Abstract

A method performed by a network node to change a transport path for a user plane session in a radio communications network. The path prolongs along a first part between an antenna endpoint of a network node and a Packet Processing Function (PPF) instance serving the network node and a second part between the PPF instance and a Core Network (CN) endpoint. The network node identifies available CN endpoints in a CN, available PPF instances in a Radio Access Network (RAN) and of available antenna endpoints in the RAN that are available for the user plane session and comprises a number of possible transport paths for the user plane session. When detecting a change event related to the user plane session, the network node controls whether or not to change the transport path to any of the a number of possible transport paths for the user plane session.
