Wireless Device Dormancy Override Mechanism

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wireless devices experience rapid battery drain and unavailability for incoming calls due to prolonged radio module active states, caused by carrier-configured timeouts that prevent quick reentry into dormant state, leading to 25% active time during business hours.

Innovation Solution

A power management mechanism that uses a timer to override network timeouts, forcing the radio module into a dormant state after a predetermined interval (e.g., 5 seconds) after data transmission or receipt, allowing quicker state transitions and conserving battery life.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If the radio module remains in the active state to ensure quick reentry capability, then network responsiveness is improved, but battery drain increases and call availability decreases

Engineering Contradiction:

Improveradio module reentry speedVSAvoidbattery consumption

Core Design Contradiction:

SpeedVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic state management by introducing multiple dormant states (first dormant state with shorter timeout, second dormant state with longer timeout) and actively transitioning between them based on network conditions and power requirements. The system dynamically adjusts the radio module's timeout behavior rather than using a fixed state, allowing optimization between power consumption and reentry speed based on current operational needs

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the timeout parameter from a fixed carrier-configured value to a variable that can be overridden by the wireless device. By implementing configurable timeout values (e.g., 10 seconds, 20 seconds, or custom durations) and allowing the device to override network timeouts, the system can adjust the radio module's active state duration to balance power consumption with reentry capability

Inventive Principle:

Principle #35Parameter changes

2Loss of energy

If the radio module transitions quickly to dormant state to conserve battery, then power efficiency is improved, but network responsiveness deteriorates

Engineering Contradiction:

Improvebattery drainVSAvoidnetwork responsiveness

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The system dynamically selects between different dormant states and timeout configurations based on current power requirements and network conditions. Rather than always transitioning to the deepest dormant state, the system can maintain the radio module in lighter dormant states when quick reentry is needed, creating a dynamic balance between power conservation and network responsiveness

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements preliminary actions by pre-configuring multiple dormant states with different timeout characteristics before needing to transition. The system can prepare the radio module for potential quick reentry by maintaining it in a first dormant state with shorter timeout, rather than always forcing transition to the second dormant state with longer timeout

Inventive Principle:

Principle #10Preliminary action

3Reliability

If carrier-configured timeouts are enforced to maintain network connectivity, then network resource allocation is improved, but device power efficiency deteriorates

Engineering Contradiction:

Improvenetwork connectivityVSAvoidbattery consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent inverts the traditional control model by allowing the wireless device to override the carrier-configured timeouts rather than the carrier strictly enforcing them. The device can set its own timeout values and force transitions to dormant states even when the network would prefer the radio remain active, effectively reversing who controls the timeout parameter

Inventive Principle:

Principle #13The other way round (Inversion)

4Reliability

If the radio module stays active for extended periods, then incoming call reception is improved, but battery life deteriorates

Engineering Contradiction:

Improvecall reception availabilityVSAvoidbattery life

Core Design Contradiction:

ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The system dynamically manages the radio module's active state duration by implementing configurable timeouts and multiple dormant states. Rather than keeping the radio continuously active, the system can transition to appropriate dormant states while maintaining the ability to quickly react to incoming calls through the overridden timeout mechanism

Inventive Principle:

Principle #15Dynamics

AI summary

A wireless device is disclosed. The wireless device includes a radio module and an application. The radio module is used to communicate data on a wireless network. The application is used to facilitate the transition of the radio module from an active state to a dormant state. This transition occurs whenever data has not been communicated at the radio module for a predetermined time interval.
