Description

Positioning perception method, device, equipment, storage medium and chip

Technical Field

The present disclosure relates to the field of communication positioning, and in particular to a positioning perception method, device, equipment, storage medium and chip.

Background technique

Wireless sensing technology aims to obtain relevant characteristic information of remote objects without physical contact. It can obtain meaningful data information such as object characteristics by analyzing the sensing data of the object and its surroundings. For example, radar is a widely used wireless sensing technology that uses radio waves to determine the distance, angle or instantaneous linear speed of an object.

Integrated sensing and communication in 3GPP (3rd Generation Partnership Project) 5G systems refers to the sensing capabilities provided by the 5G NR wireless communication system and related infrastructure used for communication, and the sensing information can be obtained through RF sensors and/or non-RF-based sensors. Integrated sensing and communication may involve: (1) communication-assisted sensing scenarios, for example, providing sensing services to UE (User Equipment) through 5G communication systems; (2) sensing-assisted communication scenarios, for example, improving the communication services of 5G systems through sensing information related to communication channels or environments, where the sensing information can be used to assist in radio resource management, interference suppression management, beam management, mobility management, etc.

In multiple market segments and verticals, wireless communication-based sensing services can help smart transportation, aviation, enterprises, smart cities, smart homes, factories, consumer applications, XR (Extended Range) and public administration departments. Mobile operators can play an important role in providing customers with integrated sensing and communications based on 5GS, including management and control based on 5G sensing services, especially for the perception of infrastructure-assisted environment, remote control driving based on infrastructure, high-definition map collection and sharing, remote control driving, etc., sensing services can provide technical support.

In related technologies, mobile networks can support the positioning service function of UE, identify and report the current location of UE in a standard format (e.g., geographic coordinates, location information, etc.), and provide the location information to users, ME (Mobile Equipment), network operators, service providers, value-added service providers, and PLMN (Public Land Mobile Network) for internal operations. However, it is impossible to support services such as intelligent control, intelligent transportation, XR, and unmanned driving based solely on the location information. Therefore, providing a sensing solution in the mobile network so that the mobile network can provide perception services for the UE has become a technical problem that needs to be solved urgently.

FIG1 is a flow chart of a positioning perception method according to an exemplary embodiment. As shown in FIG1 , the method is applied to a SAF (Sensing Application Function) network element and includes the following steps.

In step S101, a positioning perception request sent by a perception requesting end is received, where the positioning perception request is used to perceive attribute information of a user device.

It is worth mentioning that this embodiment can be applied to a wireless communication network, through which a communication-assisted sensing service based on the corresponding UE is provided to the perception request end. For example, the communication-assisted sensing service can be applied to the following scenarios: (1) Real-time environmental monitoring: Reconstruct environmental maps using wireless signals to improve the positioning accuracy of UEs and enable environmental-related applications, such as implementing a series of real-time monitoring-related applications, including dynamic 3D maps for assisted driving, pedestrian flow statistics, intrusion detection, and traffic detection; (2) Autonomous driving vehicles or drones: Autonomous driving vehicles or drones have functional requirements for communication-assisted sensing, for example, autonomous driving vehicles or drones Human-machine interaction should support the detection and avoidance of obstacles. At the same time, autonomous vehicles or drones should have the ability to monitor path information, such as determining the current road condition based on perception-assisted data, so as to select a suitable route and comply with traffic rules. (3) Air pollution monitoring: The quality of the received wireless signal shows different attenuation characteristics with the changes in air humidity, air particulate matter (PM) concentration, carrier frequency, etc., which can be used for weather or air quality detection. (4) Indoor health care and intrusion detection: By analyzing the wireless communication signal of the UE, the user's breathing rate estimation, breathing depth estimation, apnea detection, vital sign monitoring and indoor intrusion detection can be achieved. (5) The sensing of wireless communication channels and environments can further improve the performance of the communication system, for example: sensing the position and channel environment of the UE, reducing the beam scanning range, and shortening the beam training time; sensing the position, speed, motion trajectory and channel environment of the UE for beam prediction, reducing the overhead of beam measurement and the delay of beam tracking; sensing the attributes and channel environment of the UE to improve the performance of channel estimation, etc. This embodiment proposes a perception solution, so that the mobile network can provide perception services for the UE and implement the above application scenarios based on the perception services.

By way of example, this embodiment is applied to a SAF network element, which is used to receive a positioning perception request from a perception request end. The perception request end is a terminal device that needs to obtain perception information of a perception object (e.g., an unmanned vehicle, a mobile phone, a smart home appliance, etc.). The terminal device may be a server of a road management party or a server of a smart home appliance management party. Among them, a positioning perception protocol is configured in the perception object. When a positioning perception is requested, corresponding positioning perception data may be sent to the perception request end based on the positioning perception protocol. By way of example, the perception object may be a UE equipped with 3GPP (3rd Generation Partnership Project). The SAF network element may communicate wirelessly with the perception request end to receive a positioning perception request sent by the perception request end. The positioning perception request includes identification information of the UE and relevant attribute information of the UE requested by the perception request end. The perception request end may determine the location information, speed information, direction information, shape information, and environmental information of the environment in which the UE is located through the attribute information. The perception request end may determine the attributes of the UE and the environmental attributes of the environment in which the UE is located based on the attribute information fed back by the UE.

Optionally, the attribute information includes: at least one of location information, speed information, shape information, size information or direction information of the user equipment.

For example, in this embodiment, the perception request end sends the positioning perception intention through the SAF network element, and the user obtains the attribute information of the UE. For example, in the application scenario of autonomous driving control, the perception request end can be the server corresponding to the road management party, and the UE is a 3GPP monitoring device configured on the autonomous driving vehicle. In order to facilitate the road management position to monitor the operating status of the autonomous driving vehicle, it is necessary to obtain the speed, direction, position, mileage, vehicle size and other information of the autonomous driving vehicle in order to supervise the autonomous driving vehicle. The server corresponding to the road management party sends the positioning perception request to the SAF network element, performs positioning perception services through the assistance of the mobile network, and determines the attribute information of the UE based on the perception information fed back by the mobile network, wherein the attribute information includes the location information and direction information of the autonomous driving vehicle. Speed information, etc.

In step S102, a positioning awareness request is sent to the mobile positioning center gateway GMLC, and the positioning awareness request is used to instruct the GMLC to feedback the awareness willingness of the user equipment according to the positioning awareness request.

For example, in this embodiment, after the SAF network element receives the positioning perception request sent by the perception request end, it sends the positioning perception request to the GMLC (Gateway Mobile Location Centre) to make a judgment on the positioning perception request through the GMLC.

Optionally, in another implementation manner, the above step of sending the location awareness request to the GMLC includes:

The positioning awareness request is sent to the network element open function device NEF, so that the positioning awareness request is sent to the GMLC through the NEF.

For example, in this embodiment, the SAF network element can be set in the LCS (Location Services) architecture. Figure 2 is a structural diagram of an LCS perception service architecture according to an exemplary embodiment. As shown in Figure 2, the SAF network element in the LCS perception service architecture can be connected to the GMLC (Gateway Mobile Location Centre) and LRF (Location Retrieval Function) gateway through the Le interface as an LCS client (LCS Client) in the LCS perception service architecture, and is used to send the received positioning perception request to the GMLC; it can also be connected to the NEF (Network Exposure Function) through the N33 interface as an AF (Access Facilities) to send the received positioning perception request to the NEF, and send the positioning perception request to the GMLC through the NEF.

For example, the GMLC determines the identification information of the UE according to the positioning perception request, and determines the initial perception willingness of the UE according to the identification information. When it is determined that the UE runs positioning perception, the positioning perception request is sent to the AMF (Access and Mobility Management Function) network element. It is worth mentioning that the privacy configuration data corresponding to each UE can be configured in the GMLC, and the privacy configuration data can include the time conditions, regional conditions, service type conditions, etc. that the UE allows for positioning perception, and establishes a mapping relationship between the UE corresponding identification and the privacy configuration data. After receiving the positioning perception request sent by the SAF network element, the GMLC determines the identification corresponding to the UE through analysis, determines the privacy configuration data corresponding to the UE according to the identification, and determines the initial perception willingness of the UE based on the privacy configuration data; when the positioning perception request sent by the SAF network element meets the initial perception willingness of the UE, the positioning perception request is sent to the AMF network element; when the positioning perception request sent by the SAF network element does not meet the initial perception willingness of the UE, the positioning perception request is rejected, and the perception rejection information is fed back to the SAF network element.

