Communication Authentication Power-State Switching for Timely Login
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication apparatuses face challenges in dynamically switching their power state to efficiently manage authentication processes with external apparatuses, often resulting in incomplete authentication or increased power consumption.
Innovation Solution
A communication apparatus is designed with a shift unit that dynamically changes its power state based on the connection process with an external apparatus requiring authentication. The apparatus shifts from a normal power mode to a power saving mode, adjusting the CPU operating frequency accordingly, to optimize power usage during authentication processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the communication apparatus operates in a power saving mode with reduced CPU frequency, then power consumption is reduced, but authentication processing may not be completed within the required time
Solution Approach 1:
The communication apparatus dynamically adjusts its operating state based on the authentication process stage. The shift unit switches between a first state (normal operation) and a second state (power saving mode with reduced CPU frequency) depending on whether authentication is in progress. This dynamic adaptation allows the system to optimize power consumption during idle periods while ensuring timely authentication completion when required.
Solution Approach 2:
The invention changes the operating parameters (CPU frequency, power mode) based on the authentication state. When authentication processing is detected to be in progress, the apparatus shifts from a power saving state with reduced CPU frequency to a normal operation state with full CPU frequency, ensuring authentication completes within required timeframes. This parameter adjustment resolves the contradiction between power saving and authentication timeliness.
2Use of energy by moving object
If the communication apparatus shifts to power saving mode during authentication processing, then power consumption is minimized, but authentication processing may fail or be incomplete
Solution Approach 1:
The authentication unit monitors the authentication processing state and provides feedback to the shift unit. When authentication processing is detected to be in progress, the system receives feedback indicating this state and automatically shifts from power saving mode to normal operation mode. This feedback mechanism ensures authentication reliability by preventing mode switching during critical authentication phases while maintaining power efficiency during idle periods.
Solution Approach 2:
The shift unit proactively shifts the apparatus from power saving mode to normal operation mode upon detecting the start of authentication processing, before authentication completes. This preliminary action ensures sufficient processing power is available throughout the authentication process, preventing authentication failures that could occur if the system remained in power saving mode during critical processing phases.
3Reliability
If the communication apparatus always operates in normal power mode, then authentication processing is completed reliably, but power consumption increases
Solution Approach 1:
The communication apparatus periodically monitors its operational state and switches between power saving mode and normal operation mode based on authentication processing requirements. During idle periods when no authentication is needed, the system operates in power saving mode to minimize power consumption. When authentication processing starts, the system transitions to normal operation mode to ensure reliable completion. This periodic state adjustment resolves the contradiction by achieving both power efficiency and authentication reliability.
Solution Approach 2:
The invention implements dynamic power management where the apparatus adapts its operating state in real-time based on authentication needs. The shift unit dynamically switches between first state (normal operation) and second state (power saving) depending on whether authentication processing is detected. This dynamic approach allows the system to minimize power consumption during idle periods while ensuring authentication reliability when required, eliminating the need to always operate in high-power normal mode.

AI summary
A communication apparatus comprises a shift unit configured to shift, based on a start of processing for connection between the communication apparatus and a predetermined external apparatus supporting authentication processing by a predetermined authentication method using an authentication server in a state in which the communication apparatus operates in a first state in which a processor of the communication apparatus operates at a first operating frequency, the state of the communication apparatus to a second state in which the processor of the communication apparatus operates at a second operating frequency higher than the first operating frequency; and an authentication unit configured to execute authentication by the predetermined authentication method via the predetermined external apparatus in the state in which the communication apparatus operates in the second state.
