As shown in fig. 2A, an embodiment of the present disclosure provides an information processing method, wherein the method is performed by a first network device, and the method includes:

s1110: receiving a first request message of first User Equipment (UE), wherein the first request message comprises: identification information and role information of the first UE; wherein the role information indicates a desired role that the first UE acts upon;

s1120: determining whether to allow the location information of the first UE to be exposed according to the privacy configuration of the first UE under the condition that the expected role is to locate the UE;

s1130: and transmitting a first response message containing a discovery key to the first UE under the condition that the position information of the first UE is allowed to be exposed, wherein the discovery key is used for mutual discovery with a second UE serving as a target UE.

The first network device may be a core network device including, but not limited to, at least one of:

the service policy control function (Policy Control Function, PCF) or the proximity service key management function (Prose Key Management Function, PKMF), the direct discovery name management function (Direct Discovery Name Management Function, DDNMF).

In an embodiment of the disclosure, the first network device receives a first request message from a first UE. The first request message may be forwarded or transmitted by the first UE to the first network device through the access network device or other core network device. Illustratively, the first request message is sent by the first UE and forwarded to the PCF, PKMF, or DDNMF via the AMF.

Illustratively, the first request message may include, but is not limited to, a discovery key request (Discovery Key Request, DKR) message. The discovery key request message may also be simply referred to as a discovery key request.

The identification information of the first UE may be various unique identifications that can be recognized by the network device. Illustratively, the identification information of the first UE may include, but is not limited to: a user permanent identifier (Subscriber Permanent Identifier, SUPI) and a user hidden identifier (Subscriber Concealed Identifier, sui).

The role information may indicate a role that the first UE plays when performing a ranging/SL positioning service. Illustratively, the roles indicated by the role information may include: positioning UE and target UE.

The positioning UE may be used to assist in positioning the target UE. The location information of the positioning UE can provide higher-precision positioning for the target UE. The positioning UE is illustratively a UE that can learn absolute position information, and the target UE can obtain the absolute position information of the target UE based on the relative positioning with the positioning UE and by combining the absolute position information of the target UE, where the absolute position information can be longitude and latitude information. If the network equipment is to locate the target UE, more accurate position information of the target UE can be obtained through the assistance of the locating UE.

The target UE may also be referred to as a measured UE. The measured UE may participate in the ranging/SL positioning operation to obtain the ranging/SL positioning result. The ranging/SL positioning results may include a relative distance and/or a relative angle between two measured UEs.

In the embodiment of the present disclosure, if the desired role of the first UE is to be the positioning UE, it is determined whether to allow the location information of the positioning UE to be exposed to the network device and/or other UEs according to the privacy configuration of the positioning UE. For example, it may be determined whether to allow location information of the positioning UE to be exposed to the target UE according to a privacy configuration of the positioning UE.

If the location information of the first UE is allowed to be exposed, the network device obtains the discovery key. The obtaining the discovery key may include: generating a discovery key under the condition that the first network device does not store the discovery key of the associated service; in case there is a discovery key storing the associated service, the generated discovery key is directly acquired. After the network device obtains the discovery key, the discovery key may be returned to the first UE via a first request message. The associated service may be a service indicated by a service code carried by the first request message. In particular, the service may be a ranging/SL positioning service. The discovery key may be used for mutual discovery between the first UE and the second UE. The second UE may then be the target UE for the ranging/SL positioning service.

The discovery key may be generated from a service code, for example. At a time within a public land mobile network (Public Land Mobile Network, PLMN), the network device may have only one valid set of discovery keys for the service code. And storing a valid discovery key in the first network equipment when the first request message of the first UE is received, and directly returning the valid discovery key to the first UE. If the first request message of the first UE is received, the first network device generates a discovery key according to the service code if the first network device does not have a valid discovery key, and sends the generated discovery key to the authorized (or verified) first UE through a first response message.

Notably, are: in some embodiments, S1120 may include:

determining whether to allow the position information of the first UE to be exposed according to the privacy configuration of the first UE under the condition that the first UE is authorized to participate in the service indicated by the service code carried by the first request message according to the subscription data of the first UE; or determining whether the first UE is authorized to allow the location information of the first UE to be exposed according to the privacy configuration of the first UE under the condition that the first UE participates in the service indicated by the service code carried by the first request message to serve as the positioning UE according to the subscription data of the first UE.

If it is determined that the first UE is not authorized to participate in the service indicated by the service code according to the subscription data of the first UE and/or if it is determined that the first UE is not authorized to act as a positioning UE according to the subscription data of the first UE, the step of determining whether to allow the location information of the first UE to be exposed to other UEs according to the privacy configuration of the first UE is skipped. Further, in these cases, a first response message indicating failure may be sent to the first UE.

