Mobile Terminal Automatic Dialing via Country Code Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile communication terminals face inconvenience when making international or local calls while traveling, as they need to manually input different international access codes and country codes, and stored phone numbers become unusable across different countries.
Innovation Solution
A method and apparatus for a mobile communication terminal that automatically determines the country code based on the terminal's location and changes the phone number format between international and local systems, allowing for seamless dialing without requiring users to input access codes and country codes manually.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually input international access codes and country codes for international calls, then call functionality is achieved, but operation complexity and time consumption increase
Solution Approach 1:
The terminal pre-stores international access codes and country codes in a database before the user needs them. When making an international call, the system automatically retrieves and inputs the required codes based on the destination country, eliminating the need for users to manually input these codes during the calling process.
Solution Approach 2:
The terminal system automatically performs the function of selecting and inputting international access codes and country codes without requiring user intervention. The system detects the destination country and autonomously completes the code input process, making the terminal serve itself in the code input task.
2Adaptability or versatility
If users preset international access codes and country codes for each phone number, then calling convenience is improved, but adaptability to different countries decreases
Solution Approach 1:
The terminal implements a universal phone number management system where a single stored phone number can be used internationally without modification. The system automatically adapts the phone number format and adds appropriate access codes and country codes based on the current location and destination country, making the phone book universally applicable across different countries.
Solution Approach 2:
The system introduces an intermediary processing layer between the stored phone number and the actual dialing process. This intermediary automatically inserts the appropriate international access code and country code based on the destination country, allowing the original phone number to remain unchanged while achieving international calling functionality.
3Productivity
If the terminal automatically determines country code based on location, then calling process is simplified, but system complexity increases
Solution Approach 1:
The terminal uses feedback from the user's current location (detected via GPS or network information) and the destination country to automatically determine and select the appropriate international access code and country code. This feedback mechanism allows the system to adaptively adjust the dialing sequence without manual input.
Solution Approach 2:
The patent replaces the manual mechanical process of looking up and inputting codes with an automated electronic system. The terminal's processor automatically queries the stored database, retrieves the appropriate codes, and inputs them programmatically, substituting manual operations with automated electronic processing.

AI summary
A method and apparatus for providing automatic international and local call dialing in a mobile communication terminal. The apparatus includes a country identification unit for receiving country identification information from a network in which the mobile communication terminal is currently located; a memory for storing country identification information, a country codes, and international access codes corresponding to the country codes; and a controller for extracting from the memory a country code corresponding to the country identification information received from the country identification unit, comparing the extracted country code with a country code included in a phone number for an outgoing call, and making a local call or an international call according to whether the country codes are identical.
