Statistical Multiplexing of Radio Bearers for Resource Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multimedia broadcast multicast services, radio bearers are often provisioned with fixed bandwidth based on peak bitrate to ensure high-quality user experience, leading to wastage of resources when network traffic is below peak levels, as additional allocated bandwidth cannot be utilized by other traffic.
Innovation Solution
The solution involves multiplexing multiple radio bearers to form a master bearer with a bandwidth less than the sum of their peak bitrates, using statistical techniques to allocate bandwidth based on average or varying bitrates, thereby conserving radio resources by efficiently reallocating bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio bearers are provisioned with fixed bandwidth based on peak bitrate to ensure high-quality user experience, then service quality is improved, but resource waste increases when network traffic is below peak levels
Solution Approach 1:
The patent applies dynamics by transitioning from static fixed bandwidth allocation to dynamic bandwidth allocation. The system continuously monitors actual network traffic and adjusts the bandwidth of radio bearers in real-time, allowing the allocation to adapt between peak and non-peak periods. This resolves the contradiction by maintaining high service quality during peak traffic while reducing resource waste during low traffic periods.
Solution Approach 2:
The patent changes the bandwidth parameter of radio bearers based on actual traffic conditions. Instead of keeping bandwidth fixed at peak levels, the system modifies the bandwidth parameter dynamically according to measured traffic patterns. This parameter change enables the system to maintain service quality when needed while conserving resources when traffic is lower.
2Productivity
If multiple radio bearers are multiplexed to conserve resources, then resource efficiency is improved, but system complexity increases
Solution Approach 1:
The patent merges multiple individual radio bearers into a single multiplexed bearer structure. By combining several bearers that would otherwise operate separately into one unified bearer, the system improves resource efficiency through better utilization of available bandwidth while managing complexity through a standardized multiplexing framework.
Solution Approach 2:
The patent creates a universal multiplexing mechanism that can handle multiple different radio bearers through a single standardized process. The multiplexed bearer serves multiple functions by carrying traffic from multiple original bearers, allowing the system to improve resource efficiency without proportionally increasing complexity through specialized handling for each bearer type.
