[0004] Currently, the industry is proposing the introduction of a new Sensing Function (SF) logical network element on the core network side to handle sensing services.

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0042] With the increase in application demands, more requirements are placed on the capabilities of communication equipment. For example, terminals and base stations are required to transmit wireless signals to target areas or objects, analyze the received signals, and obtain perception measurement information, thereby realizing perception of the basic environment and target objects, and enabling the network to provide more diverse intelligent services.

[0043] Considering that mobile communication networks naturally possess wireless perception capabilities, integrating communication and perception into the design is a future research direction for networks, namely, communication-perception fusion design. Synaesthesia fusion technology uses wireless signals to perceive targets or states in the surrounding environment. Wireless terminals and / or base stations collect information such as signal strength, channel state, latency, and phase change, and after calculation and processing, output results such as target location and speed. Currently, research on synaesthesia fusion architecture has achieved some results, and the introduction of new SF logical network elements on the core network side has been basically clarified to handle the relevant functions of perception services, while also possessing control plane and user plane processing capabilities. SF logical network elements can be centralized or distributed, and SF logical network elements can also be considered for integration with existing network function (NF) network elements, such as location management function (LMF) network elements to reuse the existing interface between LMF and the fifth generation mobile communication technology (5G) core network for perception interaction.

[0044] As shown in Figure 1, the SF includes the perception control plane function and the perception data plane function. The perception control plane function can interact with existing 5G core network control plane network elements (such as the Network Data Analytics Function (NWDAF), Access and Mobility Management Function (AMF), Unified Data Management Function (UDM), LMF, Policy Control Function (PCF), Network Exposure Function (NEF), etc.), is responsible for control plane message transmission, and provides the address of the perception data plane function to the base station / UE. The perception data plane function is responsible for collecting and analyzing the perception measurement data generated by the terminal or base station, deriving the final perception results, and opening them to the UE or application.

[0045] Research on interawareness fusion design is just beginning. When a UE initiates a sensing service that requires other UEs to perceive it, the SF network element must authenticate the sensing service through the UDM network element. The SF network element then selects an appropriate sensing node based on the UDM's authentication result and factors such as the sensing node's location, load, and capabilities. Although the UDM stores terminal authorization data, the data for each sensing terminal is dynamic. This means that the sensing terminal identified through an authentication query may not be able to perform the sensing service. Furthermore, authenticating only the requesting terminal cannot fully protect the security of the sensing service.

[0046] FIG2 is a schematic diagram of an implementation flow of a perception terminal selection method provided by an embodiment of the present disclosure, wherein the execution subject of the perception terminal selection method is a first network function network element, which may be the SF network element in FIG1. ​​Referring to FIG2, the perception terminal selection method includes:

[0047] S201, receiving a first request; the first request includes perception service request information and information of a requesting terminal that has been authenticated by a second network function network element.

[0048] The sensing service request information includes the sensing service type and the sensing service requirement. The first request may be called a sensing service request.

[0049] For example, the first network function network element receives the perception service request sent by the AMF network element. After receiving the perception service request sent by the requesting terminal, the AMF network element can send a first request to the first network function network element.

[0050] Here, the requesting terminal in the first request received by the first network function network element has been authenticated by the second network function network element, which may be a UDM network element. For example, the AMF network element first authenticates the requesting terminal through the second network function network element, and only sends the perception service request to the first network function network element after the authentication is successful.

[0051] The second network function network element authenticates the requesting terminal, which means performing identity verification on the requesting terminal to determine whether the terminal has the capability to request the perception service type.

[0052] S202: Based on the first request, obtain a list of perception terminals authorized by the second network function network element that meets the perception service request information.

[0053] The list of authorized perception terminals that meet the perception service request information refers to the perception terminals that meet the perception service requirements and are allowed to perform the perception service type.

[0054] If the perception service request does not include perception terminal information, the first network function network element needs to determine a candidate perception terminal set on its own, send an authorization query request for the candidate perception terminal set to the second network function network element, and obtain from the second network function network element a list of authorized perception terminals that meet the perception service request information. The authorized perception terminal list is the candidate perception terminal set or a subset thereof.