For example, after GMLC receives the UE's positioning perception request, it determines that the perception request end needs to perceive the UE's location information and direction information at 10:10. GMLC determines the UE's initial perception intention through the UE's identifier, indicating that the UE is between 10:00 and 14:00, and perception is not allowed. Then GMLC will reject the positioning perception request and feedback the perception rejection information to the SAF network element.

After the positioning perception request meets the initial perception intention of the UE, the GMLC sends the positioning perception request to the AMF network element. After the AMF network element receives the positioning perception request sent by the GMLC, it needs to obtain the attribute information of the UE in the positioning perception request, perceives the relevant attribute information of the UE through the corresponding positioning perception device, generates perception information, and sends the perception information to the GMLC. The GMLC generates the perception intention of the UE based on the perception information feedback from the AMF network element.

Optionally, in another embodiment, the above steps send a positioning awareness request to GMLC, and the positioning awareness request is used to instruct GMLC to send a positioning awareness request to an AMF network element when the user equipment allows positioning awareness, and receive the perception information sent by the AMF network element, and generate a perception intention based on the perception information, including: sending a positioning awareness request to GMLC, and the positioning awareness request is used to instruct GMLC to determine an identifier of the user equipment according to the positioning awareness request, and send the identifier to a unified data management (UDM) network element; the identifier is used to indicate that the UDM network element determines the target privacy configuration data corresponding to the user equipment from preset privacy configuration data according to the identifier; the positioning awareness request is also used for GMLC to send a positioning awareness request to an AMF network element when it is determined that the user equipment allows positioning awareness according to the target privacy configuration data, and receive the perception information sent by the AMF network element, and generate a perception intention in response to the perception information, and the perception information is generated according to the perception privacy indication fed back by the user equipment after the AMF network element sends a notification call information to the user equipment according to the positioning awareness request.

For example, in this embodiment, the GMLC determines the identifier corresponding to the UE that needs to perform positioning perception through a positioning perception request, wherein the identifier can be the GPSI (Generic Public Subscription Identifier) or SUPI (Subscription Permanent Identifier) corresponding to the UE. GPSI sends the identifier to the UDM (Unified Data Management) network element, and the UDM network element determines the target privacy configuration data corresponding to the UE from the preset privacy configuration data based on the identifier. It is worth mentioning that the UDM is configured with preset privacy configuration data corresponding to each UE, which is used to determine the perception intention of each UE and establish a mapping relationship between the corresponding identifier of each UE and the corresponding preset privacy configuration data. The target privacy configuration data of the UE can be determined according to the identifier corresponding to the UE. For example, the following preset privacy configuration data can be configured in the UDM:

The UE's perception willingness is preliminarily determined through privacy-aware indication data, call/session-independent data, and PLMN (Public Land Mobile Network) operator category data. Among them, different UEs correspond to different target privacy configuration data. Each type of privacy configuration data includes necessary items and optional items, which can be configured according to the actual situation of the UE. Necessary items are configured in the privacy-aware indication data and call/session-independent data to determine the UE's perception willingness. If it is determined that the UE is not allowed to be perceived based on the necessary items, there is no need to determine other optional items, and the UDM returns the corresponding perception rejection request to the GMLC. In the preset privacy configuration data, a preliminary judgment is made on the perception request corresponding to the UE. When the necessary items are met, the UE's perception willingness is determined based on the optional items. For example, the target privacy configuration data corresponding to the UE is: privacy awareness indication-allowed perception, privacy awareness indication-valid time 10:00-11:00, call/session-independent class-any SAF network element that is not in the preset SAF network element, or other SAF network elements identified as call/session-independent classes, are allowed to be perceived. The UDM feeds back the target privacy configuration data to the GMLC. When the GMLC determines based on the analysis that the necessary item is allowed perception, it makes a judgment on the optional option privacy awareness indication-valid time 10:00-11:00. If the positioning perception request satisfies the optional option, it is determined that the UE is allowed to perform preliminary positioning perception. It is worth mentioning that there are optional items in the preset privacy configuration data that cannot be used to determine whether the UE is allowed to be positioned based on the relevant information in the current positioning perception request. For example, the target privacy configuration data fed back by UDM to GMLC is: privacy perception indication-allowed perception, call/session-independent class-any SAF network element that is not in the preset SAF network element, or other SAF network elements identified as call/session-independent class, allowed to be perceived, call/session-independent class-area where perception is allowed. After GMLC verifies the necessary items to determine that perception is allowed, it verifies the optional item. The optional item needs to obtain the UE's current service area through the AMF network element, and then verify the UE's perception intention. Therefore, when GMLC verifies the target privacy configuration data fed back by UDM, if there is no privacy configuration data that does not allow positioning perception, GMLC will send the positioning perception request to the AMF network element.

After receiving the location awareness request, the AMF network element sends a notification call information to the UE according to the location awareness request. The notification call information may include the type information of the SAF network element, the type information of the awareness request end, the service type information and the required service quality information, etc. The UE determines whether to allow the location awareness request according to the notification call information, and indicates the UE's awareness intention to the AMF network element through the awareness privacy indication information. For example, the notification call information may include a location awareness option, and the location awareness option includes allowing location awareness and not allowing location awareness. After receiving the notification call information, the UE displays the location awareness option in the UE, and in response to the user corresponding to the UE, the UE generates the UE's awareness privacy indication for the selection operation of the location awareness option, and the awareness privacy indication is fed back to the AMF network element. The AMF network element generates the awareness intention according to the awareness privacy indication and sends it to the GMLC. For example, after receiving the awareness privacy indication, the AMF network element determines whether the UE allows location awareness. When the UE allows location awareness, the UE is positioned by the corresponding positioning device to generate the UE's location information, and the UE's awareness intention is generated according to the location information and the awareness privacy indication and sent to the GMLC.

In step S103, in response to the perception willingness fed back by the GMLC, the perception willingness is sent to the perception requesting end.

For example, in this embodiment, when the SAF network element is an LCS client, after the GMLC receives the perception intention sent by the AMF network element, it sends the perception intention to the SAF network element, and the SAF network element feeds back the perception intention to the perception request end.

Optionally, the above steps, in response to the perception willingness fed back by the GMLC, send the perception willingness to the perception requesting end, including:

In response to the sensing willingness fed back by the GMLC through the NEF, the sensing willingness is sent to the sensing requesting end.

For example, in this embodiment, the SAF network element acts as the AF. After the GMLC receives the perception intention sent by the AMF network element, it sends the perception intention to the AF. The AF sends the UE's perception intention to the SAF network element, and the SAF network element feeds back the perception intention to the perception request end.

Through the above scheme, the SAF network element is applied as the LCS client or AF to receive the positioning perception intention of the perception request end, and obtain the UE's perception intention based on the LCS service architecture and feed it back to the perception request end, so that the perception request end can provide positioning perception services to the UE according to the UE's perception intention.

FIG3 is a flow chart of a positioning perception method according to an exemplary embodiment. As shown in FIG3 , the method is applied to GMLC, and the method includes the following steps.

In step S201, a positioning awareness request sent by a SAF network element is received, where the positioning awareness request is used to perceive attribute information of a user equipment.

For example, the way in which the GMLC receives the positioning perception request in this embodiment is the same as that in the above step S102, and the above step S102 can be referred to and will not be repeated.

For example, the definition of the attribute information in this embodiment is the same as that in the above step S101, and the above step S101 can be referred to and will not be described in detail.

In step S202, when the user equipment allows location awareness, a location awareness request is sent to the AMF network element.

For example, in this embodiment, the way in which GMLC sends the positioning awareness request to the AMF network element is the same as in the above step S102, and the above step S102 can be referred to and will not be repeated.

In step S203, the perception information sent by the AMF network element is received.

For example, the manner in which the GMLC receives the perception information in this embodiment is the same as that in the above step S102, and reference may be made to the above step S102, which will not be described in detail.

In step S204, the perception intention of the user equipment is generated according to the perception information.

