【摘要】 采用蓝牙通信技术的车载免提系统是汽车电子行业在通信领域的新兴产品。随着越来越多的汽车厂商意识到附加的个人通信设备为汽车带来的市场竞争力,车载免提系统的技术发展获得前所未有的巨大推动力。当下市场对车载免提系统的功能要求日趋多元化,其中,与手机实时同步电话簿的功能被视为一个提高竞争力的产品增值点,该功能的开发成为免提系统发展技术的迫切需求。本文重点研究了一种可与现有的车载免提系统无缝结合,应用蓝牙技术实现将电话簿信息从手机设备同步到车载设备端的通信方案。该方案充分考虑了新的通信系统与原有系统的无缝接合特性和交互的智能化要求。由于已有的蓝牙通信安全技术不能够完全满足同步通信系统的安全需求,本文在原有系统的基础上扩充了一套应用于服务级的安全管理机制。本文选取基于Symbian Series 60操作平台的手机作为同步系统客户端的研发设备。从理论分析和设备实测两个角度探讨了HFP、OPP和SyncML三种蓝牙框架应用于电话簿同步方案的可行性,最终选取OPP框架作为同步通信的基本模式。本文在对系统的安全需求与威胁作了全面的分析之后,设计了一种结合链路级安全与服务级安全,以授权和鉴别为核心思想的安全机制。此外,本文研究了客户端同步软件的设计思想和在Symbian平台上的实现方法,详细阐述了自动连接、电话簿数据创建与更新和优先处理呼叫业务三种关键技术;最后,在完整的车载免提应用环境中对同步系统进行真实的测试,结果表明,同步系统的运作在安全和智能性方面都达到了预期的设计目标。更多还原

【Abstract】 Bluetooth HandFree car kit is the latest communication product in telematic industry. Since more and more car manufactory realize personal communication accessory can add tremendous value to cars, the development of Bluetooth HandFree car kit related technology has been highly promoted. Customers require HandFres car kit to combine multiple functions. The ability to synchronize phonebook from cell phone to car kit is the most urgent demand presently.The thesis mainly focuses on a Bluetooth technology based phonebook synchronization method which can seamless fit in the present HandFree car kit. In this method, we put much emphasis on the seamless combination of the Handfree application and synchronization. as well as the intelligent interaction between car kit and cell phones. Since the present BlueTooth security mechanism which works on the link level is not enough to meet the system security demands, a whole set of security mechanism to cover the application needs is put forward.The Symbian Series 60 cell phone is selected to be the client device in this research. In the first part of this thesis, three initial frameworks are proposed respectively based on a study in HFP, OPP and SyncML. They are also tested with Nokia 6681 to verify the profile compatibility. OPP is finally chosen according to the test results. The second part is an overall analysis in system security, including both the demands and threats. Further more, a system security mechanism is designed to meet the needs. This mechanism perform authorization for service-level security and authentication for link-level security as well. After that, the thesis explains how to implement the client software on a Symbian platform. In this part, three key techniques are illustrated in more detail, including automatic connection, database management and upload interruption upon high priority event, like calls. In the last part, a system test is preformed to within an integrated environment. The test results show a good performance in system intelligence and security.更多还原
