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

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

system, the constitution of module can increase
with the demand of learning content and function.
In the module of the system, the knowledge module
is the field of knowledge which can be illustrated by
a hyper topology structure of knowledge; as in Fig.3, resource module supplements the curriculum
content with providing course related material, resources, questions and so on; teaching module is
divided into teacher module and student module, it’s the assembly of the communication of the
teachers and the students with providing the evaluation results to learning effect of the students and
give appropriate guidance, this module can modify other module according to evaluation results and
guidance effects with a certain
intelligence as in Fig.4.
4.2.Process of Mobile Learning
Network System Development
The development of mobile
learning network system should be
started with the guidance to carry on
the instructional design by teaching
theory, including the creation of
