Description

[0001] Cross-reference to related applications

[0002] This application is based on and claims priority to international application No. PCT / CN2021 / 087488, filed on April 15, 2021, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to mobile communication technology, and more particularly to a wireless communication method, device, and storage medium. Background Technology

[0004] In related technologies, when a remote user equipment (Remote UE) with proximity-based services (ProSe) capability establishes a direct connection with a relay user equipment (Relay UE) through the PC5 interface and interacts with the external network through a Protocol Data Unit (PDU) session established by the Relay UE with the 5th generation (5G) network, the Policy Control Function (PCF) controls the quality of service (QoS) from the Relay UE to the external network. For example, if the transmission latency is 100ms, the Relay UE can determine the QoS on the PC5 interface based on its own configuration, such as a transmission latency of 50ms. However, the remote UE only obtains the QoS of the PC5 interface from the Relay UE (e.g., the transmission latency is 50ms) and does not know the end-to-end QoS of its own transmitted services.

[0053] To gain a more detailed understanding of the features and technical content of the embodiments of the present invention, the implementation of the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of the present invention.

[0054] Before providing a detailed description of the random access method provided in the embodiments of the present invention, a brief explanation of some of the ProSe technologies will be given first.

[0055] ProSe enables direct discovery of physically nearby users and facilitates direct communication between these users.

[0056] Figure 1 This is a schematic diagram of the network architecture of a 5G system, such as... Figure 1 As shown, it includes: Access and Mobility Management Function (AMF), Session Management Function (SMF), Policy Control Function, Authentication Server Function (AUSF), Unified Data Management (UDM), User Plane Function (UPF), Network Slice Selection Function (NSSF), and Application Function (AF).

[0057] Furthermore, this network architecture also includes access network (R)AN equipment, user equipment (UE), and data network (DN) elements. UEs can connect to the AMF, and the R)AN can also connect to the AMF. The R)AN can also connect to the UPF. The UPF can connect to the SMF and DN respectively. The AMF can connect to the SMF, UDM, PCF, NSSF, and AUSF respectively. The SMF connects to the PCF and UDM respectively. The PCF connects to the AF. Both the AMF and SMF can obtain data from the UDM, such as user subscription data, and both the AMF and SMF can obtain policy data from the PCF. For example, the PCF element obtains user subscription data from the UDM and sends it to the AMF and SMF, which then distribute it to the R)AN, UE, and UPF, etc.

[0058] The AMF (Active Mobility Management Entity) is primarily used for terminal device registration, mobility management, and tracking area update processes in mobile networks. The mobility management network element terminates non-access stratum (NAS) messages, completes registration management, connection management, reachability management, allocates tracking area lists (TA lists), and performs mobility management, and transparently routes session management (SM) messages to the session management network element. In 4G communication, the AMF can be replaced by the Mobility Management Entity (MME). In future communication such as 6G communication, the AMF can still be the AMF, or a network element with other names that support mobility management functions; this invention does not limit this.

[0059] SMF (Session Management Function) is primarily used for session management in mobile networks, such as session creation, modification, and release. Specific functions include assigning Internet Protocol (IP) addresses to users and selecting user plane network elements that provide packet forwarding capabilities. In 4G, SMF can be replaced by Packet Data Network Gateway (PGW). In future communications such as 6G, SMF can still be SMF, or other network elements with names that support session management functions; this invention does not limit the specific application of SMF.

[0060] The PCF (Policy and Charging Rules Function) includes user subscription data management, policy control, charging policy control, and QoS control. In 4G, the PCF can be replaced by the policy and charging rules function (PCRF). In future communications such as 6G, the PCF can still be the PCF, or other network elements that support policy control functions; this invention does not limit this.

[0061] The AUSF (Authorized Unified Authentication Server) is primarily used to authenticate service functions and store keys using an Extensible Authentication Protocol (EAP) to achieve user authentication and authorization. In 4G, the AUSF can be replaced by an authentication, authorization, and accounting server (AAA). In future communications such as 6G, the AUSF can still be an AUSF or a network element with other names that support authentication functions; this invention does not limit this.

[0062] UDM is primarily used to store user data, such as subscription information and authentication / authorization information. In 4G, UDM can be replaced by Home Subscriber Server (HSS). In future communications such as 6G, UDM can still be UDM, or other network elements with names that support data management functions; this invention does not limit this.

[0063] UPF (User Plane Function) is primarily used for user plane service processing, such as service routing, packet forwarding, anchoring, QoS mapping and enforcement, uplink identification and routing to the data network, downlink packet buffering and downlink data arrival notification triggering, and connection to external data networks. In 4G, UPF can be replaced by the user plane function of the Packet Data Network Gateway (PGW). In future communications such as 6G, UPF can still be UPF, or other network elements with names that support user plane functions; this invention does not limit this.

