[0023] 1 shows a block diagram of a communication system provided by an exemplary embodiment of the present application, which may include a terminal 10, an access network device 20, and a core network device 30.

[0024] The number of terminals 10 is usually plural, and one or more terminals 10 may be distributed in a cell managed by each access network device 20. The terminals 10 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem having wireless communication capabilities, as well as various forms of user devices (User Equipment, UE), mobile stations (Mobile Stations, MS), etc. For ease of explanation, in the embodiments of the present application, the above-mentioned devices are collectively referred to as terminals.

[0025] The access network device 20 is a device deployed in an access network to provide a wireless communication function to the terminal 10. For ease of description, in the embodiment of the present application, the above devices for providing a wireless communication function to the terminal 10 are collectively referred to as network devices. A connection can be established between the network device 20 and the terminal 10 via an air interface for communication including signaling and data interaction. There may be more than one network device 20, and two adjacent network devices 20 may communicate with each other in a wired or wireless manner. The terminal 10 can switch between different network devices 20, i.e., can establish a connection with different network devices 20.

[0026] The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different radio access technologies, the name of the device with the network device function may be different. For example, in a 5G NR system, it is called gNodeB or gNB. As communication technology evolves, the name of the "network device" may change.

[0027] The core network device 30 is a device deployed in a core network, and the function of the core network device 30 is mainly to provide user connection, user management, and business execution bearer, and to provide an interface to an external network as a bearer network.

[0028] In some embodiments, the access network devices and core network devices mentioned above are collectively referred to as network devices, i.e., the terminal and the network devices perform data interaction.

[0029] 2 shows a flowchart of an information determining method provided by an exemplary embodiment of the present application, which is executed by a first device and includes the following steps: Step 102: The first device receives a service request sent by the second device.

[0030] Illustratively, the service request carries a service type of ranging / Sidelink (SL) positioning function.

[0031] In sidelink communication, there is a ranging / sidelink positioning function, which includes at least one of a ranging function and a sidelink positioning function, where the ranging function refers to determining the distance between any terminal and other terminals, or the direction and / or relative positioning of a target terminal and another reference terminal, and the sidelink positioning function refers to positioning a terminal via a sidelink to determine a geographical location where the terminal is located.

[0032] Optionally, the ranging / sidelink positioning functionality is realized via a direct connect communications interface (PC5 interface).

[0033] Taking the first device as an example being a first terminal, the first device performing a ranging / sidelink positioning function specifically refers to the first terminal determining the distance between itself and another terminal, or determining the direction and / or relative positioning with respect to the other terminal, and determining the geographical location where the first terminal is located via the sidelink.

[0034] Illustratively, the service type of the ranging / sidelink positioning function includes at least two; after the first device receives the service request sent by the second device, it can obtain the service type of the ranging / sidelink positioning function carried in the service request to determine policy parameters for performing the ranging / sidelink positioning function.

[0035] Optionally, the service type of the ranging / sidelink positioning function includes at least one of a Vehicle to Everything (V2X) service, a commercial service, and a public security service, where the V2X service can be considered as a first service, and the commercial service and / or the public security service can be considered as a second service.

[0036] Based on different service types, the policy parameters for performing the ranging / sidelink positioning function determined by the first device are different. For example, if the service type includes a first service, the first device performs a first policy parameter, and if the service type includes a second service, the first device performs a second policy parameter, and the second policy parameter is distinguished from the first policy parameter. Here, the policy parameters used for the ranging / sidelink positioning function include at least one of a policy used for the ranging / sidelink positioning function and a parameter used for the ranging / sidelink positioning function.

[0037] For example, if the service type of the ranging / sidelink positioning function is a V2X service, the policy parameters determined by the first device are V2X ranging / sidelink positioning policy parameters, or, for example, if the service type of the ranging / sidelink positioning function is a commercial service or a public security service, the policy parameters determined by the first device are Proximity Services (ProSe) ranging / sidelink positioning policy parameters.

