Real-Time MobileIPv6 EffortReal-Time MobileIPv6 Effort
Define architectural framework and required mobile (node/router) endpoint and access router protocol
functionality to
support seamless handoff for real-time IP streams across heterogeneous
(wireless access) technologies
using Mobile IP (v6) technology that considers AAA, Security and QoS during handoff.

SummarySummary
• Multimedia services are based on IP.
• Multiple access technologies are currently in use.
• Multimedia mobility at IP layer is required to permit mobility across multiple types of access networks.
• Various standards groups leading to develop multimedia mobility solutions that cross the access technology boundaries:
IETF, MWIF, and others
