Wearable devices may also be called wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0090] In an embodiment of the present application, the network device may be a device for communicating with a mobile device. The network device may be an access point (AP) in WLAN, a base station (BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA, an evolved base station (eNB or eNodeB) in LTE, or a relay station or access point, or a vehicle-mounted device, a wearable device, and a network device (gNB) in an NR network, or a network device in a future evolved PLMN network or a network device in an NTN network, etc.

[0091] As an example and not a limitation, in an embodiment of the present application, the network device may have a mobile feature, for example, the network device may be a mobile device. Alternatively, the network device may be a satellite or a balloon station. For example, the satellite may be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. Optionally, the network device may also be a base station set up in a location such as land or water.

[0092] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources used by the cell (for example, frequency domain resources, or spectrum resources). The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0093] FIG1 exemplarily illustrates a communication system 100. The communication system includes a network device 110 and two terminal devices 120. In one embodiment, the communication system 100 may include multiple network devices 110, and each network device 110 may include a different number of terminal devices 120 within its coverage area, which is not limited in this embodiment of the present application.

[0094] In one embodiment, the communication system 100 may further include other network entities such as a Mobility Management Entity (MME) and an Access and Mobility Management Function (AMF), which is not limited in this embodiment of the present application.

[0095] Among them, the network equipment may include access network equipment and core network equipment. That is, the wireless communication system also includes multiple core networks for communicating with the access network equipment. The access network equipment can be an evolutionary base station (evolutional node B, abbreviated as eNB or e-NodeB) macro base station, micro base station (also called "small base station"), pico base station, access point (AP), transmission point (TP) or new generation Node B (gNodeB), etc. in a long-term evolution (LTE) system, a next-generation (mobile communication system) (next radio, NR) system or an authorized auxiliary access long-term evolution (LAA-LTE) system.

[0096] It should be understood that in the embodiments of the present application, a device having a communication function in a network / system may be referred to as a communication device. Taking the communication system shown in Figure 1 as an example, the communication device may include a network device and a terminal device having a communication function. The network device and the terminal device may be specific devices in the embodiments of the present application and will not be described in detail here. The communication device may also include other devices in the communication system, such as a network controller, a mobility management entity, and other network entities, which are not limited in the embodiments of the present application.

[0097] Figure 2 shows an exemplary diagram of the 5G network system architecture. Among them, the UE connects to the AN at the access layer through the Uu port, exchanges access layer messages and wireless data transmission, and the UE connects to the AMF at the non-access layer (NAS) through the N1 port, and exchanges NAS messages. AMF is the mobility management function in the core network, and SMF is the session management function in the core network. In addition to managing the mobility of the UE, AMF is also responsible for forwarding session management-related messages between the UE and SMF. PCF is the policy management function in the core network, which is responsible for formulating policies related to UE mobility management, session management, billing, etc. UPF is the user plane function in the core network, which transmits data with the external data network through the N6 interface and transmits data with the AN through the N3 interface.

[0098] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

[0099] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association. For example, "A indicates B" can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association between A and B.

[0100] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between the two, or an association relationship between the two, or a relationship between indication and being indicated, configuration and being configured, etc.

[0101] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0102] The radio electromagnetic wave signals used by cellular networks can be used not only for wireless data transmission and communication but also for environmental perception, such as user motion or gesture recognition, respiratory monitoring, terminal movement speed measurement, environmental imaging, and weather monitoring. Therefore, cellular networks can be considered not only for communication and data transmission, but also for acquiring sensory information.

[0103] For example, perception capabilities can be supported in B5G networks, and perception functions can be supported in the 3rd Generation Partnership Project (3GPP) network by adding a perception control network element (Sensing Function) and corresponding processes. When the application sends a perception request for the target UE to the core network of the 3GPP network, the core network selects the correct access network device or auxiliary UE through the perception control network element or AMF, and triggers the ability to perform perception-related wireless measurements, starts the measurement of perception information and generates perception results.

[0104] The main wireless perception scenarios of perception and communication integration (referred to as synaesthesia integration) are as follows:

[0105] 1) Base station echo sensing link (single gNB sensing): The base station sends a sensing signal and receives an echo signal.

[0106] 2) Inter-base station sensing link (gNB-gNB sensing): Base station B receives the sensing signal sent by base station A;

[0107] 3) Air interface uplink perception link (UE-gNB uplink perception): The base station receives the perception signal sent by the terminal;

[0108] 4) Air interface downlink perception link (UE-gNB downlink perception): The terminal receives the perception signal sent by the base station;

[0109] 5) Terminal echo perception link (single UE perception): The terminal sends a perception signal and receives an echo signal;

[0110] 6) Inter-terminal perception link (UE-UE perception): Terminal B receives the perception signal sent by terminal A.

[0111] Figure 3 is a schematic diagram of the perception process triggered by an application function (AF). In this process, the AF sends the perception request to the access and mobility management function (AMF) through the network exposure function (NEF), and then the AMF sends it to the perception function network element (SF), thereby realizing the function of SF controlling the base station or UE to perform perception measurement according to the perception request, and calculating based on the perception measurement data reported by the base station or UE and opening the perception results to the AF.

