"IEEE 802.21 Mobility Services Framework Design (MSFD)", Telemaco Melia, Gabor Bajko, Subir Das, Nada Golmie, Juan Zuniga, 30-Jan-09. ( bytes)

This document describes a mobility services framework design (MSFD) for the IEEE 802.21 Media Independent Handover (MIH) protocol that addresses identified issues associated with the transport of MIH messages. The document also describes mechanisms for mobility service (MoS) discovery and transport layer mechanisms for the reliable delivery of MIH messages. This document does not provide mechanisms for securing the communication between a mobile node (MN) and the mobility service (MoS). Instead, it is assumed that either lower layer (e.g., link layer) security mechanisms, or overall system-specific proprietary security solutions, are used.

"Dynamic Host Configuration Protocol (DHCPv4 and DHCPv6) Options for IEEE 802.21 Mobility Services (MoS) Discovery", Gabor Bajko, Subir Das, 4-May-09. ( bytes)

This document defines new Dynamic Host Configuration Protocol (DHCPv4 and DHCPv6) options that contain a list of IP addresses and a list of domain names that can be mapped to servers providing IEEE 802.21 type of Mobility Service (MoS)[MSFD]. These Mobility Services are used to assist a mobile node (MN) in handover preparation (network discovery) and handover decision (network selection). The services addressed in this document are the Media Independent Handover Services defined in [IEEE802.21].

"Locating IEEE 802.21 Mobility Servers using DNS", Gabor Bajko, 13-Jul-09. ( bytes)

This document defines application service tags that allow service location without relying on rigid domain naming conventions, and DNS procedures for discovering servers which provide IEEE 802.21 [IEEE802.21] defined Mobility Services. Such Mobility Services are used to assist a Mobile Node (MN) supporting IEEE 802.21 [IEEE802.21], in handover preparation (network discovery) and handover decision (network selection). The services addressed by this document are the Media Independent Handover Services defined in [IEEE802.21].

"Fast Handovers for Proxy Mobile IPv6", Hidetoshi Yokota, Kuntal Chowdhury, Rajeev Koodli, Basavaraj Patil, Frank Xia, 13-Jul-09. ( bytes)

Mobile IPv6 (MIPv6) [RFC3775] provides a mobile node with IP mobility when it performs a handover from one access router to another and fast handovers for Mobile IPv6 (FMIPv6) [RFC5268bis] are specified to enhance the handover performance in terms of latency and packet loss. While MIPv6 (and FMIPv6 as well) requires the participation of the mobile node in the mobility-related signaling, Proxy Mobile IPv6 (PMIPv6) [RFC5213] provides IP mobility to mobile nodes that either have or do not have MIPv6 functionality without such involvement. Nevertheless, the basic performance of PMIPv6 in terms of handover latency and packet loss is considered not any different from that of MIPv6. When the fast handover is considered in such an environment, several modifications are needed to FMIPv6 to adapt to the network- based mobility management. This document specifies the usage of Fast Mobile IPv6 (FMIPv6) when Proxy Mobile IPv6 is used as the mobility management protocol. Necessary extensions are specified for FMIPv6 to support the scenario when the mobile node does not have IP mobility functionality and hence is not involved with either MIPv6 or FMIPv6 operations.

"Transient Binding for Proxy Mobile IPv6", Marco Liebsch, Ahmad Muhanna, Oliver Blume, 8-Jun-09. ( bytes)

This document specifies a mechanism which enhances Proxy Mobile IPv6 protocol signaling to support the creation of a transient binding cache entry which is used to optimize the performance of dual radio and active single radio handover. This mechanism is applicable to the mobile node's inter-MAG handover while using a single interface or different interfaces. The handover problem space using the Proxy Mobile IPv6 base protocol is analyzed and the use of transient binding cache entries at the local mobility anchor is described. The specified extension to the Proxy Mobile IPv6 protocol ensures optimized forwarding of downlink as well as uplink packets between mobile nodes and the network infrastructure and avoids superfluous packet forwarding delay or even packet loss.
