Moreover, one or more other operations may be added to the flow diagrams and one or more operations may be removed from the flow diagrams as directed by those skilled in the art.

In addition, the described embodiments are only some, but not all, of the embodiments of the present application. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, are intended to be within the scope of the present application.

It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.

In a 5G new radio access technology (new radio access technology, NR) network, a main part of quality of service (Quality of Service, qoS) control is mainly in a session management function (session management function, SMF), a next generation base station node (next generation Node Base station, gNB), and a terminal device (UE), a user plane function (UPF, user Plane Function) performs a corresponding operation only according to a control operation generated by the SMF, and there is no control right, and control of QoS by the 5G includes an uplink direction and a downlink direction, in which the SMF generates QoS control data to guide the UPF to implement service control, and the QoS control data generated by the SMF mainly performs quality control on a service between the UPF and the gNB.

In the prior art, in order to implement fast dynamic adjustment of Qos parameters in a 5G network for a specific service data flow, a protocol data unit (Protocol Data Unit, PDU) is generally established at a terminal at the beginning of the terminal accessing the 5G network, for example, a Qos parameter of a 5QI (5G Qos Indicator) is set, if the Qos parameter needs to be adjusted after the terminal accesses the 5G network, a cloud application is required to set a corresponding Qos parameter template in a policy control function (Policy Control Function, PCF) in advance, and an index value of the Qos parameter is given by a quality of service reference QosReference. It can be seen that the existing method needs to manually configure parameter templates, is complex in operation, and for cloud applications with flexible and changeable service requirements, a configuration template for all Qos parameters cannot be given in advance, i.e. a unified configuration template cannot be set.

In view of this, the embodiments of the present application provide a quality parameter adjustment method, which can complete Qos parameter adjustment for all 5G network elements, avoid manually configuring Qos parameter templates, and enable applications to flexibly initiate Qos parameter adjustment according to service requirements.

The embodiments of the present application are not limited in this regard.

3. Access Network (AN): the network access function is provided for authorized users in a specific area, and transmission tunnels with different qualities can be used according to the level of the users, the requirements of services and the like. 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 (3rd generation partnership project,3GPP) access technologies (e.g., wireless access technologies employed in 3G, 4G, or 5G systems) and non-third generation partnership project (non-3 GPP) access technologies. The 3GPP access technology refers to an access technology conforming to the 3GPP standard specification, and an access network employing the 3GPP access technology is referred to as a radio access network (radio access network, RAN), wherein an access network device in the 5G system is referred to as a next generation base station node (next generation Node Base station, gNB). The non-3GPP access technology refers to an access technology that does not conform to the 3GPP standard specification, for example, a null technology represented by an Access Point (AP) in WIFI.

An access network implementing access network functions based on wireless communication technology may be referred to as a radio access network (radio access network, RAN). The radio access network can manage radio resources, provide access service for the terminal, and further complete the forwarding of control signals and user data between the terminal and the core network.

An access network device may comprise, among other things, a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminals.

The CU implements part of the functions of the gNB, the DU implements part of the functions of the gNB, for example, the CU implements the functions of a radio resource control (radio resource control, RRC), a packet data convergence layer protocol (packet data convergence protocol, PDCP) layer, and the DU implements the functions of a radio link control (radio link control, RLC), a medium access control (media access control, MAC), and a Physical (PHY) layer. Since the information of the RRC layer may eventually become information of the PHY layer or be converted from the information of the PHY layer, under this architecture, higher layer signaling, such as RRC layer signaling, may also be considered to be transmitted by the DU or by the du+cu. It is 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 an access network (radio access network, RAN), or may be divided into access network devices in a Core Network (CN), which is not limited herein.

For example, in a 6G network, some or all of the individual network elements may follow the terminology in 5G, possibly by other names, etc. The description is unified herein, and will not be repeated.

Fig. 2 is a flowchart of a method for adjusting qos parameters according to an embodiment of the present application, where an execution body of the embodiment may be a NEF in the network architecture shown in fig. 1. As shown in fig. 2, the method includes:

s101, the NEF receives a quality of service Qos parameter adjustment request for a target application, which is sent by a cloud server.

The Qos parameter adjustment request includes: for the identification of the target service of the target application, the target application may be deployed on the terminal device, the target application may deploy a plurality of services, taking the target application as a video application as an example, and the plurality of services deployed by the video application may include, but is not limited to: 480P video play, 360P video play, etc., that is, the multiple services deployed by the video application may be differentiated by video resolution.

In an actual usage scenario, a user may input a service adjustment instruction for a target service through a target application, where the service adjustment request includes an identifier of the target service, so that the cloud server may receive the service adjustment instruction, and respond to the service adjustment instruction, and send a quality of service Qos parameter adjustment request for the target application to the NEF, where the Qos parameter adjustment request includes an identifier of the target service for the target application, for example, an identifier of 480P video for the video application.

S102, NEF determines a target Qos parameter corresponding to the target application according to the identification of the target application, and assigns a value to the target Qos parameter according to the identification of the target service to obtain a target Qos parameter value.

The NEF receives a Qos parameter adjustment request for a target application sent by a cloud server, can analyze the Qos parameter adjustment request to obtain an identification of the target application and an identification of a target service for the target application, then determines a target Qos parameter corresponding to the target application according to the identification of the target application, and assigns a value to the target Qos parameter according to the identification of the target service to obtain a target Qos parameter value.

