Network Working Group J. Korhonen Request for Comments: 5149 U. Nilsson Category: Informational TeliaSonera V. Devarapalli Azaire February 2008 Service Selection for Mobile IPv6 Status of This Memo This memo provides information for the Internet community. It does not specify an Internet standard of any kind. Distribution of this memo is unlimited. 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.

Informational [Page 1] 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 assignment policies, firewall settings, and security policies. The Service Selection option should be used in every Binding Update thatShow full document text
