[0048] For ease of understanding, some of the contents involved in the embodiments of this application are described below:

[0049] Sensing and communication systems are usually designed separately and occupy different frequency bands. ISAC enables sensing and communication systems to share the same frequency band and hardware, improving frequency efficiency and reducing hardware costs. ISAC will become a key technology for future wireless communication systems to support many important application scenarios. Typical applications of ISAC include: navigation and obstacle avoidance for autonomous vehicles, indoor positioning and activity recognition based on WiFi, communication and sensing for unmanned aerial vehicles, extended reality (XR), radar and communication integration, etc. Each application has different requirements, limitations and regulatory issues. ISAC has attracted great research interest and attention from academia and industry.

[0050] ISAC achieves low-cost, integrated communication and perception capabilities through shared hardware and software-defined functions. Its key features include: a unified and simplified architecture; reconfigurable and scalable functions; and improved efficiency and reduced costs. The advantages of integrated communication and perception are threefold: reduced equipment cost and size; improved spectrum utilization; and enhanced system performance.

[0051] In the embodiments of the present application, typical communication perception integration scenarios that are expected to be achieved through technical upgrades of the communication system architecture are exemplified as shown in Table 1 below.

[0052] Table 1 Typical scenarios of communication perception integration

[0053] In the embodiments of the present application, the sensing signal is divided into six basic sensing modes according to the difference between the sensing signal sending node and the sensing signal receiving node, as shown in FIG2 (taking the base station as an example of the access network node), specifically including:

[0054] 1) Base station self-transmitting and self-receiving sensing: In this sensing mode, base station A sends a sensing signal and performs sensing measurement by receiving the echo of the sensing signal;

[0055] 2) Inter-base station air interface sensing: Base station B receives the sensing signal sent by base station A and performs sensing measurements;

[0056] 3) Uplink air interface perception: Base station A receives the perception signal sent by terminal A and performs perception measurement;

[0057] 4) Downlink air interface perception: Terminal B receives the perception signal sent by base station B and performs perception measurement;

[0058] 5) Terminal self-transmitting and self-receiving sensing: Terminal A sends a sensing signal and performs sensing measurement by receiving the echo of the sensing signal;

[0059] 6) Sidelink perception between terminals: Terminal B receives the perception signal sent by terminal A and performs perception measurement.

[0060] It's worth noting that each sensing method in Figure 2 uses one sensing signal transmitting node and one sensing signal receiving node as examples. In actual systems, one or more sensing methods can be selected based on different sensing use cases and requirements, and each sensing method can have one or more transmitting and receiving nodes. The sensing targets in Figure 2 use people and vehicles as examples, assuming neither person nor vehicle carries or has installed signal transceiver / receiver equipment. However, the sensing targets in actual scenarios will be much richer.

[0061] In the embodiments of the present application, the perception data (or perception information) includes at least one of a perception measurement report and perception assistance data. The perception measurement report primarily comprises measurement results obtained after measuring perception measurement quantities, while the perception assistance data includes the location of the terminal sending or receiving the perception signal, the location of the access network node sending or receiving the perception signal, an environmental map, target area information, and the like.

[0062] An optional classification method is to classify the perception measurement quantities into the following four categories (this description focuses on the measurement quantities, and can also be divided into three categories or unclassified, etc., and the four categories are only for illustration). Based on the relationship between the perception measurement quantities and the perception services, the third and fourth level measurement quantities below are generally also referred to as perception results. The measurement results of the second and / or first level measurement quantities are also referred to as perception measurement data.

[0063] a) First-level measurement quantities (received signal / original channel information), including: received signal / channel response complex results, amplitude / phase, I / Q channel and their operation results (operations include addition, subtraction, multiplication, and division, matrix addition, subtraction, multiplication, and division, matrix transposition, trigonometric operations, square root operations, and power operations, as well as threshold detection results and maximum / minimum value extraction results of the above operation results; operations also include Fast Fourier Transform (FFT) / Inverse Fast Fourier Transform (IFFT), Discrete Fourier Transform (DFT) / Inverse Discrete Fourier Transform (IDFT), 2-Dimensional FFT (2D-FFT), 3-Dimensional FFT (3D-FFT), matched filtering, autocorrelation operation, wavelet transform, and digital filtering, as well as threshold detection results and maximum / minimum value extraction results of the above operation results);

[0064] b) Second-level measurement quantities (basic measurement quantities), including: time delay, Doppler, angle, signal strength, and their multi-dimensional combination representation;

[0065] c) Level 3 measurements (basic attributes / status), including: distance, velocity, angle / direction, radar cross section (RCS), and acceleration;

[0066] d) Level 4 measurements (advanced attributes / states) include: spatial position, target presence, trajectory, movement, expression, vital signs, quantity, imaging results, weather, air quality, shape, material, and composition.

