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.

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. Korhonen & Nilsson Informational [Page 2] 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 SelectionShow full document text