Illustratively, the method may further comprise:

the first network device requests subscription data and/or privacy configuration of the first UE from the second network device according to the first request message.

The second network device may include, but is not limited to: user data management (User Data Management, UDM) and/or unified data warehouse (Unified Data Repository, UDR).

In some embodiments, the privacy configuration may be part of the subscription data of the first UE. For example, the first UE subscription data indicates that the location information of the first UE is not allowed to be exposed or that the security level is high, and indicates that the configuration information of the first UE is not allowed to be exposed. For another example, the first UE subscription data indicates that the location information of the first UE is allowed to be exposed or that the security level is low, and indicates that the configuration information of the first UE is allowed to be exposed.

The discovery key may include at least one of: an integrity key for integrity protection of messages used when the first UE and the second UE discover each other; confidentiality key for the encryption protection of messages used when discovering each other between the first UE and the second UE.

If the first UE determines, based on its privacy configuration, that the first UE is not allowed to act as a positioning UE, exposing its location information to other UEs if the first UE requests or desires to act as a positioning UE, the first response message may be a reject message. The rejection message does not contain the discovery key and may contain the cause of the failure.

In the embodiments of the present disclosure, on the one hand, the discovery key may be used for security protection of messages delivered by the first UE and the second UE mutual discovery procedure, and on the other hand, whether the discovery key is sent depends on the authorization status of the positioning UE, and further used for controlling whether the location information of the positioning UE is acquired by the target UE.

In some embodiments, the first request message may further include: service codes. The service code may indicate the service currently involved. Illustratively, the service code may indicate ranging/SL location services.

In this way, in the process of issuing the discovery key, the authorization of whether the positioning UE is willing to expose the position information of the positioning UE to other UEs is realized, so that the safety of the position information of the positioning UE is ensured.

The privacy configuration may be user data management (User Data Management, UDM) and/or unified data repository (Unified Data Repository, UDR) for the first network device.

The first network device, after receiving the first request message, may request a privacy configuration of the first UE from the UDM and/or the UDR. For example, a location UE may determine whether to allow its location information to be exposed to other UEs at the time of subscription, at which point a privacy configuration may be generated. At this time, the privacy configuration may be part of the content of the subscription data of the positioning UE, or the privacy configuration specifically generated according to the contract of the subscription data. Also for example, the positioning UE may dynamically update the privacy configuration stored on the first network device and/or UDM and/or UDR by updating the flow based on the user indication to determine whether it is willing to expose the own location information.

In some embodiments, the privacy configuration of the positioning UE may be a common configuration with the positioning UE belonging to the same type of UE, or a personalized configuration of the positioning UE. If so, determining the privacy configuration shared by the UE of the type according to the type of the first UE, and further determining whether the position information of the first UE is allowed to be exposed. If so, inquiring the personal configuration of the first UE according to the identification information of the first UE, and determining whether the position information of the first UE is allowed to be exposed or not according to the personal configuration. For example, it is possible for multiple UEs belonging to a community of business, government, home, public welfare organization, etc. to have the same privacy configuration, i.e. the UEs share a common set of common configurations.

In other embodiments, if a common configuration and a personality configuration are present at the same time, the priority of the personality configuration is higher than the priority of the common configuration. If no personality exists, a common configuration is used to determine whether to allow the location information of the first UE that is expected to act as a positioning UE to be exposed to other UEs.

In still other embodiments, if privacy configurations, such as public and personal configurations, are not present, it may be considered that determining location information of a first UE requesting to act as a positioning UE is allowed to be exposed to other UEs.

As shown in fig. 2B, an embodiment of the present disclosure provides an information processing method, wherein the method is performed by a first network device, and the method includes:

s1210: receiving a first request message of first User Equipment (UE), wherein the first request message comprises: identification information and role information of the first UE; wherein the role information indicates a desired role that the first UE acts upon;

s1220: sending a verification notification to the first UE if the desired role is to locate the UE and if the privacy configuration of the first UE includes a notification indicator;

s1230: receiving notification feedback of the first UE;

s1240: determining whether to allow the location information of the first UE to be exposed according to the notification feedback;

s1250: transmitting a first response message including a discovery key to the first UE in a case where the location information of the first UE is allowed to be exposed, wherein the first response message includes: discovering a secret key; the discovery key is used for mutual discovery with a second UE serving as a target UE.

In the embodiment of the disclosure, it may be determined by information interaction with the first UE whether the first UE is allowed to be exposed to other UEs when it desires to act as a positioning UE. This is also a way to verify if a first UE is allowed to expose its location information to other UEs in the event that it is desired to act as a positioning UE. And in this manner, the user of the first UE may temporarily determine if his own location information is allowed to be exposed to other UEs as needed.

