Data Rate Control Method Using Dynamic Class Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network architectures face challenges in dynamically adjusting maximum data rates to match varying available radio resources for user equipment (UE) across different radio access technologies and spectrum types, which can lead to suboptimal throughput and quality of service (QoS) maintenance.
Innovation Solution
A data rate modification method that allows the eNB to autonomously adjust maximum data rates for both RAN and CN by classifying data rates into multiple classes based on available radio resources, considering UE preferences and statistical information, and reporting traffic volume to the core network, ensuring seamless adaptation to changes in radio resource availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the maximum data rate is fixed based on authorized QoS parameters, then QoS can be maintained, but throughput becomes suboptimal when radio resources vary
Solution Approach 1:
The patent implements dynamic data rate adjustment by introducing multiple data rate classes (first class, second class, etc.) that can be switched based on radio resource conditions. The eNB autonomously modifies the maximum data rate from a first data rate class to a second data rate class when radio resources become unavailable, enabling the system to adapt to varying channel conditions while maintaining QoS through controlled rate adjustments.
2Productivity
If frequent data rate adjustments are made to match radio resource variations, then throughput is optimized, but signaling storms may occur
Solution Approach 1:
The eNB is empowered with autonomous authority to modify the maximum data rate without requiring core network involvement for each adjustment. The eNB can independently switch between data rate classes based on local radio resource conditions, eliminating the need for frequent signaling to the core network and avoiding signaling storms while maintaining optimized throughput.
3Adaptability or versatility
If the eNB autonomously adjusts data rates, then adaptation to radio resource changes is seamless, but control over maximum data rate is reduced
Solution Approach 1:
The patent segments the data rate control into discrete classes (first data rate class, second data rate class, etc.), each with specific maximum data rates. The eNB autonomously selects among these pre-defined classes based on radio resource availability, providing seamless adaptation while maintaining operational control through the structured class-based framework.

AI summary
The disclosure is directed to a data rate modification method and related apparatuses using the same method. According to one of the exemplary embodiment, the disclosure is directed to a data rate control method implemented by a user equipment, the method would include not limited to: transmitting a connection establishment message which comprises an identification (ID) of the UE and a network ID; receiving a data rate configuration comprising a first data rate class ID and a plurality of network data rates which is associated with the network ID as each network data rate is associated with a different data rate class ID; and setting a first data rate based on the first data rate class ID to communicate with a core network