[0064] (R)AN is a device that provides wireless communication functions for terminal devices, including but not limited to: next-generation base stations (gnodeB, gNB) in 5G, evolved node B (eNB), radio network controller (RNC), node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved nodeB, or home node B, HNB), base band unit (BBU), transmitting and receiving point (TRP), transmitting point (TP), mobile switching center, etc.

[0065] A UE (User Equipment) is a wireless transceiver device that can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on water (such as on ships); and it can be deployed in the air (such as on airplanes, balloons, and satellites). Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminals, augmented reality (AR) terminals, wireless terminals in industrial control, self-driving, remote medical care, smart grids, transportation safety, smart cities, and smart homes, among others.

[0066] DN is mainly used to provide services to users, such as operator services, Internet access services, and third-party services.

[0067] The core network (CN), acting as the bearer network, provides interfaces to the DN, offering communication connectivity, authentication, management, communication, and data service delivery to terminal devices. Figure 1 In the network architecture shown, core network functions are divided into user plane functions and control plane functions. User plane functions are mainly responsible for packet forwarding and QoS control. Control plane functions are mainly responsible for user registration and authentication, mobility management, and issuing packet forwarding policies or QoS control policies to the UPF (User-Defined Front-End). The control plane functions mainly include core access and mobility management (AMF) network elements and session management (SMF) network elements. Specifically, AMF network elements are responsible for the user registration process during access, location management during user movement, and paging of terminal devices. SMF network elements are responsible for establishing corresponding session connections on the core network side when a user initiates a service, providing specific services to the user. In 5G, CN can be the 5G core network (5GC).

[0068] like Figure 1As shown, the interfaces and connections in the network architecture can include: Uu, N1, N2, N3, N4, N5, N6, N7, N8, N10, N11, N12, N13, N14, N15, and N22. Among them, Uu is the connection between the terminal device and the RAN; N1 is the control plane connection between the terminal device and the AMF network element, used to transmit control signaling between the user equipment and the core network control plane; specific messages in the N1 connection can be transmitted through the connection between the terminal device and the RAN, or the N2 connection between the RAN and the AMF network element; N2 is the control plane connection between the RAN and the AMF network element; N3 is the connection between the RAN and the user plane function; and N4 is the connection between the SMF network element and the user plane function, used to transmit control signaling between the SMF network element and the user plane function. N5 is the connection between PCF and AF; N6 is the connection between User Plane Function and DN; N7 is the connection between SMF and PCF; N8 is the connection between AMF and UDM; N10 is the connection between UDM and SMF; N11 is the connection between AMF and SMF; N12 is the connection between AUSF and AMF; N13 is the connection between AUSF and UDM; N14 is the interface between AMFs; N15 is the connection between AMF and PCF; and N22 is the connection between NSSF and AMF.

[0069] After the UE accesses the 5G network through the Uu interface, it establishes a QoS stream for data transmission under the control of the SMF. The transmission quality parameters of the QoS stream include the 5G QoS Identifier (5QI). The 5QI can be mapped to a series of QoS characteristics such as latency, bit error rate, and scheduling priority.

[0070] In one example, 5QI is shown in Table 1. The value of 5QI is 66, which represents the following QoS characteristics: priority 20, latency 100ms, and bit error rate 10. -2 .

[0071] Table 1 5QI Examples

[0072] 5QI Value Priority Delay Bit error rate 66 20 100ms <![CDATA[10 -2 ]]>

[0073] like Figure 2A UE with ProSe capability can also communicate directly with another UE with ProSe capability via the PC5 interface, which is the UE's current interface. A PC5 QoS data stream is established between the two UEs to ensure the transmission of service data while meeting the corresponding QoS requirements, thereby guaranteeing the quality of service in PC5 communication. The QoS parameters of the PC5 QoS data stream include the PC5 5G QoS identifier (PC5 5QI, PQI), which can be mapped to a series of QoS characteristics such as latency, bit error rate, and scheduling priority.

[0074] In one example, as shown in Table 2, a 5QI value of 95 represents the following QoS characteristics: priority 2, latency 200ms, and bit error rate 10. -2 .

