[0036] Embodiments of the present disclosure provide a privacy verification method, a communication device, and a storage medium during positioning measurement.

[0037] A first aspect provides a privacy verification method during positioning measurement, which is executed by a first network node, and the method includes: receiving a first request sent by a second network node; the first request indicates that the first user equipment UE requests a sideline SL positioning measurement between two second UEs, or the first request indicates that the first UE requests an SL positioning result between at least two second UEs; the first request includes information of the first UE and information of at least one of the at least two second UEs; based on the privacy configuration of the at least two second UEs, verify whether the SL positioning results of the at least two second UEs are allowed to be disclosed; allow the SL positioning results of the at least two second UEs to be disclosed, and send a second request to the second network node; the second request includes information of the first UE and at least two second UEs; the information of the first UE is at least used by the second network node to obtain a verification result of whether the at least two second UEs allow the SL positioning results to be disclosed to the first UE; the SL positioning result is the result of the SL positioning measurement.

[0038] Based on the above scheme, not only will it be verified whether the SL positioning results of at least two second UEs are allowed to be disclosed, but it will also be verified whether the SL positioning results of at least two second UEs are allowed to be disclosed to the first UE, so as to reduce the privacy leakage caused by the disclosure of the SL positioning results of the second UE to a specific UE.

[0039] In some embodiments of the first aspect, the method further includes: not allowing the SL positioning results of the at least two second UEs to be disclosed, and sending a failure response to the first request to the second network node.

[0040] Based on the above scheme, when the SL positioning results of at least two second UEs are not allowed to be disclosed, the first network node will directly send a failure response to the first request, thereby not performing the SL positioning measurement between at least two second UEs, so that the SL positioning results of at least two second UEs will not be exposed to the first UE.

[0041] In some embodiments of the first aspect, the SL positioning results of at least two second UEs are allowed to be disclosed, and a second request is sent to the second network node, including: allowing the SL positioning results of at least two second UEs to be disclosed and allowing the SL positioning results of at least two second UEs to be disclosed to any UE, and sending a second request to the second network node.

[0042] Based on the above solution, the conditions for the first network node to send the second request to the second network node to trigger the acquisition of the verification result are further defined, thereby reducing unnecessary verifications.

[0043] In some embodiments of the first aspect, the method also includes: receiving a response to a second request sent by the second network node, the response to the second request including a verification result; the verification result indicates whether at least two second UEs are allowed to disclose the SL positioning results to the first UE; and sending a response to the first request to the second network node based on whether at least two second UEs are allowed to disclose the SL positioning results to the first UE.

[0044] Based on the above scheme, after the first network node receives the verification result carried in the response to the second request of the second network node, it determines how to send the response to the first request to the second network node according to the verification results of at least two second UEs. In this way, it can ensure that the SL positioning measurement between the at least two second UEs is initiated only when the SL positioning results of the at least two second UEs are allowed to be disclosed to the first UE, otherwise the SL positioning measurement between the at least two second UEs is not performed.

[0097] Figure 1 It is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0098] like Figure 1 As shown, the communication system 100 includes a terminal 101 and a network device 102. The network device 102 may include an access network device and / or a core network device.

[0099] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.

[0100] In some embodiments, the terminal is also referred to as User Equipment (UE).

[0101] In some embodiments, the access network device may be, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.

[0102] In some embodiments, the technical approach of the present disclosure may be applicable to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure may become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces may be implemented through software or programs.

[0103] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0104] In some embodiments, the core network device may be a single device including a first network element, or may be a plurality of devices or a group of devices, each including a first network element. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0105] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical approach of the embodiment of the present disclosure, and does not constitute a limitation on the technical approach provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical approach provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0106] The following embodiments of the present disclosure can be applied to Figure 1 The communication system 100, or a portion thereof, is shown but is not limited thereto. Figure 1 The various entities shown are examples, and the communication system may include Figure 1 All or part of the subject, and may also include Figure 1 For other entities other than the above, the number and form of each entity are arbitrary, and the connection relationship between each entity is an example. The entities may be connected or not connected, and the connection may be in any way, which may be direct or indirect, and may be wired or wireless.

[0107] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems using configuration methods for other resources, and next-generation systems based on and extending these systems. Furthermore, multiple systems may be combined (for example, LTE and NR).

[0108] The designated SL positioning client UE can invoke the SL positioning service executed between the measured UEs. In order to access the SL positioning service and obtain the SL positioning results of other UEs, the client UE needs to be authorized to avoid infringing the privacy of the measured UE.

[0109] Authorization of the client UE is not only for service access, but also for protecting the UE privacy. This is because even if the client UE is authorized to request the SL positioning service, it does not mean that the SL positioning results of the UE under test can be disclosed to any client UE. For example, the client UE may be allowed to request the SL positioning results between UE1 and UE2, but not allowed to request the SL positioning results between UE3 and UE4. If the privacy protection of the UE under test is not further verified, there is still a risk of exposing the SL positioning results between specific UEs to unauthorized client UEs. Therefore, whether the client UE is allowed to obtain the SL positioning results of the UE under test requires further authorization.

[0110] The client UE requests authorization for the SL positioning service through the network. For example, the client UE can request the GMLC to perform authorization to verify whether the positioning service can be exposed (i.e., disclosed), and the GMLC checks the UE privacy profile of the UE under test. However, the UE privacy profile only contains a general indication of whether disclosure to the SL positioning client UE is allowed, and does not contain information about any specific client UE. This means that the UE to be measured can only make a decision between allowing or not allowing disclosure to the SL positioning client UE, without knowing which specific client UE is requesting the service. Therefore, it is necessary to study a method that enables the UE to be measured to handle privacy control by obtaining information about the specific client UE requesting the service and authenticating the client UE.

[0111] In view of this, embodiments of the present disclosure provide a method for enabling a UE under test to handle privacy control by understanding a specific client UE requesting a service.

[0112] The reference point NL6 between User Data Management (UDM) and GMLC is used to transmit the UE privacy profile to GMLC to authorize the exposure of ranging / SL positioning services. Therefore, when the SL positioning client UE requests the SL positioning result of the measured UE, it is necessary to trigger GMLC to retrieve the UE privacy profile from UDM to determine whether to trigger privacy verification. The privacy verification may include but is not limited to judging based on whether the received request contains the client UE information of SL positioning. If the received request contains the client UE information of SL positioning, it means that the UE privacy of exposing the SL positioning result to the client UE needs to be verified. Two optional embodiments are provided below to perform privacy verification for exposing the SL positioning result to the client UE.

[0113] like Figure 2A As shown, the embodiment of the present disclosure provides a privacy verification method during positioning measurement, which is performed by a communication system. The method may include:

[0114] S2101: The first UE or the second UE sends a third request to the second network node.

[0115] In some embodiments, the first UE is a client UE. The client UE may be a UE that requests, uses, or consumes SL positioning results. The second UE may be a UE that participates in SL positioning services to obtain SL positioning results. In some embodiments, the second UE may be a measured UE or a UE participating in positioning measurements.

[0116] In some embodiments, the third request may indicate that the first UE requests the SL positioning results of at least two second UEs. The SL positioning result may be a positioning result obtained based on SL measurement. For example, the SL positioning result may be a relative positioning result between the two second UEs.

[0117] In some embodiments, the SL positioning results of the at least two second UEs may include but are not limited to at least one of the following:

[0118] Positioning information (e.g., absolute position coordinates and / or relative position information relative to a reference point) of one or more second UEs of the at least two second UEs;

[0119] a relative positional relationship between any two second UEs of the at least two second UEs;

[0120] Whether the relative position relationship between any two second UEs among the at least two second UEs satisfies a specified condition. For example, the specified condition may include but is not limited to the distance between any two second UEs among the at least two second UEs being less than or equal to a distance threshold.

[0121] In some embodiments, the third request indicates that the first user equipment UE requests sidelink (SL) positioning measurements between two second UEs.

