Mobile Terminal Testing Apparatus Frequency Band Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Creating scenarios for mobile communication terminal testing involving Long Term Evolution (LTE) base stations with overlapping frequency bands is challenging due to the difficulty in identifying and setting the correct multi-frequency band indicator (MFBI) settings, making it hard to perform effective testing.
Innovation Solution
A mobile terminal testing apparatus that simulates a base station, displaying the relationship between the selected frequency band and available frequency bands on a frequency axis, allowing visual identification of overlapping bands and easy setting of MFBI, using a pseudo-base station unit, display unit, and control unit to show positional relationships and differences between selected and available frequency bands.

Engineering Contradiction Analysis
1Ease of operation
If a scenario for the base station that uses the MFBI is created, then the mobile communication terminal can know in which band a base station can perform communication, but the frequency band that is used by the base station for communication has to be designated for a portion in which the bands overlap, and because the frequency band differs with a band, the portion in which the bands overlap is difficult to know and a setting is not easy to perform
Solution Approach 1:
The patent transforms the abstract frequency band setting problem into a visual spatial representation on a frequency axis. By displaying frequency bands as graphical elements positioned along a frequency axis, the system converts complex numerical frequency values into intuitive visual positions, making it easy to identify overlapping portions and set MFBI parameters without manual calculation or complex configuration.
Solution Approach 2:
The patent uses color coding to differentiate between various frequency band states and types. Different colors represent different band configurations, overlapping regions, and selection states, enabling operators to quickly understand the frequency band relationships and make accurate MFBI settings through visual cues rather than interpreting numerical data.
2Adaptability or versatility
If multiple frequency bands are used for communication, then convenience is improved, but the portion in which the bands overlap is difficult to know and setting is not easy to perform
Solution Approach 1:
The patent adds a visual dimension to frequency band representation by displaying multiple bands as graphical elements along a frequency axis. This transformation makes the overlapping portions of multiple bands immediately visible through spatial intersection, eliminating the difficulty of identifying overlap regions when using multiple frequency bands for communication.
Solution Approach 2:
The patent creates visual copies or representations of actual frequency bands on the display interface. These graphical representations mirror the real frequency band characteristics and relationships, allowing operators to visually inspect and understand overlapping regions without needing to perform complex frequency calculations or refer to technical documentation.

AI summary
Provided is a mobile terminal testing apparatus capable of easily performing testing using a MFBI. The mobile terminal testing apparatus includes a display unit 12, and a control unit 14 that displays on the display unit 12 an image indicating a position on a frequency axis, of a selection frequency band that is selected as a frequency band which is used by a pseudo-base station unit, and an image indicating a position on the frequency axis, of an available frequency band that is able to be set as the MFBI with which the selection frequency band is overlapping, in such a manner that a positional relationship between both of the images is identifiable.