[0055] If the perception service request includes information about perception terminals, the perception terminals included in the perception service request are a list of perception terminals that have been authorized by the second network function network element and are in compliance with the perception service request information. For example, the perception service request sent by the requesting terminal to the AMF network element carries information about the perception terminals specified by the requesting terminal. The AMF network element, while authenticating the requesting terminal to the second network function network element, also performs an authorization query on the specified perception terminal, thereby obtaining a list of perception terminals authorized by the second network function network element. The authorized perception terminal list is the specified perception terminal or a subset thereof. The AMF network element obtains the authorized perception terminal list and sends it to the first network function network element through a perception service request. The first network function network element can obtain the list of perception terminals authorized by the second network function network element directly from the perception service request.

[0056] In the disclosed embodiment, a first network function network element receives a first request, the first request including perception service request information and information about a requesting terminal that has been authenticated by a second network function network element, and obtains a list of perception terminals authorized by the second network function network element that meet the perception service request information based on the first request. The disclosed embodiment enhances the functionality of the second network function network element, enabling it to simultaneously query the authentication of the perception requesting terminal and the authorization of the perception detection terminal, thereby achieving security protection for the perception service from perception request to perception detection and ensuring the privacy of the perception service.

[0057] In one embodiment, after obtaining a list of perception terminals authorized by the second network function network element and meeting the perception service request information based on the first request, the method further includes:

[0058] Sending a second request to a perception terminal in the perception terminal list; the second request is used to confirm whether the perception terminal can perform perception detection;

[0059] When the perception confirmation message sent by the perception terminal is received, a perception control request is sent to the perception terminal.

[0060] Here, the second request can be called a perception confirmation request. The control plane function of the first network function network element sends a perception confirmation request to the perception terminal in the authorized perception terminal list to confirm whether the perception terminal can perform perception detection. The perception terminal will confirm whether perception detection is possible based on the load or other information. The control plane function of the first network function network element determines the perception control parameters based on the perception confirmation message replied by the perception terminal, including the distance / speed / angle resolution and accuracy of the perception target, frame rate, duration, perception measurement data reporting cycle, update or end process instructions, etc., and sends a perception control request to the perception terminal that has been confirmed to be able to perform perception detection.

[0061] The embodiment of the present disclosure performs secondary confirmation on whether the perception terminal can perform perception detection. Only the confirmed perception terminals can perform perception detection, thereby ensuring the normal execution of the perception service.

[0062] In one embodiment, receiving the first request includes:

[0063] Receive the first request sent by the AMF network element;

[0064] Correspondingly, the obtaining, based on the first request, a list of perception terminals authorized by the second network function network element and meeting the perception service request information includes:

[0065] If the first request includes the perception terminal list, obtaining the perception terminal list from the first request; the perception terminal list in the first request sent by the AMF network element is obtained by the AMF network element from the second network function network element;

[0066] If the perception service request does not include the perception terminal list, determining a candidate perception terminal set based on the first request;

[0067] Sending an authorization information query request of the candidate perception terminal set to the second network function network element;

[0068] Receive response information sent by the second network function network element, where the response information includes the perception terminal list.

[0069] Among them, if the first request includes a perception terminal list, the perception node in the perception terminal list can be the perception terminal specified by the requesting terminal. The AMF obtains the authorized perception terminal list from the second network function network element and sends it to the first network function network element through a perception service request. The first network function network element can directly obtain the perception terminal list authorized by the second network function network element from the perception service request.

[0070] If the first request does not include a list of sensing terminals, a candidate set of sensing terminals needs to be determined.

[0071] In one embodiment, determining a candidate set of sensing terminals includes:

[0072] Based on the perception service related capability information supported by the perception terminal itself reported by the perception terminal and the perception service request information included in the perception service request, a perception terminal in the candidate perception terminal set is determined.

[0073] Among them, the perception terminal will report the perception service related capabilities it supports to the first network function network element, and then the first network function network element selects a suitable perception terminal by analyzing the perception service type, perception service requirements, perception area and other information in the perception request.

[0074] In one embodiment, after sending the perception control request to the perception terminal, the method further includes:

[0075] Receiving the sensing detection data sent by the sensing terminal;

[0076] Performing perception calculation based on the perception detection data to obtain a perception result;

[0077] The sensing result is sent to the requesting terminal.

[0078] After receiving the perception control request, the perception terminal performs perception detection, obtains perception detection data, and reports the perception detection data to the first network function network element.

[0079] The first network function network element performs perception calculations. Considering that the perception terminal actually performing detection may be a subset of the perception terminal set, the first network function network element needs to analyze and calculate these partial data to achieve the perception results required by the perception request.

[0080] Among them, the first network function network element returns the perception result to AMF, and AMF returns the perception result to the requesting terminal.

