network element receives a first request message, the first request message including a label of requested first perception data, the label corresponding to characteristic information of the first perception data; acquires the first perception data from the perception data stored in the data storage network element according to the label; and sends the first perception data.

[0008] In the above method, the first request message carries the label of the requested first perception data, and then the data storage network element can acquire the first perception data according to the label of the first perception data and send the first perception data to the perception request network element. In this way, by introducing the label of the perception data, the perception data is easier to manage and access, and it is convenient to accurately and efficiently provide the perception data to the perception request network element.

[0009] In a possible design, the label is used to indicate the storage location of the first perception data.

[0010] In this way, since the label is used to indicate the storage location of the first perception data, the data storage network element can quickly determine the storage location of the first perception data, and it is convenient to quickly acquire the first perception data.

[0011] In a possible design, the label is a pointer used to indicate the storage location of the first perception data. The label can have various forms, such as a bit map form. For example, the bit map includes 12 bits, and the label of the first perception data is 000000000001.

[0012] In a possible design, the first request message further includes the generation time of the first perception data; and the acquiring of the first perception data from the perception data stored in the data storage network element according to the label includes: acquiring the first perception data from the perception data stored in the data storage network element according to the label and the generation time.

[0013] In this way, the first perception data can be acquired according to the label and other possible information (e.g., the generation time), so as to facilitate more accurate provision of the perception data to the perception request network element.

[0014] In a possible design, the feature information of the first perception data includes feature values of at least one feature dimension, and the at least one feature dimension includes at least one of the following: an industry type to which the first perception data belongs; a scene type to which the first perception data belongs; a content type of the first perception data; a spatial position corresponding to the first perception data; a data level of the first perception data; and a generation time of the first perception data.

[0015] In this way, the label of the perception data can correspond to the feature values of the plurality of feature dimensions of the perception data, so that the perception data can be more accurately obtained according to the label.

[0016] In a possible design, the method further includes: receiving or generating the first perception data; determining the label according to the feature information of the first perception data and a label generation rule, where the label generation rule is used to indicate that the feature information of the first perception data corresponds to the label; and storing the first perception data in a storage location indicated by the label.

[0017] In this way, the data storage network element stores the perception data according to the label of the perception data, so that the perception data is more easily managed and accessed.

[0018] In a possible design, the feature information of the first perception data includes feature values of at least one feature dimension; and the label generation rule is used to indicate that the feature information of the first perception data corresponds to the label, including: the label generation rule is used to indicate that the feature values of the at least one feature dimension correspond to at least one sub-label one by one, and the at least one sub-label is used to generate the label.

[0019] For example, the at least one feature dimension includes feature dimension 1 and feature dimension 2, and the at least one sub-label includes sub-label 1 and sub-label 2. The feature value of the feature dimension 1 included in the feature information of the first perception data is feature value a, and the feature value a of the feature dimension 1 corresponds to the sub-label 1. The feature value of the feature dimension 2 included in the feature information of the first perception data is feature value b, and the feature value b of the feature dimension 2 corresponds to the sub-label 2. For example, the feature dimension 1 is an industry type, the industry type to which the first perception data belongs is “traffic” (i.e., the feature value a of the feature dimension 1 is “traffic”), and the sub-label corresponding to “traffic” is 00 (i.e., the sub-label 1 is 00). Alternatively, the industry type to which the first perception data belongs is “drone” (i.e., the feature value a of the feature dimension 1 is “drone”), and the sub-label corresponding to “drone” is 01 (i.e., the sub-label 1 is 01).

[0020] In a possible design, the label generation rule is further used to indicate a generation manner of generating the label according to the at least one sub-label.

[0021] For example, the generating manner is to combine the at least one sub-label in a first order to obtain the label of the first perception data. In the above example, the first order is: sub-label 1, sub-label 2, and if sub-label 1 is 00 and sub-label 2 is 111, the label of the first perception data is 00111.

[0077] A (wireless) access network device is deployed in a (wireless) access network for connecting terminal devices to a wireless network. The (wireless) access network device can be generally connected to a core network through a wired link (e.g., fiber cable). The (wireless) access network device can also be referred to as a network device, a RAN device / node, which is hereinafter taken as an example for description. In embodiments of the present application, the network device can send a sensing signal and can also receive a sensing signal.

[0083] (4) Data network

[0084] The data network can also be referred to as a packet data network (PDN), which is a network outside the operator network. The operator network can access multiple DN, and the DN can deploy application servers corresponding to various services to provide various possible services for the terminal device. In actual communication, the client is usually located in the terminal device, and the server is usually located in the data network. The data network can be a private network such as a local area network, an external network not controlled by the operator such as the Internet, or a dedicated network jointly deployed by the operator, and the specific type is not limited.