[0075] Table 2 PQI Examples

[0076] PQI Priority Delay Bit error rate 95 2 200ms <![CDATA[10 -2 ]]> 58 4 100ms <![CDATA[10 -2 ]]> 57 5 25ms <![CDATA[10 -1 ]]>

[0077] like Figure 2 As shown, UE1 and UE2 include three PC5 unicast links. There are two PC5 unicast links between application A on UE1 and application A on UE2, with one PC5 unicast link providing PC5 QoS data stream #1 and the other providing PC5 QoS data stream #2. There is one PC5 unicast link between application B on UE1 and application B on UE2, with the data stream being PC5 QoS data stream #3. One of UE1 and UE2 is a Remote UE, and the other is a Relay UE.

[0078] like Figure 3 As shown, when a UE has both the ability to connect to an external data network via a 5G network and ProSe capability, this UE can act as a relay UE. Another remote UE with ProSe capability can establish a direct connection with the Relay UE through the PC5 interface, and establish a PDU session with the 5G network (including NG-RAN and 5GC) through the Relay UE. The established PDU session is used to interact with the application server (AS) of the external network.

[0079] In related technologies, when a Remote UE with Prose capability establishes a direct connection with a Relay UE through the PC5 interface and interacts with the external network through a PDU session established between the Relay UE and the 5G network, the PCF controls the service quality of the Relay UE to the external network. For example, if the transmission latency is 100ms, the Relay UE can determine the service quality on the PC5 interface according to its own configuration. For example, if the transmission latency is 50ms, the Remote UE only obtains the service quality of the PC5 interface from the Relay UE (e.g., the transmission latency is 50ms) and does not know the end-to-end service quality of its own transmitted services (i.e., the service quality of Uu+PC5 is 150ms). Therefore, it cannot know whether its service data is transmitted according to the application layer requirements.

[0080] To address the aforementioned problems, this invention provides a wireless communication method. This method can be applied to various communication systems, such as: Global System for Mobile communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), or 5G systems, etc.

The communication system 400 may include network device 410, which may be a device that communicates with terminal device 420 (or a communication terminal, terminal).

[0082] The communication system 400 also includes at least one terminal device 420 located within the coverage area of ​​the network device 410.

[0083] Optionally, the terminal devices 420 can perform device-to-device (D2D) communication with each other.

[0084] In this embodiment of the invention, any terminal device 420 may be a relay terminal device 420-1, and any other terminal device 420 other than the relay terminal device 420-1 may be a remote terminal device 420-2, and the remote terminal device 420-2 interacts with the network device 410 through the relay terminal device 420-1.

[0085] Alternatively, a 5G system or 5G network may also be referred to as an NR system or NR network.

[0086] Figure 4 An exemplary diagram shows a network device and three terminal devices. Optionally, the communication system 400 may include multiple network devices and each network device may include other numbers of terminal devices within its coverage area.

[0089] Figure 5 An optional processing flow of the wireless communication method provided in this embodiment of the invention is applied to a first terminal, such as... Figure 5 As shown, it includes the following steps:

[0090] S501, The first terminal device receives the authorized first QoS parameters sent by the first network device;

[0091] The authorized first QoS parameter represents the quality of service requirements between the first terminal device and the core network user plane anchor point.

[0092] The first network device configures authorized first QoS parameters for the first terminal device and sends the configured authorized first QoS parameters to the first terminal device.

[0093] Optionally, the first terminal device is a Relay UE, and the authorized first QoS parameter represents the quality of service requirements between the Relay UE and the core network user plane anchor point, that is, the quality of service requirements of the data transmitted through the Uu interface.

[0094] In this embodiment of the invention, the authorized first QoS parameter may characterize one or more of the following QoS features: priority, latency, and bit error rate.

[0095] Optionally, the first QoS parameter granted includes 5QI.

[0096] S502, the first terminal device determines the authorized second QoS parameters based on the authorized first QoS parameters;

[0097] The authorized second QoS parameter represents the quality of service requirements between the second terminal device and the core network user plane anchor point; the second terminal device transmits data with the core network user plane anchor point through the first terminal device.

[0098] Optionally, the second terminal device is a Remote UE, and the authorized second QoS parameter represents the quality of service requirements between the Remote UE and the core network user plane anchor point.

[0099] The authorized second QoS parameter can characterize one or more of the following QoS features: priority, delay, and bit error rate.

[0100] Optionally, the authorized second QoS parameter may include 5QI or PQI.

[0101] The authorized second QoS parameter can be determined in one of the following ways:

[0102] Method A1: Determined based on at least one first correspondence and the authorized first QoS parameter;

[0103] Method A2: Determined based on the first authorized QoS parameter and the third authorized QoS parameter;

[0104] Method A3: Determined based on the first authorized QoS parameter and the second requested QoS parameter.

[0105] S503, the first terminal device sends the authorized second QoS parameters to the second terminal device.

