Problem

In air traffic control communication systems, the existing technologies face challenges in managing bandwidth efficiently, especially when multiple workstations and radio devices are involved, leading to increased bandwidth requirements and potential blockages, which complicates the transfer of voice signals and signaling information across geographically distributed components.

Innovation Solution

The implementation of a communication system that uses wide area networks for voice and signaling information transfer, with control units managing the distribution of voice signals and radio devices, ensuring deterministic and minimized bandwidth requirements, allowing multiple workstations to access all radio devices via a network, and providing fail-safe connections and efficient data transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple workstations and radio devices are connected directly to establish communication links, then communication coverage and accessibility are improved, but bandwidth requirements increase and network blockages occur

Engineering Contradiction:
Improvecommunication coverageVSAvoidbandwidth requirements
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

A communication server is introduced as an intermediary component between workstations and radio devices. The server receives voice signals from workstations, manages radio resource allocation, and relays signals to appropriate radio devices. This centralized mediation reduces the need for multiple direct communication links, thereby optimizing bandwidth utilization while maintaining comprehensive communication coverage across the air traffic control system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If each workstation establishes direct communication links with multiple radio devices, then communication flexibility is improved, but device complexity and network management difficulty increase

Engineering Contradiction:
Improvecommunication flexibilityVSAvoidnetwork management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The communication server acts as a central management intermediary that handles radio resource allocation, frequency assignment, and communication routing. Workstations interact with the server through standardized interfaces, while the server manages the complex relationships with multiple radio devices. This architecture maintains communication flexibility for air traffic controllers while significantly reducing network management complexity through centralized control.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The communication server provides multiple functions including voice signal routing, radio resource management, frequency coordination, and communication monitoring. By consolidating these diverse functions into a single multi-functional system, the patent reduces overall network complexity while maintaining the flexibility needed for various air traffic control operations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Speed

If voice signals are transferred directly between workstations and radio devices, then data transfer speed is improved, but signal quality and reliability deteriorate due to interference and blockages

Engineering Contradiction:
Improvedata transfer speedVSAvoidsignal quality
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The communication server serves as a protected intermediary that receives voice signals from workstations, processes them through error checking and signal conditioning, and relays them to radio devices. This centralized processing path protects signals from direct exposure to radio frequency interference and network blockages, thereby improving signal quality and reliability while maintaining efficient data transfer speeds through optimized routing.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Speed

If direct communication links are established between all workstations and radio devices, then real-time communication is improved, but system vulnerability to failures increases

Engineering Contradiction:
Improvereal-time communicationVSAvoidsystem vulnerability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The communication server provides a protected intermediary pathway for real-time voice communication between workstations and radio devices. By centralizing signal routing and management, the server creates a more resilient system architecture where failures in individual direct links do not compromise overall system operation. The server can reroute signals through alternative paths, reducing system vulnerability while maintaining real-time communication capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method and a communications system for speech communication includes a plurality of workstations and a plurality of radio transmission devices and radio receiving devices. There are control units in the signal path between the workstations and the radio transmission devices and the radio receiving devices. The control units select the speech signals of one of the workstations according to predetermined or predeterminable criteria when there is a simultaneous plurality of operating signals of a plurality of workstations, or overlap the speech signals of a plurality of workstations according to predefined criteria, and transmit the speech signal thus obtained, chosen or overlapped for sending on the radio transmission device. Further, the control units transmit a receiving signal to the workstations connected thereto when the speech signals transmitted from the radio receiving unit are present, and transfer the speech signals to said workstations.
