In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described below. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the embodiments of the present application. protected range.

The QoS model of the 5G network is shown in Figure 2. In the 5G network, QoS control is controlled based on the granularity of the QoS flow (or called QoS data flow, QoS Flow). The session management network element SMF receives the information from the policy control network element PCF Policy and Charging Control (PCC) rules bind service data flows to QoS data flows. One QoS data flow can include one or more service data flows, and these service data flows have the same transmission time. Requirements such as latency and transmission bit error rate can be represented by the same 5G QoS indicator (5G QoS Index, 5QI), but they can have different bit rate requirements. When the SMF binds these service data streams to the QoS data stream, the value obtained by adding the code rates of the service data streams is taken as the code rate of the QoS data stream. The SMF sends the QoS (including 5QI, code rate information, etc.) requirements of the QoS data flow to the base station, and the base station schedules wireless resources to guarantee the QoS requirements of the QoS data flow.

In a mobile communication network, in order to be able to transmit user plane data, one or more QoS data streams need to be established, and different data streams correspond to different QoS parameters. As an important measure of communication quality (Communication quality), QoS parameters are usually used to indicate the characteristics of QoS data streams. QoS parameters can include but are not limited to: 5QI, Address Resolution Protocol (Address Resolution Protocol, ARP), guaranteed traffic bit rate ( Guaranteed Flow Bit Rate (GFBR), maximum flow bit rate (Maximum Flow Bit Rate, MFBR), maximum packet loss rate (Maximum Packet Loss Rate, including uplink UL and downlink DL), end-to-end packet delay budget (Packet Delay Budget , PDB), access network PDB (AN-PDB), packet error rate (Packet Error Rate), priority (Priority Level), average window (Averaging Window), resource type (Resource Type), maximum data burst (Maximum Data Burst Volume, MDBV), terminal aggregated maximum bit rate (UE-Aggregated Maximum Bit Rate, UE-AMBR), session aggregated maximum bit rate (Session-AMBR), etc.

The Filter (or service data flow (Service Data Flow, SDF) template) contains parameters describing the characteristics of the data packet, and is used to filter out specific data packets to bind to a specific QoS Flow. Here, the most commonly used Filter is IP (Internet Protocol, network protocol) quintuple, that is, source IP address, destination IP address, source port number, destination port number and protocol type.

The terminal and the core network user plane network element (user plane function) will form a filter according to the characteristic parameters of the data packet (such as the leftmost trapezoid and the rightmost parallelogram in Figure 2), which are used to filter the conforming data transmitted on the user plane Uplink or downlink data packets with packet characteristics, and bind them to a certain QoS data flow, that is, realize the mapping from data packets to QoS data flows.

Under the current mechanism, the QoS data flow is triggered by SMF. If the terminal wants to modify it, it needs to send a request message such as a PDU Session Modification Request (PDU Session Modification Request) to modify the QoS parameters of the relevant QoS Flow, data packet filter or Apply to create a new QoS Flow. That is to say, when a terminal application needs a new QoS, it needs to perform a session modification process, which must be agreed by the network. This process takes a long time, and there is no guarantee that the modification will be successful, so it will affect the behavior of the application. , that is, the application cannot accurately determine whether and how long it can use the desired communication quality, which will have a great impact on many real-time services, such as machine learning and neural network analysis.

When the QoS needs to be adjusted, both the terminal and the network side can trigger the PDU session modification process, thereby changing the QoS. There are also many situations that cause QoS changes, such as:

A base station handover has occurred;

Network congestion occurs (such as a sudden increase in the number of users);

The terminal moves into or out of a specific range (such as the service range of the edge server) and the like.

After in-depth research by the inventors of the present application, it is found that because some network elements such as access network equipment can identify the most fine-grained QoS data flow, only QoS guarantee at the QoS flow level can be performed, and one QoS flow can include multiple service data flows. Therefore, these network elements cannot identify service data flows. Based on this, various network nodes including access network devices such as base stations cannot perceive the services corresponding to the data packets in the data stream, and cannot reasonably allocate resources.

The solutions provided in the embodiments of the present application are mainly used to solve at least one of the above problems.

In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

According to the above method, the second network elements such as the user plane network element, the access network device, and the second terminal device will obtain the first information.

In this way, the base station establishes an air interface bearer according to the QoS parameter and determines the binding relationship between the air interface bearer and the QoS data flow. Moreover, based on the QFI and corresponding service information, the base station can also know the service information corresponding to each QoS data flow, realizing the ability of the base station to perceive service information. The base station may sense the service information corresponding to the uplink and/or downlink QoS data flow, which is not limited here.

S75: The session management network element sends the QFI and corresponding service information, as well as QoS data flow binding rules (such as QoS rules) to the terminal. In this way, the UE can perceive which service(s) the QoS data flow corresponds to. The terminal may perceive the service information corresponding to the uplink and/or downlink QoS data flow, which is not limited here.

Optionally, the session management network element can also combine the information sent to the base station and the terminal in S74 and S75 into one message, and send the message to the base station, that is, bind the QoS data flow in S75 to the rule and the QFI and the corresponding service Information, as a non-access stratum (Non Access Stratum, NAS) message, it is added to the message sent to the base station in S74, and the base station forwards the NAS message to the terminal through air interface signaling after receiving the message from the session management network element .

Application example four

In this application example, in the session establishment process or the session modification process, the first network element sends the first information to the second network element, where the first network element is a control plane network element of the core network, such as a session management network element, and the first network element The second network element includes a terminal, a base station, and a user plane network element. The first network element sends the model information of the first model to the second network element.

Specifically, the first model can be used to sense the uplink and/or downlink QoS data flow Whether the corresponding service information is the service information corresponding to the first model realizes the ability of the base station to sense the service information.

S83: The core network control plane network element sends the model information of the first model, corresponding service information, and QoS data flow binding rules (such as QoS rules) to the terminal. In this way, the UE can perceive which service(s) the QoS data flow corresponds to. The terminal may perceive the service information corresponding to the uplink and/or downlink QoS data flow, which is not limited here.
