What is “IMT-2000”

• IMT-2000 (Internet Mobile Telecommunications-2000) is the personalized global multi-media service, which makes it possible to use the one mobile phone or user access card service by unifying all the various mobile telephone system specs that previously runs by each country.

• The peculiarities of this service are to provide the global roaming service and multi-media communications such as, high quality of sound, image and Internet.

• ITU-R, ITU-T, and other organizations for standardization agree on the global plural standardization for global roaming services, which connects immobile & mobile communications and private & public communication lines

• This is “ 3rd Generation Mobile Communication System”


Services of IMT-2000 System

• 高品質、高速率的多媒體資料傳輸– Packet-switched 傳輸服務 (144kbps~384kbps~2Mbps)– 依據不同的 QoS 要求，進行特定的傳輸功能設定– 提供較佳的通訊品質，有效降低通訊中斷率– 提供具彈性的多樣化雙向傳輸服務– 提供更合理的傳輸服務收費機制

• 高度頻譜利用效率– Wideband CDMA 接取– 動態無線資源分配– 嚴密、快速的功率控制

• 無遠弗屆的覆蓋率– 彈性的基地台配置

IMT-2000 Short History (1/2)

• 1988 : RACE I (Research of Advanced Communication Technologies in Europe) program– Basic research work

• 1992-1995 : RACE II program– CDMA-based CODIT (Code Division Testbed)– TDMA-based ATDMA (Advanced TDMA Mobile Access) air inter

face• 1995 : ACTS (Advanced Communication Technologies

and Service) Program– FRAMES (Future Radio Wideband Multiple Access System) pro

ject• FMA1 : Wideband TDMA• FMA2 : Wideband CDMA


IMT-2000 Short History (2/2)

• 1997 : ARIB Evaluation approval by ITU

• 1998 early : 3GPP creation (formally start at the end of 1998)

• 1998 June : ETSI selection– 15 RTT proposals were submitted ( 10 for Terrestrial, 5

for Satellite)

• 1998 Sep. : 3GPP2 creation

• 1999 July : 3G harmonization

• 2000 May : Five terrestrial RTT standards are formal approval by ITU


IMT-2000 Terrestrial RTT Standardization

• One single global Wideband CDMA standard with three optional modes– IMT-MC (CDMA2000), Multi-Carrier– IMT-DS (W-CDMA), Direct Spread– IMT-TC (TD-SCDMA), Time-Code

• One single global TDMA standard– IMT-SC (UWC-136), Single-Carrier

• One standard for indoor services– IMT-FT (DECT), Frequency Time