[0067] Optionally, the perception configuration includes at least one of the following:

[0068] Configuration of perception measurement objects, configuration of perception signals, configuration of perception measurement quantities, configuration of perception measurement reports and transmission configuration of perception data.

[0069] In the embodiment of the present application, the perception configuration (or perception configuration information) includes at least one of perception measurement object configuration information, perception signal configuration information, perception measurement quantity configuration, perception (measurement) report configuration, and perception data transmission configuration.

[0070] Wireless sensing is the process of measuring received signals and then processing the measurement results to obtain the desired sensing results. Therefore, the configuration of the sensing signal can also be called the configuration of the sensing measurement object, which includes at least one of the following:

[0071] Waveforms, such as Orthogonal Frequency Division Multiplexing (OFDM), Single Carrier Frequency Division Multiple Access (SC-FDMA), Orthogonal Time Frequency Space (OTFS), Frequency Modulated Continuous Wave (FMCW), and pulse signals;

[0072] Subcarrier spacing: For example, the subcarrier spacing of an OFDM system is 30 kHz.

[0073] Guard interval: The time interval between the end of a signal transmission and the reception of the latest echo signal of that signal. This parameter is proportional to the maximum sensing distance. For example, it can be calculated as 2dmax / c, where dmax is the maximum sensing distance (a sensing requirement). For example, for a self-transmitting and self-receiving sensing signal, dmax represents the maximum distance between the sensing signal receiving point and the signal transmitting point. In some cases, the cyclic prefix (CP) of the OFDM signal can serve as the minimum guard interval. c is the speed of light.

[0074] Bandwidth: This parameter is inversely proportional to the range resolution and can be obtained by c / 2 / delta_d, where delta_d is the range resolution (a perception requirement);

[0075] Burst duration: This parameter is inversely proportional to the rate resolution (a sensing requirement). It is the time span over which the signal is sensed, primarily for calculating Doppler shift. This parameter can be calculated as c / 2 / delta_v / fc, where delta_v is the rate resolution and fc is the carrier frequency or center frequency of the signal.

[0076] Time interval: This parameter can be calculated as c / 2 / fc / v_range; where v_range is the maximum rate minus the minimum rate (pertaining to the sensing requirement); this parameter is the time interval between two adjacent sensing signals;

[0077] The transmit power of the sensing signal is measured, for example, with a value of 2dBm intervals from -20dBm to 23dBm.

[0078] The port information of the sensing signal, including the number and port number;

[0079] Signal formats, such as the Channel-State-Information Reference Signal (CSI-RS), Sounding Reference Signal (SRS), Demodulation Reference Signal (DMRS), Positioning Reference Signal (PRS), or other predefined signals, as well as related sequence format information;

[0080] Signal direction; for example, the direction of the perceived signal (e.g., base station transmission and user equipment (UE) reception, base station reception and UE transmission, base station self-transmission and self-reception, base station-to-base station transmission and reception, UE self-transmission and self-reception, or UE-to-UE transmission and reception);

[0081] · Sense the beam information of the signal;

[0082] Time resources, such as the time slot index or symbol index of the time slot where the perception signal is located. There are two types of time resources: one-time time resources, for example, one symbol sends an omnidirectional first signal; and one-time time resources, for example, multiple groups of periodic time resources or discontinuous time resources (which may include a start time and an end time). Each group of periodic time resources sends a perception signal in the same direction, and different groups of periodic time resources have different beam directions.

[0083] Frequency resources, including the center frequency of the sensing signal, bandwidth, resource blocks (RBs) or subcarriers, etc.

[0084] Quasi Co-Location (QCL) relationship, for example, the sensing signal includes multiple resources, each resource is associated with a synchronization signal block (Synchronization Signal / PBCH Block, SSB) QCL, and the QCL includes Type A, B, C or D.

