Solution Overview

Problem

Wireless communication terminals face challenges in reducing power consumption during sleep states, as maintaining a wireless communication connection consumes power due to transmission of control packets even when data transmission is not required.

Innovation Solution

A wireless communication terminal with a communication control section that disconnects and reconnects the communication connection based on given conditions, allowing for a communication interrupted state to conserve power while maintaining application program functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the wireless communication connection is maintained during sleep state, then the communication connection continuity is preserved, but power consumption increases due to transmission of control packets

Engineering Contradiction:
Improvecommunication connection continuityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The terminal performs preliminary actions by establishing the communication connection before entering sleep state, and prepares to reconnect based on predicted data arrival. The connection is maintained only when data transmission is anticipated, avoiding unnecessary power consumption during periods when no data is expected.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The communication connection state is made dynamic rather than static. The terminal adaptively switches between connected and disconnected states based on real-time conditions such as data arrival predictions and application requirements. This dynamic adjustment allows the system to optimize between connection continuity and power consumption.

Inventive Principle:
Principle #15Dynamics

2Use of energy by moving object

If the wireless communication connection is disconnected during sleep state, then power consumption is reduced, but the application program that requires continuation of communication connection cannot operate normally

Engineering Contradiction:
Improvepower consumptionVSAvoidapplication program operation
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The system performs preliminary assessment of application requirements before disconnecting. By predicting whether data will arrive and whether the application needs continuous connection, the terminal can make informed decisions about disconnection timing, ensuring applications that require continuity are not adversely affected.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The terminal implements feedback mechanisms by monitoring data arrival patterns and application behavior. This feedback allows the system to learn from past interactions and improve its prediction accuracy, enabling smarter decisions about when to disconnect and when to maintain connections, thus balancing power savings with application functionality.

Inventive Principle:
Principle #23Feedback

3Reliability

If the communication connection is frequently re-established, then the application program can resume data transmission, but the time required for reconnection increases the delay

Engineering Contradiction:
Improvedata transmission resumptionVSAvoidreconnection delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Connection parameters and configuration information are prepared in advance during the disconnected state. When reconnection is needed, the terminal can quickly re-establish the connection using pre-configured parameters, significantly reducing the reconnection time compared to establishing a connection from scratch.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains connection state information and configuration data in memory during the disconnected period. This cushioning of connection-related data ensures that when reconnection is required, the terminal can rapidly restore the connection without experiencing significant delays, as the essential connection framework is already prepared.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

Provided is a wireless communication terminal that allows a wireless communication connection to be disconnected even when an application program that requires continuation of the communication connection is being executed. The wireless communication terminal transmits data to a communication target in response to a transmission processing request from an application execution section for executing the application program. The wireless communication terminal is configured to: establish the wireless communication connection to the communication target; disconnect, based on a given condition, the wireless communication connection to the communication target to cause a shift to a communication interrupted state; re-establish the wireless communication connection to the communication target when the transmission processing request is received in the communication interrupted state from the application executionsection;and transmit, to the communication target, the data relating to the transmission processing request after the re-establishment of the wireless communication connection.
