In a new radio access technology (NR) network of 5G, a main part of Quality of Service (QoS) control is mainly performed in a Session Management Function (SMF), a next generation Base station Node (gNB), and a terminal device (UE), a User Plane Function (UPF) performs corresponding operations only according to control operations generated by the SMF, and has no control right, the QoS control of 5G includes an uplink direction and a downlink direction, in the downlink direction, the SMF generates QoS control data to instruct the UPF to implement Service control, and the SMF generates QoS control data to perform Quality control on services between the UPF and the gNB.
Currently, to implement specific service-oriented Data flow, fast and dynamically adjusting Qos parameters in a 5G network is usually performed by establishing a Protocol Data Unit (PDU) at a terminal at the beginning of accessing the 5G network, for example, a Qos parameter of a 5QI standard (5G Qos Indicator), and if the Qos parameter needs to be adjusted after the terminal accesses the 5G network, a cloud application needs to set a corresponding Qos parameter template in a Policy Control Function (PCF) in advance, and give an index value of the Qos parameter by a quality of service reference Qos reference. It can be seen that, in the existing method, parameter templates need to be configured manually, which is complicated in operation, and for cloud applications with flexible and variable service requirements, configuration templates for all Qos parameters cannot be given in advance, that is, unified configuration templates cannot be set.

The access network may be an access network employing different access technologies. There are two types of current radio access technologies: third generation partnership project (3 GPP) access technologies such as the radio access technologies employed in 3G, 4G or 5G systems and non-third generation partnership project (non-3GPP) access technologies. The 3GPP access technology refers to an access technology meeting 3GPP standard specifications, and an access network adopting the 3GPP access technology is referred to as a Radio Access Network (RAN), where an access network device in a 5G system is referred to as a next generation Base station (gNB).

Since the information of the RRC layer eventually becomes or is converted from the information of the PHY layer, the higher layer signaling, such as the RRC layer signaling, may also be considered to be transmitted by the DU or the DU + CU under this architecture. It is to be understood that the access network device may be a CU node, or a DU node, or a device comprising a CU node and a DU node. In addition, the CU may be divided into access network devices in a Radio Access Network (RAN), or may be divided into access network devices in a Core Network (CN), which is not limited herein.
