Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile terminals face inconvenience and inefficiency in manually setting language, time, and character encoding schemes when traveling or using devices in different countries, leading to SMS transmission and reception failures due to mismatched encoding schemes.
Innovation Solution
A method and apparatus that automatically detect country information from subscriber identification data to set relevant information such as language, time, and character encoding schemes in mobile terminals, eliminating the need for manual user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual setting of language, time, and character encoding schemes is required, then the mobile terminal can be used in different countries, but the user experiences inconvenience and time loss due to manual configuration
Solution Approach 1:
The mobile terminal automatically detects country information from the inserted SIM card and self-configures language, time format, and character encoding schemes without requiring user intervention. The system serves itself by extracting country codes from subscriber identification information and automatically applying the appropriate regional settings.
Solution Approach 2:
The country information and corresponding setting parameters are pre-configured in the mobile terminal's memory before the user travels. When a SIM card is inserted, the system quickly retrieves and applies the appropriate pre-prepared settings based on the detected country code, eliminating the need for real-time manual configuration.
2Reliability
If manual setting of character encoding scheme is required, then SMS transmission can be achieved, but the process becomes troublesome and inefficient
Solution Approach 1:
The mobile terminal automatically determines the appropriate character encoding scheme by detecting the country information from the SIM card and configures itself accordingly. This self-configuration ensures SMS transmission reliability while completely eliminating the need for users to manually set encoding parameters.
Solution Approach 2:
The country information stored in the SIM card acts as an intermediary that bridges the user and the appropriate character encoding scheme. Instead of requiring users to directly select encoding schemes, the system uses the SIM card's country data as a mediator to automatically determine and apply the correct encoding.
3Reliability
If the mobile terminal uses local encoding scheme based on local information, then character encoding works for local language, but SMS transmission fails when traveling to foreign countries with different encoding schemes
Solution Approach 1:
The character encoding scheme is no longer fixed to a single local setting but dynamically changes based on the detected country information from the SIM card. The system automatically adapts the encoding scheme to match the user's current location, ensuring SMS transmission reliability across different countries.
Solution Approach 2:
The mobile terminal changes the character encoding parameter based on the country code detected from the SIM card. When the user travels to a different country, the system automatically modifies the encoding parameter to match the local standard, ensuring compatibility and successful SMS transmission in the foreign country.