For example, the method in which the GMLC generates the perceived willingness in this embodiment is the same as that in the above step S102, and the above step S102 can be referred to and will not be repeated.

In step S205, the perception intention is sent to the perception request end.

For example, in this embodiment, after the GMLC generates the UE's perception intention through the perception information, the perception intention can be sent to the perception request end through the SAF network element.

Optionally, in one implementation, the above step S205 includes:

When it is determined that the user equipment allows perception according to the perception intention, a location service response is sent to the perception request end through the SAF network element.

If it is determined according to the perception willingness that the user equipment does not allow perception, perception rejection information of the user equipment is generated.

The perception rejection information is sent to the perception request end through the SAF network element.

For example, in this embodiment, after the GMLC receives the perception information sent by the AMF network element, it generates the perception intention corresponding to the UE, and parses the perception intention to determine whether the UE allows the perception request end to perform positioning perception. When it is determined through the perception intention that the UE is allowed to be perceived, the UE's location information is sent to the perception request end through the SAF network element; when it is determined through the perception intention that the UE is not allowed to be perceived, the UE's perception rejection information is generated, and the perception rejection information is sent to the perception request end through the SAF network element.

Through the above method, GMLC is applied to determine the positioning perception request. When it is determined that the UE runs positioning perception, the positioning perception request is sent to the AMF network element, and based on the perception information fed back by the AMF network element, the UE's perception willingness is generated and sent to the perception request end. The perception request end can provide positioning perception services to the UE according to the UE's perception willingness.

FIG. 4 is a flow chart of a positioning awareness method according to an exemplary embodiment. As shown in FIG. 4 , the positioning awareness method is applied to GMLC and includes the following steps.

In step S301, a positioning awareness request sent by a SAF network element is received, where the positioning awareness request is used to perceive attribute information of a user equipment.

Optionally, in an implementation manner, when the user equipment allows location awareness, sending the location awareness request to the AMF network element includes:

In step S302, in response to the location awareness request, an identifier of the user equipment is determined.

For example, in this embodiment, after the GMLC receives the positioning awareness request sent by the SAF network element, it parses the positioning awareness request to determine the identifier of the UE.

Optionally, in another implementation, the above step of determining an identifier of the user equipment in response to the location awareness request includes:

According to the location awareness request, the associated data of the user device is obtained.

Based on the association data, an identifier of the user equipment is determined.

For example, in this embodiment, the GMLC can determine the associated data of the UE based on the positioning awareness request. The associated data can be the subscription data of the UE or other data provided by the SAF network element. The GMLC can derive the identifier of the UE from the associated data.

Optionally, in another implementation, the location awareness request includes a predetermined awareness time, and the above steps of determining the identifier of the user equipment in response to the location awareness request include:

When the current time reaches the predetermined perception time, the identifier of the user equipment is determined according to the positioning perception request.

For example, in this embodiment, GMLC parses the received positioning perception request to determine the scheduled perception time. The perception request end requests the attribute information of the UE at a specific time in the future based on the scheduled perception time in the positioning perception request. The GMLC makes a judgment based on the scheduled perception time. When the current time reaches the scheduled perception time, the UE identifier is determined based on the positioning perception request.

Determine a target number of user devices based on the location awareness request;

In case the target quantity is less than or equal to the perceived quantity threshold, an identifier of the user equipment is determined.

For example, in this embodiment, the perception request end can request attribute information of multiple UEs in the same positioning perception request. When the positioning perception request includes multiple UEs, GMLC parses the positioning perception request to determine the number of UEs in the positioning perception request, and judges the number of UEs. If the number of UEs is less than or equal to the perception number threshold, the identifier of each UE is determined through GMLC.

Optionally, in another real-time manner, the method further comprises:

In a case where the target quantity is greater than the sensing quantity threshold, sensing rejection information of the user equipment is generated.

For example, in this embodiment, GMLC determines the number of UEs in the positioning perception request. When the number of UEs is greater than the perception number threshold, it generates perception rejection information for the UE and sends the perception rejection information to the perception request end through the SAF network element to reject the positioning perception request of the perception request end.

Based on the location perception request, the SAF network element's location service is authorized and verified.

In case the location service authorization of the SAF network element is successful, an identifier of the user equipment is determined.

For example, in this embodiment, the positioning awareness request includes the identity information of the SAF network element. After receiving the positioning awareness request from the SAF network element, the GMLC performs authorization verification on the positioning service of the SAF network element. For example, there is a white list in the GMLC that is pre-authorized to perform positioning services, and the white list includes multiple SAF network elements. After receiving the positioning awareness request sent by the SAF network element, the identity information of the SAF network element is verified. If the identity information of the SAF network element exists in the white list, the positioning service of the SAF network element is authorized, and the UE identifier is determined based on the positioning awareness request sent by the SAF network element.

Optionally, in another implementation manner, the location awareness request includes service identification information, and the above steps perform authorization verification on the location service of the SAF network element according to the location awareness request, including:

When the service identification information matches the preset service identification information, the SAF network element is authorized to apply the positioning service.

In the case where the service identification information does not match the preset service identification information, the SAF network element application positioning service is rejected.

For example, in this embodiment, the GMLC is configured with preset service identification information, and the preset service identification information is used to record the service identification information of the authorized SAF network element. The service identification information of the SAF network element is determined by parsing the positioning awareness request, and the service identification information is compared with the preset service identification information. When the service identification information matches the preset service identification information, the SAF network element is authorized to apply the positioning service. When the service identification information does not match the preset service identification information, the SAF network element is denied to apply the positioning service.

Optionally, in another embodiment, the above method further includes:

In case the location service authorization of the SAF network element fails, perception rejection information of the user equipment is generated.

For example, in this embodiment, the GMLC performs authorization verification on the positioning perception request sent by the SAF network element. When the positioning perception request of the SAF network element does not meet the authorization conditions, it is determined that the positioning service authorization of the SAF network element has failed, and the SAF network element generates UE-based perception rejection information, and sends the perception rejection information to the perception request end through the SAF network element. For example, the perception rejection information may include the reason why the positioning perception request is rejected.

In step S303, the identifier is sent to the UDM network element.

For example, in this embodiment, after the GMLC determines the identifier of the UE through the above steps, it sends the identifier to the corresponding UDM network element.

In step S304, target privacy configuration data corresponding to the user equipment determined by the UDM network element from preset privacy configuration data according to the identifier is received.

For example, in this embodiment, the UDM network element determines the target privacy configuration data corresponding to the identifier from the preset privacy configuration data based on the identifier, wherein the definition of the preset privacy configuration data in the UDM is the same as that in the above step S102, and can refer to the above step S102 and will not be repeated.

In step S305, when it is determined according to the target privacy configuration data that the user equipment allows location awareness, a location awareness request is sent to the AMF network element.

For example, the UDM network element sends the target privacy configuration data to the GMLC, and the GMLC makes a judgment on the target privacy configuration data. When it is determined that the UE allows positioning awareness based on the target privacy configuration data, the positioning awareness request is sent to the AMF network element corresponding to the UE. The method of determining whether the UE allows positioning awareness is the same as that in the above step S102, and the above step S102 can be referred to and will not be repeated.

Optionally, in another implementation manner, in the above step S305, when it is determined according to the target privacy configuration data that the user equipment allows location awareness, sending the location awareness request to the AMF network element includes:

When it is determined according to the target privacy configuration data that the user equipment allows location awareness, the network address of the AMF network element currently served by the user equipment is determined.

When the network address is within the preset service range of GMLC, the positioning awareness request is sent to the AMF network element.

For example, in this embodiment, GMLC makes a preliminary judgment on the UE's perception willingness through the target privacy configuration data. When it is determined that the UE allows positioning perception, the network address of the AMF network element currently serving the UE is determined according to the UE identifier, and the network address is compared with the preset service range of the GMLC. When the AMF network element is within the preset service range of the GMLC, the positioning perception request is sent to the AMF network element.

Optionally, in another embodiment, the above method further includes:

When the network address is not within the preset service range, perception rejection information of the user equipment is generated.

