Remote Wireless Device Control via Text Message Command
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in locating and controlling misplaced mobile phones, especially when they are in silent mode or left in public spaces, leading to noise pollution and potential unauthorized calls.
Innovation Solution
A method and device that allow remote control of wireless communication devices using text messages, utilizing TP-User-Data or TP-Protocol-Identifier stored within the message to execute operations such as switching from silent to ringing mode or turning off the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the mobile phone is set to silent mode to avoid noise pollution, then the harmful noise effect is reduced, but the ability to locate the phone through ringtone is lost
Solution Approach 1:
The patent introduces text messages as an intermediary carrier to transmit control commands to the mobile phone. The message contains specific data (TP-User-Data or TP-Protocol-Identifier) that the phone's logic unit interprets to execute remote control operations, enabling location triggering without requiring the phone to be in ringing mode
2Ease of operation
If the mobile phone is left in public space without remote control capability, then the device can operate autonomously, but unauthorized calls and noise pollution occur
Solution Approach 1:
The patent enables preliminary remote actions to be taken before the user physically accesses the phone. By sending text messages with control commands ahead of time, the user can pre-configure the phone's state (mute, volume level, location triggering) so that when the phone is later picked up or left in public, it operates according to pre-set instructions rather than allowing unauthorized usage
Solution Approach 2:
The mobile phone's logic unit is designed to automatically interpret and execute commands from text messages without requiring human intervention. When a message containing TP-User-Data or TP-Protocol-Identifier data is received, the logic unit autonomously processes the command and executes the corresponding operation, enabling the phone to self-regulate its behavior based on remote instructions
3Difficulty of detecting and measuring
If traditional dialing method is used to locate a misplaced phone, then the phone can be located through ringtone, but the method is ineffective when the phone is in silent mode
Solution Approach 1:
The patent changes the operational parameter of phone location from passive ringtone generation to active location triggering through text message reception. Instead of relying on the phone being in ringing mode, the system sends a text message that triggers the phone to generate sound (ringtone or vibration) at the moment of receipt, making the location method effective regardless of the phone's previous mode setting
Data Source
AI summary
A method for remote controlling a wireless communication device by a message includes the following steps: the wireless communication device receives a message; and the wireless communication device executes a corresponding operation according to the data stored in the TP-User-Data (TP-UD) field or the data stored in the TP-Protocol-Identifier (TP-PID) field. A user can control the wireless communication device to perform functions like increasing volume or switching from a silent mode to a sound mode, or even switching the mobile phone off, through transmitting a text message to the mobile phone.
