[0051] The embodiments of the disclosure are described in detail below, examples of which are shown in the accompanying drawings, in which the same or similar reference numerals represent the same or similar elements throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0052] In the ranging method provided by the embodiments of the disclosure, a ranging terminal device UE receives a ranging service request sent by a ranging initiating UE, wherein the ranging service request comprises an identifier and ranging parameters; the ranging UE determines a ranging role of the ranging UE according to the identifier in the ranging service request, the ranging role comprising an observer UE or a target UE, and the ranging UE performs ranging according to the ranging parameters and the ranging role. It can be known that, in the embodiments of the disclosure, direct discovery can be performed between two UEs to be ranged based on the identifier in the ranging service request, so that the ranging UE among the two UEs to be ranged can automatically perform ranging, thereby improving ranging efficiency and accuracy, reducing power consumption, and improving user experience.

[0053] The ranging method, apparatus, UE and storage medium provided by the disclosure are described in detail below with reference to the accompanying drawings.

[0054] Figure 1 A flowchart of a ranging method provided by the embodiments of the disclosure is applied to a ranging UE, as shown in Figure 1 The ranging method can comprise the following steps:

[0055] In step 101, a ranging UE (User Equipment, terminal device) receives a ranging service request sent by a ranging initiating UE, wherein the ranging service request comprises an identifier and ranging parameters.

[0056] It should be noted that the ranging method of the embodiments of the present disclosure can be applied in any UE. The UE can refer to a device that provides voice and / or data connectivity for a user. The UE can communicate with one or more core networks via a RAN (Radio Access Network), and the UE can be an IoT terminal such as a sensor device, a mobile phone (or called "cellular" phone), and a computer with an IoT terminal, for example, which can be a fixed, portable, pocket, handheld, computer-embedded, or vehicle-mounted device. For example, a station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, or a user agent. Alternatively, the UE can also be a device of an unmanned aerial vehicle. Alternatively, the UE can also be a vehicle-mounted device, for example, it can be a vehicle-mounted computer with wireless communication function, or a wireless terminal externally connected to the vehicle-mounted computer. Alternatively, the UE can also be a roadside device, for example, it can be a street lamp, a signal lamp, or other roadside devices with wireless communication function, etc.

[0057] The ranging parameters can include ranging content (such as a distance value between the observing UE and the target UE, an angle value, a direction of the target UE to the observing UE, etc.), QoS (Quality of Service) requirements, and reporting periodicity, etc. In an embodiment of the present disclosure, the identification of the ranging service request can include the identification of the observing UE and the identification of the target UE, wherein the observing UE can be a UE used to perform the ranging operation, and the observing UE is used to range the target UE. In an embodiment of the present disclosure, the observing UE can range the target UE based on the ranging parameters to generate a ranging result. Of course, in other embodiments of the present disclosure, the identification of the ranging service request can only include the identification of the observing UE or the identification of the target UE. For example, if the ranging service request is only sent to the observing UE, the identification of the ranging service request can only include the identification of the target UE, so that the observing UE can determine the target UE according to the identification of the target UE.

[0058] As an example, Figure 2 A structural diagram of relative positions of an observing UE and a target UE provided by an embodiment of the present disclosure is shown in FIG. 1. As shown in FIG. 1, the observing UE 100 and the target UE 200 are in a relative position relationship. The observing UE 100 can be used to perform ranging on the target UE 200, and the observing UE 100 can be a UE used to perform the ranging operation. The target UE 200 can be a UE to be ranged by the observing UE 100. The observing UE 100 can be a UE used to perform the ranging operation, and the observing UE 100 can be used to range the target UE 200. Figure 2As shown, the observing UE has a reference plane and a reference direction. And, the direction from the target UE to the observing UE can be a direction from the line connecting the observing UE and the target UE to the reference direction, that is, Figure 2 As shown, the direction A. Wherein, the direction from the target UE to the observing UE can be represented by the azimuth direction and the elevation direction of the target UE, the reference Figure 2 As can be seen, the azimuth direction of the target UE is the angle from the reference direction to the line formed between the line from the observer UE to the target UE and the line projected on the same plane as the reference direction orthogonal to the zenith. And, the target UE also has an elevation direction, which is the direction from the horizontal plane to the line connecting the observing UE and the target UE.

[0059] Then, the observing UE can measure the distance to the target UE by measuring Figure 2 As shown, the distance between the target UE and the observing UE and the direction from the target UE to the observing UE can achieve ranging of the target UE. And, the ranging service can be carried out whether there is 5G coverage or not.

