Power Saving Profile for Discontinuous Reception Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current discontinuous reception configuration mechanisms in communication systems are not responsive to the needs and activities of user equipment, leading to inefficient power management and increased signaling overhead.
Innovation Solution
A method to determine a power saving profile based on the state of the user equipment, including user settings, activity levels, applications, traffic characteristics, and sensor parameters, which is then signaled to the serving network element to adjust discontinuous reception parameters for improved power management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If discontinuous reception configuration is made more responsive to user equipment needs and activities, then power consumption is optimized and battery life is improved, but signaling overhead between user equipment and network element increases
Solution Approach 1:
The network element receives and stores power saving profile information from the user equipment in advance, before actual discontinuous reception configuration is needed. This preliminary action allows the network to quickly adapt DRX parameters without requiring extensive real-time signaling exchanges, thus optimizing power consumption while minimizing signaling overhead.
Solution Approach 2:
The user equipment provides feedback to the network element about its power saving requirements, activities, and applications through the power saving profile. This feedback mechanism enables the network to configure appropriate DRX parameters that match the UE's actual needs, improving power efficiency without requiring continuous signaling to adjust configurations.
2Adaptability or versatility
If discontinuous reception parameters are adjusted frequently to match user equipment activity levels, then adaptability to time-varying traffic profiles is improved, but device complexity increases
Solution Approach 1:
The network element performs the complex task of receiving, analyzing, and storing power saving profile information in advance. This preliminary processing of configuration data reduces the complexity burden on the user equipment during actual operation, while still enabling highly adaptable DRX parameter adjustment based on time-varying traffic profiles.
Solution Approach 2:
The power saving profile acts as an intermediary data structure that captures complex user equipment characteristics, activities, and preferences. This intermediary representation simplifies the interaction between the network element and user equipment, allowing flexible DRX configuration without requiring complex real-time negotiations or device-side processing.

AI summary
An apparatus, method and system for the management of reception parameters in a communication system. In one embodiment, the apparatus includes at least one processor, and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to determine a power saving profile based on a state of the apparatus disassociated from ongoing traffic monitoring at a radio layer, and provide the power savingprofile via a signaling message to a serving network element.
