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 a smart selection
   and combination of access and core network paths that can dynamically
   adapt to changing network conditions.  This document presents the
   problem statement and proposes solution principles.  It specifies the
   requirements and architecture for the multi-access management
   services framework that can be used to 1) flexibly select the best
   combination of access and core network paths for uplink and downlink,
   as well as 2) determining the user plane treatment and traffic
   distribution over the selected links ensuring better network
   efficiency and enhanced application performance.
