Abstract
The Short Message Service (SMS) in the GSM system is designed to provide a vehicle for delivering length-limited data messages between mobile users. This paper describes a prototype system that is capable of providing a Short Message Command Interface (SMCI) for mobile users employing GSM-enabled terminal devices to access remote PCs or workstations by executing DOS or UNIX commands. In addition, based on our successful testing of the implemented SMCI prototype system, we further devise a framework of the Home Network Service Centre by expanding this prototype system for mobile users to access emerging information appliances connected by Home Networks in a reliable and cost-efficient way. The SMCI prototype system is composed of three parts: the SMCI Clients, the SMCI Servers, and the SMCI Gateway. The SMCI Clients are mobile users who can send commands to the SMCI Servers and receive results from the SMCI Servers both through the SMCI Gateway. By taking advantage of this prototype system and the proposed framework, mobile users can login remote machines and can access value-added services as well as Home Network services provided on those machines or information appliances. © 2001 Academic Press.
