Abstract:
A method for handling PDU session handover procedure collision in a next generation NG/5G system is proposed. Both network-triggered and UE-triggered PDU session handover procedures can occur at the same time. If Paging or Notification for PDU session handover comes before UE initiated MO PDU session establishment procedure for PDU session handover, then UE should avoid sending the PDU session establishment request for PDU session handover but only send the service request as a response to paging. On the other hand, if Paging or Notification for PDU session handover comes after UE initiated MO PDU session establishment procedure for PDU session handover, then UE should avoid sending the service request for PDU session handover but proceed with the PDU session establishment procedure as a response to paging.
