IP Centric Heterogeneous Network
 Heterogeneous Network allows a variety of terminals, protocol, interconnectivity.
 Services provided seamlessly independent to access network.

Essence of “Beyond 3G”
Network comprising a variety of interworking access systems connected
to a common packet-based core network
 Various access systems (e.g. 3G cellular, a new radio Interface, W-LAN, Short range radio,
and wired access, etc.) will be connected via flexible core networks.
 User can be connected via a variety of different access systems to the networks.
 “Access Independent Service”: Network services are provided seamlessly through variety
of access supported with horizontal and vertical handover.
 “4G air interface” (100Mbps / 1G bps) would be an element of “Beyond 3G”
 “4G air interface” will not replace 3G radio, and it is complement to 3G radio and
other access subsystems
 MMD/IMS is essential toward “Beyond 3G”

Evolution of Air Interface -Enhanced CDMA2000-
Enhanced CDMA2000
 Improve system voice capacity (VoIP)
 Increase peak transmission rate to 100Mbps
(FL:100M~1Gbps, RL:50Mbps)




Improve spectrum efficiency
Reduce set-up time and round-trip delay
Reduce cost per bit
Backward compatibility with existing system
3GPP2 TSG-C has approved to initiate development of system
requirements and technology specifications for Enhanced CDMA2000
air interface based on proposal by 29 members (2005/5/20, Portland).

KDDI, by setting “mobile & IP” as a core competence of the
business and responding to the customers’ further reliance
and satisfaction, aims to become a
“Ubiquitous Solution Company”
