Description

Communication method and device Technical Field

[0001] The present application relates to the field of communications, and more specifically, to a communication method, device, computer-readable storage medium, computer program product, and computer program. Background Art

[0002] In related technologies, communication networks such as cellular networks are only used for communication. However, the radio electromagnetic wave signals used by cellular networks can not only be used for wireless data transmission and communication purposes, but also have environmental perception capabilities, such as user action or gesture recognition, breathing monitoring, terminal movement speed measurement, environmental imaging, weather monitoring, etc. Therefore, in the future, cellular networks can be considered not only for communication and data transmission, but also for the acquisition of perception information. However, in a communication scenario where communication and perception are integrated, it is possible that when a certain perception task perceives the target object or area, other electronic devices are affected, and these electronic devices affected by the perception task may have privacy leakage problems. Therefore, in this scenario, how to identify the electronic devices affected by the perception task and then protect the privacy security of the electronic devices affected by the perception task becomes a problem that needs to be solved.

That is, the wireless communication system also includes multiple core networks for communicating with the access network device. The access network equipment may be an evolutionary base station (evolutional node B, which may be referred to as eNB or e-NodeB) macro base station, micro base station (also called "small base station"), micro base station, access point (AP), transmission point (TP) or new generation Node B (gNodeB) 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. It should be understood that the equipment with communication functions in the network / system in the embodiment of the present application may be referred to as communication equipment. Taking the communication system shown in Figure 1 as an example, the communication equipment may include network equipment and terminal equipment with communication functions. The network equipment and terminal equipment may be specific equipment in the embodiment of the present application, which will not be repeated here; the communication equipment may also include other equipment in the communication system, such as network controllers, mobile management entities and other network entities, which are not limited in the embodiment of the present application.

[0055] To facilitate understanding of the embodiments of the present application, the following briefly describes the basic processes and basic concepts involved in the embodiments of the present application. It should be understood that the basic processes and basic concepts introduced below do not limit the embodiments of the present application.

[0056] The 5G network system architecture is shown in Figure 2, which includes: NSSF (Network Slice Selection Function) is mainly used to manage network slice related information, such as selecting network slices for terminal devices; AUSF (Authentication Server Function) is used to complete the identity authentication function of user access; UDM (Unified Data Management) is used to manage and store contract data and authentication data; AMF (Access and Mobility Management Function) is used to complete mobility management, security anchor and security context management, etc. In addition to managing the mobility of UE, AMF is also responsible for forwarding session management related messages between UE and SMF; SMF (Session Management Function) is used to complete session management, UE IP address allocation and management, etc.; PCF (Policy Control Function) is responsible for formulating policies related to UE mobility management, session management, billing, etc.; AF (Application Function) is used for external application servers; UPF (User Plane Function) is used for external application servers. Function) is used for complex user plane processing, such as forwarding traffic between the wireless access network and the Internet, reporting traffic usage, and implementing QoS (Quality of Service) policies. DN (Data Network) refers to the 5GC external data network (such as the Internet).

[0057] In addition, data is transmitted between various nodes in the 5G Core Network (5G Core Network), between user equipment (UE) and 5G Core Network nodes, between the UE and the Radio Access Network (RAN), and between the RAN and 5G Core Network nodes through corresponding interfaces. For example, as shown in Figure 2, data is transmitted between the AMF and the NSSF in the 5G Core Network (5G Core Network) via interface N22; data is transmitted between the AMF and the SMF via interface N11; data is transmitted between the AMF and the AUSF via interface N12; and data is transmitted between the AMF and the UDM via interface N8. Data is transmitted between the SMF and the UPF via interface N4. The UPF transmits data to the external data network via interface N6 and to the AN via interface N3. The UE connects to the AN via the Uu interface for access layer communication, exchanging access layer messages and wireless data transmission. The UE connects to the AMF via the N1 interface for non-access layer (NAS) communication, exchanging NAS messages. Data is transmitted between the RAN and the AMF via interface N2, and between the RAN and the UPF via interface N3. It should be understood that the above only describes the interfaces between some nodes, and other interfaces between other 5GC nodes in Figure 2 are not described one by one.

[0058] Cellular networks, including 5G networks, are used only for communication. However, the radio electromagnetic wave signals used by cellular networks can not only be used for wireless data transmission and communication purposes, but also have environmental perception capabilities, such as user action or gesture recognition, breathing monitoring, terminal movement speed measurement, environmental imaging, weather monitoring, etc. Therefore, in the future, cellular networks can be considered not only for communication and data transmission, but also for the acquisition of perception information. Currently, discussions are underway to support perception capabilities in B5G networks. By adding sensing function network elements and corresponding processes, perception functions can be supported in 3GPP networks. For example, when an application sends a perception request for a 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, that is, realizes interawareness integration in the network. The main wireless sensing scenarios for this integrated intersensory sensing are as follows: 1) Base station echo sensing link (single gNB sensing): The base station sends a sensing signal and receives an echo signal; 2) Inter-base station sensing link (gNB-gNB sensing): Base station B receives a sensing signal sent by base station A; 3) Air interface uplink sensing link (UE-gNB uplink sensing): The base station receives a sensing signal sent by the terminal; 4) Air interface downlink sensing link (UE-gNB downlink sensing): The terminal receives a sensing signal sent by the base station; 5) Terminal echo sensing link (single UE sensing): The terminal sends a sensing signal and receives an echo signal; 6) Inter-terminal sensing link (UE-UE sensing): Terminal B receives a sensing signal sent by terminal A. In the initial stages of B5G communication sensing integration, consideration will be given to reusing existing air interface signals as much as possible for sensing, avoiding excessive air interface enhancements. Furthermore, given the complexity of full-duplex implementation, collaborative sensing between terminals and / or base stations is a priority.

[0059] As shown in Figure 3, it is a flowchart of a possible control of access network equipment or UE to perform UE-level perception operations, including: steps 301 to 303, AF sends a perception request to AMF through NEF (Network Exposure Function), and the perception request may include the perception service type, service requirements, etc.; wherein, in step 302, NEF performs perception authorization on the service perception request of AF, and the perception authorization may be locally stored in NEF or UDM, and NEF may request authorization verification from UDM. NEF obtains privacy check information from UDM and performs privacy check. For example, if UE (or target UE) does not allow a certain type of service to obtain perception measurement data or perception results related to itself, NEF rejects the perception request. If UE allows a certain type of service to obtain perception measurement data or perception results related to itself, NEF routes the perception request to AMF according to the parameters of the perception request. In step 304, the AMF selects an SF based on the sensing request. In step 305, the AMF sends the sensing request to the SF network element, which may include the SF-C (Control Plane) and the SF-U (User Plane), as shown in Figure 3. In step 306, the SF controls the base station or UE to perform sensing measurements based on the sensing request. Step 306 may include one of the following: step 306a, the NG-RAN (with the AMF and SF) performs a RAN-based sensing sub-procedure; step 306b, the UE performs a UE-assisted sensing sub-procedure via the NG-RAN (with the AMF and SF); or step 306c, multiple UEs (NG-RAN, AMF, and SF) perform a UE-based sensing sub-procedure. In step 307, the SF performs sensing calculations based on the sensing measurement data reported by the base station or UE. In steps 308 and 309, the SF sends a sensing response to the UDM and / or NEF via the AMF. The sensing response carries sensing target information, and the NEF and / or UDM ultimately makes the sensing response available to the AF.

[0060] From the UE user's perspective, perception measurement data or results include information about the UE's surrounding environment, which is relatively private. Drawing on the location privacy check concept in LCS (Location Service), if an application wishes to obtain perception measurement data or results around the UE, the network must first confirm whether the UE user has authorized the application to obtain such data. Therefore, in the above solution, authorization for perception measurement data is performed in step 302.

[0061] In the above scheme, authorization and authentication for the sensing task are performed only for the target UE (i.e., the UE affected by the sensing task). Detailed research has not been conducted on the privacy protection of non-target UEs. However, whether for target-oriented or area-oriented sensing, ensuring the privacy of non-target UEs within the sensing range is a crucial issue for future sensing tasks, especially high-precision sensing tasks. The primary issue in obtaining sensing authorization for non-target UEs is how the network identifies potentially affected non-target UEs. Related technologies have not yet addressed the issue of identifying non-target UEs within the current sensing task range. Furthermore, related technologies only address authorization of certain types of sensing services through UE subscription messages. However, a UE's tolerance for sensing tasks can vary dynamically. For example, a user's permission for the same sensing task may vary depending on the location (indoors or outdoors) or time of day (daytime or late at night). Therefore, direct confirmation with the user provides the most accurate authorization information. Furthermore, the subscription message does not clearly define the authorization granularity for sensing tasks, only addressing authorization at the sensing service type level. However, users may have varying tolerance for the same sensing task at different precisions and resolutions. For example, a user might only allow low-resolution perception. Furthermore, users may have varying levels of trust in the initiators of different perception tasks. For example, a user might only allow family or friends to perform certain types of perception tasks. Therefore, more fine-grained perception authorization is needed to protect user privacy.

[0062] It should be understood that the terms "system" and "network" are often used interchangeably in this article. The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the objects associated before and after are in an "or" relationship. 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 relationship. For example, A indicates B, which 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 relationship between A and B. In the description of the embodiments of this application, the term "corresponding" can mean that there is a direct or indirect correspondence between the two, or it can mean that there is an association relationship between the two, or it can mean a relationship between indication and indication, configuration and configuration, etc.

[0072] In this embodiment, the above-mentioned first message carries a perception request, which may refer to the first message being a perception request, or may refer to the first message carrying a perception request and other content.

[0076] For example, the perception request in the second message can carry relevant information of each of the one or more electronic devices in the target perception area, that is, the second message can also be called a perception request sent by the first network device to the second network device. In addition to carrying the content of the original perception request, the perception request can also carry relevant information of each of the one or more electronic devices in the target perception area, that is, the perception request sent by the first network device to the second network device includes two information elements, namely the content of the original perception request and the relevant information of each of the one or more electronic devices in the target perception area. For another example, the second message can carry the perception request and the relevant information of each of the one or more electronic devices in the target perception area respectively, that is, the perception request and the relevant information of each of the one or more electronic devices in the target perception area can be carried as two different information elements in the second message. That is, in the process of forwarding the perception request initiated by the first device (carried by the first message) from the first network device to the second network device, the first network device obtains the relevant information of each of the one or more electronic devices in the target perception area; then the first network device sends the relevant information of each electronic device in the target perception area along with the perception request (that is, the relevant information of each electronic device in the target perception area and the perception request are carried in the second message) to the second network device.

[0077] Before the first network device sends the second message, the method may further include: the first network device determining one or more electronic devices within the target perception area based on relevant information of the first perception task.

[0078] In one possible example, the first perception task is an object-oriented perception task. The relevant information of the first perception task includes relevant information of the target perception object of the first perception task; the electronic device is different from the target perception object. In this case, the one or more electronic devices within the aforementioned target perception area may refer to one or more electronic devices within the target perception area that are different from the target perception object; optionally, the one or more electronic devices within the target perception area that are different from the target perception object may refer to one or more electronic devices located within the target perception area, different from the target perception object, and affected by the first perception task.

[0079] Optionally, the first network device determines one or more electronic devices within the target perception area based on relevant information of the first perception task, including: the first network device determines the second position of the target perception object based on relevant information of the target perception object; the first network device determines the target perception area at each of one or more granularities corresponding to the target perception object based on the second position of the target perception object; the first network device determines one or more electronic devices different from the target perception object from one or more candidate devices within the target perception area at each granularity.

[0080] The relevant information of the target perception object includes at least one of the following: identification information of the target perception object and the first position of the target perception object.

[0081] Exemplarily, the relevant information of the target perception object includes identification information of the target perception object.

[0082] The target sensing object may be a Target terminal, and the target terminal may be a target UE. The identification information may be a network identification and / or ID, and the description of the ID and the network identification is the same as that in the above embodiment and will not be repeated.

[0083] The first network device determines the second position of the target perception object based on the relevant information of the target perception object, which can be: the first network device determines the second position of the target perception object based on the UE context (Context) of all UEs stored locally and the identification information of the target perception object. Exemplarily, the second position can be at least one of a cell, a sector, a TA, or geographical coordinates represented by longitude and latitude, which are not exhaustively listed here.

[0084] The one or more granularities include at least one of the following: a registration area (RA), a tracking area (TA), a cell, a sector, and a specified radius. A sector refers to the geographical area covered by an access network device's antenna; an access network device can cover one or more sectors. A cell refers to a logical concept within a sector; one sector corresponds to one or more cells.

[0085] The first network device determines the target perception area at each of one or more granularities corresponding to the target perception object based on the second position of the target perception object, which may include: the first network device determines at least one of the following corresponding to the target perception object based on the second position of the target perception object: the target perception area under RA, the target perception area under TA, the target perception area under the cell, the target perception area under the sector, and the target perception area under a specified radius. The target perception area under the RA may be a target perception area with RA as the granularity (or dimension), that is, the target perception area is specifically a target RA; the target perception area under the TA may refer to a target perception area with TA as the granularity (or dimension), that is, the target perception area may be a target TA; the target perception area under the cell may be a target perception area with cell as the granularity (or dimension), that is, the target perception area is specifically a target cell; the target perception area under the sector may be a target perception area with sector as the granularity (or dimension), that is, the target perception area is specifically a target sector; the target perception area under the specified radius may be a target perception area with the specified radius as the granularity (or dimension), that is, the target perception area is specifically a target perception area within a specified radius centered on the target perception object.

