摘要
当今时代是个信息时代,也是一个手机的时代,现代生活对手机的依赖相当严重。J2ME是近年来随着各种移动通信设备的发展而诞生的一项新的开发技术,因其“一次编写,到处运行”的Java特性而提高开发的效率。随着手机的普及、互联网的日益更新和发展、Java功能在移动设备上的实现,越来越多基于手机平台的应用更是在飞速发展,对丰富人们的生活内容起着不可忽视的作用。
发送和接收文本信息是手机传统的通信功能,也是人们日常生活中不可缺少的一种通信功能,运用无线接口函数WMA设计实现此功能;同时针对互联网络的更新和3G网络的发展,又提出了手机的网络通信——即时聊天系统的开发与应用,在设计和实现此功能时,采用了基于TCP的Socket传输协议,并运用了MIDP的网络通信功能。
本论文着眼于J2ME技术的应用,还选择了基于TCP/IP协议的网络编程技术。论文首先介绍了Eclipse集成开发环境、J2ME的体系结构、配置、简表等基础知识;其次,分析了实现手机通信功能的相关基础技术及理论,即无线接口函数WMA、MIDP的网络通信功能等;最后,运用JAVA语言编程,并在SUN公司提供的模拟器上模拟手机发送和接收文本信息及手机与PC机、手机与手机的网络通信的功能。

Abstract
The present era is the information age, is also an era of cell phones, modern life's dependence on the phone quite in recent years a variety of munications equipment with the development of the birth of a new technology, Its "write once, run anywhere" nature of Java to increase the efficiency of development. With the popularity of mobile phones, the to update and develop the growing, Java function in the realization of mobile devices, More and more applications based on mobile platform is in the rapid development and plays a role in rich content of people's lives, that can not be ignored.
Send and receive text messages is the munication functions of mobile phones and is also an indispensable feature of munication to daily life, The use of wireless interface function WMA designed to achieve this function; At the same time, the update for the and works, put forward a cell work -- real-time chat system development plement, in the design and implementation of this feature using the Socket based transport protocol TCP, and use of munication function MIDP.
This paper focuses on the application of J2ME technology, have also chosen based on the TCP / work protocol programming. Paper introduces the Eclipse int