[0122] In some embodiments, the third request may include but is not limited to various non-access stratum (NAS) messages.

[0123] In some embodiments, the third request may include but is not limited to a SL positioning service request message.

[0124] In some embodiments, the information of the first UE is at least used by the second network node to obtain a verification result of whether at least two second UEs are allowed to disclose the SL positioning result to the first UE; the SL positioning result is the result of the SL positioning measurement.

[0125] In some embodiments, the third request may include, but is not limited to, information about the first UE and information about the second UE. For example, the information about the first UE may include, but is not limited to, identification information of the first UE. For example, the identification information of the first UE may include, but is not limited to, a user information identifier (User Info ID) and / or a subscription permanent identifier (SUPI).

[0126] In some embodiments, the third request may include information of at least one second UE among at least two second UEs. For example, the third request may include information of each second UE among at least two second UEs, so that the information of each second UE is given to the network side, which facilitates privacy verification on the network side. For example, the third request may include information of the second UE under test among at least two second UEs. The second UE under test is a UE that needs to expose its location information. Only the information of the second UE under test is given to the network side, and the network side only needs to verify whether the SL positioning result of the second UE under test is open to the first UE. In some embodiments, the third request may only carry information of the second UE of a specific security level among the second UEs, so that the network side only needs to verify whether the SL positioning result of the UE of a specific security level is open to the first UE, and the SL positioning result of the UE with a low security level can be open to any client UE by default.

[0127] It is worth noting that the third request sent by the first UE may also include information about the second UE; similarly, the third request sent by the second UE may include information about the first UE. This disclosure does not limit how the first UE obtains information about the second UE, nor does it limit how the second UE obtains information about the first UE.

[0128] S2102: The second network node sends a first request to the first network node.

[0129] In some embodiments, the first request includes information of the first UE and information of at least one of the at least two second UEs.

[0130] In some embodiments, the second network node may be a core network node. Exemplarily, the second network node may include, but is not limited to, an Access Management Function (AMF). Exemplarily, if the third request originates from a first UE, the second network node may be the serving AMF for the first UE. If the third request originates from a second UE, the second network node may be the serving AMF for the second UE.

[0131] In some embodiments, the second network node sends the first request to the first network node according to the third request. For example, after receiving the third request, the second network node sends the first request to the first network node.

[0132] In some embodiments, the first network node may also be a core network node. Exemplarily, the first network node may include but is not limited to: a Gateway Mobile Location Center (GMLC).

[0133] In some embodiments, the first request may include, but is not limited to, Ngml_Location_ProvideRangingRequest.

[0134] In some embodiments, the first request includes information of the first UE carried in the third request and information of at least one of the at least two second UEs. For example, the first request includes information of the first UE carried in the third request and information of at least one of the second UEs.

[0135] The information carried in the first request can refer to the information carried in the third request.

[0136] In some embodiments, the first request indicates that the first user equipment UE requests sidelink (SL) positioning measurements between at least two second UEs.

[0137] In some other embodiments, the first request indicates that the first UE requests the SL positioning result between at least two second UEs.

[0138] In some embodiments, when the second network node receives information about only one second UE, it may select another second UE. How the second network node determines the other second UE based on the information about the one second UE is not limited herein.

[0139] S2103a: The first network node sends a second request to the second network node.

[0140] In some embodiments, the first network node verifies whether the SL positioning results of at least two second UEs are allowed to be disclosed based on the privacy configuration of the second UEs. Exemplarily, the first network node determines whether the SL positioning results of each of the at least two second UEs are allowed to be disclosed based on the privacy configuration of each second UE.

[0141] In some embodiments, the privacy configuration may also be referred to as a privacy profile. In some embodiments, the first network node may request the privacy configuration of the second UE from a third network node. Exemplarily, the third network node includes but is not limited to a User Data Management (UDM). Exemplarily, the privacy configuration is generated based on the second UE's subscription information.

[0142] In some embodiments, the privacy configuration of the second UE may be pre-configured locally at the first network node. In this case, the first network node does not need to request the privacy configuration of the second UE from the third network node.

[0143] In some embodiments, the privacy configuration may be used to determine at least one of the following:

[0144] Whether to allow disclosure of the SL positioning result related to the second UE;

[0145] Whether to allow disclosure of the SL positioning result related to the second UE to the UE;

[0146] Whether to allow disclosure of the SL positioning results related to the second UE to any UE;

[0147] Whether to allow the SL positioning results related to the second UE to be disclosed to the server.

[0148] In some embodiments, if the privacy configuration indicates that the SL positioning results related to the second UE are allowed to be disclosed, or the SL positioning results related to the second UE are allowed to be disclosed to the UE, or the SL positioning results related to the second UE are allowed to be disclosed to the server, then it can be considered that the SL positioning results of the second UE are allowed to be disclosed but the SL positioning results related to the second UE are not allowed to be disclosed to any UE.

[0149] In some embodiments, if the privacy configuration indicates that the SL positioning results related to the second UE are allowed to be disclosed to any UE, it can be considered that the second UE allows the SL positioning results and allows the SL positioning results related to the second UE to be disclosed to any UE.

[0150] In some embodiments, when the SL positioning results of each of the at least two second UEs are allowed to be disclosed, the first network node sends a second request to the second network node.

[0151] In some embodiments, when the SL positioning results of each of the at least two second UEs are allowed to be disclosed but are not allowed to be disclosed to any client UE, the first network node sends a second request to the second network node.

[0152] In some embodiments, the second request includes information of the first UE and at least two second UEs.

[0153] In some embodiments, the information of the first UE is at least used by the second network node to obtain whether at least two second UEs are allowed to disclose the SL positioning result to the first UE.

[0154] In some embodiments, the first network node sends a second request to the second network nodes of at least two second UEs. For example, if the at least two second UEs have the same second network node, the first network node may simply send a single second request to the second network node. If the at least two second UEs have different second network nodes, the first network node needs to send a second request to the second network node of each second UE separately.

[0155] In some embodiments, the step of determining whether the SL positioning results of at least two second UEs are allowed to be disclosed based on the privacy configuration of the second UE is an optional step. For example, the first network node may determine to directly proceed to the verification step of whether the SL positioning results of at least two second UEs are disclosed to the first UE. Exemplarily, perhaps the SL positioning results of at least two second UEs are not set with a privacy configuration, and it is known that the first UE may be a specific UE. The step of whether the SL positioning results of at least two second UEs are allowed to be disclosed can be skipped, and the step of determining whether the SL positioning results of at least two second UEs are allowed to be disclosed to the first UE can be directly entered.

[0156] S2103b: The first network node sends a failure response or a success response to the first request to the second network node.

[0157] In some embodiments, according to the privacy configuration of the second UE not allowing the SL positioning results of at least two second UEs to be disclosed, the first network node sends a failure response to the first request to the second network node.

[0158] In some embodiments, the failure response to the first request may indicate a rejection of the SL positioning measurement corresponding to the first request. In some embodiments, the failure response to the first request may further include a failure reason. For example, the failure reason may indicate that the privacy configuration indicates that the SL positioning result is not allowed to be disclosed.

[0159] In some embodiments, if the privacy configuration of the second UE indicates that the SL positioning result is allowed to be disclosed to any UE, the first network node sends a successful response to the first request to the second network node. The successful response to the first request may indicate that the SL positioning measurement of the first request is accepted. If the privacy configuration of the second UE indicates that the SL positioning result is allowed to be disclosed to any UE, it is equivalent to indicating that the privacy configuration of the second UE can independently determine that the second UE allows the SL positioning result to be disclosed to the first UE. Therefore, the first network node does not need to trigger the second network node again to initiate authentication of whether the first UE is allowed to obtain the SL positioning result of the second UE.

[0160] S2104: The second network node sends a fourth request to at least one UE among the at least two second UEs.

