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

[0048] The technology described in this article is not limited to the fifth-generation mobile communication (5th-generation, 5G) system and subsequent evolution communication systems, and is not limited to the evolution (LTE-Advanced, LTE-A) system of LTE / LTE, and can also be used in various wireless communication systems, such as Code Division Multiple Access (Code Division Multiple Access, CDMA), Time Division Multiple Access (Time Division Multiple Access, TDMA), Frequency Division Multiple Access (Frequency Division Multiple Access, FDMA), Orthogonal Frequency Division Multiple Access (Orthogonal Frequency Division Multiple Access, OFDMA), Single-carrier Frequency Division Multiple Access (Single-carrier Frequency-Division Multiple Access, SC-FDMA) and other systems.

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

[0050] In a mobile communication system, there are user equipment (UE) with various capabilities. For example, the UE can support proximity service (ProSe), vehicle to everything (V2X), ranging / side link positioning (Ranging / SLPositioning). Among them, ranging refers to determining the distance and / or direction between two or more UEs and / or the positioning of a UE (which may be called a "target UE") relative to another UE (which may be called a "reference UE") through a PC5 interface. Side link positioning refers to positioning the UE using the PC5 interface. Therefore, the UE's capability for ranging side link positioning is used to indicate whether the UE is allowed to perform distance measurement, direction measurement, or both.

[0051] Not all UEs need to support ranging sidelink positioning. Typically, a UE that supports ranging sidelink positioning will support ProSe and / or V2X.

[0052] In order to enable a UE supporting ranging sidelink positioning to perform the ranging sidelink positioning service, the network device is required to provide the UE with relevant configuration data, including policies and parameters related to the ranging sidelink positioning service.

[0053] Therefore, how to determine and provide the UE with configuration data for performing the ranging sidelink positioning service becomes an urgent problem to be solved.

[0054] In view of this, the present disclosure provides a method and device for determining a ranging sidelink positioning strategy. According to the technical solution provided by the present disclosure, the network device can determine a ranging sidelink positioning strategy for the UE for providing the configuration data required for the ranging sidelink 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 sidelink positioning service.

[0055] Figure 1 FIG. 1 is a flow chart of a method for determining a ranging sidelink positioning strategy according to an embodiment of the present disclosure.

[0061] In this embodiment, in the case of receiving capability information indicating that the UE at least supports ranging sidelink positioning from the AMF network element, the PCF network element can determine the ranging sidelink positioning strategy for the UE. Alternatively, in the case of receiving a UE policy container from the UE that at least includes a request to provide a ranging sidelink positioning strategy, the PCF network element can determine the ranging sidelink positioning strategy for the UE. Alternatively, in the case of receiving capability information indicating that the UE at least supports ranging sidelink positioning from the AMF network element and receiving a UE policy container from the UE that at least includes a request to provide a ranging sidelink positioning strategy, the PCF network element can determine the ranging sidelink positioning strategy for the UE.

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

[0063] The ranging sidelink positioning strategy includes configuration data for performing the ranging sidelink positioning service. Specifically, the ranging sidelink positioning strategy may include dedicated parameters and public parameters. Among them, the dedicated parameters are dedicated to performing the ranging sidelink positioning service.

[0064] According to the ranging sidelink positioning strategy determination method of the embodiment of the present invention, the PCF network element can determine the ranging sidelink 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, and the ranging sidelink positioning strategy includes configuration data for performing the ranging sidelink positioning service, thereby filling the technical gap in the prior art regarding how to determine and provide the UE with configuration data for performing the ranging sidelink positioning service.

[0065] Figure 2 FIG. 1 is a flow chart showing a method for determining a ranging sidelink positioning strategy according to an embodiment of the present disclosure. In this embodiment, the method is executed by a PCF network element, such as Figure 2 As shown, the ranging sidelink positioning strategy determination method includes the following steps:

[0072] Alternatively, configuration data for performing ranging sidelink positioning services, including required parameters and their values, may be stored in advance in the UDR network element. The PCF network element may obtain relevant configuration data from the UDR network element.

