基于OBEX的文件传输在手机平台上的应用

File transfer based on OBEX and its application in mobile phone platform

微型处理器的运算速度和存储容量的不断提升,使得手机在作为通讯工具的同时,更向多媒体方向发展。文件传输作为多媒体应用的基础,在手机平台上得到了广泛的应用。通过对对象交换(objectexchange,OBEX)协议的深入研究,提出了实现此协议的框架,以及在此框架上对文件传输功能的实现,其中对于OBEX协议没有提及的文件夹传输给出了解决方案。基于OBEX协议的文件传输以其简捷高效的特点将在手机平台上得到了广泛的应用。

With higher processing speed and larger performance memory, mobile phone has not only communication function, but multi-function capabilities. As the base of multimedia, file transfer applications are used in many phone development platforms. After application research, a framework about OBEX （object exchange） is described and an approach is presented for file transfer based on the framework. In particular an efficient and compact arithmetic is also described for transferring folder which dose not referred in OBEX profile. The high efficiency feature will make it possible for file transfer to be wildly used in mobile phone platform.
