For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, for example, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0045] The application scenarios of this application will be described below:

[0046] Figure 1A block diagram of a communication system provided in an exemplary embodiment of this application is shown. The communication system may include: a terminal 10, an access network device 20, and a core network device 30.

[0047] The number of terminals 10 is typically multiple, with one or more terminals 10 distributed within the cell managed by each access network device 20. Terminals 10 may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile station (MS), etc. For ease of description, in this embodiment, the devices mentioned above are collectively referred to as terminals.

[0048] Access network device 20 is a device deployed in an access network to provide wireless communication functionality to terminal 10. For ease of description, in this embodiment, the aforementioned device providing wireless communication functionality to terminal 10 is collectively referred to as a network device. Network device 20 and terminal 10 can establish a connection via an air interface, thereby communicating through this connection, including signaling and data exchange. There can be multiple network devices 20, and two adjacent network devices 20 can communicate via wired or wireless means. Terminal 10 can switch between different network devices 20, that is, establish connections with different network devices 20.

[0049] The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems employing different wireless access technologies, the name of the device with network equipment functions may differ; for example, in a 5G NR system, it is called gNodeB or gNB. As communication technologies evolve, the name "network device" may change.

[0050] Core network equipment 30 is deployed in the core network. Its main functions are to provide user connectivity, manage users, and carry services, serving as an interface to external networks. Core network equipment 30 includes various core network elements with different management functions. These elements include AMF (Access and Mobility Management Function), SMF (Session Management Function), PCF (Policy Control Function), UPF (User Plane Function), NSSF (Network Slice Selection Function), AUSF (Authentication Server Function), UDM (Unified Data Management), and AF (Application Function), among others.

[0051] In some embodiments, the access network devices and core network devices mentioned above are collectively referred to as network devices, meaning that the terminal interacts with the network devices.

[0052] Figure 2 The flowchart illustrates a parameter configuration method provided in an exemplary embodiment of this application, which can be applied to, for example, Figure 1 In the terminal and network device shown, the method includes at least some of the following:

[0053] Step 201: The network device sends first parameter information to the terminal. The first parameter information is used by the terminal to perform ranging or lateral link positioning. The first parameter information belongs to at least one of multiple second parameter information in V2X (Vehicle to X) service, and / or the first parameter information belongs to at least one of multiple third parameter information in ProSe (Proximity Services) service.

[0054] In the embodiments of this application, the terminal has at least one of ranging function or lateral link positioning function. That is, for the terminal, the terminal can perform ranging, or the terminal can perform lateral link positioning, or the terminal can perform both ranging and lateral link positioning.

[0055] Before performing ranging or lateral link positioning, the terminal needs to obtain first parameter information for ranging or lateral link positioning. Then, the terminal performs ranging or lateral link positioning based on the first parameter information. The network device then sends the first parameter information to the terminal.

[0056] The ranging function refers to any terminal determining the relative distance between itself and multiple other terminals, or determining the direction and / or relative positioning of a target terminal relative to another reference terminal. The positioning function refers to locating the terminal to determine its geographical location.

[0057] Step 202: The terminal receives first parameter information sent by the network device. The first parameter information is used by the terminal to perform ranging or side-link positioning. The first parameter information belongs to at least one of multiple second parameter information in the V2X service, and / or the first parameter information belongs to at least one of multiple third parameter information in the ProSe service.

[0058] For the terminal, after the network device sends the first parameter information to the terminal, the terminal can receive the first parameter information sent by the network device and determine the first parameter information for ranging or lateral link positioning.

[0059] For example, the first parameter information mentioned above includes three cases:

[0060] (1) The first parameter information belongs to at least one of the multiple second parameter information in the V2X service.

[0061] (2) The first parameter information belongs to at least one of the multiple third parameter information in the ProSe service.

[0062] (3) The first parameter information belongs to at least one of the multiple second parameter information in the V2X service, and the first parameter information also belongs to at least one of the multiple third parameter information in the ProSe service.

