Mobile Terminal Message Cleaning via Automated Rule-Based Deletion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The internal memory of mobile communication terminals becomes full due to accumulated messages, leading to inconvenience as new messages cannot be received, especially with frequent use of multimedia services.
Innovation Solution
A mobile communication terminal with a user interface, man-machine interface, cleaning management unit, timing trigger unit, and rule judgment unit that automatically cleans messages based on user-set frequencies and rules, using a timer to trigger cleaning operations without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If messages are retained in the internal memory for long-term storage, then message availability and user access are improved, but internal memory space becomes full and new messages cannot be received
Solution Approach 1:
The system performs preliminary actions by establishing cleaning rules and schedules in advance. The cleaning management unit is pre-configured with criteria for message deletion (e.g., time-based rules, sender-based rules, message type rules) and automatically executes cleanup operations according to predetermined schedules, preventing memory overflow before it occurs.
Solution Approach 2:
The message cleaning system operates autonomously without requiring continuous user intervention. The cleaning management unit automatically monitors message storage, evaluates messages against predefined rules, and executes deletion operations independently. The system serves itself by managing its own memory resources through automated cleaning cycles.
2Quantity of substance
If manual message cleaning is performed frequently to free up memory space, then internal memory availability is improved, but user operation complexity and time consumption increase
Solution Approach 1:
The system eliminates the need for manual user intervention by implementing an autonomous cleaning management unit. This unit automatically monitors message storage levels, evaluates messages against predefined cleaning rules, and executes deletion operations without requiring user action. The system performs self-maintenance, freeing users from repetitive manual cleaning tasks.
Solution Approach 2:
The cleaning management unit operates on periodic schedules rather than requiring continuous or frequent manual user intervention. Messages are cleaned at predetermined intervals (e.g., daily, weekly) based on user-defined settings, transforming a potentially time-consuming manual task into an automated periodic process that occurs in the background.
3Quantity of substance
If automated message cleaning is implemented, then memory space management is improved, but device complexity increases due to additional control units
Solution Approach 1:
The cleaning management unit is integrated with the existing message management system rather than being implemented as a completely separate external device. The timing trigger unit leverages the mobile terminal's existing timer functionality, and the rule judgment unit utilizes the processor's existing logical judgment capabilities. This merging approach minimizes additional hardware complexity while achieving automated cleaning functionality.
Solution Approach 2:
The cleaning management unit is designed with multi-functionality, serving multiple purposes within the message management system. It not only deletes messages but also monitors storage levels, evaluates various message attributes against multiple rule criteria, and coordinates with the timing trigger unit for scheduled operations. This universal design reduces the need for separate specialized components.

AI summary
This invention provides a mobile communication terminal and a message automatic cleaning method thereof. The mobile communication terminal comprises a user interface unit, a man machine interface and a message module interface, a cleaning management unit, a timing trigger unit and a rule judgment unit. The message automatic cleaning method of the mobile communication terminal comprises the following steps: step a, setting message directory automatic cleaning frequencies and rules in a rule judgment unit; step b, setting a waiting period of a timing trigger unit; step c, judging whether current information accords with the cleaning rule when the set waiting period ends, and deleting the message if the information accords with the rule. With the mobile communication terminal and the message automatic cleaning method thereof provided in the present invention, messages can be automatically deleted in accordance with the time and manner set by the user, so insufficiency of memory space caused by the messages being not cleaned by the user for a long time is avoided. Hence, it facilitates the user.
