2. Essence of “Beyond 3G”


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

Complementary Access System (from ITU-R Recommendation M.1645)

Services and applications

Download channel

Digital broadcast

New radio interface

WLAN type

Other entities

Cellular 2nd generation

Wireline xDSL

Packet-based core network

Short range connectivity

IMT-2000

IP Centric Heterogeneous Network


“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”

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.

Network comprising a variety of interworking access systems connected to a common packet-based core network

Essence of “Beyond 3G”


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).
