Solution Overview

Problem

Conventional mobile networks face inefficiencies in power management as they struggle to scale with increasing numbers of user equipment (UEs) and machine-to-machine (MTC) devices, leading to strain in per-UE tailored power management and resource over-provisioning, especially with unpredictable mobility and transmission schedules.

Innovation Solution

A method where a third-party entity sets power management policies using lookup tables or thresholds, allowing UE grouping for centralized power management instructions, offloading processing from the network to improve flexibility and efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If per-UE tailored power management is implemented, then power management precision is improved, but network complexity and processing burden increase significantly

Engineering Contradiction:
Improvepower management precisionVSAvoidnetwork complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments UEs into different groups based on their power management characteristics and requirements. Each UE group is assigned specific power management parameters, allowing the network to manage power consumption in a tailored manner without having to individually configure each UE. This segmentation reduces network complexity while maintaining precision for each group.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a new parameter - UE group ID - that changes the state of power management from individual UE-based to group-based. By modifying this parameter, the system can switch between different power management granularities, reducing the processing burden on the network while still providing tailored power management through group-specific parameters.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If network resources are over-provisioned to accommodate unpredictable mobility and transmission schedules, then adaptability is improved, but resource utilization efficiency deteriorates

Engineering Contradiction:
Improvenetwork adaptabilityVSAvoidresource utilization efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements dynamic power management parameters that can be adjusted based on UE group characteristics and network conditions. Instead of static over-provisioning, the system dynamically allocates power management resources to UE groups based on their actual needs, improving both adaptability and resource utilization efficiency simultaneously.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent enables UEs to self-identify with appropriate UE groups based on their power management requirements. This self-service mechanism reduces the signaling overhead and processing burden on the network, allowing the system to maintain high adaptability without requiring extensive network resources for UE classification and management.

Inventive Principle:
Principle #25Self-service

3Device complexity

If fixed power management schemes are used, then device complexity is reduced, but adaptability to changing network conditions deteriorates

Engineering Contradiction:
Improvepower management complexityVSAvoidpower management adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal power management framework where UE groups can be assigned different power management parameters based on their requirements. The same basic mechanism serves multiple functions - it can handle both simple and complex power management scenarios, providing adaptability without increasing device complexity. The UE group mechanism acts as a universal interface that can accommodate various power management strategies.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A method for User Equipment (UE) power management in a wireless communication system is provided. A connection manager of the communication system receives a power management policy from a third party entity. The policy directs setting of a power management scheme according to status information of the UE. The third party entity is functionally separate from the UE and a network domain associated with the connection manager. Status information is received from the UE. A power management instruction is transmitted towards the UE to modify power management parameters stored in the UE
