2) Full sharing mode: all slices share the network element function of the core network, so that the method is suitable for industrial slices with low isolation.

3) Full exclusive mode: the complete industry special core network is almost equivalently constructed, the safety isolation is highest, but the cost is also highest. The method is suitable for high-isolation slicing scenes.