That is, the target Qos parameter value is obtained by assigning a target Qos parameter corresponding to a target service, where the target Qos parameter corresponding to the target service includes, but is not limited to: the resource Allocation keeps priority (Allocation/Retension priority, ARP), priority processing level of service data flow, average window, maximum data burst, uplink guaranteed bandwidth, downlink guaranteed bandwidth, uplink maximum bandwidth, downlink maximum packet loss rate, uplink maximum packet loss rate, message delay budget and packet error rate.

Optionally, each service and Qos parameters have a certain mapping relationship, the NEF may determine a target Qos parameter corresponding to the target service by querying the mapping relationship according to the identifier of the target service, and assign a value to the target Qos parameter of the target service according to the service requirement of the target service, so as to obtain a target Qos parameter value.

S103, the NEF sends a policy modification request to the policy control function PCF, wherein the policy modification request comprises a target Qos parameter value, so that the PCF informs the target base station, the terminal equipment and the user plane function UPF of configuring the target Qos parameter through the session management function SMF.

After the NEF determines the target Qos parameter value corresponding to the identifier of the target service of the target application, a policy modification request can be sent to the PCF, wherein the policy modification request comprises the target Qos parameter value, so that the PCF informs the target base station, the terminal equipment and the UPF of configuring the target Qos parameter through the SMF, that is, the target base station, the terminal equipment and the UPF adjust the current Qos parameter value of the target Qos parameter of the network to the target Qos parameter value so as to optimize network resources, and the policy modification request can be flexibly initiated by the target application according to service requirements when the Qos parameter is adjusted, and a Qos parameter template is not required to be configured, so that the operation is simple.

It should be noted that, the PCF may send a session policy update request to the SMF, where the SMF analyzes the session policy update request to obtain a target Qos parameter value, and encapsulates the target Qos parameter value according to a contract manner with the target base station, the terminal device, and the UPF, and sends the target Qos parameter value to the target base station, the terminal device, and the UPF, respectively, through a contract transmission protocol, so that the target base station, the terminal device, and the UPF adjust the Qos parameter value of the current network according to the target Qos parameter value.

In some embodiments, after the SMF informs the target base station, the terminal device, and the UPF of adjusting the Qos parameter value of the current network according to the target Qos parameter value, a session policy update response may also be fed back to the PCF, where the session is a protocol data unit (Protocol Data Unit, PDU) session, and it can be seen that the Qos parameter adjustment scheme of the present application works in the scenario of PDU session creation and PDU session modification, that is, when both the PDU session is created or the PDU session is modified, the adjustment of the network Qos parameter is involved.

Optionally, the policy modification request is used for requesting the PCF to generate policy and charging control PCC rules according to the target Qos parameter value, and notifying the target base station, the terminal device, and the UPF of the PCC rules through the SMF.

The NEF sends a policy modification request to the policy control function PCF, where the policy modification request is used to request the PCF to generate a policy and charging control (Policy Control and Charging, PCC) rule according to the target Qos parameter, that is, the PCF parses the policy modification request sent by the NEF to obtain a target Qos parameter value, then generates a PCC rule according to the target Qos parameter value, and notifies the target base station, the terminal device, and the UPF of the PCC rule via the SMF.

In the method for adjusting Qos parameters of the present embodiment, the network application open function NEF receives a Qos parameter adjustment request for a target application sent by a cloud server, where the Qos parameter adjustment request includes: the NEF determines a target Qos parameter corresponding to the target application according to the identification of the target application and assigns a value to the target Qos parameter to obtain a target Qos parameter value according to the identification of the target service, and sends a policy modification request to a policy control function PCF, wherein the policy modification request comprises the target Qos parameter value, so that the PCF can inform a target base station, terminal equipment and a user plane function UPF of configuring the target Qos parameter through a session management function SMF, thereby avoiding manual configuration of a Qos parameter template, being simple to operate, and supporting the application to flexibly initiate the adjustment of the Qos parameter according to service requirements.

It should be noted that, for the existing index value of Qos parameter given by QosReference, where QosReference embeds a nominal value of 5G quality of service indication (5G QoS Indicator,5QI), the nominal value of 5QI is used to indicate a priority handling level, an average window, a maximum data burst, a downlink maximum packet loss rate, an uplink maximum packet loss rate, a packet delay budget and an error packet rate of a service data stream, and after the priority handling level, the average window, the maximum data burst, the downlink maximum packet loss rate, the uplink maximum packet loss rate, the packet delay budget and the error packet rate of the service data stream are assigned by the NEF, the corresponding nominal value of 5QI is obtained by the query protocol, and after the priority handling level, the average window, the maximum data burst, the downlink maximum packet loss rate, the uplink maximum packet loss rate, the corresponding nominal value of 5QI is obtained according to the nominal value of 5QI, and after the assignment of the uplink maximum packet loss rate, the downlink maximum packet loss rate, the uplink packet loss rate, the message delay budget and the error packet loss rate are adjusted to the target Qos parameter value, and the policy is generated, and the uplink bandwidth is modified, and the maximum Qos request is requested and the uplink bandwidth is modified.

One possible implementation of step S102 described above is described below in connection with the example of fig. 3.
