[0363] In some embodiments, the above method can include the method of the above embodiments of the communication system side, network element side, etc., which will not be described here.

[0364] In the communication method proposed in embodiments of the present disclosure, the sensing subscription data can be stored in a unified data management network element (UDM). The sensing subscription data indicates whether the UE is authorized to use the sensing service. The sensing subscription data can include a UE sensing privacy profile to indicate the privacy preference of the UE, for example, which is allowed, or conditionally allowed or not allowed to obtain the location information of the UE.

[0365] Embodiments of the present disclosure define a UE-aware privacy profile in the UDM, and the UE-aware privacy profile can be provided to other network functions (NFs) through subscription and notification.

[0366] The UE-aware privacy profile can include an awareness privacy indication / awareness indication, allowed awareness roles, allowed service areas (or awareness areas), allowed awareness time periods, allowed privacy classes, allowed Radio Access Technologies (RATs), allowed device types, and thresholds of awareness confidence and / or awareness accuracy levels.

[0367] The awareness privacy indication / awareness indication is used to indicate whether the awareness request for the UE is allowed or prohibited and the kind of allowed or prohibited. It can be a global setting (for all awareness consumers), for example, no awareness allowed; awareness allowed. It can also allow awareness for certain specific types of awareness requests and not allow awareness for other specific types of awareness requests. For example, only for bistatic sensing allowed, or only for monostatic sensing allowed; only for user plane awareness allowed, or only for control plane awareness allowed.

[0368] The allowed awareness roles indicate which awareness roles are allowed, for example, allowed for the sender and / or receiver and / or processor.

[0369] The allowed awareness areas indicate the location where the awareness service is allowed, which can be described by the shape and shape description of the area, or can be described by a cell, an awareness Tracking Area ID (TAI), latitude and longitude.

[0370] The allowed awareness time periods indicate the time when the awareness service is allowed, and the allowed awareness time periods include a start time and an end time, which can also be one-time or periodic.

[0371] The allowed awareness RATs indicate which awareness RATs are allowed, for example, 3GPP, non-3GPP, or both.

[0372] The allowed device types indicate which consumers / clients are allowed for the UE. For example, the UE can only allow the awareness service for a car, and not allow the awareness service for an Internet of Things (IoT) device.

[0373] The threshold of sensing confidence and / or sensing accuracy level is used to indicate the confidence and / or accuracy level of the estimated sensing result. The threshold can be a range or a specific value.

[0374] In the embodiments of the present disclosure, the UE can report a sensing privacy profile.

[0375] In the embodiments of the present disclosure, the NF consumer can request to be notified about expected UE behavior.

[0376] FIG. 8A is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 8A, the embodiments of the present disclosure relate to a communication method, and the method comprises:

[0377] In step S8101, the NF sends a subscription data subscription request to the UDM.

[0378] In some embodiments, the NF can be a sensing consumer, and the NF can subscribe to UDM notification of UE sensing privacy profile update.

[0379] For example, the NF sends a subscription data subscription request (Nudm_SDM_Subscribe request) to the UDM to subscribe to UDM notification of sensing privacy profile update.

[0380] In some embodiments, the NF can include one of a gateway mobile location center (GMLC), a network exposure function (NEF), a sensing function (SF), a sensing data management function (SDMF), a location management function (LMF), and an enhanced LMF.

[0381] In some embodiments, the subscription data subscription request sent by the NF to the UDM can include at least one of a subscription data type, a key for each subscription data type, and an immediate reporting indication.

[0382] The subscription data type can be sensing subscription data and / or a UE sensing privacy profile.

[0383] The immediate reporting indication can be included in the subscription data subscription request, so that the UDM can make a first report after receiving the subscription request.

[0384] For example, when the SF / LMF / SDMF selects a sensing entity and / or a sensing sender and / or a receiver for a sensing service, the SF / LMF / SDMF can subscribe to the profile, the SF / LMP / SDMF obtains the UE sensing subscription data and / or the UE sensing privacy profile to select the appropriate sensing entity and / or sender and / or receiver.

[0385] At step S8102, the UDM sends a subscription data subscription response to the NF.

[0386] In some embodiments, the UDM sends a response message to the NF consumer. If an immediate report indication is included in the subscription request, the response message includes the subscribed data. This step can also be omitted.

[0387] For example, the NF sends a subscription data subscription response (Nudm_SDM_Subscribe response) to the UDM.

[0388] At step S8103, the UE sends a UE sensing privacy creation or update request to the AMF.

[0389] In some embodiments, if the UE has generated or updated the UE sensing privacy indication / UE sensing privacy profile, the UE sends the UE sensing privacy indication / UE sensing privacy profile to the AMF.

[0390] In some embodiments, the message sent by the UE to the AMF can be a UE sensing privacy creation / update request.

[0391] In some embodiments, the UE sends an uplink non-access stratum transport (UL NAS TRANSPROT) message to the AMF, which can include the UE sensing privacy creation / update request (UE sensing privacy indication / UE sensing privacy profile).

[0392] At step S8104, the AMF sends a parameter provision update request based on the UDM service interface to the UDM.

[0393] In some embodiments, the AMF sends a parameter provision update request (Nudm_ParameterProvision_Update) based on the UDM service interface to the UDM, which can include at least one of an AMF ID, a UE ID, a UE sensing privacy indication, a UE sensing privacy profile.

[0394] In some embodiments, the AMF invokes the Nudm_ParameterProvision_Update service operation to the UDM, and sends the received UE sensing privacy indication / UE sensing privacy profile to the UDM.