[0106] After determining the authorized second QoS parameters, the first terminal sends the authorized second QoS parameters to the second terminal device, enabling the second terminal device to know the quality of service requirements for its interaction with the network side, thereby controlling its own data transmission.

[0107] The wireless communication method provided in this embodiment of the invention includes a first terminal device receiving an authorized first QoS parameter sent by a first network device. The authorized first QoS parameter represents the quality of service requirements between the first terminal device and a core network user plane anchor point. The first terminal device determines an authorized second QoS parameter based on the authorized first QoS parameter. The authorized second QoS parameter represents the quality of service requirements between a second terminal device and the core network user plane anchor point. The second terminal device transmits data with the core network user plane anchor point through the first terminal device. The first terminal device sends the authorized second QoS parameter to the second terminal device. This allows the first terminal device to determine the authorized second QoS parameter based on the authorized first QoS parameter sent by the first network device, and the second terminal device, transmitting data with the core network user plane anchor point through the first terminal device, can receive the authorized second QoS parameter from the first terminal device. This enables the second terminal device to understand its own quality of service requirements when interacting with the core network user plane anchor point, thereby effectively controlling its own nearby services and ensuring the effective transmission of its nearby service data.

[0119] This invention provides a wireless communication method, such as... Figure 8 As shown, it includes:

[0120] S801, The first network device sends the authorized first QoS parameters to the first terminal device;

[0121] S802, the first terminal device determines the authorized second QoS parameters based on the authorized first QoS parameters;

[0122] S803, the first terminal device sends the authorized second QoS parameters to the second terminal device.

[0123] For descriptions of S801, S802, and S803, please refer to [link to relevant documentation]. Figure 5 The descriptions of S501, S502, and S503 will not be repeated here.

[0124] In the above method A1, the first terminal device determines the authorized second QoS parameters based on at least one first correspondence and the authorized first QoS parameters.

[0125] The authorized second QoS parameter is determined based on the authorized first QoS parameter and at least one first correspondence; the first correspondence is at least the correspondence between the first QoS parameter and the second QoS parameter.

[0126] In some embodiments, the first correspondence is a correspondence between a first QoS parameter and a second QoS parameter. In this case, the first terminal device determines the second QoS parameter included in the first correspondence that includes the authorized first QoS parameter as the authorized second QoS parameter.

[0127] In one example, the first terminal device determines the authorized second QoS parameter based on the following three first correspondences: the correspondence between QoS parameter 1A and QoS parameter 2A, the correspondence between QoS parameter 1B and QoS parameter 2B, and the correspondence between QoS parameter 1C and QoS parameter 2C. Here, QoS parameter 1A, QoS parameter 1B, and QoS parameter 1C are different first QoS parameters, and QoS parameter 2A, QoS parameter 2B, and QoS parameter 2C are different second QoS parameters. When the authorized first QoS parameter is QoS parameter 1B, the correspondence between QoS parameter 1B and QoS parameter 2B includes the authorized first QoS parameter, and the authorized second QoS parameter is determined to be QoS parameter 2B based on this correspondence.

[0128] In some embodiments, such as Figure 9 As shown, before S801, the following steps are also performed:

[0129] S901, the first terminal device receives at least one first correspondence configured by the second network device.

[0130] At this time, the first terminal device determines the authorized second QoS parameters based on at least one first correspondence and the authorized first QoS parameters.

[0131] In some embodiments, the at least one first correspondence is configured by the second network device to the first terminal device.

[0132] The second network device configures at least one first correspondence and sends at least one first correspondence to the first terminal device.

[0133] Optionally, the second network device includes a PCF.

[0134] In some embodiments, the first correspondence is a correspondence between a first QoS parameter, a second QoS parameter, and a third QoS parameter; the at least one first correspondence is further used to determine an authorized third QoS parameter with the authorized first QoS parameter; the authorized third QoS parameter represents the quality of service requirements between the first terminal device and the second terminal device.

[0135] The first terminal device determines the authorized third QoS parameter based on the authorized first QoS parameter and the at least one first correspondence.

[0136] The first correspondence includes: a first QoS parameter, a second QoS parameter, and a third QoS parameter. The first terminal device determines the third QoS parameter included in the first correspondence, which includes the authorized first QoS parameter, as the authorized third QoS parameter.

