Dynamic RF Spectrum Allocation for Audio Video Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Base stations face challenges in efficiently transmitting audio and video packets over unlicensed and licensed RF spectrum bands due to network interference and resource consumption, which affects transmission performance and resource conservation.
Innovation Solution
Implementing a dynamic allocation system that allows base stations to allocate resources of unlicensed and licensed RF spectrum bands based on predefined rules, enabling the transmission of audio and video packets through the most suitable band to conserve resources and enhance performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If audio and video packets are transmitted via licensed RF spectrum band, then transmission reliability is improved, but network resource consumption increases
Solution Approach 1:
The patent segments the transmission of audio and video packets across two different RF spectrum bands (licensed and unlicensed). Video packets are transmitted via the licensed band for reliability, while audio packets are transmitted via the unlicensed band to conserve resources. This segmentation resolves the contradiction by distributing packets across different channels with different characteristics.
Solution Approach 2:
The patent applies local quality by assigning different transmission channels to different packet types based on their specific requirements. Video packets receive the higher-quality licensed band transmission, while audio packets use the unlicensed band. This differentiated approach optimizes resource consumption while maintaining acceptable transmission reliability for each packet type.
2Quantity of substance
If audio and video packets are transmitted via unlicensed RF spectrum band, then network resource consumption is reduced, but transmission reliability deteriorates due to network interference
Solution Approach 1:
The patent segments the transmission load between licensed and unlicensed bands, placing only audio packets (which are more tolerant of interference) on the unlicensed band. This segmentation allows the system to reduce overall network resource consumption while maintaining transmission reliability for critical video data through the licensed band.
Solution Approach 2:
The licensed RF spectrum band acts as an intermediary for video packets that require high reliability, while the unlicensed band serves as a supplementary channel for audio packets. This intermediary approach allows the system to leverage the strengths of both bands without forcing all traffic through the more resource-intensive licensed band.
3Productivity
If dynamic allocation system is implemented, then transmission performance is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic allocation by enabling the base station to flexibly assign audio and video packets to different RF spectrum bands based on current network conditions, packet priorities, and resource availability. This dynamic approach improves transmission performance by adapting to changing conditions, while the complexity is managed through automated base station control rather than manual configuration.
