Internet Engineering Task Force (IETF) S. Das Request for Comments: 6153 Telcordia Technologies Category: Standards Track G. Bajko ISSN: 2070-1721 Nokia February 2011 DHCPv4 and DHCPv6 Options for Access Network Discovery and Selection Function (ANDSF) Discovery Abstract This document defines new Dynamic Host Configuration Protocol (DHCPv4 and DHCPv6) options to enable a mobile node to discover Access Network Discovery and Selection Function (ANDSF) entities in an IP network. ANDSF is being developed in the Third Generation Partnership Project (3GPP) and provides inter-system mobility policies and access-network-specific information to the mobile nodes (MNs).

Introduction Access Network Discovery and Selection Function (ANDSF) is being defined in 3GPP [3GPPTS23.402] to provide necessary network discovery and selection assistance data to the mobile nodes for multi-access network scenarios where 3GPP access-network level solutions are not sufficient for the mobile nodes to perform network discovery and selection of non-3GPP networks. The information provided by ANDSF contains inter-system mobility policies and access-network-specific data to assist the mobile node with performing the inter-system handover. This set of information can either be provisioned in the mobile node by the home operator or provided to the mobile node (MN) dynamically by the ANDSF over the S14 reference point as defined in [3GPPTS23.402] and [3GPPTS24.302]. In 3GPP, the ANDSF is located either in the subscriber's home operator or visited network and needs to be known to the MN or discovered by the MN. According to [3GPPTS23.402] and [3GPPTS24.302], the ANDSF is discovered through interaction with the Domain Name Service function or the DHCP server function. This document defines new DHCPv4 and DHCPv6 options called the ANDSF IP Address Options, which allow the MN to locate an ANDSF server.
