： 在 Inter 飛速發(fā)展的今天 , 互聯(lián)網(wǎng)已經(jīng)成為了網(wǎng)上生活的基本工具 , 它不僅用于瀏覽網(wǎng)上的信息 , 還成為信息發(fā)布、商務(wù)活動(dòng)的媒介。同時(shí) , 隨著有線(xiàn)網(wǎng)絡(luò)的不斷發(fā)展 , 移動(dòng)無(wú)線(xiàn)網(wǎng)絡(luò)也在飛速發(fā)展著 , 從最早的模擬通信技術(shù) , 到現(xiàn)在的數(shù)字通信技術(shù) , 第二代、第三代網(wǎng)絡(luò) , 移動(dòng)無(wú)線(xiàn)網(wǎng)絡(luò)的傳輸速度越來(lái)越快 , 以語(yǔ)音傳輸為主的傳輸也在逐漸向數(shù)據(jù)傳輸發(fā) 展。如果移動(dòng)無(wú)線(xiàn)網(wǎng)絡(luò)能夠與 Inter 系統(tǒng)相連 , 則可以方便、低廉 地將信息傳輸?shù)绞澜缟先魏蔚胤?, 真正做到隨時(shí)隨地 , 在任何設(shè)備上進(jìn)行存取信息。其應(yīng)用前景十分的廣闊。因此 , 如何將有線(xiàn) Inter 系統(tǒng)與無(wú)線(xiàn)系統(tǒng)相結(jié)合 , 成為一個(gè)熱門(mén)課題。目前 , 無(wú)線(xiàn)數(shù)據(jù)服務(wù)模式也是多種多樣 , 如 SMS, EMS, WAP, MMS,JAVA,BREW 等 , 基于這些模式上的信息服務(wù)也得到了爆炸性的發(fā)展。而互聯(lián)網(wǎng)提供了多種多樣的服務(wù) , 其中電子郵件服務(wù)以方便、快捷的特征成為人們對(duì)內(nèi)、對(duì)外交流的一個(gè)重要途徑。所以很有必要通過(guò)移動(dòng)無(wú)線(xiàn)網(wǎng)絡(luò)來(lái)收取有線(xiàn)互聯(lián)網(wǎng)上的郵件 , 使郵件成為各種信息傳輸?shù)?綜合平臺(tái)。本文正是在這樣的背景下進(jìn)行了基于 Java ME 的無(wú)線(xiàn)郵件系統(tǒng)的研究。 關(guān)鍵詞 ： Inter； 通信技術(shù) ； 電子郵件 ； 服務(wù) Based on mobile Email system design and openness Abstract : In the Inter rapid development today, the Inter has bee the basic tools online life, it not only used for browsing online information, also be information release, business activities medium. At the same time, along with the continuous development of cable work, the mobile wireless work is growing rapidly, from the earliest analog munications technology, to today39。s digital munication technology, the second and third generation mobile work, wireless work transmission faster, mainly in speech transmission transmission to the data transmission in gradually hair exhibition. If mobile wireless work that connected with Inter system may be convenient, inexpensive information transmission to be anywhere in the world, acplish truly anytime, anywhere, at any equipment for access to information. Its application prospect br