[0161] In some embodiments, the fourth request includes at least information of the first UE.

[0162] In some embodiments, the second network node sends a fourth request to the second UE based on the second request sent by the first network node. Exemplarily, the second network node sends the fourth request including the information of the first UE to the corresponding second UE based on the second request including the information of the second UE.

[0163] In some embodiments, the fourth request is used to request the second UE to verify whether it is allowed to disclose the SL positioning result to the first UE.

[0164] In some embodiments, the fourth request may include, but is not limited to, NAS_Location_Notification_invokeRequest.

[0165] S2105: The second UE sends the verification result to the second network node.

[0166] In some embodiments, the second UE sends a verification result to the second network node according to the fourth request.

[0167] In some embodiments, after receiving the fourth request, the second UE displays the information of the first UE on a user interface (UI) and obtains a verification result based on a user operation on the information of the first UE.

[0168] In some embodiments, after receiving the fourth request, the second UE may obtain a verification result according to a device setting of the second UE.

[0169] In some embodiments, the second UE may return the verification result to the second network node by carrying it in a response to the fourth request. Exemplarily, the verification result may be carried in a NAS_Location_Notification_invoke Response.

[0170] S2106: The second network node determines whether to disclose the SL positioning result to the first UE according to the verification result of at least one second UE of the at least two second UEs.

[0171] In some embodiments, S2106 may include:

[0172] The second network node determines whether to disclose the SL positioning result to the first UE based on the verification result of the UE under test among the at least two second UEs. For example, the at least two second UEs include a reference UE and a UE under test. The location information of the reference UE may be known, and the location information of the UE under test is positional. At this time, the location information of the UE under test can be obtained by measuring the relative position between the UEs under test through the reference UE. At this time, it can be determined whether to disclose the SL positioning result to the first UE based solely on the verification result of the UE under test. In this case, if the verification result of the UE under test indicates that it is willing to disclose the SL positioning result to the first UE, it can be determined to disclose the SL positioning result between the at least two second UEs to the first UE.

[0173] In some embodiments, S2106 may include: the second network node may determine whether to disclose the SL positioning result to the first UE based on a verification result of the second UE among at least two second UEs whose privacy configuration does not specify that the SL positioning result can be disclosed to any UE. In this case, if the verification result of the second UE whose privacy configuration does not specify that the SL positioning result can be disclosed to any UE indicates a willingness to disclose the SL positioning result to the first UE, it may be determined to disclose the SL positioning result between the at least two second UEs to the first UE.

[0174] In some embodiments, the second network node determines whether to disclose the SL positioning result to the first UE based on the verification results of each of the at least two second UEs. In this case, after receiving the verification results of each second UE, the second network node determines whether each second UE allows its own SL positioning result to be disclosed to the first UE. Exemplarily, if each second UE allows the SL positioning result to be disclosed to the first UE, it is determined that the SL positioning results of the at least two second UEs are agreed to be disclosed to the first UE. Also exemplarily, if at least one second UE does not agree to disclose the SL positioning result to the first UE, it is determined that the SL positioning results of the at least two second UEs are not agreed to be disclosed to the first UE.

[0175] S2107: The second network node sends a response to the second request to the first network node.

[0176] In some embodiments, the response to the second request indicates whether the SL positioning results of at least two second UEs are allowed to be opened to the first UE.

[0177] In some embodiments, the response to the second request is a successful response to the first request or a failed response to the second request.

[0178] In some embodiments, a successful response to the second request indicates that at least two second UEs allow (or agree) to disclose the SL positioning result to the first UE.

[0179] In some embodiments, the failed response to the second request indicates that at least two second UEs do not allow (ie, do not agree) to disclose the SL positioning result to the first UE.

[0180] In some embodiments, the failure response to the second request will carry a failure reason. The failure reason may indicate the reason for not agreeing to disclose the SL positioning results of at least two second UEs to the first UE. For example, the failure reason may include but is not limited to one or more second UEs not agreeing to disclose the SL positioning results to the first UE.

[0181] In some embodiments, in the embodiments of the present disclosure, the second network node determines whether to finally allow the SL positioning results of at least two second UEs to be disclosed to the first UE based on the verification results of each second UE. In this way, when the first network node receives a response to the first request, it can know whether it is necessary to trigger the SL positioning measurement between at least two second UEs.

[0182] S2108: The second network node initiates SL positioning measurement between at least two second UEs.

[0183] It is worth noting that: in some cases, the disclosed embodiments of this application do not focus on the specific execution of S2108. In some cases, S2108 may be an optional step. For example, if the current network side has obtained the SL positioning result between at least two second UEs before receiving the current third request or during the process of receiving the third request, then after completing the above S2107, S2108 may not be executed to trigger the SL positioning measurement between the at least two second UEs.

[0184] In some embodiments, if the second network node determines, based on the verification results and / or privacy configuration of each of the at least two second UEs, that the SL positioning result is permitted to be disclosed to the first UE, the second network node may directly initiate SL positioning measurements between the two second UEs. Exemplarily, the second network node sends a response to the second request to the first network node.

[0185] It is worth noting that: when the second network node determines to disclose the SL positioning results of at least two second UEs to the first UE based on the verification results provided by the second UE, it can initiate SL positioning measurements between at least two second UEs without receiving a response to the first request.

[0186] like Figure 2B As shown, the embodiment of the present disclosure provides a privacy verification method during positioning measurement, which is performed by a communication system. The method may include:

[0187] S2201: The first UE or the second UE sends a third request to the second network node.

[0188] In some embodiments, the first UE is a client UE. The client UE may be a UE that requests, uses, or consumes the SL positioning result. The second UE may be a UE that participates in the SL positioning service to obtain the SL positioning result. For example, the third request may indicate that the first UE requests the SL positioning results of at least two second UEs. The SL positioning result may be a relative positioning result between the two second UEs.

[0189] In some embodiments, the SL positioning results of the at least two second UEs may include but are not limited to at least one of the following:

[0190] Positioning information (e.g., absolute position coordinates and / or relative position information relative to a reference point) of one or more second UEs of the at least two second UEs;

[0191] a relative positional relationship between any two second UEs of the at least two second UEs;

[0192] Whether the relative position relationship between any two second UEs among the at least two second UEs satisfies a specified condition. For example, the specified condition may include but is not limited to the distance between any two second UEs among the at least two second UEs being less than or equal to a distance threshold.

[0193] In some embodiments, the third request indicates that the first user equipment UE requests sidelink (SL) positioning measurements between two second UEs.

[0194] In some embodiments, the third request may include but is not limited to various non-access stratum (NAS) messages.

[0195] In some embodiments, the third request may include but is not limited to a SL positioning service request message.

[0196] In some embodiments, the third request may include, but is not limited to, information about the first UE and information about the second UE. For example, the information about the first UE may include, but is not limited to, identification information of the first UE. For example, the identification information of the first UE may include, but is not limited to, a user information identifier (User Info ID) and / or a subscription permanent identifier (SUPI).

[0197] In some embodiments, the third request may include information of at least one second UE among at least two second UEs. For example, the third request may include information of each second UE among at least two second UEs, so that the information of each second UE is given to the network side, which facilitates privacy verification on the network side. For example, the third request may include information of the second UE under test among at least two second UEs. The second UE under test is a UE that needs to expose its location information. Only the information of the second UE under test is given to the network side, and the network side only needs to verify whether the SL positioning result of the second UE under test is open to the first UE. In some embodiments, the third request may only carry information of the second UE of a specific security level among the second UEs, so that the network side only needs to verify whether the SL positioning result of the UE of a specific security level is open to the first UE, and the SL positioning result of the UE with a low security level can be open to any client UE by default.

[0198] It is worth noting that the third request sent by the first UE may also include information about the second UE; similarly, the third request sent by the second UE may include information about the first UE. This disclosure does not limit how the first UE obtains information about the second UE, nor does it limit how the second UE obtains information about the first UE.

