Solution Overview
Problem
Cascaded small cell relay nodes in wireless networks often create bottlenecks due to equal backhaul bandwidth allocation, which can lead to inefficient resource utilization and poor quality of service, especially in areas with varying device priorities and service types.
Innovation Solution
A method and system that determine priority for each small cell relay node based on resource utilization and service types, allocating backhaul bandwidth accordingly to ensure higher-priority nodes receive a greater percentage of the total available bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If equal backhaul bandwidth is allocated to each small relay node, then device complexity is reduced and ease of operation is improved, but resource utilization efficiency deteriorates and quality of service worsens
Solution Approach 1:
The patent implements differentiated bandwidth allocation where each small relay node receives bandwidth proportional to its priority level. The relay node determines priority based on resource utilization metrics and service types, creating local quality variations in bandwidth distribution rather than uniform allocation. This resolves the contradiction by maintaining operational simplicity through automated priority-based allocation while improving resource utilization efficiency.
2Ease of operation
If equal backhaul bandwidth is allocated to each small relay node, then the system remains simple and easy to operate, but quality of service deteriorates due to bottlenecks
Solution Approach 1:
The patent changes the bandwidth allocation parameter from equal distribution to priority-proportional distribution. The relay node monitors resource utilization and service types to dynamically adjust bandwidth allocation parameters. This resolves the contradiction by maintaining ease of operation through automated parameter adjustment while improving quality of service by allocating more bandwidth to high-priority nodes with greater needs.
3Productivity
If priority-based bandwidth allocation is implemented, then resource utilization efficiency is improved and quality of service is enhanced, but device complexity increases
Solution Approach 1:
The relay node performs self-service by automatically determining priority levels based on monitored resource utilization and service type data. The system autonomously allocates bandwidth according to calculated priorities without requiring complex external control mechanisms. This resolves the contradiction by improving resource utilization efficiency through intelligent allocation while limiting complexity increase through self-service automation rather than manual configuration.
4Reliability
If priority-based bandwidth allocation is implemented, then quality of service is enhanced, but the system complexity increases
Solution Approach 1:
The relay node implements feedback mechanisms by continuously monitoring resource utilization and service types of connected small relay nodes. Based on this feedback, the relay node dynamically adjusts bandwidth allocation to maintain quality of service. This resolves the contradiction by enhancing quality of service through responsive allocation while managing system complexity through automated feedback-driven control rather than complex manual intervention.
