A method and an apparatus for managing resources of a network slice are disclosed. In the method, a slice management apparatus obtains independent decision results of a plurality of network slices respectively; if the independent decision results of the plurality of network slices are not completely consistent, determines final decision results for the network slices based on the independent decision results of the plurality of network slices; and sends the final decision results to a virtualized infrastructure manager VIM. The final decision results are used to instruct to allocate resource of a first network slice in the plurality of network slices to a second network slice in the plurality of network slices.
