Quality-of-Service Option for Proxy Mobile IPv6
2014Co-Authors: Pierrick Seite, Marco Liebsch, Sri Gundavelli, Hidetoshi Yokota, Jouni KorhonenAbstract:This specification defines a new Mobility option, the Quality-of- Service (QoS) option, for Proxy Mobile IPv6. This option can be used by the local Mobility Anchor and the mobile access gateway for negotiating Quality-of-Service parameters for a mobile node's IP flows. The negotiated QoS parameters can be used for QoS policing and marking of packets to enforce QoS differentiation on the path between the local Mobility Anchor and the mobile access gateway. Furthermore, making QoS parameters available on the mobile access gateway enables mapping of these parameters to QoS rules that are specific to the access technology and allows those rules to be enforced on the access network using access-technology-specific approaches.

Diameter Support for Proxy Mobile IPv6 Localized Routing
2014Co-Authors: Glen Zorn, Jouni KorhonenAbstract:In Proxy Mobile IPv6, packets received from a Mobile Node (MN) by the Mobile Access Gateway (MAG) to which it is attached are typically tunneled to a Local Mobility Anchor (LMA) for routing. The term "localized routing" refers to a method by which packets are routed directly between an MN's MAG and the MAG of its Correspondent Node (CN) without involving any LMA. In a Proxy Mobile IPv6 deployment, it may be desirable to control the establishment of localized routing sessions between two MAGs in a Proxy Mobile IPv6 domain by requiring that the session be authorized. This document specifies how to accomplish this using the Diameter protocol.

ipv4 traffic offload selector option for proxy mobile ipv6
RFC, 2013Co-Authors: Rajeev Koodli, Sri Gundavelli, Xingyue Zhou, Jouni KorhonenAbstract:This specification defines a new Mobility option, the IPv4 Traffic Offload Selector option, for Proxy Mobile IPv6. This option can be used by the local Mobility Anchor and the mobile access gateway for negotiating IPv4 traffic offload policy for a Mobility session. Based on the negotiated IPv4 traffic offload policy, a mobile access gateway can selectively offload some of the IPv4 traffic flows in the access network instead of tunneling back to the local Mobility Anchor in the home network.

Access Network Identifier (ANI) Option for Proxy Mobile IPv6
2012Co-Authors: Mark Grayson, Jouni Korhonen, Sri Gundavelli, Rajesh Pazhyannur, Kent K. LeungAbstract:The local Mobility Anchor in a Proxy Mobile IPv6 (PMIPv6) domain is able to provide access-network- and access-operator-specific handling or policing of the mobile node traffic using information about the access network to which the mobile node is attached. This specification defines a mechanism and a related Mobility option for carrying the access network identifier and the access operator identification information from the mobile access gateway to the local Mobility Anchor over Proxy Mobile IPv6.

PMIPv6 inter-working with WiFi access authentication
2012Co-Authors: Marco Liebsch, Pierrick Seite, Sri GundavelliAbstract:Proxy Mobile IPv6, the IETF's protocol for network-based Mobility management, requires a completed and successful authentication of the mobile node before it is registered at the Mobility Anchor. This document describes inter-working between access authentication mechanisms, such as IEEE 802.1X, and the Proxy Mobile IPv6 protocol to enable trusted WiFi access to a network-based Mobility management domain. Furthermore, the use of authentication method specific identifiers for unique identification of mobile nodes during setup and maintenance of their Mobility session is described, following recommendations of related standards organizations, such as 3GPP and the WiMAX Forum.

Proxy Mobile IPv6 (PMIPv6) Localized Routing Problem Statement
2011Co-Authors: Marco Liebsch, Sangjin JeongAbstract:Proxy Mobile IPv6 is the IETF standard for network-based Mobility management. In Proxy Mobile IPv6, mobile nodes are topologically Anchored at a Local Mobility Anchor, which forwards all data for registered mobile nodes. The set up and maintenance of localized routing, which allows forwarding of data packets between mobile nodes and correspondent nodes directly without involvement of the Local Mobility Anchor in forwarding, is not considered. This document describes the problem space of localized routing in Proxy Mobile IPv6.