[0085] FIG. 2 is a more specific network architecture diagram applicable to the embodiments of the present application, which is the network architecture of a 5G communication system. As shown in FIG. 2, the network architecture includes a terminal device, a network device, various types of core network elements / functions, and a data network.

[0086] The core network user plane includes a user plane function (UPF) network element.

[0087] The UPF network element is mainly responsible for connecting external networks and performing user data packet forwarding according to routing rules of the SMF network element, such as sending uplink data to a data network or other UPF network elements, and sending downlink data to other UPF network elements or access network devices.

[0088] The AMF network element is mainly responsible for access management and mobility management of terminal devices, such as maintaining the state of terminal devices, managing the reachability of terminal devices, forwarding mobility management non-access-stratum (MM NAS) messages, and forwarding session management (SM) N2 messages.

[0089] The SMF network element is mainly responsible for session management in a mobile network, including establishing a session for a terminal device, allocating and releasing resources for the session, wherein the resources include session quality of service (QoS), session path, and forwarding rules. For example, allocating an internet protocol (IP) address for a terminal device, and selecting a UPF network element that provides message forwarding functions.

[0090] The AUSF network element is mainly responsible for performing security authentication of terminal devices.

[0091] The NEF network element is used to interact between other internal network elements of the core network and external application servers of the core network, to provide network capability information to external application servers, or to provide information of external application servers to core network elements.

[0092] The NRF network element is mainly responsible for providing a storage function and a selection function of network function entity information for other network elements.

[0094] The UDM network element is mainly responsible for managing and controlling data. For example, the UDM network element can manage subscription information of a user, including obtaining subscription information and providing the same to other network elements (for example, the AMF network element); and registering and maintaining a network element currently serving a terminal device. The function of the UDM network element can be implemented through interaction with a unified data repository (UDR) network element (not shown in FIG. 2), which is used to store data required by the UDM network element to perform its operations. In actual implementation, the UDM network element and the UDR network element can be two independent physical entities, or the UDR network element can be integrated in the UDM network element, without limitation.

[0095] The AF network element is mainly responsible for providing service data of various applications to a control plane network element of a communication network of an operator, or obtaining data information and control information of the network from the control plane network element of the communication network.

[0096] Although not shown, other possible network elements, such as a location management function (LMF) network element, can also be included in the above network architecture, without limitation.

[0097] It can be understood that FIG. 2 is schematically shown by taking the core network control plane using a service-oriented architecture as an example. In the service-oriented architecture, each control plane network element is connected to a service bus, and the interaction between the control plane network elements adopts the form of service call, that is, the control plane network element opens services to other control plane network elements for calling. In other possible implementations, the core network control plane can also use a point-to-point communication mode, in which a specific set of messages exists between the communication interfaces of the control plane network elements. Among them, the interface between the terminal device and the AMF network element is called the N1 interface, the interface between the access network device and the AMF network element is called the N2 interface, the interface between the access network device and the UPF network element is called the N3 interface, the interface between the UPF network element and the SMF network element can be called the N4 interface, and the interface between the UPF network element and the data network is called the N6 interface. Of course, in the future communication system, the names of these interfaces can remain unchanged, or can be replaced by other names, and the present application does not limit this. In the future communication system, the above network elements or devices can still use their names in the 5G communication system, or have other names; the functions of the above network elements or devices can be completed by one independent network element, or by several network elements together, and the embodiments of the present application do not limit this.

Among them, there can be multiple data storage network elements, and the specific number of each network element is not limited by the embodiments of the present application. It can be understood that these network elements can also be deployed in a non-core network.

[0100] Data control network element: The data control network element includes a data orchestration network element, and optionally also includes a service orchestration network element. The data orchestration network element is responsible for the management of sensing data, and the service orchestration network element is responsible for the management of sensing services. The data control network element can be a newly added network element in the core network as shown in FIG. 2, such as the newly added network element (i.e. data control network element) which can communicate with other network elements in the core network through a service interface, or can also use a point-to-point communication mode to communicate with other network elements in the core network; or the data control network element can also be deployed in combination with the SF-C network element, such as deploying the function of the data control network element on the SF-C network element.

[0101] Data storage network element: responsible for storing sensing data, and optionally also responsible for calculating sensing data. The data storage network element can be a newly added network element in the core network as shown in FIG. 2, such as the newly added network element (i.e. data storage network element) which can communicate with other network elements in the core network through a service interface, or can also use a point-to-point communication mode to communicate with other network elements in the core network; or the data storage network element is an existing network element, such as the data storage network element can be at least one of the following: a terminal device (such as a terminal device as a sensing device, with the functions of sensing, calculating sensing data, storing sensing data, and transmitting sensing data), a network device (such as a network device as a sensing device, with the functions of sensing, calculating sensing data, storing sensing data, and transmitting sensing data), an SF-U network element, a UPF network element, a UDM network element, a UDR network element.

