Claim 0:
1. A method at a user plane function node, the method comprising:
detecting that a user plane path is failed; and
sending a failure report of the user plane path to a control plane function node, wherein the failure report of the user plane path includes information of an Internet protocol address, a destination interface and a network instance of a sending node towards which the user plane path failure has been detected, wherein the destination interface identifies an access or core interface of the sending node; and
wherein the user plane function node comprises a packet data network gateway (PGW) user plane (PGW-U) node and the control plane function node comprises a PGW control plane (PGW-C) node, or the user plane function node comprises a serving gateway (SGW) user plane (SGW-U) node and the control plane function node comprises a SGW control plane (SGW-C) node, or the user plane function node comprises a User plane Function (UPF) node and the control plane function node comprises a Session Management Function (SMF) node.
