Solution Overview

Problem

Current access control mechanisms in wireless communication systems, such as LTE, face challenges in managing network congestion and efficiently controlling terminal device access, leading to suboptimal user experience due to lack of flexibility and effectiveness in prioritizing access requests.

Innovation Solution

A method where a radio access network device sends access control information to terminal devices with a list of check items in a predetermined order, each containing target object information and result processing information, allowing devices to sequentially check and determine access based on matching attributes and statuses, with options for probability and prohibition durations, to flexibly manage access and alleviate congestion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional access control mechanisms (ACB, SSAC, ACDC) are used, then access control functionality is provided, but flexibility and effectiveness in prioritizing access requests are insufficient

Engineering Contradiction:
Improveaccess control flexibilityVSAvoidaccess control effectiveness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The access control check items are segmented into multiple independent check items, each with specific target object information and result processing information. This segmentation allows the terminal device to perform sequential checks with different priorities and conditions, enhancing flexibility in access control while maintaining effectiveness through structured evaluation

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The access control mechanism uses dynamic check items that can be configured with different target objects, result processing methods, and priorities. The system adapts to different access scenarios by dynamically selecting and evaluating appropriate check items in sequence, providing both flexibility and reliability

Inventive Principle:
Principle #15Dynamics

2Reliability

If multiple access control mechanisms are applied, then comprehensive access control is achieved, but check time increases

Engineering Contradiction:
Improveaccess control comprehensivenessVSAvoidaccess check time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The access control check items are pre-configured with target object information, result processing information, and priorities. The terminal device performs sequential checks starting from highest priority items, allowing preliminary evaluation of access requests against multiple criteria without requiring exhaustive checking of all possible conditions

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The sequential check mechanism allows the terminal device to skip lower priority check items once a decisive result is obtained from higher priority checks. This rushing through mechanism reduces overall check time while maintaining comprehensive access control evaluation

Inventive Principle:
Principle #21Skipping (Rushing through)
