Terminal Non-Connecting Call List Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing terminal devices lack a function to separately manage and reoriginate calls that fail to connect, requiring users to search through extensive call records, and struggle with temporary storage and retrieval of telephone numbers, especially when not intended for use with directory applications.
Innovation Solution
A terminal apparatus and method that includes a memory for storing non-connecting telephone numbers in a temporary list and a controller to manage and distinguish these numbers, allowing convenient reorigination of calls and notification features for failed connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a terminal stores all call records in a unified list, then the storage structure is simple, but it becomes difficult to search for and reoriginate failed calls efficiently
Solution Approach 1:
The patent divides call records into separate categories: a failed call list for calls that failed to connect and a normal call list for successful calls. This segmentation allows users to easily access and reoriginate failed calls without searching through all call records, while maintaining manageable complexity through organized storage structures.
2Adaptability or versatility
If a terminal provides temporary storage for telephone numbers, then it can store numbers not in the directory, but it becomes difficult to manage and retrieve these temporary numbers
Solution Approach 1:
The patent creates a separate temporary call list that is distinct from both the failed call list and the directory. This segmentation allows the terminal to store temporary numbers with adaptability while enabling easy retrieval through a dedicated interface, preventing mixing with other call records.
3Productivity
If a terminal stores detailed information about failed calls, then it can provide better reorigination functionality, but it increases the complexity of data management
Solution Approach 1:
The patent stores detailed information (telephone number, failure reason, timestamp) specifically in the failed call list, separating this detailed data management from normal call records. This segmentation enables efficient reorigination by providing all necessary information in one place while keeping the overall system complexity manageable through organized data structures.
Solution Approach 2:
The patent extracts failed call information into a separate dedicated list, removing the burden of managing detailed failure data from the general call record system. This extraction allows for specialized handling of failed calls with improved reorigination efficiency while maintaining simplicity in the overall call management system.

AI summary
An apparatus and a method manage a telephone number in a terminal, which can separately manage telephone numbers, a call to each of which an attempt to originate has been made and to each of which the call has failed to be connected, and then enable a convenient attempt to re-originate a call to the telephone number. The apparatus includes: a memory including a temporary list which stores a non-connecting telephone number, to which a call has been originated and has failed to be connected; and a controller for performing a control operation so as to store a particular telephone number in the temporary list as the non-connecting telephone number, when an attempt to originate a call to the particular telephone number is made and the call fails to be connected to the particular telephone number.