[0073] In this embodiment, in the case of receiving capability information indicating that the UE at least supports ranging sidelink positioning from the AMF network element, the PCF network element may determine the ranging sidelink positioning strategy for the UE based on the local policy of the PCF network element or the information received from the UDR network element. Alternatively, in the case of receiving a UE policy container from the UE that at least includes a request to provide a ranging sidelink positioning strategy, the PCF network element may determine the ranging sidelink positioning strategy for the UE based on the local policy of the PCF network element or the information received from the UDR network element. Alternatively, in the case of receiving capability information indicating that the UE at least supports ranging sidelink positioning and receiving a UE policy container from the UE that at least includes a request to provide a ranging sidelink positioning strategy, the PCF network element may determine the ranging sidelink positioning strategy for the UE based on the local policy of the PCF network element or the information received from the UDR network element.

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

Specifically, the ranging sidelink positioning strategy may include dedicated parameters and public parameters. Among them, the dedicated parameters are dedicated to performing the ranging sidelink positioning service. The public parameters can be used to perform both the ranging sidelink positioning service and the ProSe service, or both the ranging sidelink positioning service and the V2X service.

[0076] According to the ranging sidelink positioning strategy determination method of the embodiment of the present invention, 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 sidelink positioning strategy for the UE based on the PCF network element local policy or the information received from the UDR network element. The ranging sidelink positioning strategy includes configuration data for performing the ranging sidelink positioning service, thereby filling the technical gap in the prior art regarding how to determine and provide the UE with configuration data for performing the ranging sidelink positioning service.

[0077] exist Figure 1 Based on the illustrated embodiments, the present disclosure also provides multiple embodiments for determining ranging sidelink positioning strategies.

[0078] Figure 1 The policy-related information described in the illustrated embodiment may include different contents.

[0079] For example, policy-related information may include the following:

[0080] Case 1: the policy-related information includes capability information, and the capability information indicates that the UE supports ranging sidelink positioning and supports ProSe;

[0081] Case 2: The policy-related information includes capability information, and the capability information indicates that the UE supports ranging sidelink positioning and supports V2X;

[0082] Case 3: The policy-related information includes capability information, and the capability information indicates that the UE supports ranging sidelink positioning, ProSe, and V2X;

[0083] Case 4: the policy-related information includes a policy provision request, and the policy provision request includes a ranging sidelink positioning policy provision request and a ProSe policy provision request for requesting a ProSe policy;

[0084] Case 5: the policy-related information includes a policy provision request, and the policy provision request includes a ranging sidelink positioning policy provision request and a V2X policy provision request for requesting a V2X policy;

[0085] Case 6: the policy-related information includes a policy provision request, and the policy provision request includes a ranging sidelink positioning policy provision request, a ProSe policy provision request, and a V2X policy provision request;

[0086] Case 7: the policy-related information includes capability information and a policy provision request, and the capability information indicates that the UE supports ranging sidelink positioning and supports ProSe, and the policy provision request includes a ranging sidelink positioning policy provision request;

[0088] Case 9: The policy-related information includes capability information and a policy provision request, and the capability information indicates that the UE supports ranging sidelink positioning, ProSe and V2X, and the policy provision request includes a ranging sidelink positioning policy provision request.

[0089] Depending on the different contents included in the policy-related information, the ranging sidelink positioning policy for the UE may be determined by different embodiments. In the following embodiment shown, the ranging sidelink positioning policy may include dedicated parameters for the ranging sidelink positioning service and common parameters (also referred to as "shared parameters") for both the ranging sidelink positioning service and at least one of the ProSe service and the V2X service.

[0090] Figure 3 A flow chart of a method for determining a ranging sidelink positioning strategy 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 strategy related information in case 1, case 4, and case 7, such as Figure 3 As shown, the ranging sidelink positioning strategy determination method includes the following steps:

[0091] S301, determining dedicated parameters and corresponding parameter values ​​included in the ranging sidelink positioning strategy according to the PCF network element local strategy or information received from the UDR network element.

[0092] S302: Determine the parameters and their values ​​included in the ProSe policy for the UE as the common parameters and corresponding parameter values ​​included in the ranging sidelink positioning policy.

[0093] A local policy may be pre-configured for the PCF network element, and the PCF network element local policy may indicate configuration data for performing the ranging sidelink positioning service, and specifically, may indicate dedicated parameters and their values.

[0094] Alternatively, the configuration data for performing the ranging sidelink positioning service, including the dedicated parameters and their values, and the values ​​of various public parameters, may be stored in advance in the UDR network element. The PCF network element may obtain the relevant configuration data from the UDR network element.

[0095] The dedicated parameters are used exclusively for performing ranging sidelink positioning services. The public parameters can be used for performing both ranging sidelink positioning services and ProSe services, or for performing both ranging sidelink positioning services and V2X services.
