摘要:
根据蓝牙“三合一电话”应用模型要求,通过内核配置、基础库和工具集的移植以及内核烧写等步骤,将蓝牙BlueZ协议栈移植到嵌入式ARM平台,编程实现了TCS Binary协议,研制完成了一种基于嵌入式蓝牙协议栈BlueZ的语音无线接入系统,包括嵌入式蓝牙语音网关和蓝牙语音终端.采用研制的蓝牙语音接入系统可以较好地将蜂窝网的话务量分流至PSTN中,利用话务模型对用户密集和蜂窝资源紧张的通信环境进行了仿真研究,结果表明蜂窝网呼损率显著下降,提高了PSTN的利用率,增加了由蜂窝网和PSTN组成的语音通信网的系统容量.
Abstract:
According to the Bluetooth “three in one phone” application profile, by kernel configuration, transplant of basic library and tools, and kernel programming, the Bluetooth BlueZ protocol stack is transplanted upon embedded advanced RISC(reduced instruction set computer)machines platform and the telephony control specification(TCS)binary protocol is programmed. An audio wireless access system, including Bluetooth audio embedded gateway and Bluetooth audio terminal, based on Linux Bluetooth protocol BlueZ is developed. With the developed system, the traffic is diffracted from the cellular phone network to public switched telephone network(PSTN). Based on the traffic model, the simulation results indicate that the calling blocking probability in cellular phone network is observably decreased, the utilization percent of PSTN is increased and the system capacity of audio communication network combined with cellular phone network and PSTN is also increased.
