A method to create graphical user interfaces in telecommunication services specified in SDL

摘要

Technical advances in communication networks and terminal equipment make possible the provision of a wide range of new and appealing telecommunication services. However, the increasing user demand and the strong market competition require that the creation of those services is efficient and fast, and that they have attractive interfaces. The complexity of networks and distributed systems, which support those services, renders the usage of formal specification languages, such as SDL, almost mandatory in their development. According to some authors, fifty percent of the total time necessary to develop applications is spent in building and testing graphical interfaces for different platforms. An efficient methodology to create graphical interfaces for telecommunication services specified in SDL is presented.
