Abstract

A network node () of a radio access network (RAN) of a wireless communication network () provides user plane security by establishing a secure tunnel between first and second tunnel endpoints () that will handle respective protocol layers of a same protocol stack for a Data Radio Bearer (DRB) () that is dedicated to user plane traffic and has yet to be established. Establishing the secure tunnel comprises exchanging an inner Internet Protocol (IP) address and an outer IP address of each of the endpoints () between the endpoints ().
