Radio Communication Module Location-Based Compliance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices, such as radio communication modules, that do not meet the technical standards of a country can be used illegally when brought into Japan, especially during repairs or imports, as they are not required to comply with Japanese technical standards for international roaming or when brought in by individuals from overseas.
Innovation Solution
A radio communication module with a controller that stops or modifies transmission operations based on set information specific to a communication carrier's specifications, ensuring compliance with the technical standards of the country in which it is used, by determining the location through MCC codes or GNSS data and adjusting settings to prevent illegal use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal device is configured to operate with set information accorded to the specification of a communication carrier of a first country, then the device can operate normally in that country, but when the device is used in a second country different from the first country, it may violate the technical standards of the second country
Solution Approach 1:
The controller is configured to determine the current country of operation before the terminal device establishes radio communication. Based on this predetermined location information, the controller proactively selects appropriate set information that complies with the technical standards of the current country, preventing legal compliance issues before they occur
Solution Approach 2:
The terminal device dynamically switches between different set information based on the detected current country. The controller automatically changes the operational parameters to match the technical standards of the current location, enabling the device to adapt its behavior according to the geographical location rather than being fixed to a single country's specifications
2Ease of operation
If the radio communication module allows transmission operation with foreign set information, then international roaming and repair functions are enabled, but technical standards of the host country may be violated
Solution Approach 1:
The controller acts as an intermediary between the radio communicator and the set information storage. It intercepts the set information based on the current country determination and selectively applies appropriate configurations, ensuring that the radio communication operation always uses set information that complies with the host country's technical standards while still enabling international functionality
3Adaptability or versatility
If the terminal device stores multiple sets of set information for different countries, then it can operate in multiple countries, but the device complexity increases
Solution Approach 1:
The controller automatically determines the current country using location information (such as MCC codes from SIM cards or GNSS data) and autonomously selects the appropriate set information without requiring user intervention. This self-service mechanism simplifies the user experience while maintaining the capability to operate in multiple countries

AI summary
A radio communication module 10 includes: a radio communicator 12 configured to perform radio communication; a storage 14 configured to store set information that sets operation relating to radio communication; and a controller 13 configured to stop at least transmission operation of the radio communicator 12 or change at least a part of set information accorded to a specification of a communication carrier of a first country, when it is set so as to operate by using the set information accorded to the specification of the communication carrier of the first county and the radio communication module 10 locates in a second country different to the first country.
