Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face issues with accessing their portable terminals when they are misplaced or not carried, leading to potential theft of information and loss of service functionality, as existing solutions do not adequately address security and convenience for remote control.
Innovation Solution
A method and system for remotely controlling a portable terminal using a preset master terminal, enabling secure and user-friendly remote control of functions such as message forwarding and call barring, through authentication and message transmission via SMS or other networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control function is added to portable terminal, then user convenience is improved when terminal is misplaced or lost, but device complexity increases due to authentication and communication modules
Solution Approach 1:
The patent introduces a base station as an intermediary component that facilitates communication between the portable terminal and the external control system. The base station receives control messages from remote terminals and relays them to the target portable terminal, enabling remote control functionality without requiring complex direct communication protocols in the portable terminal itself. This mediator approach simplifies the overall system architecture while maintaining ease of operation.
2Object-affected harmful factors
If authentication mechanism is implemented for remote control, then security against malicious use is improved, but ease of operation deteriorates due to additional authentication steps
Solution Approach 1:
The patent implements preliminary authentication by pre-registering control terminals and storing their identification information in the portable terminal before remote control operations are needed. When a remote control message arrives, the terminal performs quick verification by checking if the controlling terminal's ID matches the pre-registered information. This preliminary setup reduces authentication complexity during actual remote control operations while maintaining strong security against unauthorized access.
3Reliability
If remote control capability is enabled, then functionality is maintained when terminal is lost, but loss of information risk increases if terminal is found by malicious user
Solution Approach 1:
The patent enables the portable terminal to autonomously perform security functions by automatically detecting whether it is in a lost state and independently executing predetermined countermeasures such as blocking communication or erasing data. The terminal uses its own resources and capabilities to protect itself without requiring constant external intervention, thereby maintaining functionality when needed while preventing information loss if the device is recovered by unauthorized persons.

AI summary
The present invention relates to a remote control of a portable terminal, and more particularly, to a method for remotely controlling functions of a portable terminal, and a system thereof. A method for remotely controlling a function of a portable terminal includes receiving a request for remote control of at least one function of the portable terminal, setting up the requested at least one function for remote control, determining whether an event corresponding to the set up function is generated and performing the set up function if the event is generated.
