Watanabe, “Evolution Towards Beyond 3G”, June 27, 2005, KDDI Proprietary 5 IP Centric Heterogeneous Network Heterogeneous Network allows a variety of terminals, protocol, interconnectivity. Services provided seamlessly independent to access network. Download channel Services and applications New radio interface Wireline Digital broadcast Packet-based core network xDSL Cellular 2nd WLAN type generation IMT-2000 Short range connectivity Other entities Complementary Access System (from ITU-R Recommendation M.1645) F. Watanabe, “Evolution Towards Beyond 3G”, June 27, 2005, KDDI Proprietary 6 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” F. Watanabe, “Evolution Towards Beyond 3G”, June 27, 2005, KDDI Proprietary 7 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).