[0199] S2202: The second network node sends a first request to the first network node.

[0200] In some embodiments, the first request includes information of the first UE and information of at least one of the at least two second UEs.

[0201] In some embodiments, the first request includes information of the first UE carried in the third request and information of at least one of the at least two second UEs. For example, the first request includes information of the first UE carried in the third request and information of at least one of the second UEs.

[0202] The information carried in the first request can refer to the information carried in the third request.

[0203] In some embodiments, the first request indicates that the first user equipment UE requests sidelink (SL) positioning measurements between at least two second UEs.

[0204] In some other embodiments, the first request indicates that the first UE requests the SL positioning result between at least two second UEs.

[0205] In some embodiments, the second network node may be a core network node. Exemplarily, the second network node may include, but is not limited to, an Access Management Function (AMF). Exemplarily, if the third request originates from a first UE, the second network node may be the serving AMF for the first UE. If the third request originates from a second UE, the second network node may be the serving AMF for the second UE.

[0206] In some embodiments, the second network node sends the first request to the first network node according to the third request. For example, after receiving the third request, the second network node sends the first request according to the first network node.

[0207] In some embodiments, the first network node may also be a core network node. Exemplarily, the first network node may include but is not limited to: a Gateway Mobile Location Center (GMLC).

[0208] In some embodiments, the first request may include, but is not limited to, Ngml_Location_ProvideRangingRequest.

[0209] In some embodiments, the first request includes information of the first UE and information of each of the at least two second UEs carried in the third request.

[0210] S2203: The first network node sends a second request to the second network node.

[0211] In some embodiments, the first network node verifies whether the SL positioning results of at least two second UEs are allowed to be disclosed based on the privacy configuration of the second UEs. Exemplarily, the first network node determines whether the SL positioning results of each of the at least two second UEs are allowed to be disclosed based on the privacy configuration of each second UE.

[0212] In some embodiments, the privacy configuration may also be referred to as a privacy profile. In some embodiments, the first network node may request the privacy configuration of the second UE from a third network node. Exemplarily, the third network node includes but is not limited to a User Data Management (UDM). Exemplarily, the privacy configuration is generated based on the second UE's subscription information.

[0213] In some embodiments, the privacy configuration of the second UE may be pre-configured locally at the first network node. In this case, the first network node does not need to request the privacy configuration of the second UE from the third network node.

[0214] In some embodiments, the privacy configuration may be used to determine at least one of the following:

[0215] Whether to allow disclosure of the SL positioning result related to the second UE;

[0216] Whether to allow disclosure of the SL positioning result related to the second UE to the UE;

[0217] Whether to allow disclosure of the SL positioning results related to the second UE to any UE;

[0218] Whether to allow the SL positioning results related to the second UE to be disclosed to the server.

[0219] In some embodiments, if the privacy configuration indicates that the SL positioning results related to the second UE are allowed to be disclosed, or the SL positioning results related to the second UE are allowed to be disclosed to the UE, or the SL positioning results related to the second UE are allowed to be disclosed to the server, then it can be considered that the SL positioning results of the second UE are allowed to be disclosed but the SL positioning results related to the second UE are not allowed to be disclosed to any UE.

[0220] In some embodiments, if the privacy configuration indicates that the SL positioning results related to the second UE are allowed to be disclosed to any UE, it can be considered that the second UE allows the SL positioning results and allows the SL positioning results related to the second UE to be disclosed to any UE.

[0221] In some embodiments, when the SL positioning results of each of the at least two second UEs are allowed to be disclosed, the first network node sends a second request to the second network node.

[0222] In some embodiments, when the SL positioning results of each of the at least two second UEs are allowed to be disclosed but are not allowed to be disclosed to any client UE, the first network node sends a second request to the second network node.

[0223] In some embodiments, the second request includes information of the first UE and at least two second UEs.

[0224] In some embodiments, the information of the first UE is at least used by the second network node to obtain whether at least two second UEs are allowed to disclose the SL positioning result to the first UE.

[0225] In some embodiments, the SL positioning result is the result of a SL positioning measurement.

[0226] In some embodiments, the first network node sends a second request to the second network nodes of at least two second UEs. For example, if the at least two second UEs have the same second network node, the first network node may simply send a single second request to the second network node. If the at least two second UEs have different second network nodes, the first network node needs to send a second request to the second network node of each second UE separately.

[0227] S2204: The second network node sends a fourth request to at least one UE among the at least two second UEs.

[0228] In some embodiments, the fourth request includes at least information of the first UE.

[0229] In some embodiments, the second network node sends a fourth request to the second UE based on the second request sent by the first network node. Exemplarily, the second network node sends the fourth request including the information of the first UE to the corresponding second UE based on the second request including the information of the second UE.

[0230] In some embodiments, the fourth request is used to request the second UE to verify whether it is allowed to disclose the SL positioning result to the first UE.

[0231] In some embodiments, the fourth request may include, but is not limited to, NAS_Location_Notification_invokeRequest.

[0232] S2205: The second UE sends the verification result to the second network node.

[0233] In some embodiments, the second UE sends a verification result to the second network node according to the fourth request.

[0234] In some embodiments, after receiving the fourth request, the second UE displays the information of the first UE on a user interface (UI) and obtains a verification result based on a user operation on the information of the first UE.

[0235] In some embodiments, after receiving the fourth request, the second UE may obtain a verification result according to a device setting of the second UE.

[0236] In some embodiments, the second UE may return the verification result to the second network node by carrying it in a response to the fourth request. Exemplarily, the verification result may be carried in a NAS_Location_Notification_invoke Response.

[0237] S2206: The second network node sends a response to the second request to the first network node.

[0238] In some embodiments, the response to the second request includes a verification result provided by at least one second UE, where the verification result indicates whether the corresponding second UE allows the SL positioning result to be disclosed to the first UE.

[0239] In some embodiments, the response to the second request may include a verification result provided by each of the at least two second UEs.

[0240] S2207: The first network node determines whether to disclose the SL positioning result to the first UE according to the verification result of at least one second UE of the at least two second UEs.

[0241] In some embodiments, the first network node determines whether to disclose the SL positioning result to the first UE based on the verification result of each of the at least two second UEs.

[0242] In some embodiments, the first network node determines whether to disclose the SL positioning result to the first UE based on verification results of the second UEs of specific security levels of at least two second UEs.

[0243] In some embodiments, the first network node determines whether to disclose the SL positioning result to the first UE based on the verification results of the measured second UEs of at least two second UEs.

[0244] In some embodiments, after the first network node receives the response to the second request provided by the second network node, it determines whether to disclose the SL positioning results of at least two second UEs to the first UE based on the verification results of each second UE carried in the response to the second request.

[0245] In some embodiments, after receiving the verification results of each second UE, the first network node determines whether each second UE allows its own SL positioning results to be disclosed to the first UE. Exemplarily, if each second UE allows the SL positioning results to be disclosed to the first UE, it is determined that the SL positioning results of the at least two second UEs are agreed to be disclosed to the first UE. Exemplarily, if at least one second UE does not agree to disclose the SL positioning results to the first UE, it is determined that the SL positioning results of the at least two second UEs are not agreed to be disclosed to the first UE.

[0246] S2208: The first network node sends a response to the first request to the second network node.

[0247] In some embodiments, the response to the first request includes: a successful response to the first request and / or a failed response to the first request.

[0248] In some embodiments, according to the privacy configuration of the second UE not allowing the SL positioning results of at least two second UEs to be disclosed, the first network node sends a failure response to the first request to the second network node.

[0249] In some embodiments, a successful response to the first request indicates a determination to perform the SL positioning measurement corresponding to the first request.

[0250] In some embodiments, the failure response to the first request may indicate a determination not to perform (i.e., reject) the SL positioning measurement corresponding to the first request. In some embodiments, the failure response to the first request may also include a failure reason. For example, the failure reason may indicate that the privacy configuration indicates that the SL positioning result is not allowed to be disclosed.

