The present document investigates and evaluates possible solutions to improve the DCN selection of DECOR feature by
adding assistance from the UE.
The assistance information from the UE is intended to reduce signalling required to select a DCN associated with the
UE. It shall complement the Rel-13 DECOR selection mechanism. All 3GPP RATs are supported i.e. E-UTRAN,
UTRAN, GERAN and NB-IOT. The enhancement can also improve the separation between dedicated core networks by
avoiding redirections between DCNs i.e. avoiding UEs accessing DCN in which it is not allowed. It is advantageous if
the solution works when the UE change serving PLMN.