[0103] The network architecture and service scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. It can be known by those skilled in the art that, with the evolution of the communication system architecture and the appearance of new service scenarios, the technical solutions provided by the embodiments of the present application are also applicable to similar technical problems.

[0104] The related terms involved in the embodiments of the present application will be explained first. When not specifically explained, these explanations are to support the meaning of the related terms and make the embodiments of the present application easier to understand, and should not be regarded as a strict limitation on the related terms in the protection scope required by the present application.

[0105] (1) Perception

[0106] Perception can be understood as a technology capable of obtaining feature information of an environment and / or objects in the environment. Wireless signals (such as operator's 4.9G frequency band, 26G frequency band, 28G frequency band, etc.) have corresponding perception capabilities, and can perform perception identification on specific areas / objects / events, etc.

[0107] Among them, the implementation of perception is similar to the principle of radar, that is, the sending end (or transmitter) transmits electromagnetic waves (i.e., perception signals), the electromagnetic waves are reflected by the object to be perceived, and then obtained by the receiving end, and the receiving end (or receiver) can further process the obtained reflection signals (or called echo signals) to obtain perception data, which can be used to obtain perception results.

[0108] For example, when the base station is the sensing device, FIG. 3 is a schematic diagram of the base station performing the sensing operation. The base station shown in FIG. 3 can multiplex the electromagnetic wave signal of the communication system to perform sensing. The resources used by the base station for communication and the resources used by the base station for sensing can be time-division multiplexed (as shown in FIG. 3) or space-division multiplexed. The base station can use the electromagnetic wave signal to perform sensing detection, and can also receive the signal (which can be referred to as a reflected signal or echo signal) emitted back after the signal reaches the obstacle (i.e., the detected target), and obtain sensing data according to the echo signal. As shown in FIG. 3, the base station can perform serial-to-parallel conversion, phase shift keying, inverse fast Fourier transform (IFFT), parallel-to-serial conversion, digital-to-analog conversion, etc. on the to-be-transmitted signal, and the base station can also perform analog-to-digital conversion, parallel-to-serial conversion, fast Fourier transform, serial-to-parallel conversion, demodulation, etc. on the received echo signal. The to-be-transmitted signal can also be transmitted to a radar processor, so that the radar processor obtains sensing data according to the to-be-transmitted signal and the received echo signal (it can be understood that the echo signal here is the echo signal after the above processing). It should be understood that the processing of the to-be-transmitted signal and the received echo signal by the base station shown in FIG. 3 is only an example and should not constitute any limitation on the present application.

[0109] The sensing device in the wireless communication system can identify the specified area, the specified object or the event, and meet the sensing demand in traffic, unmanned aerial vehicle (UAV), home health, weather monitoring and other aspects. Specific examples are as follows:

[0110] 1. Traffic

[0111] Scenario 1: Since the sensing distance of the vehicle itself is short or the non-line-of-sight (NLOS) path cannot be sensed, the wireless communication system can generate large-scale dynamic map information based on sensing.

[0112] Scenario 2: In the process of vehicle driving, a ghost head danger event such as a sudden appearance of a person or an object occurs, and the wireless communication system can identify the danger event based on sensing and notify the vehicle to perform an emergency operation.

[0113] Scenario 3: Vehicle automatic driving assistance, and the wireless communication system can generate a customized high-precision dynamic map based on sensing to assist the vehicle in automatic driving.

[0114] 2. Unmanned aerial vehicle

[0115] Scenario 1: Violation of driving, such as unmanned aerial vehicle driving off the route, and the wireless communication system can identify the unmanned aerial vehicle violation based on sensing and perform real-time warning / post-penalty.

[0116] Scenario 2: The UAV enters a no-fly zone (e.g., an airport), and the wireless communication system can identify the UAV based on sensing and perform real-time emergency handling.

[0117] ③Home health

[0118] Scenario 1: Abnormal posture detection such as a person falling, and the wireless communication system can identify the abnormal posture based on sensing and alarm.

[0119] Scenario 2: Health detection such as human respiration / heartbeat, and the wireless communication system can identify abnormal indicators based on sensing and alarm.

[0120] ④Weather monitoring

[0121] The wireless communication system can perform sensing detection or prediction on the environment, climate, and weather changes.

[0122] FIG. 4 is a diagram of parameters affecting sensing accuracy and resolution. FIG. 4 takes the vehicle networking scenario as an example to show several parameters affecting sensing, including sensing positioning accuracy (including vertical and horizontal), sensing speed accuracy (including vertical and horizontal), and sensing resolution (including area and speed).

