Call History Display with Segmented State Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of mobile communication terminals face difficulty in determining the state of call reception/origination and success of call connection due to the sequential deletion of old information, making it hard to track call history effectively.
Innovation Solution
A method and apparatus that store and display call information in a mobile communication terminal, using a call count database to accumulate and display the number of call occurrences, with options to view detailed information, including the number of successful and missed calls, by implementing a controller and display module that manage call data and user inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If call information is stored sequentially and old information is deleted to make room for new calls, then the memory can accommodate a large number of calls, but the user cannot easily determine the state of call reception/origination and success of call connection
Solution Approach 1:
The patent segments call information into distinct categories (received calls, originated calls, missed calls, successful connections, failed connections) and displays them in separate groups. This segmentation allows the memory to store a large number of calls while maintaining ease of operation by enabling users to quickly identify call states through organized grouping rather than searching through sequential lists.
2Device complexity
If only the latest call information is memorized by deleting old information, then memory space is optimized, but the user loses historical call data context
Solution Approach 1:
The patent extracts and displays specific call state information (reception/origination state and connection success) as prominent features within the call list. By taking out these key state indicators and presenting them separately or alongside call records, the system maintains comprehensive historical data without increasing memory complexity, as the state information is integrated into the existing storage structure.
3Speed
If call information is displayed in sequential order, then the display is simple and fast, but the user cannot easily determine patterns in call reception/origination
Solution Approach 1:
The patent adds an organizational dimension to call display by grouping calls according to their state (received/originated) and connection outcome (successful/failed). This dimensional organization overlays the sequential display, allowing fast presentation while enabling users to detect patterns and states through the added categorical structure without sacrificing display speed.

AI summary
Disclosed is a method for controlling a communications device, and a communications device thereof, comprising displaying on a first window, for a plurality of call items, information of a counterpart communications device, a number of occurred calls with the counterpart communications device, and a call type including one of a received call type, a dialed call type, and a missed call type; and displaying at least one detailed item for a selected call item on a second window, upon user selection of the call item, wherein the at least one detailed item for each call of the number of occurred calls displayed on the second window includes a time point of the call occurrence or a time point of call connection.
