摘要:

针对手机微波辐射对人体造成的伤害问题以及移动通信网络、固话网络间不兼容的问题,设计了一种使用蓝牙技术的PSTN语音网关。分析了PSTN和移动通信网络融合的必要性,阐述了系统的功能,并给出了完整的硬件结构和软件架构。通过实际使用测试,手机和网关在10 m距离内,音质清晰、通话质量良好。

关键词: 蓝牙技术, PSTN, 网关

Abstract:

A PSTN Audio Gateway using Bluetooth technology has been proposed to handle the problems of mobile phone microwave radiation damage on human body and the incompatibility between mobile communication network and PSTN.Firstly an analysis on the necessity of the integration between PSTN and mobile communication network is made.Then we elaborate the function of the system.Finally the complete hardware architecture and software architecture is given.Practical tests show that the voice quality is good when the distance between the mobile phone and the gateway is within 10 m.

Key words: bluetooth technology;PSTN;gateway