[0086] The first network device determines one or more electronic devices different from the target perception object from one or more candidate devices within the target perception area at each granularity, which may include: the first network device determines one or more candidate devices located in the target perception area at each granularity based on the location information of each electronic device among all electronic devices; and then the first network device determines one or more electronic devices different from the target perception object from the one or more candidate devices within the target perception area at each granularity. Any electronic device different from the target perception object may refer to any electronic device with different identification information from the target perception object. The location information of each electronic device may refer to at least one of the identifier of the registration area of ​​the electronic device, the TAI (Tracking Area Identity) where the electronic device was last (or last) registered, and the ID of the cell where the electronic device is located, wherein the TAI (Tracking Area Identity) where the electronic device was last (or last) registered can be expressed as TAI of last Registration. In some possible examples, any electronic device different from the target perception object may be referred to as a non-target UE or other UE.

[0087] Among them, the second message carries the relevant information of each electronic device in one or more electronic devices within the target perception area at each granularity. In the second message, the relevant information of each electronic device within the target perception area at each granularity can be expressed in the form of a list. Exemplarily, the relevant information of each electronic device within the target perception area at each granularity can be a list consisting of the IDs of each electronic device that is different from the target perception object and is affected by the first perception task within the target perception area at each granularity (or simply referred to as a non-target ID list affected by the first perception task at each granularity). In the following, if there is no special explanation, the affected UE ID list may include an Affected non-target UE ID list, and no repetition is made; and the Affected non-target UE ID list has the same meaning as the list consisting of the IDs of each electronic device that is different from the target perception object and is affected by the first perception task within the target perception area, and no repetition is made. In some possible examples, the above-mentioned non-target UE may also be referred to as a non-perceiving target UE.

[0088] Exemplarily, the relevant information of the target perception object includes the first position of the target perception object.

[0089] The target perception object may refer to a target perception object. Exemplarily, the target perception object may be referred to as a target object, or as a non-UE target, or as a non-UE target object, or as a non-UE target object. For example, the target perception object may include but is not limited to at least one of the following: a vehicle, a vehicle identification (such as a license plate), etc. It should be understood that this is only an exemplary description and is not intended to limit all possible types of target perception objects. Alternatively, the aforementioned target perception object may also be a target terminal, all within the scope of protection of this embodiment. The first position may be any one of the following: a geographic location, a cell location, a registration area location, a tracking area location, and the like. The geographic location may be a location coordinate, such as a longitude and latitude.

[0090] The first network device determines the second position of the target perception object based on the relevant information of the target perception object. This may be: the first network device uses the first position of the target perception object as the second position of the target perception object.

[0091] The one or more granularities include at least one of the following: a registration area RA, a tracking area TA, a cell, a sector, and a specified radius. The first network device determines the target perception area at each granularity of the one or more granularities corresponding to the target perception object based on the second position of the target perception object, and the first network device determines the processing of one or more electronic devices different from the target perception object from one or more candidate devices within the target perception area at each granularity, which is the same as the above embodiment and will not be repeated. Any electronic device different from the target perception object may refer to any UE that is different from the first position of the target perception object. In some possible examples, any electronic device different from the target perception object may be referred to as a non-target UE or other UE.

[0092] The second message carries relevant information about each electronic device in the target perception area of ​​each granularity, that is, a list of the IDs of each electronic device that is different from the target perception object and is affected by the first perception task within the target perception area of ​​each granularity (or simply referred to as a list of non-target IDs affected by the first perception task at each granularity). The detailed description of the second message is the same as the above example and is not repeated here.

[0093] Optionally, the first network device determines one or more electronic devices within the target perception area based on relevant information of the first perception task, including: the first network device determines the second position of the target perception object based on relevant information of the target perception object; the first network device determines the target perception area at the target granularity corresponding to the target perception object based on the second position of the target perception object and the target granularity; the first network device determines one or more electronic devices different from the target perception object from one or more candidate devices within the target perception area at the target granularity corresponding to the target perception object.

[0094] The target granularity can be used to indicate the range (or range size) that the first perception task needs to perceive. In some possible examples, the target granularity can also be called the perception range. The target granularity may include one of the following: RA (Registration Area), TA (Tracking Area), cell, sector, or specified radius. Among them, the specified radius can be indicated according to the actual situation, such as a few meters, or hundreds of meters, or larger or smaller; for example, if the specified radius is a few meters, it means that the range that the first perception task needs to perceive is within a few meters around the target perception object. If the specified radius is several hundred meters, it means that the range that the first perception task needs to perceive is within a few hundred meters around the target perception object.

[0095] The target granularity is preconfigured; or, the target granularity is carried by relevant information of the first perception task.

[0096] For example, the target granularity is preconfigured, which may mean that the target granularity is preconfigured by the operator, or may mean that the target granularity may be configured for the first network device by another network device. For example, the target granularity may be configured for the first network device by the AF, or by the SMF, or by a second network device with perception capabilities, etc. The manner in which the first network device obtains the target granularity is not limited here.

[0097] For another example, the target granularity is carried by the relevant information of the first perception task. That is, the target granularity can be determined by the first device, and the target granularity is included in the relevant information of the first perception task included in the perception request. The first device is the initiating device of the first perception task, or can be called the initiator of the first perception task. For example, for a target-oriented first perception task, the initiator of the first perception task, that is, the first device (such as UE, or AF, etc.), will include the target UE ID (that is, the target perception object is the target UE) and the perception range (that is, the aforementioned target granularity) in the perception request; or include the target position coordinates (corresponding to the aforementioned non-UE target) and the perception range in the perception request.

[0098] The relevant information of the target perception object includes the identification information of the target perception object and / or the first position of the target perception object. The relevant descriptions of the identification information of the target perception object and the first position of the target perception object are the same as those in the previous embodiment and are not repeated here.

[0099] The process of determining the second position of the target perception object by the first network device based on the relevant information of the target perception object is the same as that in the above embodiment and will not be repeated here. The target perception area under the target granularity corresponding to the target perception object may include one of the following: a target perception area (or target RA) under RA, a target perception area (or target TA) under TA, a target perception area (or target cell) under a cell, a target perception area (or target sector) under a sector, and a target perception area under a specified radius. The first network device determines one or more electronic devices different from the target perception object from one or more candidate devices within the target perception area under the target granularity corresponding to the target perception object, which may include: the first network device determines one or more candidate devices within the target perception area under the target granularity, and then the first network device determines one or more electronic devices different from the target perception object from the one or more candidate devices within the target perception area under the target granularity. Any electronic device different from the target perception object may refer to any UE with different identification information from the target perception object, and / or any electronic device different from the first position of the target perception object. In some possible examples, any electronic device different from the target perception object may be referred to as a non-target UE or other UE.

[0100] The second message carries relevant information of each electronic device in the one or more electronic devices within the target perception area at the target granularity. In the second message, the relevant information of each electronic device in the one or more electronic devices within the target perception area at the target granularity can be expressed in the form of a list. For example, the relevant information of each electronic device in the target perception area at the target granularity can be a list consisting of the IDs of each electronic device different from the target perception object within the target perception area at the target granularity that is affected by the first perception task, or simply a list of non-target IDs affected by the first perception task at the target granularity.

[0101] In one possible example, the first perception task is an area-oriented perception task. The relevant information of the first perception task includes a target perception area for the first perception task. In this case, the one or more electronic devices within the aforementioned target perception area may refer to all electronic devices within the target perception area, that is, all electronic devices affected by the first perception task.

[0102] The target perception area of ​​the above-mentioned first perception task may include one or more areas of interest (AoI, Area Of Interest) corresponding to the first perception task. Among them, any AoI may be composed of at least one of the following: one or more target tracking areas (TA, Tracking Area), one or more target cells, one or more target sectors, one or more target perception areas of a specified radius. Optionally, in the perception request, the target perception area of ​​the above-mentioned first perception task may be indicated by at least one of the following: one or more TA identifiers, one or more target cell identifiers, one or more target sector identifiers, and the location of one or more target perception areas of a specified radius.

[0103] The first network device determines one or more electronic devices within the target perception area based on the relevant information of the first perception task, including: the first network device determines one or more candidate devices located within the target perception area, and uses the one or more candidate devices as the one or more electronic devices. Exemplarily, the first network device determines one or more candidate devices located within the target perception area, and uses the one or more candidate devices as the one or more electronic devices, which can be: the first network device can identify all candidate electronic devices located within the target perception area from the UE context of all electronic devices stored in itself, and use all candidate electronic devices as electronic devices located within the target perception area. That is, by executing the processing provided by this embodiment, the first network device can eventually obtain all electronic devices located within the target perception area, and all electronic devices located within the target perception area can refer to all electronic devices affected by the first perception task. For example, all electronic devices within the target perception area can be represented as all non-target electronic devices (or non-target UEs) affected by the first perception task within the target perception area, or simply as non-target UEs affected by the first perception task.

[0104] In this example, the aforementioned second message may carry relevant information of each electronic device in one or more electronic devices within the target perception area. The relevant information of each electronic device within the target perception area may be a list consisting of the IDs of the electronic devices affected by the first perception task within the target perception area, for example, it may be expressed as an Affected UE ID list. The detailed description of the second message is the same as that of the aforementioned embodiment and will not be repeated here.

[0105] Furthermore, privacy protection for one or more electronic devices within the target sensing area (e.g., including the aforementioned non-target UEs) can be divided into the following three approaches: Authorization via subscription message: The network determines whether a sensing service is permitted by querying the subscription message of the non-target UE. User confirmation: The network directly confirms with the non-target UE and determines whether the sensing service is permitted based on the UE's confirmation result. Secondary authorization after data collection: In cases where the network has already collected sensing measurement data (e.g., the network has performed a similar task and has stored relevant data), the network can confirm with the user whether the data can be made available to a specific UE, RAN, network element, or AF. Regardless of which authorization approach is adopted, the network must address the issue of how to determine the non-target UEs that will be affected by the sensing task. This is because the sensing task information only carries target information, such as the target UE ID and target area identifier, and it is not possible to know in advance all UEs that may be affected by the sensing task (e.g., non-target UEs). Therefore, the 5GS needs to infer the potentially affected non-target UEs in advance based on the relevant information of the sensing task. In other words, it needs to infer the one or more electronic devices located within the target sensing area in advance based on the relevant information of the sensing task. Specifically, the method for determining one or more electronic devices within the above-mentioned target perception area is summarized as follows: find its serving AMF through the target UE ID, and then query other non-target UEs recorded on the AMF that are in the same area as the target UE, such as the same TA or Cell; find other non-target UEs being served by the RAN node that performs the perception task.

[0106] In conjunction with Figure 6, taking the first device as the first UE or the first device as the AF, the first network device as the AMF, and the second network device as the SF as an example, the processing scheme provided by the above embodiment is exemplified. In Figure 6, the first message is exemplified as a perception request, and the second message is also exemplified as a perception request. The scenario illustrated in Figure 6 is: when the perception request is forwarded by the AMF, that is, when the AMF selects the SF, the AMF identifies the UE within the perception range based on the locally stored UE context. When the perception request initiated by the first UE or AF is forwarded by the AMF to the SF, the AMF can assist in identifying the UE that may be affected by the first perception task, and send the identified UE ID list along with the perception request to the SF. The processing flow is as follows:

[0107] Step 601a: The first UE sends a sensing request to the AMF; or, Step 601b: The AF sends a sensing request to the AMF. The sensing request may carry at least one of the following: the target UE ID, the Area of ​​Interest (AoI), and the sensing range. The target UE ID is the identifier of the target sensing object in the aforementioned embodiment; the AoI is the target sensing area of ​​the first sensing task in the aforementioned embodiment; and the sensing range is the target granularity in the aforementioned embodiment.

[0108] In step 601a, the first UE may send a perception request to the AMF through the RAN (Radio Access Network). In step 601b, the AF may send a perception request to the AMF through the NEF. The above-mentioned UE or AF may be referred to as a task initiator (or a perception task initiator, or a first perception task initiator). It should be understood that the task initiator may be other network elements in addition to the UE or AF illustrated in FIG6 , and this example does not list them all. Specifically for the above-mentioned steps 601a and 601b: for target-oriented perception tasks, the task initiator (UE, AF or other network element) will include the ID of the target UE, or the target location coordinates (corresponding to the non-UE target, i.e., the first location of the target perception object in the aforementioned embodiment) and the perception range in the perception request. The perception range is used to indicate the range that the perception task needs to perceive, which may be RA granularity, TA granularity, cell granularity or a custom perception range. For example, the custom perception range may be a specified radius, such as a few meters or hundreds of meters around the perception target. For area-oriented perception tasks, the perception request will include the target perception area of ​​the first perception task, which is the area of ​​interest AoI. For example, AoI can be one or more tracking areas (Tracking Area), and one TA can include one or more cells.