[0112] Among them, NEF performs authorization check on AF's service perception request. The authorization information can be stored locally in NEF or Unified Data Management (UDM). NEF can request authorization verification from UDM. NEF obtains privacy check information from UDM and performs privacy check. For example, if the UE does not allow a certain type of service to obtain perception measurement data or perception results related to itself, the NEF rejects the perception request. NEF routes the perception request according to the parameters of the perception request. From the perspective of the UE user, the perception measurement data or perception results include environmental information around the UE, which is a relatively private type of data. Drawing on the positioning privacy check idea in the Location Service (LCS), that is, if an application wants to obtain perception measurement data or perception results around the UE, the network needs to first confirm whether the user of the UE allows the application to obtain the above data.

[0113] Perception targets can be divided into UE targets and non-UE targets. In the existing scheme, authorization and authentication of perception tasks are only performed for target UEs. The authorization and authentication issues for objects whose perception targets are not UEs, or non-perception target objects within the perception range have not been discussed. Figure 4 is a schematic diagram of a perception scenario. As shown in Figure 4, when the perception target is a vehicle, how to obtain authorization from the vehicle owner; or when, in the process of perceiving object A, the perception data of the nearby perception object B is obtained, how to obtain authorization from the owner of object B; or when performing area-oriented perception, how to avoid collecting perception data of objects owned by unauthorized users (such as the stone in Figure 4). These issues are rarely addressed in current technical discussions.

[0114] As shown in Figure 4, when the perception target is a non-UE object or a non-target object is also within the perception range, since the object is not a 3GPP UE, it cannot establish a connection with the perception node (e.g., the Radio Access Network (RAN) in Figure 4). The non-UE object is unknown to the perception node. However, the object is definitely affected by the perception signal during the perception process, which poses a significant privacy risk. As shown in Figure 4, when the perception node perceives the target UE, the perception data of cars between the perception node RAN and the target UE, as well as people or objects near the target UE, are also collected into the perception data. For example, when the RAN node performs millimeter wave imaging, in addition to the target UE, image information of non-target objects such as cars and stones will also appear in the 3D image modeling of the perception results, thereby leaking the privacy of these objects without their knowledge. In addition, when a third-party application requests to perceive the car in Figure 4, if the car is not a 3GPP UE, the perception control network element cannot establish a connection with it through the perception node to obtain the car's authorization. In this case, the car's perception data may be leaked to the third-party application without the owner's knowledge.

[0115] The present application provides a method for perceptual authorization. FIG5 is a schematic flow chart of a perceptual authorization method 500 according to an embodiment of the present application. The method can be applied to any of the systems shown in FIG1-4, but is not limited thereto. The method includes at least part of the following contents.

[0116] S510: The first device sends first authorization information of a first item to the first network element. The first authorization information of the first item includes at least one of the following:

[0117] characteristic information of the first item;

[0118] First request information;

[0119] Contract information for the first item;

[0120] Identification information and / or a first indication of the first item.

[0121] In some embodiments, the characteristic information of the first object includes at least one of the shape, size, material, temperature, speed, orientation, position information allowed to be perceived, time information allowed to be perceived, position information prohibited to be perceived, and time information prohibited to be perceived.

[0122] In some embodiments, the first request information may be used to request the first network element to determine the perception measurement data of the first item. The perception measurement data of the first item obtained and stored by the first network element may be used by the perception network element, after performing a subsequent perception task, to compare the perception result with the perception measurement data of the first item, and ultimately filter out the perception measurement data that does not include the perception measurement data of the first item (e.g., an item prohibited from being perceived).

[0123] In some embodiments, the contract information of the first item may include identification information of the first item and / or a second indication, where the second indication is used to indicate whether the first item is allowed to be sensed or prohibited to be sensed. The contract information of the first item may be stored in a network element such as a UDM or a UMR.

[0124] In some implementations, the first indication may be used to indicate whether the first item is allowed to be sensed or prohibited to be sensed. The identification information and indication information of the first item may be registered in a network element such as a SF or a NEF.

[0125] The identification information of the first item may include a device identification, such as a UE ID, an IoT ID, a Tag ID, or a PINE ID.

[0126] The first network element may receive and save the first authorization information of each first item (such as the label information of the first item; or, the identification information of the first item and the corresponding indication information), including the first authorization information of the first item that is allowed to be perceived and the first item that is prohibited from being perceived. Alternatively, the first network element may receive and save the first authorization information of the first item that is prohibited from being perceived (such as the label information of the first item; or, the identification information of the first item and the corresponding indication information), and the contract information or indication information of the first item indicates that it is prohibited from being perceived; for the first item for which the relevant contract information or indication information is not saved, the first network element assumes that the first item is allowed to be perceived. Alternatively, the first network element may receive and save the first authorization information of the first item that is allowed to be perceived (such as the label information of the first item; or, the identification information of the first item and the corresponding indication information), and the contract information or indication information of the first item indicates that it is allowed to be perceived; for the first item for which the relevant contract information or indication information is not saved, the first network element assumes that the first item is prohibited from being perceived.

[0127] The identification information of the first item may include a device identification, for example, a UE ID, an Internet of Things (IoT) device ID, a tag ID, or a personal Internet of Things (PINE) device ID.

[0128] In some implementations, the first device may include a UE or an application function (AF).

