Communication Device Call History Memory Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile phones lack the ability to provide customized information and mnemonics for callers, especially for non-registered phone numbers, leading to memory wastage and limited memory allocation for phonebooks.
Innovation Solution
A communication device and method that stores and displays call history information, allowing users to associate additional information with callers, even if their numbers are not registered in the phonebook, by extracting and displaying past interaction data during calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If standard register names are automatically assigned to phone numbers, then memory resources are utilized to store phonebook entries, but memory space is wasted and limited memory allocation prevents new phone number registration
Solution Approach 1:
The patent divides the information storage into two separate segments: the phonebook (for registered contacts) and call history (for all callers). This segmentation allows the system to store call history information without consuming phonebook memory resources, thereby resolving the contradiction between storing caller information and preserving memory space.
Solution Approach 2:
The patent extracts the functionality of storing caller information from the phonebook system and places it in a separate call history database. This extraction allows the system to maintain caller information without requiring phonebook registration, thus avoiding memory waste while preserving phonebook capacity for actual contacts.
2Loss of information
If phone numbers are registered in the phonebook to access caller information, then customized information can be displayed, but memory allocation is limited and new numbers cannot be registered when memory is deficient
Solution Approach 1:
The patent makes the call history database serve multiple functions: it stores information for registered phonebook contacts and simultaneously stores information for unregistered callers. This multi-functionality allows the system to provide caller information without requiring phonebook registration, thus resolving the contradiction between information availability and memory allocation.
Solution Approach 2:
The patent introduces call history as an intermediary storage mechanism between the phonebook and the display system. When a caller's information is needed, the system first checks the call history database before accessing the phonebook, allowing unregistered callers to be displayed without consuming phonebook memory.
3Ease of operation
If the phonebook stores all caller information, then users can access customized caller details, but the device complexity and memory requirements increase
Solution Approach 1:
The patent performs preliminary storage of caller information in the call history database during and after calls. This preliminary action ensures that caller information is already captured and organized before it needs to be displayed, allowing quick access without requiring complex real-time processing or phonebook registration for every caller.
Data Source
AI summary
A system and method for selecting callers on a communication device is disclosed. When a call is received from a caller, call history data are obtained from a call history database, and presented on a display. A user may then decide based on the call history whether to receive the call.
