Solution Overview

Problem

Satellite communication systems face challenges in integrating legacy terminals with newer technologies without the need for dedicated spectrum and expensive hardware, as service providers are reluctant to sacrifice existing spectrum for older devices due to efficiency and cost-effective reasons.

Innovation Solution

A satellite communication system that uses a base station capable of communicating with multiple generations of terminals, including 2.5G, 3G, and 4G devices, by employing a common physical layer and multi-protocol stack to route traffic and process data packets from different terminal types, allowing for backward compatibility without dedicated spectrum allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If satellite communication systems allocate dedicated spectrum and hardware for legacy terminals, then backward compatibility is maintained, but spectrum efficiency decreases and costs increase

Engineering Contradiction:
Improvebackward compatibilityVSAvoidspectrum efficiency
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The base station implements a multi-protocol stack that can simultaneously handle multiple terminal generations (2.5G, 3G, 4G) using a common physical layer. This universal approach allows the same hardware and spectrum to serve multiple protocol types, eliminating the need for dedicated legacy infrastructure while maintaining backward compatibility.

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

Solution Approach 2:

The patent merges legacy terminal support into the modern network infrastructure by integrating multiple protocol stacks within the base station. Instead of separate dedicated systems, legacy and modern terminals share the same physical layer and spectrum resources, with traffic routed through appropriate protocol handlers.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If satellite communication systems continue supporting older technologies with dedicated spectrum, then legacy terminals remain operational, but service provider costs increase

Engineering Contradiction:
Improvelegacy terminal supportVSAvoidservice provider costs
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The base station is designed with universal multi-functionality, incorporating protocol stacks for multiple terminal generations within a single platform. This eliminates the need for separate legacy infrastructure, reducing hardware costs and spectrum allocation expenses while maintaining support for older terminals.

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

Solution Approach 2:

The system recovers spectrum resources previously dedicated to legacy terminals by integrating them into the shared modern infrastructure. Legacy terminals continue to operate but consume resources from the pooled spectrum rather than dedicated allocations, allowing providers to reallocate or optimize spectrum usage.

Inventive Principle:
Principle #34Discarding and recovering

3Reliability

If satellite communication systems use separate infrastructure for different terminal generations, then protocol compatibility is ensured, but device complexity increases

Engineering Contradiction:
Improveprotocol compatibilityVSAvoidnetwork infrastructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The base station architecture segments protocol handling into distinct logical layers while maintaining a unified physical layer. Each terminal generation has its own protocol stack that processes traffic independently, but all stacks share common radio frequency resources and physical transmission media, reducing overall system complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The common physical layer acts as an intermediary between multiple protocol stacks and the radio interface. It mediates between different terminal generations by providing a unified access point, simplifying the interaction between legacy and modern protocols while ensuring reliable communication for all terminal types.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

An apparatus for establishing communication between a base station and different generation terminals includes a multi-protocol stack capable of processing user traffic received from different generation terminals. The apparatus also includes a common physical layer that receives user traffic from different generation terminals and identifies the generation of the terminal sending the user traffic. The user traffic is then processed and routed based on the terminal generation. Traffic can be prioritized across current and legacy terminal types based on a variety of factors.