[0085] The sensing measurement parameters configuration is used to instruct the sensing measurement node to measure at least one of the following sensing measurement parameters (a three-category approach is exemplified below for the sensing measurement parameters):

[0086] a) First-level measurement quantities (received signal or original channel information), including: received signal / channel response complex results, amplitude / phase, I / Q path and operation results thereof (operations include addition, subtraction, multiplication, and division, matrix addition, subtraction, multiplication, and division, matrix transposition, trigonometric operations, square root operations, and power operations, as well as threshold detection results and maximum / minimum value extraction results of the above operation results; operations also include Fast Fourier Transform (FFT) / Inverse Fast Fourier Transform (IFFT), Discrete Fourier Transform (DFT) / Inverse Discrete Fourier Transform (IDFT), 2D-FFT, 3D-FFT, matched filtering, autocorrelation operation, wavelet transform, and digital filtering, as well as threshold detection results and maximum / minimum value extraction results of the above operation results);

[0087] b) Second-level measurement quantities (basic measurement quantities), including: time delay, Doppler, angle, signal strength, and their multi-dimensional combination representation;

[0088] c) Level 3 measurements (also known as perception results) include: target presence, distance, speed, angle / direction, RCS, acceleration, position, trajectory, movement, expression, breathing rate, heart rate, imaging results, weather, air quality, material and composition, etc.

[0089] The perception measurement report configuration includes at least one of the following:

[0090] The access type used for report transmission is indicated, which can be 3rd Generation Partnership Project (3GPP) access or non-3GPP access. Further, 3GPP access can be indicated as the 4th Generation (4G) (LTE), the 5th Generation (5G) (NR), 6G, etc., and non-3GPP can be indicated as Wireless Local Area Network (WLAN), Bluetooth, and wired network, etc. If there are multiple access types, the priority order can also be reflected through a list. For example, if the access type used for report transmission is indicated as 5G or 4G, it means that 5G is used to transmit the report first.

[0091] Reporting criteria: The criteria that triggers the sensing measurement node to send measurement reports, which can be periodic, event-triggered, or indicated. Events include but are not limited to the following:

[0092] The perceived signal quality detected by the receiving end meets the threshold requirements, such as at least one of the following: the signal-to-noise ratio (SNR), the reference signal receiving power (RSRP), the received signal strength indication (RSSI), and the signal-to-clutter ratio threshold. If the threshold is met, the perceived measurement quantity in the perception measurement item configuration is measured and reported.

[0093] The perception measurement results obtained by the receiving end meet the perception requirements, that is, the perception performance indicators corresponding to the calculated perception measurement results meet or exceed the preset threshold. For example, the perception SNR (which can be optionally defined as the ratio of the effective signal power of the signal propagation path corresponding to the perception target to the noise power, or defined as the ratio of the effective signal power of the signal propagation path corresponding to the perception target to the sum of the noise power and the signal power of the signal propagation paths corresponding to non-perception targets) is or exceed the preset threshold.

[0094] The receiving end correctly demodulates the data (e.g., passes a cyclic redundancy check (CRC) check) and performs perception based on the communication data, using a method of first demodulating and then estimating the perception parameters. If the communication demodulation is incorrect, the perception measurement results will be affected and become unreliable.

[0095] The mandatory sensing measurement items meet the requirements. For example, the latency, Doppler and Global Positioning System (GPS) location information of the sensing signal are mandatory sensing measurement items, while RSRP and Reference Signal Receiving Quality (RSRQ) are optional. In this case, they are reported only when multiple mandatory sensing measurement items are available.

[0096] Report format: The report includes the maximum number of cells under the Radio Access Technology (RAT) supported by the second node, the maximum number of measurement quantities for each cell, etc.

[0097] In the embodiment of the present application, the above-mentioned perception data transmission configuration can be understood as a transmission-related configuration of a type of data.

[0098] In the embodiment of the present application, the perceived service quality (QoS) is used to indicate the requirement for the perceived service quality. It can be defined in at least one of the following ways:

[0099] Perception QoS classes are categorized as Type I: Best Effort. If the perception data fails to meet the QoS requirements, the perception data must still be fed back, but with an indication that the requested QoS was not met. If no perception data is obtained, the reason for the failure is fed back. Type II: Multiple QoS. This includes QoS requirements corresponding to multiple QoS levels. If the perception data fails to meet the most stringent QoS requirements, the Sensing Function (SF) initiates the perception process again, attempting to meet lower QoS requirements until one of the QoS requirements is met. If the most relaxed QoS requirements are still not met, the positioning result is not fed back, only the reason for the failure is fed back. Type III: Assured, the most stringent perception QoS type. If the perception data fails to meet the QoS requirements, the positioning result is not fed back, only the reason for the failure is fed back.

[0100] Positioning accuracy (including horizontal and vertical accuracy) describes how closely the measured perception result (i.e., position) of a target object matches its true position. This can be further divided into horizontal perception accuracy and vertical perception accuracy. The former refers to the perception error on a two-dimensional reference plane or horizontal plane, while the latter refers to the perception error along the vertical axis or height.

