Solution Overview

Problem

Traditional 3GPP tunnel/bearer-based connection-oriented architectures are inefficient for future mobility networks due to high signaling overhead in mobility handovers, especially with diverse end devices like XR and IoT, necessitating a more efficient connectionless architecture.

Innovation Solution

Implementing a Relativistic Routing Protocol (RRP) that uses IP-based communication channels and RRP agents, routers, and a WAT controller to manage connections across different wireless technologies, eliminating the need for GTP tunneling setup and tear down, allowing multiple simultaneous active connections and optimizing routing based on real-time conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional 3GPP tunnel/bearer-based connection-oriented architecture is used, then mobility handover can be managed, but signaling overhead is high and network scalability is poor

Engineering Contradiction:

Improvemobility handover managementVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and removes the GTP tunneling layer from the architecture, replacing connection-oriented tunnel management with connectionless IP routing. This eliminates the signaling overhead associated with tunnel setup and teardown while maintaining mobility handover capability through standard IP routing protocols.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the fundamental parameter of connection management from connection-oriented (GTP tunnels) to connectionless (IP packets). This parameter change transforms the architecture from requiring explicit tunnel setup/teardown to using standard IP routing, significantly reducing signaling overhead while maintaining reliability.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If GTP tunneling is used for every data path, then connection-oriented reliability is achieved, but network efficiency and latency are degraded

Engineering Contradiction:

Improveconnection-oriented reliabilityVSAvoidlatency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary routing setup at network infrastructure level rather than requiring per-connection tunnel establishment. Routes are pre-configured in routing tables, enabling immediate packet forwarding without latency-inducing tunnel setup procedures for each data path.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces the mechanical tunnel establishment process with automated IP routing based on routing tables. This substitution eliminates the step-by-step tunnel configuration overhead and reduces latency through direct packet forwarding based on destination IP addresses.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If connection-oriented architecture is used, then data path control is precise, but device complexity and energy consumption increase for billions of IoT devices

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent enables devices to communicate using standard IP protocols without requiring network-managed tunnel connections. Devices independently route packets using IP addresses, eliminating the energy-consuming tunnel setup/teardown processes while maintaining data path control through standard IP routing mechanisms.

Inventive Principle:

Principle #25Self-service