In this case, the privacy configuration of the first UE may include, alone: a notification indicator. The notification indicator is used for indicating that whether the position information of the first UE is allowed to be exposed or not is dynamically determined by means of verification notification and notification feedback of the first UE.

For example, the first UE may send a first request message to the first network device based on the triggering of the application. The operating system of the first UE may have a setting item that the location information of the first UE is kept secret or not allowed to be exposed, in which case, after receiving the authentication notification returned by the first network device, the first UE returns notification feedback to the first network device according to the setting item of the operating system or based on an operation instruction received from a User Interface (UI). The notification feedback indicates whether the location information of the first UE is allowed to be exposed.

As shown in fig. 2C, an embodiment of the present disclosure provides an information processing method, wherein the method is performed by a first network device, and the method includes: s1310: receiving a first request message of first User Equipment (UE), wherein the first request message comprises: identification information and role information of the first UE; wherein the role information indicates a desired role that the first UE acts upon;

S1320: determining whether to allow the location information of the first UE to be exposed according to the privacy configuration of the first UE under the condition that the expected role is to locate the UE;

s1330: sending a verification notification to the first UE if the desired role is to locate the UE and the location information of the first UE is determined to be allowed to be exposed according to the privacy configuration;

s1340: receiving notification feedback of the first UE;

s1350: determining again whether to allow the location information of the first UE to be exposed according to the notification feedback;

s1360: transmitting a first response message including a discovery key to the first UE in case the notification feedback indicates that the first UE location information is allowed to be exposed; and sending a first response message which does not contain a discovery key to the first UE in the condition that the notification feedback indicates that the first UE position information is not allowed to be exposed.

Finally, the first network device determines whether to allow the first UE to participate in the SL positioning service and act as a positioning UE according to the notification feedback of the first UE, and whether to allow the location information of the first UE to be exposed to other UEs.

In some embodiments, the first response message is sent to the first UE without the discovery key if the privacy configuration determines that the location information of the first UE is not allowed to be exposed. In this case, the first response message may also include a failure indication.

In some embodiments, the determining whether to verify whether to allow the location information of the first UE to be exposed according to the notification feedback includes:

determining that the location information of the first UE is allowed to be exposed in case the notification feedback indicates acknowledgement;

and in the case that the notification feedback indicates denial, determining that the location information of the first UE is not allowed to be exposed.

In some embodiments, the sending, to the first UE, a verification notification if the desired role is to locate the UE, includes:

a verification notification is sent to the first UE if the desired role is to locate the UE and the privacy configuration includes a notification indicator.

If the privacy configuration contains the notification indicator, it is only necessary to determine whether to allow the location information of the first UE to be exposed to other UEs through interaction with the verification notification and the notification feedback of the first UE, otherwise it may be determined whether to allow the location information of the first UE to be exposed to other UEs based on the privacy configuration alone.

In some embodiments, the determining whether to allow the location information of the first UE to be exposed according to the privacy configuration of the first UE in the case that the desired role is to locate the UE further includes:

In the case where the desired role is to locate a UE and the privacy configuration does not include a notification indicator, determining whether to allow location information exposure of the first UE according to the privacy configuration of the first UE.

In some embodiments, the method further comprises:

in case the first UE is allowed to act as a target UE, a first response message comprising the discovery key is sent to the target UE.

Illustratively, the role information indicates that the first UE is acting as a target UE when participating in the ranging/SL positioning service, and if it is determined that the first UE is authorized or allowed to act as the target UE according to subscription data of the target UE, a first response message including a discovery key is sent to the target UE. As such, the discovery key may be used for a first UE acting as a target UE to discover a second UE that locates the UE.

In some embodiments, if the first response message includes a discovery key, the first response message may also include a timestamp and a maximum offset value. The timestamp may be used to indicate a start time at which the discovery key carried by the current first response message is validated, and the maximum offset may be used to determine an end time at which the discovery key carried by the current first response message is validated.

After the first UE receives the discovery key, an effective period of the discovery key is determined according to the timestamp and the maximum offset, and the discovery key and the second UE are mutually discovered in the effective period.

Illustratively, the timestamp may be a timestamp of the time of generation of the discovery key.

In some embodiments, if the first UE is allowed to act as the target UE, the first response message may further include: information of the UE is located. For example, the information of the positioning UE may be carried in a UE list, so that the subsequent target UE can find the positioning UE through the announcement message.

In one embodiment, the first network device also needs to verify whether the first UE is allowed to act as a positioning UE. If the first UE is allowed to act as a positioning UE, it is determined whether the location information of the first UE is allowed to be exposed according to the privacy configuration of the first UE.

