Identifier Hash Mapping for Uniform Communication Load Distribution

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing communication network load distribution methods based on identifiers, such as those specified by 3GPP, often result in uneven or non-uniform distribution, particularly as the nature of identifiers becomes skewed, leading to disproportionate resource allocation.

Innovation Solution

Implementing a hash function and modulo operation to map identifiers to communication resources, breaking the dependence between identifier content and resource assignment, ensuring a more uniform distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If identifier-based load distribution is used as specified by 3GPP, then resource allocation is simplified and direct, but the distribution becomes uneven and non-uniform

Engineering Contradiction:

Improveresource allocationVSAvoiddistribution uniformity

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The patent introduces a hash function as an intermediary between the identifier and resource selection. The hash function processes the identifier (e.g., SUPI, GPSI) and transforms it into a uniformly distributed output that determines resource selection. This intermediary breaks the direct mapping between identifier patterns and resource allocation, ensuring even distribution while maintaining operational simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Speed

If direct mapping of identifiers to resources is used, then the process is simple and fast, but the distribution becomes skewed based on identifier content

Engineering Contradiction:

Improveprocessing speedVSAvoidload distribution balance

Core Design Contradiction:

SpeedVSManufacturing precision

Solution Approach 1:

The patent changes the parameter transformation method from direct mapping to hash-based transformation. Instead of directly mapping identifier values to resources, the system applies a hash function that transforms the identifier into a uniformly distributed parameter space. This maintains processing speed while achieving balanced load distribution across resources.

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If range or pattern-based distribution is used, then resource assignment is straightforward, but uniformity is compromised when identifier distributions are skewed

Engineering Contradiction:

Improveresource assignmentVSAvoiddistribution uniformity

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent replaces the mechanical/range-based distribution system with a mathematical hash-based system. Instead of using range or pattern matching to assign resources, the system uses hash functions to transform identifiers into uniformly distributed values that determine resource assignment. This substitution maintains ease of implementation while achieving uniform distribution even with skewed identifier patterns.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
