This paper sets up a mobile learning service system through the </p><p>construction of teaching cloud platform and cloud resources, cloud resource sharing, application and </p><p>service of cloud resource, system and mechanism construction. The mobile learning network system </p><p>is established by building models of it, which realizes mobile learning, collaborative learning and the </p><p>situated learning anytime anywhere with freedom, individuality and diversification. </p><p>1.Introduction </p><p>With the development of Wireless Communication Technology and Mobile Computing </p><p>Technology, mobile learning has gained more and more popularity among people as the branch of </p><p>digital learning, which becomes a research focus of educational technology and related fields. As a </p><p>new form of learning, mobile learning showed great application potential in school education and </p><p>training field. How to make full use of development achievements of new technology to build a more </p><p>efficient and practical mobile learning system and dig out the potential application of mobile learning </p><p>is worthy of further study. Cloud Computing' s coming provides a new way of mobile learning system </p><p>development that meets the users needs. Distributed computing and Resource sharing in large-scale </p><p>heterogeneous system are the key technical problems to which cloud computing technology provides </p><p>an ideal technical solution to realize mobile learning system. To build mobile learning network </p><p>system based on cloud computing can satisfy the demand of user to access abundant, real-time and </p><p>accurate learning contents, to provide immediate learning support in the process of learning, and to </p><p>support collaborative learning and the situated learning. </p><p>2. Cloud Computings Support to Mobile Learning </p><p>Cloud computing is a super computing mode based on Internet., which concentrated large </p><p>amount of information and processor resources that is stored in personal computer, mobile phones </p><p>and other devices together, and collaborative work. It distributes computing missions on large amount </p><p>of resources consisting of computer, so that all applications can access computing, storage space and </p><p>a variety of software service according to the needs. With the development and popularization of </p><p>cloud computing technology, information of educational institutions, teachers and students will </p><p>gradually move to the "cloud". The main features of cloud computings support to mobile learning can </p><p>be described as the following four aspects. </p><p>2.1.Make up the Insufficiency of Mobile Learning Model </p><p>There are two main models of mobile learning at present, respectively Short Message Service </p><p>(SMS) based and browser based WAP education web site. The two models have their shortcomings, </p><p>SMS mode data usually has a certain delay, so teaching and learning do not interact in real time. In </p><p>addition, the amount of data transmission of this model is quite limited and it generally only transmits </p><p>text information, which makes it difficult to meet the needs of the users for multimedia resources. </p><p>Applied Mechanics and Materials Vols. 631-632 (2014) pp 1451-1456Online available since 2014/Sep/12 at (2014) Trans Tech Publications, Switzerlanddoi:10.4028/</p><p>All rights reserved.

Besides, this model based on </p><p>WAP browser protocol with low transmission rate. The emergence of cloud computing, makes up the </p><p>above two models of mobile learning. Plenty of educational resources stored in the cloud server, </p><p>large-scale mobile learning could be realized without the establishment of special education site. </p><p>Cloud computing integrates multiparty computer and new technology of Internet, which is a </p><p>breakthrough over single WAP protocol. Under the background of cloud computing, the students only </p><p>need to use the mobile device to access the "cloud" server through the browser and choose the </p><p>learning content to learn by real-time interaction. </p><p>2.2.Integration of Abundant Learning Resources </p><p>The fundamental purpose of the integration of education and cloud computing is to fuse and </p><p>store educational information and to share through network service, for which integrate and use the </p><p>educational resources to the maximum extent. Worldwide educational resources assemble in the </p><p>cloud storage server, its the teachers who classify, manage and formulate relevant access rules. At </p><p>the same time, the resource database is improved by students and teachers who supply and modify </p><p>existing learning content under certain rules in the process of learning. </p><p>2.3.Support the Establishment of Pluralistic Autonomous Virtual Learning Community </p><p>Under the cloud computing, all resources are integrated in the "cloud", which could be used to create </p><p>free virtual community and virtual learning environment and learn cooperatively with other students </p><p>who share the same learning goals by students. It is because they create the virtual community on their </p><p>own that they can bring out their best and show their personalities as well as communicate free. </p><p>Furthermore, since it is based on the network, the composition of the students break through the limits </p><p>from radiation scope of the existing virtual community that people from different countries and </p><p>cultural backgrounds could enter the community studying and discussing together, which provides </p><p>reference experience and complement for each other, thereby realizing multicultural and knowledge </p><p>exchanges. </p><p>2.4.Reduce the Requirements for Mobile Learning Devices </p><p>Problems in the mobile learning device are the main factors that restrict the development and </p><p>popularization of mobile learning. The main problems are, low data processing ability, limited </p><p>built-in software and limited transmission of multimedia resources. The emergence of cloud </p><p>computing technology provides a feasible solution for these problems. Under the cloud computing, all </p><p>of the data will store and process in the computer group of the cloud. It can perform some data </p><p>processing task which many personal computer is unable to do due to its powerful computation </p><p>ability. With all of the data processing on the cloud, the students can only use the browser to do </p><p>some common action similar to personal computers as long as the browser is able to run on the mobile </p><p>device. </p><p>3.Construction of Mobile Learning Service </p><p>System of Cloud Computing </p><p>The author sets up a mobile learning service </p><p>system according to actual demand with better </p><p>expansibility.