[0251] In some embodiments, if the privacy configuration of the second UE indicates that the SL positioning result is allowed to be disclosed to any UE, the first network node sends a successful response to the first request to the second network node. The successful response to the first request may indicate that the SL positioning measurement of the first request is accepted. If the privacy configuration of the second UE indicates that the SL positioning result is allowed to be disclosed to any UE, it is equivalent to indicating that the privacy configuration of the second UE can independently determine that the second UE allows the SL positioning result to be disclosed to the first UE. Therefore, the first network node does not need to trigger the second network node again to initiate authentication of whether the first UE is allowed to obtain the SL positioning result of the second UE.

[0252] In some embodiments, the first network node sends a response to the first request to the second network node based on the verification results of each second UE.

[0253] In some embodiments, if the privacy configuration indication of the second UE allows disclosure of the SL positioning result of the second UE but does not allow disclosure of the SL positioning result to any UE, how to send a response to the first request to the second network node is determined based on the verification results of each second UE.

[0254] In some embodiments, if each of the at least two second UEs allows disclosure of the SL positioning result to the first UE, a success response to the first request is sent to the second network node; otherwise, a failure response to the first request is sent to the second network node.

[0255] S2209: The second network node initiates SL positioning measurement between at least two second UEs.

[0256] In some embodiments, the second network node initiates SL positioning measurements between at least two second UEs according to a successful response to the first request.

[0257] In some embodiments, the second network node sends a rejection response of the first request to the first UE or the second UE according to the failure response of the first request. The rejection response indicates that the second network node determines not to perform SL positioning measurement between at least two second UEs.

[0258] It is worth noting that: in some cases, the disclosed embodiments of this application do not focus on the specific execution of S2209. In some cases, S2209 is an optional step. For example, if the current network side has obtained the SL positioning result between at least two second UEs before receiving the current third request or during the process of receiving the third request, then after completing the above S2208, S2209 may not be executed to trigger the SL positioning measurement between the at least two second UEs.

[0259] like Figure 2C As shown, the embodiment of the present disclosure provides a privacy verification method during positioning measurement, which is performed by a communication system. The method may include:

[0260] S2301: The first UE or the second UE sends a third request to the network node.

[0261] The third network node may be any network node, for example, the third network node may be a core network node. Exemplarily, the core network node may include but is not limited to AMF, GMLC or LMF.

[0262] It is worth noting that the description of the third request can be found in Figures 2A to 2B Related description of the corresponding embodiment.

[0265] S2303: The second UE sends a verification result to the network node.

[0266] The relevant description of the verification results here can be found in Figures 2A to 2B The corresponding embodiment of the relevant description. The verification result can be sent to 2A to Figure 2B This corresponds to the description of the UE sending the verification result in the embodiment.

[0267] S2304: Determine whether to disclose the SL positioning result to the first UE based on the verification result of at least one second UE among the at least two second UEs.

[0268] It is worth noting that: S2304 determines whether to disclose the SL positioning result to the first UE, see Figure 2A Corresponding embodiment S2106 and / or Figure 2B S2207 of the corresponding embodiment.

[0269] like Figure 3AAs shown, an embodiment of the present disclosure provides a privacy verification method during positioning measurement, wherein the method is performed by a first network node and includes:

[0282] In some embodiments, the optional implementation of S3103 can refer to any optional implementation of S2103b.

[0283] It is worth noting that sending the response to the first request is postponed while sending the second request.

[0284] S3104: Receive a response to the second request.

[0285] In some embodiments, the response to the second request is a successful response to the first request or a failed response to the second request.

[0286] In some embodiments, a successful response to the second request indicates that at least two second UEs agree to disclose the SL positioning result to the first UE.

[0287] In some embodiments, a failed response to the second request indicates that at least two second UEs do not agree to disclose the SL positioning result to the first UE.

[0288] In some embodiments, the failure response to the second request will carry a failure reason. The failure reason may indicate the reason for not agreeing to disclose the SL positioning results of at least two second UEs to the first UE. For example, the failure reason may include but is not limited to one or more second UEs not agreeing to disclose the SL positioning results to the first UE.

[0289] In some embodiments, in the embodiments of the present disclosure, the second network node determines whether to finally allow the SL positioning results of at least two second UEs to be disclosed to the first UE based on the verification results of each second UE. In this way, when the first network node receives a response to the first request, it can know whether it is necessary to trigger the SL positioning measurement between at least two second UEs.

[0290] It is worth noting that, in some embodiments, after receiving the response to the second request, the first network node sends a response to the first request according to the response to the second request.

[0291] like Figure 3B As shown, an embodiment of the present disclosure provides a privacy verification method during positioning measurement, wherein the method is performed by a first network node and includes:

[0292] S3201: Receive the first request.

[0293] In some embodiments, a first request sent by a second network node is received.

[0294] In some embodiments, the first request indicates that the first user equipment UE requests sidelink (SL) positioning measurements between two second UEs.

[0295] In some embodiments, the third request indicates that the first UE requests a SL positioning result between at least two second UEs.

[0296] In some embodiments, the first request includes information of the first UE and information of at least one of the at least two second UEs.

[0297] It is worth noting that the description of the first request can be found in Figure 2B Related description of the corresponding embodiment.

[0298] S3202: Based on the privacy configurations of at least two second UEs, verify whether the SL positioning results of at least two second UEs are allowed to be disclosed.

[0299] In some embodiments, the optional implementation of S3202 can refer to the relevant description based on privacy configuration in S2203.

[0300] S3203: Send a second request.

[0301] In some embodiments, the first network node sends a second request to the second network node.

[0302] In some embodiments, the optional implementation of S3203 can refer to any optional implementation of S2203.

[0303] S3203: Receive a response to the second request.

[0304] In some embodiments, the response to the second request includes a verification result provided by at least one second UE, where the verification result indicates whether the corresponding second UE allows the SL positioning result to be disclosed to the first UE.

[0305] In some embodiments, the response to the second request may include a verification result provided by each of the at least two second UEs.

[0306] In some embodiments, the optional implementation of S3103 can refer to any optional implementation of S2103b.

[0307] S3204: Determine whether to allow the SL positioning results of at least two second UEs to be opened to the first UE based on the verification results provided by each of the at least two second UEs.

[0308] In some embodiments, after the first network node receives the response to the second request provided by the second network node, it determines whether to disclose the SL positioning results of at least two second UEs to the first UE based on the verification results of each second UE carried in the response to the second request.

[0309] In some embodiments, after receiving the verification results of each second UE, the first network node determines whether each second UE allows its own SL positioning results to be disclosed to the first UE. Exemplarily, if each second UE allows the SL positioning results to be disclosed to the first UE, it is determined that the SL positioning results of the at least two second UEs are agreed to be disclosed to the first UE. Exemplarily, if at least one second UE does not agree to disclose the SL positioning results to the first UE, it is determined that the SL positioning results of the at least two second UEs are not agreed to be disclosed to the first UE.

[0310] S3205: Send a response to the first request.

[0311] In some embodiments, the response to the first request includes: a successful response to the first request and / or a failed response to the first request.

[0312] In some embodiments, according to the privacy configuration of the second UE not allowing the SL positioning results of at least two second UEs to be disclosed, the first network node sends a failure response to the first request to the second network node.

[0313] In some embodiments, the failure response to the first request may indicate a determination not to perform (i.e., reject) the SL positioning measurement corresponding to the first request. In some embodiments, the failure response to the first request may also include a failure reason. For example, the failure reason may indicate that the privacy configuration indicates that the SL positioning result is not allowed to be disclosed.

