Service isolation method and device based on 5G network

The invention provides a service isolation method and device based on a 5G network, and the method and device are applied to a base station, and the base station communicates with a core network and a terminal. The method comprises the following steps: acquiring a plurality of predefined dynamic network slices from a core network; wherein each dynamic network slice has a corresponding identifier, and the identifier is used for identifying a service quality level; respectively defining a corresponding parameter group based on the identifier of each dynamic network slice; wherein each parameter group has a corresponding scheduling strategy, and each scheduling strategy is respectively used for realizing a corresponding service demand; and in response to the service request, determining a target terminal, obtaining a target service demand of the target terminal, determining a target scheduling policy according to the target service demand, and accessing the target terminal to a target dynamic network slice corre
