The Research Of Flow Of Short Message Based On Traffic Flow Theory

Since the short message came into people's daily lives with the GSM mobile communication system, Short Message Service (SMS) have been developing on a very rapid pace. The number of those who use short messages with their families and friends to communicate grows annually and geometrically. SMS, in less than a decade, have become a unique and indispensable way of communication and contact among modern people. Short Message Service not only improves people's lifestyle, the same time, it also contains enormous business opportunities.A wide range of value-added services enrich short message content, but also they increase short message transmission network costs. At the same time, by the use of short message and a rapid increase in the number of people dependent on the short messages, short message transmission network is faced with a lot of load pressure. As a Short Message Service Center (SMSC), one of the core components of the network, whether it can run properly and keep a quantitative and qualitative state of the work under a intense load pressure, often is the key to a short evaluation of the networks.In this paper, Short Message Service is studied in depth and especially Short Message Service Center. Subject to traffic flow theory inspired a short message queuing model to simulate the short message service center, which lays a foundation for further discussion on the performance of Short Message Service Center.In addition, the model of the short message service center presented in this paper is exploited to make a theoretical study of the performance of SMSC. The roles of system capacity, accessing ability and load intensity are discussed to improve the performance of Short Message Service Center, and comments and suggestions are given.
