Private Network Service via APN-OI Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional private network access technologies are dependent on mobile communication terminals having an Access Point Name (APN) selection function, limiting their application to terminals that do not support this feature and complicating the incorporation of this function into new terminals, as well as increasing manufacturing and maintenance costs.
Innovation Solution
A private network service system that includes a service link server, a home subscriber server, and a mobility management entity, which identifies and authenticates mobile communication terminals, changes their public APN-Operator Identifier to a private one, and induces connections to either a public or private gateway based on the terminal's subscriber profile, allowing connection to a private network without requiring the terminal to support APN selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional private network access technology uses APN selection function in mobile communication terminals, then private network connection is enabled, but terminal dependency increases and manufacturing complexity increases
Solution Approach 1:
The patent introduces a service link server as an intermediary component in the network infrastructure that handles APN-OI modification requests. This server acts as a mediator between the mobile communication terminal and the home subscriber server, processing authentication and APN changes without requiring the terminal itself to have complex APN selection functionality. The service link server receives requests from terminals, communicates with the home subscriber server for authentication, and manages the APN-OI modification process, thereby transferring the complexity from the terminal to the network side.
Solution Approach 2:
The patent enables the network infrastructure to automatically manage private network access by having the service link server and home subscriber server handle authentication and APN-OI modification autonomously. When a terminal requests private network access, the system automatically verifies credentials against the home subscriber server, modifies the APN-OI accordingly, and routes the connection without requiring manual configuration or complex terminal-side decision logic. This self-service mechanism eliminates the need for terminals to maintain APN selection functions.
2Reliability
If conventional private network access technology requires terminal-based APN selection, then private network access is achieved, but adaptability to different terminal types decreases
Solution Approach 1:
The service link server serves as a universal intermediary that standardizes the interface between diverse terminal types and the private network infrastructure. By centralizing the authentication and APN-OI modification logic in the service link server, the system can accommodate terminals with varying capabilities - whether they have advanced APN selection functions or are simple terminals without such capabilities. The intermediary translates various terminal requests into a standardized process that the network can handle uniformly.
Solution Approach 2:
The patent creates a universal access mechanism where the service link server and home subscriber server combination can serve multiple types of terminals with different capabilities. The system is designed to handle both sophisticated terminals with APN selection functions and basic terminals without such functions, providing a unified private network access solution. The network-side infrastructure performs the intelligent routing and authentication functions that would otherwise need to be present in every terminal, making the service universally applicable.
3Reliability
If conventional private network access technology incorporates APN selection function into terminals, then private network connection is enabled, but manufacturing cost increases
Solution Approach 1:
The service link server acts as a network-side intermediary that assumes the functional burden of APN selection and management, eliminating the need to incorporate complex APN selection hardware or software into every terminal device. This shifts the manufacturing complexity from the terminal production process to the network infrastructure, allowing terminals to be manufactured with simpler, more cost-effective components while still enabling private network access through the network's intelligent mediation.
Solution Approach 2:
The system implements self-service authentication and APN-OI modification through the service link server and home subscriber server interaction. The network infrastructure automatically handles credential verification, APN determination, and connection routing without requiring terminals to possess complex decision-making capabilities. This self-service approach allows terminals to be manufactured as simpler devices that merely initiate connections, while the network performs the sophisticated management functions, thereby reducing terminal manufacturing costs.