[0109] Step 602: The AMF forwards the sensing request to the SF. The sensing request carries a list of affected UE IDs and may also carry at least one of the target UE ID, sensing range, and AoI.

[0110] During the processing of step 602, the AMF can determine the relevant information of each electronic device in the target perception area, and then carry the Affected UE ID list in the perception request and send it to the SF. That is, after receiving the perception request, the AMF can compare the location information in the UE context of all UEs stored locally, thereby identifying the non-target UE whose location information overlaps with or is included in the location information of the target UE, and carry the ID list of the non-target UE in the perception request and send it to the SF. The above-mentioned location information includes Registration Area, TAI of last Registration, User Location Information (including the Cell ID where the UE is located), etc. Specifically, according to the differences in the relevant information of the first perception task contained in the perception request (hereinafter referred to as the information contained in the perception request), the following processing methods can be used:

[0111] a) The perception request includes the target UE ID (i.e., the identification information of the target perception object) and the perception scope (i.e., the target granularity): The AMF can identify the non-target UEs in the area level indicated by the perception scope of the target UE based on the UE context of all UEs stored locally, and use the non-target UEs in the area level indicated by the perception scope of the target UE as the UE ID list affected by the first perception task. For example, if the perception scope is TA, the non-target UEs in the same TA as the target UE can be identified as the UEs affected by the first perception task based on the UE context, and the UE ID list affected by the first perception task is included in the perception request and sent to the SF.

[0112] b) The perception request only contains the target UE ID: The AMF can identify non-target UEs in different granularity (or different dimensions) such as RA, TA, cell, etc. where the target UE is located based on the UE context of all UEs stored locally. And send the non-target UE ID list in the same RA as the target UE, the non-target UE ID list in the same TA as the target UE, and the non-target UE ID list in the same Cell as the target UE to the SF. It can also select one of the UE ID lists under the above different granularity and send it to the SF based on the pre-configured information or perception task requirements.

[0113] c) The perception request only contains the perception area AoI (i.e., the target perception area of ​​the first perception task): The AMF can identify other UEs in the area indicated by the AoI (i.e., all UEs in the area indicated by the AoI) based on the UE context of all UEs stored locally, and include the UE ID list affected by the first perception task in the perception request message and send it to the SF.

[0114] d) The perception request contains the location information of the non-UE target object (i.e., the first location of the target perception object), such as specific coordinates (the external coordinate information in the perception request can be converted into internal coordinate information understandable by 5GS by NEF): AMF identifies the non-target UE in the same RA, TA, cell and other different granularity (or different dimensions) as the non-UE target object, and sends the non-target UE ID list in the same RA as the non-UE target object, the non-target UE ID list in the same TA as the non-UE target object, and the non-target UE ID list in the same Cell as the non-UE target object to the SF. One of the above UE ID lists can also be selected and sent to the SF based on pre-configured information or perception task requirements.

[0115] e) The perception request includes the location and perception range of the non-UE target object: The AMF can identify the non-target UE within the area level indicated by the perception range of the non-UE target object based on the UE context of all UEs stored locally, and send the non-target UE list affected by the first perception task to the SF.

[0116] By adopting the above example, AMF can identify non-target UEs that may be affected by the first perception task for SF when forwarding the perception request. While forwarding the first perception task (i.e., the perception request), the UE ID list affected by the first perception task can be sent to SF, which saves signaling loss to a certain extent. By using the perception range specified by the initiator of the perception task, AMF can retrieve UE context within a smaller range, reducing retrieval time and computational load. The method of AMF assisting in identifying UEs can be completed before SF executes sub-processes such as perception node selection, so that SF can request authorization of non-target UEs before executing the perception sub-process, thereby improving processing efficiency.

[0117] In some possible implementations, the first network device receiving a first message includes: the first network device receiving the first message sent by a second network device, the first message being used to request information related to each electronic device within a target sensing area. The first network device sending a second message includes: the first network device sending the second message to the second network device. Correspondingly, the second network device receiving the second message includes: the second network device receiving the second message sent by the first network device.

[0118] In this embodiment, the first network device may be a first core network device or a second access network device; the second network device may be a second core network device with a perception function.

[0119] Before the second network device receives the second message, the method also includes: the second network device receives a perception request sent by the first device, the perception request carries relevant information of the first perception task, and the first device is the initiating device of the first perception task; the second network device determines the first network device based on the relevant information of the first perception task; the second network device sends the first message to the first network device, the first message is used to request to obtain relevant information of each electronic device in the target perception area, and the first message carries relevant information of the first perception task.

[0120] The first message in this embodiment is different from the aforementioned embodiment. In this embodiment, the first message is not a perception request or does not carry a perception request, but only carries relevant information of the first perception task. The first message is also only used to obtain relevant information of each electronic device in the target perception area, that is, the first message is only used to request the first network device to identify the UE located in the target perception area. Exemplarily, the first message in this embodiment can be referred to as a UE ID acquisition request. The UE located in the target perception area may be a non-target UE located in the target perception area, different from the target UE, and affected by the first perception task, or the UE located in the target perception area refers to the UE located in the target perception area and affected by the first perception task.

[0121] In this embodiment, the second message is also different from the aforementioned embodiment, and the second message only carries relevant information of each electronic device in the target sensing area. Exemplarily, the second message in this embodiment can be called a UE ID acquisition response. That is, the second message only carries a list of UE IDs within the target sensing area that are affected by the first sensing task. For example, the second message carries a list of non-target UE IDs that are located in the target sensing area, are different from the target UE, and are affected by the first sensing task, or the second message carries a list of UE IDs that are located in the target sensing area and are affected by the first sensing task.

[0122] The aforementioned second network device receiving the perception request sent by the first device may refer to the second network device directly receiving the perception request sent by the first device. In other words, the first device does not need to forward the perception request to the second network device via the first network device, but instead directly sends the perception request to the second network device that performs the specific perception function. The aforementioned first device may be one of the following: a first terminal device, a first access network device, a first server, or a third core network device. The relevant description of the first device is the same as that of the aforementioned embodiment and is not repeated here.

[0123] Optionally, the first network device may be a first core network device. In this case, the second network device determines the first network device based on the relevant information of the first sensing task, and the determination may vary depending on the relevant information of the first sensing task.

[0124] Exemplarily, the first perception task is an object-oriented perception task, and the relevant information of the first perception task includes relevant information of a target perception object; the second network device determines the first network device based on the relevant information of the first perception task, including: the second network device determines the second location of the target perception object based on the relevant information of the target perception object; and the second network device determines the first network device whose serving area covers the second location of the target perception object. The second location of the target perception object may include at least one of the following: the geographic location of the target perception object, the identifier of the cell where the target perception object is located, the TAI where the target perception object is located, the identifier of the registration area where the target perception object is located, and the identifier of a sector within the cell where the target perception object is located. The second network device determines the first network device whose serving area covers the second location of the target perception object, which may refer to: the second network device determines, based on the service area corresponding to each candidate core network device among one or more candidate core network devices, a candidate core network device within the serving area that contains the second location of the target perception object, and uses the candidate core network device within the serving area that contains the second location of the target perception object as the first network device. The aforementioned candidate core network device may be a candidate AMF, and the first network device may be an AMF.

[0125] It should be understood that, in this example, the relevant information of the first perception task may also include a target granularity. The description of the target granularity is the same as that in the aforementioned embodiment and will not be repeated here.

[0126] Exemplarily, the first perception task is a region-oriented perception task, and the relevant information of the first perception task includes the target perception area of ​​the first perception task; the second network device determines the first network device based on the relevant information of the first perception task, including: the second network device determines the first network device whose service area covers the target perception area. For example, the second network device determines the candidate core network device containing the target perception area in the service area based on the service area corresponding to each candidate core network device in one or more candidate core network devices, and uses the candidate core network device containing the target perception area in the service area as the first network device. The aforementioned candidate core network device can be a candidate AMF, and the first network device can be an AMF.

[0127] The processing after the aforementioned first network device receives the first message for requesting to obtain relevant information of each electronic device within the target perception area and before sending the second message may include: the first network device determines one or more electronic devices within the target perception area based on the relevant information of the first perception task.

[0128] In some possible implementations, the first network device is a first core network device.

[0129] Optionally, the relevant information of the first perception task includes relevant information of a target perception object of the first perception task.

[0130] The first network device determines one or more electronic devices within the target perception area based on the relevant information of the first perception task, including: the first network device uses its own service area as the target perception area; the first network device determines one or more electronic devices different from the target perception object from one or more candidate devices located in the target perception area. That is, when the first perception task is an object-oriented perception task and the relevant information of the first perception task only includes the relevant information of the target perception object of the first perception task, the first network device uses its own service area as the target perception area, and then uses all electronic devices within its own service area as all candidate electronic devices, and then determines one or more electronic devices different from the target perception object from all candidate electronic devices; the one or more electronic devices different from the target perception object can be called one or more non-target electronic devices (or non-target UEs) different from the target perception object.

[0131] In this case, the content carried by the second message can be a list consisting of the IDs of each electronic device in the target perception area that is affected by the first perception task and is different from the target perception object (or simply a list of non-target IDs affected by the first perception task). Alternatively, the first network device determines one or more electronic devices in the target perception area based on the relevant information of the first perception task, including: the first network device determines the second position of the target perception object based on the relevant information of the target perception object; the first network device determines the target perception area at each of one or more granularities corresponding to the target perception object based on the second position of the target perception object; the first network device determines one or more electronic devices different from the target perception object from one or more candidate devices in the target perception area at each granularity.

[0132] Among them, the first network device determines the target perception area at each of the one or more granularities corresponding to the target perception object based on the second position of the target perception object, which can be: the first network device determines the target perception area at one or more granularities containing the second position of the target perception object in its own service area based on the second position of the target perception object. The processing of the first network device determining the second position of the target perception object based on the relevant information of the target perception object is the same as the above embodiment and will not be repeated. The processing of the first network device determining one or more electronic devices different from the target perception object from one or more candidate devices within the target perception area at each granularity is the same as the above embodiment and will not be repeated. In this case, the content carried by the second message can be the relevant information of each electronic device in the one or more electronic devices within the target perception area at each granularity, that is, a list of IDs of each electronic device different from the target perception object that is affected by the first perception task within the target perception area at each granularity (or simply a list of non-target IDs affected by the first perception task at each granularity). The detailed description of the second message is the same as the above example and will not be repeated.

[0133] Alternatively, the first network device determines one or more electronic devices within the target perception area based on relevant information of the first perception task, including: the first network device determines the second position of the target perception object based on relevant information of the target perception object; the first network device determines the target perception area at the target granularity corresponding to the target perception object based on the second position of the target perception object and the target granularity; the first network device determines one or more electronic devices different from the target perception object from one or more candidate devices within the target perception area at the target granularity corresponding to the target perception object.

[0134] Among them, the target granularity is the perception range, and the target granularity can be pre-configured or can be carried by the relevant information of the first perception task. The detailed description of the target granularity is the same as that of the aforementioned embodiment and will not be repeated. And the first network device determines the second position of the target perception object based on the relevant information of the target perception object; the first network device determines the target perception area under the target granularity corresponding to the target perception object based on the second position of the target perception object and the target granularity; the first network device determines the specific processing of one or more electronic devices different from the target perception object from one or more candidate devices within the target perception area under the target granularity corresponding to the target perception object, which is also the same as the aforementioned embodiment and will not be repeated. In this case, the above-mentioned second message can carry the relevant information of each electronic device in the target perception area under the target granularity; the specific carrying method and detailed description of the relevant information of each electronic device in the target perception area under the target granularity are also the same as the aforementioned embodiment and will not be repeated.

[0135] Optionally, the relevant information of the first perception task includes a target perception area of ​​the first perception task.

[0136] In this case, the first network device determines one or more electronic devices within the target perception area based on the relevant information of the first perception task, including: the first network device determines one or more candidate devices located within the target perception area, and uses the one or more candidate devices as the one or more electronic devices. The above detailed description of the first network device determining one or more candidate devices located within the target perception area and using the one or more candidate devices as the one or more electronic devices is the same as the aforementioned embodiment and will not be repeated. In this case, the second message may carry relevant information of each electronic device in the one or more electronic devices within the target perception area. The detailed description of the relevant information of each electronic device within the target perception area is the same as the aforementioned embodiment and will not be repeated.

[0137] In conjunction with Figure 7, taking the first network device as AMF and the second network device as SF as an example, the processing scheme provided by the above embodiment is exemplified. The scenario illustrated in Figure 7 is: when the perception request sent by the first UE (i.e., the aforementioned first device) or AF is not forwarded to the SF via the AMF, but the first UE or AF directly sends the perception request to the SF, the SF selects the AMF based on the relevant information of the target perception object (such as the ID of the target UE or the first position of the target perception object) or the target perception area, and the AMF identifies the non-target UEs within the perception range or all UEs affected by the first perception task based on the locally stored UE context. As shown in Figure 7, when the perception request is sent directly to the SF node (not via the AMF), for target-oriented perception, the SF can find the AMF whose serving area covers the location of the target perception object; for area-oriented perception, the SF can find the AMF whose serving area covers the target perception area. Then, the SF requests the AMF to help it identify the non-target UEs within the perception area. The specific process is as follows:

[0138] Step 701: SF sends a UE ID acquisition request to AMF.

