移動通信定位技術(shù)之比較

隨著移動通信的發(fā)展，在移動通信中提供除語音通信外的新的服務(wù)功能成為增長熱點，而定位服務(wù)是最重要的熱點之一，其原因與E-911條例要求所有移動網(wǎng)絡(luò)在運行時必須在一定的時限內(nèi)提供定位服務(wù)有關(guān)，該文通過對國外大量文獻(xiàn)的研究，詳細(xì)介紹了現(xiàn)有的各種移動通信定位技術(shù)，通過對各種定位方法進(jìn)行深入研究和比較后，指出了它們的實現(xiàn)方法及各自存在的優(yōu)點和不足。同時介紹了該技術(shù)領(lǐng)域的研究現(xiàn)狀，并對今后技術(shù)的發(fā)展方向提出了相應(yīng)的設(shè)想

By the mobile communication developing, location technology became new service of hotspot. More and more research organization have paid attention to this technology and it is necessary that mobile proprietor must provide location service before 2001 years. This paper it introduce all kinds of cell location techniques, advantage and disadvantage of every method is also said. In the end it point out the problems that have to be researched in the future and the trend of this technology.