[0123] ①Distance resolution a: the ability to distinguish adjacent targets in distance, usually measured by the minimum resolvable distance interval, used to identify different vehicles.

[0124] ②Speed resolution b: the ability to distinguish targets in radial speed.

[0125] ③Angle measurement accuracy q: the ability of radar to distinguish adjacent targets in angle, usually measured by the minimum resolvable angle.

[0126] ④Horizontal field of view (FOV): the FOV shown in FIG. 4 is 120°, and under the 120° FOV, the bidirectional blind area range of a bidirectional road with a width of 30 meters is less than 18 meters, and the blind area area ratio is <1%.

[0127] (2) Sensing mode

[0128] The sensing mode is divided into double-base sensing mode and single-base sensing mode. Among them, double-base sensing includes two sensing devices (or sensing nodes, the sensing devices and sensing nodes involved in the text can be replaced equally), one sensing device transmits a sensing signal, which is reflected by a sensing target, and the other sensing device receives the sensing signal. Single-base sensing includes one sensing device, which transmits a sensing signal, which is reflected by a sensing target, and the sensing device receives the sensing signal.

[0129] The schematic diagram of double-base perception can be understood with reference to FIG. 5. FIG. 5(a) shows that the perception target in the perception area is a car, the perception device that transmits a signal is a base station, and the perception device that receives a signal is a UE. After the base station transmits a signal, the signal is reflected by the car to obtain a reflected signal, and the reflected signal is received by the UE. FIG. 5(b) shows that the perception target in the perception area is a car, the perception device that transmits a signal is a UE, and the perception device that receives a signal is a base station. After the UE transmits a signal, the signal is reflected by the car to obtain a reflected signal, and the reflected signal is received by the base station. FIG. 5(c) shows that the perception target in the perception area is a car, the perception device that transmits a signal is a base station 1, and the perception device that receives a signal is a base station 2. After the base station 1 transmits a signal, the signal is reflected by the car to obtain a reflected signal, and the reflected signal is received by the base station 2. FIG. 5(d) shows that the perception target in the perception area is a car, the perception device that transmits a signal is a UE 1, and the perception device that receives a signal is a UE 2. After the UE 1 transmits a signal, the signal is reflected by the car to obtain a reflected signal, and the reflected signal is received by the UE 2. The double-base perception shown in FIG. 5(a) and (b) will be described below as an example.

[0130] The schematic diagram of single-base perception can be understood with reference to FIG. 6. FIG. 6(a) shows that the perception target in the perception area is a car, and the perception device is a base station. After the base station transmits a signal, the signal is reflected by the car to obtain a reflected signal, and the reflected signal is received by the base station again. FIG. 6(b) shows that the perception target in the perception area is a car, and the perception device is a UE. After the UE transmits a signal, the signal is reflected by the car to obtain a reflected signal, and the reflected signal is received by the UE again.

[0131] (3) Perception data

[0132] The perception data in the embodiments of the present application can include at least one of raw perception data, intermediate processing data, basic object data, and service content data.

[0133] The raw perception data can include channel response information of an echo signal, such as at least one of amplitude data, phase data, in-phase (I) data, and quadrature (Q) data determined according to the echo signal.

[0134] The intermediate processing data can include data obtained after processing the echo signal. The processing of the echo signal involves multiple links, and the data obtained by each processing link can be referred to as intermediate processing data. For example, the intermediate processing data includes but is not limited to one or more of the following: in-phase quadrature (IQ) data, range Doppler (RD) spectrum, range Doppler angle (RDA) spectrum, distance / velocity (DV) spectrum, distance / velocity / angle (DVA) spectrum, range / velocity (RV) spectrum, range / velocity / angle (RVA) spectrum, a set of coordinate points, a point cloud, a point cluster, a cluster trace, and the like.

[0135] The basic object data includes data obtained by calculating and analyzing the intermediate processing data, which can also be referred to as a perception result. For example, the basic object data includes but is not limited to one or more of the following: the type, size, contour, position, movement path, speed, distance, angle, orientation, acceleration, and the like of an object.

[0136] The business content data includes data related to a business function obtained by analyzing the basic object data. For example, the business content data includes but is not limited to one or more of the following: data for autonomous driving, whether there is illegal occupation of a road, whether there is a lane speed, whether a collision warning is given, x intersection congestion, y location on z highway has fallen rocks, and the like.

[0137] Based on the above introduction, FIG. 7 illustrates a possible implementation of a perception service. As shown in FIG. 7, the SF network element can obtain a perception requirement from a perception request network element, which can be an AF network element, an external application server (AS), or a terminal device. After obtaining the perception requirement, the SF network element can control the execution object of the perception service to detect and / or collect the perception data. The execution object of the perception service can include one or more network devices and / or one or more terminal devices.