[0137] In one example, the first terminal device determines the authorized third QoS parameter based on the following three first correspondences: the correspondence between QoS parameter 1A, QoS parameter 2A, and QoS parameter 3A; the correspondence between QoS parameter 1B, QoS parameter 2B, and QoS parameter 3B; and the correspondence between QoS parameter 1C, QoS parameter 2C, and QoS parameter 3C. Here, QoS parameter 1A, QoS parameter 1B, and QoS parameter 1C are different first QoS parameters; QoS parameter 2A, QoS parameter 2B, and QoS parameter 2C are different second QoS parameters; and QoS parameter 3A, QoS parameter 3B, and QoS parameter 3C are different third QoS parameters. When the authorized first QoS parameter is QoS parameter 1B, the correspondence between QoS parameter 1B, QoS parameter 2B, and QoS parameter 3B includes the authorized first QoS parameter. Based on this correspondence, the authorized third QoS parameter is determined to be QoS parameter 3B.

[0138] Optionally, the authorized third QoS parameter represents the quality of service requirements for the Remote UE and the Relay UE, i.e., the quality of service requirements for the data transmitted by PC5.

[0139] In this embodiment of the invention, the authorized third QoS parameter may characterize one or more of the following QoS features: priority, delay, and bit error rate.

[0140] Optionally, the authorized third QoS parameter includes PQI.

[0141] In method A2 above, the authorized second QoS parameter is determined based on the authorized first QoS parameter and the authorized third QoS parameter; the authorized third QoS parameter represents the quality of service requirements between the first terminal device and the second terminal device.

[0142] The first terminal determines an authorized third QoS parameter; the authorized third QoS parameter represents the quality of service requirements between the first terminal device and the second terminal device; the first terminal determines an authorized second QoS parameter based on the authorized first QoS parameter and the authorized third QoS parameter.

[0143] Taking the authorized first QoS parameter, authorized second QoS parameter, and authorized third QoS parameter to represent latency as an example, if the authorized first QoS parameter represents a latency of 100ms and the authorized third QoS parameter represents a latency of 50ms, then the latency represented by the determined authorized second QoS parameter is less than or equal to 150ms. Here, if a second QoS parameter representing 150ms exists, then that second QoS parameter is determined as the authorized second QoS parameter. If a second QoS parameter representing 150ms does not exist, then a second QoS parameter representing a latency less than 150ms (e.g., a third QoS parameter representing 130ms) is determined as the authorized second QoS parameter.

[0144] Optionally, the authorized second QoS parameter can be represented by a combination of the authorized first QoS parameter and the authorized third QoS parameter.

[0145] Similarly, taking the authorized first QoS parameter, authorized second QoS parameter, and authorized third QoS parameter to represent latency as an example, the latency represented by the authorized first QoS parameter is 100ms, and the latency represented by the authorized third QoS parameter is 50ms. Then, the latency represented by the authorized second QoS parameter is represented by the combination of {authorized first QoS parameter latency 100ms, authorized third QoS parameter latency 50ms}.

[0146] In this embodiment of the invention, the first terminal determines the authorized third QoS parameter in one of the following ways:

[0147] Method B1: Determined based on the authorized first QoS parameter and at least one second correspondence;

[0148] Method B2: Determined based on the first authorized QoS parameter and the second requested QoS parameter.

[0149] In mode B1, the authorized third QoS parameter is determined based on the authorized first QoS parameter and at least one second correspondence; the second correspondence is the correspondence between the first QoS parameter and the third QoS parameter.

[0150] The first terminal device determines the authorized third QoS parameters based on at least one second correspondence and the authorized first QoS parameters.

[0151] In one example, the first terminal device determines the authorized third QoS parameter based on the following three second correspondences: the correspondence between QoS parameter 1A and QoS parameter 3A, the correspondence between QoS parameter 1B and QoS parameter 3B, and the correspondence between QoS parameter 1C and QoS parameter 3C. QoS parameter 1A, QoS parameter 1B, and QoS parameter 1C are different first QoS parameters, and QoS parameter 3A, QoS parameter 3B, and QoS parameter 3C are different third QoS parameters. When the authorized first QoS parameter is QoS parameter 1B, the correspondence between QoS parameter 1B and QoS parameter 3B includes the authorized first QoS parameter, and the authorized third QoS parameter is determined to be QoS parameter 3B based on this correspondence.

[0152] In some embodiments, the at least one second correspondence is configured by the second network device to the first terminal device.

[0153] Optionally, the first terminal device receives the at least one second correspondence configured by the second network device.

[0154] Optionally, the second network device includes a PCF.

[0155] Optionally, such as Figure 10A As shown, before S802, the following steps are also performed:

[0156] S1001, the first terminal device receives at least one second correspondence configured by the second network device;

[0157] S1002. The first terminal device determines the authorized third QoS parameter based on at least one second correspondence and the authorized first QoS parameter.

