Solution Overview

Problem

Existing network sharing solutions in LTE systems are inflexible, leading to inefficient spectrum resource utilization due to fixed frequency band allocation, resulting in excessive resource occupation by one operator while others have insufficient resources, which fails to improve spectrum utilization rates and increases operational costs.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed frequency band allocation is used for network sharing, then network sharing can be achieved, but spectrum resource utilization is inefficient and one operator may occupy excessive resources while others have insufficient resources

Engineering Contradiction:

Improvenetwork sharing capabilityVSAvoidspectrum resource utilization

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements dynamic bandwidth allocation where the base station continuously monitors bandwidth usage by each operator and adjusts resource allocation in real-time based on current service demands. This transforms the static fixed allocation into a dynamic system that adapts to changing conditions, allowing operators to flexibly share resources without being constrained by pre-assigned frequency bands.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the allocation parameters from fixed frequency bands to flexible bandwidth resources that can be dynamically adjusted. The base station monitors bandwidth occupation information and modifies the allocation parameters (bandwidth size, resource block distribution) based on real-time operator needs and service demands, thereby optimizing spectrum utilization while maintaining network sharing.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If fixed frequency band allocation is used, then operator bandwidth and carrier frequency are determined, but flexible scheduling cannot be achieved and spectrum utilization rate cannot be improved

Engineering Contradiction:

Improveoperator bandwidth determinationVSAvoidflexible scheduling capability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system transitions from static frequency band assignment to dynamic bandwidth scheduling. The base station continuously monitors service demands and bandwidth usage, then adjusts resource allocation dynamically. This enables flexible scheduling where operators can adapt their bandwidth usage based on real-time conditions without being constrained by fixed frequency assignments.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements a feedback mechanism where the base station monitors bandwidth occupation information from each operator and uses this information to adjust future allocations. The system continuously collects data on actual bandwidth usage and service demands, then modifies allocation parameters accordingly, enabling flexible scheduling that responds to changing operational conditions.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If fixed frequency band allocation is used, then network sharing is established, but investment and operation costs are not reduced due to inefficient resource utilization

Engineering Contradiction:

Improvenetwork sharing establishmentVSAvoidoperational costs

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent optimizes operational efficiency by changing from fixed to dynamic allocation parameters. The base station monitors actual bandwidth usage and adjusts resource distribution to match real demands, eliminating waste from underutilized or over-allocated resources. This optimization reduces operational costs while maintaining network sharing benefits.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system enables operators to self-regulate their bandwidth usage through the monitoring and feedback mechanism. The base station automatically detects bandwidth occupation and adjusts allocations without manual intervention, allowing the network to self-optimize resource distribution and reduce operational inefficiencies that would otherwise increase costs.

Inventive Principle:

Principle #25Self-service
