Solution Overview

Problem

Wireless communication networks face inefficiencies when user equipment (UE) devices establish multiple concurrent Radio Access Technologies (RATs) due to limited resources, leading to suboptimal network performance.

Innovation Solution

UE devices dynamically adjust the number and type of RATs by concurrently using multiple RATs for improved throughput and then pruning unnecessary links based on duty cycle and throughput estimation to optimize network performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple concurrent RATs are used, then data throughput is improved, but device complexity and resource consumption increase

Engineering Contradiction:
Improvedata throughputVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system dynamically adjusts the number of concurrent RATs based on real-time network conditions, UE mobility state, and traffic requirements. The network entity monitors parameters such as signal quality, throughput, and UE speed, and adaptively configures whether to maintain multiple RAT connections or prune to a single RAT, thereby optimizing the balance between productivity and device complexity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes operational parameters including the number of active RATs, connection priorities, and resource allocation based on measured network conditions. By monitoring parameters like reference signal received power (RSRP), signal-to-noise ratio (SNR), and UE mobility indicators, the system adjusts configuration parameters to achieve optimal throughput while managing complexity

Inventive Principle:
Principle #35Parameter changes

2Reliability

If multiple concurrent RATs are maintained, then network reliability is improved, but power consumption increases

Engineering Contradiction:
Improvenetwork reliabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system dynamically switches between multi-RAT and single-RAT modes based on real-time assessment of network conditions and reliability requirements. When network conditions are stable and single RAT provides sufficient performance, the system prunes connections to conserve power. When conditions deteriorate or high reliability is required, multiple RATs are re-established

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The UE device autonomously monitors its own power consumption, processing capabilities, and network performance metrics to determine when to maintain or prune RAT connections. The device self-adjusts its connection strategy without requiring continuous network control signaling, thereby reducing overall power consumption while maintaining reliability

Inventive Principle:
Principle #25Self-service

3Speed

If multiple concurrent RATs are used, then data transmission speed is improved, but computational resource utilization increases

Engineering Contradiction:
Improvedata transmission speedVSAvoidcomputational resource utilization
Core Design Contradiction:
SpeedVSPower

Solution Approach 1:

The system dynamically adjusts computational resource allocation based on the number of active RATs and current processing load. When multiple RATs are active, the network entity and UE coordinate to optimize processing schedules, prioritize critical functions, and prune less important connections when computational capacity is constrained, thereby maintaining high data transmission speed while managing computational resource utilization

Inventive Principle:
Principle #15Dynamics