[0139] The above-mentioned UE ID acquisition request message may be the first message for requesting to obtain relevant information of each electronic device within the target perception area in the aforementioned embodiment. For target-oriented perception, the message may include the target (Target) UE ID as shown in Figure 7, or may include the first position of the target perception object (i.e., the location information of the target object); further, the message may also include information such as the perception range as shown in Figure 7. For area-oriented perception, the message may include the AoI shown in Figure 7, that is, the target perception area of ​​the first perception task.

[0140] In step 702, the AMF sends a UE ID acquisition response to the SF. The UE ID acquisition response is specifically the aforementioned second message carrying relevant information about each of the one or more electronic devices within the target sensing area. For example, as shown in Figure 7, the UE ID acquisition response may only carry the affected UE ID list (Affected UE ID list).

[0141] In this step, the method by which the AMF determines the affected UE ID list is the same as in the previous embodiment and is not described in detail. It should be noted that the second message in this example is only a UE ID acquisition response message carrying the affected UE ID list, and the second message no longer carries a perception request or is no longer used to request perception.

[0142] This example mainly solves the problem of obtaining the non-target UE ID in a scenario where the perception request is not forwarded to the SF via the AMF, or the SF needs to query the UE to which the existing perception measurement data belongs.

[0143] In some possible implementations, the first network device is a first access network device.

[0144] The second network device determines the first network device based on the relevant information of the first sensing task, including one of the following:

[0145] The second network device determines, when determining that the sensing mode of the first sensing task is a mode in which the access network device performs sensing, a candidate access network device for performing the first sensing task based on the relevant information of the first sensing task, and determines the first network device based on the candidate access network device for performing the first sensing task;

[0146] The second network device determines, upon determining that the sensing mode of the first sensing task is a mode in which the terminal device performs sensing, a candidate terminal device for performing the first sensing task based on relevant information of the first sensing task, and determines the first network device based on the candidate terminal device for performing the first sensing task;

[0147] When the second network device determines that the perception mode of the first perception task is a mode in which the access network device and the terminal device collaborate to perform perception, the second network device determines the candidate access network device for performing the first perception task and the candidate terminal device for performing the first perception task based on the relevant information of the first perception task, and determines the first network device based on the candidate access network device for performing the first perception task and the candidate terminal device for performing the first perception task.

[0148] Exemplarily, the perception request may also include information related to the perception mode of the first perception task. After the second network device receives the perception request sent by the first device, the second network device determines the perception mode of the first perception task, which may include: the second network device determines the perception mode of the first perception task based on the information related to the perception mode of the first perception task included in the perception request.

[0149] The perception mode-related information of the first perception task may include one of the following: a mode in which the access network device performs perception, a mode in which the terminal device performs perception, and a mode in which the access network device and the terminal device collaborate to perform perception.

[0150] The mode in which an access network device performs perception may include one of the following: a mode in which a single access network device performs perception, and a mode in which multiple access network devices perform perception collaboratively. The mode in which a single access network device performs perception may be a mode in which a single access network device sends a perception signal and receives an echo signal of the perception signal. The mode in which a single access network device performs perception may also be referred to as a self-transmitting and self-receiving perception mode of the access network device; the mode in which multiple access network devices perform perception collaboratively may be a mode in which one or more access network devices send a perception signal, and another one or more access network devices receive the perception signal and send an echo signal of the perception signal. It should be noted that in the mode in which the access network performs perception, each access network device that performs perception may be referred to as an access network device perception node.

[0151] The mode in which a terminal device performs perception may include one of the following: a mode in which a single terminal device performs perception, and a mode in which multiple terminal devices perform perception in collaboration. The mode in which a single terminal device performs perception may be a mode in which a single terminal device sends a perception signal and receives an echo signal of the perception signal. This mode in which a single terminal device performs perception may be referred to as a terminal device self-transmitting and self-receiving perception mode; the mode in which multiple terminal devices perform perception in collaboration may be a mode in which one or more terminal devices send a perception signal, and another one or more terminal devices receive the perception signal and send an echo signal of the perception signal. It should be noted that in the mode in which terminal devices perform perception, each terminal device performing perception may be referred to as a terminal device perception node.

[0152] The mode in which access network devices collaborate with terminal devices to perform perception may include one of the following: one or more terminal devices sending a perception signal, one or more access network devices receiving the perception signal and transmitting an echo signal of the perception signal; or one or more access network devices sending a perception signal, one or more terminal devices receiving the perception signal and transmitting an echo signal of the perception signal. It should be noted that in the mode in which access network devices collaborate with terminal devices to perform perception, each terminal device performing perception may be referred to as a terminal device perception node, and each access network device performing perception may be referred to as an access network device perception node.

[0153] Optionally, when the second network device determines that the perception mode of the first perception task is the mode in which the access network device performs perception, the second network device determines the candidate access network device that performs the first perception task based on the relevant information of the first perception task. Determining the first network device based on the candidate access network device that performs the first perception task may refer to: when the second network device determines that the perception mode of the first perception task is the mode in which the access network device performs perception, the second network device determines one or more candidate access network devices that perform the first perception task based on the relevant information of the first perception task, and each of the one or more candidate access network devices that perform the first perception task is regarded as each first network device.

[0154] Determining one or more candidate access network devices for performing the first perception task based on the relevant information of the first perception task may include: determining a target perception area based on the relevant information of the first perception task, and determining one or more candidate access network devices for performing the first perception task based on the target perception area and the perception mode performed by the access network device. Here, the candidate access network device may refer to an access network device perception node.

[0155] Regarding determining the target perception area based on the relevant information of the first perception task, the second position of the target perception object can be determined based on the relevant information of the target perception object of the first perception task, and the target perception area at the target granularity can be determined based on the second position of the target perception object, or the target perception area at each of the one or more granularities corresponding to the target perception object can be determined. Alternatively, determining the target perception area based on the relevant information of the first perception task can be directly using the target perception area of ​​the first perception task contained in the relevant information of the first perception task as the target perception area. Among them, the specific processing of determining the target perception area at the target granularity based on the second position of the target perception object, or determining the target perception area at each of the one or more granularities corresponding to the target perception object, is the same as the aforementioned embodiment and will not be repeated.

[0156] The determination of one or more candidate access network devices that perform the first perception task based on the target perception area and the mode in which the access network device performs perception may refer to one of the following: when the mode in which the access network device performs perception is specifically a mode in which a single access network device performs perception, determining a candidate access network device that performs the first perception task from all candidate access network devices located within the target perception area; when the mode in which the access network device performs perception is specifically a mode in which multiple access network devices collaborate to perform perception, determining multiple candidate access network devices that perform the first perception task from all candidate access network devices located within the target perception area.

[0157] It should be noted that if there is only one candidate access network device performing the first sensing task, that candidate access network device can be directly used as the first network device. If there are multiple candidate access network devices performing the first sensing task, each of the multiple candidate access network devices can be used as the first network device. However, it should be noted that the processing performed by each of the multiple first network devices is the same. Therefore, this embodiment only describes any one of them and does not elaborate on them one by one.

[0158] In the process of the second network device sending the first message to the first network device, it can include: the second network device sends the first message to each first network device respectively. That is, for the mode of self-transmission and self-reception of the access network device or collaborative perception of multiple access network devices, the second network device needs to send the above-mentioned first message to one or more access network devices (i.e., one or more first network devices) participating in the first perception task. The first message is not a perception request or does not carry a perception request, but only carries relevant information of the first perception task. The first message is also only used to obtain relevant information of each electronic device in the target perception area, that is, the first message is only used to request the first network device to identify the UE located in the target perception area. Exemplarily, the first message can be called a UE ID acquisition request in this embodiment.

[0159] Optionally, when the second network device determines that the perception mode of the first perception task is the mode in which the terminal device performs perception, the second network device determines the candidate terminal device that performs the first perception task based on the relevant information of the first perception task, and determines the first network device based on the candidate terminal device that performs the first perception task. This may refer to: when the second network device determines that the perception mode of the first perception task is the mode in which the terminal device performs perception, the second network device determines one or more candidate terminal devices that perform the first perception task based on the relevant information of the first perception task, determines the candidate access network device corresponding to each of the one or more candidate terminal devices, and determines the first network device based on the candidate access network device corresponding to each candidate terminal device.

[0160] The candidate access network device corresponding to any candidate terminal device may refer to the candidate access network device serving the candidate terminal device. Here, the candidate terminal device may refer to a terminal device perception node.

[0161] The determining of one or more candidate terminal devices for performing the first perception task based on the relevant information of the first perception task can be as follows: determining a target perception area based on the relevant information of the first perception task, and determining one or more candidate terminal devices for performing the first perception task based on the target perception area and the mode in which the terminal device performs perception.

[0162] The description of determining the target perception area based on the relevant information of the first perception task is the same as that in the previous embodiment and will not be repeated here.

[0163] The determination of one or more candidate terminal devices for performing the first perception task based on the target perception area and the mode in which the terminal device performs perception may refer to one of the following: when the mode in which the terminal device performs perception is specifically a mode in which a single terminal device performs perception, determining a candidate terminal device for performing the first perception task from all candidate terminal devices located within the target perception area; when the mode in which the terminal device performs perception is specifically a mode in which multiple terminal devices collaborate to perform perception, determining multiple candidate terminal devices for performing the first perception task from all candidate terminal devices located within the target perception area.

[0164] It should be noted that if there is only one candidate terminal device that performs the first perception task, the candidate access network device corresponding to the candidate terminal device can be directly used as the first network device. If there are multiple candidate terminal devices that perform the first perception task, when each candidate terminal device in the multiple candidate terminal devices corresponds to the same candidate access network device, the candidate access network device can be used as the first network device. When the multiple candidate terminal devices correspond to multiple candidate access network devices, the multiple candidate access network devices can be used as multiple first network devices. It should be noted that the processing performed by each of the multiple first network devices is the same, so this embodiment only describes any one of them and does not elaborate on them one by one.

[0165] The process of the second network device sending the first message to the first network device may include: the second network device sending the first message to each first network device respectively. That is, in the terminal device self-transmitting and self-receiving mode or the collaborative perception mode of multiple terminal devices, the second network device uses the candidate access network device corresponding to each candidate terminal device among one or more candidate terminal devices participating in the first perception task as each first network device, and sends the first message to each first network device. Exemplarily, the first message in this embodiment may be referred to as a UE ID acquisition request.

[0166] Optionally, when the second network device determines that the perception mode of the first perception task is a mode in which the access network device and the terminal device collaborate to perform perception, the second network device determines, based on the relevant information of the first perception task, a candidate access network device that performs the first perception task and a candidate terminal device that performs the first perception task. Determining the first network device based on the candidate access network device that performs the first perception task and the candidate terminal device that performs the first perception task may refer to: when the second network device determines that the perception mode of the first perception task is a mode in which the access network device and the terminal device collaborate to perform perception, the second network device determines, based on the relevant information of the first perception task, one or more candidate access network devices that perform the first perception task and one or more candidate terminal devices that perform the first perception task, determines the candidate access network device corresponding to each of the one or more candidate terminal devices, and determines one or more first network devices based on the one or more candidate access network devices that perform the first perception task and the candidate access network devices corresponding to each candidate terminal device that performs the first perception task.

[0167] The determination of one or more candidate access network devices that perform the first perception task and one or more candidate terminal devices that perform the first perception task based on the relevant information of the first perception task can be as follows: determining the target perception area based on the relevant information of the first perception task, and determining one or more candidate access network devices that perform the first perception task and one or more candidate terminal devices that perform the first perception task based on the target perception area and the mode in which the access network device and the terminal device collaborate to perform perception. The description of determining the target perception area based on the relevant information of the first perception task is the same as that in the aforementioned embodiment and will not be repeated here.

[0168] The determination of one or more candidate access network devices that perform the first perception task and one or more candidate terminal devices that perform the first perception task based on the target perception area and the mode of collaborative perception between the access network device and the terminal device may refer to one of the following: determining one or more candidate terminal devices that perform the first perception task from all candidate terminal devices located within the target perception area, and determining one or more candidate access network devices that perform the first perception task from all candidate access network devices located within the target perception area.

[0169] It should be noted that if there is only one candidate terminal device that performs the first perception task, the candidate access network device corresponding to the candidate terminal device can be directly used as a first network device. If there are multiple candidate terminal devices that perform the first perception task, when each candidate terminal device in the multiple candidate terminal devices corresponds to the same candidate access network device, the candidate access network device can be used as a first network device. When the multiple candidate terminal devices correspond to multiple candidate access network devices, the multiple candidate access network devices can be used as multiple first network devices. It should be noted that the processing performed by each of the multiple first network devices is the same, so this embodiment only describes any one of them and does not elaborate on them one by one.

