Abstract

   In some Mobile IPv6 deployments, identifying the mobile node or the
   mobility service subscriber is not enough to distinguish between
   multiple services possibly provisioned to the said mobile node and
   its mobility service subscription.  A capability to specify different
   services in addition to the mobile node identity can be leveraged to
   provide flexibility for mobility service providers on provisioning
   multiple services to one mobility service subscription.  This
   document describes a Service Selection Mobility Option for both
   conventional Mobile IPv6 and Proxy Mobile IPv6 that is intended to
   assist home agents to make a specific service selection for the
   mobility service subscription during the binding registration
   procedure.

RFC 5149              Service Selection for MIPv6          February 2008

1.  Introduction

   Mobile IPv6 [2] can identify mobile nodes in various ways, including
   home addresses [2], Network Access Identifiers (NAIs) [6][7], and
   credentials suitable for the Internet Key Exchange Protocol version 2
   (IKEv2) [10].  In some Mobile IPv6 deployments, identifying the
   mobile node or the mobility service subscriber via a Proxy Mobile
   IPv6 client [5] (hereafter, the mobile node and the Proxy Mobile IPv6
   client are used interchangeably) is not enough to distinguish between
   multiple services possibly provisioned to the said mobile node and
   its mobility service subscription.

   The capability to specify different services in addition to the
   mobile node 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
      provider's 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 and quality of service assignment for
      mobility service providers based on the subscribed services.

   o  In the absence of a specifically indicated service, the home agent
      MUST act as if the default service, plain Internet access, had
      been requested.  There is no absolute requirement that this
      default service be allowed to all subscribers, but it is highly
      RECOMMENDED in order to avoid having normal subscribers employ
      operator-specific configuration values in order to get basic
      service.

   This document describes a Service Selection Mobility Option for
   Mobile IPv6 that is intended to assist home agents to make specific
   service selections for the mobility service subscription during the
   binding registration procedure.  The service selection may affect
   home agent routing decisions, Home Address or Home Network Prefix