[0081] FIG3 is a schematic diagram of an implementation flow of a method for querying authorization of a perception terminal provided by an embodiment of the present disclosure, wherein the execution subject of the authorization query issuance of the perception terminal is a second network function network element, which may be a UDM network element. Referring to FIG3 , the authorization query method of the perception terminal includes:

[0082] S301, receiving a third request; the third request includes perception service request information and requesting terminal information.

[0083] The third request can be called an authorization query request. The third request can be sent by the AMF. For example, first, the UE is requested to initiate a perception service request to the AMF. The perception service request information includes the service type (such as dynamic map, vehicle speed detection, vehicle tracking, emergency notification, vehicle audit), service requirements (perception resolution, perception accuracy, frame rate, duration, area (Area) information, latency, UE information (such as vehicle type, vehicle identification)), etc.; if the UE explicitly specifies the perception node information, the perception service request will also carry the perception node identifier (Identifier, ID). Then, the AMF initiates the third request to the second network function network element. The request information may include perception service request information and UE information. Note that if the requesting UE does not specify the perception UE information, the UE information is the information of the requesting UE; if the requesting UE specifies the perception UE information, the UE information in this step includes the information of the requesting UE and the information of the perception UE.

[0084] S302: Authenticate the requesting terminal based on the awareness service request information and the information of the requesting terminal.

[0085] The second network function network element performs identity authentication and authorization on the requesting terminal.

[0086] S303: If the third request also includes information of the first perception terminal set to be queried, then when the authentication of the requesting terminal is passed, obtain a list of perception terminals in the first perception terminal set to be queried that are authorized by the second network function network element and meet the perception service request information.

[0087] If the third request includes information of the first perception terminal set to be queried, the first perception terminal set may be the perception terminals specified by the requesting terminal. Then, when the authentication of the requesting terminal is passed, it is also necessary to perform an authorization query on the perception terminals in the first perception terminal set to determine whether the perception terminals in the first perception terminal set meet the perception service request information.

[0088] Through the authorization query result, a list of perception terminals authorized by the second network function network element in the first perception terminal set to be queried is obtained, and the authorized perception terminal list is the first perception terminal set to be queried or a subset thereof.

[0089] S304: If the third request does not include the information of the first perception terminal set to be queried, receive a fourth request sent by the first network function network element, where the fourth request includes the second perception terminal set to be queried.

[0090] If the third request does not include any information about the sensing terminal, and the requesting terminal is authenticated, the second network function element feeds back authorization information to the AMF. This authorization information serves as authentication confirmation information for the requesting terminal. If the requesting terminal authentication information is confirmed, the AMF selects an appropriate first network function element based on the sensing service request information and sends the sensing service request (first request) to the first network function element.

[0091] Here, the second perception terminal set to be queried included in the fourth request is a candidate perception terminal set determined by the first network function network element. The control plane function of the first network function network element determines the candidate perception terminal set based on the perception request information, and sends an authorization information query request (fourth request) for the candidate perception terminal set to the second network function network element.

[0092] S305: Based on the fourth request, obtain a list of perception terminals in the second perception terminal set to be queried that are authorized by the second network function network element and meet the perception service request information.

[0093] The second network function network element queries whether the perception terminal in the second perception terminal set supports the perception service and whether it is authorized, determines the list of perception terminals that meet the perception service request information, and the AMF ID that serves the perception terminal list.

[0094] The second network function network element feeds back the authorization information to the first network function network element, namely the list of perception terminals that meet the perception service request information and the AMF ID list that serves the perception terminal list.

[0095] In the embodiment of the present disclosure, the second network function network element receives a third request, which includes perception service request information and information of the requesting terminal. The requesting terminal is authenticated based on the perception service request information and the information of the requesting terminal. If the third request also includes information of the first perception terminal set to be queried, then when the authentication of the requesting terminal is passed, a list of perception terminals in the first perception terminal set to be queried that are authorized by the second network function network element and meet the perception service request information is obtained. If the third request does not include information of the first perception terminal set to be queried, a fourth request sent by the first network function network element is received, and the fourth request includes the second perception terminal set to be queried. Based on the fourth request, a list of perception terminals in the second perception terminal set to be queried that are authorized by the second network function network element and meet the perception service request information is obtained. The embodiment of the present disclosure enhances the function of the second network function network element so that it has both authentication query of the perception request terminal and authorization query of the perception detection terminal, thereby realizing security protection of the perception service from perception request to perception detection and ensuring the privacy of the perception service.

