As shown in fig. 2, an embodiment of the present disclosure provides an information processing method, which is performed by an AMF, and may include:

s110: receiving a first request of a first UE; the first request is for requesting to perform ranging and/or SL positioning services; the first request carries a first ID of the first UE and/or a second ID of the second UE;

s120: transmitting a second request to the GMLC based on the first request; the second request is for determining whether the first UE and/or the second UE is authorized to perform ranging and/or SL positioning services;

s130: receiving a response message of the GMLC; the response message is used to indicate whether the first UE and/or the second UE is authorized successfully.

In the embodiments of the present disclosure, the first UE may be a target UE or a positioning UE, where in the ranging and/or SL positioning service, the target UE may discover one or more positioning UEs and perform the ranging and/or SL positioning service with the one or more positioning UEs, for example, the target UE may determine more accurate location information of the target UE based on the location of the positioning UE and the distance, direction, etc. between the target UE and the positioning UE.

In one embodiment, ranging services refer to determining a relative distance between a first UE and a second UE and/or a relative direction between UEs, such as a direction of a target UE relative to a positioning UE or a direction of a positioning UE relative to a target UE, by direct communication. SL location services refer to the target UE obtaining a more accurate absolute position of the target UE based on the relative position or ranging information of the target UE and the positioning UE, and the absolute position of the positioning UE, for example, by using a direct communication (PC 5) interface.

In one embodiment, the ranging and/or SL positioning service may be a network assisted ranging and/or SL positioning service, e.g., the network assistance may be terminal originated location request (Mobile Originated Location Request, MO-LR) network assistance. The first request may be a ranging and/or SL location service request sent by the first UE, e.g., may carry a first identity (Identity Document, ID) of the first UE and/or a second ID of the second UE, etc. that participates in the requested ranging and/or SL location service. Here, the ID may uniquely identify the corresponding UE, and may be, for example, a general public user identity (Generic Public Subscription Identifier, GPSI), a user permanent identifier (Subscription Permanent Identifier, SUPI), a user hidden identifier (Subscription Concealed Identifier, sui), an application layer identity (application layer ID), or a user information identity (user info ID), etc.

Wherein, when the first UE is the target UE, the first request may carry a first ID of the first UE and a second ID of at least one second UE discovered by the first UE, where the second UE is a positioning UE. When the first UE is a positioning UE, the first request may carry a second ID of a second UE that discovers the first UE and the first ID of the first UE, where the second UE is a target UE.

In one embodiment, sending the second request to the GMLC based on the first request may include determining the second request based on the first request and sending the second request to the GMLC. The second request may be determined based on the ranging and/or SL positioning service indicated by the first request, and may also be determined based on the first ID and/or the second ID carried by the first request.

In one embodiment, the second request may be at least for determining whether the first UE and/or the second UE is authorized to perform ranging and/or SL positioning services, e.g., the second request may be an authorization request or the like. For example, the second request may be an ngmlc_location_provisioning service operation, which may carry indication information to request the GMLC to check the authorization status of the first UE and/or the second UE. For example, the second request may carry the first ID and/or the second ID in the first request, for the GMLC to determine a unified data management network element (Unified Data Management, UDM) corresponding to the first UE and/or the second UE.

Here, the second request may also be other requests, for example, a request sent by the AMF to the GMLC for obtaining some information, where the request is further used for the AMF to request the GMLC to return mapping information of the first ID and/or the second ID of the first UE and/or the second UE, for example, mapping to an internal network identifier SUPI, etc., and meanwhile, the first ID and/or the second ID carried by the message may determine the authorization condition of the first UE and/or the second UE, so that signaling overhead generated by separately sending the authorization request may be reduced.

In one embodiment, the response message sent by the GMLC may be a response message sent based on the second request, for example, the response message may be a first message indicating that the first UE and/or the second UE authorization is successful, or the response message may be a second message indicating that the first UE and/or the second UE authorization is failed. For example, the second message may be a reject message indicating rejection of the ranging and/or SL positioning service corresponding to the second request.

Wherein the success of the first UE and/or the second UE authorization means that the first UE and/or the second UE authorization performs ranging and/or SL positioning service, and the failure of the first UE and/or the second UE authorization means that the first UE and/or the second UE is not authorized to perform ranging and/or SL positioning service.