For example, in this embodiment, the GMLC compares the network address of the AMF network element currently serving the UE with the preset service range of the GMLC to determine whether the AMF network element is within the preset service range of the GMLC. If the network address is no longer within the preset service range, the UE's perception rejection information is generated, and the perception rejection information is sent to the perception request end through the SAF network element. For example, the perception rejection information includes the reason for the rejection of the positioning perception request.

In step S306, the perception information sent by the AMF network element is received.

In step S307, the perception intention of the user equipment is generated according to the perception information.

In step S308, the perception intention is sent to the perception request end.

Through the above method, GMLC is applied to determine the positioning perception request. When it is determined that the UE allows positioning perception, the positioning perception request is sent to the AMF network element, and based on the perception information fed back by the AMF network element, the UE's perception willingness is generated and sent to the perception request end. The perception request end can provide positioning perception services to the UE according to the UE's perception willingness.

FIG5 is a flow chart of a positioning perception method according to an exemplary embodiment. As shown in FIG5 , the method is applied in a GMLC, which is a local mobile positioning center HGMLC. The method includes the following steps.

In step S401, a positioning awareness request sent by a SAF network element is received, where the positioning awareness request is used to perceive attribute information of a user equipment.

For example, in this embodiment, the UE in the positioning awareness request is in roaming state, the corresponding HGMLC is the GMLC of the UE registration location, the mobile positioning center gateway currently providing services for the UE is VGMLC (Visit Gateway Mobile Location Centre), and the positioning awareness request sent by the SAF network element is received through the HGMLC. The method of receiving the positioning awareness request through the HGMLC is the same as that in the above step S201, and the above step S201 can be referred to and will not be repeated.

Optionally, in one implementation, the step of sending a positioning awareness request to an AMF network element when the user equipment allows positioning awareness includes:

In step S402, the service network address of the VGMLC sent by the UDM network element is received.

For example, in this embodiment, after HGMLC parses the positioning awareness request, it obtains the UE identifier and sends the identifier to the UDM network element, determines the service network address of the VGMLC corresponding to the UE through the UDM network element, and sends the service network address and the positioning awareness request to the HGMLC.

In step S403, the positioning awareness request is sent to the VGMLC according to the service network address, so that the positioning awareness request is sent to the AMF network element through the VGMLC.

For example, in this embodiment, after HGMLC determines the service network address of VGMLC, it sends a positioning awareness request to VGMLC. The way in which VGLMLC sends the positioning awareness request to the AMF network element is the same as in the above step S202. You can refer to the above step S202 and will not repeat it again.

Optionally, in another embodiment, the method further comprises:

When the service network address is the same as the registered network address of HGMLC, the positioning awareness request is sent to the AMF network element.

For example, in this embodiment, when the HGMLC does not receive the VGMLC address from the UDM, or the received VGMLC address is the same as the HGMLC address, or the HPLMN and VPLMN operators agree, the HGMLC can send a positioning awareness request to the currently serving AMF.

Optionally, in another implementation, the above step S403 includes:

A positioning awareness request is sent to VGMLC, where the positioning awareness request is used to instruct VGMLC to obtain the registered network address of HGMLC according to the positioning awareness request, and to send the positioning awareness request to the AMF network element when the registered network address matches the preset authorized address of VGMLC; wherein the positioning awareness request includes at least one of service quality information, perception time information or service type information.

For example, in this embodiment, when the UE is in roaming state, after HGMLC sends a positioning perception request to VGMLC, VGMLC obtains the registered network address of HGMLC according to the positioning perception request, and compares the registered network address with the preset authorized address of VGMLC. When the registered network address is the preset authorized address of VGMLC, VGMLC sends the positioning perception request to the corresponding AMF network element. For example, the positioning perception request may include QoS (Quality of Service) information, perception time information and service type information.

Optionally, in another embodiment, the method further includes:

The location awareness request is sent to the VGMLC, and the location awareness request is used to instruct the VGMLC to obtain the registered network address of the HGMLC according to the location awareness request, and generate awareness rejection information of the user equipment when the registered network address does not match the preset authorized address of the VGMLC.

For example, in this embodiment, after HGMLC sends a positioning perception request to VGMLC, VGMLC obtains the registered network address of HGMLC based on the positioning perception request, and compares the registered network address with the preset authorized address of VGMLC. When the registered network address does not match the preset authorized address of VGMLC, it generates UE perception rejection information and sends the perception rejection information to the perception request end through the SAF network element.

In step S404, the perception information sent by the AMF network element is received.

For example, the manner in which the HGMLC receives the perception information in this embodiment is the same as that in the above step S203, and reference may be made to the above step S203, which will not be described in detail.

In step S405, the perception intention of the user equipment is generated according to the perception information.

In step S406, the perception intention is sent to the perception request end.

Through the above method, when the UE is in roaming state, HGMLC is used to determine the location perception request. When it is determined that the UE runs location perception, the location perception request is sent to VGMLC, which sends the location perception request to the AMF network element, and generates the UE's perception intention based on the perception information fed back by the AMF network element and sends it to the perception request end, so that the perception request end can provide the UE with location perception service according to the UE's perception intention.

FIG6 is a flow chart of a positioning perception method according to an exemplary embodiment. As shown in FIG6 , the method is applied to GMLC, and the method includes the following steps.

In step S501, a positioning awareness request sent by a SAF network element is received, where the positioning awareness request is used to perceive attribute information of a user equipment.

For example, the method of receiving the positioning perception request in this embodiment is the same as that in the above step S301, and can refer to the above step S301 and will not be repeated here.

In step S502, in response to the location awareness request, an identifier of the user equipment is determined.

For example, the method of determining the identifier in this embodiment is the same as that in the above step S302, and can refer to the above step S302, which will not be repeated here.

In step S503, the identifier is sent to the UDM network element.

For example, the method of sending the identifier in this embodiment is the same as that in the above step S303, and can refer to the above step S303, which will not be repeated here.

In step S504, target privacy configuration data corresponding to the user equipment determined by the UDM network element from preset privacy configuration data according to the identifier is received.

For example, the method of receiving the target privacy configuration data in this embodiment is the same as that in the above step S304, and can refer to the above step S304, which will not be repeated here.

In one implementation, when it is determined according to the target privacy configuration data that the user equipment allows location awareness, the step of sending a location awareness request to the AMF network element includes the following steps S505 and S506:

In step S505, a privacy check is performed on the user device according to the target privacy configuration data to generate a privacy check result.

In step S506, when it is determined according to the privacy check result that the user equipment needs to be verified based on the current location, a positioning awareness request is sent to the AMF network element. The positioning awareness request is used to indicate the awareness instruction, and the positioning awareness request includes the type information of the SAF network element.

For example, in this embodiment, when the GMLC parses the target privacy configuration data corresponding to the UE and determines that the UE needs to perform a privacy check, it generates a privacy check result based on the target privacy configuration data, and when it determines that the UE needs to be verified based on the current location based on the privacy check result, it sends a positioning awareness request to the AMF network element, wherein the positioning awareness request is used to instruct the AMF network element that "it can be perceived without notification". For example, the positioning awareness request includes type information of the SAF network element.

In step S507, the perception information sent by the AMF network element is received.

For example, the method of receiving perception information in this embodiment is the same as that in the above step S306, and can refer to the above step S306, which will not be repeated here.

In step S509, the perception intention is sent to the perception request end.

For example, the method of sending the perceived willingness in this embodiment is the same as that in the above step S308, and can refer to the above step 308, which will not be repeated here.

FIG7 is a flow chart of a positioning awareness method according to an exemplary embodiment. As shown in FIG7 , the method is applied to an AMF network element, and the method includes the following steps.

In step S601, in response to a positioning awareness request sent by the GMLC, a notification call information is sent to the user equipment, where the positioning awareness request is used to perceive attribute information of the user equipment.

For example, in this embodiment, the way in which the AMF network element sends notification call information to the UE based on the positioning awareness request sent by the GMLC is the same as in the above step S102. The above step S102 can be referred to and will not be repeated. The positioning awareness request is sent by the GMLC when the user equipment allows positioning awareness. The positioning awareness request is sent by the SAF network element to the GMLC. The positioning awareness request is used to perceive the attribute information of the user equipment.

