Abstract

   In multiconnectivity scenarios, the end-user devices can
   simultaneously connect to multiple networks based on different access
   technologies and network architectures like WiFi, LTE, DSL.  Both the
   quality of experience of the users and the overall network
   utilization and efficiency may be improved through the smart
   selection and combination of access and core network paths that can
   dynamically adapt to changing network conditions.  This document
   presents a unified problem statement and introduces a solution for
   managing multiconnectivity.  The solution has been developed by the
   authors based on their experiences in multiple standards bodies
   including the IETF and 3GPP, but is not an Internet Standard and does
   not represent the consensus opinion of the IETF.  This document
   describes the requirements, solution principles, and an architectural
   framework that aims to provide best performance while being easy to
   implement in a wide variety of multiconnectivity deployments.  It
   specifies the protocol multi-access management to: 1) flexibly select
   the best combination of access and core network paths for uplink and
   downlink; as well as 2) determine the user plane treatment and
   traffic distribution over the selected links ensuring network
   efficiency and application performance.
