Solution Overview

Problem

Conventional resource management methods in wireless communication systems are inadequate for handling scenarios where a user equipment (UE) interacts with two or more radio access points, as they are designed for single-point interactions, and fail to manage resources effectively across multiple access points, particularly in diversified wireless communication systems.

Innovation Solution

A radio resource management method that involves receiving measurement reports from terminals, selecting and requesting service from another radio access point based on Handover Restriction Lists (HRL), and managing resources using Resource Restriction Lists (RRL) to control interactions and resource allocation across multiple radio access points.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional resource management methods are used for single-point interactions, then resource management is simple, but resource management becomes inadequate when UE interacts with multiple radio access points

Engineering Contradiction:
Improveresource management capabilityVSAvoidmanagement system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments resource management into two distinct components: Handover Restriction Lists (HRL) for mobility management and Resource Restriction Lists (RRL) for resource management. This segmentation allows each component to handle specific aspects independently, enabling multi-access point resource management without creating a completely complex new system. The HRL manages which access points a UE can move to, while the RRL manages resource allocation across multiple access points, resolving the contradiction by adding adaptability through structured division of management functions.

Inventive Principle:
Principle #1Segmentation

2Productivity

If resource restriction lists are implemented to manage multiple access points, then resource utilization improves, but system complexity increases

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidresource management structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The Resource Restriction List (RRL) is designed as a universal mechanism that can be applied across multiple radio access points and different UE contexts. Rather than creating separate management structures for each access point or scenario, the RRL provides a multi-functional framework that handles resource allocation, restriction, and coordination uniformly. This universal approach improves resource utilization efficiency across the entire network while avoiding the proliferation of separate complex management systems for each access point.

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

3Measurement precision

If mobility management and resource management are handled separately, then resource management precision improves, but processing overhead increases

Engineering Contradiction:
Improveresource management precisionVSAvoidprocessing overhead
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent introduces the Resource Restriction List (RRL) as an intermediary structure that bridges mobility management and resource management. The RRL receives inputs from both HRL (mobility aspect) and resource allocation requirements, then coordinates resource allocation across multiple access points based on both mobility constraints and resource availability. This intermediary approach enables precise resource management by considering both mobility and resource factors simultaneously, while avoiding the need for separate complex processing chains that would increase overhead.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A resource management method and apparatus allows or restricts use of some or all of the resources of entities of a wireless communication system. A radio resource management method of a radio access point includes receiving a measurement report from a terminal, selecting another radio access point for serving the terminal in cooperation with the serving radio access point based on the measurement report and a Handover Restriction List (HRL), and transmitting a request for serving the terminal to the selected another radio access point.
