                     Distributed Mobility Anchoring
            draft-ietf-dmm-distributed-mobility-anchoring-03

Abstract

   This document defines distributed mobility anchoring in terms of the
   different configurations, operations and parameters of mobility
   functions to provide different IP mobility support for the diverse
   mobility needs in 5G Wireless and beyond.  A network or network slice
   may be configured with distributed mobility anchoring functions
   according to the needs of mobility support.  In the distributed
   mobility anchoring environment, multiple anchors are available for
   mid-session switching of an IP prefix anchor.  To start a new flow or
   to handle a flow not requiring IP session continuity as a mobile node
   moves to a new network, the flow can be started or re-started using a
   new IP prefix which is allocated from and is therefore anchored to
   the new network.  For a flow requiring IP session continuity, the
   anchoring of the prior IP prefix may be moved to the new network.
   The mobility functions and their operations and parameters are
   general for different configurations.  The mobility signaling may be
   between anchors and nodes in the network in a network-based mobility
   solution.  It may also be between the anchors and the mobile node in
   a host-based solution.  The mobile node may be a host, but may also
   be a router carrying a network requiring network mobility support.
