Background technique

With the growth of EPC (4G core network) services, traditional EPS gateways have gradually produced some constraints. User data stream processing is concentrated in the Public Data Network (PDN) egress gateway, which causes the gateway device to be cumbersome and has poor scalability. The control plane of the gateway is highly coupled with the user plane, which is not conducive to the smooth evolution of the core network. The user plane expansion demand frequency is higher than the control plane, and the tight coupling causes the control plane user plane to synchronously expand, and the device update period is short, resulting in an increase in the composite cost. Network layer data forwarding is difficult to identify users and service features. It can only be forwarded according to the Quality of Service (QoS) delivered by the upper layer, resulting in inefficient use of network resources. It is difficult to finely control the data flow according to users and service characteristics. In addition, a large number of strategies require manual configuration, resulting in increased management complexity and high operating costs. Therefore, the control functions in the packet domain gateway need to be separated from the forwarding functions to meet the needs of network development and market applications.

In the related art, the gateway (Gate Way, GW) control plane and the user plane are separated in a non-roaming scenario, and each processing unit based on the User Plane Function (UPF) directly binds the address, and the load reported by the UPF is the whole of the UPF.
