Abstract

Information regarding disjoint transport paths of a transport network is acquired (S501). Based on the acquired information, a user plane node of a plurality of user plane nodes of a core network is selected (S503), from which at least one of the disjoint transport paths is reachable, wherein the user plane node is selected as an endpoint of at least one tunnel out of at least two tunnels to be established for a packet data unit, PDU, session to carry traffic between the user plane node and an access node of an access network, wherein the at least two tunnels are to be set up by mapping the at least two tunnels to the disjoint transport paths.
