Network Configuration Validity Control for Terminal Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication network sharing methods allow for random handovers between equivalent networks, leading to unrestricted terminal access and reduced flexibility in network sharing.
Innovation Solution
A method where a core-network device sends network configuration information to a terminal device, including validity configuration information that specifies the validity conditions of equivalent communication networks, allowing the terminal to determine whether to access or re-select cells based on matching network parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If network sharing is implemented without validity conditions, then terminal access flexibility is improved, but network security and access control deteriorate
Solution Approach 1:
The patent introduces validity condition parameters (frequency band, tracking area, cell ID, geographic region) that dynamically control network access. The terminal device evaluates these parameters to determine whether to access equivalent communication networks, transforming the access control mechanism from unconditional to parameter-based conditional access, thereby maintaining flexibility while ensuring security.
2Adaptability or versatility
If random handover between equivalent networks is allowed, then network sharing capability is improved, but access control precision deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the terminal device receives validity condition information from the network, evaluates it against current network parameters, and makes informed access decisions. This closed-loop control replaces random handover with intelligent, condition-based access control, achieving both network sharing and precise control.
Solution Approach 2:
The patent uses multiple parameters (frequency band, tracking area, cell ID, geographic region) to precisely define access conditions. By changing from unconditional access to multi-parameter conditional access, the system achieves both network sharing capability and access control precision simultaneously.
3Measurement precision
If validity configuration information is provided, then access control precision is improved, but device complexity increases
Solution Approach 1:
The network device pre-configures validity condition information before terminal access, including frequency band, tracking area, cell ID, and geographic region parameters. This preliminary configuration eliminates the need for complex real-time decision-making at the terminal, as the terminal simply evaluates received conditions against current network state, reducing terminal complexity while maintaining precision.