[0170] In the process of the second network device sending the first message to the first network device, it can include: the second network device sends the first message to each first network device respectively. That is, in the mode where the access network device and the terminal device collaborate to perform perception, the second network device will use the candidate access network device corresponding to each candidate terminal device in the one or more candidate terminal devices participating in the first perception task as each first network device, and the second network device will also use the one or more candidate access network devices participating in the first perception task as each first network device, and send the above-mentioned first message to each first network device. Exemplarily, the first message can be called a UE ID acquisition request in this embodiment.

[0171] In this embodiment, after the first network device receives the first message, the first network device determines one or more electronic devices within the target perception area based on relevant information of the first perception task.

[0172] Optionally, the relevant information of the first perception task only includes the relevant information of the target perception object of the first perception task. Accordingly, the first network device determines one or more electronic devices within the target perception area based on the relevant information of the first perception task, which may include: the first network device uses its own service area as the target perception area; the first network device determines one or more electronic devices different from the target perception object from one or more candidate devices located in the target perception area. The specific description of this processing is the same as that of the aforementioned embodiment, except that the first network device is a first access network device, which will not be repeated here.

[0173] Alternatively, the first network device determines one or more electronic devices within the target perception area based on the relevant information of the first perception task, including: the first network device determines the second position of the target perception object based on the relevant information of the target perception object; the first network device determines the target perception area at the target granularity corresponding to the target perception object based on the second position of the target perception object and the target granularity; the first network device determines one or more electronic devices different from the target perception object from one or more candidate devices within the target perception area at the target granularity corresponding to the target perception object. The specific description of this processing is the same as that of the aforementioned embodiment, except that the first network device is a first access network device, which will not be repeated here.

[0174] Optionally, the relevant information of the first perception task only includes the target perception area of ​​the first perception task. The first network device determines one or more electronic devices within the target perception area based on the relevant information of the first perception task, including: the first network device determines one or more candidate devices located in the target perception area, and uses the one or more candidate devices as the one or more electronic devices. The above processing is the same as the above embodiment and will not be repeated. The difference from the above embodiment is that the first network device is a first access network device and will not be repeated.

[0175] In this embodiment, the second message may carry relevant information of each electronic device in the target sensing area. Exemplarily, the second message may be called a UE ID acquisition response in this embodiment. The detailed description of the second message is the same as that in the previous embodiment and will not be repeated here.

[0176] After SF selects the perception node (UE or RAN) to perform the perception task, SF can initiate a query request to all RAN nodes participating in the perception task, or the RAN node currently serving the UE participating in the perception task, and the RAN node reports the UE ID it is currently serving to SF. In conjunction with Figure 8, taking the first network device as RAN and the second network device as SF as an example, the processing scheme provided by the above embodiment is exemplified. As shown in Figure 8, SF can select a suitable RAN and UE based on the relevant information of the first perception task (such as the identification or location information of the target perception area / target perception object), and request the RAN perception node or the RAN serving the UE perception node to assist in identifying the UE affected by the first perception task. The specific process is as follows:

[0177] In step 801, the SF sends a UE ID acquisition request to the RAN. The UE ID acquisition request carries the target UE ID and AoI. In addition, although not shown in FIG8 , the UE ID acquisition request may also carry the first position of the target sensing object.

[0178] Specifically, according to different sensing modes determined by the sensing request, the UE ID acquisition request message may be sent to different RANs according to the following situations:

[0179] a) For the RAN autonomous and multi-RAN collaborative sensing mode, the SF needs to send a UE ID acquisition request to one or more RAN sensing nodes participating in the first sensing task; that is, each of the one or more RAN sensing nodes is regarded as the first network device. It should be understood that for the sake of simplicity, Figure 8 only illustrates a scenario in which one RAN sensing node is used as the first network device. In actual processing, there can be multiple RANs in Figure 8, but the processing performed by each RAN is the same, so this example will not be detailed one by one.

[0180] b) For the sensing mode in which the UE transmits and receives data independently and multiple UEs collaborate, the SF needs to determine one or more UE sensing nodes that participate in the first sensing task and send a UE ID acquisition request to one or more RAN nodes serving the one or more UE sensing nodes; that is, each of the one or more RAN nodes serving the one or more UE sensing nodes is used as the first network device. It should be understood that for the sake of simplicity, Figure 8 only illustrates a scenario in which only one RAN is used as the first network device. In actual processing, there can be multiple RANs in Figure 8, but the processing performed by each RAN is the same, so this example will not be repeated one by one.

[0181] c) For the UE-RAN collaborative perception mode, the SF needs to send a UE ID acquisition request not only to the RAN node participating in the first perception task, but also to the RAN serving the UE node participating in the first perception task. It should be understood that in Figure 8, for simplicity, only one RAN is illustrated as the first network device. The RAN illustrated in Figure 8 can be a RAN perception node or a RAN serving a UE perception node. This example does not elaborate on the processing of each RAN.

[0182] This UE ID acquisition request is the first message in the aforementioned embodiment. For target-oriented sensing tasks, the UE ID acquisition request may include the target UE ID, which can also be replaced with information such as the location of the target object. For area-oriented sensing, the UE ID acquisition request may include the Area of ​​Interest (AoI), which is the target sensing area for the first sensing task. The UE ID acquisition request can be sent to the RAN via the AMF or directly by the SF.

[0183] Step 802: The RAN sends a UE ID acquisition response to the SF. The UE ID acquisition response may carry a list of affected UE IDs.

[0184] Specifically, after receiving the UE ID acquisition request message, the RAN may return all non-target UE IDs it is serving except the target UE to the SF, or return all non-target UE IDs that are different from the target UE or target object and are in the same target perception area as the target UE or target object to the SF, or send all UE IDs within the target perception area to the SF. The UE ID acquisition response may be the second message in the aforementioned embodiment, and may be sent to the SF via the AMF or directly to the SF.

[0185] It should be pointed out that the scenario illustrated in FIG8 also includes UE. The UE illustrated in FIG8 may refer to a UE perception node, of which there may be multiple. For the sake of simplicity, the interaction of the UE perception node is not illustrated in FIG8 .

[0186] The advantage of this embodiment over the example in which the AMF obtains the affected UE ID list is that the processing of obtaining the affected UE ID list through the RAN can more accurately identify non-target UEs that may be affected, thereby reducing the probability of false detection.

[0187] In some possible implementations, after receiving the second message, the second network device may further request perception authorization from one or more electronic devices within the target perception area, that is, request one or more electronic devices within the target perception area to authorize the first perception task (or authorize the first perception task). Exemplarily, requesting perception authorization for one or more electronic devices within the target perception area (for example, referred to as affected UEs) can be divided into three methods: confirming whether authorization is through a signing message, directly confirming whether authorization is by the affected UE, and secondary authorization.

[0188] Optionally, requesting the one or more electronic devices (for example, affected UEs) within the target sensing area to obtain sensing authorization is to confirm whether authorization is obtained through a subscription message.

[0189] After the second network device receives the second message, it also includes: the second network device obtains a signing message of a second device, where the second device is one of one or more electronic devices within the target perception area; the second network device determines whether the second device authorizes the first perception task based on the signing message of the second device.

[0190] The second network device may be each electronic device located in the target sensing area as a second device, and the same processing as above is performed on each second device, but not described one by one. The second device referred to in the following description may be any device in the aforementioned target sensing area.

[0191] The second network device obtaining the subscription message of the second device may refer to the second network device obtaining the subscription message of the second device from the subscription messages of all candidate devices stored in the second network device based on the identification information of the second device; or the second network device selecting the subscription message of the second device from a network element storing the subscription message based on the identification information of the second device. The network element storing the subscription message may be a UDM or a network element of another core network, and these are not exhaustively listed here.

[0192] The second network device determining whether the second device authorizes the first sensing task based on the subscription message of the second device may include: the second network device determining whether the second device authorizes the first sensing task based on the subscription message of the second device and at least one of the identifier of the first sensing task, the content of the first sensing task, the initiating device of the first sensing task, the receiving device specified by the sensing request, and the sensing mode related information of the first sensing task. For example, if the identifier of the sensing task allowed for authorization in the subscription message of the second device includes the identifier of the first sensing task, the second network device determines that the second device authorizes the first sensing task. For another example, if the content of the sensing task allowed for authorization in the subscription message of the second device includes the content of the first sensing task, the second network device determines that the second device authorizes the first sensing task. For another example, if the identifier of the initiating device of the sensing task allowed for authorization in the subscription message of the second device includes the identifier of the initiating device of the first sensing task, the second network device determines that the second device authorizes the first sensing task, and so on. This does not exhaustively enumerate all possible determination methods for determining whether the second device authorizes the first sensing task. The difference between this confirmation through signing message and related technologies is that it is necessary to first obtain the affected UE (i.e., the device in the target area), and then authorize the first perception task based on the signing message of the affected UE, rather than just randomly selecting the signing message of any UE. The method of obtaining the signing message can reuse the existing process, so I will not go into details here.

[0193] Optionally, the request for sensing authorization by one or more electronic devices (for example, affected UEs) within the target sensing area is to directly confirm whether authorization is granted by the affected UEs.

[0194] Each electronic device within the aforementioned target perception area can be divided into the following three different authorization dimensions: authorization to the initiator of the perception task, authorization to perceive the content, and authorization to assist in perception.

[0195] Authorization for the initiator of a sensing task, i.e., authorization for the device initiating the sensing task, can refer to whether a UE (i.e., any device within the target sensing area) is allowed to execute a sensing task initiated by a certain AF, UE, RAN, or core network element. Authorization for sensing content, i.e., whether a UE (i.e., any device within the target sensing area) is allowed to perform a certain type of sensing task or a sensing task with a certain sensing accuracy. Authorization for assisting sensing, i.e., whether a UE (i.e., any device within the target sensing area) is willing to assist other UEs, RAN, and other sensing nodes in sensing the sensing target.

[0196] After the second network device receives the second message, it also includes: the second network device sends a fourth message to the second device, wherein the fourth message is used to request the second device to authorize the first perception task, and the second device is one of the one or more electronic devices within the target perception area; the second network device receives a response message to the fourth message sent by the second device, wherein the response message to the fourth message is used to indicate whether the second device authorizes the first perception task.

[0197] The second network device may be each electronic device located in the target sensing area as a second device, and the same processing as above is performed on each second device, but not described one by one. The second device referred to in the following description may be any device in the aforementioned target sensing area.

[0198] The second network device sending the fourth message to the second device may refer to the second network device sending the fourth message to the second device via the first core network device and the access network device corresponding to the second device. Correspondingly, the second network device receiving a response message to the fourth message sent by the second device may refer to the second network device receiving, via the first core network device, a response message to the fourth message sent by the second device, which is forwarded by the access network device corresponding to the second device. The first core network device may include an AMF, or may be other core network devices, which are not exhaustively listed here.

[0199] Alternatively, the second network device sending the fourth message to the second device may refer to the second network device sending the fourth message to the second device via the access network device corresponding to the second device. Correspondingly, the second network device receiving a response message to the fourth message sent by the second device may refer to the second network device receiving a response message to the fourth message sent by the second device via the access network device corresponding to the second device.

[0200] The fourth message may be referred to as a perception authorization request, and the response message to the fourth message may be referred to as a perception authorization response.

[0201] The fourth message carries at least one of the following: identification information of the second device, identification of the first perception task, content of the first perception task, identification information of the initiating device of the first perception task, identification information of the receiving device specified by the perception request, information related to the perception mode of the first perception task, and information related to the perception measurement data required for the first perception task. The identification information of the second device may refer to the ID of the second device. The detailed description of the ID is the same as that of the aforementioned embodiment and is not repeated here.

[0202] The content of the first perception task includes at least one of the following: the type of the first perception task, the requirements of the first perception task, and the execution device of the first perception task. The type of the first perception task may include at least one of the following: dynamic map, vehicle speed detection, vehicle tracking, emergency notification, vehicle audit, etc. It should be understood that this is merely an example, and in actual processing, the type of the first perception task may also be other types, but this is not an exhaustive list.

[0203] The requirements of the first perception task, which can also be referred to as the business requirements of the first perception task, can include at least one of the following: the perception resolution of the first perception task, the perception accuracy of the first perception task, the frame rate of the first perception task, the duration of the first perception task, the latency of the first perception task, and the relevant information of the first perception task. The description of the relevant information of the first perception task is the same as that in the aforementioned embodiment, that is, it can include relevant information of the target perception object (such as information called the perceived target) or the target perception area (also called target area information), which will not be repeated here.

[0204] The execution device of the first perception task may include: identification information of the perception node that executes the first perception task, wherein the description of the identification information is the same as that in the aforementioned embodiment and will not be repeated. The perception node of the first perception task may include: an access network device perception node and / or a terminal device perception node, and the relevant descriptions of the access network device perception node and the terminal device perception node are the same as those in the aforementioned embodiment and will not be repeated. It should be understood that the execution device of the first perception task may be determined on the second network device side based on the aforementioned perception request, and the specific determination method has been detailed in the aforementioned embodiment and will not be repeated; alternatively, the execution device of the first perception task may be carried in the perception request, which is not limited in this embodiment.

