2. 5 November 2005IETF-642 Goals  Introduce IPv6 deployment scenario that suits for WiBro  Provide issues that should be considered when deploying IPv6 over WiBro

3. 5 November 2005IETF-643 Why IPv6 over WiBro?  WiBro service in 2006 (IPv4)  IPv6 over WiBro is in the near future  Advantages for IPv6 over WiBro □ Enhanced support for Mobility by MIPv6 □ Increasing number of mobile devices in broadband networks

4. 5 November 2005IETF-644 Scenario Phase 1Phase 2Phase 3 Description WiBro service based on IPv4 Starts offering IPv6 service Provide stable IPv6 service Mobile StationIPv4-only - IPv4-only - IPv4/IPv6 Dual Stack - IPv4-only - IPv4/IPv6 Dual Stack - IPv6-only Access Network IPv4/IPv6 Dual Stack Backbone Network IPv4 - IPv4 - MPLS tunneling IPv4/IPv6 Dual Stack
