摘要: 讨论了基于Nucleus Plus嵌入式操作系统在第3代移动通信网络(WCDMA)手机中实现GPS定位的关键技术。根据Nucleus Plus操作系统的特点,使用队列和Timer机制管理所有的测位请求,避免了资源的竞争,实时地满足了每一个测位请求。结合3GPP协议的X1消息和网络数据格式解决了服务器与客户端的通信以及网络数据和GPS硬件数据格式的不统一问题,同时增加了指南针功能模块,从而实现了第3代手机GPS定位功能和汽车导航功能。

Abstract: This paper discusses the key techniques of realizing GPS orientation in 3G mobile phone based on Nucleus Plus embedded operation system. It manages all requests by queue and timer mechanism based on characteristic of Nucleus Plus OS, avoiding competition of resources and satisfying every request real-timely. It resolves communication of server and client and disunion problem between network data and GPS hardware data format by combining X1 message of 3GPP protocol, and realizes GPS orientation and car navigation of 3G mobile phone by adding compass module.

Key words: GPS, orientation, third generation partnership project (3GPP), embedded system, car navigation
