Solution Overview

Problem

Current wireless communication systems face challenges in managing congestion and efficiently allocating radio resources, particularly in next-generation networks that require high data transfer rates, low latency, and energy efficiency, as existing access control mechanisms do not adequately account for the diverse characteristics of user equipment (UE) and traffic patterns.

Innovation Solution

A method for controlling access to a network by a UE that involves receiving a skip condition for access barring checks, determining if the UE satisfies this condition, and skipping the access barring check operation if applicable, allowing the UE to access the network without performing the check, thereby optimizing radio resource allocation across different radio access technologies and frequency bands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If access barring check operations are performed for all UEs, then network congestion can be controlled, but access delay and resource utilization deteriorate for UEs supporting multiple radio access technologies

Engineering Contradiction:
Improvenetwork congestion controlVSAvoidaccess delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies local quality by differentiating access control treatment based on UE capabilities. UEs supporting multiple radio access technologies (EN-DC, MR-DC, LAA, LWA, NR) receive optimized access control with skip conditions, while other UEs follow standard procedures. This localized differentiation resolves the contradiction by reducing access delay for capable UEs without compromising overall network congestion control.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent introduces dynamic access control through skip conditions that adapt to UE capabilities and network state. The network configures specific skip conditions (e.g., supporting EN-DC, MR-DC, LAA, LWA, or NR) that dynamically determine whether a UE can skip access barring checks. This dynamic approach allows the system to optimize access delay for multi-RAT UEs while maintaining congestion control through conditional skipping rather than universal skipping.

Inventive Principle:
Principle #15Dynamics

2Productivity

If access barring checks are skipped for multi-RAT UEs, then resource utilization improves, but network congestion control capability deteriorates

Engineering Contradiction:
Improveresource utilizationVSAvoidcongestion control capability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent changes the parameter of access control by introducing skip conditions based on UE capability parameters. Instead of uniform access barring, the system evaluates specific parameters (support for EN-DC, MR-DC, LAA, LWA, NR) to determine whether skipping is appropriate. This parameter-based differentiation improves resource utilization for capable UEs while maintaining congestion control through selective application of skip conditions rather than blanket skipping.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements feedback mechanisms where UEs report their capability parameters (support for various dual connectivity and aggregation technologies) to the network. The network uses this feedback to configure appropriate skip conditions, creating a closed-loop system that balances resource utilization improvement with congestion control capability. The feedback ensures that skipping decisions are informed by actual UE capabilities and network conditions.

Inventive Principle:
Principle #23Feedback

3Reliability

If standard access barring procedures are used for all UEs, then congestion control is maintained, but access efficiency deteriorates for UEs with advanced capabilities

Engineering Contradiction:
Improvecongestion controlVSAvoidaccess efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent segments the access control process into two distinct paths: standard access barring for UEs without advanced capabilities, and optimized access with skip conditions for UEs supporting multiple radio access technologies. This segmentation resolves the contradiction by allowing each UE type to follow the most appropriate procedure, maintaining congestion control for standard UEs while improving access efficiency for advanced UEs through capability-based differentiation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a universal access control framework that handles both standard and advanced UEs through a single mechanism. The skip condition evaluation serves multiple functions: it identifies capable UEs, determines appropriate access procedures, and maintains congestion control. This multi-functional approach improves access efficiency for advanced UEs without requiring separate systems, while preserving congestion control through the unified evaluation process.

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

AI summary

Disclosed are a method of accessing a network in a wireless communication system and an apparatus therefor. Specifically, a method of accessing a network by a user equipment (UE) in a wireless communication system may include receiving, from the network, a skip condition for an access barring check operation for a cell supported by a base station, determining whether the UE satisfies the skip condition for the access barring check operation, determining that access to the network on the cell has not been barred when the skip condition for the access barring check operation is satisfied, and performing the access to the network on the cell without performing the access barring check operation.
