ABSTRACT
The popularity and evolution of mobile devices like laptops, mobile phones and Personal Digital Assistants (PDA), and the evolution of fast mobile networks in the last decade, have made it possible to increase the complexity of mobile applications and services provided to end-users. It is also a spectacular growth in multimedia communication especially via the World Wide Web. This paper explore some of the current technology of mobile devices, mobile networks and multimedia systems, and is based on the exploration outline some issues for design and development of mobile multimedia systems in 4G Mobile Communication System. Fourth-generation mobile communication systems will combine standardized streaming with a range of unique services to provide high-quality content ( Multimedia ) that meets the specific needs of the rapidly growing mobile market. By offering higher data-transmission rates up to 20 Mbps more than 3G for wide-area coverage and local-area coverage, 4G systems will be able to provide high quality streamed content to the rapidly growing mobile market.
INTRODUCTION
Many portal sites offer streaming audio and video services for accessing news and entertainment content on the Internet from a PC. The term multimedia streaming means that there are more than one media type involved in the communication, e.g. text and graphics, voice, animations, video and audio. We defines multimedia to denote the property of handling a variety of representation media in an integrated manner. This means that the various sources of media types are integrated into a single system framework. Currently, three incompatible proprietary solutions offered by Real Networks, Microsoft, and Apple dominate the Internet streaming software market. In the near future, third-generation mobile communication systems will extend the scope of today_s Internet streaming solutions by introducing standardized streaming services, targeting the mobile user_s specific needs. By offering higher data-transmission rates up to 20 Mbps more than 3G for wide-area coverage and local-area coverage, 4G systems will be able to provide high quality streamed content to the rapidly growing mobile market. In addition to higher data rates, these systems also will offer value-added applications supported by an underlying network that combines streaming services with a range of unique mobile specific services such as Multimedia content, geographical positioning, user profiling, and mobile payment. Mobile cinema ticketing is one example of such a service. First, the mobile network or a terminal integrated positioning system such as GPS would determine the user_s geographical location. Then, the service would access a cinema database to generate a list of nearby movie theatres and a user profile database to determine what kind of movies the user likes best. Based on the geographical location information and user-defined preferences, the service would offer the user a selection of available movies and show times. The user would then have the option of using the mobile device to view corresponding movie trailers through a streaming service. Upon choosing a film, the user could purchase a ticket through payment software on the mobile device. This and other mobile application scenarios present numerous challenges, such as how to provide spectrum efficient streaming services over varied radio-access networks to different types of end-user terminals. Our standard-based Interactive Media platform addresses these challenges by using an architecture that fits seamlessly into 4G mobile communication systems. An integral part of this architecture is a streaming proxy, which acts on both the service and transport levels. It is flexible enough to deal with different operator requirements and that it can provide high-quality streaming services in a mobile application environment
.2. 4G MOBILE COMMUNICATION SYSTEMS
International Mobile Telecommu-nications - 2000 (IMT-2000) and the Universal Mobile Telecommunications System (UMTS) will be among the first 3G mobile communication systems to offer wireless wideband multimedia services using the Internet protocol. Two important technological changes will facilitate this advancement. The first change is a shift from last-generation radio-access technologies such as the global system for mobile (GSM) communication, CDMAOne (an IS-95 code division multiple access standard), and personal digital cellular (PDC) toward more sophisticated systems with higher data-transfer rates such as the enhanced data. fourth-generation mobile communication systems will combine standardized streaming with a range of unique services to provide high-quality content that meets the specific needs of the rapidly growing mobile market. GSM environment (EDGE), wideband CDMA (WCDMA), and cdma2000. As Figure 1 illustrates, the second important technology shift is from a vertically integrated to a horizontally layered service environment. A horizontally layered 4G service network seamlessly integrates Internet protocol transport into a mobile service environment with a variety of access networks, opening up many new opportunities for IP-based mobile applications. For example, mobile terminals will be able to access existing Internet content through protocols and markup languages such as WAP and WML that are optimized for wireless application scenarios. 4G mobile communications will have transmission rates up to 20 Mbps_ higher than of 3G. The technology is expected to be available by the year 2010. 4G is being developed with the following objectives: 1. Speeds up to 50 times higher than of 3G. However, the actual available bandwidth of 4G is expected to be about 10 Mbps. 2. Three-dimensional virtual reality_imagine personal video avatars and realistic holograms, and the ability to feel as if you are present at an event even if you are not. People, places, and products will be able to interact as the cyber and real worlds merge. 3. Increased interaction between corroborating technologies; the smart card in your phone will automatically pay for or will tell your car to warm up in the morning as your phone has noted you leaving the house. We can use new technology such as CDMA wireless access technology, advanced antenna systems, next-generation mobile Internet, quality of service, power amplifier technology, and wireless access networks in 4G mobile communication system.4G applications include high-performance streaming of multimedia content based on agent technology and scaleable media coding methods.4G will solve problems like limited bandwidth in 3G when people are moving and uncertainty about the availability of bandwidth for streaming to all users at all times. The 4G networks will also provide access to support services such as authentication, security, and billing mechanisms as well as mobile-specific services