[0314] In some embodiments, if the privacy configuration of the second UE indicates that the SL positioning result is allowed to be disclosed to any UE, the first network node sends a successful response to the first request to the second network node. The successful response to the first request may indicate that the SL positioning measurement of the first request is accepted. If the privacy configuration of the second UE indicates that the SL positioning result is allowed to be disclosed to any UE, it is equivalent to indicating that the privacy configuration of the second UE can independently determine that the second UE allows the SL positioning result to be disclosed to the first UE. Therefore, the first network node does not need to trigger the second network node again to initiate authentication of whether the first UE is allowed to obtain the SL positioning result of the second UE.

[0315] In some embodiments, the first network node sends a response to the first request to the second network node based on the verification results of each second UE.

[0316] In some embodiments, if the privacy configuration indication of the second UE allows disclosure of the SL positioning result of the second UE but does not allow disclosure of the SL positioning result to any UE, how to send a response to the first request to the second network node is determined based on the verification results of each second UE.

[0317] In some embodiments, if each of the at least two second UEs allows disclosure of the SL positioning result to the first UE, a success response to the first request is sent to the second network node; otherwise, a failure response to the first request is sent to the second network node.

[0318] like Figure 4A As shown, an embodiment of the present disclosure provides a privacy verification method during positioning measurement, wherein the method is performed by a second network node. The method may include:

[0319] S4101: Receive the third request.

[0320] In some embodiments, the second network node receives the third request sent by the first UE, or the second network node receives the third request sent by the second UE.

[0321] In some embodiments, the first UE is a client UE. The client UE may be a UE that requests, uses, or consumes the SL positioning result. The second UE may be a UE that participates in the SL positioning service to obtain the SL positioning result. For example, the third request may indicate that the first UE requests the SL positioning results of at least two second UEs. The SL positioning result may be a relative positioning result between the two second UEs.

[0322] In some embodiments, the third request indicates that the first user equipment UE requests sidelink (SL) positioning measurements between two second UEs.

[0323] In some embodiments, the third request may include but is not limited to various non-access stratum (NAS) messages.

[0324] In some embodiments, the third request may include but is not limited to a SL positioning service request message.

[0325] In some embodiments, the information of the first UE is at least used by the second network node to obtain a verification result of whether at least two second UEs are allowed to disclose the SL positioning result to the first UE; the SL positioning result is the result of the SL positioning measurement.

[0326] In some embodiments, the third request may include, but is not limited to, information about the first UE and information about the second UE. For example, the information about the first UE may include, but is not limited to, identification information of the first UE. For example, the identification information of the first UE may include, but is not limited to, a user information identifier (User Info ID) and / or a subscription permanent identifier (SUPI).

[0327] S4102: Send the first request.

[0328] In some embodiments, the second network node sends the first request to the first network node.

[0329] In some embodiments, the first request includes information of the first UE and information of at least one of the at least two second UEs.

[0330] In some embodiments, the second network node may be a core network node. Exemplarily, the second network node may include, but is not limited to, an Access Management Function (AMF). Exemplarily, if the third request originates from a first UE, the second network node may be the serving AMF for the first UE. If the third request originates from a second UE, the second network node may be the serving AMF for the second UE.

[0331] In some embodiments, the second network node sends the first request to the first network node according to the third request. For example, after receiving the third request, the second network node sends the first request according to the first network node.

[0332] In some embodiments, the first network node may also be a core network node. Exemplarily, the first network node may include but is not limited to: a Gateway Mobile Location Center (GMLC).

[0333] In some embodiments, the first request may include, but is not limited to, Ngml_Location_ProvideRangingRequest.

[0334] In some embodiments, the first request includes information of the first UE and information of each of the at least two second UEs carried in the third request.

[0335] In some embodiments, the optional implementation of S4102 can be found in Figure 2A S2102 of the corresponding embodiment.

[0336] S4103a: Receive the second request.

[0337] In some embodiments, the second network node receives the second request sent by the first network node.

[0338] In some embodiments, the second request includes information of the first UE and information of at least two second UEs.

[0339] In some embodiments, the second request is a second request sent when the first network node determines, based on the privacy configuration of the second UE, that the SL positioning results of at least two second UEs are allowed to be disclosed.

[0340] In some embodiments, the second request is a second request sent by the first network node when it determines, based on the privacy configuration of the second UE, that the SL positioning results of at least two second UEs are allowed to be disclosed and when it determines that the SL positioning results of at least two second UEs are not disclosed to any UE.

[0341] In the embodiment of the present disclosure, if the second network node receives the second request sent by the first network node, it may not receive the first request sent by the first network node.

[0342] S4103b: Receive a response to the first request.

[0343] In some embodiments, a response to the first request sent by the first network node is received.

[0344] In some embodiments, the response to the first request may be a failure response or a success response to the first request.

[0345] In some embodiments, the first request failure response may further include a failure reason. For example, the failure reason may indicate that the privacy configuration indicates that the SL positioning result is not allowed to be disclosed.

[0346] In some embodiments, a successful response to the first request may indicate acceptance of the SL positioning measurement requested by the first request. If the second UE's privacy configuration indicates that the SL positioning result is permitted to be disclosed to any UE, this is equivalent to indicating that the second UE's privacy configuration alone can determine that the second UE is permitted to disclose the SL positioning result to the first UE. Therefore, the first network node does not need to trigger the second network node again to initiate authentication of whether the first UE is permitted to obtain the second UE's SL positioning result. In this case, the second network node can directly receive a response to the first request without receiving the second request.

[0347] S4104: Send the fourth request.

[0348] In some embodiments, the optional implementation of S4104 can be found in Figure 2A S2104 of the corresponding embodiment.

[0349] S4105: Receive the verification result of the second UE.

[0350] S4106: Determine whether to disclose the SL positioning results of at least two second UEs to the first UE.

[0351] In some embodiments, after receiving the verification results of each second UE, the second network node determines whether each second UE allows its own SL positioning results to be disclosed to the first UE. Exemplarily, if each second UE allows the SL positioning results to be disclosed to the first UE, it is determined that the SL positioning results of the at least two second UEs are agreed to be disclosed to the first UE. Exemplarily, if at least one second UE does not agree to disclose the SL positioning results to the first UE, it is determined that the SL positioning results of the at least two second UEs are not agreed to be disclosed to the first UE.

[0352] In some embodiments, the optional implementation of S4106 can be found in Figure 2A S2106 of the corresponding embodiment.

[0353] S4107: Send a response to the second request.

[0354] In some embodiments, the response to the second request is a successful response to the first request or a failed response to the second request.

[0355] In some embodiments, a successful response to the second request indicates that at least two second UEs allow (or agree) to disclose the SL positioning result to the first UE.

[0356] In some embodiments, the failed response to the second request indicates that at least two second UEs do not allow (ie, do not agree) to disclose the SL positioning result to the first UE.

[0357] In some embodiments, the failure response to the second request will carry a failure reason. The failure reason may indicate the reason for not agreeing to disclose the SL positioning results of at least two second UEs to the first UE. For example, the failure reason may include but is not limited to one or more second UEs not agreeing to disclose the SL positioning results to the first UE.

[0358] In some embodiments, in the embodiments of the present disclosure, the second network node determines whether to finally allow the SL positioning results of at least two second UEs to be disclosed to the first UE based on the verification results of each second UE. In this way, when the first network node receives a response to the first request, it can know whether it is necessary to trigger the SL positioning measurement between at least two second UEs.

[0359] In some embodiments, the optional implementation of S4107 can be found in Figure 2A S2107 of the corresponding embodiment.

[0360] S4108: Initiate SL positioning measurement between at least two second UEs.

[0361] In some embodiments, the optional implementation of S4108 can be found in Figure 2A S2108 of the corresponding embodiment.

[0362] It is worth noting that S4101, S4102, S4103a and S4103b are optional steps. It is assumed that the current second network node is the serving node of the second UE. For example, the current second network node is the serving AMF of the second UE and the reception of the third request and the sending of the first request can be performed by the second network node of the first UE.