[0101] Velocity accuracy (including horizontal accuracy and vertical accuracy): describes how close the measured perception of the target object's velocity (i.e., speed) is to its true velocity.

[0102] Perceptual resolution: describes the minimum difference in the measured magnitude (e.g., distance, velocity) of a target object to allow detection of objects of different magnitudes.

[0103] Refresh rate: describes the rate at which sensory data is generated. It is the inverse of the time interval between two consecutive sensory data.

[0104] Missed detection probability: describes the ratio of missed detection events to all events of obtaining sensing results within any predetermined time period when the system attempts to obtain sensing data. It is mainly applicable to binary judgment sensing data.

[0105] False alarm probability: describes the ratio of events that do not represent target objects or environmental features to all events detected in any predetermined time period when attempting to acquire sensory data. It is mainly applicable to perception data with binary judgments.

[0106] Recognition accuracy: describes the probability of correctly identifying the perceived target category.

[0107] Maximum perception service latency: describes the time between triggering the required perception data and providing the perception data at the perception system interface.

[0108] Optionally, the perceived QoS information includes at least one of the following:

[0109] Perception QoS type, positioning accuracy, speed accuracy, perception resolution, perception refresh rate, perception missed detection probability, perception false alarm probability, perception recognition accuracy, and maximum perception service delay.

[0110] Communication and perception fusion involves multiple devices, including the perception target, the perception area, the node sending the perception request, the perception node, and the node receiving the requested perception information. This poses privacy issues for perception services. This embodiment of the present application provides targeted authorization services for different perception requests, improving the privacy performance of perception services.

[0111] Below, in combination with the accompanying drawings, the perception service authorization, perception request method, device, terminal, equipment and medium provided by the embodiments of this application are described in detail through some embodiments and their application scenarios.

[0112] Referring to FIG3 , FIG3 is a flowchart of a method for authorizing a perception service provided in an embodiment of the present application, which is used for a second node. As shown in FIG3 , the method includes the following steps:

[0113] Step 301: The second node receives a first message sent by the first node, where the first message is used to sense the request.

[0114] In an embodiment of the present application, the first node initiates a perception request process by sending a first message to the second node. The above-mentioned perception request process is used to request perception, wherein the first message can also be described as a perception request or a perception request message.

[0115] The first node may be a terminal, a network function node (e.g., a core network function node or a radio access network node), or an application function or a perception service client. The second node may be a terminal, a network function node (e.g., a core network function node or a radio access network node), or an application function or a perception service client.

[0116] Step 302: The second node obtains a target-aware privacy profile corresponding to the first message.

[0117] In an embodiment of the present application, the first message is used for perception request, which can be understood as carrying information related to the perception request. The second node can determine the corresponding target perception privacy profile based on the first message and the target perception privacy profile corresponding to the first message, that is, based on the content of the first message (information related to the perception request).

[0118] Perception service authorization primarily involves authorization of the requested perception area, perception target, or perception service category. When the perception target is a terminal (UE), the perception target is a terminal-associated target, or the perception area is an area associated with a terminal, the perception service is more closely associated with the corresponding terminal or the terminal's corresponding user. Therefore, these types of perception requests require a better perception service authorization method to protect user privacy.

[0119] In the perception process corresponding to the delay perception request, since changes in the authorization information may be sent within the corresponding time, the authorization method for the delay perception request can be considered in the perception service authorization method.

[0120] In addition, for the same perception requesting node, the user and / or the network may also wish to differentiate different privacy requirements, for example, based on the perception service requested by the perception requesting node or the service provided to the user. The service provided by the perception requesting node to the user can also be expressed as the service type of the service provided by the requested perception service to the user. For example, the application function AF requests the perception service of motion recognition, and the perception service AF is used to provide gaming services to the user.

[0121] Optionally, the first message includes at least one of the following:

[0122] Perception request type, perception service type, perception target, perception area, sending node identifier of the perception signal, receiving node identifier of the perception signal, receiving node identifier of the requested perception data, requested perception data type indication, first node identifier, perception response timeliness indication, perception mode indication, perception service quality QoS information, valid duration of the requested perception data, pseudo-identification indication of the perception target, and perception integrity requirements.

[0123] In an embodiment of the present application, the first message includes the perception request type, and the first message may carry indication information indicating the perception request type.

[0124] Optionally, the perception request type includes at least one of the following:

[0125] Perception request where the perception target is a terminal, perception request where the perception target is associated with a terminal, perception request where the perception area is associated with a terminal, perception request where the perception target is non-terminal associated, perception request where the perception area is non-terminal associated, perception request where the perception target is an access network device, perception request where the perception target is associated with an access network device, perception request where the perception area is associated with an access network device, perception request where the perception target is associated with a non-access network device, perception request where the perception area is associated with a non-access network device, immediate perception request, delayed perception request, periodic perception request.

