Solution Overview

Problem

The increasing geographical separation of user areas in communication systems necessitates a large number of optical fibers for direct data connections between remote base stations and central baseband units, leading to inefficiencies in data transmission.

Innovation Solution

A data processing apparatus connected to multiple remote base stations and a central site device via a reduced number of optical fibers, which aggregates and splits data flows to enable efficient communication, reducing the overall optical fiber requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If each remote base station is connected to a central site device through one optical fiber or one pair of optical fibers in a point-to-point manner, then data transmission reliability is improved, but the quantity of optical fibers required increases significantly

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidquantity of optical fibers
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent merges multiple point-to-point optical fiber connections into a shared optical fiber network. Multiple remote base stations are connected to a central site device through a common optical fiber infrastructure, allowing multiple data streams to share the same physical medium. This combining approach maintains reliable data transmission while significantly reducing the total quantity of optical fibers required from individual dedicated connections to a shared infrastructure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a universal optical fiber connection model where a single optical fiber or fiber pair serves multiple remote base stations simultaneously. The central site device acts as a multi-functional hub that can communicate with multiple remote base stations through shared optical fibers, enabling one fiber infrastructure to perform multiple communication functions that would traditionally require separate dedicated fibers.

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

2Adaptability or versatility

If remote base stations are geographically distributed and connected individually to BBUs, then network coverage and adaptability are improved, but device complexity and optical fiber requirements increase

Engineering Contradiction:
Improvenetwork adaptabilityVSAvoidnetwork complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the network into functional units where remote base stations are logically grouped and connected through a shared optical fiber infrastructure to a central site device. This segmentation allows the system to maintain network adaptability for geographically distributed locations while reducing overall network complexity by using a standardized shared connection model rather than individual dedicated connections for each remote station.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The central site device acts as an intermediary that mediates communications between multiple remote base stations and the core network. Instead of each remote base station having direct individual connections, the central site device serves as a mediator that manages and routes traffic from multiple remote stations through shared optical fibers, reducing the complexity of individual connections while maintaining network adaptability.

Inventive Principle:
Principle #24Intermediary (Mediator)