[0129] In some implementations, the first network element may include a core network element, such as a SF, UDM, or UDR. The first network element may store first authorization information of the first item and / or, based on the first authorization information of the first item, obtain and store sensing measurement data of the first item. The first network element may perform authorization management on whether the first item is allowed to be sensed based on the stored information.

[0130] The perception authorization method proposed in the embodiment of this application includes three categories of methods: verification authorization before perception, data screening after perception, and detection of prohibition information during perception. Specifically:

[0131] 1. Before executing a perception task, the perception network element first queries the "blacklist" of items that are prohibited from being detected, and determines whether to execute the received perception task request by comparing their feature information.

[0132] 2. After collecting the perception measurement data, the perception network element deletes the data of the prohibited items from the perception results. For example, the network element uses the Network Data Analytics Function (NWDAF) to delete the perception measurement data of the items based on the item feature information. Alternatively, the user can request the perception network element to collect the perception measurement data of the items that are prohibited from being perceived in advance. After performing subsequent perception tasks, the perception network element can compare the perception results with the above-mentioned pre-collected perception measurement data, and finally filter out the perception measurement data that does not contain the perception measurement data of the prohibited items. Furthermore, the perception network element can also use the remaining perception measurement data after screening to generate perception results.

[0133] 3. The sensing network element detects termination information during the sensing task:

[0134] (1) Users can add a tag that prohibits perception on all objects (the tag can be regarded as an IoT device or UE) and register the tag identification information in the core network element. After receiving the perception signal, the tag will feed back its identification information to the relevant network node. The perception node will stop the perception task after identifying the identification information.

[0135] (2) Users can attach a tag with basic communication functions to their devices, and the device can provide feedback on whether the user is willing to be sensed after receiving the sensing signal.

[0136] The following is a detailed description of specific embodiments with reference to the accompanying drawings.

[0137] Example 1:

[0138] In this embodiment, the user registers the first authorization information of all properties that the user does not want to be perceived in the core network element. When the core network element receives a perception request, it can compare the characteristic information of all properties that are prohibited from being perceived in the user's contract message to determine whether to authorize the perception request.

[0139] Figure 6 is a flowchart of item-related information registration in an embodiment of the present application. As shown in Figure 6, a user can register the first authorization information of the perception of the item to which he belongs to the first network element through AF or UE. The first network element can be a core network element such as SF or UDM or UDR. The first authorization information may include contract information. The contract message is used to indicate that the item is allowed to be perceived or prohibited from being perceived. The contract message can be stored in a core network element such as UDM or UDR. Alternatively, the first network element (such as SF) can perceive the item indicated by the user and save the perception measurement data of the item based on the first request information that the user can send through AF or UE. The perception measurement data of the item can be stored in a core network element such as SF, UDR, UDM, etc. As shown in Figure 6, the specific process includes the following steps:

[0140] S610: The UE / AF registers first authorization information of prohibiting the perceived item (e.g., the first item) to the first network element. The first authorization information of the first item may include at least one of the following:

[0141] a. Feature information of the first object, such as the object's shape, size, material, temperature, speed, direction, etc., as well as information such as the object's permitted and prohibited sensing locations, permitted and prohibited sensing times, etc.

[0142] b. A first request message, requesting the SF to pre-scan and obtain sensory measurement data of the first item and store the sensory measurement data of the first item in the SF or another core network element. After completing the sensing task, the SF may compare the obtained sensory measurement data with pre-stored sensory measurement data of items prohibited from being sensed, thereby deleting the pre-stored prohibited data from the obtained sensory measurement data.

[0143] c. Contract information of the first item. This contract information may include identification information of the first item and / or a second indication, where the second indication may be used to indicate whether the first item is permitted or prohibited from being sensed. The identification information of the first item may include a device identifier, such as a UE ID, IoT ID, Tag ID, or PINE ID. The contract information of the first item may be stored in a network element, such as a UDM or UMR.

[0144] d. Identification information of the first item and a first indication. The first indication may be used to indicate whether the first item is permitted or prohibited from being sensed. The identification information of the first item may include a device identifier, such as a UE ID, IoT ID, Tag ID, or PINE ID. The identification information and indication information of the first item may be registered in a network element, such as a SF or NEF.

[0145] S620: The first network element feeds back to the UE / AF that the first authorization information of the item prohibited from being sensed has been successfully registered.

[0146] The above example describes registering the first authorization information for an item that the user prohibits from being sensed. In other embodiments of the present application, the user may also register the first authorization information for a sensed item that is permitted to be sensed through the UE / AF; or, the user may register the first authorization information for both permitted and prohibited sensed items through the UE / AF. In each of the above cases, the content of the first authorization information is consistent with that described in step S610 and will not be repeated here.

[0147] After the first network element receives and saves the first authorization information of each first object, the perception network element can apply for authorization from the first network element before performing the perception task. The process of applying for authorization is not much different from the existing process. Only the information of the queried authorization object is different from the existing process. For example, NEF performs an authorization check on the perception request of AF. The first authorization information can be stored locally in UDM, and NEF can request authorization verification from UDM. NEF obtains the contract information or indication information of the first object (the first object can be the perception target of the perception request, or the object within the perception range of the perception request) from UDM and performs an authorization check. For example, if the UE does not allow a certain type of service to obtain perception measurement data or perception results related to the first object, the NEF rejects the perception request.

