[0047] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0048] The technologies described in this article are not limited to 5th-generation (5G) mobile communication systems and their subsequent evolution, nor are they limited to LTE / LTE evolution (LTE-Advanced, LTE-A) systems. They can also be used in various wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems.

[0049] The terminal provided in this embodiment of the invention can be a mobile phone, tablet computer, laptop computer, ultra-mobile personal computer (UMPC), netbook, personal digital assistant (PDA), mobile internet device (MID), wearable device, or vehicle-mounted device, etc.

[0050] In mobile communication systems, there exist User Equipment (UEs) with various capabilities. For example, a UE may support Proximity Service (ProSe), Vehicle-to-Everything (V2X) communication, and Ranging / Side Link Positioning (Ranging / SLPositioning). Ranging refers to determining the distance and / or direction between two or more UEs and / or the positioning of one UE (referred to as the "target UE") relative to another UE (referred to as the "reference UE") via the PC5 interface. Ranging / Side Link Positioning refers to positioning the UE using the PC5 interface. Therefore, the UE's capability regarding ranging / side link positioning is used to indicate whether the UE is permitted to perform distance measurement, direction measurement, or both.

[0051] Not all UEs need to support ranging-side traversal positioning. Typically, UEs that support ranging-side traversal positioning will support ProSe and / or V2X.

[0052] In order for a UE that supports ranging-side traversal positioning to perform ranging-side traversal positioning services, the network device needs to provide the UE with relevant configuration data, including policies and parameters related to ranging-side traversal positioning services.

[0053] Therefore, how to determine and provide the UE with the configuration data for performing ranging-side walkway positioning services has become an urgent problem to be solved.

[0054] In view of this, the present disclosure provides a method and device for determining the ranging-side traversal positioning strategy. According to the technical solution provided by the present disclosure, the network device can determine the ranging-side traversal positioning strategy for the UE to provide the configuration data required for the ranging-side traversal positioning service, thereby filling the technical gap in the prior art regarding how to determine and provide the UE with the configuration data for performing the ranging-side traversal positioning service.

[0055] Figure 1 A flowchart illustrating a ranging-side walkway positioning policy determination method according to an embodiment of the present disclosure is shown. In this embodiment, the method is executed by a Policy Control Function (PCF) network element, such as... Figure 1 As shown, the method for determining the ranging-side pedestrian link positioning strategy includes the following steps:

[0059] Capability information received from the network element corresponding to the Access and Mobility Management Function (AMF) of the UE, wherein the capability information indicates that the UE supports at least ranging-side proximal positioning; and

[0060] The policy provision request included in the UE policy container received from the UE, wherein the policy provision request includes at least a ranging-side traversal positioning policy provision request for requesting a ranging-side traversal positioning policy.

[0061] In this embodiment, upon receiving capability information from the AMF network element indicating that the UE at least supports ranging-side trespass positioning, the PCF network element can determine a ranging-side trespass positioning strategy for the UE. Alternatively, upon receiving a UE policy container from the UE that includes at least a ranging-side trespass positioning strategy provision request, the PCF network element can determine a ranging-side trespass positioning strategy for the UE. Or, if the PCF network element receives capability information from the AMF network element indicating that the UE at least supports ranging-side trespass positioning and also receives a UE policy container from the UE that includes at least a ranging-side trespass positioning strategy provision request, the PCF network element can determine a ranging-side trespass positioning strategy for the UE.

[0062] In some embodiments, the ranging-side linchpin positioning strategy includes dedicated parameters for the ranging-side linchpin positioning service and common parameters (also referred to as "shared parameters") for both the ranging-side linchpin positioning service and at least one of the ProSe service and V2X service.

[0063] The ranging-side traversal positioning strategy includes configuration data for executing ranging-side traversal positioning services. Specifically, this strategy can include dedicated parameters and common parameters. Dedicated parameters are specifically used for executing ranging-side traversal positioning services. Common parameters can be used for both ranging-side traversal positioning and ProSe services, or both ranging-side traversal positioning and V2X services.

[0064] According to the ranging-side traversal positioning strategy determination method of the present disclosure, the PCF network element can determine the ranging-side traversal positioning strategy for the UE based on the capability information received from the AMF network element and / or the policy provision request included in the UE measurement container from the UE. The ranging-side traversal positioning strategy includes configuration data for performing ranging-side traversal positioning services, thereby filling the technical gap in the prior art regarding how to determine and provide the configuration data for performing ranging-side traversal positioning services to the UE.

[0065] Figure 2 A flowchart illustrating a ranging-side pedestrian link positioning strategy determination method according to an embodiment of the present disclosure is shown. In this embodiment, the method is executed by a PCF network element, such as... Figure 2 As shown, the method for determining the ranging-side pedestrian link positioning strategy includes the following steps:

[0066] S201, based on policy-related information, and based on the PCF network element local policy or information obtained from the Unified Data Repository (UDR) network element, determine the parameters and corresponding parameter values ​​included in the ranging-side walking link positioning policy for the UE.

[0071] Local policies can be pre-configured for PCF network elements. These local policies can indicate the configuration data used to perform ranging-side walkway positioning services. Specifically, they can indicate the required parameters and their values.

[0072] Alternatively, configuration data for performing ranging-side walkway positioning services, including required parameters and their values, can be pre-stored in the UDR network element. The PCF network element can then retrieve the relevant configuration data from the UDR network element.

