Call origination and termination strategies for mobile statellite systems

摘要

To achieve the global ubiquity promised, Mobile Satellite Service ("MSS") carriers will need to resolve many terrestrial issues including: a user friendly dialing regime that integrates MSS networks into the existing direct distance dialing system, transborder use of transceivers, and low cost interconnection of gateway facilites with the public switched telephoe network. This paper will examine call origination/termination strategies of several representative MSS operators with an eye toward identifying exposure to unanticipated expenses, particularly that imposed by the accounting rate settlements process used by carriers to divide international toll revenues. The paper concludes that users must have unlimited opportunities to use their MSS telephones across political boundaries, dialing must work seamlessly withthe preexisting numbering system and MSS operators will have to confront the financial impact of the accounting rate regime.