In one embodiment, the method further comprises: receiving a third request of the GMLC; location information of the first UE and/or the second UE is sent to the GMLC. The third request may be used to request to obtain Location information of the first UE and/or the second UE, for example, the third request may be a request corresponding to "namf_location_providelocalinfo". The location information of the target UE and/or the positioning UE may be location information provided for a network corresponding to the first UE and/or the second UE, where the location information provided by the network records the latest location information stored by the first UE and/or the second UE on the network side.

In one embodiment, the Location information of the first UE and/or the second UE is sent to the GMLC, which may be, for example, a "namf_location_providelocalinfo" response message, and a response message is returned to the GMLC. The response information may carry location information provided by the network of the first UE and/or the second UE.

In one embodiment, after step S130, the method may further include: it is determined whether the first UE performs ranging and/or SL positioning services based on the response message. Wherein, under the condition that the response message indicates that the first UE and/or the second UE is authorized successfully, determining that the first UE executes ranging and/or SL positioning service; or, in case the response message indicates that the first UE and/or the second UE fails to grant, determining that the first UE does not perform ranging and/or SL positioning service.

In one embodiment, determining that the first UE is performing ranging and/or SL positioning services may include: -selecting a location management function network element (Location Management Function, LMF); a ranging and/or SL location service request is sent to the LMF. The LMF may trigger or instruct the first UE to perform ranging and/or SL location services based on the ranging and/or SL location service request.

When the first UE is a target UE, the ranging and/or SL positioning service performed by the first UE may be a ranging and/or SL positioning service performed by one or more positioning UEs discovered by the target UE and the target UE. When the first UE is a positioning UE, the ranging and/or SL positioning service performed by the first UE may be a ranging and/or SL positioning service performed by the positioning UE and a target UE that discovers the positioning UE.

In one embodiment, the first UE may perform ranging and/or SL positioning services based on the LMF, which may refer to the LMF sending an instruction to the first UE through the AMF to instruct the first UE to perform ranging and/or SL positioning services, i.e., the first UE may perform ranging and/or SL positioning services based on the instruction forwarded by the LMF through the AMF, e.g., the instruction may be a trigger instruction, etc.

In one embodiment, the method may further comprise: receiving ranging and/or SL positioning service results returned by the LMF; and sending the ranging and/or SL positioning service result to the first UE. The ranging and/or SL positioning service results may include, among other things, measurement data and/or positioning results. The measurement data and/or positioning results may include: the relative direction between the first UE and the second UE, for example, the direction of the target UE with respect to the positioning UE or the direction of the positioning UE with respect to the target UE, or the relative position or ranging information of the target UE and/or the positioning UE, or the absolute position of the positioning UE, or the calculated absolute position of the target UE, etc.

In this way, before the ranging and/or SL positioning service is performed, the target UE and/or the positioning UE is subjected to authorization checking, so that the security of the location information in the ranging and/or SL positioning service process can be improved, and the acquisition of the location information by an unauthorized UE is reduced, thereby improving the privacy protection of the UE.

The technical features described in the foregoing embodiments may be arbitrarily combined in any arrangement and order without contradiction, and may be arbitrarily combined into a new method technical scheme.

It should be noted that, as those skilled in the art may understand, the methods provided in the embodiments of the present disclosure may be performed alone or in combination with some methods in the embodiments of the present disclosure or other embodiments or some methods in the related art.

In some embodiments, as shown in fig. 3, the method may further comprise:

s141: determining that the first UE performs ranging and/or SL positioning service under the condition that the response message indicates that the target UE and/or the positioning UE is authorized successfully;

or,

s142: in case the response message indicates that the target UE and/or the positioning UE authorization fails, it is determined that the first UE does not perform ranging and/or SL positioning services.

In one embodiment, the first UE is a target UE and the second UE is a positioning UE; or the first UE is a positioning UE, and the second UE is a target UE.

In one embodiment, the second request carries the first ID and/or the second ID. For example, the second request includes the first ID and/or the second ID carried by the first request.

