Network-Assisted UE Power Saving for Emergency Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User Equipment (UE) experiences rapid power depletion due to concurrent execution of multiple services and applications, leading to frequent battery recharging needs and potential interruption of essential services, especially emergency services like healthcare and disaster notifications.
Innovation Solution
A network-assisted power saving mechanism where a core network entity receives battery level indications from the UE and modifies application configurations, enabling/disabling services and reducing signaling information based on predefined thresholds to conserve power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple services and applications are concurrently executed on the UE, then service functionality and versatility are improved, but power consumption increases rapidly
Solution Approach 1:
The patent implements dynamic service configuration where the network entity receives battery level indications from the UE and adjusts service configurations accordingly. When battery levels are high, more services are enabled; when battery levels are low, services are selectively disabled to conserve power. This dynamic adaptation resolves the contradiction by making service functionality variable rather than fixed.
Solution Approach 2:
The patent changes the operational parameters of services based on battery level thresholds. The network entity modifies service configurations (enabling/disabling services, adjusting signaling information) according to the battery level indications received from the UE. This parameter change approach allows the system to maintain versatility when power is abundant while reducing power consumption when battery levels are low.
2Use of energy by moving object
If battery level is reduced to support basic functionality, then power consumption is managed, but emergency services may become unavailable
Solution Approach 1:
The patent applies local quality by differentiating between critical and non-critical services. The network entity selectively disables non-essential services while maintaining essential emergency services even when battery levels are low. This localized approach ensures that power management measures are applied only where necessary, preserving emergency service availability while still achieving power conservation.
3Use of energy by moving object
If the UE frequently recharges the battery, then power depletion is managed, but service continuity and user convenience are reduced
Solution Approach 1:
The patent implements preliminary action by proactively managing service configurations based on battery level predictions and thresholds. The network entity receives battery level indications and adjusts service configurations before complete power depletion occurs. This preliminary management prevents service interruptions and reduces the need for frequent recharging, thereby maintaining service continuity and user convenience.

AI summary
Disclosed herein is an apparatus (108) configured to receive, from a User Equipment (UE) (102), a first indication corresponding to a first threshold battery level associated with the UE (102). Further, the apparatus (108) is configured to modify, based on the received first indication, one or more configurations associated with one or more applications or services of the UE (102) and reduce the corresponding signalling information. Further, the apparatus (108) is configured to receive, from the UE (102), a second indication corresponding to a second threshold battery level associated with the UE (102). Furthermore, the apparatus (108) is configured to selectively enable and disable the one or more applications or services and reduce the corresponding signalling information based on the received second indication.
