Terminal Access to Non-Public and Public Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies are unclear about how a terminal accesses both a non-public communication network and a public communication network, leading to challenges in registration and service provision for vertical industries.
Innovation Solution
The proposed solution involves a network access method that includes obtaining certificate information related to a non-public communication network, determining preset conditions, and sending specific information to access both non-public and public communication networks, thereby clarifying the access process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal accesses both non-public communication network and public communication network, then service continuity and roaming are improved, but the complexity of network access management increases
Solution Approach 1:
The patent segments the network access process by introducing separate registration mechanisms for non-public networks (PN) and public networks (PLMN). The terminal performs independent registration with the non-public network through specific network elements (AMF, RAN) while maintaining separate registration with public networks, allowing service continuity without mixing access procedures.
Solution Approach 2:
The patent introduces intermediary network elements (AMF - Access and Mobility Management Function, and RAN - Radio Access Network) that mediate between the terminal and both non-public and public networks. These intermediaries handle the complexity of dual-network registration transparently, managing certificate verification and access coordination without exposing complexity to the terminal.
2Reliability
If certificate information is obtained for non-public network access, then security is improved, but the access process complexity increases
Solution Approach 1:
The patent implements preliminary action by obtaining and verifying certificate information before the terminal accesses the non-public network. The network elements (AMF, RAN) perform certificate verification in advance during the registration process, ensuring security requirements are met before service activation, thus preventing security issues rather than reacting to them.
3Reliability
If separate registration processes are implemented for non-public and public networks, then network isolation is improved, but registration time increases
Solution Approach 1:
The patent merges the registration processes by allowing the terminal to perform registration with both non-public networks and public networks through a unified access mechanism. The terminal can initiate registration requests that are handled by appropriate network elements for each network type simultaneously or in optimized sequence, reducing total registration time while maintaining network isolation through separate certificate verification paths.
