3G演进

章节摘录

　　The size and weight of the mobile terminals have been reduced dramatically during the past 20 years. The standby and talk times have also been extended dramatically and the end users do not need to re-charge their devices every day. Simple black-and-white （or brown-and-gray） numerical screens have evolved into color screens capable of showing digital photos at good quality. Mega- pixel-capable digital cameras have been added making the device more attractive to use. Thus, the mobile device has become a multi-purpose device, not only a mobile phone for voice communications.　　In parallel to the technical development of the mobile devices, the mobile- communication technologies are developed to meet the demands of the new serv- ices enabled, and also to enable them wireless. The development of the digital signal processors enables more advanced receivers capable of processing mega- bits of data in a short time, and the introduction of the optical fibers enables high-speed network connections to the base stations. In sum, this enables a fast access to information on the Internet as well as a short roundtrip time for normal communications. Thus, new and fancier services are enabled by the technical development of the devices, and new and more efficient mobile-communication systems are enabled by a similar technical development.　　2.1.2 Services Delivering services to the end users is the fundamental goal of any mobile- communication system. Knowing them, understanding them, managing them, and charging them properly is the key for success. It is also the most difficult task being faced by the engineers developing the mobile-communication system of the future. It is very difficult to predict what service（s） will be popular in a 5- to 10-year perspective. In fact, the engineers have to design a system that can adapt to any service that might become popular and used in the future. Unfortunately, there are also technical limitations that need to be understood, and also the tech- nical innovations that in the future enable new services.　　2.1.2.1　Internet and IP technology The success of the Internet and the IP-based services delivered over the Internet is more and more going wireless. This means that the mobile-communication systems are delivering more and more IP-based services, from the best effort- Internet data to voice-over-IP, for example in the shape of push-to-ta　　k （PoC）. Furthermore, in the wireless environment it is more natural to use, for exam- ple, location-based services and tracking services than in the fixed environment.

前言

　　During the past years， there has been a quickly rising interest in radio access tech- nologies for providing mobile as well as nomadic and fixed services for voice， video， and data. The difference in design， implementation， and use between telecom and data com technologies is also getting more blurred. One example is cellular technologies from the telecom world being used for broadband data and wireless LAN from the data com world being used for voice over IP.　　Today， the most widespread radio access technology for mobile communication is digital cellular， with the number of users passing 3 billion by 2007， which is almost half of the worlds population. It has emerged from early deployments of an expensive voice service for a few car-borne users， to todays widespread use of third generation mobile-communication devices that provide a range of mobile services and often include camera， MP3 player， and PDA functions. With this widespread use and increasing interest in 3G， a continuing evolution ahead is foreseen.　　This book describes the evolution of 3G digital cellular into an advanced broadband mobile access. The focus of this book is on the evolution of the 3G mobile communication as developed in the 3GPP （Third Generation Partnership Project） standardization， looking at the radio access and access network evolution.　　This book is divided into five parts. Part I gives the background to 3G and its evolution， looking also at the different standards bodies and organizations involved in the process of defining 3G. It is followed by a discussion of the rea- sons and driving forces behind the 3G evolution. Part II gives a deeper insight into some of the technologies that are included， or are expected to be included as part of the 3G evolution. Because of its generic nature， Part II can be used as a background not only for the evolution steps taken in 3GPP as described in this book， but also for readers that want to understand the technology behind other systems， such as WiMAX and CDMA2000.