[0363] It is worth noting that S4104 to S4108 are optional steps. Assuming that the current second network node is the serving node of the first UE and not the serving node of the second UE, the second network node may execute S4101, S4102 and S4103a, or the second network node may execute S4101, S4102 and S4103b, and S4104 to S4108 may be executed by the second network node (AMF) of the second UE.

[0364] In some embodiments, this solution may be applicable to an application scenario where multiple second UEs have the same second network node.

[0365] like Figure 4B As shown, an embodiment of the present disclosure provides a privacy verification method during positioning measurement, wherein the method is performed by a second network node. The method may include:

[0366] S4201: Receive the third request.

[0367] In some embodiments, the second network node receives the third request sent by the first UE, or the second network node receives the third request sent by the second UE.

[0368] In some embodiments, the first UE is a client UE. The client UE may be a UE that requests, uses, or consumes the SL positioning result. The second UE may be a UE that participates in the SL positioning service to obtain the SL positioning result. For example, the third request may indicate that the first UE requests the SL positioning results of at least two second UEs. The SL positioning result may be a relative positioning result between the two second UEs.

[0369] In some embodiments, the third request indicates that the first user equipment UE requests sidelink (SL) positioning measurements between two second UEs.

[0370] In some embodiments, the third request may include but is not limited to various non-access stratum (NAS) messages.

[0371] In some embodiments, the third request may include but is not limited to a SL positioning service request message.

[0373] In some embodiments, the third request may include, but is not limited to, information about the first UE and information about the second UE. For example, the information about the first UE may include, but is not limited to, identification information of the first UE. For example, the identification information of the first UE may include, but is not limited to, a user information identifier (User Info ID) and / or a subscription permanent identifier (SUPI).

[0374] S4202: Send the first request.

[0375] In some embodiments, the second network node sends the first request to the first network node.

[0376] In some embodiments, the first request includes information of the first UE and information of at least one of the at least two second UEs.

[0377] In some embodiments, the second network node may be a core network node. Exemplarily, the second network node may include, but is not limited to, an Access Management Function (AMF). Exemplarily, if the third request originates from a first UE, the second network node may be the serving AMF for the first UE. If the third request originates from a second UE, the second network node may be the serving AMF for the second UE.

[0378] In some embodiments, the second network node sends the first request to the first network node according to the third request. For example, after receiving the third request, the second network node sends the first request according to the first network node.

[0379] In some embodiments, the first network node may also be a core network node. Exemplarily, the first network node may include but is not limited to: a Gateway Mobile Location Center (GMLC).

[0380] In some embodiments, the first request may include, but is not limited to, Ngml_Location_ProvideRangingRequest.

[0385] In some embodiments, the second request includes information of the first UE and information of at least two second UEs.

[0386] In some embodiments, the second request is a second request sent when the first network node determines, based on the privacy configuration of the second UE, that the SL positioning results of at least two second UEs are allowed to be disclosed.

[0387] In some embodiments, the second request is a second request sent by the first network node when it determines, based on the privacy configuration of the second UE, that the SL positioning results of at least two second UEs are allowed to be disclosed and when it determines that the SL positioning results of at least two second UEs are not disclosed to any UE.

[0388] S4204: Send the fourth request.

[0389] In some embodiments, the optional implementation of S4204 can be found in Figure 2B S2204 of the corresponding embodiment.

[0390] S4205: Receive the verification result of the second UE.

[0391] S4206: Send a response to the second request.

[0392] In some embodiments, the second network node sends a second request response to the first network node.

[0393] In some embodiments, the response to the second request includes a verification result provided by at least one second UE, where the verification result indicates whether the corresponding second UE allows the SL positioning result to be disclosed to the first UE.

[0394] In some embodiments, the response to the second request may include a verification result provided by each of the at least two second UEs.

[0395] S4207: Receive a response to the first request.

[0396] In some embodiments, the response to the first request includes: a successful response to the first request and / or a failed response to the first request.

[0397] In some embodiments, a successful response to the first request indicates a determination to perform the SL positioning measurement corresponding to the first request.

[0398] In some embodiments, the failure response to the first request may indicate a determination not to perform (i.e., reject) the SL positioning measurement corresponding to the first request. In some embodiments, the failure response to the first request may also include a failure reason. For example, the failure reason may indicate that the privacy configuration indicates that the SL positioning result is not allowed to be disclosed.

[0399] S4208: Initiate SL positioning measurement between at least two second UEs.

[0400] In some embodiments, based on a successful response to the first request, SL positioning measurements are initiated between at least two second UEs.

[0401] Determine whether to disclose the SL positioning results of at least two second UEs to the first UE.

[0402] In some embodiments, after receiving the verification results of each second UE, the second network node determines whether each second UE allows its own SL positioning results to be disclosed to the first UE. Exemplarily, if each second UE allows the SL positioning results to be disclosed to the first UE, it is determined that the SL positioning results of the at least two second UEs are agreed to be disclosed to the first UE. Exemplarily, if at least one second UE does not agree to disclose the SL positioning results to the first UE, it is determined that the SL positioning results of the at least two second UEs are not agreed to be disclosed to the first UE.

[0403] It should be noted that the second network node that sends the first request and the second network node that receives the second request may be the same or different.

[0404] like Figure 5A As shown, an embodiment of the present disclosure provides a privacy verification method during positioning measurement, wherein the method is performed by a UE, which can be a first UE or a second UE. The method includes:

[0405] S5101: Send the third request.

[0406] In some embodiments, the third request is used by the first UE to request sidelink SL positioning measurements between at least two second UEs.

[0407] In some embodiments, the third request includes information of the first UE and information of at least the second UE of the at least two second UEs.

[0408] In some embodiments, the information of the first UE is used by at least two second UEs to determine whether to allow disclosure of the SL positioning result to the first UE.

[0409] In some embodiments, the UE sends a third request to the second network node.

[0410] In some embodiments, if the first UE is within the coverage of the network and / or the first UE has established a NAS connection with the network side, the first UE may send a third request to its own second network node.

[0411] In some embodiments, if a first UE is out of network coverage and / or does not have an established NAS connection with the network, the first UE may request at least one second UE to send a third request to the second network node. If the second UE sends the third request, the second UE may obtain information about the first UE and / or information about other second UEs from the first UE based on a connection such as the SL.

[0412] In some embodiments, the information of the first UE includes a user information identifier of the first UE.

[0413] like Figure 5BAs shown, the embodiment of the present disclosure provides a privacy verification method during positioning measurement, wherein the method is performed by a second UE. The method includes:

[0414] S5201: Receive the fourth request.

[0415] In some embodiments, the fourth request includes at least information of the first UE.

[0416] In some embodiments, a first UE requests SL positioning measurements between at least two second UEs.

[0417] In some embodiments, a fourth request sent by the second network node is received.

[0418] S5202: Send verification results.

[0419] In some embodiments, the verification result may be carried in the response to the fourth request.

[0420] In some embodiments, the verification result to be sent is obtained according to the setting of the second UE.

[0421] In some embodiments, the second UE may display the information of the first UE and / or display that the first UE wants to obtain the SL positioning result of the second UE on the UI, and generate a verification result based on the user operation performed on the UI. For example, if the user operation indicates that the first UE agrees to obtain the SL positioning result of the second UE, the verification result indicates that the first UE is allowed to obtain the SL positioning result of the second UE; otherwise, the verification result may indicate that the first UE is not allowed to obtain the SL positioning result of the second UE.

[0422] Example 1:

[0423] like Figure 6A As shown, the embodiment of the present disclosure provides a method, which may include:

[0424] 1. Sending a SL positioning service request: If there is a NAS connection, the client UE can directly send a SL positioning service request to the network. If the client UE does not have a NAS connection, it can select one of the measured UEs to send a SL positioning service request to the selected UE (ie, UE1).

