ABSTRACT

Development productivity and quality improvements, as well as cost
reduction, are the main factors for the need and popularity of software
reuse. In addition, the increasing demand for large and complex software
systems, and the difficulty of supplying them on time and within the
budget make the reusability concept attractive. In this context,
this work provides a framework for mobile wireless communication
systems that allows designers to apply reusability to the early
stages of the development process. In order to achieve this, firstly,
existing systems are investigated and common network entities and their
respective functionalities are identified. Secondly, the framework is
generated based on these commonalities with a technique called Use Case
Maps.