Optionally, in one implementation, the above step S601 includes:

In response to the positioning awareness request sent by GMLC, a notification call information is sent to the user equipment. The positioning awareness request is sent by GMLC when it determines that the user equipment allows positioning awareness according to the target privacy configuration data corresponding to the user equipment. The target privacy configuration data is determined by the UDM network element from the preset privacy configuration data according to the identifier of the user equipment sent by GMLC. The identifier of the user equipment is determined by GMLC after receiving the positioning awareness request sent by the SAF network element.

For example, in this embodiment, after the GMLC receives the positioning perception request sent by the SAF network element, it parses the positioning perception request to determine the identifier of the UE, and sends the identifier to the UDM network element. The UDM network element determines the target privacy configuration data corresponding to the UE from the preset privacy configuration data based on the identifier, and sends the target privacy configuration data to the GMLC. The GMLC determines the UE's perception willingness based on the target privacy configuration data. When it is determined that the UE allows positioning perception, the positioning perception request is sent to the AMF network element. The AMF network element sends a notification call information to the UE based on the positioning perception request.

Optionally, in another implementation, the above step S601 includes:

Determine the connection status of the user device based on the location awareness request.

When the user equipment is in an idle state, a signaling connection with the user equipment is established through a preset network triggering service request process.

In response to the signaling connection being successful, a notification calling message is sent to the user equipment.

For example, in this embodiment, after the AMF network element receives the positioning perception request sent by the GMLC, it confirms the connection status of the UE. If the UE is in the CM IDLE state (connection management-idle state), the AMF starts the network trigger service request process to establish a signaling connection with the UE; if the UE is in the CM-Connected state (connection management-connected state), the signaling connection with the UE is directly established. After the UE's signaling connection is successful, the AMF network element sends a notification call information to the UE.

Optionally, in another implementation, the above step S601 includes:

Determine privacy check indication information of a user device based on the location awareness request.

When it is determined according to the privacy check indication information that the user equipment needs to be notified for privacy verification, a notification call information is sent to the user equipment, and the notification call information includes the identity information of the SAF network element, the identity information of the perception request end, and the service type information.

For example, in this embodiment, the privacy check configuration related to the UE is received from the UDM through the above steps, and the privacy check related action indication information is obtained according to the privacy check configuration. According to the indication information, it is determined that the UE needs to be notified for privacy verification, and the UE supports positioning awareness, then a notification call message is sent to the UE through AMF, wherein the notification call message includes the identity information of the SAF, the ID information of the perception request end, the service type, and whether a privacy verification option is required. It is worth mentioning that the perception intention of the UE is obtained through the notification call message, and the UE expresses the positioning perception intention of the UE by choosing whether privacy verification is required.

In step S602, perception information is generated according to the perceived privacy indication fed back by the user equipment.

For example, the method of generating perception information in this embodiment is the same as that in the above step S102, and can refer to the above step S102, which will not be repeated here.

Optionally, the perceived privacy indication includes a perceived time.

For example, in this embodiment, the perception privacy indication fed back by the UE includes the perception time, which is used to feed back the perception time during which the UE is allowed to perform positioning perception.

Optionally, in another implementation, the above step S601 includes:

When it is determined according to the privacy awareness indication that the user equipment needs to perform privacy verification, the notification result fed back by the user equipment is monitored, and the notification result is used to instruct the user equipment to allow the location awareness request or reject the location awareness request.

Generate perception information based on the notification result fed back by the user device.

For example, in this embodiment, the AMF network element sends a notification call information to the UE, and in the UE, when it is determined that the UE needs to perform privacy verification based on the perceived privacy indication fed back by the UE in response to the positioning perception request, the AMF network element monitors the notification result fed back by the UE and waits for the user to grant or deny permission based on the privacy verification. When the UE returns the notification result to the AMF, indicating whether to allow or deny the current positioning perception request, the AMF network element generates perception information based on the notification result fed back by the UE.

Optionally, in another embodiment, the method further comprises:

If no notification result is received from the user equipment within a preset time, a sensed no response message is generated.

For example, in this embodiment, if the UE does not feedback a response after a predetermined time period after the AMF network element sends a notification call message, the AMF network element will infer a "no response" condition, and the AMF network element returns an error response to the GMLC. For example, if the UE is in a roaming situation, the AMF returns an error response to the VGMLC, and if privacy verification is requested and the UE refuses permission or the VGMLC does not receive a response indicating prohibition of the positioning request from the HGMLC, the VGMLC returns an error response to the HGMLC. For example, the notification result fed back by the UE can also indicate the perception privacy indication setting of subsequent positioning perception requests, that is, whether the UE allows or prohibits subsequent positioning perception requests.

Optionally, in another implementation, the above step S601 includes:

The perceived privacy indication is sent to the location management function LMF network element. The perceived privacy indication is used to instruct the LMF network element to locate the user equipment and feedback the location information of the user equipment.

Based on the location information, perception information is generated.

For example, in this embodiment, after the AMF network element receives the perception privacy indication fed back by the UE, it parses the perception privacy indication, and when it determines that the perception privacy indication is to allow perception, it sends the perception privacy indication to the LMF (Location Management Function) network element, and locates the UE through the LMF network element, and feeds back the UE's location information. The AMF network element generates corresponding perception information based on the UE's location information.

Optionally, in another implementation, the above step sends the perceived privacy indication to the location management function LMF network element, and the perceived privacy indication is used to instruct the LMF network element to locate the user equipment and feedback the location information of the user equipment, including:

The perceived privacy indication is sent to the LMF network element, and the perceived privacy indication is used to instruct the LMF network element to determine the target LMF module according to the perceived privacy indication, and locate the user equipment through the target LMF module.

For example, in this embodiment, after the perceived privacy indication is fed back by the UE, the perceived privacy indication can be sent to the LMF network element through the AMF network element. The LMF network element parses the perceived privacy indication to determine the target LMF module that meets the perceived privacy indication, and locates the UE according to the target LMF module.

In step S603, the perception information is sent to the GMLC, where the perception information is used to instruct the GMLC to generate the perception intention of the user equipment according to the perception information, and send the perception intention to the perception requesting end.

For example, the method of sending perception information in this embodiment is the same as that in the above step S102, and can refer to the above step S102, which will not be repeated here.

Through the above method, the AMF network element is used to receive the positioning perception request sent by the GMLC, and a notification call information is sent to the UE according to the positioning perception request, so that the UE can feedback the perception privacy indication, and the perception information is generated according to the perception privacy indication and sent to the GMLC, so that the GMLC sends the perception information to the perception request end through the SAF network element, so that the perception request end can provide the UE with positioning perception service according to the UE's perception intention.

FIG8 is a flow chart of a positioning awareness method according to an exemplary embodiment. As shown in FIG8 , the method is applied to an AMF network element, and the method includes the following steps.

In step S701, in response to a positioning awareness request sent by the GMLC, a notification call information is sent to the user equipment, where the positioning awareness request is used to perceive attribute information of the user equipment.

For example, the method of sending notification call information in this embodiment is the same as that in the above step S601, and can refer to the above step S601 and will not be repeated. The positioning perception request is sent by GMLC when the user equipment allows positioning perception. The positioning perception request is sent by the SAF network element to GMLC, and the positioning perception request is used to perceive the attribute information of the user equipment.

In step S702, perception information is generated according to the perceived privacy indication fed back by the user equipment.

For example, the method of generating perception information in this embodiment is the same as that in the above step S601, and can refer to the above step S602, which will not be repeated.

In step S703, the perception information is sent to the GMLC, where the perception information is used to instruct the GMLC to generate the perception intention of the user equipment according to the perception information, and send the perception intention to the perception requesting end.

For example, the method of sending perception information in this embodiment is the same as that in the above step S603, and can refer to the above step S603, which will not be repeated here.

In step S704, the perceived privacy indication information of the user equipment is determined according to the notification result.

For example, after determining the notification result of the UE's feedback through the above-mentioned privacy verification, the UE's perceived privacy indication information is determined according to the notification result, and the perceived privacy indication information is the UE's latest perceived privacy indication, and the perceived privacy indication information is stored in the AMF network element.

In step S705, in response to receiving the target location awareness request from the user equipment again, the awareness information is generated according to the awareness privacy indication information.

