GLOBAL MESSAGING: AN EFFICIENT MOBILE COMMUNICATION SYSTEM THROUGH THE INTEGRATION OF SATELLITE AND TERRESTRIAL SERVICES

Research in the telecommunication field is heavily involved in reaching two fundamental goals: a better quality of service at reasonable costs, and more chances to communicate anywhere in the world. The present transport systems should take into account the results carried out in the TLC field in order to fulfil the needs for business globalization, for security improvement and for a more efficient use of the transport resources. The monitoring and supervision of the fleets, the flow control of the goods, the immediate localization of vehicles that are in critical conditions, all need a TLC infrastructure that make possible a reliable information exchange between mobiles and the central control facilities. This paper, after giving an overview of the existing or planned messaging systems, presents some integration strategies in order to exploit the synergetic interaction between them.