[0060] Further, in one embodiment of the present disclosure, the ranging initiating UE can be the observing UE. In another embodiment of the present disclosure, the ranging initiating UE can be the target UE. In still another embodiment of the present disclosure, the ranging initiating UE can not be any of the target UE and the observing UE.

[0061] And, Figure 3 An architecture diagram of a ranging service provided by an embodiment of the present disclosure is shown in FIG. 1. Figure 3 As shown, the ranging service architecture includes an observing UE A, a target UE B and a ranging initiating UE (not shown in the figure). Wherein, the observing UE A can perform ranging on the target UE B based on the ranging service request sent by the ranging initiating UE. It should be noted that the interaction between the observing UE A and the target UE B can be implemented based on the AMF (Access and Mobility Management Function) in the 3GPP control plane. Similarly, the interaction between the observing UE A and the ranging initiating UE and the interaction between the target UE B and the ranging initiating UE can also be implemented based on the AMF in the 3GPP control plane.

[0062] In step 102, the ranging UE determines the ranging role of the ranging UE according to the identifier in the ranging service request, the ranging role including the observing UE or the target UE.

[0063] As a possible implementation form, the method that the ranging UE determines the ranging role of the ranging UE according to the identifier in the ranging service request can include:

[0064] If the identity of the ranging UE is consistent with the identity of the observing UE, the ranging role of the ranging UE is determined as the observing UE; if the identity of the ranging UE is consistent with the identity of the target UE, the ranging role of the ranging UE is determined as the target UE.

[0065] In step 103, the ranging UE performs ranging according to the ranging parameter and the ranging role.

[0066] The ranging method provided by the embodiment of the present disclosure can enable the two UEs to be directly discovered based on the identity in the ranging service request, so that the ranging UE among the two UEs to be ranged can automatically perform ranging, thereby improving ranging efficiency and accuracy, reducing power consumption, and improving user experience.

[0067] Figure 4 The flowchart of the ranging method provided by another embodiment of the present disclosure is applied to a ranging UE, as shown in FIG. 4, the method can include: Figure 4

[0068] In step 401, the ranging UE and the ranging initiating UE are authenticated for ranging service, wherein the ranging UE and the ranging initiating UE are different UEs, and there is a direct communication connection between the ranging UE and the ranging initiating UE.

[0069] As a possible implementation form, the ranging service authentication of the ranging UE and the ranging initiating UE can include authorization of the ranging service of the ranging UE and the ranging initiating UE, and specifically can include mutual discovery of the two UEs to be ranged, privacy, or specification of ranging service policy or ranging parameter.

[0070] In step 402, the ranging UE receives a ranging service request sent by the ranging initiating UE, wherein the ranging service request includes an identity and a ranging parameter.

[0071] As a possible implementation form, based on the direct communication connection between the ranging UE and the ranging initiating UE, the ranging initiating UE can discover the ranging UE in a direct communication manner and send the ranging service request to the ranging UE.

[0072] In step 403, the ranging UE determines the ranging role of the ranging UE as the observing UE according to the identity in the ranging service request.

[0073] ​In a possible implementation form, the ranging UE is the observing UE, and the ranging initiation UE is the target UE. In another possible implementation form, the ranging UE is the observing UE, and the ranging initiation UE is neither the observing UE nor the target UE.

[0074] At step 404, the ranging UE determines the target UE according to the identifier of the target UE.

[0075] As a possible implementation form, the ranging UE can broadcast the identifier of the target UE, so that each UE receives the identifier of the target UE and compares its own identifier with the identifier of the target UE. When the identifier of a certain UE is consistent with the identifier of the target UE, it is determined that the certain UE is the target UE. The target UE can feed back a notification information to the ranging UE, so that the ranging UE determines the target UE based on the notification information.

[0076] At step 405, the ranging UE performs ranging on the target UE according to the ranging parameter.

[0077] As a possible implementation form, the ranging UE can perform ranging on the target UE by determining the distance, angle, and direction of the target UE from the ranging UE.

[0078] At step 406, the ranging UE generates a ranging result and feeds back the ranging result to the ranging initiation UE.

[0079] As a possible implementation form, the ranging UE can directly send the ranging result to the ranging initiation UE based on the communication connection between the ranging UE and the ranging initiation UE.

