碩士 === 國立交通大學 === 資訊管理學程碩士班 === 90 === While there are numerous books offering tips on the design of distributed systems, and some application vendors who say that their useful tools are indispensable for distributed design, the only way to fully understand the issues involved in the design of a distributed system is to actually attemp a design. There is no substitute for experience. It is critical to remember that Voice Mail System distribution is a design and analysis issue. It follows that any generally accepted analysis methodology will suffice for documenting the requirements of the system. The main purpose of this thesis is trying to collect relevant traffic reports, analyze the GSM subscribers’ telephone behavior and using traffic theory of Erlang B fomula, to generalize a common methodology of how to design a distributed Voice Mail System network. By studing the relevant traffic reports, the GSM subscribers’ telephone behavior of KG Telecommunications and using the traffic theory of Erlang B fomula. We found a methodology of how to provision the Voice Mail subscribers more effectively. The enterprise can successfully reduce the rental cost of the transmission lines by using this methodology.
