多PSTN蓝牙网关系统的研究及实现
|
摘要
近年来随着移动通信技术迅速发展,它已有逐渐取代固定电话网的趋势。但是移动通信仍然存在着信号不稳定,话费较贵的缺点。因此如何融合移动通信和固定电话网成为研究的热点。PSTN蓝牙网关系统正是一种融合移动通信和固定电话网的技术,为如何充分利用固定电话网资源提出了新的发展方向。
首先介绍了蓝牙技术和PSTN蓝牙网关的概念及研究现状,分析了现有PSTN蓝牙网关存在的缺陷,并详细介绍了蓝牙协议栈。然后分析了系统的功能要求,给出了系统的硬件结构和软件框架,设计了蓝牙功能模块与电话电路模块之间的交互命令,并详细分析了系统的工作过程。接着对本文的两个关键技术――无绳电话剖面以及多PSTN蓝牙网关动态选择进行了深入研究。在讨论了无绳电话剖面的基础上,设计了无绳电话剖面软件的管理模块和应用模块。分析了现有PSTN蓝牙网关存在的问题后,提出了多PSTN蓝牙网关动态选择算法,详细分析了该算法的工作过程以及算法设计,并进行了性能分析。最后给出了系统硬件和软件的具体实现。
In recent years, with the rapid development of mobile communication, it has the trend which is the gradual replacement of fixed telephone network. However, the unstable signal and more expensive charges still exist. How to converge fixed telephone network and mobile communication becomes the hotspot of research. PSTN Bluetooth Gateway is a fixed-mobile convergence technique, which provides a new direction of development for how to make the best of fixed telephone network.
Firstly, bluetooth technique, bluetooth protocol stack and PSTN bluetooth Gateway are introduced and the problem of the exiting PSTN bluetooth technique is analyzed in this paper. After the system requirements is discussed, the structure of hardware and the framework of software is presented, the interactive order between bluetooth module and telephony module is designed, and the procession of system is analyzed in detail. The two key techniques—cordless telephony profile and multi-PSTN bluetooth gateway dynamic selection are studied in depth. On the basis of the discussion of cordless telephony profile, the software which includes manager module and application module is designed. After the problem of existing PSTN Bluetooth gateway, multi-PSTN Bluetooth gateway dynamic selection is prensted, the procession and the design is discussed in detailed and the performance is analyzed. The implementation of hardware and software is presented at last.