[0158] exist Figure 10A In this invention, taking the implementation of S1001 before S801 as an example, the implementation of S1001 can also be after S801. The present invention does not limit the order of S1001 and S801.

[0159] After the first terminal device determines the authorized third QoS parameter based on the authorized first QoS parameter and at least one second correspondence, the implementation of S801 includes: determining the authorized second QoS parameter based on the authorized first QoS parameter and the authorized third QoS parameter.

[0160] Optionally, such as Figure 10B As shown, after step S1002, the following steps are also performed:

[0161] S1003, the first terminal device sends the combination of the authorized first QoS parameter and the authorized third QoS parameter to the second terminal device.

[0162] exist Figure 10B In this process, the first terminal device does not need to execute S802 and S803, but directly sends the combination of the authorized first QoS parameter and the authorized third QoS parameter to the second terminal device. At this time, the authorized second QoS parameter is represented by the combination of the authorized first QoS parameter and the authorized third QoS parameter.

[0163] In method B2, the authorized third QoS parameter is determined based on the authorized first QoS parameter and the requested second QoS parameter.

[0164] The first terminal device determines the authorized third QoS parameter based on the authorized first QoS parameter and the requested second QoS parameter, and determines the authorized second QoS parameter based on the authorized third QoS parameter and the authorized first QoS parameter.

[0165] The requested second QoS parameter characterizes the quality of service requirements between the second terminal device and the core network user plane anchor point.

[0166] In one example, taking latency as a QoS characteristic, if the authorized first QoS parameter represents a latency of 100ms and the requested second QoS parameter represents a latency of 150ms, then the authorized third QoS parameter represents a latency of less than or equal to 50ms. For example, the authorized third QoS parameter represents a latency of 30ms. However, the authorized third QoS parameter can also represent a latency greater than 150ms; this embodiment does not limit the magnitude of the authorized third QoS parameter's latency.

[0167] In method A3 above, the authorized second QoS parameter is determined based on the authorized first QoS parameter and the requested second QoS parameter.

[0168] The first terminal device determines the authorized second QoS parameters based on the authorized first QoS parameters and the requested second QoS parameters.

[0169] Optionally, the requested second QoS parameter is the same as the authorized second QoS parameter.

[0170] In one example, taking QoS characteristics as latency, the authorized first QoS parameter represents a latency of 100ms, and the requested second QoS parameter represents a latency of 150ms. Therefore, the latency represented by the authorized second QoS parameter is 150ms.

[0171] Optionally, the requested second QoS parameter is different from the authorized second QoS parameter.

[0172] In one example, taking QoS characteristics as latency, the authorized first QoS parameter represents a latency of 100ms, and the requested second QoS parameter represents a latency of 150ms. Therefore, the latency represented by the authorized second QoS parameter is 130ms.

[0173] In the above method A3, the authorized second QoS parameter is used to determine the authorized third QoS parameter together with the authorized first QoS parameter.

[0174] The first terminal device determines the authorized third QoS parameter based on the authorized first QoS parameter and the authorized second QoS parameter.

[0175] The authorized third QoS parameter is determined based on the authorized first QoS parameter and the authorized second QoS parameter.

[0176] In one example, taking QoS characteristics as latency, the first authorized QoS parameter represents a latency of 100ms, the second authorized QoS parameter represents a latency of 130ms, and the third authorized QoS parameter represents a latency of less than or equal to 30ms.

[0177] In some embodiments, when the authorized third QoS parameter is determined in mode B2, or the authorized second QoS parameter is determined in mode A3, the second terminal device sends the requested second QoS parameter to the first terminal device, and the first terminal device receives the requested second QoS parameter sent by the second terminal device.

[0178] Optionally, such as Figure 11A As shown, prior to S801, the following steps are also performed:

[0179] S1101, the first terminal device receives the second QoS parameter of the request sent by the second terminal device;

[0180] At this time, S802 can be implemented as follows: the first terminal device determines the authorized second QoS parameter and / or the authorized third QoS parameter based on the requested second QoS parameter and the authorized first QoS parameter.

[0181] Optionally, in S802, the first terminal device determines the authorized third QoS parameters based on the requested second QoS parameters and the authorized first QoS parameters. Optionally, the first terminal device may also determine the authorized second QoS parameters based on the authorized first QoS parameters and the authorized third QoS parameters.

[0182] Optionally, in S802, the first terminal device determines the authorized second QoS parameters based on the requested second QoS parameters and the authorized first QoS parameters. Optionally, the first terminal device may also determine the authorized third QoS parameters based on the authorized first QoS parameters and the authorized second QoS parameters.

