Mobile Terminal Number Display Adaptation via SIM MCC Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals manufactured for different countries require customized number display styles, leading to increased manufacturing costs and user discomfort when switching between countries, as existing methods involve producing multiple software versions.
Innovation Solution
Enabling an International Mobile Subscriber Identity (IMSI) automatic match function on mobile terminals to read and parse SIM card information, matching it with a Mobile Country Code (MCC) number format list to display numbers in the accustomed format for each country.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple software versions are produced for different countries, then number display style adaptation is achieved, but manufacturing cost increases
Solution Approach 1:
The patent implements a single universal software version that can automatically adapt to different countries' number display styles by detecting the SIM card's MCC information. The system uses a unified codebase with dynamic configuration based on the inserted SIM card, eliminating the need for multiple country-specific software versions while maintaining full adaptability to local number formats.
Solution Approach 2:
The patent changes the display format parameter dynamically based on the detected MCC code from the SIM card. Instead of having different software versions for different countries, the system modifies the number display parameter (format string) according to the country code detected from the inserted SIM card, allowing a single software version to adapt to multiple countries.
2Ease of operation
If customized software versions are produced for different countries, then user comfort is improved, but device complexity increases
Solution Approach 1:
The system automatically detects the user's country based on the SIM card's MCC information and self-configures the appropriate number display format without requiring user intervention or manual selection. The device serves itself by automatically adapting to the local format, improving user comfort while avoiding the complexity of managing multiple software versions or user configurations.
Solution Approach 2:
The patent pre-configures multiple number display formats corresponding to different MCC codes in advance. When a SIM card is inserted, the system quickly matches the MCC code with the pre-configured formats and applies the appropriate display style immediately, providing user comfort from the first use without requiring complex setup or version switching.
3Ease of manufacture
If a single software version is used for all countries, then manufacturing cost is reduced, but number display style adaptation is lost
Solution Approach 1:
The patent introduces an intermediary mechanism - the MCC code detection and format matching module - that bridges the single software version and multiple country-specific display styles. This intermediary automatically detects the user's country through the SIM card's MCC information and selects the appropriate display format, enabling a single software version to provide adaptability to multiple countries without requiring multiple versions.

AI summary
The present invention provides a method and device for number display based on the mobile terminal and a mobile terminal. The method includes: an International Mobile Subscriber Identity, IMSI, automatic match function is enabled according to a user selection, IMSI information in a Subscriber Identity Module, SIM, card is read, the IMSI information is parsed to acquire Mobile Country Code, MCC, information; an MCC number format list is matched according to the MCC information to acquire and store a corresponding number display format; and when a user opens a dialling interface to input a number, the number is displayed according to the corresponding number display format. The present invention solves the problem of not being adapted to a display style of the mobile terminal, and has the beneficial effects that an accustomed phone number display style of a corresponding country is automatically matched according to a phone number input by a user and the phone number is displayed according to the number display style, thereby enhancing system performance and improving user experience.