[0063] In the embodiments of this application, when the first parameter information belongs to at least one of the multiple second parameter information in the V2X service and also belongs to at least one of the multiple third parameter information in the ProSe service, the first parameter information is actually divided into two parts: one part is the first parameter information corresponding to the second parameter information of the V2X service, and the other part is the first parameter information corresponding to the third parameter information of the ProSe service.

[0064] It should be noted that the embodiments in this application are only illustrated by the example where the first parameter information belongs to at least one of the second parameter information in the V2X service, and / or the first parameter information belongs to at least one of the third parameter information in the ProSe service. In another embodiment, the first parameter information used by the terminal for ranging or lateral link positioning is shared with the second parameter information in the V2X service, and / or the first parameter information is shared with the third parameter information in the ProSe service. Alternatively, the first parameter information used by the terminal for ranging or lateral link positioning is obtained from the second parameter information in the V2X service, and / or the first parameter information is obtained from the third parameter information in the ProSe service.

[0065] In some embodiments, the first parameter information sent by the network device is actually parameter information belonging to the V2X service and / or ProSe service. If the terminal needs to obtain the first parameter information from the V2X service and / or ProSe service, the terminal needs to have V2X capability and / or ProSe capability.

[0066] When the terminal has V2X capability, it can determine the first parameter information from the second parameter information in the V2X service. When the terminal has ProSe capability, it can determine the first parameter information from the third parameter information in the ProSe service. In other words, the terminal supports service types including any one of the following three cases:

[0067] (1) The terminal has V2X capability.

[0068] (2) The terminal has ProSe capability.

[0069] (3) The terminal has V2X and ProSe capabilities.

[0070] In this embodiment, the terminal has V2X capability and / or ProSe capability, and can thus determine the first parameter information from the parameter information in the V2X service and / or ProSe service.

[0071] It should be noted that the steps performed by the network device can form a separate embodiment, and the steps performed by the terminal can also form a separate embodiment; this application does not limit this.

[0072] In the solution provided in this application embodiment, the first parameter information configured by the network device for the terminal for ranging or lateral link positioning belongs to the parameter information in V2X service or ProSe service. That is to say, the network device does not need to send additional parameter information to the terminal, and the terminal can determine the first parameter information for ranging or lateral link positioning. There is no need for additional transmission of other parameters between the network device and the terminal, saving transmission resources.

[0073] exist Figure 2 Based on the illustrated embodiment, since the terminal can determine the first parameter information from the parameter information in the V2X service and the parameter information in the ProSe service, the second parameter information included in the V2X service and the third parameter information included in the ProSe service will be described below.

[0074] The second parameter information included in the V2X service includes at least one of the following:

[0075] (1) Authorization strategy.

[0076] Specifically, when the terminal is "served by E-UTRA (Evolved UMTS Terrestrial Radio Access Network)" or "served by NR (New Radio)," the licensing policy authorizes the terminal to perform V2X communication at at least one PLMN (Public Land Mobile Network) on a PC5 (one interface) reference point. For each PLMN, the authorized terminal performs V2X communication RAT on the PC5 reference point.

[0077] When the terminal is "not served by E-UTRA" or "not served by NR", this authorization policy determines whether the UE is authorized to perform V2X communication on the PC5 reference point. Furthermore, this authorization policy also authorizes the terminal to perform V2X communication via the RAT (Radio Access Network) on the PC5 reference point.

[0078] (2) Radio parameters when the terminal is not served by NG-RAN (The interface between the gNB and the 5G CN-RadioAccess Network).

[0079] The radio parameters include the radio parameters and geographic area of ​​each PC5 RAT (i.e., LTE PC5, NR PC5) and an indication of whether each PC5 RAT is "carrier-managed" or "non-carrier-managed".

