The Development of Mobile Internet Browser Based on 3G Netwo

　　abstract：the communication technology and internet technology are inseparable all the the advent of 3g,which has lead to a revolution in the internet,mobile internet came into being. this paper discusses of paper the mobile browser in the current mobile internet and mobile internet in the future the important role played .according to the views in this article, our team designed and developed a new mobile browser called “duoguo mobile browser”.

　　1. introduction

　　2009 is the first year of china’s telecommunications industry of 3g era, which is also the first year of china's mobile internet is a integration of mobile network and internet. mobile internet business shows a feature that mobile communications business and internet business integration internet business applications are also following the traditional path of the development of internet business .from the portal website,instant messaging, the searching service extend to the social services, etc.i mobile internet business is increasingly clear, while of the internet and traditional profit model is the mobile internet can be copied.

　　mobile internet is not only the internet can be its business, the mobile internet business is broadly divided into three categories: first, a copy of the fixed , the mobile communications business as the internet, and the third is the innovative mobile internet business. as the mobile its industrial chain will become very complicated, including terminal device manufacturers, telecom operators, service providers, system developers and so ore, the mobile internet business model has become more complex, more diversified.

　　however, if you want to achieve the above and experience the mobile internet business, there must be a good access point and good way to achievethe .the best direct way that the mobile phone connects to the internet is the mobile browser. mobile phone’s browser as a important interface of mobile phone which connects to internet is getting more and more internet in the mobile is particularly valuable,the information is difficult to read too much, and there is too little information on the lack of ed with computer browser,mobile broswer works in the environment of low cpu processing power, storage space for small, small display screen of the mobile embedded . this doomed the best mobile phone's browser must have good experience.

　　based on this background, we designed and developed “duoguo mobile browser”.

　　2. today’s mobile browser

　　this mobile browser was developed by qt. qt is a complete developing framework which applied c++,it includes a class library for cross-platform tools, and internationalized, qt’s api on all supported platforms are the same,

　　qt tools on these platforms use the same qt application development and deployment are platform-independent

　　qt supports the following platforms(shows in figure1.1):

fig.1.1

　　“duoguo mobile browser” can be applied to the vast majority of smart phone platforms

　　2.1 the issues of mobile phone browser by now

　　user’s experience is a choke point of the development constraints of mobile low memory, low cpu performance of the mobile terminal on a good user experience, will be a very important aspect of attracting users.

　　2.2 what we have done to solve the problem

　　this browser used source-open web pagerendering engine ”webkit”.because of its clear source structure and fast page rendering speed ,apply to the use of mobile terminal. and we cut down its core source and transplant,so that it can more applicable to mobile phone operating system.

　　the browser will bring a browsing close to the computer browser. we give users the basic functions of the browser , such as home navigation, bookmark,history,and so it can not delete the page and any content, source of the page will be analyticed can enjoy the internet experience like they do on the computer.

　　at present,the mobile phone's browser renders the pages by the method of indent and compress. the effect of the user experience far from ideal. and the web content and functionality has been severely cut, can not meet the needs of users.

　　fig 2.1 illustrates the ie core browser which is widely used by windows mobile platform currently. website visit results are quite different from the original page, the effect of the user experience far from ideal.

　　fig 2.2 is of webkit core ”duoguo mobile browser”.website visit results are all the same as the original page,users can view the entire page by the way of drag-and-drop, gives the user's desktop-like mobile internet experience and easy to control.

　　3. tomorrow’s mobile browser

　　3.1 the entrance of wireless sensor networks

　　with the development of wireless sensor networks and rfid, mobile terminals will be equipped with rfid functions of wireless identification and sensing will be added into mobile browser at that time, it can not only browse the information in mobile internet ,but also can browse the real-time information generated by wireless browser will be the key nodes which connect the wan and lan.

　　the popularity of 3g promotes the development of mobile internet, the traditional mobile internet business is built on the long-distance wide area networks, but mobile wireless lan-based business is still blank. so, we hope that the mobile phone's browser to become the entrance of wireless lan

　　3.2 the entrance of cloud computing

　　with the wireless communications network transmission rate rising, cloud computing gradually into the outlook of people. cloud computing is the development of parallel computing, distributed computing and grid computing, or is the business readization of computer science.

　　cloud computing is mixed and jumped the result of virtualization,utilitycomputing,laas,paas,saas.

　　cloud operating system could be divided into three types as there is the browser or not which illustrates in fig.3.1

　　it is clearly the hight os is much more fittable for the mobile terminals.

　　at present, the functions of mobile termchal are complicected,softwares are varied but their functions are is a serious challenge for the performance of low memory and low cpu,and also is a choke point for the development of mobile terminal. also constrained the performance of mobile terminal development, a the development of high-speed mobile communication network, many functions could be dealt with the method of colud computing in the network-side.

　　the best advantage of cloud computing is the “ultra-large-scale” for the users of mobile terminal ,the capacity of date processing is limited for mobile phones by the method of cloud computing,we can put our computings into the “cloud”."cloud" to give the users an unprecedented computing power, the data which could not be dealt data and the task can be completed with using a mobile phone will be ended in the era of cloud computing.

　　cloud computing also high reliability, high security, general-purpose, high scalability, on-demand services, the advantages of computing is a great impetus for the future development of mobile internet. the quality of terminal browser is directly related to the developing prospects of cloud computing.

　　3.3 what “duoguo mobile browser” will do in the future

　　in the future,we are going to put the proceedings in the browser search function mobile lan module, bluetooth module for mobile phones through the development and the development of rfid chips to achieve the mutual perception between the terminal and mutual recognition, to form the mobile wireless lan. figure 3.2 below:

fig3.2

　　we hope that will be transplanted to the browser in a wide variety of embedded devices, while providing a variety of client in the network storage and computing the corresponding services. users can browser through a wide variety of computing and the resources available.

　　mobile end-users access the network through a browser, to enjoy the services provided by cloud computing, small-screen mobile phone's browser to the user whether the operation of an excellent experience and visual experience is directly related to the service user loyalty. "software as a service" is a concept advocated by cloud computing, cloud computing for the mobile internet has added an infinite number of possible. when the clouds come with all the services, the browser will gradually replace the operating system, "the browser is the future of the operating system"

　　4. conclusion

　　3g era of chinese telecommunications is coming,there will be a explosive growth of mobile internet in china,the quality of mobile internet will be one of the key points in the development of mobile internet.
