Solution Overview

Problem

Current Radio Access Network (RAN) systems for tele-operation, while providing high bandwidth and interference management, suffer from significant signal latency due to extended connections between mobile devices and RPVs, which can exceed 20 mSec, impacting control loop efficiency and safety.

Innovation Solution

Integration of a Mobile Edge Computing server with radio transceiver equipment to host a virtual Rendezvous Point, minimizing latency by locating the Rendezvous Point at the network edge, thus reducing the distance between mobile devices and the Rendezvous Point.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the Rendezvous Point is located in the core data/transport network, then network management and interference control capabilities are improved, but signal latency increases significantly

Engineering Contradiction:
Improveinterference management capabilityVSAvoidsignal latency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent segments the network architecture by deploying virtual Rendezvous Points at multiple levels: edge locations close to users/devices and core network locations. This segmentation allows latency-sensitive traffic to be handled at the edge while maintaining core network management capabilities, thereby resolving the contradiction between centralized control reliability and signal latency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a spatial dimension to the Rendezvous Point deployment by distributing VRP instances across different network locations (edge and core) rather than relying on a single centralized location. This multi-dimensional deployment enables the system to simultaneously achieve low latency for local traffic and robust interference management through core network coordination.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Quantity of substance

If extended connections are established between mobile devices and RPVs through the core network, then bandwidth and coverage are improved, but round-trip control delay increases

Engineering Contradiction:
Improvedata bandwidthVSAvoidround-trip control delay
Core Design Contradiction:
Quantity of substanceVSLoss of time

Solution Approach 1:

The patent establishes preliminary local connections between mobile devices and edge-located virtual Rendezvous Points before core network involvement is needed. This preliminary action at the network edge minimizes initial signal latency, while core network resources remain available for bandwidth-intensive operations and interference management when required.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces virtual Rendezvous Points at the network edge as intermediary nodes between mobile devices and the core network. These edge VRP intermediaries handle latency-sensitive control signals locally, while core network VRP intermediaries manage bandwidth-intensive data flows and coordination, thereby resolving the bandwidth-latency tradeoff.

Inventive Principle:
Principle #24Intermediary (Mediator)
