Mobile Device Call Log Line Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile device users face challenges in managing and tracking outgoing calls across multiple communication lines, as existing systems often default to a single active line, making it difficult to select and log calls on specific lines, especially for business and personal use scenarios.
Innovation Solution
A system and method for a mobile device that provides a dynamic display for identifying and selecting multiple communication lines for outgoing calls, along with a call log feature that tracks call activity by line, allowing users to easily switch between lines and log calls on different communication lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single active line is used for outgoing calls, then the device operation is simple, but the user cannot track calls by specific communication line
Solution Approach 1:
The call log is segmented into separate entries for each communication line, allowing users to track calls by line while maintaining a unified interface. Each line has its own call log section that can be accessed independently, resolving the contradiction between simplicity and detailed tracking.
Solution Approach 2:
The system adds a dimensional layer by organizing call logs according to communication lines without changing the basic call interface. Users can view calls grouped by line (first dimension) or by individual entries (second dimension), providing both simplicity and detailed information access.
2Adaptability or versatility
If multiple communication lines are supported, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The call log interface is designed to be universal, handling multiple communication lines through a single unified structure. The same interface used for single-line devices also supports multi-line devices, eliminating the need for separate complex interfaces for each line.
Solution Approach 2:
The system pre-organizes communication lines into a selectable structure before calls are made. Users can pre-select which line to use for outgoing calls, and the call log automatically groups entries by line, reducing the complexity of line management during actual usage.
3Loss of information
If call log data is organized by communication line, then the information accessibility is improved, but the display complexity increases
Solution Approach 1:
The call log display is segmented into line-based sections, with each section containing calls for a specific communication line. This segmentation allows easy filtering and access by line while maintaining a consistent, predictable display structure that does not significantly increase complexity.
Solution Approach 2:
The system provides detailed line-specific call information only when needed, rather than displaying all call details simultaneously. Users can access partial information (summary by line) or complete information (individual call entries) based on their needs, reducing display complexity while maintaining information accessibility.

AI summary
A system and method for providing on a mobile device a call log for identifying call activity associated with a plurality of communication lines. The method comprises: displaying a call screen on a display of the mobile device; displaying call log data within a call log field on the display; wherein the call log data comprises at least one call entry. Each call entry comprises: call data corresponding to a third party telephone number, and a line indicia, wherein each line indicia uniquely corresponds to one of the communication lines.
