Abstract:

  A modern mobile phone supports many features: voice and data calls, text messaging, personal information management like phonebooks and calendars, WAP browsing, games, alarm clock, etc. All these features are packaged into a handset with a small display and a special purpose keypad. The limited user interface and the seamless intertwining of logically separate features cause many interactions between the software components in the UI of mobile phones. In this paper, we present an overview of our approach to modelling feature interactions in Nokia's mobile phones with explicit behavioral models of features. We use Coloured Petri Nets as the modeling language and the tool Design/CPN that provides a graphical, interactive user interface for constructing and simulating Coloured Petri Nets. We describe at a general level how we have created a graphical user interface for controlling and observing the simulations of models through an on-screen mock-up of a mobile phone. Then, we discuss the conrete results we have achieved by using our approach.
