The present invention faces the issue of improving isolation of network slices in network slicing deployments where a centralized User Data Management, which includes subscription information for all users in a network with a plurality of network slices, is shared by the plurality of network slices. To solve this issue, the present invention provides for a distributed slice data repository for handling slice selection data for users equipped with a user equipment, UE, in a network that includes a plurality of network slices. This distributed slice data repository has: a slice user data repository, SDR, per network slice basis and including subscription information for each UE to be served by the network slice, and a slice selection repository, SSR, which is external to any network slice, shared by the plurality of network slices, and only includes slice selection data for every UE in the network.
