An operator may choose to deploy one (or more) dedicated core networks within a PLMN with each core network
dedicated for specific type(s) of subscriber. The present document studies and evaluates architectural enhancements
required to support dedicated core networks. The specific dedicated core network that serves a UE is selected based on
subscription information and operator configuration, without requiring the UEs to be modified.
The technical report covers both assignment of dedicated core network nodes and maintaining the association during
mobility. Roaming and network sharing aspects of dedicated core network, and impacts on procedures such as CSFB,
SRVCC and rSRVCC will be studied.
Dedicated core networks may be in the PS domain or CS domain or both.