[0126] In an embodiment of the present application, the perception request type may adopt a standard perception request type, or a customized perception request type, or a combination of the two.

[0127] For sensing services, the sensing request type can be classified into at least one of the following types, depending on whether the sensing target is a UE / base station, or whether the sensing target and / or sensing area is associated with one or more UEs / base stations:

[0128] The perception target is a terminal and / or an access network node. The perception request includes a terminal (e.g., user equipment UE) as the perception target, for example, a request to perceive the speed or position of the target UE; and the perception target is an access network node, for example, a request to perceive the speed or position of a mobile base station (e.g., a base station deployed on a low-orbit satellite).

[0129] The target is a perception request for associated terminals and / or access network nodes: including the association of perception targets or perception areas with the above-mentioned terminals and / or access network nodes. One method can be represented by terminal / access network node identifiers and corresponding association conditions. For example, breathing monitoring of one or more people (for example, 2 people) closest to a UE, obstacle perception within 5 meters near a UE, environmental reconstruction within a range corresponding to a mobile base station (for example, a base station deployed on a low-orbit satellite) (for example, the perceptible range can be determined based on perception accuracy and base station power, etc.), and intrusion monitoring within a range corresponding to multiple cells or base stations in a private network scenario. Usually, this type of perception request needs to be perceived based on the location information of the terminal and / or access network node, especially when the associated terminal and / or access network node is mobile, it is necessary to first obtain the latest location information of the terminal and / or access network node, so the perception process definition can be defined for this type of feature.

[0130] Sensing requests targeting non-terminals and / or access network nodes include sensing requests where the sensing target or sensing area is a geographic area and sensing characteristics, such as drone intrusion monitoring within a geographic area represented by longitude, latitude, and altitude, or sensing vehicles with speeds exceeding a threshold using the sensing characteristic of speed. For general geographic area descriptions, refer to 3GPP TS 23.032.

[0131] For sensing services, based on the expected timeliness of the sensing response, the sensing request type can be classified into at least one of the following:

[0132] Immediate Location Request: The location requester expects to receive a response containing location information within a short period of time, where the time can be specified using the quality of service parameter Qos.

[0133] Deferred Sensing Request: The sensing requester expects to receive a response containing an indication of event occurrence and / or sensing data at a future time (or multiple times);

[0134] Periodic Sensing: A predefined periodic timer is used to activate the event of sensing reporting when the timer expires.

[0135] Optionally, the response to the delay-aware request is associated with at least one of the following:

[0136] Preset perception results, preset perception area, preset perception time, preset feature changes, terminal availability and network equipment availability.

[0137] The event type of the delay awareness request includes at least one of the following:

[0138] Interesting perception results (also known as pre-defined perception results): For example, in intrusion monitoring, the event type might be "intrusion occurred." Another example is rainfall monitoring, where the event type might be "heavy or light rainfall," and one or more pre-defined rainfall intervals.

[0139] Area (also described as a predefined sensing area): Detects events where a target enters, leaves, or stays within a predefined geographic area.

[0140] Preset perception time: After receiving a perception request, perception may not be performed immediately, but may be performed and perception data may be fed back at a preset time. In particular, the preset perception time may be periodic sensing, i.e., a predefined periodic timer, and an event of activating a perception report when the timer expires. In an embodiment of the present application, a periodic perception request may be used as a parallel perception request form with a delayed perception request, or may be used as a perception request form in a delayed perception request.

[0141] Interesting change features (also described as preset feature changes): For example, the event that the target moves more than a predefined straight-line distance from its previous location. Another example is the event that the rainfall in the sensing area changes by more than a predefined threshold from the previous time.

[0142] Availability of the terminal and / or network equipment: Any event in which network equipment (including core network nodes and / or radio access network nodes, such as AMFs and / or base stations) establishes contact with the terminal. This can also refer to any event in which the core network establishes contact with a radio access network node. For example, this refers to the core network reestablishing a connection with the UE after the UE enters flight mode or is powered off.

[0143] In the embodiments of the present application, for the convenience of explanation, base stations are used instead of access network nodes in some descriptions. It can be understood that the content of the base station can be replaced by other access network nodes.

[0144] Optionally, the perception service type includes at least one of the following: a requested perception service type, and a service type used by the requested perception service to provide a service.

