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).

1. 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.
