Abstract

A method is performed by a network entity of a wireless communication network. A first PDU session is established for a wireless terminal (UE) using a first NodeB base station (MgNB) and a first user plane function entity (UPF1). A second PDU session is established for the wireless terminal (UE) using a second NodeB base station (SgNB) and a second user plane function entity (UPF2). The first and second PDU sessions are established for the wireless terminal (UE) using the first and second NodeB base stations so that the first and second PDU sessions are provided concurrently using dual connectivity DC to provide redundant data paths for communication of data for the wireless terminal (UE) through the wireless communication network.