[0145] In an embodiment of the present application, the service provided by the perception requesting node to the user can also be expressed as the service type of the requested perception service used to provide services to the user. For example, the application function AF requests the perception service of action recognition, and the perception service AF is used to provide game services to the user.

[0146] In an embodiment of the present application, one situation is that the perception request includes a perception service type, and another situation is that the perception request includes a perception service identifier. A perception service type includes one or more perception services (identifiers). Then, when the perception request includes a perception service identifier but does not include a service type, the perception service identifier (such as a game A) can be mapped to the perception service type (such as a game) to which the perception service identifier belongs. The perception service type can be classified based on the perception content or the perception service purpose, and each method has a corresponding perception service type. The service types described in the embodiment of the present application include service types classified by perception content, and / or service types classified by perception purpose.

[0279] Exemplarily, for public safety perception services, users should not refuse, so they are allowed by default and authorized; for auxiliary communication perception services, one method is to allow by default, and one method is to allow by notification (that is, the network should send a notification to the user in the perception area); for at least one of motion monitoring, imaging detection, indoor target tracking, outdoor target tracking, indoor target detection and tracking, outdoor target detection and tracking, sleep monitoring, motion monitoring, fall detection, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, point cloud, imaging classification or imaging segmentation, one method is not allowed by default, one method is to allow by notification (that is, the network should send a notification to the user in the perception area), and one method is to allow by verification (that is, the network should send verification to the user in the perception area, allow if permission is received, or allow if permission is received / no response is received).

[0297] In the embodiment of the present application, the second node may directly determine the target-aware privacy profile according to a preset rule, or may obtain the target-aware privacy profile by interacting with other nodes.

[0298] Optionally, the second node obtains a target-aware privacy profile corresponding to the first message, including at least one of the following:

[0299] The second node determines a first awareness request type of the awareness request according to the first message, and obtains a target awareness privacy profile corresponding to the first awareness request type;

[0300] The second node determines, according to the first message, a third perception service type of the perception request, and obtains a target perception privacy profile corresponding to the third perception service type;

[0301] The second node determines a first perception area of ​​the perception request according to the first message, and obtains a target perception privacy profile corresponding to the first perception area.

[0302] In an embodiment of the present application, at least one of the perception request type, perception service type and perception area corresponding to the perception request is determined based on the first message, the corresponding target perception privacy profile is determined, and then targeted perception privacy configuration is performed.

[0303] Optionally, the second node obtains a perception privacy profile, where the perception privacy profile includes at least one of a UE perception privacy profile, an access network device perception privacy profile, and a perception area privacy profile.

[0304] Optionally, obtaining the target-aware privacy profile corresponding to the first perception area includes at least one of the following:

[0305] In a case where the first perception area is a private area, obtaining the target perception privacy profile through a management device of the private area;

[0306] When the first perception area is a public area, obtaining the target perception privacy profile according to a preset rule;

[0307] In a case where the first perception area is a public area, the target perception privacy profile is obtained through a management device of the public area.

[0308] In the embodiment of the present application, when the perception areas are different types of areas, the corresponding target perception privacy profiles can be obtained through different methods or devices.

[0309] Optionally, the target perceptual privacy profile includes a first perceptual privacy profile and a second perceptual privacy profile; wherein, the first perceptual privacy profile is the perceptual privacy profile obtained by the second node after receiving the first message; and the second perceptual privacy profile is the perceptual privacy profile obtained by the second node after obtaining the first perceptual privacy profile.

[0310] In an embodiment of the present application, the second node may also update the obtained target perception privacy configuration. For example, in the perception process corresponding to the delayed perception request, since changes in the authorization information may be sent within the corresponding time, the authorization method for the delayed perception request also needs to be considered in the perception service authorization method. Optionally, the first perception privacy profile may be obtained at the request start node, and the updated perception privacy profile (second perception privacy profile) may be obtained at different subsequent time points. It can be understood that the second perception privacy profile may be multiple different perception privacy profiles obtained at multiple different time points.

[0311] For ease of understanding, the following examples illustrate the authorization process of the perception service involved in this application:

[0312] Example 1: Perception service authorization based on perception request type.

[0313] There are various types of sensing requests, depending on the sensing target, sensing area, the node sending the sensing request, whether the node sending the sensing request is a sensing node, the receiving node of the requested sensing information, the timeliness of the response, and the sensing information requested. When the sensing target is a UE, the sensing target is a target associated with the UE, or the sensing area is an area associated with the UE, the sensing service is more closely associated with the corresponding UE or the user corresponding to the UE. This embodiment uses the aforementioned two sensing request types, where the target is a UE base station sensing request and the target is an associated UE sensing request, as examples.

