Solution Overview

Problem

In 5G NR communication technology, network feature capabilities conflict during registration procedures over different types of access networks, particularly between 3GPP and non-3GPP access networks, leading to inconsistencies in service network features.

Innovation Solution

User equipment (UE) determines the registration order of access networks and adopts the corresponding setting values for network feature capabilities, ensuring consistency by prioritizing the latest registration procedure's settings when both networks are on the same PLMN, or using specific settings for each access type when they are not.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the UE adopts different network feature capability settings for different access networks, then the network feature capabilities can be optimized for each specific access type, but conflicts and inconsistencies arise when multiple access networks are registered on the same PLMN

Engineering Contradiction:

Improvenetwork feature capability optimizationVSAvoidservice network feature consistency

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements dynamic selection of network feature capability settings based on the temporal order of registration procedures. The UE dynamically determines which access network's settings to apply by comparing registration timestamps, allowing the system to adapt between different access networks (3GPP and non-3GPP) while maintaining consistency within the same PLMN context.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter selection criteria from static (access network type) to dynamic (registration timing). By introducing temporal parameters (registration procedure timing) as the decision criterion, the system resolves conflicts between different network feature capability settings while maintaining adaptability to different access types.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If the UE prioritizes the latest registration procedure's settings, then consistency across the same PLMN is improved, but the complexity of determining registration order increases

Engineering Contradiction:

Improveservice network feature consistencyVSAvoidregistration procedure tracking

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by establishing registration timestamps at the moment of each registration procedure. This pre-recorded temporal information is then used later to resolve capability conflicts, eliminating the need for complex real-time comparison logic and simplifying the decision-making process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses copying by storing timestamp information from registration procedures as reference data. These copied temporal references are then compared to determine which network's settings to apply, avoiding the need to re-analyze entire registration procedures and reducing computational complexity.

Inventive Principle:

Principle #26Copying

3Adaptability or versatility

If the UE maintains separate network feature capability settings for each access network, then adaptability to different access types is improved, but conflicts arise during cross-access network registration

Engineering Contradiction:

Improveaccess network-specific optimizationVSAvoidregistration procedure simplicity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent implements dynamic resolution of capability conflicts by using registration timing as the deciding factor. This dynamic approach allows the UE to maintain separate settings for different access networks while automatically resolving conflicts through a simple temporal comparison, keeping the operation straightforward despite multiple access network registrations.

Inventive Principle:

Principle #15Dynamics

AI summary

A method for handling network feature capabilities is provided. The method includes a UE determining whether a first access network with a first access type and a second access network with a second access type are registered on the same PLMN; if the first access network and the second access network register on the same PLMN, the UE determines whether a first registration procedure over the first access network occurred earlier than the second registration procedure over the second access network. The first registration procedure corresponds to first setting values for a plurality of network feature capabilities and the second registration procedure corresponds to second setting values for the network feature capabilities. If the first registration procedure over the first access network occurred earlier than the second registration procedure over the second access network, the UE adopts the second setting values for the network feature capabilities.