[0080] When the terminal can be located in the corresponding geographical area, it performs V2X communication using radio parameters at the PC5 reference point when it is "not served by E-UTRA" or "not served by NR". However, if the terminal cannot be located in the corresponding geographical area, it is not authorized to transmit.

[0081] (3) Strategies / parameters for PC5 RAT selection and PC5 Tx profile selection.

[0082] (4) Strategies or parameters associated with privacy information.

[0083] The privacy information refers to information that provides security for the terminal and prevents information leakage.

[0087] (5) Select the strategy or parameters when choosing LTE PC5.

[0088] (6) Select the strategy or parameters when choosing NR PC5.

[0089] The strategy or parameter for selecting NR PC5 includes at least one of the following:

[0090] 1.1 Map V2X service types to V2X frequencies with geographical regions.

[0091] 1.2 Mapping of V2X service types to default communication modes (i.e., broadcast mode, multicast mode, or unicast mode).

[0092] 1.3 Mapping V2X service types to target Layer 2 IDs and broadcasting the mapping relationship.

[0093] 1.4 Mapping of V2X service types used for multicast mode communication to target Layer 2 IDs.

[0094] 1.5. Mapping of V2X service types to default target Layer 2 IDs, which is used for initial signaling to establish unicast connections.

[0095] (7) A validity timer that indicates the expiration time of a V2X strategy or parameter.

[0096] The validity timer indicates the expiration time of a V2X policy or parameter; that is, when the validity timer expires, the V2X policy or parameter becomes invalid.

[0097] The third parameter information included in the ProSe service includes two aspects: one is the third parameter information discovered directly, and the other is the third parameter information for direct communication.

[0098] The third-party parameter information directly discovered in ProSe services includes at least one of the following:

[0099] (1) Authorization strategy.

[0100] The authorization strategy will be explained in two scenarios below:

[0101] The first type: When the terminal is "NG-RAN serviced", the authorization policy is to open 5G ProSe direct discovery Model A monitoring authorization policy: the terminal is authorized to execute 5G ProSe direct discovery monitoring of PLMN.

[0102] Alternatively, when the terminal is "NG-RAN serviced", the authorization policy is the open 5G ProSe direct discovery Model A monitoring authorization policy: the UE is authorized to perform broadcast PLMN.

[0103] The second method: Direct discovery of restricted 5G ProSe, including:

[0104] Restricted 5G ProSe Direct Discovery Model A (Mode A) Monitoring Authorization Policy: Authorized terminals execute restricted 5G ProSe direct discovery of Model A monitoring PLMNs.

[0105] Alternatively, the restricted 5G ProSe direct discovery Model A announcement authorization policy: the terminal is authorized to execute the restricted 5G ProSe direct discovery Model A announced PLMN.

[0106] Alternatively, the restricted 5G ProSe direct discovery Model B (Mode B) discoverer operation authorization strategy: authorizes the PLMN to perform Model B discoverer operations.

[0107] Alternatively, the restricted 5G ProSe direct discovery Model B discovery operation authorization strategy: authorized terminals are authorized to perform Model B discoverer operations on the PLMN.

[0108] (2) Parameters used for direct discovery of 5G ProSe.

[0109] The ProSe service is mapped to the target Layer 2 ID, and this mapping is used for the initial signaling of sending / receiving discovery messages.

[0110] In some embodiments, the ProSe service is represented by the ProSe identifier.

[0111] (3) Radio parameters when the terminal is not served by NG-RAN.

[0112] These radio parameters include the radio parameters and geographic area for each NR PC5, as well as an indication of whether each NR PC5 is "carrier-managed" or "non-carrier-managed". When the terminal is able to locate itself in the corresponding geographic area, it performs 5G ProSe direct discovery at the PC5 reference point using the radio parameters when "not served by NG-RAN". Otherwise, the terminal is not authorized to transmit.

