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.
