Solution Overview

Problem

Existing solutions for remotely controlling a lost mobile phone are either cumbersome, require specific hardware, or involve costly network modifications, failing to efficiently forward SMS messages or lock screens to ensure data security.

Innovation Solution

A server and method that allow remote control of a communications terminal through a network, using a receiving module, acquiring module, management and control instruction generating module, and push service module to execute commands such as SMS forwarding and screen locking without modifying existing network elements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If SIM card is inserted into SMS message monitor hardware to forward SMS messages, then SMS message forwarding is enabled, but device complexity increases and ease of operation deteriorates because users need to physically handle and insert SIM cards into external hardware

Engineering Contradiction:
ImproveSMS message forwarding capabilityVSAvoidUser operation convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical system of physically inserting SIM cards into external SMS monitoring hardware with an electronic/software-based solution. The terminal device itself performs SMS monitoring and forwarding through pre-installed software modules, eliminating the need for external hardware and manual SIM card manipulation. This substitution resolves the contradiction by maintaining SMS forwarding reliability while dramatically improving ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The terminal device performs SMS monitoring and forwarding functions autonomously through integrated software modules without requiring external hardware assistance. The device self-manages the SMS forwarding process by monitoring incoming messages and automatically forwarding them to designated contacts, eliminating the need for users to physically connect external devices or manipulate SIM cards between different hardware components.

Inventive Principle:
Principle #25Self-service

2Reliability

If security number is set in lost mobile phone for remote control, then remote control capability is enabled, but loss of time increases because users must access a separate security number mobile phone to send control commands

Engineering Contradiction:
ImproveRemote control capabilityVSAvoidTime to access control function
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent merges the remote control functionality directly into the terminal device itself through a control module that is always present and accessible. Instead of requiring a separate security number mobile phone, the terminal device integrates screen locking, SMS filtering, and other control functions that can be activated immediately through the device's own interface or pre-configured shortcuts, eliminating the time delay of accessing a separate device.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The terminal device performs preliminary configuration of control functions during normal operation, including pre-installing control modules, configuring security parameters, and setting up automatic response mechanisms. When the device is lost, these pre-configured functions can be activated immediately through simple user actions or automated protocols, eliminating the need to set up control capabilities at the moment of loss and reducing response time.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If integrated modification on SMS message gateway and SMS message center is performed to implement anti-thief function, then anti-thief capability is improved, but manufacturing precision deteriorates due to costly and complex network element modifications

Engineering Contradiction:
ImproveAnti-thief capabilityVSAvoidNetwork modification cost and complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces the complex mechanical/network infrastructure modification approach with a software-based solution implemented at the terminal device level. Instead of modifying SMS gateways and message centers in the network infrastructure, the terminal device itself performs anti-thief functions through integrated software modules that monitor SMS messages, detect suspicious activities, and execute protective actions locally, eliminating the need for expensive and complex network modifications.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The terminal device acts as an intermediary that performs anti-thief functions locally without requiring network infrastructure modifications. The device intercepts and processes SMS messages through its own software modules, filtering and analyzing message content to detect theft attempts, and executing protective actions independently. This intermediary approach maintains anti-thief capability while avoiding the complexity and cost of modifying network elements.

Inventive Principle:
Principle #24Intermediary (Mediator)
