1. A system comprising a User Equipment (UE), and
an Access and Mobility Management Function (AMF) comprising
a processor configured to:
receive, from the UE, an initial registration request message that comprises an indication that the UE has a capability of support for simultaneous slice usage constraints;
generate a first registration accept message, for transmission to the UE, that indicates slice compatibility information for each configured network slice of a set of configured network slices for the UE, wherein the slice compatibility information for each configured network slice indicates whether or not other configured network slices of the set of configured network slices are compatible with the configured network slice for simultaneous registration;
receive, from the UE, an additional registration request message to request registration on a set of requested network slices, wherein the set of requested network slices is a subset of the set of configured network slices, and wherein the set of requested network slices is compatible for simultaneous registration according to the slice compatibility information;
register the UE to the set of requested network slices; and
generate an additional registration accept message for transmission to the UE indicating the UE is registered to the set of requested network slices;
wherein the UE comprises a processor configured to generate the additional registration request message based on the slice compatibility information, such that the set of requested network slices is compatible for simultaneous registration according to the slice compatibility information;
wherein the additional registration request message only requests registration on network slices that are compatible for simultaneous registration according to the slice compatibility information.
