OTDOA location determining technology for universal intelligent positioning system (UIPS) implementation in Malaysia

Various location determining techniques have been proposed for location based services (LBS) such as cell identification (cell ID), observed time difference of arrival (OTDOA), enhanced observed time difference (E-OTD), network multipath analysis and assisted global positioning system (A-GPS). This paper presents the development work by simulating OTDOA based location determining technology (LDT) with integration to universal intelligent position system (UIPS) implementation in Malaysia's Telco network. The concept of UIPS for GSM and UMTS networks offers the key players of the entire mobile services value chain in Malaysia to benefit through its integration. It is expected with the usage of UIPS, content providers (CP) can connect easily to Telcos and offer variety of LBS services. It is hope that with UIPS, major key players to continuously promote LBS to make it a successful consolidated effort for navigation, information search and emergency tracking. Challenges faced on different geographical terrains calls for further study on random survey to construct a trained database with noise/loss models for accuracy improvement. This is to complement any fall back contingency.
