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

As interest in IPv6 deployment in cellular networks increases, severalmigration issues have been being raised; IPv6 prefix management is theissue addressed in this document. Based on the idea that DHCPv6servers can manage prefixes, we use DHCPv6 Prefix Delegation toaddress such prefix management issues as an access router offloadingdelegation of prefixes and release tasks to a DHCPv6 server. Theaccess router first requests a prefix for an incoming mobile node fromthe DHCPv6 server. The access router may next do stateless or statefuladdress allocation to the mobile node, e.g., with a RouterAdvertisement or using DHCP. We also describe prefix management usingAuthentication, Authorization, and Accounting (AAA) servers.