[0117] 1.2 Layer-2 Group ID: Layer-2 ID represents the application layer group ID;

[0118] 1.3 User Information ID: For model A, this corresponds to the user information parameters when the terminal is notifying the UE. For model B, this corresponds to the discoverer information in the request message and the discoverer information in the response message, respectively, when the terminal acts as either the discoverer or the discoverer terminal.

[0119] (6) A validity timer that indicates the expiration time of the 5G ProSe direct discovery strategy / parameter.

[0120] The validity timer indicates the expiration time of the 5G ProSe direct discovery policy / parameter. In other words, the 5G ProSe direct discovery policy / parameter expires when the validity timer expires.

[0121] The third parameter information for direct communication in ProSe services includes at least one of the following:

[0122] (1) Authorization strategy:

[0123] When the terminal is "served by NG-RAN", the authorized terminal performs 5G ProSe direct communication with the PLMN at the PC5 reference point.

[0124] When the terminal is "not served by NG-RAN", is the terminal authorized to perform 5GProSe direct communication through the PC5 reference point?

[0128] 1.2 Application Layer Group ID: Identifies the application layer group to which the terminal belongs.

[0146] exist Figure 2 Based on the illustrated embodiment, the first parameter information includes at least one of the following:

[0147] (1) Dedicated parameter information used for ranging or lateral link positioning.

[0148] The specific parameter information refers to parameter information used only for ranging or lateral link positioning.

[0149] In some embodiments, the dedicated parameter information used for ranging or lateral link positioning is a parameter obtained by extending it through V2X services or ProSe services.

[0150] (2) General parameter information used for ranging or side-link positioning and V2X services.

[0151] (3) General parameter information used for ranging or side-link positioning and ProSe services.

[0152] Among them, the general parameter information refers to information that is applicable not only to ranging or side-link positioning, but also to V2X services or ProSe services.

[0153] In some embodiments, direct discovery refers to a terminal searching for other terminals through a side link. For direct discovery, the dedicated parameter information includes parameters used for direct discovery.

[0154] For direct communication, which refers to communication between terminals via a side link, the dedicated parameter information includes at least one of the following:

[0155] (1) Strategies / parameters for PC5 RAT selection and PC5 Tx profile selection.

[0156] (2) Strategies or parameters associated with privacy information.

[0157] (3) Select the strategy or parameters when choosing LTE PC5.

[0158] (4) Select the strategy or parameters when choosing NR PC5.

[0159] (5) Authorization strategy for ranging or lateral link positioning.

[0160] Optionally, when the terminal is served by NG-RAN or EUTRAN, the authorization policy used for ranging or lateral link positioning includes at least one of the following:

[0161] (1) For terminals with ranging / sidelink positioning capabilities, one or more PLMNs authorized to perform ranging / sidelink positioning as reference terminals or target terminals.

[0162] (2) For terminals with ranging / side traverse positioning capabilities, they are authorized to perform ranging / side traverse positioning to obtain one or more PLMNs with relevant distances.

[0163] (3) For terminals with ranging / side traverse positioning capabilities, they are authorized to perform ranging / side traverse positioning to obtain one or more PLMNs in the relevant direction.

[0164] (4) For terminals with ranging / sidelink positioning capabilities, they are authorized to perform high-precision ranging / sidelink positioning to obtain one or more PLMNs with relevant distances.

[0165] (5) For terminals with ranging / side traversing link positioning capabilities, they are authorized to perform high-precision ranging / side traversing link positioning to obtain one or more PLMNs in the relevant direction.

[0166] It should be noted that, in this embodiment, the difference between PLMN performing ranging / lateral traversal positioning and performing high-precision ranging / lateral traversal positioning lies in the accuracy of the distance and direction obtained. The accuracy of PLMN performing high-precision ranging / lateral traversal positioning is higher than that of performing ranging / lateral traversal positioning.

