      DHCPv6 Prefix Delegation in Long-Term Evolution (LTE) Networks

Abstract

   As interest in IPv6 deployment in cellular networks increases,    several migration issues have been being raised; IPv6 prefix    management is the issue addressed in this document.  Based on the    idea that DHCPv6 servers can manage prefixes, we use DHCPv6 Prefix    Delegation to address such prefix management issues as an access    router offloading delegation of prefixes and release tasks to a    DHCPv6 server.  The access router first requests a prefix for an    incoming mobile node from the DHCPv6 server.  The access router may    next do stateless or stateful address allocation to the mobile node,    e.g., with a Router Advertisement or using DHCP.  We also describe    prefix management using Authentication, Authorization, and Accounting    (AAA) servers.