[0148] This embodiment of the present application also provides a perception authorization method, which can be applied to a first network element, such as a core network element such as a SF, UDM, or UDR. Figure 7 is a schematic flow chart of a perception authorization method 700 according to an embodiment of the present application. This method can be applied to any of the systems shown in Figures 1-4, but is not limited thereto. The method includes at least part of the following content.

[0149] S710: A first network element receives first authorization information of a first item, where the first authorization information of the first item includes at least one of the following:

[0150] characteristic information of the first item;

[0151] First request information;

[0152] Contract information for the first item;

[0153] identification information and / or a first indication of the first item.

[0154] In some embodiments, the characteristic information of the first object includes at least one of the shape, size, material, temperature, speed, orientation, position information allowed to be perceived, time information allowed to be perceived, position information prohibited to be perceived, and time information prohibited to be perceived.

[0155] In some embodiments, the first request information is used to request the first network element to determine the perception measurement data of the first item. The first network element pre-perceives perception based on the first request information, obtains and stores the perception measurement data of the first item (e.g., the item prohibited from perception). This perception measurement data can be used by the perception network element to delete the perception measurement data of the item prohibited from perception from the collected perception measurement data after the perception network element completes the collection of the perception measurement data. The perception network element can further use the remaining perception measurement data to generate a perception result.

[0156] In some embodiments, the contract information of the first item includes identification information of the first item and / or a second indication, where the second indication is used to indicate whether the first item is allowed to be sensed or prohibited to be sensed.

[0157] In some embodiments, the first indication is used to indicate whether the first object is allowed to be sensed or prohibited to be sensed.

[0158] In some embodiments, the identification information of the first item includes a device identification, such as a UE ID, an IoT device ID, a tag ID, or a PINE ID.

[0159] Further, in some embodiments, if the first network element is not a perception network element (such as SF), after the perception network element (such as SF) performs the perception task according to the perception task request, the first network element may send the characteristic information and / or perception measurement data of the first object that matches the perception task description information in the perception task request to the perception network element (such as SF), so that the perception network element (such as SF) can delete the part overlapping with the perception measurement data of the first object from the perception measurement data obtained after performing the perception task, and send the remaining perception measurement data after deletion to the perception task initiator (consumer); or use the remaining perception measurement data after deletion to generate a perception result, and send the perception result to the perception task initiator (consumer). Alternatively, if the first network element is a perception network element (such as SF), after the first network element receives a perception request containing perception task description information and performs the perception task according to the perception task request, it can search for the pre-saved characteristic information and / or perception measurement data of the first object that matches the perception task description information, and delete the part overlapping with the perception measurement data of the first object from the perception measurement data obtained after performing the perception task, and send the remaining perception measurement data after deletion to the perception task initiator (consumer); or use the remaining perception measurement data after deletion to generate a perception result, and send the perception result to the perception task initiator (consumer).

[0160] The above-mentioned perception task description information may include at least one of perception target area information and perception time information.

[0161] The above example is used to delete the part that overlaps with the perception measurement data of the first object from the perception measurement data obtained after the perception network element completes the perception task. In other embodiments, the first network element may, after receiving the identification information of the perceived object (such as the first object) (the identification information may be sent by the perceived object or by a terminal device associated with the perceived object), search for the contract information or indication information of the first object based on the identification information of the first object, send the contract information or indication information of the first object to the perception network element (such as SF), and the perception network element (such as SF) determines whether the first object is allowed to be perceived based on the contract information or indication information of the first object, and terminates the perception task if the first object is not allowed to be perceived; or, the first network element searches for the contract information or indication information of the first object based on the identification information of the first object, and sends a perception prohibition indication or a perception permission indication to the perception network element (such as SF) based on the contract information or indication information. The perception network element may terminate the perception task if it receives the perception prohibition indication.

[0162] Specifically, the first network element receives identification information of the first item from the perception network element; and the first network element sends second authorization information of the first item to the perception network element.

[0163] In some implementations, the first network element sending the second authorization information of the first item to the sensing network element includes:

[0164] The identification information of the first item searches for the contract information or the first indication of the first item, and sends the second authorization information of the first item to the perception network element according to the contract information or the first indication of the first item. The second authorization information of the first item includes the perception prohibition indication or the perception permission indication of the first item.

[0165] Alternatively, the first network element sends the second authorization information of the first item to the sensing network element, including:

[0166] The first network element searches for the tag contract information or the first indication of the first item according to the identification information of the first item, and sends the second authorization information of the first item to the perception network element. The second authorization information of the first item includes the contract information or the first indication of the first item.

[0167] The following is a detailed description of specific embodiments with reference to the accompanying drawings.