[0138] Taking the network device as an example, the network device can perform a perception operation to obtain perception data, which can include, for example, transmitting a perception signal and receiving an echo signal. After obtaining the perception data, the network device can send the perception data to the SF network element, and then the SF network element provides the perception data to the perception request network element. The SF network element can process the received perception data and provide the processed perception data to the perception request network element, or can directly provide the received perception data to the perception request network element, without limitation.

[0139] In the implementation shown in FIG. 7, the perception device (such as a network device) is to directly open the perception data to the perception request network element. Considering that the perception data needs to be reasonably managed and opened, a possible solution is to first store the obtained perception data in a data storage network element, and then provide the perception data to the perception request network element based on the request of the perception request network element after the data storage network element receives the request. However, since the perception is the detection of the objective physical world, the raw perception data generated contains rich and diverse information, and the processing of the raw perception data is relatively complex, and a large amount of calculation power will bring a large processing delay; therefore, if the data storage network element only stores the raw perception data without fine processing and storage, it will lead to that after receiving the request of the perception request network element, the data storage network element can only roughly obtain the stored raw perception data and perform corresponding data processing to obtain the perception data requested by the perception request network element, thereby causing poor accuracy and low efficiency of obtaining the perception data. Therefore, on the basis of being able to generate various perception data (such as the intermediate processing data, the perception result, the service content data and the like in the above) from the raw perception data, how to accurately and efficiently provide the perception data to the perception request network element still needs further research.

[0140] Based on this, the embodiment of the present application provides a communication method, device and system, which introduces the label of the perception data to accurately and efficiently provide the perception data to the perception request network element.

[0141] The communication method provided by the embodiment of the present application involves multiple communication devices, such as a first communication device, a second communication device and a third communication device. Among them, the first communication device is a data storage network element or a component in the data storage network element, such as a chip or a chip system arranged in the data storage network element. The second communication device is a perception request network element (such as AF, a terminal device or an application server) or a component in the perception request network element, such as a chip or a chip system arranged in the perception request network element; the third communication device is a data control network element or a component in the data control network element, such as a chip or a chip system arranged in the data control network element; the embodiment of the present application takes "the first communication device is a data storage network element, the second communication device is a perception request network element, and the third communication device is a data control network element" as an example for description.

[0142] It can be understood that, in the embodiments of the present application, "A sends information a / message a to B" can mean that A is the sending end of the information a / message a, and B is the receiving end of the information a / message a. The information a / message a can be forwarded or processed by other intermediate nodes, for example, A sends the information a / message a to C, and C forwards the information a / message a to B. The message name sent by A to C and the message name sent by C to B can be the same or different, and the specific implementation is not limited. "B receives information / message from A" can mean that A is the sending end of the information / message, and B is the receiving end of the information / message. The information / message can be forwarded or processed by other intermediate nodes, and the specific implementation is not limited.

[0143] The communication method provided by the present application will be described below in combination with specific embodiments.

[0144] FIG. 8 is a flowchart of a communication method provided by an embodiment of the present application. As shown in FIG. 8, the flowchart can include the following steps.

[0145] S801, a sensing request network element or a data control network element sends a first request message to a data storage network element, the first request message including a label of requested first sensing data, the label corresponding to characteristic information of the first sensing data; correspondingly, the data storage network element receives the first request message.

[0146] The "label of the first sensing data corresponding to the characteristic information of the first sensing data" can be understood as: the label of the first sensing data is associated with the characteristic information of the first sensing data. For example, the label of the first sensing data is obtained according to the characteristic information of the first sensing data. Exemplarily, taking sensing data a and sensing data b as an example, if the characteristic information of the sensing data a is different from the characteristic information of the sensing data b, the label of the sensing data a is different from the label of the sensing data b; if the characteristic information of the sensing data a is the same as the characteristic information of the sensing data b, the label of the sensing data a is the same as the label of the sensing data b.

[0147] Exemplarily, the characteristic information of the first sensing data includes a characteristic value of at least one characteristic dimension. The at least one characteristic dimension includes at least one of the following: ① an industry type to which the first sensing data belongs; ② a scene type to which the first sensing data belongs; ③ a content type of the first sensing data; ④ a spatial position corresponding to the first sensing data; ⑤ a data level of the first sensing data; and ⑥ a generation time of the first sensing data. The characteristic dimensions can have a hierarchical relationship, for example, the next level of the "industry type" is the "scene type", and the next level of the "scene type" is the "content type". In addition, the characteristic value of the characteristic dimension can be hierarchical information.

[0148] For example: ① The characteristic value of the feature dimension of "industry type" can include: traffic, unmanned aerial vehicle, family health, meteorological monitoring, etc.

