Application-Aware Cellular Modem Control for Longer Battery Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face challenges in extending battery life due to high power consumption, particularly in advanced cellular systems like LTE and 5G NR, which support high-density mobile broadband and diverse applications.
Innovation Solution
Implementing application-aware cellular radio activation/deactivation mechanisms in devices like smartphones and tablets, where the cellular modem is disabled in power-saving modes and activated based on application inputs such as status, category, AI assistant status, network assertions, and proximity information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cellular modem is kept active to support diverse applications and high-density mobile broadband, then network connectivity and application performance are improved, but power consumption increases and battery life decreases
Solution Approach 1:
The system performs preliminary assessment of application requirements before activating the cellular modem. The network connections manager evaluates application inputs, category, and state to determine whether cellular connectivity is needed, activating the modem only when necessary rather than keeping it continuously active.
Solution Approach 2:
The cellular modem transitions between active and inactive states dynamically based on application needs. The system adapts the modem's operational state in real-time by monitoring application inputs and determining the appropriate connectivity state, rather than maintaining a fixed active state.
2Use of energy by moving object
If the cellular modem is disabled in power-saving mode, then power consumption is reduced and battery life is extended, but network connectivity is lost and application functionality is limited
Solution Approach 1:
The system continuously monitors application inputs, category, and state to determine when cellular connectivity is required. This feedback mechanism allows the system to activate the cellular modem when application functionality demands it, ensuring that power-saving mode does not permanently limit application capabilities.
Solution Approach 2:
The network connections manager autonomously manages the cellular modem's activation and deactivation based on application requirements. The system self-adjusts connectivity state without requiring manual user intervention, balancing power consumption with application functionality automatically.
3Adaptability or versatility
If the cellular modem is activated based on multiple application inputs and parameters, then application-specific connectivity needs are met, but system complexity increases
Solution Approach 1:
The network connections manager serves multiple functions: it receives application inputs, determines application category, assesses connectivity needs, and controls cellular modem activation. This multi-functional approach consolidates complexity into a single management component rather than requiring separate systems for each function.

AI summary
Apparatuses, systems, and methods for application aware cellular radio activation/deactivation, e.g., in 5G NR systems and beyond. The UE may receive, while operating in a power savings mode in which a cellular modem of the UE is disabled, inputs associated with an application of the UE. The UE may determine, based on the inputs, to activate the cellular modem to support the application of the UE. The inputs may include an indication of an application state or status, an indication of an application category, an indication of a state or status of an AI assistant of the UE, an indication of whether an application is a session application, an indication of network assertions, an indication of proximity information, an indication of a WiFi state or a WiFi status, and/or indications associated with one or more timers.