[0073] In this embodiment, upon receiving capability information from the AMF network element indicating that the UE at least supports ranging-side trespass positioning, the PCF network element can determine the ranging-side trespass positioning strategy for the UE based on its local PCF network element policy or information received from the UDR network element. Alternatively, upon receiving a UE policy container from the UE that includes at least a ranging-side trespass positioning strategy provision request, the PCF network element can determine the ranging-side trespass positioning strategy for the UE based on its local PCF network element policy or information received from the UDR network element. Or, if the PCF network element receives capability information from the AMF network element indicating that the UE at least supports ranging-side trespass positioning and also receives a UE policy container from the UE that includes at least a ranging-side trespass positioning strategy provision request, the PCF network element can determine the ranging-side trespass positioning strategy for the UE based on its local PCF network element policy or information received from the UDR network element.

[0074] In some embodiments, the ranging-side linchpin positioning strategy includes dedicated parameters for the ranging-side linchpin positioning service and common parameters (also referred to as "shared parameters") for both the ranging-side linchpin positioning service and at least one of the ProSe service and V2X service.

[0075] The ranging-side traversal positioning strategy includes configuration data for executing ranging-side traversal positioning services. Specifically, this strategy can include dedicated parameters and common parameters. Dedicated parameters are specifically used for executing ranging-side traversal positioning services. Common parameters can be used for both ranging-side traversal positioning and ProSe services, or both ranging-side traversal positioning and V2X services.

[0076] According to the ranging-side traversal positioning strategy determination method of the present disclosure, the PCF network element can provide a request based on the capability information received from the AMF network element and / or the policy included in the UE measurement container from the UE, and determine the ranging-side traversal positioning strategy for the UE based on the PCF network element's local policy or the information received from the UDR network element. The ranging-side traversal positioning strategy includes configuration data for performing ranging-side traversal positioning services, thereby filling the technical gap in the prior art regarding how to determine and provide the UE with configuration data for performing ranging-side traversal positioning services.

[0077] exist Figure 1 Based on the embodiments shown, this disclosure also provides several embodiments for determining a ranging-side walking link positioning strategy.

[0078] Figure 1 The strategy-related information described in the illustrated embodiments may include different content.

[0079] For example, the content included in strategy-related information may include the following:

[0080] Scenario 1: Policy-related information includes capability information, and the capability information indicates that the UE supports ranging-side walkway positioning and supports ProSe;

[0081] Scenario 2: Policy-related information includes capability information, and the capability information indicates that the UE supports ranging-side walkway positioning and V2X;

[0082] Scenario 3: Policy-related information includes capability information, and the capability information indicates that the UE supports ranging-side walkway positioning, ProSe, and V2X;

[0083] Case 4: Policy-related information includes policy provision requests, and policy provision requests include ranging-side walkway positioning policy provision requests and ProSe policy provision requests used to request ProSe policies;

[0088] Case 9: Policy-related information includes capability information and policy provision requests, and the capability information indicates that the UE supports ranging-side roving positioning, ProSe, and V2X, and the policy provision requests include ranging-side roving positioning policy provision requests.

[0089] Depending on the different contents included in the policy-related information, the ranging-side hop-link positioning policy for the UE can be determined through different embodiments. In the embodiments shown below, the ranging-side hop-link positioning policy may include dedicated parameters for ranging-side hop-link positioning services and common parameters (also referred to as "shared parameters") for both ranging-side hop-link positioning services and at least one of ProSe and V2X services.

[0090] Figure 3 A flowchart illustrating a ranging-side pedestrian link positioning strategy determination method according to an embodiment of the present disclosure is shown. In this embodiment, the method is executed by a PCF network element, and the method is applicable to policy-related information under cases 1, 4, and 7, such as... Figure 3 As shown, the method for determining the ranging-side pedestrian link positioning strategy includes the following steps:

[0091] S301, based on the local policy of the PCF network element or the information received from the UDR network element, determine the dedicated parameters and corresponding parameter values ​​included in the ranging-side walkway positioning policy.

[0092] S302, the parameters and their values ​​included in the ProSe policy used for the UE are determined as common parameters and corresponding parameter values ​​included in the ranging-side walking link positioning policy.

[0093] Local policies can be pre-configured for PCF network elements. These local policies can indicate configuration data used to perform ranging-side walkway positioning services. Specifically, they can indicate dedicated parameters and their values.

[0094] Alternatively, configuration data for performing ranging-side walkway positioning services can be pre-stored in the UDR network element, including dedicated parameters and their values, as well as the values ​​of various common parameters. The PCF network element can obtain the relevant configuration data from the UDR network element.

[0095] Among them, dedicated parameters are used specifically for performing ranging-side linchpin positioning services. Common parameters can be used for both ranging-side linchpin positioning services and ProSe services, or both ranging-side linchpin positioning services and V2X services.

[0096] In this embodiment, when the PCF network element receives capability information indicating that the UE supports ranging-side traversal positioning and ProSe from the AMF network element, the PCF network element can determine the dedicated parameters and corresponding parameter values ​​included in the ranging-side traversal positioning strategy for the UE based on the PCF network element's local policy or the information received from the UDR network element. It can also determine the common parameters and corresponding parameter values ​​included in the ranging-side traversal positioning strategy for the UE based on the parameters and their values ​​included in the ProSe strategy for the UE.