[0038] Alternatively, the service request is a ranging / sidelink positioning service request. If the second device includes one of a second terminal, an application server, and a core network function, the ranging / sidelink positioning service request is sent in a ranging / sidelink positioning service process initiated by the corresponding second device. For example, the second device includes a second terminal, and the ranging / sidelink positioning service request is sent in a ranging / sidelink positioning service process initiated by the second terminal, or for example, the second device includes an application server, and the ranging / sidelink positioning service request is sent in a ranging / sidelink positioning service process initiated by the application server, or for example, the second device includes a core network function, and the ranging / sidelink positioning service request is sent in a ranging / sidelink positioning service process initiated by the core network function.

[0039] If the service request is a ranging / sidelink positioning service request, step 102 may realize the following steps: in a ranging / sidelink positioning service process initiated by the second device, the second device sends a ranging / sidelink positioning service request to the first device.

[0040] Step 104: The first device determines, based on the service type, policy parameters for performing ranging / sidelink positioning functions.

[0041] Different service types have different policy parameters for performing ranging / sidelink positioning functions.

[0042] Take the service type including a first service and a second service as an example, step 1041 can realize the following steps: If the service type includes a first service, the first device determines to execute a first policy parameter, and the first policy parameter is used to execute at least one operation of a ranging / sidelink positioning discovery operation and a service operation; If the service type includes a second service, the first device determines to execute a second policy parameter, and the second policy parameter is used to execute at least one operation of a ranging / sidelink positioning discovery operation and a service operation; The first policy parameter and the second policy parameter are different policy parameters.

[0043] Optionally, the first service includes a Vehicle-to-X (V2X) service, and the first policy parameters include V2X ranging / sidelink positioning policy parameters.

[0044] Optionally, the second service includes a commercial service and / or a public security service, and the second policy parameters include ProSe ranging / sidelink positioning policy parameters.

[0045] Here, if the service type includes a Vehicle-to-X (V2X) service, the first device forces the V2X ranging / sidelink positioning policy parameters, and if the service type includes a commercial service or a public security service, the first device forces the ProSe ranging / sidelink positioning policy parameters.

[0046] According to the above, the policy parameters for implementing ranging / sidelink positioning functions are affected by the service type. Taking the policy parameters as an example, dividing them into two categories, V2X ranging / sidelink positioning policy parameters and ProSe ranging / sidelink positioning policy parameters, the following lists different policy parameters:

[0047] Illustratively, the first device is a terminal, and the V2X ranging / sidelink positioning policy parameters include at least one of the following: (1) Permit Policy.

[0048] Here, in the case of the terminal's "E-UTRA (Evolved UMTS Terrestrial Radio Access Network) service" or "NR (New Radio) service", the authorization policy allows the terminal to perform at least one PLMN (Public Land Mobile Network) of V2X communication over the PC5 reference point. For each PLMN, the terminal is allowed to perform a RAT of V2X communication over the PC5 reference point.

[0049] For the terminal's "not served by E-UTRA" and "not served by NR", the authorization policy is whether to allow the UE to perform V2X communication over the PC5 reference point. The authorization policy further allows the RAT (Radio Access Network) that the terminal uses to perform V2X communication over the PC5 reference point.

[0050] (2) Radio parameters when the terminal is not served by NG-RAN (The interface between the gNB and the 5G CN- Radio Access Network).

[0051] The radio parameters include radio parameters and geographical regions for each PC5 RAT (i.e. LTE PC5, NR PC5) and an indication of whether each PC5 RAT is "operator managed" or "non-operator managed".

[0052] If the terminal can position in the corresponding geographical area, it shall perform V2X communication over the PC5 reference point using the radio parameters when the terminal is "not served by E-UTRA" and "not served by NR". If the terminal cannot position in the corresponding geographical area, it has no right to transmit.

[0053] (3) Policies / parameters for PC5 RAT selection and PC5 Tx profile selection.

[0054] (4) Policies or parameters relating to privacy information.

[0055] Here, the privacy information refers to information that has security assurance for the terminal, and prevents information leakage.

[0056] Here, policies or parameters related to privacy information include: 1.1. List of V2X service types in geographic areas where privacy support is required.

[0057] 1.2, the privacy information timer value indicates the duration of the second layer ID change for each source assigned by the terminal when privacy protection is required.

[0058] (5) Policy or parameters when selecting LTE PC5.

[0059] (6) Policy or parameter when selecting NR PC5.

[0060] Wherein, the policy or parameter when selecting NR PC5 includes at least one of the following: 1.1. Map V2X service types to V2X frequencies with geographical regions.

