1 Introduction

​ Based on the capabilities of the system platform, design and develop call applications, providing voice calls, video calls, call settings, mobile network settings, SIM card management settings, emergency dialing, and functions for adding personal emergency information. Build models from different perspectives and design the architecture of the call application to ensure security, resilience, reliability, privacy, etc. while satisfying basic functions.

1.2 Introduction to Architecture Diagram:

The application adopts a multi-module design as a whole, which is used to handle the business logic and data management of the call application and the interface display. Each module follows the division principle of the above architecture. The functions of each module are as follows:

• FA-UI: Interface display responsible for handling and user interaction
• Public Module: responsible for the processing of public methods, assisting in the display of the connected interface, the interaction of business logic and data management
• Adapter Module: responsible for business logic and data management

The important classes and their functions in each layer of the application are shown in the following table

Module	Function	Class Name	Function
FA-UI	Interface Display	Voice Calls FA	Mainly provides user interface related to voice calls
FA-UI	Interface Display	video Calls FA	Mainly provide video call related user interface
FA-UI	Interface display	SIMCard Management FA	SIM card related user interaction management interface
FA-UI	Interface Display	Emergency Dialing FA	Emergency Dialing User Interface
FA-UI	Interface display	Call Settings FA	User interaction interface related to call settings
FA-UI	Interface Display	Personal Emergency Information FA	Personal Emergency Number User Interface
FA-UI	Interface Display	Mobile NetWork Settings FA	Mobile NetWork Settings User Interface
Public Module	Common Components and Methods	Common Components	Processing Classes for Public Components
Adapter Module	Business Processing Interface	Dial Module	Handling Dial-related Functions
Adapter Module	Business Processing Interface	Status Monitoring Module	Monitor Business Status Module
