Further, the Network architecture further includes AN Access Network device (R) AN, a terminal device (UE), and a data Network element (DN). The UE may be connected to the AMF, (R) AN may be connected to the AMF, the (R) AN may be connected to the UPF, the UPF may be connected to the SMF, the DN, the AMF may be connected to SMF, UDM, PCF, NSSF and AUSF, respectively, and the SMF may be connected to PCF and UDM, respectively.

In 4G, the AUSF may be replaced with an authentication, authorization, and accounting (authentication, authorization, accounting server, AAA) server, and in future communications such as 6G, the AUSF may still be the AUSF, or other name network element supporting authentication functions, as the invention is not limited.

A Core Network (CN) serves as an interface provided to the DN by a bearer network to provide communication connection, authentication, management, communication, and bearer completion for data traffic, etc. for the terminal device. In the network architecture shown in fig. 1, the core network functions are divided into a user plane function and a control plane function. The user plane functions are mainly responsible for forwarding of packet data packets, qoS control, etc. The control plane function is mainly responsible for user registration authentication, mobility management, packet forwarding policy issuing to the UPF, qoS control policy, etc. The control plane functions mainly include an access and mobility management function (core access and mobility management function, AMF) network element and a session management function (session management function, SMF) 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 functions. N4 is a connection between the SMF network element and the user plane function, and is used for transferring 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 the function of user plane and DN, N7 is the connection between SMF network element and PCF, N8 is the connection between AMF network element and UDM network element, N10 is the connection between UDM network element and SMF network element, N11 is the connection between AMF network element and SMF network element, N12 is the connection between AUSF network element and AMF network element, N13 is the connection between AUSF network element and UDM, N14 is the interface between AMF, N15 is the connection between AMF network element and PCF network element, and N22 is the connection between NSSF network element and AMF network element.

After the UE accesses the 5G network through the Uu port, a QoS flow is established under the control of the SMF to perform data transmission, and a transmission quality parameter of the QoS flow includes a 5G QoS identifier (5G QoS Identifier,5QI). The 5QI may be mapped to a range of QoS characteristics such as latency, bit error rate, scheduling priority, etc.

In one example, the 5QI is shown in table 1, with a value of 66 for 5QI, characterizing the following QoS characteristics: priority 20, delay 100ms, error rate 10 ^-2 。

Table 1 example 5qi

5QI Value	Priority level	Time delay	Error rate
66	20	100ms	10 ^-2

As shown in fig. 2, the UE with ProSe capability can also directly communicate with another UE with ProSe capability through a PC5 interface, where the PC5 interface is the interface of the UE so far. And establishing a PC5 QoS data flow which can ensure corresponding QoS requirements between two UE to transmit service data, thereby ensuring the service quality of service in PC5 communication. QoS parameters for a PC5 QoS data flow include a PC5 5G QoS identification (PC 5qi, PQI), which may be mapped to a series of QoS characteristics such as latency, bit error rate, scheduling priority, etc.

In one example, as shown in table 2, the value of 5QI is 95, characterizing the following QoS characteristics: priority 2, delay 200ms and error rate 10 ^-2 。

Table 2 PQI example

PQI	Priority level	Time delay	Error rate
95	2	200ms	10 ^-2
58	4	100ms	10 ^-2
57	5	25ms	10 ^-1

As shown in fig. 2, UE1 and UE2 include three PC5 unicast links, where two PC5 unicast links are included between application a on UE1 and application a on UE2, one data stream of the PC5 unicast link is PC5 QoS data stream #1, one data stream of the PC5 unicast link is PC5 QoS data stream #2, one data stream of the PC5 unicast link is included between application B on UE1 and application B on UE2, and one data stream is PC5 QoS data stream #3. One of the UE1 and the UE2 is a Remote UE, and the other is a Relay UE.

AS shown in fig. 3, when one UE has both an external data network connected through a 5G network and ProSe capability, this UE may act AS a Relay UE, and another remote UE with ProSe capability may establish a direct connection with a Relay UE through a PC5 interface, and establish a PDU session with a 5G network (including NG-RAN and 5 GC) through the Relay UE, and interact with an application server (Applation Service, AS) of the external network through the established PDU session.

In the related art, when a Remote UE with Prose capability establishes a direct connection with a Relay UE through a PC5 interface and interacts with an external network through a PDU session established by the Relay UE and a 5G network, the PCF controls the service quality from the Relay UE to the external network, for example, the transmission delay is 100ms, the Relay UE can determine the service quality on the PC5 interface according to its configuration, for example, the transmission delay is 50ms, but the Remote UE only obtains the service quality of the PC5 interface from the Relay UE (for example, the transmission delay is 50 ms), and does not know the end-to-end service quality of the own transmission service (that is, the service quality of uu+pc5 is 150 ms), so that it cannot know whether the own service data is transmitted according to the requirement of an application layer.

Based on the above-described problems, the present invention provides a wireless communication method, and the wireless communication method of the embodiment of the present invention can be applied to various communication systems, for example: global system for mobile communications (Global System of Mobile communication, GSM), code division multiple access (Code Division Multiple Access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) systems, general packet radio service (General Packet Radio Service, GPRS), long term evolution (Long Term Evolution, LTE) systems, LTE frequency division duplex (Frequency Division Duplex, FDD) systems, LTE time division duplex (Time Division Duplex, TDD), universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), worldwide interoperability for microwave access (Worldwide Interoperability for Microwave Access, wiMAX) communication systems, or 5G systems, and the like.