For example, in this embodiment, when the AMF network element receives the positioning awareness request of the UE again, it can judge the positioning awareness request based on the awareness privacy indication information and generate corresponding awareness information.

Optionally, in one implementation, after the above step S705, the method further includes:

The perceived privacy indication information is sent to the UDM network element, and the perceived privacy indication information is used to instruct the UDM network element to store the perceived privacy indication information as a data subset of the subscription data in the user data registration module UDR.

For example, in this embodiment, after determining the perceived privacy indication information of the UE through the above steps, the AMF network element sends the perceived privacy indication information to the UDM network element, so that the UDM network element updates the target privacy configuration information of the UE. The UDM network element uses the perceived privacy indication information as a data subset of the subscription data and stores the perceived privacy indication information in the UDR (User Data Repository) corresponding to the UE.

FIG9 is a flow chart of a positioning awareness method according to an exemplary embodiment. As shown in FIG9 , the method is applied to an AMF network element, and the method includes the following steps.

In step S801, in response to a positioning awareness request sent by the GMLC, a notification call information is sent to the user equipment, where the positioning awareness request is used to perceive attribute information of the user equipment.

In step S802, perception information is generated according to the perceived privacy indication fed back by the user equipment.

In one implementation, the above steps send the perception information to the GMLC, the perception information is used to instruct the GMLC to generate the perception intention of the user equipment according to the perception information, and send the perception intention to the perception requesting end, including the following steps S803, S804, S805 and S806.

In step S803, the perception information is sent to the GMLC, where the perception information is used to instruct the GMLC to feedback a privacy check request when it is determined that the user equipment needs to be privacy checked according to the target privacy configuration data and the perception information.

For example, in this embodiment, the AMF network element receives the perception privacy indication fed back by the UE, generates perception information, and sends it to the GMLC. The GMLC determines whether the UE needs to perform further privacy checks based on the perception information and the target privacy configuration data. When it is determined that the UE does not need to perform further privacy checks, the GMLC generates a perception intention based on the perception information and sends it to the perception request end through the SAF network element. When the GMLC determines that the UE needs to perform further privacy checks based on the perception information and the target privacy configuration data, it generates a privacy check request and feeds it back to the AMF network element.

In step S804, in response to the privacy check request sent by the GMLC, target notification calling information is sent to the user equipment.

For example, in this embodiment, the way in which the AMF network element sends notification call information to the UE after receiving the privacy check request is the same as in the above step S601, and can refer to the above step S601 and will not be repeated.

In step S805, target awareness information is generated according to the target awareness privacy indication fed back by the user equipment.

For example, the way in which the AMF network element generates target perception information in this embodiment is the same as in the above step S601, and can refer to the above step S601 and will not be repeated here.

In step S806, the target perception information is sent to the GMLC, where the target perception information is used to instruct the GMLC to generate a target perception intention of the user equipment according to the target perception information and send it to the perception requesting end.

For example, in this embodiment, the AMF network element sends the target perception information to the GMLC. The GMLC determines again whether the UE needs to perform further privacy checks based on the target perception information and the target privacy configuration information. When the GMLC determines that the UE does not need to perform further privacy checks, it generates a perception intention based on the target perception information and sends it to the perception request end through the AMF network element; when the GMLC determines that the UE needs to perform further privacy checks, the above steps S804-S806 are repeated until the GMLC determines that the UE no longer needs to perform further privacy checks based on the perception information and the target privacy configuration data. The GMLC generates the UE's perception intention based on the perception information and sends it to the perception request end through the SAF.

Optionally, the above step S806 includes:

The target perception information is sent to the GMLC, where the target perception information is used to instruct the GMLC to generate a verification result of the user equipment according to the target perception information.

The target perception intention of the user device is generated according to the target perception information and the verification result.

For example, in this embodiment, after the AMF network element sends the target perception information to the GMLC, the GMLC notifies and verifies the UE based on the target perception information, and generates a verification result for the UE. When it is determined based on the verification result that the UE does not need to perform further privacy checks, the UE's target perception intention is generated based on the target perception information and the verification result.

Optionally, in another implementation, the above step S806 includes:

The perception information is sent to the GMLC, and the perception information is used to instruct the GMLC to determine the target privacy check indication information of the user equipment according to the target privacy configuration data and the perception information, and to feedback the privacy check request when it is determined according to the target privacy check indication information that the user equipment needs to be notified for a privacy check.

For example, in this embodiment, the target privacy check indication information of the UE is determined based on the perception information and the privacy configuration data, and after determining that the UE needs to perform further privacy check based on the target privacy check indication information, the privacy check request is fed back to the AMF network element, so that the AMF network element sends privacy verification to the UE based on the privacy check request.

FIG10 is a flow chart of a positioning awareness method according to an exemplary embodiment. As shown in FIG10 , the method is applied to an AMF network element, and the method includes the following steps.

In step S901, in response to a positioning awareness request sent by the GMLC, a notification call information is sent to the user equipment, where the positioning awareness request is used to perceive attribute information of the user equipment.

In step S902, perception information is generated according to the perceived privacy indication fed back by the user equipment.

For example, the method of generating perception information in this embodiment is the same as that in the above step S602, and can refer to the above step S602, which will not be repeated here.

In one implementation, the step of sending the perception information to the GMLC, where the perception information is used to instruct the GMLC to generate the perception intention of the user equipment according to the perception information, and send the perception intention to the perception requesting end, includes step S903:

In step S903, the sensing information is sent to the visited mobile positioning center VGMLC, so that the sensing information is sent to the home mobile positioning center HGMLC through the VGMLC.

For example, in this embodiment, when the UE is in a roaming state, after the AMF generates the perception information of the UE, it sends the perception information to the VGMLC, and the perception information is sent to the HGMLC through the VGMLC. The HGMLC generates the UE's perception intention through the perception information and sends it to the perception request end through the SAF.

FIG. 11 is a flow chart of a positioning awareness method according to an exemplary embodiment. As shown in FIG. 11 , the method is applied to a UE, and the method includes the following steps.

In step S1001, the notification call information sent by the AMF network element is obtained. The notification call information is sent by the AMF network element when it receives a positioning perception request sent by the GMLC. The positioning perception request is used to perceive the attribute information of the user equipment.

For example, in this embodiment, the way in which the UE obtains the notification call information is the same as that in the above step S601, and the above step S601 can be referred to and will not be repeated.

Optionally, in one implementation, the above step S1001 includes:

Get the notification call information sent by the AMF network element. The notification call information is sent by the AMF network element when it receives the positioning awareness request sent by GMLC. The positioning awareness request is sent to the AMF network element by GMLC when it determines that the user equipment allows positioning awareness according to the target privacy configuration data corresponding to the user equipment. The target privacy configuration data is determined by the UDM network element from the preset privacy configuration data according to the identifier of the user equipment sent by GMLC. The identifier of the user equipment is determined by GMLC after receiving the positioning awareness request sent by the SAF network element.

For example, the method for acquiring the notification call information in this embodiment is the same as that in the above step S102, and can refer to the above step S102, which will not be repeated here.

In step S1002, in response to the user's selection result of notification call information, a perceived privacy indication is generated.

For example, the method of generating the privacy-aware indication in this embodiment is the same as that in the above step S601, and can refer to the above step S601, which will not be repeated here.

In step S1003, the perceived privacy indication is sent to the AMF network element, and the perceived privacy indication is used to indicate the perceived willingness of the user equipment.

For example, in this embodiment, a perception privacy indication is sent to generate perception information through the AMF network element, and the perception information is sent to the GMLC. The way in which the GMLC generates a perception intention through the perception information and sends it to the perception requesting end is the same as in the above step S601. The above step S601 can be referred to and will not be repeated.

Through the above method, the application UE obtains the notification call information sent by the AMF network element, and generates a perception privacy indication based on the user's selection result of the notification call information, and sends it to the AMF network element, so that the AMF network element generates perception information according to the perception privacy indication and sends it to the GMLC, and generates the UE's perception intention through the GMLC and sends it to the perception request end. Thereby, the perception request end can provide positioning perception services for the UE according to the UE's perception intention.

FIG. 12 is a flow chart of a positioning awareness method according to an exemplary embodiment. As shown in FIG. 12 , the method is applied to a UDM network element, and the method includes the following steps.

