7IP mobility support• In PacketOne network, continuous data communications are supported while inmovement.
• In case of mobile node H/O, MN and PDSN establish a new ppp link. HA and PDSN
make a new mobile IP tunnel.
• To provide the continuity of IP communication, the same IP address must be assignedto MN before H/O. KDDI’s network sports two IP address assign methods.

Mobile Node IP address assignment
Two types of IP address assignment methods are available.
1.

Carrier assign typenn

2.

IP address is assigned by KDDI dynamically from pooled addresses whenmobile node connect to ‘PacketOne’ network.
In case of MN H/O, session management function assign the same IPaddress before H/O.

User assign typennn

IP address is assigned by user’s home radius server.
Each MN assigned the same its own IP address every time connecting toPacketOne network.
‘EZweb’ service uses this type.

Consumer Demands Home Access from Outsidev6

Enterprise Demands

probe
push

Motivation:
Home network appliances will be available by 2003.
(use of IPv6 necessary to solve address shortage problems)Solution:
IPv6/IPv4 dual-stack broadband (ADSL/FTTH/CATV) service
IPv6 access from browser phones via IPv4/v6 translator
Native IPv6 access from mobile/PHS terminals

Probe car Info (ITS)
Push information to sales representatives outside
Motivation:needs to access mobile terminals directly
Solution:
IP push by static IPv6 address
IPv6 push to mobile terminals (via IPv6 gateway)
Native IPv6 access to mobile/PHS terminals
