Solution Overview

Problem

Terminal devices face challenges in identifying whether received identification information is applicable to a public or non-public network, leading to inefficient communication due to overlapping identifiers and lack of clear indications.

Innovation Solution

A method and device for information transmission that enable terminal devices to determine the network applicability of identification information based on indications from network devices, environmental context, or content, using schemes such as network identification codes, field values, and field presence to differentiate between public and non-public networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If terminal devices use common identification information for both public and non-public networks, then network compatibility is improved, but network identification accuracy deteriorates

Engineering Contradiction:

Improvenetwork compatibilityVSAvoidnetwork identification accuracy

Core Design Contradiction:

Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The identification information is segmented into multiple fields, including a network type indication field that specifically identifies whether the identifier is for a public network or non-public network. This segmentation allows the same identifier structure to be used across both network types while maintaining clear distinction through the indication field.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A network type indication field is introduced as an intermediary element within the identification information. This intermediary explicitly indicates the network type (public or non-public), allowing terminal devices to accurately determine the applicable network without confusion, while maintaining compatibility with existing identifier structures.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If identification information structure is simplified for ease of use, then ease of operation is improved, but information completeness deteriorates

Engineering Contradiction:

Improveease of useVSAvoidinformation completeness

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The identification information structure is designed to be universal, serving both public and non-public networks with the same basic format. The network type indication field enables this structure to function across different network types without requiring separate identifier systems, maintaining simplicity while providing complete network identification capability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The present disclosure discloses a method and a device for information transmission, capable of enabling a terminal device to efficiently identify a network to which identification information it receive is to be applied. The method includes: receiving, by a terminal device, identification information transmitted by a network device; and determining, by the terminal device, whether the identification information is to be used in a non-public network based on an indication from the network device, an environment in which the identification information is received, or content of the identification information.