[0149] ② The characteristic value of the feature dimension of "scene type" can include: urban intersection scene (corresponding to the traffic industry), foreign object identification scene (corresponding to the unmanned aerial vehicle industry), abnormal posture detection scene (corresponding to the family health industry), weather change scene (corresponding to the meteorological monitoring industry), etc.

[0150] ③ The characteristic value of the feature dimension of "content type" can include: traffic flow (corresponding to the urban intersection scene), unmanned aerial vehicle entering the industrial park (corresponding to the unmanned aerial vehicle entering the no-fly zone scene), personnel falling (corresponding to the abnormal posture detection scene).

[0151] ④ The characteristic value of the feature dimension of "spatial location" can include: geographic location information (such as part or all of longitude and latitude, altitude, city, jurisdiction, angle, sector, etc.) or information used by an operator network to identify an area (such as part or all of cell information, tracking area information, etc.); For example, the characteristic value of "spatial location" is: China - Beijing - Haidian District - X place, that is, the characteristic value of "spatial location" can be hierarchical information.

[0152] ⑤ The characteristic value of the feature dimension of "data level" can include: raw perception data, intermediate processing data (such as RV spectrum / RVA spectrum, point cloud information), perception results (such as the type, size, outline, position, path, speed of an object, etc.), business content data (such as x intersection congestion, z location has fallen stone on y highway).

[0153] ⑥ The characteristic value of the feature dimension of "generation time" can include: date / hour / minute / second / millisecond / microsecond, etc.; For example, the characteristic value of "generation time" is: September 10, 2024 12:10:10 10 milliseconds, that is, the characteristic value of "generation time" can be hierarchical information.

[0154] S802, the data storage network element acquires the first perception data from the perception data stored by the data storage network element according to the label of the first perception data.

[0155] Exemplarily, the data storage network element can pre-store the first perception data, and then after receiving the first request message, the data storage network element can acquire the first perception data from the stored perception data according to the tag of the first perception data carried in the first request message. The first perception data can be perception data generated by the data storage network element (for example, the first perception data is service content data obtained by the data storage network element through calculation and analysis), or can also be perception data received by the data storage network element from other devices / network elements (for example, the first perception data is perception data received by the data storage network element from a network device or a terminal device), and the specific implementation is not limited.

[0156] (1) The specific implementation of "storing the first perception data" is described.

[0157] Exemplarily, the data storage network element determines the tag of the first perception data according to the characteristic information of the first perception data and a tag generation rule, the tag of the first perception data is used to indicate the storage location of the first perception data, and then the data storage network element stores the first perception data in the storage location indicated by the tag. The tag can be understood as a pointer used to indicate the storage location of the first perception data. The form of the tag is various, for example, the tag can be in the form of a bitmap, for example, the bitmap includes 12 bits, and the tag of the first perception data is 000000000001.

[0158] The tag generation rule is used to indicate the correspondence between the characteristic information of the first perception data and the tag. The tag generation rule can be generated by the data storage network element, or can also be generated by the data control network element and sent to the data storage network element, and the specific implementation is not limited. The tag generation rule is described below by taking the implementation mode 1 and the implementation mode 2 as examples.

[0159] Implementation mode 1: The tag generation rule is used to indicate the correspondence between the characteristic value of at least one characteristic dimension of the first perception data and the tag. Referring to Table 1, it is an example of a possible tag generation rule.

[0160] Table 1: Example of tag generation rule

[0161] According to Table 1, assuming that the industry type to which the first perception data belongs is the traffic industry, the scene type to which the first perception data belongs is the urban intersection scene, the content type of the first perception data is the vehicle flow, the spatial location is China-Beijing-Haidian District-X place, the data level is the business content data, and the time information is September 10, 2024, 12:10:10, the label of the first perception data is 000000000001. Assuming that the industry type to which the first perception data belongs is the traffic industry, the scene type to which the first perception data belongs is the urban intersection, the content type of the first perception data is the vehicle position path, the spatial location is China-Beijing-Haidian District-X place, the data level is the perception result, and the time information is September 10, 2024, 12:10:10, the label of the first perception data is 000000000010. Other examples are not listed one by one.

[0162] Implementation 2: The label generation rule is used to indicate that the feature values of at least one feature dimension of the first perception data are in one-to-one correspondence with at least one sub-label, and the at least one sub-label is used to generate the label of the first perception data. Wherein, the sub-label can also be called a feature code, or other possible names, which are not limited in specific. There are many forms of sub-labels, for example, the sub-label can be in the form of a bit map, for example, the bit map includes 2 bits. The number of bits included in the sub-label corresponding to different feature dimensions can be the same, or can be different, for example, the sub-label corresponding to the industry type includes 2 bits, the sub-label corresponding to the scene type includes 2 bits or 4 bits, which are not limited in specific.

