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

VSEngineering 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

Engineering Contradiction:
Improvepower consumptionVSAvoidsignaling overhead
Core Design Contradiction:
Use of energy by moving objectVSLoss of information

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.

Inventive Principle:
Principle #10Preliminary action

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.

Inventive Principle:
Principle #23Feedback

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

Engineering Contradiction:
Improveadaptability to traffic profilesVSAvoidconfiguration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #10Preliminary action

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.

Inventive Principle:
Principle #24Intermediary (Mediator)