Thus, the first ID and the second ID can be used by the GMLC to determine the UDM corresponding to the target UE and the positioning UE, so that the required information can be acquired more quickly to check the authorization condition of the target UE and the positioning UE.

In some embodiments, after step S120, and before step S130, as shown in fig. 4, the method may further include:

s150: receiving a third request of the GMLC;

s160: location information of the first UE and/or the second UE is sent to the GMLC.

Here, the location information is used to determine whether the first UE and/or the second UE are within a predetermined range; the predetermined range is a range of areas in which the first UE and/or the second UE are allowed to perform ranging and/or SL positioning services.

In one embodiment, the third request may be for requesting to obtain Location information of the first UE and/or the second UE, for example, the third request may be a request corresponding to "namf_location_providelocalinfo". The location information of the first UE and/or the second UE may be location information provided for a network of the first UE and/or the second UE, where the location information provided by the network records the latest location information stored by the first UE and/or the second UE at the network side.

In one embodiment, the location information may be used to determine whether the location of the first UE and/or the second UE is within a predetermined range, which may be a range of areas where the first UE and/or the second UE is allowed to perform ranging and/or SL positioning services.

In this way, the location information sent to the GMLC may be used by the GMLC to determine whether the location of the first UE and/or the second UE meets the location requirement corresponding to the authorization check, thereby improving the accuracy of the authorization check.

In one embodiment, the response message includes: a first message indicating that the first UE and/or the second UE authorization is successful, or a second message indicating that the first UE and/or the second UE authorization is failed.

Therefore, the authorization condition of the first UE and/or the second UE can be more accurately indicated to the AMF based on different response messages, so that the AMF can conveniently determine whether the first UE can execute ranging and/or SL positioning service, and the processing efficiency is improved.

In some embodiments, determining that the first UE performs ranging and/or SL positioning services comprises:

a ranging and/or SL location service request is sent to the LMF.

In one embodiment, before sending the ranging and/or SL location service request to the LMF, the method further comprises:

LMF is selected.

In one embodiment, the AMF sends a ranging and/or SL location service request to the LMF, which may be used to instruct the LMF to participate in the ranging and/or SL location service performed by the first UE.

In this way, the accuracy of ranging and/or SL positioning service control may be improved based on the LMF and the first UE starting to perform the ranging and/or SL positioning service.

For the description of the repeated or corresponding content with other embodiments, please refer to the steps corresponding to fig. 2 and related parts of the content in the alternative embodiment, which are not described herein.

As shown in fig. 5, an embodiment of the present disclosure provides an information processing method, performed by a GMLC, including:

s210: receiving a second request sent by the AMF;

s220: determining whether the first UE and/or the second UE is authorized to perform ranging and/or SL positioning services based on the second request;

s230: and sending a response message to the AMF, wherein the response message is used for indicating whether the first UE and/or the second UE is authorized successfully or not.

In embodiments of the present disclosure, the second request may be at least for determining whether the first UE and/or the second UE is authorized to perform ranging and/or SL positioning services, e.g., the second request may be an authorization request or the like. For example, the second request may be an ngmlc_location_provisioning service operation, which may carry indication information to request the GMLC to check the authorization status of the first UE and/or the second UE. For example, the second request may carry the first ID and/or the second ID in the first request, for the GMLC to determine the UDM corresponding to the first UE and/or the second UE. Here, the ID may uniquely identify the corresponding UE, and may be GPSI, SUPI, SUCI, application layer ID, or a user info ID, for example.

The second request may here also be another request, for example a request sent by the AMF to the GMLC for obtaining some information,

The request is also used for the AMF to request the GMLC to return mapping information of the first ID and/or the second ID of the first UE and/or the second UE, such as a mapped network internal identifier SUPI and the like, and meanwhile, the first ID and/or the second ID carried by the message can determine the authorization condition of the first UE and/or the second UE, so that signaling overhead generated by independently sending the authorization request can be reduced. In one embodiment, the response message may be used for the AMF to determine whether the first UE is capable of performing ranging and/or SL positioning services. The first UE is a UE that sends a first request to the AMF, e.g., the first UE may be a target UE or a positioning UE.