[0168] Example 2:

[0169] In this embodiment, after the perception network element (such as SF) collects the target perception measurement data, the perception measurement data of the prohibited perception objects is deleted from the perception measurement data. Figure 8 is an implementation flow chart of deleting the data of prohibited perception items after obtaining the perception measurement data according to an embodiment of the present application. As shown in Figure 8, when the user has stored the perception measurement data of the prohibited perception items in the first network element, after the SF collects the perception measurement data, it can obtain the perception measurement data of the prohibited perception items from the first network element or locally, and delete the data of the prohibited perception items from the collected perception measurement data, and finally send the filtered data to the perception task initiator (consumer); or use the remaining perception measurement data after screening to generate a perception result, and send the perception result to the perception task initiator. The consumer can be AF, UE or other core network elements. The specific process is as follows:

[0170] S810: The consumer sends a sensing request to the SF, where the sensing request includes sensing task description information, such as sensing task type, sensing requirements, sensing method, etc. For example, the sensing requirements may include at least one of sensing target area information and sensing time information.

[0171] S820: SF performs the sensing task according to the sensing request.

[0172] S830: The SF obtains sensing measurement data of the prohibited object from the local network (when the first network element is the SF) or the first network element (when the first network element is not the SF). For example, the SF may find matching sensing measurement data of the prohibited object based on sensing task description information, such as sensing target area information, sensing time information, and other service requirements.

[0173] S840: SF deletes the portion of the perception measurement data obtained after performing the perception task in step S820 that overlaps with the perception measurement data of the prohibited objects obtained in step S830, thereby filtering the perception measurement data obtained after performing the perception task.

[0174] S850: The SF sends the filtered perception measurement data to the consumer; alternatively, the SF calculates a perception result using the filtered perception measurement data and sends the perception result to the consumer.

[0175] In this way, the perception measurement data or perception results sent by SF to the consumer do not contain information about prohibited items, thereby providing a certain degree of privacy protection.

[0176] Example 3:

[0177] In this embodiment, after the perception network element (such as SF) collects the target perception measurement data, it uses other network elements (such as NWDAF) to delete the perception measurement data of the prohibited objects from the perception measurement data. Figure 9 is another implementation flow chart of deleting the data of prohibited objects after obtaining the perception measurement data according to an embodiment of the present application. As shown in Figure 9, when the first network element stores not the perception measurement data of the prohibited objects but their feature information, SF can use NWDAF to delete the data of the prohibited objects from the data collected by the perception task. The specific process is as follows:

[0178] S910: The consumer sends a sensing request to the SF, where the sensing request includes sensing task description information, such as sensing task type, sensing requirements, sensing method, etc. For example, the sensing requirements may include at least one of sensing target area information and sensing time information.

[0179] S920: SF performs the sensing task according to the sensing request.

[0180] S930: SF requests the first network element (when the first network element is not the SF) to obtain relevant data (such as feature information) of the prohibited items. The request information may include perception task description information, such as perception target area, perception time and other perception service requirements.

[0181] S940: The first network element may return feature information of prohibited objects within the sensing target area and within the sensing time to the SF.

[0182] The above S930 and S940 are applicable when the first network element is not SF. When the first network element is not SF, SF can search the pre-stored first authorization information for feature information of prohibited objects within the sensing target area and within the sensing time.

[0183] S950: SF sends the perception measurement data obtained after performing the perception task and the feature information of the prohibited objects to the NWDAF.

[0184] S960: NWDAF uses artificial intelligence (AI) technology to identify the perception measurement data corresponding to the characteristic information of prohibited objects (that is, the data of prohibited objects) from the perception measurement data collected by the perception task, and deletes this data, thereby filtering the perception measurement data collected by the perception task and sending the filtered perception measurement data back to SF.

[0185] S970: The SF sends the filtered perception measurement data to the consumer; alternatively, the SF calculates a perception result using the filtered perception measurement data and sends the perception result to the consumer.

[0186] In this way, the perception measurement data or perception results sent by SF to the consumer do not contain information about prohibited items, thereby providing a certain degree of privacy protection.

[0187] Example 4:

[0188] In this embodiment, the user can add a label prohibiting perception to the property (the label can be regarded as an IoT device or UE), and register the identification information of the property in the core network element. After receiving the perception signal, the label feeds back the identification information of the property to the RAN, and transmits it to the perception network element through the RAN. Alternatively, if the property is a terminal device (such as an IoT device or UE, etc.), the property can send its identification information to the RAN, and transmit it to the perception network element through the RAN. The RAN in the embodiment of the present application may refer to an access network device, which may be a RAN, access point (AP), gNB (gNodeB), eNB (eNodeB) and other access network devices or sites. The RAN in subsequent embodiments is the same as that referred to here and will not be repeated later. The perception network element can use the identification information of the property to initiate an authorization check request to the first network element, and terminate the ongoing perception task if the authorization check fails.

[0189] Figure 10A is a flowchart of an implementation of determining whether to terminate a sensing task based on object identification information according to an embodiment of the present application. As shown in Figure 10A, the tag on the sensed object is prohibited from being activated when receiving the energy of the sensing signal. The tag will send its Tag ID (which can also be regarded as the identification information of the sensed object) to the SF via the RAN. The SF can query the first network element for this identification information and terminate the sensing task based on the query result. The specific process is as follows:

[0190] S1010: After receiving the sensing signal, the tag on the object sends the tag ID to the RAN.

[0191] S1020: The RAN forwards the Tag ID, the task identifier (Task ID) of the currently executed sensing task, and sensing task description information to the SF. The sensing task description information may include at least one of sensing target area information and sensing time information.

