IEEE 802.21 Mobility Services Framework Design (MSFD)

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.
