Abstract
A method of 5G session management (5GSM) state mapping is proposed when interworking. For each PDU session in 5GSM state of PDU SESSION active, PDU SESSION MODIFICATION PENDING, or PDU SESSION INACTIVE PENDING, UE maps the PDU session to a PDN connection in 4G ESM state BEARER CONTEXT ACTIVE. For any other PDU session in 5GSM state of PDU SESSION inactive, or PDU SESSION ACTIVE PENDING, UE maps the PDU session to a PDN connection in 4G ESM state BEARER CONTEXT INACTIVE.
