Features of “PacketOne” network

Packet Radio Access

– 95B 64Kbps, 14.4Kbps

(down/up stream)

– 1X 144Kbps, 64Kbps

(down/up stream)

– EV-DO 2.4Mbps, 153Kbps

(down/up stream)(to be provided 2003)

Seamless Mobility Support

– Continuous data communication while in movement – Continuous data communication through 95B, 1x, and EV-DO RANs

IP communication

– using IP protocol from Mobile Node to Server

  • In PacketOne network, continuous data communications are supported while in

movement.

  • 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 assigned

to MN before H/O. KDDI’s network sports two IP address assign methods.

Mobile Node IP address assignment

1. Carrier assign type

  • IP address is assigned by KDDI dynamically from pooled addresses when

mobile node connect to ‘PacketOne’ network.

  • In case of MN H/O, session management function assign the same IP

address before H/O.

2. User assign type

  • IP address is assigned by user’s home radius server.
  • Each MN assigned the same its own IP address every time connecting to

PacketOne network.

  • ‘EZweb’ service uses this type.

Two types of IP address assignment methods are available.

IPv6 Network to support user demands

Consumer Demands Home Access from Outside Enterprise Demands Probe car Info (ITS) Push information to sales representatives outside

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 push

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
