The growth of telecommunications has been largely based on mobile and data services in the past 10 years and the growth will continue. For instance, it is forecasted that after 2005 the mobile traffic turnover in Europe will exceed that of fixed telephone traffic and the penetration of Internet access through mobile will exceed that of fixed access. It is expected that the new value added services will be Internet-based and the IP traffic will outweigh the amount of traditional ISDN based telephone traffic. The transition from the existing telecommunications services to mobile and Internet based ones will change the service infrastructure as well as the customer and service management structures. In wireless communications there are several new standards being developed and implemented to improve the data transmission rate over radio channels, to combine both voice, packet data and multimedia services in the terminals and to improve the service quality and usability. Narrow band packet radio standards such as General Packet Radio Service (GPRS) and i-Mode are already operative and broadband IMT-2000 standards, also called as Third Generation (3G) Mobile, have been developed in Japan, Europe and US. At the same time Wireless LAN and Bluetooth technologies mature and provide short-range data access to terminal devices. The emerging new technologies create opportunities not only to incumbent teleoperators but also to new network operators, IT companies and new service and content providers.

Smart Networks comprises the proceedings of Smartnet'2002, the seventh conference on Intelligence in Networks, which was sponsored by the International Federation for Information Processing (IFIP) and organized by Working Group 6.7. It was held in Saariselka, Finland, in April 2002. The conference series closely reflects the developments in networking. Currently we are facing two conflicting trends: the increasing popularity of the Internet and the growth of mobile communications. The traditional Internet approach is to regard a network as a dummy pipe of bits and place all the intelligence in the end-devices. The traditional telecom approach is to regard the end-devices as dummy senders or receivers of bits and to put all the intelligence in the network. For fixed-line access to the Internet using a powerful PC, the Internet approach is plausible. However, for a nomadic user, who sometimes accesses services through a fixed-line Internet connection and, at other times, through a wireless connection using a restricted-capability access device, the situation becomes intolerable. Intelligence needs to be distributed and partially replicated in end-user devices, access networks, and the core network.The presentations in this volume consider these new trends and cover three major topics: platform software, services, and protocols. The sessions on platform software address various aspects of software infrastructure in networks including object-orientation, components, agents, and plug-and-play. The session on services includes interactive TV, group communication, and location awareness. The session on protocols discusses bandwidth brokers, authentication, and protocol testing.

Substantial new breakthroughs are happening in telecommunications technology.