[0205] The perception mode related information includes at least one of the following: a mode in which the access network device performs perception, a mode in which the terminal device performs perception, a mode in which the access network device and the terminal device collaborate to perform perception, the second device acting as a transmitter of a perception signal, and the second device acting as a receiver of a perception signal.

[0206] Exemplarily, the perception mode-related information of the first perception task may include any one of a mode in which the access network device performs perception, a mode in which the terminal device performs perception, and a mode in which the access network device and the terminal device collaborate to perform perception. The description of the above-mentioned various modes has been detailed in the aforementioned embodiments and will not be repeated here. Furthermore, the perception mode-related information of the first perception task may include at least one of the following: the second device acts as a transmitter of the perception signal, and the second device acts as a receiver of the perception signal. That is, in the mode in which the terminal device performs perception, or the mode in which the access network device and the terminal device collaborate to perform perception, the second device may act as a transmitting terminal device of the perception signal or as a receiving terminal device of the perception signal, or the second device may act only as a transmitting terminal device of the perception signal or as a receiving terminal device of the perception signal. The method for determining whether the second device acts as a transmitter of the perception signal and / or a receiver of the perception signal may be related to the aforementioned perception mode, the specific location of the second device, the specific location of the target perception object, etc., and is not limited here.

[0207] The receiving device specified by the perception request may refer to the consumer of the first perception task that ultimately obtains the perception result. It should be understood that the receiving device specified by the above perception request may be carried in the perception request.

[0208] The identification information of the initiating device of the first perception task may specifically refer to the identification information of the first device. The detailed description of the first device is the same as that of the aforementioned embodiment and will not be repeated here. The receiving device specified by the perception request and the initiating device of the first perception task may be the same device, or the receiving device specified by the perception request and the initiating device of the first perception task may be different devices, all of which are within the protection scope of this embodiment, and all possibilities are not exhaustively enumerated here. It should be noted that unless otherwise specified below, the initiating device of the first perception task has the same meaning as the first device and will not be repeated.

[0209] Exemplarily, if the fourth message is used to request the second device to authorize the initiator of the first sensing task, the fourth message may carry the identification information of the initiator of the first sensing task. Furthermore, the fourth message may also carry at least one of the following: the identification of the second device, the identification of the first sensing task, the content of the first sensing task, and the receiving device specified in the sensing request. Exemplarily, if the fourth message is used to request the second device to authorize the content of the first sensing task, the fourth message may carry the content of the first sensing task. Further, the fourth message may also carry at least one of the following: the identification information of the second device, the identification of the first sensing task, the identification information of the initiator of the first sensing task, and the identification information of the receiving device specified in the sensing request. Exemplarily, if the fourth message is used to request the second device to authorize assisted sensing of the first sensing task, the fourth message may carry information related to the sensing mode of the first sensing task. The sensing mode-related information may include at least one of the following: the second device acting as the transmitter of the sensing signal, the second device acting as the receiver of the sensing signal, and the sensing mode-related information may also include one of the following: the sensing mode performed by the access network device, the sensing mode performed by the terminal device, or the sensing mode performed collaboratively by the access network device and the terminal device. Furthermore, the fourth message may also carry at least one of the following: identification information of the second device, identification of the first perception task, content of the first perception task, identification information of the initiating device of the first perception task, and identification information of the receiving device specified by the perception request.

[0210] The response message to the fourth message can be used to indicate that the second device does not authorize the first perception task, or to indicate that the second device authorizes the first perception task. The specific content of whether the second device authorizes the first perception task, as indicated by the response message to the fourth message, is related to the authorization content requested by the fourth message. For example, if the fourth message is used to request the second device to authorize the initiator of the first perception task, the response message to the fourth message can be used to indicate that the second device does not authorize the initiator of the first perception task, or to indicate that the second device authorizes the initiator of the first perception task. For another example, if the fourth message is used to request the second device to authorize the content of the first perception task, the response message to the fourth message can be used to indicate that the second device does not authorize the content of the first perception task, or to indicate that the second device authorizes the content of the first perception task. For another example, if the fourth message is used to request the second device to authorize assisted perception of the first perception task, the response message to the fourth message can be used to indicate that the second device does not authorize assisted perception of the first perception task, or to indicate that the second device authorizes assisted perception of the first perception task.

[0211] Furthermore, if the response message to the fourth message is used to indicate that the second device does not authorize the first perception task, the response message to the fourth message may carry the reason for the second device's rejection. Exemplarily, the reason for the second device's rejection may include at least one of the following: refusal to authorize the content of the first perception task, refusal to authorize the initiating device of the first perception task to perceive it, refusal to assist in perceiving the first perception task, etc. The reason for the second device's rejection may also be related to the specific content of the authorization requested by the fourth message. For example, if the fourth message is used to request the second device to authorize the initiating device of the first perception task, the response message to the fourth message may be used to indicate that the second device does not authorize the initiating device of the first perception task, and the reason for the rejection is that the current perception initiator is not allowed to perceive it. For another example, if the fourth message is used to request the second device to authorize the content of the first perception task, the response message to the fourth message may be used to indicate that the second device does not authorize the content of the first perception task, and the reason for the rejection may be refusal to authorize the type of the first perception task, refusal to authorize the requirements of the first perception task, etc. For another example, if the fourth message is used to request authorization for the second device to assist in the first sensing task, the response message to the fourth message may be used to indicate that the second device does not authorize assistance in the first sensing task, and the rejection reason may be a rejection of assisting in the first sensing task. It should be understood that the above is merely an example, and in actual processing, more rejection reasons may be included, which are not exhaustive here.

[0212] In conjunction with Figure 9, the processing scheme provided by the above embodiment is exemplified. SF obtains a list of affected UE IDs. Taking the non-target UE ID included in the list as an example, the specific embodiment of SF's request for perception authorization of the non-target UE is as follows: For the non-target UE, there are three methods: confirmation of authorization through a contract message, direct confirmation to the non-target UE, and secondary authorization. The difference between confirmation through a contract message and the prior art is that it is necessary to obtain the contract message of the non-target UE to authorize the perception task, rather than just verifying the contract message of the target UE. The method of obtaining the contract message can reuse the existing process, so I will not go into details here.

[0213] The privacy protection of non-target UEs in the perception task can be divided into the following three different authorization dimensions: authorization of the perception task initiator, that is, whether a certain UE allows a certain AF, UE, RAN, or core network element to initiate the perception task; authorization of the perception content, that is, whether a certain UE allows a certain type of perception task or a perception task with a certain perception accuracy to perceive it; authorization of assisting perception, that is, whether a certain UE is willing to assist other UEs, RAN, and other perception nodes to perceive the perception target.

[0214] As shown in Figure 9, when the SF requests authorization from the non-target UE, the non-target UE can be queried from the above three dimensions respectively. The second network device is SF, any non-target UE is the second device, the fourth message is the perception authorization request, the response message of the fourth message is the perception authorization response, and the access network device corresponding to the second device is represented as RAN. The second device is exemplarily represented as the second UE in Figure 9 as an example. The specific process is as follows:

[0215] In step 901, the SF sends a perception authorization request to the RAN serving the second UE through the AMF or directly. The request message may include at least one of the following information: the second UE ID, the identifier of the first perception task (i.e., the Task ID in FIG9 ), the content of the first perception task (i.e., the perception content in FIG9 ), the ID of the initiating device of the first perception task (i.e., the perception initiator in FIG9 ), etc. Among them, the second UE ID is the identification information of the second UE that needs to authorize the perception task, the content of the first perception task includes the type of the first perception task, the perception accuracy, the resolution, the duration, and other service requirements, and the initiating device of the first perception task is the initiator of the current perception task or the perception task consumer that needs to obtain the perception result in the end, which may be the first UE ID, the AF ID, or the core network element identifier in the aforementioned embodiment.

[0216] In step 902, after receiving the awareness authorization request, the RAN forwards the awareness authorization request to the non-aware target UE (ie, the second UE) indicated by the second UE ID in the message.

[0217] In step 903, after receiving the sensing authorization request, the second UE informs the network side of whether it agrees to authorize the current first sensing task through a sensing authorization response. The sensing authorization response includes information indicating whether authorization is granted. If authorization is denied, it may also include the reason for the authorization failure, such as the fact that sensing content such as a certain service type or sensing service requirement is not allowed, or that the current sensing initiator is not allowed to sense it.

[0218] In step 904, the RAN forwards the received perception authorization response to the SF via the AMF or directly sends it to the SF.

[0219] It should be understood that the processing flow of whether the second UE is willing to assist in perception is similar to the above process. The difference is that in the perception assistance request message, in addition to the second UE ID, perception task identifier Task ID, perception content, and the initiator of the perception task, it can also include the perception mode as shown in Figure 9 (that is, the perception mode related information of the first perception task in the aforementioned embodiment), such as multi-UE collaboration mode, UE self-transmission and self-reception mode, UE assisted RAN mode, and the second UE as the sender, receiver, or both sender and receiver of the perception signal.

[0220] Requesting non-target UEs to perform perception authorization avoids the leakage of non-target UEs' privacy data. Compared with authorization based on contract messages, directly requesting authorization from UEs can obtain the latest user permission, satisfying the user's dynamically changing perception permission level in different scenarios, locations, and time periods. Avoids privacy leakage caused by untimely updates of contract messages when user perception permission changes. In addition, non-target UEs have different willingness to assist in perception in different scenarios. For example, when carrying a large number of services, there are not enough resources allocated to perception tasks. Directly performing assisted perception authorization on non-target UEs avoids the problem of non-target UEs having their resources preempted by perception tasks when carrying other services. In addition, more refined perception authorization granularity can make user authorization decisions more flexible.

[0221] Optionally, requesting the perception authorization for one or more electronic devices (for example, affected UEs) within the target perception area is a secondary authorization.

[0222] Before the second network device sends the fourth message to the second device, the method also includes: the second network device selects the second device that meets the preset conditions from the one or more electronic devices, wherein the preset conditions include that the perception measurement data obtained by performing the second perception task can be reused by the first perception task.

[0223] For example, the second network device selects the second device that meets the preset conditions from the one or more electronic devices, which may refer to: the second network device determines the i-th device that performs other perception tasks from the one or more electronic devices, takes the other perception task as the second perception task, obtains the perception measurement data obtained by the i-th device performing the second perception task, and determines whether the preset condition that the perception measurement data obtained by performing the second perception task can be reused by the first perception task is met; if it is met, the i-th device is used as the second device; i is a positive integer; if not, the i+1-th device that performs other perception tasks is continued to be determined from the one or more electronic devices, and the above processing is continued, which will not be repeated. Among them, the second perception task may refer to other perception tasks that the second device has historically performed, or other perception tasks that the second device is currently performing. As long as the second perception task is different from the first perception task, it is within the protection scope of this embodiment; in addition, the second device performing other perception tasks may refer to the second device acting as a sending device of perception signals of other perception tasks, and / or the second device acting as a receiving device of perception signals of other perception tasks.

[0224] The method for determining whether the perception measurement data obtained by executing the second perception task can be reused by the first perception task may include: determining whether the relevant information of the perception measurement data obtained by executing the second perception task matches the relevant information of the perception measurement data required by the first perception task.

[0225] The relevant information about the perceptual measurement data required for the first perceptual task includes at least one of the following: the category of the perceptual measurement data required for the first perceptual task, the accuracy of the perceptual measurement data required for the first perceptual task, and the size of the perceptual measurement data required for the first perceptual task. In other words, the determination of whether the perceptual measurement data obtained by executing the second perceptual task can be reused by the first perceptual task may include at least one of the following: determining whether the category of the perceptual measurement data obtained by executing the second perceptual task is the same as the category of the perceptual measurement data required for the first perceptual task; determining whether the accuracy of the perceptual measurement data obtained by executing the second perceptual task is the same as the accuracy of the perceptual measurement data required for the first perceptual task; and determining whether the size of the perceptual measurement data obtained by executing the second perceptual task is the same as the size of the perceptual measurement data required for the first perceptual task.

[0226] It should be pointed out that the number of second devices selected based on the above processing method can be one or more, all of which are within the protection scope of this embodiment. For the sake of simplicity of description, the second device below may refer to any one of the one or more second devices that meet the preset conditions.

[0227] The fourth message is used to request the second device to authorize the first perception task to reuse the perception measurement data obtained by performing the second perception task; the response message of the fourth message is used to indicate whether the second device authorizes the first perception task to reuse the perception measurement data obtained by performing the second perception task.

[0228] In this case, the aforementioned fourth message carries at least relevant information about the perception measurement data required for the first perception task. Here, the relevant information about the perception measurement data required for the first perception task is the same as that in the aforementioned embodiment, and will not be repeated. Exemplarily, in addition to carrying relevant information about the perception measurement data required for the first perception task, the fourth message may also carry at least one of the following: identification information of the second device, identification of the first perception task, content of the first perception task, identification information of the initiating device of the first perception task, identification information of the receiving device specified by the perception request, and information related to the perception mode of the first perception task. Among them, the receiving device specified by the perception request may also be a data open object. The detailed description of the above content is the same as that in the aforementioned embodiment, so it will not be repeated.

