Abstract  Abstract

A method of handling PDU session identity (PSI) mismatch for PDU session procedures is proposed. In case a user equipment (UE) receives a 5G session management (5GSM) message in which the PSI value indicates that the PDU session is in 5GSM state PDU SESSION INACTIVE, the UE stays in its current 5GSM state for the PDU session and responds with a 5GSM status message including a 5GSM cause 43 Invalid PDU session identity to reduce signaling and UE handling effort. In case the UE receives a 5GSM message in which the PSI value is a reserved or an assigned value, the UE stays in its current 5GSM state for the PDU session and ignores the 5GSM message to reduce signaling.
