ABSTRACT
Communication plays an important role in today's time. Globalization has led the need for crossover communication. Therefore multimedia system plays an important role in the overall communication between regions. Multimedia system provides seamless provision of multimedia services to its user. The conferencing system ensures that voice, video and other media forms are streamed efficiently to various individuals ensuring smooth real time communication. Currently, this multimedia system does not support this facility in all the mobile operating system. Thus we have proposed an Android based multimedia conference terminal system on 3g mobile phones. In this way 3G users will be allowed to communicate with individuals across regions.
INTRODUCTION
Cross region communication has become increasingly important due to globalization and trade. Multimedia conference system is put to use instead of traditional conference to enhance communication efficiency, save staff‟s time and reduce conference cost. The maturity of Internet application service and the wide spreading of broadband access technology help to accelerate the development of multimedia conference system. Due to the development in networks that is the emergence of 3G networks and introduction to new smart phones has led to the popularity of the conference system on mobile phones. 3G network provides high-speed data transmission capability. The new age smart phones are intelligent and sophisticated in features and hence support enormous applications. Due to the portability feature and personalization of trends in mobile terminals, applications like multimedia conference can be easily mounted on these terminals. At present, the mainstream mobile phone operating systems include Symbian, Windows Mobile, iOS and Android. The Android operating system is the newest among all these. It has 38.1% market share according to a survey in May 2011. This percentage has been increasing regularly with the rise of smart phone users. Under this background, we have designed and proposed a Android based multimedia conference terminal system on 3G mobile phone to facilitate 3G users to attend multimedia conference.

Architecture of Multimedia Conference System
Figure 1 shows the topology architecture of the multimedia conference system. Here the typical kinds of users who can enjoy multimedia conference services are given. They are the telephone users, 3G cell phone users or the computer users. The network used for each of the user depends on the terminal type. If the terminal is a telephone then the network used is a switching system that is, PSTN. If the terminal is the computer then the network is the internet service and the networking device used is a router. For 3G mobile phones the network used is 3G and it has base stations which connect to the MSC. From the network, the communications through the gateway which is a network device mapping to all the OSI layers takes place. From there the conference system is managed and controlled by the Conference control server and media server. These two servers help in establishing a conference as well as managing all the details of conference call.
EVALUATION
We have installed the multimedia conference mobile terminal application on Android OS phone Samsung Galaxy note and done the experiment of actively attending conference to evaluate the functions of the application. The application snapshot is shown in fig 5. The video view will show the video captured by front camera of the user to who call was made. Also other users who are not active but are in the conference can be seen. That is called as the switch terminal. Also if someone wishes to add a person on conference then the number needs to be entered in order to make the call. The person can also end the conference in a midst of an ongoing conference.
Figure 6 shows the main view of the multimedia conference system. The user can view conference which shows the details of the conference being held. Attend Conference helps the user to become a part of the ongoing conference.
CONCLUSION
The networking field is expanding on a great scale incorporating many new technologies and applications. This network with immense advancements has provided many entry points for smooth communication. Voice, video and document sharing has become a mundane task due to the emergence of advanced technology. Multimedia conference system is becoming increasingly popular among enterprises and government departments by right of its efficiency and cost-saving features. In this paper, we have designed and implemented a Android based multimedia conference mobile terminal application, with which 3G mobile phone users can attend multimedia conference anytime and anywhere and enjoy high-quality, real time and smooth conference experience.