[0229] The response message of the fourth message is used to indicate that the second device does not authorize the first perception task to reuse the perception measurement data obtained by performing the second perception task, or is used to indicate that the second device authorizes the first perception task to reuse the perception measurement data obtained by performing the second perception task.

[0230] After the second network device receives the response message of the fourth message sent by the second device, it also includes: when the response message of the fourth message is used to indicate that the second device authorizes the first perception task to reuse the perception measurement data obtained by performing the second perception task, the second network device obtains the perception result of the first perception task based on the perception measurement data obtained by the second device performing the second perception task, and sends the perception result of the first perception task to the receiving device specified by the perception request. Exemplarily, sending the perception result of the first perception task to the receiving device specified by the perception request may refer to the second network device sending a perception response to the receiving device specified by the perception request, and the perception response carries the perception result of the first perception task.

[0231] In addition, in the case where the response message of the fourth message is used to indicate that the second device does not authorize the first perception task to reuse the perception measurement data obtained by performing the second perception task, the response message of the fourth message may also carry a rejection reason, and the rejection reason may be similar to the aforementioned embodiment, and will not be repeated here. In the case where the response message of the fourth message is used to indicate that the second device does not authorize the first perception task to reuse the perception measurement data obtained by performing the second perception task, the aforementioned second network device may also send a perception response to the receiving device specified by the perception request, and the perception response is used to indicate that the first perception task is not authorized to use the perception measurement data obtained by other perception tasks; or, the aforementioned second network device may also control the re-perform of the perception measurement to obtain new perception measurement data, and subsequent processing will not be repeated.

[0232] The fourth message may be referred to as a perception data open authorization request. The response message to the fourth message may be a perception authorization response.

[0233] In conjunction with Figure 10, the processing scheme provided by the above embodiment is exemplified. In Figure 10, the second network device is SF, any non-target UE is the second device, the fourth message is the perception data open authorization request, the response message of the fourth message is the perception authorization response, the access network device corresponding to the second device is represented as RAN, and the second device is exemplarily represented as the second UE in Figure 10 as an example. When SF receives a perception request (which may be a perception request sent by the initiating device of the aforementioned first perception task), it is found that the same or similar perception task (i.e., the aforementioned second perception task) has been or is currently being performed, and the perception data collected by performing the second perception task can be reused in the current perception task (i.e., the first perception task), and it is necessary to request a secondary authorization from the second UE (i.e., the aforementioned second device) to which the perception data belongs. The second UE ID in this scenario can be the second UE ID recorded in the SF, or it can be any one or more second UE IDs of one or more electronic devices in the target perception area that SF requests nodes such as RAN and AMF to assist in obtaining. The specific process is as follows:

[0234] Step 1001: SF receives a perception request, which includes at least perception content and a perception initiator.

[0235] In Figure 10, the device sending the perception request is represented as a Consumer. This Consumer can be the receiving device specified by the perception request and / or the device initiating the first perception task. Exemplarily, the device initiating the first perception task can include one of the following: an AF, a first UE, a RAN that initiates the first perception task, or a core network element that initiates the first perception task.

[0236] The perception request may include the perception content and the identification information of the perception initiator. The perception content, i.e., the content of the first perception task of the aforementioned embodiment, may include at least one of the following: the business type of the first perception task (such as dynamic map, vehicle speed detection, vehicle tracking, emergency notification, vehicle audit), the requirements of the first perception task (perception resolution, perception accuracy, frame rate, duration, target area information, latency, perceived target information such as vehicle type, vehicle identification, location information), designated perception node information (i.e., the information of the execution device of the first perception task, such as the UE perception node); the target area information (i.e., the target perception area), the perceived target information (i.e., the identification information of the target perception object and / or the first position of the target perception object) may also be included in the relevant information of the first perception task, or may be included in the requirements of the first perception task, which is not limited here.

[0237] Step 1002: The SF sends a perception data open authorization request to the RAN corresponding to the second UE.

[0238] Specifically, the SF determines whether the perception measurement data collected by the same or similar perception task (second perception task) that it has performed or is currently performing can be reused (i.e., determine whether the aforementioned preset conditions are met). At this time, the SF still needs to confirm authorization with the owner of the perception measurement data, such as the non-perception target UE (i.e., the second UE). The SF needs to send a perception data open authorization request to the above-mentioned second UE. The request message contains the second UE ID, Task ID (i.e., the identifier of the first perception task), perception measurement data description information (i.e., relevant information about the perception measurement data), perception content (i.e., the content of the first perception task), and the perception initiator (i.e., the ID of the initiating device of the first perception task) or the identification information of the data open object. The description information of the perception measurement data is used to inform the UE of the category, accuracy, size, etc. of the data that needs to be opened; the perception content includes business requirements such as the type of perception task, perception accuracy, resolution, duration, etc., which are used to inform the UE of the purpose of opening the data; and the perception discoverer or data open object is used to inform the UE which functional entity is using its perception measurement data. The perception data open authorization request can be forwarded by the AMF to the RAN or sent directly to the RAN, which can refer to the RAN corresponding to the second UE.

[0239] Step 1003: The RAN forwards the received sensing data open authorization request to the second UE.

[0240] In step 1004, after receiving the sensing authorization request, the second UE informs the network side through a sensing authorization response whether it agrees to authorize the first sensing task to reuse the sensing measurement data obtained by performing the second sensing task. The sensing authorization response includes an indication of whether the first sensing task is authorized to reuse the sensing measurement data obtained by performing the second sensing task. If authorization is not granted, it may also include the reason for the authorization failure, such as the disallowance of sensing content such as a certain service type or sensing service requirement, or the disallowance of the current sensing initiator from sensing the same service.

[0241] In step 1005, the RAN forwards the received perception authorization response via the AMF or directly sends it to the SF.

[0242] Step 1006: The SF sends a perception response to the Consumer. The perception response may include a perception result calculated from the perception measurement data.

[0243] Exemplarily, if the SF is authorized by the second UE, it calculates the perception result based on the perception measurement data and sends it to the perception task initiator. If the SF is not authorized by the second UE, it can inform the task initiator in a response message that the perception task is not authorized, or re-perform the perception measurement to obtain new data.

[0244] This example can perform secondary authorization processing when the perception measurement data needs to be reused, thereby preventing unauthorized third parties from obtaining the perception measurement data obtained by user measurements for unknown purposes, and eliminating the possibility of unauthorized third parties obtaining perception results by sending the same perception request as the authorized perception task initiator.

[0245] It can be seen that by adopting the solution provided by the above embodiment, each electronic device in the target perception area can be identified. Since the target perception area is related to the first perception task, identifying each electronic device in the target perception area means identifying each electronic device affected by the perception task, thereby avoiding the problem in related technologies that only the target perception object specified by the perception task is identified for authorization, but the privacy of other electronic devices affected by the perception task cannot be protected, thereby ensuring the privacy security of each electronic device affected by the perception task in the target perception area.

[0246] Figure 11 is a schematic flow chart of a communication method according to another embodiment of the present application. The method includes at least part of the following contents.

[0247] S1110. The second network device sends a fifth message to the third device, wherein the fifth message is used to request the third device to authorize the first sensing task;

[0248] S1120. The second network device receives a response message to the fifth message sent by the third device, where the response message to the fifth message is used to indicate whether the third device authorizes the first perception task.

[0249] Figure 12 is a schematic flow chart of a communication method according to another embodiment of the present application. The method includes at least part of the following contents.

[0251] S1220. The third device sends a response message to the fifth message to the second network device, where the response message to the fifth message is used to indicate whether the third device authorizes the first perception task.

[0252] The second network device is a second core network device with a perception function. The detailed description of the second core network device with a perception function is the same as that in the above embodiment and will not be repeated.

[0253] Before the second network device sends the fifth message to the third device, it may also include: the second network device receives a perception request.

[0254] The second network device receiving the perception request may be: the second network device receiving the perception request sent by the first device; or the second network device receiving the perception request sent by the first device through the first network device. Here, the first network device is a first core network device or a second access network device. The first core network device may refer to an AMF, or may be other core network devices. As long as the core network device can execute the solution provided by this embodiment, it is within the protection scope of this embodiment, and no exhaustive list is given here.

[0255] The aforementioned first device may be one of the following: a first terminal device, a first access network device, a first server, or a third core network device. The first device may be a device that initiates perception, that is, the first device is the initiating device of the first perception task. The first terminal device may be a terminal device that initiates perception; the first access network device may be an access network device that initiates perception; the first server may be a server that initiates perception, and the server may be an AF (Application Function) network element, or may be other network elements with service functions, which are not exhaustive here; the third core network device may be a core network device that initiates perception. It should be understood that as long as the core network device has the function of initiating perception, it is within the protection scope of this embodiment, and not all possible core network devices that initiate perception are limited here.

[0256] The specific manner in which the second network device directly receives the perception request sent by the first device, or the specific manner in which the second network device receives the perception request sent by the first device through the first network device, has been described in detail in the various embodiments of the aforementioned communication method and will not be repeated here.

[0257] The above-mentioned perception request may carry relevant information of the first perception task. The specific description of the relevant information of the first perception task is the same as the detailed description in the various embodiments of the aforementioned communication method and is not repeated here. The perception request may also include at least one of the following: the identifier of the first perception task, the content of the first perception task, the identification information of the initiating device of the first perception task, the identification information of the receiving device specified by the perception request, the perception mode related information of the first perception task, and the relevant information of the perception measurement data required for the first perception task.

[0258] In some possible implementations, before sending the fifth message to the third device, the method further includes: the second network device selects the third device to perform the first perception task based on the perception mode of the first perception task and the target perception area of ​​the first perception task.

[0259] The perception mode of the above-mentioned first perception task may be carried in the perception mode related information of the first perception task of the aforementioned perception request. The perception mode related information of the first perception task may include one of the following: a mode in which the access network device performs perception, a mode in which the terminal device performs perception, and a mode in which the access network device and the terminal device collaborate to perform perception. Among them, the detailed description of the mode in which the access network device performs perception, the mode in which the terminal device performs perception, and the mode in which the access network device and the terminal device collaborate to perform perception are the same as those in the various embodiments of the aforementioned communication method and will not be repeated here.

[0260] The method for determining the target perception area of ​​the above-mentioned first perception task may include: when the perception request carries relevant information of the target perception object of the first perception task, determining the second position of the target perception object based on the relevant information of the target perception object; and determining the target perception area based on the second position of the target perception object. For example, if the relevant information of the target perception object is the identification information of the target perception object, the second position of the target perception object is determined based on the UE context (Context) of all UEs stored locally and the identification information of the target perception object, and based on the second position of the target perception object, at least one of the following is determined: the target perception area under the RA, the target perception area under the TA, the target perception area under the cell, the target perception area under the sector, and the target perception area under a specified radius.

[0261] Alternatively, the method for determining the target perception area of ​​the first perception task may include: directly extracting the target perception area when the perception request carries the target perception area of ​​the first perception task.

[0262] The second network device selects the third device to perform the first perception task based on the perception mode of the first perception task and the target perception area of ​​the first perception task. This may mean that the second network device determines one or more candidate terminal devices and / or one or more candidate access network devices that are located in the target perception area of ​​the first perception task and can perform the first perception task based on the perception mode of the first perception task, and selects the third device to perform the first perception task from the one or more candidate terminal devices and / or one or more candidate access network devices. That is, by adopting the method provided in this example, the device that satisfies the perception mode of the first perception task and is located in the target perception area based on the perception request can be selected as the aforementioned third device. It should be understood that the number of the third devices can be one or more, and the type of the third device can include an access network device or a terminal device. The same processing is performed for each third device, but they are not described one by one. The following embodiments are described by taking any one third device as an example, that is, if there is no special explanation, the third device below can refer to any one of one or more third devices.

[0263] The authorization of the aforementioned third device can be divided into the following three different dimensions: authorization of the initiator of the perception task, authorization of the perception content, and authorization of assisted perception. Among them, the authorization of the initiator of the perception task, that is, the authorization of the initiator of the perception task, can refer to: whether the third device is allowed to execute the perception task initiated by a certain AF, UE, RAN, or core network element. Authorization of perception content, that is, whether the third device allows a certain type of perception task or a perception task of a certain perception accuracy to be perceived by it; authorization of assisted perception, that is, whether the third device is willing to assist other perception nodes such as UE and RAN to perceive the perception target.

[0264] Optionally, the third device is a third access network device.