[0183] In one example, after receiving the requested second QoS parameter and the authorized first QoS parameter sent by the first network device, the first terminal device determines the authorized third QoS parameter based on the authorized first QoS parameter and the requested second QoS parameter, and then determines the authorized second QoS parameter based on the authorized third QoS parameter.

[0184] In one example, after receiving the requested second QoS parameter and the authorized first QoS parameter sent by the first network device, the first terminal device determines the authorized second QoS parameter based on the authorized first QoS parameter and the requested second QoS parameter, and determines the authorized third QoS parameter based on the authorized second QoS parameter.

[0185] In some embodiments, the second QoS parameter of the request is used to determine the first QoS parameter of the request; the first QoS parameter of the request is used to determine the first QoS parameter of the authorization.

[0186] The first terminal device determines the first QoS parameter of the request based on the second QoS parameter of the request; the first terminal device sends the first QoS parameter of the request to the first network device; the first QoS parameter of the request is used by the first network device to determine the first QoS parameter of the authorization.

[0187] Optionally, the service quality requirement represented by the first QoS parameter may be higher than the service quality requirement represented by the second QoS parameter, or they may be the same. This embodiment of the invention does not limit the relationship between the service quality requirement represented by the first QoS parameter and the service quality requirement represented by the second QoS parameter.

[0188] Taking QoS features as latency as an example, the latency represented by the second QoS parameter of the request is greater than or equal to the latency represented by the first QoS parameter of the request.

[0189] In one example, the second QoS parameter requested represents a latency of 150ms, and the first QoS parameter requested represents a latency of 150ms.

[0190] In one example, the second QoS parameter requested represents a latency of 150ms, and the first QoS parameter requested represents a latency of 100ms.

[0191] The first network device receives the first QoS parameter requested; the first network device determines the first QoS parameter to be authorized based on the first QoS parameter requested.

[0192] Optionally, the first QoS parameter requested is the same as the first QoS parameter granted.

[0193] In one example, the latency represented by the first QoS parameter of the request is 100ms, and the latency represented by the first QoS parameter of the authorization is 100ms.

[0194] Optionally, the first QoS parameter requested is different from the first QoS parameter granted.

[0195] In one example, taking QoS parameters as latency, the latency represented by the first QoS parameter of the request is 100ms, and the latency represented by the first QoS parameter of the authorization is 80ms.

[0196] Optionally, such as Figure 11B As shown, after step S802, the following steps are also performed:

[0197] S1003, the first terminal device sends the combination of the authorized first QoS parameter and the authorized third QoS parameter to the second terminal device.

[0198] exist Figure 11B In this process, the first terminal device does not need to execute S803; it directly sends the combination of the authorized first QoS parameter and the authorized third QoS parameter to the second terminal device. At this time, the authorized second QoS parameter is represented by the combination of the authorized first QoS parameter and the authorized third QoS parameter.

[0199] like Figure 12 As shown, before S802, the following steps are also performed:

[0200] S1102. The first terminal device determines the requested first QoS parameter based on the requested second QoS parameter;

[0201] S1103, The first terminal device sends the requested first QoS parameters to the first network device.

[0202] Here, the first network device receives the first QoS parameters requested by the first terminal device, and determines the authorized first QoS parameters based on the requested first QoS parameters.

[0203] In some embodiments, the first terminal device sends the authorized third QoS parameters to the second terminal device. The second terminal receives the authorized third QoS parameters sent by the first terminal device.

[0204] In this embodiment of the invention, the first terminal device sends the authorized second QoS parameters and the authorized third QoS parameters to the second terminal device, so that the second terminal device can effectively control its own data transmission according to the QoS requirements of the PC5 interface and the end-to-end QoS requirements.

[0205] This invention also provides a wireless communication method, applied to... Figure 9 The second network device shown includes:

[0206] The second network device sends at least one first correspondence to the first terminal device; the first correspondence is at least a correspondence between a first QoS parameter and a second QoS parameter; the at least one correspondence is used to determine an authorized second QoS parameter with the authorized first QoS parameter; the authorized first QoS parameter represents the quality of service requirements between the first terminal device and the core network user plane anchor point; the authorized second QoS parameter represents the quality of service requirements between the second terminal device and the core network user plane anchor point; the second terminal device transmits data with the core network user plane anchor point through the first terminal device.

[0211] The second network device can obtain the quality of service requirements from the AF, determine the third QoS parameters based on the quality of service requirements, and create at least one first correspondence.

[0212] In some embodiments, the first correspondence is a correspondence between a first QoS parameter, a second QoS parameter, and a third QoS parameter; the at least one first correspondence is further used to determine an authorized third QoS parameter with the authorized first QoS parameter; the authorized third QoS parameter represents the quality of service requirements between the first terminal device and the second terminal device.

