Title: 5gsm handling on invalid pdu session

IPC: H04W68/00
Filed: 2019-10-16
Abstract: A method of handling invalid PDU session during handover procedure between non-3GPP access and 3GPP access in a mobile communication network is proposed. A UE establishes a PDU session over a first RAT, and then tries to handover the PDU session from the first RAT to a second RAT. However, at the network side, the PDU session over the first RAT does not exist anymore and the network considers the PDU session to be invalid. The network thus sends a PDU session establishment reject message back to the UE, with a 5GSM status message cause value #54 indicating "PDU session does not exist". At the UE side, the PDU session over the first RAT is still valid (e.g., not inactive). In order to resynchronize with the network, the UE performs a PDU session release procedure to release the PDU session over the first RAT.
