Mobile Terminal Communication Mode Switching for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication terminals consume excessive power during page scanning, shortening their runtime due to continuous communication mode settings.
Innovation Solution
A method that alters the communication mode of mobile communication terminals to switch between bidirectional, unidirectional, and non-connectable modes based on user input, reducing power consumption by eliminating unnecessary page scans in unidirectional mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile communication terminal performs page scan to receive request signals from external devices, then the terminal can establish communication connections, but the power consumption increases and runtime is shortened
Solution Approach 1:
The patent applies dynamics by making the communication mode changeable between bidirectional mode (with page scan) and unidirectional mode (without page scan). The system dynamically adjusts its behavior based on operational needs, allowing the terminal to switch between power-consuming and power-saving states rather than continuously performing page scans.
Solution Approach 2:
The patent changes the operational parameter of communication mode between two states: bidirectional mode where the terminal performs page scans to receive request signals, and unidirectional mode where the terminal does not perform page scans. This parameter change allows the system to optimize power consumption based on whether external communication is currently needed.
2Adaptability or versatility
If the communication mode is set to bidirectional mode, then the terminal can receive request signals from external devices, but the power consumption increases due to continuous page scanning
Solution Approach 1:
The system dynamically switches between bidirectional and unidirectional communication modes based on operational requirements. When external device connection is needed, it transitions to bidirectional mode; when not needed, it transitions to unidirectional mode to save power, thus making the system adaptable without continuous energy consumption.
Solution Approach 2:
The patent implements periodic evaluation of communication needs and switches between modes accordingly. Rather than continuously maintaining bidirectional mode with page scanning, the system periodically assesses whether external communication is required and adjusts its state, reducing overall power consumption while maintaining adaptability when needed.
3Ease of operation
If the mobile communication terminal continuously maintains communication mode setting, then it is ready for external communication, but the runtime is shortened due to increased power consumption
Solution Approach 1:
The system dynamically adjusts its communication readiness state. Instead of continuously maintaining bidirectional mode which drains battery and shortens runtime, the terminal transitions to unidirectional mode when external communication is not actively needed, thereby extending runtime while maintaining ease of operation when communication is required.
Solution Approach 2:
The communication mode selection is based on the terminal's own operational needs and external environment. The system self-adjusts between bidirectional and unidirectional modes according to whether it needs to receive external request signals, eliminating the need for continuous manual intervention while optimizing runtime through automatic power management.

AI summary
A method is disclosed that alters a communication mode in a mobile communication terminal. The method includes: if the mobile communication terminal receives a connection signal for an external device, determining whether the communication mode is set to a bidirectional mode; if the communication mode is not a bidirectional mode, determining whether the communication mode is set to a unidirectional mode; and if the communication mode is a unidirectional mode, paging with the external device. The mobile communication terminal can reduce its power consumption and thus extends its remaining run time.
