The transition from physical to digital music distribution is bound to have profound implications on the music industry. So far, most of the activity related to digital music distribution has been centred on the fixed Internet. In the meantime, mobile operators have been making significant investments in extending their network capabilities to support data services. This paper includes an analysis of the current state of digital music distribution, as well as future prospects enabled by the evolution of mobile networks. We build on this by presenting and analysing a novel model for music download over mobile networks based on the convergence between the music download and radio broadcast services.

Key issues regarding the operation of the broadband integrated services digital network (BISDN) via satellite are presented herein. The specific issues, challenges, and their resolutions are detailed. In particular, the impact of error characteristics and propagation delay on the operation of BISDN via satellite is discussed. Solutions are presented for removing adverse effects and providing high-quality service to users of BISDN via satellite.

he conducted research on systems for information dissemination and personalization through filtering of the stream of received information articles. Before that he conducted research on broadband systems architecture and participated in constructing an early prototype of a broadband switch. With several colleagues he patented a non-blocking self-routeing switch suitable for ATM. Prior to joining Bellcore he worked for AT&T Bell Labs and the U.S. National Oceanic and Atmospheric Administration. Howard received a BS in Mathematics and Psychology from the University of Colorado in 1974
a Bachelor of Electrical Engineering (with high distinction) from the University of Minnesota in 1979 and a MS in Electrical Engineering from the University of California Berkeley in 1980. From 1977 to 1980
he worked on database and system software development for GTE Northlake IL. From 1980 to 1983 he was at AT&T Bell Laboratories Naperville IL where he designed and implemented software for the DMERT operating system of the 3B20D processor. He joined Bellcore in 1984 where he has worked on ATM was involved in BISDN standards participating in T1S1 and CCITT Study Group XVIII. He is currently involved in exploratory'research on signalling that is known as object-oriented call control working co-operatively with European experts in the RACE/MAGIC project and participating in T1S1 and CCITT Study Group XI. He has been with Bellcore as a Member of Technical Staff since August 1992 working on routeing
resource allocation connection management and signalling for BISDN. His research interests include traffic theory switching systems and ATM networks. From 1987 to 1990 he worked on a secure
jam-resistant communications system for the United States Armed Forces at Plessey Electronics System Corporation Wayne New Jersey. He received the M.E. degree in Electrical Engineering from Stevens Institute of Technology Hoboken New Jersey in 1

The experimental ATM network services environment (EXPANSE) prototype provides an experimental testbed for multimedia multiparty telecommunications services over heterogeneous communications networks. The EXPANSE software architecture supports the functional separation of call and connection control. At the call control layer an object-oriented, transaction-based call model provides for the co-ordination of the negotiations among users for the establishment, modification and disconnection of telecommunications services. The connection control layer provides an object-oriented protocol for the dynamic establishment, modification and release of network connections which include the control and allocation of network resources required for multimedia multiparty services. The EXPANSE software includes an application programming interface (API) to the signalling protocol at the call control level. The API provides a uniform and powerful interface to the call model and allows different applications to co-ordinate the control of local resources and session state.
