摘要

 随着通信技术的高速发展，消费类电器和嵌入式设备的技术开发的瓶颈问题日益突出。一方面，商品制造商的研发能力无法满足用户不断增加的功能需要，另一方面广大的软件开发制造商却又无法参与到其中来。这样导致应用程序的开发变得越来越困难，极大的制约了这类设备新应用的推广和普及，而且现有的解决方案不够智能，使无线通信应用受到了很大的限制。J2ME(Java 2 Micro Edition)的出现对以上问题提供了完美的解决方案。本文对移动设备所涉及的大量技术问题进行了深入的研究和说明，使用MIDP（Mobile Information Device Profile）赋予的强大开发工具包并结合实例，重点阐述了相关技术的实现。
 文章首先对短消息服务系统进行介绍，分别描述了文本消息、多媒体消息和小区广播，并介绍各自特点。然后介绍了J2ME开发平台NetBeans的主要功能选项，最后介绍了系统功能的实现。

ABSTRACT
 With the rapid development of communication technology, the bottleneck of consumer appliances and embedded devices technology development have become increasingly prominent. On the one hand, manufacturers of goods R & D capability can not meet the needs of the ever-increasing functionality, the software development on the other hand, the majority of manufacturers in which they can not participate in the past. As a result, application development is becoming increasingly difficult, greatly restricted the application of such equipment to promote the new and universal, and the existing lack of intelligent solutions to enable the application of wireless communications has been greatly hindered. The emergence of J2ME (Java 2 Micro Edition) solve  above provides  perfectly. In this paper, research and shows mobile devices involved in a large number of technical issues in-depth, the use of MIDP (Mobile Information Device Profile) to give a powerful development kit in combination with examples, focused on the realization of related technologies.
 This article introduce short message service system first , described the text messages, multimedia messages and cell broadcast, and describes their respective characteristics. Then introduced J2ME development and the main functions of NetBeans platform options, and finally introduces the realization of system functions