[0167] For example, the distance accuracy obtained by a PLMN performing high-precision ranging / lateral traversal positioning is 5 meters, while the accuracy obtained by a PLMN performing ranging / lateral traversal positioning is 15 meters. This means the accuracy of the distance obtained by the PLMN performing high-precision ranging / lateral traversal positioning is higher than the accuracy obtained by the PLMN performing ranging / lateral traversal positioning. Alternatively, the direction accuracy obtained by a PLMN performing high-precision ranging / lateral traversal positioning is 2 degrees, while the accuracy obtained by the PLMN performing ranging / lateral traversal positioning is 3 degrees. This means the accuracy of the direction obtained by the PLMN performing high-precision ranging / lateral traversal positioning is higher than the accuracy obtained by the PLMN performing ranging / lateral traversal positioning.

[0168] Optionally, when the terminal is not served by NG-RAN and not by EUTRAN, the authorization policy used for ranging or sidelink positioning includes at least one of the following:

[0169] (1) For terminals with ranging / lateral traverse positioning capabilities, is the terminal authorized to perform ranging / lateral traverse positioning as a reference terminal or target terminal?

[0170] In some embodiments, the authorization policy includes 1 bit to indicate whether the terminal is authorized to perform ranging / lateral link positioning as a reference terminal or a target terminal.

[0171] For example, if one bit in the authorization policy is 0, it means that the terminal is not authorized to perform ranging / lateral traversal positioning as a reference terminal or target terminal. If one bit in the authorization policy is 1, it means that the terminal is authorized to perform ranging / lateral traversal positioning as a reference terminal or target terminal.

[0172] (2) For terminals with ranging / lateral traverse positioning capabilities, is the terminal authorized to perform ranging / lateral traverse positioning to obtain relevant distances?

[0173] (3) For terminals with ranging / lateral traverse positioning capabilities, is the terminal authorized to perform ranging / lateral traverse positioning to obtain relevant directions?

[0174] (4) For terminals with ranging / side traverse positioning capabilities, is the terminal authorized to perform high-precision ranging / side traverse positioning to obtain relevant distances?

[0175] (5) For terminals with ranging / lateral traverse positioning capabilities, is the terminal authorized to perform high-precision ranging / lateral traverse positioning to obtain relevant directions?

[0176] It should be noted that, in this embodiment, the difference between PLMN performing ranging / lateral traversal positioning and performing high-precision ranging / lateral traversal positioning lies in the accuracy of the distance and direction obtained. The accuracy of PLMN performing high-precision ranging / lateral traversal positioning is higher than that of performing ranging / lateral traversal positioning.

[0177] For example, the distance accuracy obtained by a PLMN performing high-precision ranging / lateral traversal positioning is 5 meters, while the accuracy obtained by a PLMN performing ranging / lateral traversal positioning is 15 meters. This means the accuracy of the distance obtained by the PLMN performing high-precision ranging / lateral traversal positioning is higher than the accuracy obtained by the PLMN performing ranging / lateral traversal positioning. Alternatively, the direction accuracy obtained by a PLMN performing high-precision ranging / lateral traversal positioning is 2 degrees, while the accuracy obtained by the PLMN performing ranging / lateral traversal positioning is 3 degrees. This means the accuracy of the direction obtained by the PLMN performing high-precision ranging / lateral traversal positioning is higher than the accuracy obtained by the PLMN performing ranging / lateral traversal positioning.

[0203] For example, when the terminal supports ranging or lateral link positioning for V2X services, the terminal not only sends a V2X policy request during the registration process, but also sends a registration request to obtain the first parameter information.

[0236] In some embodiments, the authorization policy includes 1 bit to indicate whether the terminal is authorized to perform ranging / lateral link positioning as a reference terminal or a target terminal.

[0237] For example, if one bit in the authorization policy is 0, it means that the terminal is not authorized to perform ranging / lateral traversal positioning as a reference terminal or target terminal.

[0279] Optionally, when the terminal is served by NG-RAN or EUTRAN, the authorization policy used for ranging or lateral link positioning includes at least one of the following:

[0280] (1) For terminals with ranging / sidelink positioning capabilities, one or more PLMNs authorized to perform ranging / sidelink positioning as reference terminals or target terminals.

