教育在本质上就是对知识和经验的共享和交流，而网络的本质就是一种信息共享服务，它在很大程度上改变了时间和空对间人们之间信息交流的约束，可以让人们以极低的代价、极高的效率共享信息和知识。所以对于教育这种几乎可以纯数字化的行业而言，应该是最能发挥移动网络优势的行业之一。在国家大力发展教育信息化的大背景下，学校推进信息化来加强办学水平、提高师生的信息化素养、促进家长与学校形成合力共同开展教育是目前极为迫切的任务。Education is essentially the sharing and exchange of knowledge and experience, and the essence of the Internet is an information sharing service, which largely changes the constraints of time and space on information exchange between people, allowing people to Sharing information and knowledge at extremely low cost and extremely high efficiency. Therefore, for an industry that can be almost purely digitized, education should be one of the industries that can best take advantage of the mobile network. Under the background of the country's vigorous development of educational informatization, it is an extremely urgent task for schools to promote informatization to strengthen the level of school-running, improve the informatization literacy of teachers and students, and promote the joint efforts of parents and schools to jointly carry out education.

结合教育行业特点、信息化趋势及用户需求，目前行业发展的方向是通过建立一个综合性的网络教育互动信息平台将各种优质的教育资源和沟通手段有机的结合起来，通过信息平台及教育集群网在一定程度上捆绑教师群体，最终通过全面推广进而培养稳固家长群体，逐步培养行业对移动网络及品牌的依赖性，从而形成一套完整的带有信息化特色的服务体系和标准体系。Combining the characteristics of the education industry, information trends and user needs, the current direction of industry development is to organically combine various high-quality educational resources and communication means through the establishment of a comprehensive online education interactive information platform. The Internet binds the teacher group to a certain extent, and finally cultivates a stable parent group through comprehensive promotion, and gradually cultivates the industry's dependence on mobile networks and brands, thus forming a complete service system and standard system with informatization characteristics.

然而，多年的办学历程，学校方面已经保存了大量的教学资源，上传这些数据已经成了一个问题；而且频率的数据上传与下载也将占用的珍贵的带宽资源，这也是目前学校必须解决的问题。However, over the years of running a school, the school has saved a large number of teaching resources, and uploading these data has become a problem; and the frequency of data uploading and downloading will also occupy precious bandwidth resources, which is also a problem that the school must solve at present .