[0192] S1030: The SF sends a perception authorization query request to the first network element, where the perception authorization query request includes a Tag ID.

[0193] S1040: The first network element searches for the pre-saved first authorization information according to the Tag ID, and obtains the contract information of the item indicated by the Tag ID. If the contract information indicates that perception is prohibited, the first network element sends a perception prohibition indication to the SF.

[0194] S1050: SF terminates the sensing task according to the received sensing prohibition instruction, and informs the consumer of the sensing failure instruction and the reason for the failure.

[0195] Figure 10B is a flowchart of an implementation of determining whether to terminate a sensing task based on object identification information according to an embodiment of the present application. As shown in Figure 10B, the tag on the sensed object is prohibited from being activated when receiving the energy of the sensing signal. The tag will send its Tag ID (which can also be regarded as the identification information of the sensed object) to the UE participating in the sensing task, and the UE participating in the sensing task will then send the Tag ID to the SF via the RAN. The SF can query the first network element for the identification information and terminate the sensing task based on the query result. The specific process is as follows:

[0196] S1011: After receiving the sensing signal, the tag on the object sends the Tag ID to the UE participating in the sensing task.

[0197] S1012: The UE participating in the sensing task forwards the Tag ID, the task identifier (Task ID) of the sensing task currently being executed, and sensing task description information to the RAN. The sensing task description information may include at least one of sensing target area information and sensing time information.

[0198] S1013: The RAN forwards the Tag ID, the task identifier (Task ID) of the currently executed sensing task, and sensing task description information to the SF. The sensing task description information may include at least one of sensing target area information and sensing time information.

[0199] S1014: The SF sends a perception authorization query request to the first network element, where the perception authorization query request includes a Tag ID.

[0200] S1015: The first network element searches for the pre-saved first authorization information according to the Tag ID, and obtains the contract information of the item indicated by the Tag ID. If the contract information indicates that perception is prohibited, the first network element sends a prohibition perception indication to the SF.

[0201] S1016: SF terminates the sensing task according to the received sensing prohibition instruction, and informs the consumer of the sensing failure instruction and the reason for the failure.

[0202] In the above example, the identification information is transmitted by a tag on the sensed object. If the sensed object is a terminal device (such as an IoT device or UE), the sensed object can also transmit its identification information.

[0203] In this way, during the perception process, objects that are prohibited from being perceived can trigger the termination of the perception process after receiving the perception signal, providing a certain degree of privacy protection.

[0204] Embodiment 5:

[0205] In this embodiment, the user can add a label that prohibits perception to the property (the label can be regarded as an IoT device or UE), and register the identification information of the property in the core network element. After receiving the perception signal, the label feeds back the identification information of the property to the RAN, and transmits it to the perception network element through the RAN. Alternatively, if the property is a terminal device (such as an IoT device or UE, etc.), the property can send its identification information to the RAN, and transmit it to the perception network element through the RAN. The perception network element can use the identification information of the property to initiate an authorization check request to the first network element, determine whether the property is allowed to be perceived based on the contract information of the property fed back by the first network element, and terminate the ongoing perception task if it is determined that it is not allowed to be perceived. The difference from Example 4 is that in this embodiment, the perception network element determines whether the item is allowed to be perceived based on the tag information of the item, while in Example 4, the first network element determines whether the item is allowed to be perceived.

[0206] Figure 11A is a flowchart of another implementation of determining whether to terminate a sensing task based on object identification information according to an embodiment of the present application. As shown in Figure 11A, the tag on the sensed object is prohibited from being activated when receiving the energy of the sensing signal. The tag will send its Tag ID (which can also be regarded as the identification information of the sensed object) to the SF via the RAN. The SF can query the first network element for the contract information corresponding to the identification information and determine whether to terminate the sensing task based on the contract information. The specific process is as follows:

[0207] S1110: After receiving the sensing signal, the tag on the object sends the tag ID to the RAN.

[0208] S1120: The RAN forwards the Tag ID, the task identifier (Task ID) of the currently executed sensing task, and sensing task description information to the SF. The sensing task description information may include at least one of sensing target area information and sensing time information.

[0209] S1130: The SF sends a perception authorization query request to the first network element, where the perception authorization query request includes a Tag ID.

[0210] S1140: The first network element searches for the pre-stored first authorization information according to the Tag ID, obtains the contract information of the item indicated by the Tag ID, and returns the contract information to the SF. The contract information is used to indicate whether the item indicated by the Tag ID is prohibited from being sensed or allowed to be sensed.

[0211] S1150: SF determines whether the item indicated by the Tag ID is prohibited from being sensed based on the contract information. If it is prohibited from being sensed, the sensing task is terminated and the sensing failure indication and the reason for the failure are notified to the consumer.

[0212] Figure 11B is another implementation flowchart of determining whether to terminate the sensing task based on the object identification information according to an embodiment of the present application. As shown in Figure 11B, the tag on the sensed object is prohibited from being activated when receiving the energy of the sensing signal. The tag will send its Tag ID (which can also be regarded as the identification information of the sensed object) to the UE participating in the sensing task, and the UE participating in the sensing task will then send the Tag ID to the SF via the RAN. The SF can query the first network element for the contract information corresponding to the identification information, and determine whether to terminate the sensing task based on the contract information. The specific process is as follows:

[0213] S1111: After receiving the sensing signal, the tag on the object sends the Tag ID to the UE participating in the sensing task.