[0286] (1) For terminals with ranging / lateral traverse positioning capabilities, is the terminal authorized to perform ranging / lateral traverse positioning as a reference terminal or target terminal?

[0287] In some embodiments, the authorization policy includes 1 bit to indicate whether the terminal is authorized to perform ranging / lateral link positioning as a reference terminal or a target terminal.

[0288] For example, if one bit in the authorization policy is 0, it means that the terminal is not authorized to perform ranging / lateral traversal positioning as a reference terminal or target terminal. If one bit in the authorization policy is 1, it means that the terminal is authorized to perform ranging / lateral traversal positioning as a reference terminal or target terminal.

[0292] (5) For terminals with ranging / lateral traverse positioning capabilities, is the terminal authorized to perform high-precision ranging / lateral traverse positioning to obtain relevant directions?

[0293] Optionally, the terminal can send a policy configuration request to the PCF at any time to obtain the first parameter information.

[0294] For example, if the validity timer for the second parameter information of the V2X service expires, the terminal sends a policy configuration request to the PCF. Alternatively, if the terminal does not have the first parameter information, the terminal sends a policy configuration request to the PCF.

[0295] For example, if the validity timer for the third parameter information of the ProSe service expires, the terminal sends a policy configuration request to the PCF. Alternatively, if the terminal does not have the first parameter information, the terminal sends a policy configuration request to the PCF.

[0296] It should be noted that the embodiments in this application are only illustrated by using the PCF to configure the first parameter information for the terminal as an example. In another embodiment, when the PCF determines the different functions supported by the terminal indicated by the request information, it determines the parameter information to be sent to the terminal. The following describes how the PCF sends the parameter information to the terminal.

[0297] The first scenario: When the request message is used to request first parameter information for ranging or lateral link positioning of the terminal, and to request second parameter information for V2X services, the PCF is used to respond to the request message by sending the second parameter information for V2X services and the first parameter information for the terminal to perform ranging or lateral link positioning.

[0298] In this embodiment, the request message sent by the terminal to the PCF is used to request the second parameter information of the V2X service and the first parameter information for the terminal to perform ranging or lateral link positioning. Therefore, the PCF can carry the first and second parameter information in the V2X service return message. Alternatively, it can be understood that if the PCF determines that the request information is for requesting the first parameter information for the terminal's ranging or lateral link positioning, and also requests the second parameter information of the V2X service, then the PCF can include the first parameter information in the returned V2X service parameter information, so that both the second and first parameter information can be returned to the terminal simultaneously.

[0299] The second scenario: When the request message is used to request the first parameter information for ranging or lateral link positioning of the terminal, and the third parameter information for ProSe service, PCF is used to respond to the request message by sending the third parameter information for ProSe service and the first parameter information for the terminal to perform ranging or lateral link positioning.

[0300] In this embodiment, the request message sent by the terminal to the PCF is used to request the third parameter information of the ProSe service and the first parameter information for the terminal to perform ranging or lateral link positioning. Therefore, the PCF can carry the first and third parameter information in the return message of the ProSe service. Alternatively, it can be understood that if the PCF determines that the request information is for requesting the first parameter information for the terminal's ranging or lateral link positioning, and also requests the third parameter information of the ProSe service, then the PCF can include the first parameter information in the returned ProSe service parameter information, so that both the third and first parameter information can be returned to the terminal simultaneously.

[0301] The third type: When the request information is used to request the first parameter information for ranging or lateral link positioning of the terminal, the second parameter information for V2X service, and the third parameter information for ProSe service, the PCF is used to respond to the request message by sending the second parameter information for V2X service, the third parameter information for ProSe service, and the first parameter information for the terminal to perform ranging or lateral link positioning.

