Abstract

During PDN connection establishment in the EPC, a UE and a session management entity (SME) (e.g., PGW-C+SMF) exchange information. In case the SME supports more than one S-NSSAI, before the SME provides an S-NSSAI to the UE, the SME should check such that the selected S-NSSAI is among the UE's subscribed S-NSSAIs by retrieving the Subscribed S-NSSAI from a UDM using, for example, the Nudm_SDM_Get service operation.
