Adaptive QoS for Latency-Sensitive Cellular Applications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless user equipment (UE) devices often lack flexibility in determining and adjusting the quality of service (QoS) configuration for latency-sensitive applications, leading to inadequate communication quality and poor user experience due to insufficient QoS settings in current wireless communication standards.
Innovation Solution
The UE device establishes a 'pipeline' or bearer with the cellular network and determines eligibility for an enhanced QoS configuration, transmitting requested QoS parameters such as target latency and jitter to adjust the bearer settings dynamically, with periodic measurements to inform network adjustments and maintain optimal QoS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE uses standard wireless communication protocols without enhanced QoS configuration, then the device complexity remains low and ease of operation is maintained, but the quality of service for latency-sensitive applications becomes inadequate
Solution Approach 1:
The patent implements dynamic QoS configuration where the UE can actively adjust bearer parameters based on application needs. The system transitions from static default QoS to dynamic adaptive QoS through mechanisms like QoS enhancement requests, bearer modification, and periodic QoS measurements that enable real-time optimization of latency-sensitive communications.
Solution Approach 2:
The patent changes key QoS parameters including latency, jitter, and packet loss thresholds to optimize application performance. By modifying bearer parameters such as packet delay budget, packet error loss rate, and priority levels, the system adapts the communication quality to match the specific requirements of latency-sensitive applications.
2Reliability
If the UE dynamically adjusts QoS configuration parameters, then the quality of service improves for latency-sensitive applications, but the device complexity and operational difficulty increase
Solution Approach 1:
The patent enables the UE to autonomously manage its own QoS configuration through self-service mechanisms. The UE automatically determines when QoS enhancement is needed, selects appropriate parameters, sends enhancement requests to the network, and monitors performance through periodic measurements without requiring manual user intervention or complex external configuration.
Solution Approach 2:
The patent implements feedback loops where the UE periodically measures actual QoS parameters (latency, jitter, packet loss) and uses this information to determine whether QoS enhancement is needed. This feedback mechanism allows the system to automatically adjust configurations based on real-time performance data, making the process transparent and automated.
3Adaptability or versatility
If the UE performs periodic QoS measurements and network adjustments, then the adaptability and responsiveness of the system improve, but the loss of time for measurement and adjustment increases
Solution Approach 1:
The patent uses periodic QoS measurements at configured intervals to monitor network conditions and application performance. By performing measurements at regular intervals rather than continuously, the system achieves adaptability while reducing the time overhead associated with constant monitoring and adjustment.
Solution Approach 2:
The patent performs QoS measurements and eligibility determinations in advance before full QoS enhancement is activated. The UE periodically checks whether it meets criteria for enhanced QoS and prepares adjustment requests beforehand, allowing for more efficient real-time adjustments when needed.

AI summary
Embodiments are presented herein of apparatuses, systems, and methods for a user equipment (UE) device to adaptively enhance the quality of service (QoS) configuration of a bearer of communications conducted over a cellular network between a UE application and a server. The UE may use various information, including a QoS profile associated with the application, to determine requested QoS parameters and/or whether the UE is permitted to request or access enhanced QoS functionality. The UE may then send a request to the cellular network indicating the requested QoS parameters, and the network may adjust the QoS configuration of the bearer in response. The UE and the network may perform routine QoS measurements and exchange information in order to adaptively maintain and optimize the QoS configuration. These techniques may tend to provide more appropriate QoS to the application, which may improve user experience.