[0061] 1.2. Mapping from V2X service type to default communication mode (i.e. broadcast mode, multicast mode or unicast mode).

[0062] 1.3. Mapping from V2X service type to target layer 2 ID, broadcasting the mapping relationship.

[0063] 1.4, Mapping from V2X service type to target Layer 2 ID for multicast mode communication.

[0064] 1.5. Mapping from V2X service type to default target Layer 2 ID, which is used to establish a unicast connection via initial signaling.

[0065] (7) A validity timer indicating the expiration time of a V2X policy or parameter.

[0066] The validity timer indicates the expiration time of the V2X policy or parameter, i.e., when the timing of the validity timer is reached, the V2X policy or parameter becomes invalid.

[0067] Illustratively, the ProSe ranging / sidelink positioning policy parameters include two aspects of parameter information, where one aspect is directly discovered parameter information and another aspect is directly connected communication parameter information.

[0068] Take the first device as an example, and the directly discovered parameter information includes at least one of the following: (1) Permit Policy.

[0069] The following explains the permission policy in two cases: First type: When the terminal is in "NG-RAN service", the authorization policy opens the 5G ProSe direct discovery Model A monitoring authorization policy, and the terminal is authorized for PLMNs that perform 5G ProSe direct discovery monitoring.

[0070] Or, if the terminal is in "NG-RAN service", the authorization policy opens the 5G ProSe direct discovery Model A monitoring authorization policy, and the UE is authorized to broadcast PLMNs.

[0071] Second type: Limited 5G ProSe direct discovery, including: Restricted 5G ProSe direct discovery Model A (Mode A) monitoring authorization policy: PLMNs in which the terminal performs restricted 5G ProSe direct discovery Model A monitoring are permitted.

[0072] Or, restricted 5G ProSe direct discovery Model A declaration permission policy: PLMNs in which the terminal performs restricted 5G ProSe direct discovery Model A declaration are permitted.

[0073] Or, restricted 5G ProSe direct discovery Model B (Mode B) discoverer operation permission policy: PLMNs in which the terminal performs Model B discoverer operation are permitted.

[0074] Or, restricted 5G ProSe direct discovery Model B discovery operation authorization policy: PLMNs in which authorized terminals perform Model B discoverer operation are authorized.

[0075] (2) Parameters for 5G ProSe direct discovery.

[0076] Mapping from ProSe service to target layer 2 ID, this mapping relationship is used to send / receive initial signaling of discovery messages.

[0077] In some embodiments, the ProSe service is represented using a ProSe identifier.

[0078] (3) Radio parameters when the terminal is not served by NG-RAN.

[0079] The radio parameters include the radio parameters and geographical area of ​​each NR PC5, and an indication of whether each NR PC5 is "operator managed" or "non-operator managed". If the terminal can position in the corresponding geographical area, the terminal performs 5G ProSe direct discovery on the PC5 reference point using the radio parameters when "not served by NG-RAN". Otherwise, the terminal has no right to transmit.

[0080] (4) Terminal identity of restricted directly discovered restricted ProSe discovery.

[0081] (5)) Group member discovery parameters.

[0082] wherein the group member discovery parameters include at least one of the following: 1.1. Application layer group ID: identifies the application layer group or discovery group to which the terminal belongs; 1.2, Layer-2 Group ID: Layer-2 ID represents the application layer group ID; 1.3. User information ID: for module A, this corresponds to the user information parameters when the terminal notifies the UE. For module B, when the terminal is a discoverer or a discoverer terminal, this corresponds to the discoverer information in the request message and the discoverer information in the response message.

[0083] (6) A validity timer indicating the expiration time of the 5G ProSe direct discovery policy / parameters.

[0084] The validity timer indicates the expiration time of the 5G ProSe direct discovery policy / parameters, that is, when the validity timer reaches its timing, the 5G ProSe direct discovery policy / parameters become invalid.

[0085] Take the first device as an example, and the parameter information of the direct connection communication discovery includes at least one of the following: (1) Permission Policy: If the terminal is "served by NG-RAN", the terminal allows the PLMN to perform 5G ProSe direct connection communication over the PC5 reference point.

[0086] If the terminal is "not served by NG-RAN", the terminal is not permitted to perform 5G ProSe direct connection communications on the PC5 reference point.