[0314] Step 1. The first node sends a perception request (first message). The content included in the perception request (first message) can refer to the description of the previous embodiment. In the embodiment of the present application, at least the perception request type can be determined based on the perception request (first message).

[0315] Step 2: The second node (such as AMF, NEF, SF, base station, etc.) receives the perception request and authorizes according to the perception request.

[0316] When the sensing type is a sensing request with a target UE or a sensing request with an associated UE, one authorization method is for the second node to obtain a sensing privacy profile corresponding to the sensing target UE, the UE associated with the sensing target, or the UE associated with the sensing area. Alternatively, when the first message does not include the sensing request type, the second node may determine, based on the sensing request information, and map the received sensing request to the sensing request type to which it belongs.

[0317] For example, the second node requests a third node (eg, UDM) to obtain a perception privacy profile corresponding to the perception target UE, the UE associated with the perception target, or the UE associated with the perception area. The perception privacy profile includes at least one of the following:

[0318] The first indication information is used to indicate whether sensing is allowed;

[0319] Validity period, such as a valid time interval represented by a start time and an end time, the validity period combined with the first indication information may indicate whether perception is allowed or not allowed within the validity period, i.e., indicating the validity period during which perception is allowed or not allowed;

[0320] The valid area, such as a general geographical area, or an area associated with the UE, base station, or AMF (such as an access network notification area (RAN Notification Area, RNA), a tracking area (Tracking Area, TA), etc.), can be combined with the first indication information to indicate whether sensing is allowed or not allowed within the valid area, that is, indicating the sensing area is allowed or not allowed;

[0321] Service type: The service type, in combination with the first indication information, may indicate whether perception of a certain service type is allowed or not allowed, that is, indicates the allowed service type or the disallowed service type;

[0322] Notify the perceived UE and allow perception;

[0323] Perception requires notification and verification of the end user, and is only allowed if the user agrees or no response is received;

[0324] Perception requires notification and verification of the end user, and perception is allowed only with user authorization;

[0325] The second node should also subscribe to changes in the UE-aware privacy profile. If the UE-aware privacy profile sends a change, the second node can obtain the updated UE-aware privacy profile. The second node performs authorization based on the UE's awareness implicit profile. Potential situations include at least one of the following:

[0326] If sensing is not allowed, then the authorization is rejected. The network (second node or other nodes) sends a sensing response to reject the sensing request.

[0327] If perception is allowed, authorization is passed and step 3 is executed.

[0328] When the perception request type is the delay perception service request described in the aforementioned embodiment, the second node needs to authorize based on the latest UE perception privacy profile at the beginning of the delay perception request and each time the perception data is responded to, to ensure the timeliness of the perception privacy profile, thereby better protecting user privacy.

[0329] Step 3: If the authorization is passed, the network selects the perception-related functional nodes (such as AMF, NEF, SF), the perception method, and the perception nodes (base station and / or UE).

[0330] Step 4: The selected node receives the sensing configuration information (see the description of the above embodiment) and executes the sensing process.

[0331] In step 5, the network (the second node or another node) optionally sends a perception response to the perception result receiving node indicated by the perception request. When the first node is a UE, and the UE is both the perception measurement node and the perception result receiving node, one method is: in step 4, the UE reports the perception measurement data to the network, and the network then sends the generated perception result to the UE in this step. Another method is: the UE generates a perception result based on the perception measurement data without reporting the perception test data to the network, and the perception measurement reporting in step 4 and step 5 are skipped.

[0332] Example 2: Awareness service authorization based on the awareness service type and / or awareness area.

[0333] This embodiment introduces the authorization of sensing services based on sensing service types and / or sensing areas. Because the authorization of sensing services may differ for different sensing types and / or sensing areas, for example, when the sensing service type is motion monitoring, imaging detection, indoor target tracking, outdoor target tracking, indoor target detection and tracking, outdoor target detection and tracking, sleep monitoring, motion monitoring, fall detection, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, point cloud, imaging classification, or imaging segmentation, the sensing service is more closely associated with users within the sensing area.

[0334] Step 1. The first node sends a perception request (first message). The content included in the perception request (first message) can refer to the description of the previous embodiment. In the embodiment of the present application, at least the perception service type and / or perception area can be determined based on the perception request (first message).

[0335] Step 2: The second node (such as AMF, NEF, SF, base station, etc.) receives the perception request and authorizes according to the perception request.

