Beyond Third Generation Cellular Networks: The Integration of Internet and Telephony Technology

The telephony network has evolved over the last 120 years into one of the most ubiquitous and complex technological systems known to humankind. Yet at the end of the 20th Century, the engineering design principles that underlie this great technical achievement are being challenged. The fastest growing sector of the telecommunications industry is cellular services, introducing new demands for user and handset mobility in the future network. Cellular handsets are sophisticated electronic devices able to
perform advanced digital signal processing, extensive user interface support, and will ultimately provide many personal information management functions. Following a similar explosive growth trend is the number of Internet subscribers. Internet usage counters many of the engineering assumptions about the telephone network, which has been carefully engineered to deliver outstanding performance for real-time voice. In this talk, we will review these trends and technologies, and will describe a new research project at UC Berkeley, called ICEBERG (Internet-based Core for cEllular networks BEyond the thiRd Generation). The project is exploring how packet switching technology can be exploited to integrate mobile handsets, cellular infrastructure, voice and data
applications, and the Internet.