[0425] 2. UE1 that receives the SL positioning service request determines that it wants to perform the SideLink-Mobile Originated-Location Rquest (SL-MO-LR), and then sends the SL-MO-LR request for the supplementary service to the AMF providing the service through the Uplink Non Access Stratum TRANSPORT (UL NAS TRANSPORT) message. The SL-MO-LR request includes at least the information of the UE under test, that is, the information of UE1 and UE2. And the SL-MO-LR may include information about the service type. The information about the service type may indicate the service involved. For example, the SL positioning measurement service can be used for the client UE to request the SL positioning measurement of the UE under test, or the client UE to request the SL positioning result of the UE under test. The SL positioning client UE information can be included in the UL NAS transmission message.

[0426] 3. Based on the information received from UE1, the AMF determines whether to trigger UE privacy verification. The AMF selects the GMLC and forwards the SL-MO-LR request to the GMLC via the Ngmlc_Location_ProvideRanging Request. The Ngmlc_Location_ProvideRanging Request includes at least client UE information and measured UE information. The measured UE information may include information on UE1 and / or UE2. The information received by the AMF from UE1 may also include, but is not limited to, at least one of the following: service type information, client UE information, and information on UE1 and / or UE2.

[0427] 4.GMLC sends Nudm_SDM_GET to UDM. For example, based on the information received from AMF (information of the UE under test), GMLC obtains the privacy profile of the UE under test from UDM.

[0428] 5. For the client UEs, verify the privacy profiles of UE1 and / or UE2. Based on the information received from the AMF (information of the UE under test), the GMLC retrieves the privacy profiles of the UE under test from the UDM and determines whether the privacy profiles allow disclosure of the SL positioning results. The GMLC checks the privacy profiles of UE1 and UE2. If the privacy profiles indicate that disclosure to the client UEs is allowed, the GMLC decides to proceed to step 6a. If the privacy profiles indicate that disclosure to any client UEs is not allowed, the GMLC decides to proceed to step 6b.

[0429] 6a.GMLC sends a request (Namf_Location_ProvidePositioningInfo) containing the client UE information to AMF to trigger step 7a.

[0430] 6b.GMLC returns a Ngmlc_Location_ProvideRanging response to AMF, which indicates that the failure reason may include but is not limited to UE1 and / or UE2 not allowing the SL positioning result to be disclosed to any client UE, thereby triggering step 7b.

[0431] 7a. The AMF sends a NAS Location Invoke Request to UE1 and / or UE2, respectively, containing the client UE information. Step 7a may include 7a-1 and 7a-2. 7b. The AMF returns a supplementary service SL-MO-LR response to UE1 in a DL NAS TRANSPORT message, including a failure cause. The failure cause may indicate, but is not limited to, that UE1 and / or UE2 does not allow the SL positioning result to be disclosed to any client UE.

[0432] 8. UE1 and / or UE2 checks whether the result of its participation in SL positioning is allowed to be exposed to the specific client UE identified by the client UE information, and returns the verification result to the AMF respectively. Step 8 may include step 8-1 and step 8-2.

[0433] 9. The AMF determines to continue or stop the SL positioning measurement based on the verification results of UE1 and / or UE2. For example, the AMF decides to make a SL positioning request or return a response to the GMLC and UE1 based on the verification results from UE1 and / or UE2.

[0434] In some embodiments, step 9 may include:

[0435] 9b-1. If UE1 and / or UE2 do not allow the SL positioning result to be disclosed to a specific client UE, the AMF shall return a Namf_Location_ProvidePositioningInfo response to the GMLC, which may indicate the failure reason. The failure reason may include: UE1 and / or UE2 do not allow the SL positioning result to be disclosed to a specific client UE.

[0436] 9b-2. If UE1 and / or UE2 do not allow the SL positioning result to be disclosed to the specific client UE, the AMF shall return a supplementary service SL-MO-LR response to UE1 in the DLNAS TRANSPORT message, which may include the failure cause. The failure cause may include but is not limited to UE1 and / or UE2 not allowing the SL positioning result to be disclosed to the specific client UE.

[0437] 10: Other steps of SL positioning measurement. For example, if UE1 and / or UE2 allow disclosure to specific client UEs, the AMF further sends the request to the LMF and performs the rest of the SL positioning process.

[0438] Example 2:

[0439] like Figure 6B As shown, the embodiment of the present disclosure provides a method, which may include:

[0440] Steps 1 to 8 are the same as steps 1 to 8 in Example 1. Steps 9 to 11 are alternative methods to steps 9 to 10 in Example 2.

[0441] 9.AMF returns the Namf_Location_ProvidePositioningInfo response together with the verification result of UE1 and / or UE2 to GMLC.

[0442] 10. The GMLC decides to continue the ranging request or return a response to the AMF based on the verification results from UE1 and / or UE2.

[0443] 11. Based on the verification results of UE1 and / or UE2, determine whether to continue or stop the SL positioning measurement.

[0444] This step 11 may include at least one of the following:

[0445] 11a. If UE1 and / or UE2 allow disclosure to specific client UEs, the GMLC will send a Namf_Location_ProvidePositioningInfo request to the AMF again and perform the rest of the SL positioning procedure.

[0446] 11b-1. If UE1 and / or UE2 do not allow the SL positioning result to be disclosed to a specific client UE, the GMLC will return an Ngmlc_Location_ProvideRanging response to the AMF, which may indicate the reason for the failure. The specific reason for the failure may include but is not limited to that UE1 and / or UE2 do not allow the SL positioning result to be disclosed to a specific client UE.

[0447] 11b-2. After receiving the Ngmlc_Location_ProvideRanging response from the GMLC, the AMF returns a supplementary service SL-MO-LR response to UE1 in a DL NASTRANSPORT message, which may indicate the reason for the failure. The specific reason for the failure may include but is not limited to: UE1 and / or UE2 does not allow the SL positioning result to be disclosed to the specific client UE.

[0448] The privacy verification method during positioning measurement provided by the embodiment of the present disclosure involves UE, AMF and / or GMLC, etc.

[0449] For example, the UE (UE1) should be able to include the SL positioning client UE information in the UL NAS transmission message. And / or, the UE (UE1 and / or UE2) should be able to receive the client UE information from the AMF for privacy verification. And / or,

[0450] The UE (UE1 and / or UE2) shall be able to verify whether disclosure is allowed or not allowed to a specific client UE identified by the client UE information. And / or, the UE (UE1 and / or UE2) shall be able to return the verification result to the AMF. And / or, the UE (UE1) shall be able to receive the privacy verification failure reason from the AMF.

[0451] For example, the AMF shall be able to receive the client UE information in the Namf_Location_ProvidePositioningInfo request from the GMLC. And / or, the AMF shall be able to send the client UE information to the UE in the NAS_Location_Notification_Invoke Request. And / or, the AMF shall be able to decide whether to proceed with the SL positioning request or return a failure based on the UE's verification result.

[0452] The AMF shall be able to send the privacy verification failure cause to the GMLC via the Namf_Location_ProvidePositioningInfo response. And / or, the AMF shall be able to receive the privacy verification failure cause from the GMLC via the Ngmlc_Location_ProvideRanging response. And / or, the AMF shall be able to send the privacy verification failure cause to the UE.

[0453] Exemplarily, the GMLC shall be able to check whether the UE privacy profile allows or does not allow disclosure to any client UE. And / or, the GMLC shall be able to determine whether privacy verification with the UE is required in order to provide services to a specific client UE based on the UE privacy profile and the received client UE information. And / or, the GMLC shall be able to send the client UE information in the Namf_Location_ProvidePositioningInfo Request to the AMF. And / or, the GMLC shall be able to send the privacy verification failure reason to the AMF through the Ngmlc_Location_ProvideRanging response. And / or, the GMLC shall be able to receive the verification result of the UE from the AMF through the Namf_Location_ProvidePositioningInfo response. And / or,

[0454] The GMLC shall be able to receive the privacy verification failure reason from the AMF via the Namf_Location_ProvidePositioningInfo response.
