Claim 4:
5. The method of claim 1, further comprising:
in response to determining that the UE has the active session registration for the second network slice, selectively rejecting, by the UDM node, the session registration request based on a combination of the first network slice access-control policy, the second network slice access-control policy, and a third network slice access-control policy, wherein the third network slice access-control policy specifies priority values associated with one or more network slices, and wherein selectively rejecting the session registration request comprises:
in response to determining that the first network slice and the second network slice are mutually exclusive based on the first and second network slice access-control policies, determining, by the UDM node, whether the first network slice has a priority value lower than a priority value of the second network slice based on the third network slice access-control;
in response to determining that the first network slice has the priority value lower than the priority value of the second network slice, deregistering, by the UDM node, the active session registration for the second network slice; and
allowing, by the UDM node, the session registration request after deregistering the active session registration.
