Mobile Device Channel Selection by Region
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile electronic devices face legal issues when traveling across national borders due to the lack of uniformity in licensed radio frequency spectrums, as channels permissible in one country may be proprietary in another, potentially leading to illegal wireless communication.
Innovation Solution
A method and device that automatically determine a legal communication channel range by using geographical region information to select appropriate channels within the unlicensed spectrum, utilizing a location determining module, wireless interface, and processing unit to retrieve country-specific channel information from a mapping table or external APs, ensuring compliance with regional regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile electronic device uses a fixed communication channel for P2P communication, then communication simplicity is maintained, but the device may violate local radio frequency regulations when traveling across national borders
Solution Approach 1:
The patent implements dynamic channel selection by determining the current geographical region and automatically selecting an appropriate communication channel from a predefined mapping table that corresponds to the detected region. This allows the communication channel to adapt dynamically based on location, resolving the contradiction between maintaining simple operation and ensuring regulatory compliance across different countries
Solution Approach 2:
The patent introduces a mapping table as an intermediary component that stores the correspondence between geographical regions and legal communication channels. This mapping table acts as a mediator between the location determining module and the wireless communication interface, automatically translating location information into compliant channel selections without requiring user intervention
2Reliability
If a mobile electronic device automatically determines geographical region and selects communication channels, then regulatory compliance is ensured, but device complexity increases
Solution Approach 1:
The patent segments the channel selection process into distinct functional modules: a location determining module that acquires geographical information, a mapping table that stores region-channel correspondences, and a channel selection module that performs the actual selection. This segmentation allows each component to perform its function independently, reducing overall system complexity while ensuring regulatory compliance
Solution Approach 2:
The patent pre-populates a mapping table with the correspondence between geographical regions and legal communication channels before the device is used. This preliminary action eliminates the need for real-time complex calculations or queries during communication, as the device can directly look up the appropriate channel based on the detected region, thereby reducing operational complexity

AI summary
The disclosure provides a method of automatically selecting a legal range communication channel within an unlicensed spectrum for a mobile electronic device and a mobile electronic device using the same method. In one of the exemplary embodiments, the mobile electronic device would determine a geographical region information in which the mobile electronic device is located; determine a legal range of communication channels within an unlicensed spectrum according to the geographical region information; and select a communication channel from the legal range of communication channels for a communication through a first wireless interface.
