Solution Overview

Problem

There is no effective solution for controlling unicast and multicast connections in the 5G New Radio (NR) Vehicle to Everything (V2X) system, specifically regarding how a network device manages terminal device connections.

Innovation Solution

A connection configuration method where terminal devices report their connection status to a network device, and the network device configures and controls these connections accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If terminal devices establish unicast or multicast connections autonomously in 5G NR V2X system, then connection establishment speed is improved, but network device control capability deteriorates

Engineering Contradiction:
Improveconnection establishment speedVSAvoidnetwork device control capability
Core Design Contradiction:
SpeedVSEase of operation

Solution Approach 1:

The patent implements feedback mechanisms where terminal devices report connection status information to network devices. This allows the network device to receive feedback about established connections and adjust control strategies accordingly, resolving the contradiction between autonomous connection establishment and network control capability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent enables terminal devices to perform preliminary connection establishment actions autonomously without waiting for network device instructions. This preliminary action speeds up connection establishment while the network device retains control through subsequent configuration and management operations.

Inventive Principle:
Principle #10Preliminary action

2Extent of automation

If terminal devices autonomously manage connections without network intervention, then device autonomy is improved, but connection management reliability deteriorates

Engineering Contradiction:
Improvedevice autonomyVSAvoidconnection management reliability
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The network device acts as an intermediary between terminal devices, receiving connection status reports and providing configuration instructions. This intermediary role maintains reliability by ensuring centralized coordination while allowing terminal devices operational autonomy in establishing connections.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent implements dynamic connection management where terminal devices can autonomously adjust connection parameters based on real-time conditions, while the network device dynamically updates configurations. This dynamic approach balances device autonomy with reliable network-controlled management.

Inventive Principle:
Principle #15Dynamics