[0087] (2) Multicast mode 5G ProSe direct connection communication policies / parameters.

[0088] Wherein, the multicast mode 5G ProSe direct connection communication policies / parameters include: 1.1, for each supported application layer group, parameters to perform multicast mode 5G ProSe direct connection communication when the terminal is provided by the PCF, provided by the ME, or configured by the UICC.

[0089] 1.2. Application Layer Group ID: Identifies the application layer group to which the terminal belongs.

[0090] 1.3. ProSe Layer 2 Group ID: The target Layer 2 ID is valid when the application layer group ID is provided by the application layer.

[0091] 1.4, ProSe group IP multicast address.

[0092] 1.5. Indicate whether the terminal uses IPv4 (Internet Protocol version 4) or IPv6 (Internet Protocol version 6).

[0093] 1.6, For a particular group configured to use IPv4 operation, an IPv4 address shall be used as the source address by the terminal. If not provided, the terminal shall obtain a link-local address for the group using dynamic configuration of an IPv4 link-local address.

[0094] (3) Radio parameters when the terminal is not served by NG-RAN.

[0095] The radio parameters include the radio parameters and geographical area of ​​each NR PC5, and an indication of whether each NR PC5 is "operator managed" or "non-operator managed". If the terminal can position in the corresponding geographical area, the terminal uses the radio parameters to perform 5G ProSe direct connection communication over the PC5 reference point when the terminal is "not served by non-NG-RAN". Otherwise, the terminal has no right to transmit.

[0096] (4) Policies or parameters relating to privacy information.

[0097] 1.1. List of ProSe service types for geographic areas where privacy support is required.

[0098] 1.2, the privacy information timer value indicates the duration of the second layer ID change for each source assigned by the terminal when privacy protection is required.

[0104] (6) Routing selection policy.

[0105] (7) A validity timer indicating the expiration time of 5G ProSe direct connection communication policies / parameters.

[0106] The validity timer indicates the expiration time of the 5G ProSe direct connection communication policy / parameter, that is, when the timing time of the validity timer is reached, the 5G ProSe direct connection communication policy / parameter becomes invalid.

[0107] As described above, the information determining and transmitting method provided by the embodiment of the present application provides a solution of what policy parameters are used for ranging / sidelink positioning functions in different service types, where a service type is carried in a service request sent from a second device to a first device, and after the first device receives the service request, the first device can determine policy parameters for performing ranging / sidelink positioning functions based on the service type carried in the service request.

[0108] Alternatively, if the service type includes a V2X service, the first device decides to implement the V2X ranging / sidelink positioning policy parameters, and if the service type includes a commercial service and / or a public security service, the first device decides to implement the ProSe ranging / sidelink positioning policy parameters.

[0109] In an alternative implementation scenario, the communication system includes a first device, a second device, and a third device, where the first device and the third device are devices performing two different ranging / sidelink positioning functions, respectively, and the first device and the third device perform similar steps in information determination and transmission. Exemplarily, the third device receives a service request sent by the first device, and the service request carries a service type of the ranging / sidelink positioning function received by the first device from the second device. For example, the first device is a first terminal, the third device is a second terminal, and each of the first terminal and the second terminal is a terminal performing two different ranging / sidelink positioning functions.

[0110] 3 shows a flowchart of an information determining and transmitting method provided by an exemplary embodiment of the present application, where the information determining method is performed by a first device and a third device, and the information transmitting method is performed by a second device, the method including the following steps: Step 202: The second device sends a service request to the first device.

[0111] Exemplarily, the service request carries a service type for ranging / sidelink positioning function, which is used to determine policy parameters for performing the ranging / sidelink positioning function on the first device and the third device.

[0112] Here, the relevant description of the ranging / sidelink positioning function may refer to the content of step 102, which will be omitted here. Taking the first device as an example where the first device is a first terminal and the third device is a third terminal, the first device performing the ranging / sidelink positioning function specifically refers to the first terminal determining the distance between the first terminal and the third terminal, or determining the direction and / or relative positioning with the third terminal, and determining the geographical position where the first terminal is located via the sidelink.

[0113] Illustratively, the service type of the ranging / sidelink positioning function includes at least two; after the first device receives the service request sent by the second device and the third device receives the service request sent by the first device, the first device and the third device can obtain the service type of the ranging / sidelink positioning function carried in the service request to determine policy parameters for performing the ranging / sidelink positioning function.

