User Equipment Dormant Mode Battery Consumption Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smartphones and MTC terminals face significant battery consumption due to communication module activity, necessitating a method to minimize power usage, especially when data transmission is not necessary.
Innovation Solution
Implementing a dormant mode that suspends data transmission between the user equipment and network, allowing the communication module to conserve battery life by determining when to enter this mode and sending relevant messages to the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication module operates continuously to maintain data transmission capability, then communication reliability is improved, but battery consumption increases
Solution Approach 1:
The communication module dynamically transitions between active and dormant states based on traffic conditions. The system adjusts its operational state in real-time, switching to dormant mode during idle periods while maintaining the ability to quickly resume active communication when data transmission is required, thus balancing reliability and energy consumption
Solution Approach 2:
The system implements periodic monitoring of traffic patterns and uses sleep cycles during predetermined idle periods. By establishing regular intervals for checking data transmission needs and entering dormant mode during confirmed idle times, the system reduces average power consumption while maintaining communication reliability through periodic reactivation
2Use of energy by moving object
If the communication module enters dormant mode to reduce battery consumption, then energy efficiency is improved, but communication response time increases
Solution Approach 1:
The system performs preliminary assessment of traffic patterns and predicts idle periods before entering dormant mode. By anticipating when data transmission is unlikely to occur and proactively transitioning to dormant state, the system minimizes unnecessary active periods while ensuring quick response when actual transmission needs arise
Solution Approach 2:
The communication module autonomously manages its own dormant/active state transitions based on local traffic condition monitoring. The system self-determines when to enter or exit dormant mode without requiring external network commands, enabling faster local decision-making and reducing response time penalties associated with network coordination overhead
3Extent of automation
If dormant mode is implemented without network coordination, then device autonomy is improved, but network synchronization reliability deteriorates
Solution Approach 1:
The system implements feedback mechanisms where the UE monitors network conditions and adjusts its dormant mode operations accordingly. By continuously receiving network status information and adapting its sleep/wake schedule based on network responses and traffic patterns, the system maintains synchronization reliability while preserving device autonomy in making local decisions
Data Source
AI summary
Provided are a method and apparatus for dormant mode operation in a user equipment. During dormant mode, data transmission between the user equipment and network is suspended. For dormant mode operation, the user equipment determines whether to enter dormant mode, and sends, upon determining to enter dormant mode, a dormant mode entry message containing dormant mode time information to the network.
