Abstract
In some Mobile IPv4 deployments, identifying the mobile node or the
mobility service subscriber is not enough to distinguish among the
multiple services possibly provisioned to the mobile node. The
capability to specify different services in addition to the mobile
node's identity can be leveraged to provide flexibility for mobility
service providers to provide multiple services within a single
mobility service subscription. This document describes a Service
Selection extension for Mobile IPv4 that is intended to assist home
agents to make specific service selections for their mobility service
subscriptions during the registration procedure.

1. Introduction
Mobile IPv4 [RFC3344] can identify mobile nodes in various ways,
including home addresses [RFC3344] and Network Access Identifiers
(NAIs) [RFC4282] [RFC2794]. In some Mobile IPv4 deployments,
identifying the mobile node (MN) or the mobility service subscriber
via a Proxy Mobile IPv4 client [LEUNG] (hereafter, the mobile node
and the Proxy Mobile IPv4 client are used interchangeably) is not
enough to distinguish among the multiple services possibly
provisioned to the mobile node.
The capability to specify different services in addition to the
mobile node's identity can be leveraged to provide flexibility for
mobility service providers to provide multiple services within the
same mobility service subscription. For example:
o Provide an enterprise data access for which the mobility service
provider hosts connectivity and mobility services on behalf of the
enterprise.
o Provide access to service domains that are otherwise not
accessible from public networks because of some mobility service
providers' business reasons.
o Provide simultaneous access to different service domains that are
separated based on policies of the mobility service provider.
o Enable easier policy assignment for mobility service providers
based on the subscribed services.

RFC 5446 Service Selection for MIPv4 February 2009
This document describes a Service Selection extension for Mobile IPv4
that is intended to assist home agents to make specific service
selections for their mobility service subscriptions during the
registration procedure. A Mobile IPv6-equivalent Service Selection
Mobility Option has been described in [RFC5149]. The service
selection may affect home agent routing decisions, Home Address
assignment policies, firewall settings, and security policies. When
the service selection is used, every Registration Request must
contain the Service Selection extension. The Service Selection