[0096] As shown in FIG4 , FIG4 is a schematic diagram of a process of a perception service provided by an embodiment of the present disclosure, including the following steps:

[0097] Step 1: The UE initiates a perception request to the AMF. The request information includes the service type (such as dynamic map, speed detection, vehicle tracking, emergency notification, vehicle audit), service requirements (perception resolution, perception accuracy, frame rate, duration, Area information, latency, UE information (such as vehicle type, vehicle identification)), etc. If the UE explicitly specifies the perception node information, the perception request will also carry the perception node ID.

[0098] Step 2: AMF initiates a perception service authorization request to UDM. The request information includes the service type and UE information. Note that if the UE does not specify the perception node information, the UE information in this step is the information of the requesting node UE. If the UE specifies the perception node information, the UE information in this step includes the information of the requesting node UE and the information of the perception node UE, and steps 7, 8 and 9 are omitted.

[0099] Step 3: UDM queries the authorization information. If the UE does not specify the perception node information, UDM queries the requesting node UE for identity authentication and authorization. If the UE specifies the perception node information, in addition to querying the requesting node UE for identity authentication and authorization, UDM also queries whether the specified UE (perception node) supports the perception service and whether it is authorized, and determines the perception node UE list that meets the perception service request information (the UE list is the specified perception node UE set or its subset), as well as the AMF ID serving the UE list.

[0100] Step 4: UDM feeds back the authorization information to AMF: If the UE does not specify the perception node information, this authorization information is the authentication confirmation information of the requesting node UE; if the UE specifies the perception node information, this authorization information is the authentication confirmation information of the requesting node UE, as well as the perception node UE list that meets the perception service request information and the AMF ID list that serves the UE list.

[0101] Step 5: AMF selects SF. If the requesting node UE authentication information has been confirmed, AMF selects the appropriate SF based on the perception service request information (if the perception node UE is not specified in the request information) or the AMF ID list returned by UDM (if the perception node UE is specified in the request information).

[0102] First, SF registers its service area to the NRF network element. No perception node is specified. The AMF that receives the perception request will query the NRF and select the SF serving the area by analyzing the target area information of the perception request. After the perception node is specified, the AMF ID of the service perception node UE is obtained by querying the UDM, and then the SF is selected based on the AMF ID (also by querying the NRF to find the SF that matches the area or location information of these AMF IDs).

[0103] Step 6: AMF sends the sensing request to SF.

[0104] It should be understood that the perception requests of step 1 and step 6 are different.

[0105] Step 7: The control plane function of the SF determines the candidate perception node UE set based on the perception request information, and sends an authorization information query request of the perception node UE to the UDM.

[0106] Step 8: UDM performs authorization information query. UDM queries whether the above-mentioned perception node UE supports the perception service and whether it is authorized, and determines the list of perception node UEs that are authorized to meet the perception service request information (the UE list is a specified perception node UE set or a subset thereof), and the AMF ID serving the UE list.

[0107] Step 9: UDM feeds back the authorization result to SF, namely the list of perception node UEs that meet the perception service request information and the list of AMF IDs serving the UE list.

[0108] Note: If the sensing service request message contains the information of the sensing node UE, steps 7, 8 and 9 are omitted.

[0109] Step 10: The SF control plane function sends a perception confirmation request to the UE in the authorized perception node UE list to confirm whether the perception node UE can perform perception detection.

[0110] Step 11: The sensing node UE will confirm whether sensing detection can be performed based on the load or other information, and send a sensing confirmation message to the SF.

[0111] Step 12: The SF control plane function determines the perception control parameters based on the perception request information, including the distance / speed / angle resolution and accuracy of the perception target, frame rate, duration, perception measurement data reporting cycle, update or end process instructions, etc., and sends a perception control request to the perception node UE that has been confirmed to be capable of perception detection.

[0112] Step 13: The sensing node UE performs sensing detection and obtains sensing data;

[0113] Step 14: The sensing node UE reports the sensing data to the SF user plane function;

[0114] Step 15: The SF user plane function performs perception calculation. Considering that the perception node UE actually performing detection may be a subset of the perception node UE set required in the perception request, the SF user plane needs to analyze and calculate these partial data to achieve the perception result required by the perception request.

[0115] Step 16: SF returns the sensing result to AMF.

[0116] Step 17: AMF returns the sensing result to the requesting node UE.

[0117] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present disclosure.
