Mobile telephone architecture details |
The mobile telephone architecture sample describes a fictional mobile telephone network in which mobile telephones communicate with each other. The architecture consists of mobile telephones and a wireless network that routes calls. The following figure illustrates the architecture:
The detailed telephone model is based on a real-world mobile telephone. The model consists of a speaker, ringer, display, storage, and central telephone device that is modeled as a controller class. The user uses the telephone to place a call to another user. When the user places a call, it is routed through the wireless network. The wireless network is a generalized representation of a wireless network and base station architecture. The wireless network processes the incoming call, locates the recipient, determines whether the recipient's telephone is idle, and places the call. The mobile telephone architecture consists of two models. The Mobile telephone use-case model contains the use cases and activity diagrams that describe how the users interact with the system. The Mobile telephone architecture model builds on the use-case model and contains sequence diagrams, domain diagrams, and state machine diagrams that model the static and dynamic information of the system. |
