Real-Time MobileIPv6 Effort
Problem Definition
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.

Summary
• 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