[0336] The second node performs authorization based on the perception service type. When the perception request contains a perception service identifier but does not include a service type, the second node maps the perception service identifier to the perception service type to which the perception service identifier belongs, and the second node obtains the corresponding perception privacy profile based on the perception service type; and / or, the second node obtains the perception privacy profile corresponding to the perception area.

[0337] If the perception area is a private area, then the perception privacy profile of the perception area should be provided by the user equipment corresponding to the private area.

[0338] If the perception area is a public area, then the perception privacy profile of the perception area should be configured according to laws and regulations, or obtained through the management device of the above public area.

[0339] The perceptual privacy profile of the perceptual area includes at least one of the following:

[0340] The first indication information is used to indicate whether sensing is allowed;

[0341] Validity period, such as a valid time interval represented by a start time and an end time, the validity period combined with the first indication information can indicate whether perception is allowed or not allowed within the validity period;

[0342] Service type: The service type and the first indication information may be combined to indicate whether perception of a certain service type is allowed or not allowed;

[0343] Notify UEs in the sensing area and allow sensing;

[0344] Perception requires notification and verification of end users within the perceived area. Perception is allowed only if the user agrees or if no response is received.

[0345] Perception requires notification and verification of end users within the perceived area. Perception is allowed only when all users authorize it.

[0346] Perception requires notification and verification of end users within the perceived area. Perception is allowed only when a predetermined threshold (e.g., 50% or 1) of users authorizes the user.

[0347] Notify the users of the detected area and allow detection;

[0348] Perception requires notification and verification of the users in the perceived area. Perception is allowed only if the users agree or if no response is received.

[0349] Perception requires notification and verification of the users in the perceived area. Perception is only allowed if the user authorizes it.

[0350] The user belonging to the perception area is, for a private area, the owner or manager of the perception area; if it is a public area, there may be no user belonging to the area, or the user belonging to the public area is the management department of the perception public area.

[0351] The second node should subscribe to changes in the perception privacy profile of the perception area. If the perception profile of the perception area sends a change, the second node can obtain the updated perception privacy profile of the perception area. The second node performs authorization based on the perception privacy profile of the perception area. Potential situations include at least one of the following:

[0352] For public safety awareness services, users should not refuse them, so they are allowed by default and authorized.

[0353] For auxiliary communication type perception services, one method is to allow by default, one method is to allow by notification (that is, the network should send a notification to the users in the perception area), and one method is to determine whether to allow based on the UE perception privacy profile in the perception area (such as the UE perception privacy profile indicates that auxiliary communication type perception services are not allowed).

[0354] For at least one of motion monitoring, imaging detection, indoor target tracking, outdoor target tracking, indoor target detection and tracking, outdoor target detection and tracking, sleep monitoring, motion monitoring, fall detection, gesture recognition, lip reading recognition, gait recognition, expression recognition, facial recognition, point cloud, imaging classification or imaging segmentation, one method is to not allow by default, one method is to allow by notification (that is, the network should send a notification to the user within the perception area), one method is to allow by verification (that is, the network should send verification to the user within the perception area, allow if permission is received, or allow if permission is received / no response), and one method is to determine whether to allow according to the UE perception privacy profile within the perception area (such as the perception privacy profile indicating that the perception service type is not allowed).

[0355] Step 3: If sensing is not permitted, authorization is rejected. The network (second node or other node) sends a sensing response, rejecting the sensing request. If authorization is granted, the network selects sensing-related function nodes (e.g., AMF, NEF, SF), sensing methods, and sensing nodes (base station and / or UE).

[0356] Step 4: The selected node receives the sensing configuration information (see the description of the above embodiment) and executes the sensing process.

[0357] In step 5, the network (the second node or another node) optionally sends a perception response to the perception result receiving node indicated by the perception request. When the first node is a UE, and the UE is both the perception measurement node and the perception result receiving node, one method is: in step 4, the UE reports the perception measurement data to the network, and the network then sends the generated perception result to the UE in this step. Another method is: the UE generates a perception result based on the perception measurement data without reporting the perception test data to the network, and the perception measurement reporting in step 4 and step 5 are skipped.

[0358] The embodiment of the present application supports both perception authorization associated with users within the perception area and authorization unrelated to the perception users, thereby meeting the needs of different service types.

[0359] In an embodiment of the present application, a second node receives a first message sent by a first node, the first message being used for a perception request; the second node obtains a target perception privacy profile corresponding to the first message; and the second node determines whether to allow the perception request based on the target perception privacy profile. A targeted perception privacy profile is obtained based on the first message, and then a specific determination is made as to whether to allow the perception request, thereby completing the authorization process for the perception service. This authorization process can improve the privacy protection performance of the perception service in the communication and perception fusion process.
