SELECTING USER PLANE FUNCTION BASED ON INTERNET PROTOCOL STACK CAPABILITIES

Abstract

The present disclosure is directed to systems and methods for selecting a user plane function (UPF) from among a plurality of available UPFs at least partially based on an internet protocol version of the UPF matching an IP version capability of a base station. A base station will communicate its IP version capability to a mobility network function (e.g., an access mobility function (AMF)) so that session establishment requests forwarded to a session management network function or gateway (e.g., a session management function (SMF)) can include the base station's IP version capability—allowing it to be used by the session management network function for selecting a UPF.