[0114] Optionally, the service type of the ranging / sidelink positioning function includes at least one of a Vehicle to Everything (V2X) service, a commercial service, and a public security service, where the V2X service can be considered as a first service, and the commercial service and / or the public security service can be considered as a second service.

[0115] Based on different service types, the policy parameters for performing the ranging / sidelink positioning function determined by the first device and the third device are different. For example, when the service type includes a first service, the first device and the third device execute a first policy parameter, and when the service type includes a second service, the first device and the third device execute a second policy parameter, and the second policy parameter is differentiated from the first policy parameter. Here, the policy parameters used for the ranging / sidelink positioning function include at least one of a policy used for the ranging / sidelink positioning function and a parameter used for the ranging / sidelink positioning function.

[0116] For example, if the service type of the ranging / sidelink positioning function is a V2X service, the policy parameters determined by the first device and the third device are V2X ranging / sidelink positioning policy parameters, or, for example, if the service type of the ranging / sidelink positioning function is a commercial service or a public security service, the policy parameters determined by the first device and the third device are Proximity Services (ProSe) ranging / sidelink positioning policy parameters.

[0117] Alternatively, the service request is a ranging / sidelink positioning service request. If the second device includes one of a second terminal, an application server, and a core network function, the ranging / sidelink positioning service request is sent in a ranging / sidelink positioning service process initiated by the corresponding second device.

[0118] If the service request is a ranging / sidelink positioning service request, step 202 may realize the following steps: in a ranging / sidelink positioning service process initiated by the second device, the second device sends a ranging / sidelink positioning service request to the first device.

[0119] Alternatively, the second device may include one of a second terminal, an application server, and a core network function. For example, the second device may include a second terminal, or the second device may include an application function (AF), or the second device may include a 5G core network function (5GC NF).

[0120] Depending on the second device, the service request may be transmitted through different network elements.

[0121] Alternatively, the second device may include a second terminal, and step 201 may realize a step of the second terminal sending a service request to the first device via the AMF.

[0122] Here, when the first device includes a first terminal, the first terminal corresponds to the first AMF, and the second terminal corresponds to the second AMF, the process of sending a service request is specifically as follows: the second terminal sends a service request to the second AMF, the second AMF sends a service request to the first AMF, and the first AMF sends a service request to the first terminal.

[0123] Alternatively, the second device may include an AF, and step 201 may realize a step of the second terminal sending a service request to the first device via a Network Exposure Function (NEF).

[0124] Here, when the first device includes a first terminal and the first terminal corresponds to the first AMF, the process of sending a service request specifically includes: the AF sending a service request to the NEF, the NEF sending a service request to the first AMF, and the first AMF sending a service request to the first terminal.

[0125] Step 203: The first device receives a service request sent by the second device.

[0126] Exemplarily, the service request carries a service type for the ranging / sidelink positioning function, which is used by the first device to determine policy parameters to be used for the ranging / sidelink positioning function.

[0127] Here, the relevant explanation of the service type and policy parameters can be referred to above, and will not be repeated here.

[0128] Step 204: The first device sends a service request to the third device.

[0129] Exemplarily, the service request carries a service type for the ranging / sidelink positioning function received by the first device from the second device, and the service type is used by the third device to determine policy parameters to be used for the ranging / sidelink positioning function.

[0130] Here, the relevant explanation of the service type and policy parameters can be referred to above, and will not be repeated here.

[0131] Step 205: The third device receives the service request sent by the first device.

[0132] Exemplarily, the service request carries a service type for the ranging / sidelink positioning function received by the first device from the second device, and the service type is used by the third device to determine policy parameters to be used for the ranging / sidelink positioning function.

[0133] Here, the relevant explanation of the service type and policy parameters can be referred to above, and will not be repeated here.

[0134] Step 2061: The first device determines, based on a service type, policy parameters for performing ranging / sidelink positioning functions.

[0135] Different service types have different policy parameters for performing ranging / sidelink positioning functions.

