Dcom Server Design Of The Bluetooth Protocol Stack With A Pc (headphones) Wireless Voice Communication

Mobile communication technology has been gained flourish development last several tens year,it has been developed from the first generation simulation communication system manifested by audio transferring to the second generation GSM digital communication system and GPRS data t system manifested by data and audio transferring simultaneously and to the third generation mobile communication system. But these communication system basicly belong to global wireless communication technology, wireless communication application don't restrict to these global field, however, some local region such as office, home, all kinds of information devices also require to inter-link each other by wireless instead of wire. So based on this fact, my project is put forward;nowadays,a large number of well-rounded control software and communication software is based on RS-232, TCP/IP, IrDA and so on mature communication technology, if we don't mak full use of these software and to newly develop new software based on bluetooth fully will result in wasting huge resource existed. ;COM technology have stronger reuse , independen location, and inter-flatform and so on peculiarity , and the N layer structure of DCOM server can independedly encapsulate and run bluetooth logical process, moreover , DCOM will provide bluetooth services to high layer but maskingthe bottom bluetooth communication process;As a new communication technology , the protocol model and realization of bluetooth technology both in a low development stage , so this paper make amount of work about it to deeply analyse bluetooth core protocol. Base on these work, i put forward a new point to construct a new type bluetooth protocol stack DCOM sever to support several instances, encapsulate bluetooth core protocol , communication logical flow. On this DCOM sever , i realize a PC wireless audiorealize a PC wireless audiocommunication experiment system by means of bluetooth headset operationprofile and widely used serial communication technology.This paper emphasis on several work described as follows:1. Deeply research the work theory of bluetooth core protocol .2. Using COM technology to programme core protocol object component.3. Research DCOM remote communication theory and realize the inter communication between DCOM sever and client.4. Research wireless serial communication tehcnolgoy SPCP and DirectX audiodriver technology.5. Using SDL and MSC technology to standardize and design a reliable communication system.6. Design a PC wireless audio communication system based on bluetooth headset to realize wireless audio communication in piconet .My experiment has proved that bluetooth protocol stack DCOM server is reliable, extendable and have good application. In addition ,if the bluetooth DCOM sever has been rightly configured ,now existed RS-232 communication software can be well running and transfer data without serial wire ,obvious, using bluetooth DCOM server can extend the life period of existed software and hardware resource .
