Transmission Device Dynamic Bit Rate Adjustment for Multicast Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of reception devices in a multicast communication network increases, the allocated communication band is determined based on the number of devices, leading to network congestion due to increased data transfer, which existing technologies fail to effectively manage.
Innovation Solution
A transmission device and system that specify the number of reception devices, determine a reduced data size or bit rate based on the number of devices, and generate communication data accordingly to transmit it efficiently, thereby reducing network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the communication band is determined according to the number of reception devices participating in the multicast group, then the data transfer capacity increases to accommodate more devices, but the network load increases causing congestion
Solution Approach 1:
The patent changes the parameter of communication band allocation from being proportional to the number of reception devices to being dynamically adjusted based on actual network conditions and device requirements. Each reception device receives an individually optimized communication band rather than a uniform allocation, allowing the system to accommodate more devices without linearly increasing total network load.
2Adaptability or versatility
If more reception devices are served with the same data quality, then user satisfaction is maintained, but the communication network becomes congested
Solution Approach 1:
The patent applies local quality by assigning different communication bands to different reception devices based on their individual characteristics, device types, and network conditions. Instead of uniform data quality for all devices, each device receives an optimized communication band tailored to its specific requirements, allowing the system to serve more devices without causing network congestion.
3Speed
If the communication band is allocated based on maximum communication band of the cell, then individual device performance is optimized, but overall network efficiency decreases when multiple devices are served
Solution Approach 1:
The patent introduces dynamics by making the communication band allocation flexible and adaptive rather than static. The allocation changes based on real-time network conditions, device requirements, and traffic patterns, allowing the system to optimize both individual device performance and overall network efficiency simultaneously through continuous adjustment.

AI summary
A transmission device is a transmission device that transmits communication data to one or more reception devices via a network. A transmission device includes: a specification unit that specifies a reception device number indicating the number of the reception devices that are a destination of communication data; a determination unit that, in a case where the reception device number is a first number, determines a data size or a bit rate of the communication data such that the data size or the bit rate becomes smaller or lower than that in a case where the reception device number is a second number smaller than the first number; a generation unit that generates the communication data by using the determined data size or bit rate; and a transmission unit that transmits the generated communication data to one or more reception devices that are the destination via the network.
