The core network (CN), as the bearer network, provides the interface to the DN, and provides communication connection, authentication, management, communication for terminal equipment, and completes the bearer of data services. In the network architecture shown in FIG. 1 , the core network functions are divided into user plane functions and control plane functions.

After the UE accesses the 5G network through the Uu port, it establishes a QoS flow for data transmission under the control of the SMF. The transmission quality parameters of the QoS flow include the 5G QoS Identifier (5QI). 5QI can be mapped to a series of QoS features such as delay, bit error rate, scheduling priority and so on.

In an example, 5QI is shown in Table 1, and the value of 5QI is 66, which represents the following QoS characteristics: the priority is 20, the delay is 100 ms, and the bit error rate is 10 ⁻² .

Table 1 5QI example

5QI Value5QI Value	优先级priority	时延delay	误码率bit error rate
6666	2020	100ms100ms	10 ^-2 10 ^-2

As shown in FIG. 2 , a 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 up to now. A PC5 QoS data flow that can guarantee the corresponding QoS requirements is established between the two UEs to transmit service data, so as to ensure the service quality of the service in the PC5 communication. The QoS parameters of PC5QoS data flow include PC5 5G QoS identifier (PC5 5QI, PQI). PQI can be mapped to a series of QoS features such as delay, bit error rate, scheduling priority, etc.

In an example, as shown in Table 2, the value of 5QI is 95, which represents the following QoS characteristics: the priority is 2, the delay is 200ms, and the bit error rate is 10 ⁻² .

Table 2 PQI example

PQIPQI	优先级priority	时延delay	误码率bit error rate
9595	22	200ms200ms	10 ^-2 10 ^-2
5858	44	100ms100ms	10 ^-2 10 ^-2
5757	55	25ms25ms	10 ^-1 10 ^-1

As shown in FIG. 2, UE1 and UE2 include three PC5 unicast links, wherein, between application A on UE1 and application A on UE2, there are two PC5 unicast links, and the data flow of one PC5 unicast link It is PC5QoS data flow #1, the data flow of a PC5 unicast link is PC5QoS data flow #2, and there is a PC5 unicast link between application B on UE1 and application B on UE2, and the data flow is PC5QoS data flow #3. Among them, one of UE1 and UE2 is a Remote UE, and the other is a Relay UE.

As shown in Figure 3, when a UE has both the connection to the external data network through the 5G network and the ProSe capability, the UE can act as a relay UE, and another remote UE with ProSe capability can establish a connection with the Relay UE through the PC5 interface Connect directly, and establish a PDU session with the 5G network (including NG-RAN and 5GC) through the Relay UE, and interact with the 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 the Relay UE through the PC5 interface, and interacts with the external network through the PDU session established between the Relay UE and the 5G network, the PCF controls the quality of service from the Relay UE to the external network, such as The transmission delay is 100ms, and the Relay UE can determine the quality of service on the PC5 interface according to its own configuration. For example, the transmission delay is 50ms, but the Remote UE only obtains the quality of service of the PC5 interface from the Relay UE (for example, the transmission delay is 50ms), It does not know the end-to-end service quality of its own transmission service (that is, the service quality of Uu+PC5 is 150ms), so it is impossible to know whether its own service data is transmitted according to the requirements of the application layer.