[0302] In this embodiment, the request message sent by the terminal to the PCF is used to request the second parameter information of the V2X service, the third parameter information of the ProSe service, and the first parameter information for the terminal to perform ranging or lateral link positioning. The PCF can then carry the first and second parameter information in the V2X service return message, and the first and third parameter information in the ProSe service return message. Alternatively, it can be understood that when the PCF determines that the request information is for requesting the first parameter information for the terminal's ranging or lateral link positioning, the second parameter information for the V2X service, and the third parameter information for the ProSe service, it can include the first parameter information in the returned V2X service parameter information and in the returned ProSe service parameter information, so that the third and first parameter information, as well as the second and first parameter information, can be returned to the terminal simultaneously.

[0303] It should be noted that the embodiments in this application are only illustrated using request information as an example. In another embodiment, the request information may also be information received from the terminal policy container. That is, the terminal sends the terminal policy container, carrying a request for obtaining parameter information, to the PCF. The PCF can then determine the parameter information requested by the terminal based on the information received from the terminal policy container, and then return the determined parameter information to the terminal.

[0304] See Figure 4 The process by which PCF configures the first parameter information for the terminal includes:

[0305] 1. The terminal sends a policy configuration request to the AMF through the access network equipment.

[0306] 2. The AMF forwards the received policy configuration request information to the PCF.

[0307] 3. Based on the received policy configuration request information, PCF returns the first parameter information to the terminal.

[0308] The method provided in this application embodiment allows the terminal to obtain first parameter information from the PCF through a request message, and the PCF does not need to send additional parameter information to the terminal. The terminal can determine the first parameter information used for ranging or lateral link positioning. There is no need for additional transmission of other parameters between the network device and the terminal, saving transmission resources.

[0309] exist Figure 2 Based on the illustrated embodiment, the terminal will also perform ranging or lateral link positioning based on the acquired first parameter information. See also Figure 5 The method includes:

[0310] Step 501: The terminal performs ranging or lateral link positioning based on the first parameter information.

[0311] In this embodiment of the application, after the terminal receives the first parameter information sent by the network device, since the first parameter information is used by the terminal to perform ranging or lateral link positioning, ranging or lateral link positioning can be performed based on the first parameter information.

[0312] In the solution provided in this application embodiment, the network device does not need to send additional parameter information to the terminal, and the terminal can determine the first parameter information used for ranging or lateral link positioning. There is no need for additional transmission of other parameters between the network device and the terminal, saving transmission resources.

[0313] Figure 6 The flowchart illustrates a parameter configuration method provided in an exemplary embodiment of this application, which can be applied to, for example, Figure 1 In the terminal shown, the method includes at least some of the following:

[0314] Step 601: The terminal sends a request message to the PCF, which instructs the PCF to send first parameter information. The first parameter information is used by the terminal to perform ranging or side-link positioning. The first parameter information belongs to at least one of multiple second parameter information in the V2X service, and / or the first parameter information belongs to at least one of multiple third parameter information in the ProSe service.

[0315] In some embodiments, when the request message is used to request first parameter information for ranging or lateral link positioning of the terminal, and to request second parameter information for V2X services, the PCF is used to send the second parameter information for V2X services and the first parameter information for the terminal to perform ranging or lateral link positioning in response to the request message.

[0316] In this embodiment of the application, the request message sent by the terminal to the PCF is used to request the second parameter information of the V2X service and the first parameter information for the terminal to perform ranging or side-link positioning. Then the PCF can carry the first parameter information and the second parameter information in the return message of the V2X service.

[0317] In some embodiments, when the request message is used to request first parameter information for ranging or lateral link positioning of the terminal, and to request third parameter information for the ProSe service, the PCF is used to send the third parameter information for the ProSe service and the first parameter information for the terminal to perform ranging or lateral link positioning in response to the request message.

[0318] In this embodiment of the application, the request message sent by the terminal to the PCF is used to request the third parameter information of the ProSe service and the first parameter information for the terminal to perform ranging or lateral link positioning. Then the PCF can carry the first parameter information and the third parameter information in the return message of the ProSe service.