In step S1101, an identifier of a user equipment sent by the GMLC is received.

For example, the method of receiving the identifier in this embodiment is the same as that in the above step S102, and can refer to the above step S102, which will not be repeated here.

In step S1102, target privacy configuration data corresponding to the user equipment is determined from preset privacy configuration data according to the identifier.

For example, the method of determining the target privacy configuration data in this embodiment is the same as that in the above step S102, and can refer to the above step S102, which will not be repeated here.

In step S1103, the target privacy configuration data is sent to the GMLC.

For example, the method of sending the target privacy configuration data in this embodiment is the same as that in the above step S102, and can refer to the above step S102, which will not be repeated here.

Through the above method, UDM is applied to determine the target privacy configuration data of the UE, and the target privacy configuration data is sent to GMLC, so that when GMLC determines that the UE allows positioning perception based on the target privacy configuration data, it sends a positioning perception request to the AMF network element, and generates a perception intention based on the perception information fed back by the AMF network element and sends it to the perception request end, so that the perception request end can provide positioning perception services for the UE according to the perception intention of the UE.

13 is a block diagram of a positioning awareness system according to an exemplary embodiment, the system comprising: a perception application function SAF network element, a mobile positioning center gateway GMLC, a unified data management UDM network element, an access and mobility management function AMF network element and a user device.

The GMLC determines, in response to the location awareness request, an identifier of the user equipment, and sends the identifier to the UDM network element;

The AMF network element sends a notification call information to the user equipment in response to the location awareness request sent by the GMLC;

The user equipment generates a perceived privacy indication in response to the notification call information according to the selection result of the user on the notification call information, and sends the perceived privacy indication to the AMF network element;

The AMF network element generates perception information according to the perception privacy indication fed back by the user equipment, and sends the perception information to the GMLC;

The GMLC generates a perception intention of the user equipment according to the perception information, and sends the perception intention to the perception request end through the SAF network element.

Optionally, in one implementation, FIG14 is a flowchart of a positioning perception method according to an exemplary embodiment, and the method is applied to the above-mentioned positioning perception system. As shown in FIG14 , the method includes the following steps.

1. When SAF acts as an LCS client, after receiving the positioning perception request sent by the perception request end through SAF, it identifies the GPSI (Generic Public Subscription Identifier) or SUPI (SUbscription Permanent Identifier) included in the positioning perception request, determines the UE for which the perception request end performs positioning perception, and sends the positioning perception request to the corresponding HGMLC for positioning perception according to the GPSI or SUPI. The positioning perception request is used to perceive the attribute information of the UE, and the attribute information may include location information, speed information, shape information, direction information, etc. For example, the positioning perception request may include the QoS (Quality of Service), supported GAD shapes and other attributes required for positioning perception. After the HGMLC determines the GPSI or SUPI corresponding to the UE through analysis according to the location awareness request, it makes an authorization decision on the SAF based on the LCS service of the UE. For example, the HGMLC can also determine the GPSI or SUPI of the UE from the subscription data or other data provided by the SAF, and may derive the QoS required by the location-aware UE. When the SAF meets the authorization conditions, the SAF is authorized to use the LCS service. If the authorization fails, step 2-23 is skipped, and the HGMLC generates the perception rejection information of the UE, and the perception rejection information is fed back to the perception request end through the SAF, and the HGMLC responds to the SAF in step 24 that the service authorization fails. For example, the location awareness request can also carry the service identifier, service password and service scope information of the location awareness service. The HGMLC can verify whether the service identifier received in the location awareness request matches one of the service identifiers allowed by the SAF. If the service identifier does not match one of the service identifiers allowed by the SAF, the HGMLC will reject the location awareness of the SAF. Otherwise, the HGMLC can map the received service identifier to the corresponding service type to provide the UE with location awareness services.

It is worth mentioning that when the perception request end requests to obtain the current location information of the UE at a specific time in the future, the SAF parses the positioning perception request and includes the scheduled scheduled perception time in the positioning perception request sent to the HGMLC.

For example, if the positioning perception request contains a pseudonym of the UE, and the HGMLC cannot resolve the PMD (Physical Medium Department) address of the UE from the pseudonym, the HGMLC will self-name the UE to determine the GPSI or SUPI of the UE. If the HGMLC can resolve the PMD address of the UE from the pseudonym, the HGMLC will request the GPSI or SUPI of the UE from the associated PMD. If the HGMLC cannot obtain the GPSI or SUPI of the UE, the HGMLC will reject the positioning perception request, skip steps 2-23, and the HGMLC will generate the perception rejection information of the UE, and feedback the perception rejection information to the perception request end through the SAF, and the HGMLC will respond to the SAF in step 24 that the service authorization has failed.

1b-1 When SAF, as AF, receives a positioning awareness request sent by the awareness requester, SAF sends the Nnef_EventExposure_Subscribe instruction to NEF, where the positioning awareness request includes the QoS (Quality of Service), supported GAD shapes and other attributes required for positioning awareness.

1b-2 The NEF identifies the corresponding HGMLC based on the QoS attributes received from the location awareness request, calls the Ngmlc_Location_ProvideLocation instruction to the HGMLC, and sends a location awareness request to the HGMLC to request location awareness service, wherein the location awareness request includes attribute information received from the SAF, and the attribute information is the attribute information of the UE that the awareness requesting end requests to perceive.

It is worth mentioning that if the positioning perception request sent by the perception request end includes multiple UEs, when NEF or HGMLC receives the positioning perception request sent by SAF through the Nnef_EventExposure_Subscribe instruction or the positioning perception request instruction, it determines the number of UEs in the positioning perception request to determine whether the number of UEs is equal to or less than the maximum number of UEs of SAF. If the maximum number of UEs is exceeded, NEF or HGMLC will reject the Nnef_EventExposure_Subscribe instruction or the positioning perception request instruction, skip steps 2-23, and the HGMLC will generate the perception rejection information of the UE, and feedback the perception rejection information to the perception request end through SAF, and the HGMLC will respond to the SAF with a perception request error and the corresponding error cause in step 24.

2. After HGMLC receives the positioning perception request sent by SAF and verifies that the positioning perception request is authorized successfully, it calls the Nudm_SDM_Get instruction to the UDM of the UE to complete the contract service operation with UDM. UDM searches the preset privacy configuration data through the GPSI or SUPI of the UE to obtain the target privacy settings of the UE identified by the GPSI or SUPI. The definition of the preset privacy configuration data is the same as that in the above step S102 and will not be repeated here. UDM feeds back the target privacy settings to HGMLC. HGMLC parses the target privacy configuration to determine whether the UE is allowed to perform positioning perception. If positioning perception of the UE is not allowed, steps 3-23 are skipped, and HGMLC generates perception rejection information for the UE, and feeds back the perception rejection information to the perception request end through SAF. In step 24, HGMLC responds to SAF that the service authorization has failed.

3. HGMLC uses the GPSI or SUPI of the UE to call the Nudm_UECM_Get instruction to the UDM of the UE to call the retrieval service operation in the UDM. The UDM returns the network address of the UE corresponding to the current serving AMF and the address of the VGMLC (for UE in roaming situation). For example, if the positioning perception request is an immediate positioning request, the HGMLC determines the country code of the UE's current serving node address based on the network address of the UE's current serving AMF and the address of the VGMLC. If the HGMLC determines that the currently serving AMF or VGMLC is not within the service range of the HGMLC, the HGMLC returns an error message to the SAF, skips steps 3-23, and the HGMLC generates the perception rejection information of the UE, and feeds back the perception rejection information to the perception request end through the SAF. In step 24, the HGMLC responds to the SAF with a perception request error and the corresponding error cause.

4. When the UE is roaming, the HGMLC may receive the address of the VGMLC currently serving the UE and/or the network address of the AMF currently serving from the UDM in step 3. For example, the HGMLC may also use the NRF (NF Register Function) service in the HPLMN (Home Public Land Mobile Network) to select the VGMLC in the available VPLMN (Visited-PLMN) as the current serving VPLMN of the UE. Optionally, the VPLMN identifier currently serving the UE may also be determined based on the AMF address received in step 3. The HGMLC sends a location awareness request to the VGMLC by sending the Ngmlc_Location_ProvideLocation instruction to the VGMLC to invoke the location service operation.