In one embodiment, step S220 may include: determining the UDM corresponding to the first UE based on the first ID, and/or determining the UDM corresponding to the second UE based on the second ID; acquiring an authorization result and/or first information of the first UE and/or the second UE from the UDM; and determining the authorization condition of the first UE and/or the second UE based on the authorization result and/or the first information sent by the UDM.

Here, determining the UDM corresponding to the first UE based on the first ID may include directly determining the UDM corresponding to the first UE based on the first ID, for example, the first ID may be GPSI or the like, or may also include determining SUPI and/or sui corresponding to the first UE based on the first ID, and determining the UDM corresponding to the first UE based on SUPI and/or sui corresponding to the first UE.

Similarly, for determining the UDM corresponding to the second UE based on the second ID, the manner of determining the UDM corresponding to the first UE based on the first ID is similar, and will not be described herein.

In one embodiment, an authorization result and/or first information of the first UE and/or the second UE is obtained from the UDM, where the first information may include subscription data (subscription data) and/or a privacy profile (privacy profile), the authorization result may be an authorization result determined by the UDM based on the first information, for example, the authorization result may be determined by the UDM based on the subscription data of the first UE and/or the second UE, and may indicate whether information carried in the ranging and/or SL positioning request matches an authorization role of the first UE and/or the second UE.

Illustratively, the GMLC may obtain the authorization result and/or the first information from the UDM through a "nudm_sdm_get" service. The UDM may return the authorization result directly or return the first information for the GMLC to perform authorization checking.

In one embodiment, the first information acquired from the UDM includes subscription data, and determining the authorization status of the first UE and/or the second UE based on the authorization result and/or the first information sent by the UDM may include: determining whether information carried in a ranging and/or SL positioning request is matched with an authorized role of the first UE and/or the second UE or not based on subscription data sent by the UDM; and under the condition of matching the authorization roles, determining that the first UE and/or the second UE is successfully authorized.

Here, the authorization role refers to a role that the UE is authorized, for example, in the ranging and/or SL positioning request, where the first ID is indicated as the ID of the target UE, if the authorization role of the UE corresponding to the first ID includes the target UE, it is determined that the authorization roles of the target UE match, and if the authorization role of the UE corresponding to the first ID does not include the target UE, that is, the UE corresponding to the first ID is not authorized as the target UE, it is determined that the authorization roles of the target UE do not match.

In one embodiment, the first information may further include: privacy profiles. Determining whether the first UE and/or the second UE is authorized to perform ranging and/or SL positioning services based on the authorization result and/or the first information sent by the UDM may include: in case it is determined that the authorized roles of the first UE and/or the second UE match based on the authorization result and/or the first information sent by the UDM, it is determined whether the first UE and/or the second UE is authorized to perform ranging and/or SL positioning service based on the privacy profile.

The authorization result may be a result of the UDM determining whether the authorization roles of the first UE and/or the second UE match based on the subscription data. Determining whether the first UE and/or the second UE is authorized to perform ranging and/or SL positioning services based on the privacy profile may include: determining whether the first UE and/or the second UE authorizes the ranging and/or SL positioning service corresponding to the second request based on the privacy configuration file; and determining that the first UE and/or the second UE is authorized successfully under the condition that the first UE and/or the second UE is authorized for ranging and/or SL positioning service.

In one embodiment, determining whether the first UE and/or the second UE grants the ranging and/or SL positioning service corresponding to the second request based on the privacy profile may include: based on the privacy profile and the subscription data, it is determined whether the first UE and/or the second UE authorizes the ranging and/or SL positioning service corresponding to the second request. The privacy profile may exist independently of the subscription data, or may be partially or completely included in the subscription data.

In one embodiment, when the first UE and/or the second UE grants ranging and/or SL positioning services, the method may further comprise: determining whether the privacy profile indicates a predetermined range; the predetermined range is a range of areas in which the first UE and/or the second UE are allowed to perform ranging and/or SL positioning services; in the case that the privacy profile indicates a predetermined range, sending a third request to the AMF; receiving position information of a first UE and/or a second UE sent by an AMF; determining whether the first UE and/or the second UE are within a predetermined range based on the location information; and determining that the first UE and/or the second UE is authorized successfully in response to the first UE and/or the second UE being within the predetermined range.

Here, the predetermined range may be recorded in the privacy profile.