[0319] In some embodiments, when the request message is used to request first parameter information for ranging or lateral link positioning of the terminal, second parameter information for V2X service, and third parameter information for ProSe service, the PCF is used to send the second parameter information for V2X service, the third parameter information for ProSe service, and the first parameter information for the terminal to perform ranging or lateral link positioning in response to the request message.

[0320] In this embodiment of the application, the request message sent by the terminal to the PCF is used to request the acquisition of the second parameter information of the V2X service, the third parameter information of the ProSe service, and the first parameter information for the terminal to perform ranging or lateral link positioning. Then the PCF can carry the first parameter information and the second parameter information in the return message of the V2X service, and carry the first parameter information and the third parameter information in the return message of the ProSe service.

[0321] It should be noted that the embodiments in this application are only illustrated using request information as an example. In another embodiment, the request information may also be information received from the terminal policy container. That is, the terminal sends the terminal policy container, carrying a request for obtaining parameter information, to the PCF. The PCF can then determine the parameter information requested by the terminal based on the information received from the terminal policy container, and then return the determined parameter information to the terminal.

[0322] In the solution provided in this application embodiment, the first parameter information configured by the network device for the terminal for ranging or lateral link positioning belongs to the parameter information in V2X service or ProSe service. That is to say, the network device does not need to send additional parameter information to the terminal, and the terminal can determine the first parameter information for ranging or lateral link positioning. There is no need for additional transmission of other parameters between the network device and the terminal, saving transmission resources.

[0323] Figure 7 The flowchart illustrates a parameter configuration method provided in an exemplary embodiment of this application, which can be applied to, for example, Figure 1 In the PCF shown, the method includes at least some of the following:

[0324] Step 701: The PCF receives a request message sent by the terminal. The request message is used to instruct the PCF to send first parameter information. The first parameter information is used by the terminal to perform ranging or lateral link positioning. The first parameter information belongs to at least one of multiple second parameter information in the V2X service, and / or the first parameter information belongs to at least one of multiple third parameter information in the ProSe service.

[0325] In some embodiments, when it is determined that the request information is used to request first parameter information for ranging or lateral link positioning of the terminal, and to request second parameter information for V2X services, the second parameter information for V2X services and the first parameter information for the terminal to perform ranging or lateral link positioning are sent in response to the request message.

[0326] If the PCF determines that the requested information is for requesting first parameter information for ranging or lateral link positioning of the terminal, and for requesting second parameter information for V2X services, then the PCF can include the first parameter information in the returned V2X service parameter information, so that the second parameter information and the first parameter information can be returned to the terminal simultaneously.

[0327] In some embodiments, when it is determined that the request information is used to request first parameter information for ranging or lateral link positioning of the terminal, and to request third parameter information for the ProSe service, the third parameter information for the ProSe service and the first parameter information for the terminal to perform ranging or lateral link positioning are sent in response to the request message.

[0328] If the PCF determines that the requested information is for requesting first parameter information for ranging or lateral link positioning of the terminal, and for requesting third parameter information for the ProSe service, then the PCF can include the first parameter information in the returned ProSe service parameter information, so that the third parameter information and the first parameter information can be returned to the terminal simultaneously.

In another embodiment, the request information may also be information received from the terminal policy container. That is, the terminal sends the terminal policy container, carrying a request for obtaining parameter information, to the PCF. The PCF can then determine the parameter information requested by the terminal based on the information received from the terminal policy container, and then return the determined parameter information to the terminal.

[0332] In the solution provided in this application embodiment, the first parameter information configured by the network device for the terminal for ranging or lateral link positioning belongs to the parameter information in V2X service or ProSe service. That is to say, the network device does not need to send additional parameter information to the terminal, and the terminal can determine the first parameter information for ranging or lateral link positioning.