That is, in this case, a first response message including a discovery key is transmitted to the first UE in a case where the first UE is allowed to act as the positioning UE and the location information of the first UE is allowed to be exposed, and otherwise, a first response message not including a discovery key is transmitted to the first UE. The first response message that does not contain the discovery key may include: failure indication.

For example, the first network device may determine whether the first UE is capable of participating in the ranging/SL positioning service and/or is capable of acting as a positioning UE when participating in the ranging/SL positioning service according to subscription data of the first UE. If the first UE cannot participate in the ranging/SL positioning service, or if the first UE can participate in the ranging/SL positioning service but cannot act as a positioning UE, the first UE may be considered to be unable to act as a positioning UE; denial this may consider the first UE to be able to act as a positioning UE.

In some embodiments, only if the first UE is allowed to act as a positioning UE, it is determined from the privacy configuration whether to allow verification that the location information of the first UE is exposed, thereby ensuring, on the one hand, security of service execution and, on the other hand, security of positioning UE location information participating in performing the ranging/SL positioning service.

Illustratively, the first request message may include: and the service code inquires the subscription data of the first UE according to the service code and the identification information of the first UE, and performs the verification after receiving the subscription data.

Still further exemplary, the first request message may further include: the service code and the identification information of the first UE. After the first network device receives the first request message, the service code, the identification information of the first UE and the role information carried by the first request message may be given to a second network device such as UDM and/or UDR, and a query result returned by the second network device may be received, where the query result may directly indicate whether the first UE is allowed to act as a positioning UE, or may also return subscription data to the first network device.

As shown in fig. 3A, an embodiment of the present disclosure provides an information processing method, which is performed by a first UE, the method including:

s2110: transmitting a first request message to a first network device, wherein the first request message comprises: identification information and role information of the first UE; wherein the role information indicates a desired role that the first UE acts upon;

s2120: receiving a first response message returned by the first network equipment; wherein in case the first UE is allowed to act as a positioning UE and the determination from the privacy configuration indicates that the location information of the first UE can be exposed, the first response message comprises: discovering a secret key; the discovery key is used for discovering with the second UE.

Udm returns privacy configuration of the positioning UE to DDNMF, PCF or PKMF through nudm_sdm_get response.

The DDNMF, PCF or PKMF checks whether the positioning UE allows the location information to be acquired by the network according to the privacy configuration of the UE. Illustratively, it is determined whether the location information of the positioning UE is allowed to be exposed, i.e. according to the privacy configuration of the positioning UE.

6. Alternatively, if the indicator of the privacy check related action indicates that the UE must be notified for privacy verification, the DDNMF, PCF or PKMF notifies the UE through the AMF, which notification may include the service code of the SL location service. And then, through user interaction, the UE returns a notification result to the DDNMF, the PCF or the PKMF through the AMF, wherein the notification result indicates whether the user authorizes or refuses the current SL positioning service, if the user authorizes, the user currently agrees to position the UE to be exposed, and if the user refuses, the user does not currently agree to position the UE to be exposed. The location notification call in fig. 4A is one of the aforementioned verifications. The position notification feedback in fig. 4A is one of the feedback notifications described above.

9. The positioning UE starts broadcasting an announcement message containing its own UE information and a service code of the SL positioning service. And protects the advertisement message using the received discovery key.

10. The target UE monitors the broadcast announcement message. If the UE information of the location UE in the advertisement message matches the location UE information provided by the LMF, the target UE sends a discovery key request to the DDNMF, PCF or PKMF, the request including at least a UE ID, a service code of the SL location service, and role information the UE is to play (i.e., the target UE).

Ddnmf, PCF or PKMF contacts UDM to check if the UE is authorized as a target UE for SL location services based on its subscription information.

The ddnmf, PCF or PKMF returns a discovery key response to the UE including all discovery security information generated in step #7 a.

13. After receiving the discovery security information, the target UE can verify the received advertisement message.

14. The target UE selects the positioning UE by sending a direct communication request (Direct Communication Request, DCR) message to the positioned UE.

15. The positioning UE returns a direct communication accept (Direct Communication Accept, DCA) message to the target UE.

16. The remainder of the SL positioning procedure is completed.

As shown in fig. 4B, an embodiment of the present disclosure provides an information processing method, which may include:

2. If the role is to be played as a positioning UE, the DDNMF, PCF or PKMF contacts UDM and checks whether the UE is authorized as a positioning UE for the SL positioning service based on its subscription information.

The DDNMF, PCF or PKMF checks whether the positioning UE allows the location information to be acquired by the network according to the privacy configuration of the UE.

6. Alternatively, if the indicator of the privacy check-related action indicates that the UE must be notified of privacy verification, the DDNMF, PCF or PKMF notifies the UE through the AMF that the notification includes the service code of the SL location service.
