PERSONAL COMMUNICATIONS SERVICES THROUGH THE EVOLUTION OF FIXED AND MOBILE COMMUNICATIONS AND THE INTELLIGENT NETWORK CONCEPT

New telecommunications services tend to consider fixed network subscri bers' requirements as well as mobile network subscribers' requirements . On one hand, subscribers of fixed networks would like to benefit Fro m the mobility offered in mobile networks. On the other hand, mobile s ubscribers would like to access to services inherent in fixed networks . Personal communications services meet this trend while allowing Fixe d and mobile convergence. In this environment, the application of inte lligent networks to fixed and mobile networks is very convenient to re alize personal communications services. Thus, the natural advancement of telecommunications systems (fixed and mobile) consists in the defin ition of new telecommunications architectures which take into account technologies from both fixed and mobile environments.
