Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication network interfaces lack flexibility and simplicity in connecting different types of communication networks, often requiring static configurations and direct connections, which limits their adaptability and security in packet data transmission.
Innovation Solution
A method and arrangement that involves an access node reading and sending an identity-specific message to a contact node, enabling a packet data service between communication networks, with mutual authentication and secure data transmission through a VPN tunnel, allowing for flexible and secure interfacing regardless of network type or location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct connections are required for network interfacing, then connection reliability is improved, but network flexibility and adaptability deteriorate
Solution Approach 1:
The patent introduces an identity-specific message as an intermediary element that enables indirect network interfacing. Instead of requiring direct physical or logical connections between networks, the message carries identity information that allows contact nodes to establish secure packet data services dynamically. This resolves the contradiction by maintaining connection reliability through authenticated messaging while achieving network flexibility through dynamic, on-demand service establishment.
Solution Approach 2:
The patent implements dynamic network interfacing where packet data services are established temporarily based on identity verification rather than permanent direct connections. The contact node dynamically creates packet data services when identity-specific messages are received and terminates them when no longer needed. This dynamic approach improves adaptability while maintaining reliability through authenticated service establishment.
2Device complexity
If static configurations are used for network interfaces, then device complexity is reduced, but adaptability to different network types deteriorates
Solution Approach 1:
The patent changes the parameter of network interfacing from static configuration to dynamic parameter-based identification. Instead of configuring interfaces for specific network types, the system uses identity-specific messages containing network identifiers that allow the contact node to adapt to different network types dynamically. This reduces configuration complexity while maintaining high adaptability through parameter-driven service establishment.
Solution Approach 2:
The patent creates a universal interfacing mechanism where the contact node can handle multiple network types through a single identity verification process. The identity-specific message format is universally applicable across different network types, allowing the same contact node to interface with various access networks without requiring type-specific configurations. This achieves both simplicity and versatility.
3Reliability
If mutual authentication is implemented, then security is improved, but processing time and complexity increase
Solution Approach 1:
The patent implements preliminary authentication by verifying identities through identity-specific messages before establishing packet data services. The authentication process is performed in advance during service setup, allowing subsequent data transmission to proceed without repeated authentication overhead. This maintains high security while reducing ongoing processing time by front-loading the authentication step.

AI summary
An operational method interfaces a second communication network containing an access node with a first communication network encompassing a contact node. In a first step, an access node reads or receives an identity which is specific for the second communication network and is stored in a storage medium of a memory node. Then an interfacing message containing the identity that is specific for the second communication network is transmitted from the access node to the contact node, which is defined by an address stored in the storage medium. A packet data service to the access node is supplied by the contact node such that the second communication network is interfaced with the first communication network. An assembly and a storage medium are provided for interfacing the second communication network with the first communication network.
