【正文】 s evolution, the network intellectualized degree unceasingly is also promoting. The intelligent network and the intelligent service constitutes in the future the persontoperson munication basic condition. Higher bandFrom the first generation of simulation mobile phone, to the second generation of numeric move network, to future third generation mobile munication system, the network use39。s influence Are the same with correspondence other domains, a wireless data traffic most important driving influence from Internet. According to the recent research, two year Europe39。Mobile munication technological development tendencyAbstract: This article elaborated the modern mobile munication technology six big most recent development tendency in detail: The network service39。關(guān)于移動智能網(wǎng)的研究,早在1995年就已開始,剛開始并沒有具體的標(biāo)準(zhǔn)協(xié)議出現(xiàn),各廠商各自制定了自己的標(biāo)準(zhǔn),并且據(jù)此進行了不少的研究工作,如Alcatel、Nortel、Ericsson等都先后推出了自己的初期產(chǎn)品。用戶第一次能夠在他們所在的任何地方無線接收和撥打電話。在個人多媒體世界里,話音郵件和電子郵件被傳送到移動多媒體信箱中。 在過去的十年里,傳統(tǒng)的生活方式已經(jīng)在迅速改變,人們更經(jīng)常性地移動,職業(yè)和個人生活之間的分界變得模糊,人們需要不分時間、地點訪問很重要的信息。 無線數(shù)據(jù)業(yè)務(wù)的主要驅(qū)動力在于用戶的應(yīng)用。根據(jù)最近的研究,未來兩年歐洲的因特網(wǎng)用戶數(shù)量將翻一番。業(yè)務(wù)、技術(shù)、市場三者之間是一種互動的關(guān)系,伴隨著用戶對數(shù)據(jù)、多媒體業(yè)務(wù)需求的增加,網(wǎng)絡(luò)業(yè)務(wù)向數(shù)據(jù)化、分組化發(fā)展,移動網(wǎng)絡(luò)必然走向?qū)拵Щ?第三代移動系統(tǒng),即IMT2000,是一種真正的寬帶多媒體系統(tǒng),它能夠提供高質(zhì)量寬帶綜合業(yè)務(wù)并實現(xiàn)全球無縫覆蓋。s Mobitex and GSM system39。 The short note will bee has the picture and the video frequency content electronic postcard。s relaxation will make the puter net, the telemunication network, the television network and so on to speed up bes in one friendly, the wide band IP technology bees the support which and the bining site three nets fuse. Future network to the wide band, the intellectualization, the personalized direction will develop, forms the unified prehensive wide band munications network, and gradually evolution for by nucleus. The heart backbone level and meets the skeleton which eight positions, the service and the network separate. 8 / 8。s mercial value and the consumer market obtained the proof, the whole world moved the market to grow by the unusual speed. The mobile munication evolution39。 Other one kind is the packet switching migration data traffic, like Motorola39。六、網(wǎng)絡(luò)趨于融合,走向統(tǒng)一1998年4月,ITUT在新推出的智能網(wǎng)能力集一2標(biāo)準(zhǔn)中描述了移動接入的功能實體,稱為CAMEL phase2標(biāo)準(zhǔn)。EDGE(增強數(shù)據(jù)速率GSM改進模式)使用修改過的GSM調(diào)制方式來實現(xiàn)超過300kbit/s的數(shù)據(jù)速率。關(guān)鍵詞： 移動通信 Internet 無線數(shù)據(jù) IMT2000 智能網(wǎng) 網(wǎng)絡(luò)融合一、移動通信的意義所在 無線數(shù)據(jù)——生機無限當(dāng)前移動數(shù)據(jù)通信發(fā)展迅速,被認為是移動通信發(fā)展的一個主要方向。話音呼叫將與實時圖像相結(jié)合,產(chǎn)生大量的可視移動電話,還將實現(xiàn)移動因特網(wǎng)和萬維網(wǎng)瀏覽。1981年誕生的第一個具有國際漫游功能的模擬系統(tǒng)NMT的使用頻段為450MHz,1986年NMT變遷到900MHz頻段。s wide band, networking39。s yearly rate will reach as high as 300%, obviously the user will turn on Internet39。s use frequency band is also 900 MHz. In the second generation of network, the GSM system39。s intellectualized development, the motion intelligent network lives from this. About the motion intelligent network39。s dividing line bees fuzzy, the people need not to divide, the place visit very important information. Will occur will bee the actuation wireless data traffic development on the user body39。未來的網(wǎng)絡(luò)將向?qū)拵Щ⒅悄芑?、個人化方向發(fā)展,形成統(tǒng)一的綜合寬帶通信網(wǎng),并逐步演進為由核。五、更高的頻段 移動通信需求的不斷增長以及新技術(shù)在移動通信中
