Solution Overview

Problem

Existing telecommunication networks face challenges in efficiently managing flexible channel bandwidth allocation for guest operators in shared radio unit architectures, leading to potential bandwidth overlap and inefficiencies.

Innovation Solution

Implementing a resource allocator that dynamically reallocates bandwidth among guest operators using an open front-haul interface, allowing for flexible channel bandwidth allocation by adjusting bandwidth zones to accommodate non-traffic signals extending beyond the allocated bandwidth, and ensuring no overlap through communication with neighboring operators.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If static bandwidth allocation is used for guest operators in shared RU architecture, then resource management is simplified, but network performance is reduced due to inability to accommodate dynamic bandwidth demands and non-traffic signals

Engineering Contradiction:

Improvenetwork performanceVSAvoidresource management complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic bandwidth allocation by allowing the host operator to reallocate bandwidth zones among guest operators based on current network conditions and demand. The resource allocator continuously adjusts allocated bandwidths, enabling the system to transition from static to dynamic resource management, thereby improving network performance while maintaining manageable complexity through automated control.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the bandwidth allocation parameter dynamically by adjusting the bandwidth zone boundaries and allocated bandwidth values according to real-time network conditions. This parameter change enables the system to accommodate varying traffic demands and non-traffic signals, resolving the contradiction between performance and management simplicity.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If fixed bandwidth zones are allocated to guest operators, then allocation is straightforward, but bandwidth overlap occurs when non-traffic signals extend beyond allocated bandwidth

Engineering Contradiction:

Improvebandwidth allocation accuracyVSAvoidbandwidth allocation simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The resource allocator receives feedback about actual bandwidth usage and non-traffic signal requirements from the network operations. This feedback mechanism enables the system to detect when bandwidth extensions are needed and automatically adjust allocations, ensuring accuracy while maintaining operational simplicity through automated response to feedback.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary actions by pre-configuring bandwidth zones and establishing clear allocation boundaries before actual usage occurs. The resource allocator proactively adjusts allocations based on predicted needs and contractual agreements, preventing overlap issues before they arise while maintaining straightforward allocation processes.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If flexible bandwidth reallocation is implemented, then network efficiency is improved, but coordination complexity increases due to need to communicate with neighboring operators

Engineering Contradiction:

Improvenetwork efficiencyVSAvoidcoordination complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The host operator's resource allocator acts as an intermediary between guest operators and the shared radio unit. This intermediary manages all bandwidth reallocation coordination, handling communications with neighboring operators and adjusting allocations automatically. This mediator approach improves network efficiency while containing coordination complexity within a centralized management function.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The resource allocator performs multiple functions including bandwidth allocation, reallocation coordination, neighbor operator communication, and conflict resolution within a single unified system. This multi-functional approach enables flexible bandwidth reallocation to improve efficiency while managing coordination complexity through consolidation rather than dispersion across multiple separate systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Technologies for shared radio unit architectures supporting flexible channel bandwidth allocation are described. One method includes receiving, from a guest operator of a plurality of guest operators of a telecommunications network, a request for resources from a host operator, wherein each guest operator of the plurality of guest operators shares a radio unit provided by the host operator, determining whether the request for resources is satisfiable based on a current resource allocation for the guest operator, and in response to determining that the request for resources is not satisfiable based on the current resource allocation, allocating additional resources to the guest operator, wherein the additional resources are obtained from one or more additional guest operators of the plurality of guest operators.