[0213] For a description of the first correspondence, please refer to the description of the first correspondence in method A1, which will not be repeated here.

[0214] The wireless communication method provided in the embodiments of the present invention will be further described below.

[0215] Example 1

[0216] The first network element of the core network (e.g., PCF) configures multiple sets of QoS mapping relationships (i.e., the first mapping relationship) to the Relay UE. Each set of QoS mapping relationships includes a first QoS parameter, a second QoS parameter, and a third QoS parameter. The first QoS parameter represents the quality of service between the Relay UE and the core network user plane anchor point, denoted by 5QI. The second QoS parameter represents the total quality of service between the Remote UE and the Relay UE's core network user plane anchor point through the Relay UE, which can be denoted by 5QI or PQI. The third QoS parameter represents the quality of service between the Relay UE and the Remote UE, denoted by PQI.

[0217] The second network element of the core network (e.g., SMF) sends the authorized first QoS parameters to the Relay UE. Based on the received first QoS parameters and the configuration of the QoS correspondence, the Relay UE determines the authorized second QoS parameters and the authorized third QoS parameters. It uses the authorized third QoS parameters to control the quality of service between the Relay UE and the Remote UE, and also sends the authorized second QoS parameters to the Remote UE. Thus, the Remote UE obtains the total authorized quality of service between the Remote UE and the Relay UE's core network user plane anchor point.

[0218] Here, the first authorized QoS parameter sent by the SMF to the Relay UE can be the first authorized QoS parameter queried from the PCF.

[0219] like Figure 13 As shown, it includes the following steps:

[0220] S1301, PCF sends at least one first correspondence to RelayUE;

[0221] The first correspondence includes: the first QoS parameter, the second QoS parameter, and the third QoS parameter.

[0222] S1302, SMF sends the first authorized QoS parameters to RelayUE;

[0223] The first authorized QoS parameter is the QoS parameter authorized between the RelayUE and the core network.

[0224] S1303, RelayUE determines the authorized second QoS parameters and the authorized third QoS parameters based on the first correspondence and the authorized first QoS parameters;

[0225] S1304. The RelayUE sends the authorized second QoS parameters and the authorized third QoS parameters to the Remote UE.

[0226] Example 2

[0227] Based on its application layer service requirements, the Remote UE determines the requested second QoS parameter, which is the total quality of service between the Remote UE and the Relay UE's core network user plane anchor point through the Relay UE. This can be represented by 5QI or PQI.

[0228] Based on the received second QoS parameter, the Relay UE determines the first QoS parameter, which is the quality of service between the Relay UE and the core network user plane anchor point, denoted as 5QI, according to its own implementation method, and sends it to the core network element (SMF or PCF) for authorization. The core network element then sends the authorized first QoS parameter to the Relay UE.

[0229] Based on the received authorized first QoS parameter and the received requested second QoS parameter, the Relay UE determines an authorized third QoS parameter for controlling the quality of service (QoS) between the Relay UE and the Remote UE, and then determines the authorized second QoS parameter. The authorized third QoS parameter is used to control the QoS between the Relay UE and the Remote UE, and the authorized second QoS parameter is also sent to the Remote UE. Thus, the Remote UE obtains the overall authorized QoS between the Relay UE and the Relay UE's core network user plane anchor point.

[0230] like Figure 14 As shown, it includes the following steps:

[0231] S1401. The Remote UE sends the requested second QoS parameters to the Relay UE;

[0232] S1402, Relay UE determines the requested first QoS parameter based on the requested second QoS parameter;

[0233] S1403, the Relay UE sends the requested first QoS parameter to the SMF;

[0234] S1404, SMF sends the first authorized QoS parameters to the Relay UE;

[0235] S1405, Relay UE determines the authorized second QoS parameter and the authorized third QoS parameter based on the authorized first QoS parameter;

[0236] S1406, The Relay UE sends the authorized second QoS parameters and the authorized third QoS parameters to the Remote UE.

[0237] In this embodiment of the invention, when a Remote UE with ProSe capability establishes a direct connection with a Relay UE through the PC5 interface and interacts with the external network through a PDU session established between the Relay UE and the 5G network, the Remote UE can not only obtain the quality of service (e.g., transmission latency of 50ms) of the PC5 interface from the Relay UE, but also understand the end-to-end quality of service (i.e., Uu+PC5 quality of service of 150ms) of its own transmission services. Therefore, it can control the transmission of its own service data according to the needs of the application layer.
