Development of IMT2000 dual-mode terminal platform

This paper describes the development of a prototype IMT2000 dual-mode terminal, which is designed for the 3rd generation overseas market that will commence at the beginning of 2003. Globally, the 3rd generation mobile terminal has to support both current 2nd generation GSM/GPRS and WCDMA as 3rd generation, a requirement that has mainly arisen from operators' demands. On the other hand, suppliers need to design this dual-mode terminal in the size of a single mode terminal to be competitive. It is important to have a platform for the development of both Hardware and Software and to verify each function before producing the LSI so that we can have an attractive terminal in the market in terms of size, cosmetic, quality, price and launch terminals on the market earlier than competitors. It is possible to verify the functionality of Layer 3 and below by using this platform, which also provides the flexibility to comply with any change in 3GPP (3rd Generation Partnership Project) and GSM (Global System for Mobile communications) specification by using PLDs. We have completed the test for independent function of both GSM and WCDMA and are now testing the major objective of dual mode function.