[0214] S1112: The UE participating in the sensing task forwards the Tag ID and the task identifier (Task ID) of the currently executed sensing task, and sensing task description information to the RAN. The sensing task description information may include at least one of sensing target area information and sensing time information.

[0215] S1113: The RAN forwards the Tag ID, the task ID of the currently executed sensing task, and sensing task description information to the SF. The sensing task description information may include at least one of sensing target area information and sensing time information.

[0216] S1114: The SF sends a perception authorization query request to the first network element, where the perception authorization query request includes a Tag ID.

[0217] S1115: The first network element searches for the pre-stored first authorization information according to the Tag ID, obtains the contract information of the item indicated by the Tag ID, and returns the contract information to the SF. The contract information is used to indicate whether the item indicated by the Tag ID is prohibited from being sensed or allowed to be sensed.

[0218] S1116: SF determines whether the item indicated by the Tag ID is prohibited from being sensed based on the contract information. If it is prohibited from being sensed, the sensing task is terminated and the sensing failure indication and failure reason are notified to the consumer.

[0219] In the above example, the identification information is transmitted by a tag on the sensed object. If the sensed object is a terminal device (such as an IoT device or UE), the sensed object can also transmit its identification information.

[0220] In this way, during the perception process, objects that are prohibited from being perceived can trigger the termination of the perception process after receiving the perception signal, providing a certain degree of privacy protection.

[0221] Example 6:

[0222] In this embodiment, the user's belongings can be terminal devices (such as UE or IoT devices), or the user can add a tag to the belongings (the tag can be considered as a terminal device associated with the belongings, such as UE or IoT devices). During the sensing process, after receiving the sensing signal, the object or tag can send a message to inform the RAN whether it agrees to be sensed, or inform the RAN of its identification information. For example, after receiving the sensing signal, the terminal device or tag sends a sensing prohibition instruction and / or the identification information of the terminal device.

[0223] Figure 12 is a flowchart of a Tag notifying the SF that sensing is prohibited according to an embodiment of the present application. As shown in Figure 12, the tag device on the prohibited sensing object is activated when it receives the energy of the sensing signal. The tag device notifies the SF through the RAN that it is prohibited from being sensed, thereby terminating the sensing task. The specific process is as follows:

[0224] S1210: After receiving the sensing signal, the tag on the item sends a sensing prohibition instruction to the RAN.

[0225] S1220: RAN forwards the sensing prohibition instruction and the task identifier (Task ID) of the currently executed sensing task and the sensing task description information to SF.

[0226] S1230: SF terminates the sensing task and informs the consumer of the sensing failure indication and the reason for the failure.

[0227] FIG12 is an example of a tag on an object sending a sensing prohibition instruction. In this embodiment, the sensing prohibition instruction can also be sent by the object.

[0228] In this way, during the perception process, the object or tag on the object that is prohibited from being perceived can trigger the termination of the perception process after receiving the perception signal, providing a certain degree of privacy protection.

[0229] Embodiment seven:

[0230] In this embodiment, the user's belongings can be terminal devices (such as UE or IoT devices), or the user can add a tag to the belongings (the tag can be considered as a terminal device associated with the belongings, such as UE or IoT devices). During the sensing process, after receiving the sensing signal, the object or tag can send a message to inform the RAN whether it agrees to be sensed, or inform the RAN of its identification information. For example, after receiving the sensing signal, the object or tag sends a sensing prohibition indication and / or the identification information of the terminal device. This message can be forwarded to the RAN via the UE participating in the sensing task.

[0231] Figure 13 is a flowchart of another implementation of a Tag notifying the SF that sensing is prohibited according to an embodiment of the present application. As shown in Figure 13, the tag device on the prohibited sensing object is activated and sends a signal when it receives the energy of the sensing signal. The signal is received by the UE participating in the sensing task and forwarded to the SF via the RAN, thereby terminating the sensing task. The specific process is as follows:

[0232] S1310: After receiving the sensing signal, the tag on the item sends a sensing prohibition indication to the UE.

[0233] S1320: The UE sends the sensing prohibition indication, the task identifier (Task ID) of the currently executed sensing task, and the sensing task description information to the RAN.

[0234] S1330: RAN forwards the sensing prohibition instruction and the Task ID and sensing task description information of the currently executed sensing task to SF.

[0235] S1340: SF terminates the sensing task and informs the consumer of the sensing failure indication and the reason for the failure.

[0236] FIG13 is an example of a tag on an object sending a sensing prohibition instruction. In this embodiment, the sensing prohibition instruction can also be sent by the object.

[0237] In this way, during the perception process, the object or tag on the object that is prohibited from being perceived can trigger the termination of the perception process after receiving the perception signal, providing a certain degree of privacy protection.

[0238] The present application also provides a perception authorization method. FIG14 is a schematic flow chart of a perception authorization method 1400 according to an embodiment of the present application. The method can be applied to any of the systems shown in FIG1-4, but is not limited thereto. The method includes at least part of the following content.

