Wireless Network Core Dynamic Data Rate Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless network cores overallocate resources by not efficiently controlling backhaul data rates for user devices based on actual data rates, which vary due to network conditions and user activity, leading to suboptimal resource utilization.
Innovation Solution
The wireless network core determines dynamic data rates for user equipment by analyzing historical data rates and serving radio bands, adjusting data rates based on increased or decreased capacity and usage, thereby reducing resource overallocation and improving backhaul data rate management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless network cores allocate resources at maximum AMBR levels, then user data service capacity is improved, but resource overallocation occurs and utilization efficiency deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where the wireless network core continuously monitors actual data rates experienced by user devices and uses this information to dynamically adjust resource allocation. The core compares actual data rates with allocated AMBR levels and modifies future allocations based on observed usage patterns, preventing both overallocation and underallocation of network resources.
Solution Approach 2:
The patent transitions from static AMBR allocation to dynamic data rate control. The network core continuously adapts data rate allocations based on real-time network conditions, user activity patterns, and historical data rate information. This dynamic adjustment allows the system to optimize resource utilization by matching allocations to actual demand rather than maintaining fixed maximum levels.
2Ease of operation
If wireless network cores use static AMBR allocation, then resource management simplicity is improved, but adaptability to actual data rates deteriorates
Solution Approach 1:
The patent uses historical data rate information to predict future data rate requirements and pre-adjusts resource allocations accordingly. By analyzing past usage patterns and network conditions, the system proactively configures AMBR levels before actual data transmission occurs, enabling adaptive resource management while maintaining relatively simple operational procedures.
Solution Approach 2:
The system enables the network core to automatically adjust data rate allocations based on monitored actual data rates and network conditions, without requiring manual intervention. The core self-regulates resource distribution by comparing allocated rates with actual usage and autonomously modifying future allocations to optimize both simplicity and adaptability.

AI summary
In a wireless communication network, a wireless network core and wireless access nodes exchange user data using data rates. The wireless access nodes wirelessly exchange the data with the wireless UE over radio bands. The wireless network core determines a data rate level for the wireless UE based on the data rates. Subsequently, the wireless network core identifies a serving wireless access node and a serving radio band. The wireless network core determines a new data rate based on the data rate level and the serving radio band. The wireless network core and the serving wireless access node exchange new data using the new data rate. The serving wireless access node wirelessly exchanges the new data with the wireless UE over the serving radio band.