[0136] For example, the service type includes a first service and a second service. Step 2061 includes: If the service type includes a first service, determining that the first device executes a first policy parameter, the first policy parameter being used to execute at least one operation of a ranging / sidelink positioning discovery operation and a service operation; and if the service type includes a second service, determining that the first device executes a second policy parameter, the second policy parameter being used to execute at least one of a ranging / sidelink positioning discovery operation and a service operation; The first policy parameter and the second policy parameter are different policy parameters.

[0137] Optionally, the first service includes a Vehicle-to-X (V2X) service, and the first policy parameters include V2X ranging / sidelink positioning policy parameters.

[0138] Optionally, the second service includes a commercial service and / or a public security service, and the second policy parameters include ProSe ranging / sidelink positioning policy parameters.

[0139] Here, if the service type includes a Vehicle-to-X (V2X) service, the first device forces the V2X ranging / sidelink positioning policy parameters, and if the service type includes a commercial service or a public security service, the first device forces the ProSe ranging / sidelink positioning policy parameters.

[0140] According to the above, the policy parameters for performing ranging / sidelink positioning functions are affected by the service type. For example, the third device is a terminal, and the policy parameters are divided into two policy parameters, namely, V2X ranging / sidelink positioning policy parameters and ProSe ranging / sidelink positioning policy parameters. Different policy parameters may refer to the parameter information listed in step 104, which is omitted here.

[0141] Step 2062: The third device determines, based on the service type, policy parameters for performing ranging / sidelink positioning functions.

[0142] Different service types have different policy parameters for performing ranging / sidelink positioning functions.

[0143] For example, the service type includes a first service and a second service. Step 2062 includes: if the service type includes a first service, determining that the third device executes a first policy parameter, the first policy parameter being used to execute at least one operation of a ranging / sidelink positioning discovery operation and a service operation; and if the service type includes a second service, determining that the third device executes a second policy parameter, the second policy parameter being used to execute at least one operation of a ranging / sidelink positioning discovery operation and a service operation; The first policy parameter and the second policy parameter are different policy parameters.

[0144] Optionally, the first service includes a Vehicle-to-X (V2X) service, and the first policy parameters include V2X ranging / sidelink positioning policy parameters.

[0145] Optionally, the second service includes a commercial service and / or a public security service, and the second policy parameters include ProSe ranging / sidelink positioning policy parameters.

[0146] According to the above, the policy parameters for performing ranging / sidelink positioning functions are affected by the service type. For example, the third device is a terminal, and the policy parameters are divided into two policy parameters, namely, V2X ranging / sidelink positioning policy parameters and ProSe ranging / sidelink positioning policy parameters. Different policy parameters may refer to the parameter information listed in step 104, which is omitted here.

[0148] Alternatively, if the service type includes a V2X service, the first device and the third device decide to implement V2X ranging / sidelink positioning policy parameters, and if the service type includes a commercial service and / or a public security service, the first device and the third device decide to implement ProSe ranging / sidelink positioning policy parameters.

For different service types, the first terminal and the third terminal can use different behaviors to support the ranging / sidelink positioning function.

[0164] Take for example that the second device is a Policy Control Function (PCF). The PCF determines service authorization policy / parameter on the use of Ranging / SL positioning for V2X or for ProSe services and provisions them to the UE. Here, the terminals include a first terminal and a third terminal.

[0165] Exemplarily, the PCF V2X and ProSe provide two different ranging / sidelink positioning policy parameters: -The Ranging / SL positioning policy / parameter of V2X applies to Ranging / SL positioning used for V2X service applications. -The Ranging / SL positioning policy / parameter of ProSe applies to Ranging / SL positioning used for commercial and public safety service applications.

[0166] Exemplarily, after the first terminal receives a service request sent by the second device and the third terminal receives the service request sent by the first terminal, the first terminal and the third terminal may determine ranging / sidelink positioning policy parameters applying V2X or ranging / sidelink positioning policy parameters applying ProSe based on the service type carried in the service request.

[0167] Optionally, the determining of policy parameters for performing ranging / sidelink positioning functions used by the first terminal and the third terminal may realize the following steps: -If the ranging / sidelink positioning service type is V2X service, the Ranging / SL positioning policy / parameter of V2X is enforced for the Ranging / SL positioning discovery and service operation, -If Ranging / SL positioning service type is commercial service or public safety service, the Ranging / SL positioning policy / parameter of ProSe is enforced for the Ranging / SL positioning discovery and service operation.