[0239] S1410: The perception network element obtains second authorization information of the first item, where the second authorization information of the first item includes at least one of the following:

[0240] characteristic information of the first item;

[0241] perceptual measurement data of the first item;

[0242] The first item's perception prohibition indication;

[0243] Contract information for the first item;

[0244] A first indication of a first item.

[0245] The perception network element may include a SF.

[0246] In some embodiments, the characteristic information of the first object includes at least one of the shape, size, material, temperature, speed, orientation, position information allowed to be perceived, time information allowed to be perceived, position information prohibited to be perceived, and time information prohibited to be perceived.

[0247] In some embodiments, the contract information of the first item includes identification information of the first item and / or a second indication, where the second indication is used to indicate whether the first item is allowed to be perceived or prohibited to be perceived.

[0248] In some embodiments, the first indication is used to indicate whether the first item is allowed to be sensed or prohibited to be sensed.

[0249] In some implementations, the sensing network element obtains the second authorization information of the first item, including:

[0250] The sensing network element sends identification information of the first item to the first network element;

[0251] The sensing network element receives second authorization information of the first item from the first network element.

[0252] In some implementations, the method further includes the sensing network element receiving identification information of the first item sent by the first item or a terminal device associated with the first item.

[0253] In some embodiments, the identification information of the first item includes a device identification.

[0254] In some implementations, the device identifier includes a UE ID, an IoT ID, a Tag ID, or a PINE ID.

[0255] The identification information of the first object may include a device identification. For example, the perception network element may receive the second authorization information of the first object during the execution of the perception task, and use the received second authorization information of the first object to determine whether to terminate the perception task being executed. For example, the perception network element terminates the perception task of the first object based on the second authorization information of the first object. For example, during the perception process, the perception network element receives a perception prohibition indication or identification information sent by the first object (the first object may be a terminal device, such as a UE or an IoT device) or a tag on the first object (the tag may be a terminal device, such as a UE or an IoT device). If a perception prohibition indication is received, the perception network element may terminate the ongoing perception task; if the identification information of the first object is received, the identification information of the first object may be used to request the first network element to perform an authorization check. If the authorization check fails, the perception network element may terminate the ongoing perception task.

[0256] In some embodiments, the perception network element may receive second authorization information of the first object, and after the perception task is completed, based on the second authorization information of the first object, delete the perception measurement data of the first object from the perception measurement data obtained after performing the perception task. For example, the perception network element receives a perception request containing perception task description information, obtains the perception measurement data of the first object that matches the perception task description information; and deletes the perception measurement data of the first object from the perception measurement data obtained after performing the perception task. Specifically, the perception network element may search locally for the perception measurement data of the first object that matches the perception task description information; or, the perception network element may obtain the perception measurement data of the first object that matches the perception task description information from the first network element. The perception task description information may include at least one of perception target area information and perception time information.

[0257] In other embodiments, the perception network element may receive the second authorization information of the first object (such as the characteristic information of the first object), and after the perception task is completed, request other network elements to delete the perception measurement data of the first object from the perception measurement data obtained after performing the perception task based on the second authorization information of the first object (such as the characteristic information of the first object). For example, the perception network element sends the perception measurement data obtained after performing the perception task and the characteristic information of the first object to the second network element; the perception network element receives first data from the second network element, and the first data includes the remaining data after deleting the perception measurement data of the first object from the perception measurement data obtained after performing the perception task. Wherein, the way in which the perception network element obtains the characteristic information of the first object can be: the perception network element sends a request to the first network element, and the request includes perception task description information; the perception network element receives the characteristic information of the first object that matches the perception task description information from the first network element.

[0258] The above-mentioned second network element may include NWDAF, which can use AI technology to identify the perception measurement data corresponding to the characteristic information of the first object (that is, the data of the first object) from the perception measurement data obtained after performing the perception task, and delete the perception measurement data from the perception measurement data obtained after performing the perception task, and return the remaining perception measurement data to SF.

[0259] In other embodiments, the perception network element may terminate the perception task for the first item based on at least one of the perception prohibition indication, contract information, and first indication of the first item. For example, the perception network element sends identification information of the first item to the first network element, and receives at least one of the perception prohibition indication, contract information, and first indication of the first item from the first network element. Prior to this, the perception network element may receive identification information of the first item sent by the first item or a terminal device associated with the first item. The identification information of the first item may include a device identifier, such as a UE ID, an IoT ID, a tag ID, or a PINE ID. The perception network element may also receive a perception prohibition indication sent by the first item or a terminal device associated with the first item.

[0260] In the above-mentioned various methods, if the sensing network element ends the sensing task, it may send a sensing failure indication, for example, sending a sensing failure indication to the initiator (consumer) of the sensing task, and the sensing failure indication may include the failure reason.

[0266] The above embodiments are not independent of each other, but can be combined with each other. The implementation methods in different embodiments can be reasonably combined and will not be listed one by one here.

[0267] The method proposed in the embodiment of the present application can solve the perception authorization problem when the perception target is a non-3GPP UE object, as well as the perception authorization problem of non-perception target objects within the perception range by verifying authorization before perception, filtering data after perception, and detecting prohibited information during perception, thereby providing users with a certain degree of privacy protection.
