Solution Overview

Problem

Current RRC configuration management in 5G networks is inflexible, allowing only one configuration to be stored and used across different states, leading to inefficiencies in state transitions and increased latency during connection resumptions.

Innovation Solution

Implementing a modular RRC configuration approach where multiple modules, each containing RRC parameters, can be stored and applied dynamically based on UE capabilities and network instructions, enabling flexible configuration management across various RRC states without the need for frequent reconfiguration procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If only one RRC configuration is stored and used across different states, then device complexity is reduced, but adaptability and network performance deteriorate

Engineering Contradiction:

ImproveRRC configuration management complexityVSAvoidRRC configuration adaptability across states

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The RRC configuration is segmented into multiple independent modules, each optimized for specific RRC states (idle, inactive, connected). The network can selectively store and apply appropriate configuration modules based on the current state, enabling state-specific optimization without managing a single monolithic configuration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system transitions from a static single configuration to a dynamic multi-module configuration system. The network can flexibly select, store, and apply different configuration modules as the UE transitions between RRC states, allowing the configuration to adapt dynamically to current operational requirements.

Inventive Principle:

Principle #15Dynamics

2Loss of energy

If a single RRC configuration is used for all states, then signaling overhead is reduced, but state transition latency increases

Engineering Contradiction:

Improvesignaling overheadVSAvoidconnection resumption latency

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

Multiple RRC configuration modules are pre-configured and stored in the network for different RRC states before state transitions occur. When the UE transitions between states, the network can immediately apply the pre-stored appropriate configuration module, eliminating the need for time-consuming reconfiguration procedures and reducing connection resumption latency.

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If multiple RRC configuration modules are stored and applied dynamically, then adaptability and network performance improve, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The RRC configuration system is designed with universal multi-functionality, where a single RRC entity manages multiple configuration modules that can serve different RRC states. This universal approach allows the same RRC infrastructure to handle various configurations without requiring separate management systems for each state.

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Speed

If multiple RRC configuration modules are stored and applied dynamically, then state transition speed improves, but signaling overhead increases
