Solution Overview

Problem

Existing network selection methods for terminal devices are inflexible and rely on a single, fixed selection list, which fails to adapt to changing locations and network availability, leading to suboptimal network choices.

Innovation Solution

A network selection method that determines a corresponding selection parameter from a dynamic selection parameter set based on current location information, allowing for flexible network selection between PLMN and NPN.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single fixed selection list is used for network selection, then the network selection process is simple, but it cannot adapt to changing locations and network availability

Engineering Contradiction:
Improvenetwork selection adaptabilityVSAvoidselection parameter set complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by transforming the static fixed selection list into a dynamic selection parameter set that can be updated based on location information. The selection parameter set includes multiple subsets corresponding to different locations, allowing the terminal device to dynamically select appropriate parameters as it moves between different geographic areas, thus achieving adaptability without excessive complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter structure from a single fixed list to a multi-subset parameter set where each subset contains location-specific selection parameters. By organizing parameters into multiple subsets that can be selectively applied based on current location, the system achieves both adaptability to different scenarios and manageable complexity through structured organization.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If location-based dynamic selection is implemented, then network selection flexibility is improved, but the complexity of the selection parameter set increases

Engineering Contradiction:
Improvenetwork selection flexibilityVSAvoidselection parameter set structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent segments the selection parameter set into multiple subsets, where each subset corresponds to a specific location or scenario. This segmentation allows the terminal device to only process and evaluate parameters relevant to its current location, making the operation simple and flexible while keeping the overall structure organized and manageable through clear division into location-specific groups.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple selection parameter subsets are stored, then adaptability to different locations is improved, but the storage requirements and processing complexity increase

Engineering Contradiction:
Improvelocation-based network selectionVSAvoidselection parameter data volume
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent applies preliminary action by pre-configuring multiple selection parameter subsets corresponding to different locations before the terminal device needs to make network selection decisions. The network device sends these pre-prepared parameter subsets to the terminal device in advance, so that when the terminal device moves to a new location, it can immediately use the pre-configured parameters without needing to process or generate new parameters on the fly, thus reducing real-time processing complexity and data volume requirements.

Inventive Principle:
Principle #10Preliminary action
