PDN connection supports interworking to 5GS

A method of handling a Packet Data Network (PDN) connection to support interworking to 5G system (5GS) is proposed. In a first novel aspect, both UE and the network stores mapped 5GSM parameters of a corresponding Protocol Data Unit (PDU) session when inter-system change from S1 (4G, EPS) mode to A/...

Zusammenfassung:A method of handling a Packet Data Network (PDN) connection to support interworking to 5G system (5GS) is proposed. In a first novel aspect, both UE and the network stores mapped 5GSM parameters of a corresponding Protocol Data Unit (PDU) session when inter-system change from S1 (4G, EPS) mode to A/Gb (2G) mode or Iu (3G, UMTS) mode. In a second novel aspect, the PDN connection is enable to support interworking to 5GS, and the UE is allowed to allocate and indicate the PDU session ID by using the bearer resource modification procedure in EPS, or the mapped 5GSM parameters can be provided and modified in 2G/3G system.