[0163] Optionally, the label generation rule is also used to indicate the generation manner of generating the label of the first perception data according to the at least one sub-label, for example, the generation manner is to combine the at least one sub-label in a first order to obtain the label of the first perception data, for example, the first order can refer to: the sub-label corresponding to the industry type, the sub-label corresponding to the scene type, the sub-label corresponding to the content type, the sub-label corresponding to the spatial location, the sub-label corresponding to the data level, and the sub-label corresponding to the generation time.

[0164] Referring to Table 2, for a possible label generation rule example.

[0165] Table 2: Label generation rule example

[0166] According to Table 2, assuming that the industry type to which the first perception data belongs is the traffic industry (the sub-label corresponding to the traffic industry is 00), the scene type to which the first perception data belongs is the urban intersection scene (the sub-label corresponding to the urban intersection scene is 00), the content type is the traffic flow (the sub-label corresponding to the traffic flow is 00), the spatial location is China-Beijing-Haidian District-X place (the sub-label corresponding to China-Beijing-Haidian District-X place is 00), the data level is the business content data (the sub-label corresponding to the business content data is 00), and the time information is September 10, 2024, 12:10:10 (the sub-label corresponding to September 10, 2024, 12:10:10 is 01), six sub-labels can be obtained, and then a label of the first perception data is generated according to the six sub-labels, for example, the label of the first perception data is 000000000001 obtained by combining the six sub-labels in the first order. Assuming that the industry type to which the first perception data belongs is the traffic industry (the sub-label corresponding to the traffic industry is 00), the scene type to which the first perception data belongs is the urban intersection scene (the sub-label corresponding to the urban intersection scene is 00), the content type is the vehicle position path (the sub-label corresponding to the vehicle position path is 01), the spatial location is China-Beijing-Haidian District-X place (the sub-label corresponding to China-Beijing-Haidian District-X place is 00), the data level is the perception result (the sub-label corresponding to the perception result is 01), and the time information is September 10, 2024, 12:10:10 (the sub-label corresponding to September 10, 2024, 12:10:10 is 01), six sub-labels can be obtained, and then a label of the first perception data is generated according to the six sub-labels, for example, the label of the first perception data is 000001000101 obtained by combining the six sub-labels in the first order. Other examples are not listed one by one.

[0167] With reference to the foregoing implementation manner 1 or implementation manner 2: optionally, in the case where the label generation rule is generated by the data control network element, the label generation rule can further include storage node information corresponding to the feature information of the first perception data, as shown in Table 1 or Table 2. For example, if the data storage network element determines that the storage node corresponding to the feature information of the first perception data is the data storage network element itself, the label of the first perception data can be determined according to the feature information of the first perception data, and then the first perception data is stored in the storage location indicated by the label; if the data storage network element determines that the storage node corresponding to the feature information of the first perception data is another data storage network element, the first perception data can be sent to the other data storage network element.

[0168] The data control network element can obtain the storage capability information of the plurality of data storage network elements (for example, the plurality of data storage network elements send the storage capability information to the data control network element), and then determine the correspondence between the feature information of the perception data and the storage node according to the storage capability information of the plurality of data storage network elements. The storage capability information can include at least one of the following: storage space size, reading delay, storage delay, and can also include other possible information, which is not limited in detail.

[0169] (2) The specific implementation of "obtaining the first perception data" is described.

[0170] Exemplarily, the data storage network element can obtain the first perception data from the storage location indicated by the label.

[0171] As a possible implementation, the feature information of the first perception data corresponding to the label of the first perception data includes the feature values of the above-mentioned 6 feature dimensions, and the perception data stored in the storage location indicated by the label of the first perception data is the first perception data. In this case, the data storage network element can obtain the first perception data according to the label of the first perception data.

[0172] As another possible implementation, the feature information of the first perception data corresponding to the label of the first perception data includes the feature values of part of the above-mentioned 6 feature dimensions, and the perception data stored in the storage location indicated by the label of the first perception data includes the first perception data and other perception data. In this case, the data storage network element can obtain the first perception data according to the label of the first perception data and other information.

[0173] For example, the feature information of the first perception data corresponding to the label of the first perception data includes the feature values of the above-mentioned feature dimensions ① to ⑤, the perception data stored in the storage location indicated by the label of the first perception data includes the first perception data and the second perception data, the feature values of the feature dimensions ① to ⑤ of the first perception data and the second perception data are the same, but the generation times are different. The first request message further includes the generation time of the requested first perception data, and then the data storage network element can obtain the first perception data according to the label of the first perception data and the generation time of the first perception data; specifically, the data storage network element determines the storage location indicated by the label according to the label of the first perception data, and then obtains the first perception data from the storage location according to the generation time of the first perception data.