In one embodiment, when it is determined that the first UE and/or the second UE is successfully authorized, a first message is sent to the AMF.

In one embodiment, when it is determined that the first UE and/or the second UE fails to grant based on the grant result and/or the first information, a second message is sent to the AMF, where the second message may be a reject message to indicate that the ranging and/or SL positioning service corresponding to the second request is rejected.

Wherein determining that the first UE and/or the second UE fails to grant based on the grant result and/or the first information may include at least one of: determining that the authorized roles of the first UE and/or the second UE are not matched based on the authorized result and/or the subscription data; determining ranging and/or SL positioning services corresponding to the first UE and/or the second UE unauthorized second request based on the privacy configuration file; the first UE and/or the second UE are not located within a corresponding predetermined range.

In this way, before the ranging and/or SL positioning service is performed, the first UE and/or the second UE are subjected to authorization checking, so that the security of the location information in the ranging and/or SL positioning service process can be improved, and the acquisition of the location information by an unauthorized UE is reduced, thereby improving the privacy protection of the UE.

In some embodiments, as shown in fig. 6, step S220 may include:

S221: determining the UDM corresponding to the target UE based on the first ID, and/or determining the UDM corresponding to the positioning UE based on the second ID;

s222: acquiring an authorization result of the target UE and/or the positioning UE from the UDM;

s223: based on the authorization result, it is determined whether the first UE and/or the second UE is authorized to perform ranging and/or SL positioning services.

Here, determining the UDM corresponding to the first UE based on the first ID may include directly determining the UDM corresponding to the first UE based on the first ID, for example, the first ID may be GPSI or the like, or may also include determining SUPI and/or sui corresponding to the first UE based on the first ID, and determining the UDM corresponding to the first UE based on SUPI and/or sui corresponding to the target UE.

Therefore, through the first ID and/or the second ID, the corresponding UDM can be accurately and quickly searched, and information required by authorization checking can be conveniently acquired. Moreover, the UDM can directly provide the authorization result, and can also perform authorization checking according to the first information, so that the flexibility of the authorization checking is improved.

In some embodiments, as shown in fig. 7, step S220 may include:

S224: determining the UDM corresponding to the first UE based on the first ID, and/or determining the UDM corresponding to the second UE based on the second ID;

s225: acquiring first information of a first UE and/or a second UE from the UDM;

s226: it is determined whether the first UE and/or the second UE is authorized to perform ranging and/or SL positioning services based on the first information.

In one embodiment, the first information includes: subscription data;

step S226 may include:

determining whether the authorized roles of the first UE and/or the second UE match based on the subscription data;

and under the condition of matching the authorization roles, determining that the first UE and/or the second UE is successfully authorized.

Therefore, based on the checking of the authorized roles, whether the current roles of the first UE and/or the second UE are authorized or not can be primarily determined, if not, the authorization failure is directly determined, so that subsequent checking is not needed when the authorized roles are not matched, and the time required by the authorization checking is reduced based on primary screening.

In one embodiment, the first information further comprises: a privacy profile;

determining that the first UE and/or the second UE is successfully authorized includes:

determining whether the first UE and/or the second UE authorizes the ranging and/or SL positioning service corresponding to the second request based on the subscription data and/or the privacy configuration file;

And determining that the first UE and/or the second UE is authorized successfully under the condition that the first UE and/or the second UE is authorized for ranging and/or SL positioning service.

Therefore, based on the checking of the two layers of the authorization role and the service authorization, the authorization checking can be performed on the identity of the UE and the requested ranging and/or SL positioning service comprehensively and accurately, and the authorization reliability and the security are improved.

In one embodiment, in a case where the first UE and/or the second UE grants the ranging and/or the SL positioning service, determining that the first UE and/or the second UE grants the ranging and/or the SL positioning service successfully includes:

determining whether the privacy profile indicates a predetermined range; the predetermined range is a range of areas in which the first UE and/or the second UE are allowed to perform ranging and/or SL positioning services;

in the case that the privacy profile indicates a predetermined range, sending a third request to the AMF;

receiving position information of a first UE and/or a second UE sent by an AMF;

determining whether the first UE and/or the second UE are within a predetermined range based on the location information;

and determining that the first UE and/or the second UE is authorized successfully in response to the first UE and/or the second UE being within the predetermined range.