It is worth mentioning that when HGMLC does not receive the VGMLC address from UDM, or the received VGMLC address is the same as the HGMLC address, or the HPLMN and VPLMN operators agree, this step is skipped, and HGMLC can send a positioning awareness request to the currently serving AMF. For example, HGMLC performs a privacy check on the UE based on the target privacy configuration data fed back by UDM. If the result of the privacy check indicates that verification based on the current location of the UE is required, HGMLC sends a positioning awareness request to VGMLC (in the case of roaming) or to AMF (in the case of non-roaming), indicating "no notification is required for perception". For example, HGMLC also provides SAF type information (including AF type and/or LCS client type) in the positioning awareness request.

5. When the UE is roaming, VGMLC first determines whether the country address corresponding to the positioning perception request from HGMLC and HPLMN is an authorized country address. If not, an error response is returned to HGMLC, and steps 3-23 are skipped. HGMLC generates the perception rejection information of the UE, and feeds back the perception rejection information to the perception request end through SAF. In step 24, HGMLC responds to SAF with a perception request error and the corresponding error cause. If the country address corresponding to the positioning perception request is a country address authorized by VGMLC, after VGMLC receives the positioning perception request sent by HGMLC, it calls the positioning perception service operation to AMF through the Namf_Location_ProvidePositioningInfo instruction to request the perception of the UE. For example, the service operation includes the UE's SUPI or GPSI, SAF type, and the required QoS information, scheduling perception time information, service type and other attributes received or determined in step 1.

6. Confirm the connection status of the UE through AMF. If the UE is in CM IDLE state (connection management-idle state), AMF starts the network trigger service request process to establish a signaling connection with the UE; if the UE is in CM-Connected state (connection management-connected state), it directly establishes a signaling connection with the UE.

7. Receive the privacy check configuration related to the UE from the UDM through the above steps, and obtain the privacy check related action indicator according to the privacy check configuration. According to the indicator, it is determined that the UE needs to be notified for privacy verification, and the UE supports positioning awareness, then send a notification call message to the UE through AMF, wherein the notification call message includes the identity information of the SAF, the ID information of the perception requester, the service type, and whether the privacy verification option is required. It is worth mentioning that the perception intention of the UE is obtained through the notification call message, and the UE expresses the positioning perception intention of the UE by choosing whether privacy verification is required.

8. In the UE, respond to the location awareness request. If privacy verification is required in the location awareness request, the AMF waits for the user to grant or deny permission based on the privacy verification. Then, the UE returns a notification result to the AMF, indicating whether privacy verification is requested and whether the current location awareness request is allowed or denied. If the UE does not respond after a predetermined time period after the AMF sends a notification call message, the AMF will infer the "no response" condition, skip steps 9-13, and the AMF returns an error response to the HGMLC. If the UE is in a roaming situation, the AMF returns an error response to the VGMLC. If privacy verification is requested and the UE refuses permission or the VGMLC does not receive a response indicating prohibition of the location request from the HGMLC, steps 10 to 13 are skipped, and the VGMLC returns an error response to the HGMLC. For example, the notification result fed back by the UE can also indicate the perceived privacy indication setting of subsequent location awareness requests, that is, whether the UE allows or prohibits subsequent location awareness requests.

9. Based on the notification result sent by the UE, the AMF calls the positioning service operation through the Nudm_ParameterProvision_Update instruction, and stores the sensed privacy indication information received from the UE in the UDM. The UDM can store the updated UE privacy setting information in the UDR as the "perceived privacy" data subset of the subscription data.

10. When the AMF determines that the UE is allowed to be sensed through the notification result sent by the UE, it sends an LMF selection instruction to the LMF. The LMF selects the LMF module that meets the UE's attributes according to the UE, and locates the UE based on the LMF module. For example, the AMF can indicate the service type to the LMF, and the LMF can also determine the UE's perception information based on the local coordinates and/or geographic coordinates.

11. AMF sends a Nlmf_Location_DetermineLocation command to LMF to request UE's perception information. For example, if a scheduled perception time is provided in step 5 above, the Nlmf_Location_DetermineLocation command includes the scheduled perception time.

12. In response to the positioning request sent by the AMF, the LMF sends a positioning perception request to the UE to perceive the attribute information of the UE. For example, when the LMF sends the positioning perception request to the UE, the LMF may include the scheduled perception time.

13. Based on the Nlmf_Location_DetermineLocation request instruction, LMF sends the acquired UE perception information to AMF.

14. When the UE is roaming, the AMF invokes a service operation based on the Namf_Location_ProvidePositioningInfo instruction to return the UE's current perception information to the VGMLC. For example, the service operation includes perception estimation data, UE age and perception accuracy data, and may include timestamp information about the perception method and perception estimation.

15. When the UE is roaming, the VGMLC forwards the UE's perception estimation data, the UE's age, the perception accuracy data, and the information of the perception method received in step 14 to the HGMLC. For non-roaming scenarios, the AMF invokes the service operation based on the Namf_Location_ProvidePositioningInfo instruction and returns the UE's current perception information to the HGMLC.

16. After receiving the perception information fed back by AMF or VGMLC, HGMLC determines whether the UE needs to perform further privacy checks based on the privacy check data corresponding to the UE's target privacy configuration data in step 2 and the perception information, so as to determine whether HGMLC can forward the perception information to SAF. When it is determined through the result of the privacy check that notification and verification are required based on the current location of the UE, a verification notification is sent to AMF for verification. For example, when it is determined through the UE's target privacy configuration data that the UE has defined different privacy settings for different geographic locations, the UE needs to perform further privacy checks. When no additional privacy check is required, HGMLC skips steps 17-23, generates the UE's perception intention based on the UE's perception information, and sends it to the perception request end through SAF.

17. If the privacy check result for the UE in step 16 shows that the UE needs to be notified and verified based on the current location, and the UE is in roaming state, the HGMLC sends a Ngmlc_Location_ProvideLocation instruction to the VGMLC to call the location service operation, thereby sending a positioning awareness request to the VGMLC. For example, the positioning awareness request indicates that the corresponding awareness type is "notification only".

18. When the UE is in roaming state, after receiving the positioning perception request, VGMLC calls the Namf_Location_ProvidePositioningInfo service operation to AMF to request notification and verification of the UE. When the UE is not in roaming state, HGMLC calls the Namf_Location_ProvidePositioningInfo service operation to AMF to request notification and verification of the UE.

19-21. The method in step 19-21 is the same as that in the above steps 6-8 and will not be repeated here.

22. When the UE is in roaming state, the AMF returns the UE's perception information to the VGMLC by calling the command Namf_Location_ProvidePositioningInfo and indicates the result of the notification and verification process performed in steps 20-21.

23. In case of roaming, the VGMLC forwards the notification and indication of the result of the verification procedure to the HGMLC. For non-roaming scenarios, this step is skipped.

24. For example, if the UE allows being sensed by the SAF, the HGMLC sends a positioning service response to the SAF. When the SAF is AF, the positioning service is sent to the SAF through the NEF, and the corresponding NEF sends the positioning service to the SAF by calling the Nnef_EventExposure_Notify instruction, or sends the Nnef_EventExposure_Subscribe instruction to the SAF to execute the location subscription response. If the positioning perception request from the SAF contains a pseudonym, and the HGMLC resolves the GPSI or SUPI corresponding to the UE from the pseudonym in step 1, the HGMLC will use the pseudonym SAF of the UE in the sensing response to the outside. If the SAF requires, the HGMLC may first convert the universal location coordinates provided by the AMF into a location identifier of a local geographic reference system. For example, the HGMLC can also record the charging information of the SAF and the network charging information from the AMF network. The positioning perception service response from the HGMLC to the SAF may include information about the perception method used and the perception estimation information obtained, as well as an accuracy indication of whether the positioning perception request is met. If in step 2, step 15, step 16 or step 23, HGMLC identifies that the UE is not allowed to be sensed by SAF, the location sensing request is rejected and the reason for rejecting the sensing of the UE is indicated in the response. If the level of location service QoS is guaranteed and HGMLC detects that the accuracy of the location sensing request does not meet the standard, HGMLC sends an error response to SAF, which may include the reason for the failure.