[0174] It should be understood that the label of the first perception data in the embodiments of the present application is used to indicate the storage location of the first perception data, which means that there is an association or conversion relationship between the label of the first perception data and the storage location. For example, the label of the first perception data is A, and A is used as the input of a certain algorithm / model, and then the storage location of the first perception data can be output.

[0175] S803, the data storage network element sends the first perception data to the perception request network element or the data control network element; correspondingly, the perception request network element or the data control network element receives the first perception data.

[0176] Exemplarily, after receiving the first perception data, the data control network element can send the first perception data to the perception request network element.

[0177] By using the above method, since the first request message carries the label of the requested first perception data, the data storage network element can obtain the first perception data according to the label of the first perception data and send it to the perception request network element (or send it to the data control network element, which forwards it to the perception request network element). In this way, by introducing the label of the perception data, the perception data is easier to manage and access, and it is convenient to accurately and efficiently provide the perception data to the perception request network element.

[0178] Based on the introduction of FIG. 8, some more specific implementation processes are described below in combination with scenarios 1 to 6.

[0179] (1) Scenario 1: The data control network element generates a label generation rule and sends the label generation rule to the data storage network element; the perception request network element can obtain the label.

[0183] Exemplarily, there can be multiple data storage network elements, and the data control network element can send the label generation rule to each of the multiple data storage network elements. The embodiment of the present application is described by taking one of the data storage network elements as an example.

[0184] S903, after the data storage network element generates the first sensing data or receives the first sensing data, the data storage network element determines the label of the first sensing data according to the characteristic information of the first sensing data and the label generation rule, and stores the first sensing data in the storage location indicated by the label.

[0186] The data requirement information is used to determine the characteristic information of the requested first sensing data.

[0187] S905, the data control network element sends a response of the second request message to the sensing request network element, the response of the second request message including the label of the first sensing data; correspondingly, the sensing request network element receives the response of the second request message.

[0188] Taking the example of "the data control network element including the data orchestration network element and the service orchestration network element", the data control network element can determine the characteristic information of the requested first sensing data according to the data requirement information, and then determine the label of the first sensing data according to the characteristic information of the first sensing data and the label generation rule, and send a response of the second request message to the sensing request network element.

[0189] It can be understood that, if the data control network element includes the data orchestration network element but does not include the service orchestration network element, the data control network element can communicate with the sensing request network element through the service orchestration network element. For example, the above S904 and S905 can specifically include: step 1, the sensing request network element sends a second request message 1 to the service orchestration network element, the second request message 1 including data requirement information; step 2, the service orchestration network element determines the characteristic information of the requested first sensing data according to the data requirement information, and sends a second request message 2 to the data control network element, the second request message 2 including the characteristic information of the requested first sensing data; step 3, after the data control network element receives the second request message 2, the data control network element determines the label of the first sensing data according to the characteristic information of the first sensing data and the label generation rule, and sends a response of the second request message 2 to the service orchestration network element, the response of the second request message 2 including the label of the first sensing data; step 4, after the service orchestration network element receives the response of the second request message 2, the service orchestration network element sends a response of the second request message 1 to the sensing request network element, the response of the second request message 1 including the label of the first sensing data.

[0190] Optionally, the response of the second request message can also include first authorization credential information, and the specific generation manner of the first authorization credential information is not limited in the embodiments of the present application.

[0191] S906, the data control network element sends an authorization notification message to the data storage network element; correspondingly, the data storage network element receives the authorization notification message.

Optionally, the authorization notification message further comprises the label of the first sensing data, in which case, the authorization notification message indicates that the data storage network element is authorized to provide the specific sensing data (i.e. the first sensing data) to the sensing request network element.

[0193] It can be understood that S906 is an optional step.

[0194] S907, the sensing request network element sends a first request message to the data storage network element, the first request message comprising the label of the requested first sensing data; correspondingly, the data storage network element receives the first request message.

[0197] S909, the data storage network element sends a response to the first request message to the sensing request network element, the response to the first request message comprising the first sensing data; correspondingly, the sensing request network element receives the response to the first request message.

[0198] Exemplarily, after receiving the first request message, the data storage network element can determine whether the authorization is passed (e.g. whether the sensing request network element is the sensing request network element authorized by the previously received authorization notification message, whether the second authorization credential information is consistent with the first authorization credential information, and whether the label carried by the first request message is the same as the label in the previously received authorization notification message), if the authorization is passed (the sensing request network element is the sensing request network element authorized by the previously received authorization notification message, the second authorization credential information is consistent with the first authorization credential information, and the label carried by the first request message is the same as the label in the previously received authorization notification message), the data storage network element acquires the first sensing data from the sensing data stored in the data storage network element according to the label of the first sensing data, and sends the first sensing data to the sensing request network element. Optionally, if the authorization is not passed, the data storage network element can refuse to provide the first sensing data to the sensing request network element.