[0265] The second network device sending the fifth message to the third device may refer to the second network device sending the fifth message to the third access network device via the first core network device. Accordingly, the second network device receiving a response message to the fifth message sent by the third device may refer to the second network device receiving a response message to the fifth message sent by the third access network device via the first core network device. The first core network device may include an AMF or other core network device, which are not exhaustive here. Alternatively, the second network device sending the fifth message to the third device may refer to the second network device sending the fifth message to the third access network device. Accordingly, the second network device receiving a response message to the fifth message sent by the third device may refer to the second network device receiving a response message to the fifth message sent by the third access network device. In other words, in addition to terminal device-assisted perception authorization, in this embodiment, the perception authorization request (i.e., the fifth message) can also be used to request authorization from the access network device perception node. This differs from terminal device-assisted perception in that the perception authorization request (i.e., the fifth message) does not need to be sent to the terminal side; it only needs to be sent to the RAN node participating in the perception task. The authorization of access network device perception nodes is mainly used in the modes of multi-access network device assistance, access network device self-transmission and self-reception, and access network device and terminal device assisting in perception.

[0266] Optionally, the third device is a second terminal device.

[0267] The second network device sends the fifth message to the third device, including: the second network device sends the fifth message to the second terminal device through the fourth access network device, and the fourth access network device serves the second terminal device; the second network device receives a response message to the fifth message sent by the third device, including: the second network device receives a response message to the fifth message sent by the second terminal device through the fourth access network device.

[0268] Optionally, the fifth message may be called a perception authorization request, and the response message to the fifth message may be called a perception authorization response.

[0269] The fifth message carries at least one of the following: identification information of the third device, identification of the first perception task, content of the first perception task, identification information of the initiating device of the first perception task, identification information of the receiving device specified by the perception request, relevant information about the perception mode of the first perception task, and relevant information about the perception measurement data required for the first perception task.

[0270] The identification information of the third device may refer to the network identification and / or ID of the third device. The detailed description of the network identification and ID is the same as that of the various embodiments of the aforementioned communication method, and will not be repeated here.

[0271] The content of the first perception task includes at least one of the following: the type of the first perception task, the requirements of the first perception task, and the device for executing the first perception task. The detailed description of the type of the first perception task, the requirements of the first perception task, and the device for executing the first perception task is the same as that of the various embodiments of the aforementioned communication method and is not repeated here.

[0272] The perception mode related information includes at least one of the following: a mode in which the access network device performs perception, a mode in which the terminal device performs perception, a mode in which the access network device and the terminal device collaborate to perform perception, the third device acting as a transmitter of a perception signal, and the third device acting as a receiver of a perception signal.

[0273] Exemplarily, the perception mode-related information of the first perception task may include any one of a mode in which the access network device performs perception, a mode in which the terminal device performs perception, and a mode in which the access network device and the terminal device collaborate to perform perception. The description of the above-mentioned various modes has been detailed in the aforementioned embodiments and will not be repeated here. Furthermore, the perception mode-related information of the first perception task may include at least one of the following: the third device acts as a transmitter of the perception signal, and the third device acts as a receiver of the perception signal. That is, in the mode in which the terminal device performs perception, or in the mode in which the access network device and the terminal device collaborate to perform perception, the third device may act as a transmitter of the perception signal or as a receiver of the perception signal, or the third device may only act as a transmitter of the perception signal or as a receiver of the perception signal. The method for determining whether the third device acts as a transmitter of the perception signal and / or a receiver of the perception signal may be related to the aforementioned perception mode, the specific location of the third device, the specific location of the target perception object, etc., and is not limited here.

[0274] The receiving device specified by the perception request may refer to the consumer of the first perception task that ultimately obtains the perception result. It should be understood that the receiving device specified by the above perception request may be carried in the perception request.

[0275] The identification information of the initiating device of the first perception task may specifically refer to the identification information of the first device. The detailed description of the first device is the same as that of the aforementioned embodiment and will not be repeated here. The receiving device specified by the perception request and the initiating device of the first perception task may be the same device, or the receiving device specified by the perception request and the initiating device of the first perception task may be different devices, all of which are within the protection scope of this embodiment, and all possibilities are not exhaustively enumerated here. It should be noted that unless otherwise specified below, the initiating device of the first perception task has the same meaning as the first device and will not be repeated.

[0276] For example, if the fifth message is used to request the third device to authorize the initiator of the first perception task, the fifth message may carry the identification information of the initiator of the first perception task. Furthermore, the fifth message may also carry at least one of the following: the identification of the third device, the identification of the first perception task, the content of the first perception task, and the receiving device specified by the perception request.

[0277] For example, if the fifth message is used to request the third device to authorize the content of the first perception task, the fifth message may carry the content of the first perception task. Furthermore, the fifth message may also carry at least one of the following: identification information of the third device, identification information of the first perception task, identification information of the device initiating the first perception task, and identification information of the receiving device specified in the perception request.

[0278] For example, if the fifth message is used to request authorization for a third device to assist in the first perception task, the fifth message may carry information related to the perception mode of the first perception task. Furthermore, the fifth message may also carry at least one of the following: identification information of the third device, identification of the first perception task, content of the first perception task, identification information of the device initiating the first perception task, and identification information of the receiving device specified in the perception request.

[0279] The response message to the fifth message can be used to indicate that the third device does not authorize the first perception task, or to instruct the third device to authorize the first perception task. The specific content of whether the third device authorizes the first perception task, as indicated by the response message to the fifth message, is related to the authorization content requested by the fifth message. For example, if the fifth message is used to request the third device to authorize the initiator of the first perception task, the response message to the fifth message can be used to indicate that the third device does not authorize the initiator of the first perception task, or to instruct the third device to authorize the initiator of the first perception task. For another example, if the fifth message is used to request the third device to authorize the content of the first perception task, the response message to the fifth message can be used to indicate that the third device does not authorize the content of the first perception task, or to instruct the third device to authorize the content of the first perception task. For another example, if the fifth message is used to request the third device to authorize assisted perception of the first perception task, the response message to the fifth message can be used to indicate that the third device does not authorize assisted perception of the first perception task, or to instruct the third device to authorize assisted perception of the first perception task.

[0280] Furthermore, in the case where the response message of the fifth message is used to indicate that the third device does not authorize the first perception task, the response message of the fifth message carries the rejection reason of the third device. Exemplarily, the rejection reason may include at least one of the following: refusal to authorize the content of the first perception task, refusal to authorize the initiating device of the first perception task to perceive it, refusal to assist in perceiving the first perception task, etc. The above-mentioned rejection reason may also be related to the specific content of the authorization requested by the fifth message, which is similar to the fourth message and its corresponding rejection reason in the aforementioned embodiment, and will not be repeated.

[0281] By adopting the above-mentioned method to request the third device to perform perception authorization, the leakage of the privacy data of the third device is avoided. Compared with authorization based on contract messages, directly requesting authorization from the third device can obtain the latest user permission, which meets the user's dynamically changing perception permission level in different scenarios, different places and different time periods. Avoid privacy leakage caused by untimely update of contract messages when user perception permission changes. In addition, the willingness of the third device (such as the second terminal device or the third access network device) to assist in perception is different in different scenarios. For example, when carrying a large number of services, there are not enough resources allocated to the perception task. Directly authorizing the third device to assist in perception avoids the problem of the third device being preempted by the perception task when carrying other services. In addition, a more refined perception authorization granularity can make the user's authorization decision more flexible.

[0282] Optionally, the perception authorization requested by the third device is a secondary authorization.

[0283] Before sending the fifth message to the third device, the method also includes: the second network device determines the perception measurement data required for the first perception task; the second network device selects the third device that meets the preset conditions based on the perception measurement data required for the first perception task, and the preset conditions include: the perception measurement data obtained by performing the second perception task can be reused by the first perception task.

[0284] The perceptual measurement data required for the first perceptual task may be carried by the perceptual request. Exemplarily, the relevant information of the perceptual measurement data required for the first perceptual task includes at least one of the following: the category of the perceptual measurement data required for the first perceptual task, the accuracy of the perceptual measurement data required for the first perceptual task, and the size of the perceptual measurement data required for the first perceptual task.

[0285] The second network device selects the third device that meets the preset conditions based on the perception measurement data required for the first perception task, which may include: the second network device selects the third device that meets the preset conditions from the one or more terminal devices. For example, the second network device determines the kth device that performs other perception tasks from the one or more terminal devices, takes the other perception task as the second perception task, obtains the perception measurement data obtained by the kth device performing the second perception task, and determines whether the preset condition that the perception measurement data obtained by performing the second perception task can be reused by the first perception task is met; if so, the kth device is used as the third device; k is a positive integer; if not, the k+1th device that performs other perception tasks is continued to be determined from the one or more terminal devices, and the above processing is continued, which will not be repeated. Among them, the second perception task may refer to other perception tasks that the third device has historically performed, or other perception tasks that the third device is currently performing. As long as the second perception task is different from the first perception task, it is within the protection scope of this embodiment; in addition, the third device performing other perception tasks may refer to the third device acting as a sending device of perception signals of other perception tasks, and / or the third device acting as a receiving device of perception signals of other perception tasks.

[0286] The method for determining whether the perceptual measurement data obtained by performing the second perceptual task can be reused by the first perceptual task may include: determining whether the relevant information of the perceptual measurement data obtained by performing the second perceptual task matches the relevant information of the perceptual measurement data required by the first perceptual task. In other words, the determination whether the perceptual measurement data obtained by performing the second perceptual task can be reused by the first perceptual task may include at least one of the following: determining whether the category of the perceptual measurement data obtained by performing the second perceptual task is the same as the category of the perceptual measurement data required by the first perceptual task; determining whether the accuracy of the perceptual measurement data obtained by performing the second perceptual task is the same as the accuracy of the perceptual measurement data required by the first perceptual task; and determining whether the size of the perceptual measurement data obtained by performing the second perceptual task is the same as the size of the perceptual measurement data required by the first perceptual task.

[0287] It should be pointed out that the number of third devices selected based on the above processing method can be one or more, all of which are within the protection scope of this embodiment. For the sake of simplicity of description, the third device below may refer to any one of one or more third devices that meet the preset conditions.

[0288] The fifth message is used to request the third device to authorize the first perception task to reuse the perception measurement data obtained by performing the second perception task; after the second network device receives the response message to the fifth message sent by the third device, it also includes: when the response message of the fifth message is used to indicate that the third device authorizes the first perception task to reuse the perception measurement data obtained by performing the second perception task, the second network device obtains the perception result of the first perception task based on the perception measurement data obtained by the third device performing the second perception task, and sends the perception result of the first perception task to the receiving device specified by the perception request.

[0289] In this case, the aforementioned fifth message carries at least relevant information about the perception measurement data required for the first perception task. Here, the relevant information about the perception measurement data required for the first perception task is the same as that in the aforementioned embodiment, and will not be repeated. Exemplarily, in addition to carrying relevant information about the perception measurement data required for the first perception task, the fifth message may also carry at least one of the following: identification information of the third device, identification of the first perception task, content of the first perception task, identification information of the initiating device of the first perception task, identification information of the receiving device specified by the perception request, and information related to the perception mode of the first perception task. Among them, the receiving device specified by the perception request may also be a data open object. The detailed description of the above content is the same as that in the aforementioned embodiment, so it will not be repeated.

[0290] The response message of the fifth message is used to indicate that the third device does not authorize the first perception task to reuse the perception measurement data obtained by performing the second perception task, or is used to indicate that the third device authorizes the first perception task to reuse the perception measurement data obtained by performing the second perception task.

[0291] Exemplarily, sending the perception result of the first perception task to the receiving device specified by the perception request may refer to the second network device sending a perception response to the receiving device specified by the perception request, and the perception response carries the perception result of the first perception task.

[0292] In addition, in the case where the response message of the fifth message is used to indicate that the third device does not authorize the first perception task to reuse the perception measurement data obtained by performing the second perception task, the response message of the fifth message may also carry a rejection reason, and the rejection reason may be similar to the aforementioned embodiment, and will not be repeated here. In the case where the response message of the fifth message is used to indicate that the third device does not authorize the first perception task to reuse the perception measurement data obtained by performing the second perception task, the aforementioned second network device may also send a perception response to the receiving device specified by the perception request, and the perception response is used to indicate that the first perception task is not authorized to use the perception measurement data obtained by other perception tasks; or, the aforementioned second network device may also control the re-perform of the perception measurement to obtain new perception measurement data, and subsequent processing will not be repeated.

[0293] This example can perform secondary authorization processing when the perception measurement data needs to be reused, thereby preventing unauthorized third parties from obtaining the perception measurement data obtained by user measurements for unknown purposes, and eliminating the possibility of unauthorized third parties obtaining perception results by sending the same perception request as the authorized perception task initiator.

[0294] It can be seen that by adopting the solution provided by the above embodiment, the second network device can directly request the third device itself whether to authorize the perception task. Compared with the authorization based on the contract message, this processing method directly requests authorization from the third device to obtain the latest user permission, which satisfies the user's dynamically changing perception permission level in different scenarios, different locations and different time periods, and avoids the privacy leakage problem caused by the untimely update of the contract message when the user's perception permission changes. In addition, the third device's willingness to authorize a certain perception task is different in different scenarios. Therefore, directly requesting authorization from the third device can avoid the problem of the third device being preempted by the perception task when carrying other services. In addition, a more refined perception authorization granularity can make the user's authorization decision more flexible.