Proxy Mobile IPv6 Localized Routing
2010Co-Authors: Paulo Ferrer Loureiro, Marco LiebschAbstract:The IETF specified Proxy Mobile IPv6 as protocol for network-based Mobility management. In Proxy Mobile IPv6, mobile nodes are attached to the network through Mobility Access Gateways and registered with a Local Mobility Anchor. Traffic from and to the mobile node traverses the mobile node's Local Mobility Anchor, irrespective of the location of the mobile node's corresponding communication endpoint. This document specifies a protocol extension to Proxy Mobile IPv6 which allows the set up and maintenance of an optimized routing path between two communicating mobile nodes' Mobility Access Gateways without traversing the mobile nodes' Local Mobility Anchor(s). The protocol component of a rendezvous control point ensures stable maintenance of routing states during handover in scenarios with multiple Mobility Anchors, where states for the two communication endpoints is distributed between these Anchors.

Mobile data offloading: A host-based distributed Mobility management approach
IEEE Internet Computing, 2014Co-Authors: Jong-hyouk Lee, Kamal Deep Singh, Jean-marie Bonnin, Sangheon PackAbstract:The increasing use of mobile devices has resulted in an explosion in mobile Internet traffic. To cope with this growth, mobile network architectures are becoming flatter, and IP Mobility support protocols must evolve along with them. The authors propose an IP Mobility support protocol that doesn't rely on a single Mobility Anchor, but rather uses distributed Mobility Anchors to overcome existing protocols' limitations while providing selective data offloading. They highlight their protocol's main features and strengths through qualitative comparisons and simulations.

distributed local Mobility Anchor architecture for large scale Mobility management
Personal Indoor and Mobile Radio Communications, 2013Co-Authors: Zhiwei Yan, Jong-hyouk Lee, Jianfeng GuanAbstract:In this paper, we introduce a deployment strategy to support large scale Mobility management based on Proxy Mobile IPv6 (PMIPv6). As a centralized Mobility management protocol, PMIPv6 employs a single-handed Mobility Anchor, Local Mobility Anchor (LMA), to maintain the Mobility context and routing status of all registered mobile nodes in a localized domain. However, this single-handed Mobility Anchor will suffer with ever-increasing mobile Internet traffic. We propose a distributed local Mobility Anchor architecture with new prefix and address management schemes and then present a Mobility management procedure with operational aspects. In the proposed architecture, the registration message is always routed to the closest LMA thanks to the anycast routing. The other LMAs create the direct host route to the serving Mobility Anchor Gateway (MAG) for the optimized packet transmission. We also analyze the proposed architecture's performance in terms of scalability, robustness, and efficiency. The results demonstrate that the state synchronization of the proposed architecture induces extra signaling cost during the handover, however, the optimized route established by it can save more cost when the PMIPv6 service is adopted in the large-scale environment.

network architecture and fast handover scheme using Mobility Anchor for umts wlan interworking
Asia-Pacific Network Operations and Management Symposium, 2007Co-Authors: Incheol Kim, Sungkuen Lee, Taehyung Lim, Eallae Kim, Jinwoo ParkAbstract:UMTS-WLAN interworking has attracted many research efforts because each of UMTS and WLAN can maximize its capability in service provisioning. Through UMTS-WLAN internetworking, users can be offered the most suitable services according to service area and service provider can reduce network building and maintenance costs. In this paper, we propose a network architecture and fast handover scheme using Mobility Anchor (MA) for UMTS-WLAN interworking. MA is provided at the boundary between GGSN and PDG, under the 3GPP-proposed interworking reference model. Such MA can enable authentication and session establishment before L2 handover of the mobile node, so that seamless and fast vertical handover could be possible. Through computer simulation using OPNET for the performance measurement, the efficiency and validity of the proposed scheme has been examined.
