Virtual Overlay Network for Mobile Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication mechanisms over Internet networks lack complete mobility and security, as they rely on IP addresses for connectivity and security, leading to service disruptions when equipment is moved or changed.
Innovation Solution
The solution involves creating a virtual overlay network that uses service and user identifiers independent of IP addresses, allowing seamless connectivity and security maintenance across equipment changes without disrupting user-service connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IP addresses are used for connectivity and security, then equipment can be identified and secured, but mobility is limited and service disruptions occur when equipment is moved or changed
Solution Approach 1:
The patent introduces an intermediary layer (virtual overlay network with distributed hash table) between the physical equipment and the communication services. This intermediary decouples the stable service identification from the changing physical equipment identifiers, allowing equipment to move while maintaining continuous service access through the intermediary's routing and mapping capabilities
2Reliability
If security mechanisms are based on equipment IP addresses, then secure communication can be established, but security must be reinitialized when equipment changes, impacting service quality
Solution Approach 1:
The patent implements preliminary action by pre-establishing security associations at the service level rather than the equipment level. Security credentials and encryption keys are bound to service identifiers that remain constant, allowing security to be maintained continuously across equipment changes without reinitialization delays
3Adaptability or versatility
If communication is transferred from one piece of equipment to another, then mobility is achieved, but complete mobility without interrupting current communication is not enabled
Solution Approach 1:
The patent adds another dimension to communication by introducing a virtual overlay network layer above the physical network. This additional dimension allows communication to be routed through virtual paths that can seamlessly switch between physical equipment, enabling complete mobility while maintaining continuity through the virtual layer's routing capabilities

AI summary
The invention relates to a method for establishing communication between a user and a service, implemented by at least one server, by means of a telecommunication network, which method comprises:—registering the service, comprising the creation of a virtual overlay network for said service over said telecommunication network, and assigning and storing identifiers and a virtual address for this service and for this server; —registering the user with the service and with the virtual overlay network, comprising logging into a web interface suitable for triggering the assignment of a user identifier, as well as connecting a terminal used by the user, triggering the assignment and storage of an identifier and a virtual address of this terminal; and—routing data packets between the user and the service via a virtual connection established within the virtual overlay network on the basis of these virtual addresses.
