End-to-End QoS Splitting Across PC5 and Uu Communication Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems only consider network-side device-generated QoS requirements, limiting application scenarios that satisfy end-to-end quality of service (QoS) requirements.
Innovation Solution
The method involves splitting end-to-end QoS requirement information into PC5-segment and Uu-segment QoS information, which can be performed by target devices such as UE, access network devices, or core network devices, using predefined mapping relationships to ensure accurate radio resource allocation and satisfy end-to-end QoS guarantees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If only network-side device-generated QoS requirements are considered, then the QoS control process is simple, but the application scenarios that satisfy QoS requirements are limited
Solution Approach 1:
The patent segments the end-to-end QoS requirement information into two distinct parts: PC5-segment QoS information (for the direct communication link between UEs) and Uu-segment QoS information (for the network link). This segmentation allows each segment to be optimized independently for its specific communication scenario, thereby expanding applicable scenarios while maintaining manageable complexity through dedicated processing for each segment type.
2Measurement precision
If end-to-end QoS requirement information is transmitted directly without splitting, then the signaling overhead is low, but the QoS guarantees across indirect communication links are inaccurate
Solution Approach 1:
By dividing the QoS requirement information into PC5-segment and Uu-segment components, the patent enables precise QoS control for each communication link type. The PC5-segment QoS information specifically addresses the direct UE-to-UE link characteristics, while Uu-segment QoS information addresses the network link characteristics, ensuring accurate QoS guarantees tailored to each segment's requirements.
Solution Approach 2:
The patent applies local quality by configuring different QoS parameters and attributes specific to each communication segment. The PC5-segment QoS information includes parameters optimized for direct device-to-device communication, while Uu-segment QoS information includes parameters optimized for network infrastructure communication, ensuring each segment receives appropriately tailored QoS treatment.
3Reliability
If the relay UE converts Uu-segment QoS information to PC5-se段 QoS parameter based on mapping relationship, then the end-to-end QoS requirement is satisfied, but the signaling overhead increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring mapping relationships between Uu-segment QoS information and PC5-segment QoS parameters through the network. This allows the relay UE to perform efficient conversion without complex real-time calculations, ensuring reliable end-to-end QoS satisfaction while minimizing signaling overhead through streamlined conversion processes.
