Dynamic Host Configuration Protocol (DHCPv4 and DHCPv6) Options for
IEEE 802.21 Mobility Services (MoS) Discovery
Abstract
This document defines new Dynamic Host Configuration Protocol (DHCPv4
and DHCPv6) options that contain a list of IP addresses and a list of
domain names that can be mapped to servers providing IEEE 802.21 type
of Mobility Service (MoS) (see RFC 5677). These Mobility Services
are used to assist a mobile node (MN) in handover preparation
(network discovery) and handover decision (network selection). The
services addressed in this document are the Media Independent
Handover Services defined in IEEE 802.21.

1. Introduction
IEEE 802.21 [IEEE802.21] defines three distinct service types to
facilitate link layer handovers across heterogeneous technologies:
a) Information Services (IS)
IS provides a unified framework to the higher-layer entities
across the heterogeneous network environment to facilitate
discovery and selection of multiple types of networks existing
within a geographical area. The objective is to help the higher-
layer mobility protocols acquire a global view of heterogeneous
networks and perform seamless handover across these networks.
b) Event Services (ES)
Events may indicate changes in state and transmission behavior of
the physical, data link, and logical link layers, or predict state
changes of these layers. The Event Service may also be used to
indicate management actions or command status on the part of the
network or some management entity.
c) Command Services (CS)
The command service enables higher layers to control the physical,
data link, and logical link layers. The higher layers may control
the reconfiguration or selection of an appropriate link through a
set of handover commands.
