Data Storage Medium Quiescent Mode Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
New technologies in data storage media for mobile communication systems result in higher leakage currents when transitioning to a quiescent mode, exceeding the maximum power consumption specifications defined by standards like ETSI TS 100 977 V8.3.0, which are critical for extending battery life and minimizing power usage.
Innovation Solution
Implementing a transmission delay for the last item of information during the operating mode to ensure that the data storage medium enters the quiescent mode immediately after information transmission, thereby avoiding excessive power consumption by disconnecting unnecessary components from the supply voltage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If new technologies are used in data storage media, then manufacturing precision and performance are improved, but leakage current increases causing excessive power consumption in quiescent mode
Solution Approach 1:
The patent applies preliminary action by delaying the transmission of the last information item until the quiescent mode has been fully activated and power consumption is within acceptable limits. This ensures that the transition to low-power mode is completed before final data transmission occurs, preventing excessive power consumption while maintaining new technology performance benefits
2Loss of energy
If circuit parts are disconnected from supply voltage to reduce power consumption, then power saving is improved, but transmission of the last information item may be interrupted
Solution Approach 1:
The system performs preliminary action by queuing the last information item for transmission and only transmitting it after confirming that quiescent mode activation will not interrupt the transmission. This ensures reliable information delivery while achieving power saving goals through controlled mode transitions
3Loss of energy
If the data storage medium enters quiescent mode immediately after information transmission, then power consumption is reduced, but the last information item may be transmitted during high-power operation exceeding standards
Solution Approach 1:
The patent applies preliminary action by delaying the transmission of the last information item until the quiescent mode has been fully activated and power consumption is within acceptable limits. This ensures that the transition to low-power mode is completed before final data transmission occurs, preventing excessive power consumption while maintaining data integrity

AI summary
A method for operating a data storage medium when changing from an operating mode to a directly subsequent power-saving quiescent mode, where the operating mode effects a transmission delay for the last item of information which is to be transmitted, so that immediately after the last item of information which is to be transmitted has been transmitted the quiescent mode is activated and the maximum permissible power consumption is observed.
