【Abstract】 UML is a new object-oriented modeling language. This article introduces its main features, recent development and perspective. Satellite mobile communications will play an important role in future, but it is not easy to design a good system of it. By exploring the modeling of designing software of satellite mobile communications system with UML, the form, features and application of it are also expatiated, and hence a preliminary and complete concept of UML is formed.更多还原
