Most smartphones feature an app called “phone”. Now model the behaviors of this software system using a UML state diagram.The related customer requirements description includes the following:Initially the system is idle just showing the dial pad.When the user makes a phone call, the system starts dialing the number entered.If the user cancels the phone call when the system is still dialing, the system will get back to be idle.When the dialed party picks up the call, the system will become connected to the dialed party, and when the call is done, the system returns to show the dial pad and be idle. When the system is idle, the user can configure the app (e.g., setting the ring sound). If the user starts the configuration, then the system gets into the setting condition, and it gets back to be idle when the configuration is finished.

Question

Most smartphones feature an app called “phone”. Now model the behaviors of this software system using a UML state diagram.

The related customer requirements description includes the following:

Initially the system is idle just showing the dial pad.
When the user makes a phone call, the system starts dialing the number entered.
If the user cancels the phone call when the system is still dialing, the system will get back to be idle.
When the dialed party picks up the call, the system will become connected to the dialed party, and when the call is done, the system returns to show the dial pad and be idle.
When the system is idle, the user can configure the app (e.g., setting the ring sound). If the user starts the configuration, then the system gets into the setting condition, and it gets back to be idle when the configuration is finished.