[0395] Step S8105, the UDM sends a data management update request based on the UDR service interface to the UDR.

[0396] In some embodiments, the UDM updates the UE awareness privacy profile in the UDR either locally or by invoking a data management update request based on the UDR service interface (Nudr_DM_Update) (SUPI, subscription data) service operation. The request can include at least one of the UE ID, the UE awareness privacy indication, the UE awareness privacy profile.

[0397] Step S8106, the AMF sends a UE awareness privacy creation or update request acknowledgement to the UE.

[0398] In some embodiments, the AMF sends a downlink non-access stratum transport (DL NAS TRANSPROT) message to the UE, which includes the UE awareness privacy creation / update request acknowledgement.

[0399] Step S8107, the UDM sends a data management notification message based on the UDM service interface to the NF.

[0400] The UDM notifies the NF consumers (e.g., GMLC, NEF, SF, SDMF, and enhanced LMF) that have subscribed to the notification of the updated UE awareness privacy indication / UE awareness privacy profile through a data management notification message based on the UDM service interface (Nudm_SDM_Notification_Notify).

[0401] The NF consumer receives the UE awareness privacy indication / UE awareness privacy profile / UE awareness subscription data from the UDM and stores the received information.

[0402] For example, when the SF / LMF / SDMF needs to select an awareness sender and / or receiver for an awareness task, the SF / LMF / SDMF can use the locally stored UE awareness privacy indication / UE awareness privacy profile / UE awareness subscription data.

[0403] Step S8108, the NF sends a subscription data unsubscription message to the UDM.

[0404] In some embodiments, the NF consumer can also unsubscribe from the UDM notification of the UE awareness privacy indication / UE awareness privacy profile update.

[0405] In some embodiments, the NF consumer sends a subscription data unsubscription message (Nudm_SDM_Unsubscribe) to the UDM, which includes the subscription data type and the key for each subscription data type.

[0406] At step S8109, the UDM sends a subscription data cancel subscription response to the NF.

[0407] In embodiments of the present disclosure, the AF can provide a perception privacy profile.

[0408] In embodiments of the present disclosure, the NF consumer can request to be notified about application-specific expected UE behavior.

[0409] FIG. 8B is an interaction diagram of a communication method, according to embodiments of the present disclosure. As shown in FIG. 8B, embodiments of the present disclosure relate to a communication method, the method comprising:

[0410] At step S8201, the NF sends a subscription data subscription request to the UDM.

[0411] In some embodiments, the NF can be a perception consumer, and the NF can subscribe to UDM notifications of UE perception privacy profile updates.

[0412] In some embodiments, the NF can include one of a GMLC, a SF, a SDMF, an LMF, and an enhanced LMF.

[0413] For example, the NF sends a subscription data subscription request (Nudm_SDM_Subscribe request) to the UDM to subscribe to UDM notifications of perception privacy profile updates.

[0414] In some embodiments, the NF consumer can request to be notified about expected UE behavior parameters and / or application-specific expected UE behavior parameters.

[0415] At step S8202, the UDM sends a subscription data subscription response to the NF.

[0416] In some embodiments, the UDM sends a response message to the NF consumer. If an immediate report indication is included in the subscription request, the response message includes the subscribed data. This step can also be omitted.

[0417] For example, the NF sends a subscription data subscription response (Nudm_SDM_Subscribe response) to the UDM.

[0418] At step S8203, the AF sends a parameter provision creation or update or deletion request based on a NEF service interface to the NEF.

[0419] In some embodiments, the AF provides the UE awareness privacy indication / UE awareness privacy profile / UE awareness subscription data to the NEF in a parameter provision create (Nnef_ParameterProvision_Create) request or a parameter provision update (Nnef_ParameterProvision_Update) request or a parameter provision delete (Nnef_ParameterProvision_Delete) request based on the NEF service interface.

[0420] In some embodiments, the AF sends a parameter provision create request or a parameter provision update request or a parameter provision delete request based on the NEF service interface to the NEF, including at least one of the AF ID, a transaction reference ID, a UE ID (e.g., GPSI) or an external group ID, the UE awareness privacy indication / UE awareness privacy profile / UE awareness subscription data, a data network name (DNN), and network slice selection assistance information (S-NSSAI) in the request.

[0421] At step S8204, the NEF sends a parameter provision create or update or delete request based on the UDM service interface to the UDM.

[0422] In some embodiments, the NEF confirms whether the AF is allowed to perform the requested service operation by checking the AF ID. If the AF is authorized by the NEF to provide the parameters, the NEF requests to create, update and store, or delete the provided parameters as part of the subscription user data through the Nudm_ParameterProvision_Create request message or the Nudm_ParameterProvision_Update request message or the Nudm_ParameterProvision_Delete request message.

[0423] In some embodiments, if the received awareness area is contained in the UE awareness privacy indication / UE awareness privacy profile / UE awareness subscription data, the NEF further maps the geographic information (e.g., shape of the area, and / or shape description, and / or longitude and latitude) to a list of TAs.

[0424] In some embodiments, the NEF sends to the UDM a Nudm_ParameterProvision_Create request or a Nudm_ParameterProvision_Update request or a Nudm_ParameterProvision_Delete request including at least one of the AF ID, the UE ID (e.g. GPSI) or the external group ID, the UE awareness privacy indication / UE awareness privacy profile / UE awareness subscription data, the DNN, the S-NSSAI.

[0425] At step S8205, the UDM sends to the UDR a data management query request based on the UDR service interface.
