Solution Overview

Problem

Large language models in telecommunications networks primarily focus on general use cases without considering subscriber-related data or behavior, limiting their effectiveness in enhancing network service levels and efficiency.

Innovation Solution

Implement a unified vector repository entity that stores subscriber-specific embeddings, allowing for intelligent use of large language models by embedding subscriber data into queries, thereby enabling behavior-specific decisions and results, and integrating this entity within the 5G core network's unified data management layer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If large language models are used for general use cases without subscriber-related data, then the implementation is simpler and more cost-effective, but the network service level improvement and network efficiency enhancement are limited

Engineering Contradiction:
Improveimplementation simplicityVSAvoidnetwork service level
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent implements a nested architecture where the unified vector repository is integrated within the 5G core network's unified data management layer. The vector repository contains subscriber embeddings that are nested within the existing network architecture, allowing LLMs to access subscriber-specific data without requiring complete system redesign. This nested structure enables progressive enhancement from general to personalized applications.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent performs preliminary action by pre-processing and embedding subscriber-related data into the unified vector repository before the LLM queries are executed. Subscriber profiles, behavior patterns, and network data are transformed into vector embeddings in advance, stored in the vector repository, and then retrieved during query processing. This pre-processing enables faster and more accurate personalized responses.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If subscriber-specific data is embedded into LLM queries, then behavior-specific decisions and network efficiency improve, but the system complexity and data management requirements increase

Engineering Contradiction:
Improvenetwork efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The unified vector repository serves multiple functions: it stores subscriber profiles, behavior patterns, network data, and provides vector embeddings for various LLM applications. This multi-functional repository reduces the need for separate data storage systems for different purposes, managing complexity through consolidation rather than proliferation of separate systems.

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

Solution Approach 2:

The unified vector repository acts as an intermediary between the existing 5G core network data management system and the LLM application layer. It transforms diverse subscriber data into standardized vector embeddings that the LLM can process, while maintaining compatibility with existing network data structures. This intermediary layer shields the complexity of data transformation from both the network core and the LLM application.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a unified vector repository is integrated into the 5G core network, then subscriber-specific embeddings can be accessed for personalized services, but the integration complexity with existing network functions increases

Engineering Contradiction:
Improvepersonalized service capabilityVSAvoidintegration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the data management functionality by creating a distinct unified vector repository component within the 5G core network architecture. This segmented approach allows the vector repository to be developed, maintained, and scaled independently from other network functions, reducing integration complexity. The repository can be implemented as a separate microservice or module that interfaces with existing network functions through standardized APIs.

Inventive Principle:
Principle #1Segmentation