Therefore, based on whether the position of the UE and the privacy requirement are met, the authorization condition of the UE is further confirmed, and the authorization reliability and the security are further improved.

In one embodiment, the response message includes: a first message indicating that the first UE and/or the second UE is successfully authorized; or, a second message indicating that the first UE and/or the second UE has failed authorization.

example 1:

in this embodiment, as shown in fig. 11, if the target UE has NAS connection with the AMF (directly or indirectly through ProSe UE-to-Network Relay), UE1 refers to the target UE, and UE2 refers to the positioning UE. If the target UE cannot establish a NAS connection with the AMF, UE1 refers to a positioning UE and UE2 refers to the target UE.

In the embodiments of the present disclosure, UE1 corresponds to the first UE in the previous embodiments, and UE2 corresponds to the second UE in the previous embodiments.

1. The target UE performs discovery and selection of the positioning UE. After the SL location discovery procedure, the target UE stores the ID(s) of the located UE.

2. The target UE or positioning UE sends a Ranging (Ranging) and/or SL positioning service request to its AMF, including the target UE ID and/or positioning UE ID. Here, the target UE ID corresponds to the first ID in the foregoing embodiment, and the positioning UE ID corresponds to the second ID in the foregoing embodiment.

3. To check the authorization of the locating UE and/or the target UE, the AMF sends an authorization request to the GMLC. Based on the positioning UE ID and/or the target UE ID, the GMLC obtains its sui and/or SUPI and finds the corresponding UDM(s).

The gmlc invokes a nudm_sdm_get Request service operation to the UDM of the positioning UE and/or the target UE to obtain first information and/or authorization result of the UE, wherein the first information may include a privacy profile and/or subscription data.

Udm returns subscription data and/or privacy profile and/or authorization result of target UE and/or positioning UE through nudm_sdm_get Response.

Alternatively, step 4 and step 5 may be omitted, and the gmlc may store or have acquired the first information of the positioning UE and/or the target UE.

And 6, the GMLC judges whether the authorized roles of the positioning UE and/or the target UE are matched according to the subscription data and/or the authorized result. If the authorized roles match, the GMLC further verifies the privacy requirements of the target UE and/or the locating UE using the subscription data and/or the privacy profile. If the target UE and/or the positioning UE is authorized to use the network-assisted SL positioning service and grants the requested SL positioning service with authorization, the GMLC proceeds to step #7. If the authorized roles do not match, or the target UE and/or the positioning UE are not allowed to be positioned, the GMLC returns a reject message.

The GMLC may request the subscription data and/or the privacy profile and/or the authorization result at one time, or may request the subscription data and the privacy profile and the authorization result respectively (e.g., after the authorization role passes, the GMLC invokes the nudm_sdm_get service operation again to obtain the privacy profile).

The gmlc returns the authorization result to the AMF.

8. If the authorization check is successful, the AMF selects an LMF.

And triggering SL positioning procedure by LMF to position the positioning UE.

After the sl positioning measurement is finished, the LMF returns the positioning UE location, the measurement result, or the target UE location.

AMF forwards ranging and/or SL positioning results.

Example 2:

as shown in fig. 12, the method includes:

The GMLC calls Nudm_SDM_get Request service operation to the UDM of the positioning UE and/or the target UE to obtain first information and/or authorization result of the UE, wherein the first information can be privacy configuration file and/or subscription data.

7. If the rights granted by the target UE and/or the positioning UE are restricted to a certain area, the GMLC invokes a namf_location_ ProvideLocationInfo request service operation to the AMF requesting the network to provide network-provided Location information of the UE.

AMF returns Namf_location_ ProvideLocationInfo response response to GMLC to return Location information provided by the network of the target UE and/or the positioning UE. Based on location information provided by the network of the target UE and/or the positioning UE, the GMLC checks whether the target UE and/or the positioning UE is within the area of the service authorization.

The gmlc returns the authorization result to the AMF.

10. If the authorization check is successful, the AMF selects an LMF.

And the LMF triggers SL positioning procedure to position the positioning UE.

AMF forwards ranging and/or SL positioning results.
