Mobile Device Radio State Management Using Mobility Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices face battery life issues due to the need to constantly monitor and manage various short-range radio technologies like Wi-Fi and Bluetooth, which consume power when enabled, and users often leave them on unnecessarily, leading to inefficiency and safety concerns when driving.
Innovation Solution
Implementing a method to monitor device mobility states to automatically enable and disable short-range radios, such as Bluetooth, based on predetermined mobility thresholds and connection status, ensuring radios are only active when needed and quickly reconnected when the user is stationary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If short-range radios (Wi-Fi, Bluetooth) are kept enabled to detect available connections, then connection availability and responsiveness are improved, but battery life deteriorates due to increased power consumption
Solution Approach 1:
The patent implements dynamic radio state management where radios transition between enabled and disabled states based on real-time mobility detection. The system continuously monitors mobility state and automatically enables radios when the device is stationary (likely at destination) and disables them when moving, creating a dynamic adaptation to user needs rather than static on/off states
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring mobility state and using this information to control radio enablement. The mobility detection provides feedback about device movement status, which feeds back into the radio control logic to determine whether to maintain or change radio states, creating a closed-loop control system that optimizes power consumption based on actual usage conditions
2Use of energy by moving object
If users manually switch radios on only when needed, then battery life is improved, but user convenience deteriorates due to manual intervention requirements
Solution Approach 1:
The patent implements self-service automation where the system automatically manages radio enablement without user intervention. The mobility detection system autonomously determines when radios should be enabled or disabled based on device movement patterns, eliminating the need for users to manually switch radios on and off while optimizing battery life
3Ease of operation
If users leave radios enabled all the time to avoid manual switching, then connection responsiveness is improved, but battery life deteriorates and safety concerns arise during driving
Solution Approach 1:
The system dynamically adjusts radio states based on real-time mobility conditions rather than maintaining a static enabled state. By detecting device movement, the system can determine when the user is likely driving and automatically disable radios during motion, then re-enable them when stationary, providing both safety benefits and power savings while maintaining connection responsiveness when needed

AI summary
This disclosure is directed to a method, computer program product and mobile communication device configured for managing radio states in a mobile communication device using device mobility information. A mobility state is determined from the number of cell changes over a predefined period of time. If the mobility state transitions to medium or high, such as when the user is in a vehicle, a Bluetooth radio is enabled. If a connection to a Bluetooth-enabled device is available, a connection is established. When the connection is disconnected, a configurable timer is started. If the timer expires without re-establishing the connection or the mobility state transitioning to medium or high, the Bluetooth radio is disabled to reduce power consumption. According to an embodiment, a Wi-Fi radio may then enabled to establish a Wi-Fi connection. Various configurations of computer program products and mobile communication devices are also described.
