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
