Solution Overview

Problem

Conventional mobile communication networks inefficiently utilize frequency spectrum and lack integration with video broadcast networks, leading to wasted resources and complex system management due to fixed frequency allocation and independent operation of both networks.

Innovation Solution

A communication system that integrates mobile communication and video broadcast networks through a central control node allocating time slots and frequencies using a predetermined schedule algorithm, enabling efficient video broadcast and data communication by employing time division multiplexing (TDM) and/or frequency division multiplexing (FDM) within cell clusters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fixed frequency spectrum allocation is used in conventional mobile communication networks, then each cellular base station can operate independently without interference, but frequency spectrum resources are wasted when user demand varies and system complexity increases due to cell breathing methods

Engineering Contradiction:
Improveindependent base station operationVSAvoidfrequency spectrum waste
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent merges the mobile communication network and video broadcast network into a unified TDM-FDM system where broadcast transmission towers and cellular base stations share the same frequency spectrum resources through time division multiplexing, eliminating frequency spectrum waste while maintaining reliable operation

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements dynamic resource allocation where the central control node dynamically assigns time slots and frequency bands to different base stations and broadcast towers based on real-time user demand and traffic conditions, allowing the system to adapt rather than using static cell breathing methods

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If conventional mobile communication networks operate independently from video broadcast networks, then each network can be managed separately, but resource utilization efficiency decreases and system complexity increases

Engineering Contradiction:
Improveindependent network managementVSAvoidresource utilization efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent combines mobile communication and video broadcast networks into a single integrated TDM-FDM system managed by a central control node, achieving high resource utilization while maintaining operational simplicity through unified management rather than separate independent management

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal communication infrastructure where the same frequency spectrum and transmission facilities serve both mobile communication and video broadcast functions, allowing one system to perform multiple functions efficiently

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

3Loss of energy

If cell breathing method is used to dynamically adjust cell area, then frequency spectrum waste is reduced, but system complexity greatly increases due to user switching and resource allocation requirements

Engineering Contradiction:
Improvefrequency spectrum utilizationVSAvoidsystem complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent merges broadcast and communication functions into a unified TDM-FDM system where resource allocation is simplified through centralized control, achieving dynamic spectrum utilization without the complexity of cell breathing user switching mechanisms

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a central control node as an intermediary that manages time slot and frequency allocation for all base stations and broadcast towers, simplifying resource allocation decisions and reducing system complexity compared to distributed cell breathing control

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If base stations continuously operate to provide mobile communication service, then service availability is maintained, but power consumption increases when traffic is low

Engineering Contradiction:
Improveservice availabilityVSAvoidbase station power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements periodic time-division operation where base stations and broadcast towers alternately activate in different time slots according to traffic demand, allowing equipment to enter low-power states during idle periods while maintaining service availability through scheduled activation

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent enables dynamic power management where base station operation modes are adjusted in real-time based on traffic conditions, switching between active and sleeping states through centralized TDM control to optimize the balance between service availability and energy consumption

Inventive Principle:
Principle #15Dynamics
