Wireless carriers are seeking to add new services to their offerings over a converged telecommunications and data network. Mobile access to Chapter 8 - Next-Generation OSS data services is revolutionizing computing and is creating new market opportunities for equipment makers, network operators, mobility-based service providers and a variety of content providers. In the world of 3G, wireless service providers will deliver high-speed telephony, video and data services over a common IP backbone. 3G wireless technologies allow for much greater channel capacities for voice and higher speeds for wireless data, enabling mobile handsets to send/receive data at speeds up to 144 Kbps. Along with high data rates, 3G also allows for solutions based on mobile Internet access. IP mobility, a key concept of 3G, allows for innovative mobile services such as messaging and location-based content. Other key components of a 3G integrated infrastructure include Home Agents, Foreign Agents, Packet Data Serving Nodes, AAA servers and possibly softswitches.
