Solution Overview

Problem

Current technologies lack a solution for the service capability exposure function (SCEF) to find network elements within a dedicated core network, or network slice, which is essential for managing diverse network requirements across different applications.

Innovation Solution

A network slice management system that includes a communicator, processor, and memory, capable of receiving network element address queries from the SCEF, obtaining network slice information, and determining the IP address of specific network elements based on feature names or identifiers, allowing the SCEF to communicate effectively with network elements within a core network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the SCEF needs to find network elements in a dedicated core network (network slice), then the adaptability for managing diverse network requirements is improved, but the device complexity increases due to the need for additional mapping and query mechanisms

Engineering Contradiction:
Improveadaptability for managing diverse network requirementsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a dedicated core network identifier mapping mechanism that acts as an intermediary between the SCEF and network elements in dedicated core networks. The mapping stores correspondences between dedicated core network identifiers and network element identifiers, enabling the SCEF to query and locate network elements without direct access to internal routing information, thus managing diverse network requirements while controlling complexity

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the network identification process into distinct components: network slice identification, mapping storage, and query resolution. By dividing the complex task of finding network elements in specialized networks into manageable segments, the system achieves adaptability for different network types while keeping each component's complexity controlled

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If network slice information is stored and mapped to enable SCEF queries, then the measurement precision for locating network elements is improved, but the loss of information increases due to the additional mapping layer

Engineering Contradiction:
Improveprecision for locating network elementsVSAvoidinformation loss through mapping
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent creates a virtual copy of the network element identification space through the mapping mechanism. Instead of directly accessing complex internal routing information, the system maintains a simplified mapping copy that preserves the essential correspondence between identifiers and network elements, achieving precise location while minimizing information loss through selective abstraction

Inventive Principle:
Principle #26Copying

3Ease of operation

If the SCEF queries network element addresses through a management apparatus, then the ease of operation is improved, but the loss of time increases due to additional query and resolution steps

Engineering Contradiction:
Improveease of operation for SCEFVSAvoidtime loss in query and resolution
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent performs preliminary actions by pre-establishing and storing mappings between dedicated core network identifiers and network element identifiers before queries are needed. This advance preparation enables the SCEF to quickly resolve network element locations through simple lookups rather than complex real-time routing calculations, improving ease of operation while minimizing query time

Inventive Principle:
Principle #10Preliminary action
