摘  要

现代社会对无线移动终端功能要求很明确：通信速度快、功能齐全。传统的单一的通讯功能已经不能满足人们的需求。本课题的设计就是基于android智能平台，实现了传统的通信功能、个人考勤信息管理和网络社交功能。也应用了3G手机的定位功能，3G网络的高速率特性保证了GPS定位功能的精确性和实时性，利用此功能开发的基于地理位置的通信考勤平台也会更加实用。支持高速数据传输的3G通信技术，可以双向下载传递资料、图画、影像，其代表特征是提供高速数据业务，极大的满足了人们的通信需要。通过对3G手机常用的android系统的研究，测试了这种平台的大部分功能，android系统的开放性特点、良好的第三方程序开发环境和高效的可扩展性功能也方便了在android平台上才各种应用的开发。Android是一种新的系统，不需要考虑对旧系统的兼容，因为对旧系统的支持会让系统速度变得非常缓慢， android从一开始就专门为最快的硬件而设计，所以它的运行速度非常快。

ABSTRACT

In modern society, the functional requirements of wireless mobile terminal are very clear: fast communication speed, full function. The traditional single communication function already can not satisfy peoples needs. This topic design is based on the intelligent platform of android which can achieve the functions such as  the traditional communication,the personal information management and social networking function.And it also can help the 3G mobile phones to apply for positioning,the high-speed characteristics of the 3G network ensure the accuracy and real-time of GPS positioning, therefore, the location-based attendance communication platform which develops by taking advantage of this feature will be more practical. And the 3G communication technology which supports the high-speed data transmission —— you can use it to download the two-way transmission of information, pictures, images, characterizes by its representatives to provide high-speed data services and to meet peoples communication needs greatly. The 3G mobile phone is a mobile terminal which based on this technology, through the android system research   commonly used by 3G phones, experts tested most function of this platform, its remarkable features including openness, a good third-party program development environment and efficient scalable sexual function is also convenient to develop a variety of application in the android platform. Android system is a new system that it does not need to consider the compatibility of the old system because the support of the old system will lead the speed of this system becoming very slow .The android system is specifically designed for the fastest hardware from the beginning, so its running very fast.

Keywords: GPS positioning, android，message systems, mobile terminals, 3G networks
