As the number and type of communications systems in use around the world multiplies so the need for gateways to allow these systems to interoperate increases. This is particularly true for global satellite systems that potentially need to interoperate with systems complying to widely different standards around the world. The ETSI proposed S-UMTS system and (significant) bandwidth allocation is intended to provide an important overlay to future terrestrial 3rd Generation networks. S-UMTS is specifically targeted at providing services in remote regions, or potentially just as important, when out of coverage of the subscriber's home network or a network with a suitable roaming agreement. Thus, satellite/terrestrial interoperability is a key issue to enable subscribers the standard and diversity of service offered by terrestrial systems plus the broad coverage offered by satellite systems. There are considerable technical challenges involved in achieving true interoperability between networks in the 2.5 and 3G world, and therefore in achieving the true vision of S-UMTS. One of the key technical issues is inter-working between different standards, which will continue into the 3G period due to the large number of different types of network (GSM, IS-41, PDC, CDMA, satellite, etc) employed throughout the world. Packet data roaming onto satellite networks is set to become a new important capability for business users in support of the global mobile office as GPRS and 3G services become more widespread. When out of terrestrial network coverage or when the availability of standard call or data transfer charges globally is needed, roaming onto satellite networks provides a very attractive solution. Using the Inmarsat system as an example this paper addresses how interoperability between satellite and terrestrial networks can be assured through the use of standard computer equipment running software-based gateways.