[0080] The ranging method provided by the embodiments of the present disclosure can enable the observing UE to directly receive the ranging service request including the identifier and the ranging parameter sent by the ranging initiation UE, and determine the target UE according to the identifier in the ranging service request, so that the observing UE can perform ranging on the target UE according to the ranging parameter to generate a ranging result and feed back the ranging result to the ranging initiation UE. Thus, the ranging service request and the ranging result can be directly exchanged between the observing UE and the ranging initiation UE in the embodiments of the present disclosure, so that the ranging service can be started based on the interaction between the UEs, thereby ensuring the automation of the ranging method, improving the ranging efficiency and accuracy, reducing the power consumption, and improving the user experience.

[0081] Figure 5 FIG. 4 is a flowchart of a ranging method provided by another embodiment of the present disclosure, applied to a ranging UE, which can include the following steps. Figure 5 As shown in FIG. 4, the method can include the following steps.

[0082] In step 501, a ranging service authentication is performed between a ranging UE and a ranging initiating UE, wherein the ranging UE and the ranging initiating UE are different UEs, and there is a direct communication connection between the ranging UE and the ranging initiating UE.

[0083] In step 502, the ranging UE receives a ranging service request sent by the ranging initiating UE, wherein the ranging service request comprises an identifier and a ranging parameter.

[0084] In step 503, the ranging UE determines, according to the identifier in the ranging service request, that the ranging role of the ranging UE is a target UE.

[0085] In one possible implementation form, the ranging UE is the target UE, and the ranging initiating UE is an observer UE. In another possible implementation form, the ranging UE is the target UE, and the ranging initiating UE is neither the observer UE nor the target UE.

[0086] In step 504, the ranging UE determines an observer UE according to an identifier of the observer UE.

[0087] As one possible implementation form, the ranging UE can broadcast the identifier of the observer UE, so that each UE receives the identifier of the observer UE and compares its own identifier with the identifier of the observer UE. When the identifier of a certain UE is consistent with the identifier of the observer UE, the certain UE is determined as the observer UE. The observer UE can feed back a notification information to the ranging UE, so that the ranging UE determines the observer UE based on the notification information.

[0088] In step 505, the ranging UE sends the ranging parameter to the observer UE, so that the observer UE performs ranging on the ranging UE according to the ranging parameter.

[0089] In one possible implementation form, after the observer UE completes the ranging on the ranging UE and generates a ranging result, the observer UE directly feeds back the ranging result to the ranging initiating UE.

[0090] In another possible implementation form, after the observer UE completes the ranging on the ranging UE and generates a ranging result, the observer UE feeds back the ranging result to the ranging UE, so that the ranging UE forwards the ranging result to the ranging initiating UE.

[0091] The ranging method provided in this embodiment allows the target UE to receive a ranging service request, including an identifier and ranging parameters, sent by the ranging initiating UE. The target UE identifies the observing UE based on the identifier in the ranging service request and sends the ranging parameters to the observing UE, enabling the observing UE to measure the distance to the ranging UE based on the ranging parameters. Thus, the target UE and the ranging initiating UE exchange ranging service requests and ranging results, enabling the ranging service to be initiated based on UE interaction. This ensures the automation of the ranging method, improves ranging efficiency and accuracy, reduces power consumption, and enhances the user experience.

This ensures the automation of the ranging method, improves ranging efficiency and accuracy, reduces power consumption, and enhances the user experience.

It can be known that Figure 3 It can be known that the core network device AMF is essentially located in the 3GPP control plane.

Thus, in the embodiments of the present disclosure, the target UE and the ranging initiation UE can exchange a ranging service request and a ranging result in a 3GPP control plane, that is, the ranging service can be started based on the 3GPP control plane, thereby ensuring the automation of the ranging method, and ensuring a low-delay ranging service, improving the ranging efficiency and accuracy, reducing power consumption, and improving user experience.

[0160] ​The second AMF queries the UDM based on the identifier of the observed UE and the identifier of the target UE. If the second AMF finds an AMF serving the observed UE, the second AMF identifies the observed UE as the ranging UE and designates the AMF serving the observed UE as the first AMF. If the second AMF finds an AMF serving the target UE, the second AMF identifies the target UE as the ranging UE and designates the AMF serving the target UE as the first AMF. If the second AMF finds both an AMF serving the target UE and an AMF serving the observed UE, the second AMF identifies either the target UE or the ranging UE as the ranging UE and designates the AMF serving the ranging UE as the first AMF (i.e., any one of the AMFs serving the observed UE and the AMF serving the target UE).

[0161] Step 1503: The second AMF sends the ranging service request to the ranging UE through the first AMF.

[0162] Additionally, as an optional implementation, after step 1503, the method further includes: the second AMF receiving the ranging result sent by the ranging UE through the first AMF; and the second AMF sending the ranging result to the ranging initiating UE.
