Mobility Management
Mobile IP-GSM Mobility Interworking
- Mobile IP-GSM authentication interworking
- Scalability of Mobile IP/hierarchical agents
Multicast support for mobility
- Alternative approach for mobility based on M/C addresses
- Exploit multicast routing to reach mobile nodes without explicit handoff
- Combine with real-time delivery of voice and video
Generalized redirection agents
- Policy-based redirection: e.g., 1-800 service, email to pagers, etc.
- Redirection agents collocated with multicast tree branching points
