WTRU Media Flow QoS Rule Handling for Uplink Flow ID Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently processing supplemental Quality of Service (QoS) rules, particularly in determining the appropriate QoS flow ID for data packets based on multiple QoS rules with different stream ID values, leading to inefficiencies in network resource allocation.
Innovation Solution
A wireless transmit/receive unit (WTRU) processes supplemental QoS rules by receiving messages with multiple QoS rule Information Elements (IEs) and determining the uplink QoS flow ID based on packet filters and precedence rules, enabling it to send messages indicating supported QoS rules to network nodes.

Engineering Contradiction Analysis
1Productivity
If multiple QoS rules with different stream ID values are processed, then network resource allocation efficiency is improved, but the complexity of determining the appropriate QoS flow ID increases
Solution Approach 1:
The patent segments the QoS rule processing into distinct components: packet filter evaluation, stream ID extraction, and QoS flow ID determination. By breaking down the complex determination process into separate evaluation stages based on packet filters and stream identifiers, the system manages complexity while improving resource allocation efficiency.
Solution Approach 2:
The patent applies preliminary action by pre-evaluating packet filters and extracting stream IDs before final QoS flow ID determination. The system prepares packet filter matches and stream ID mappings in advance, enabling faster QoS flow ID selection during data packet processing and improving overall processing efficiency.
2Productivity
If packet filters and stream ID values are evaluated for multiple QoS rules, then data transmission optimization is improved, but processing time increases
Solution Approach 1:
The system performs preliminary evaluation of packet filters and extraction of stream IDs before final QoS flow ID determination. By pre-processing these components, the system reduces the time required for QoS flow ID selection during actual data packet processing, optimizing data transmission while minimizing processing delays.
Solution Approach 2:
The patent implements feedback mechanisms where the evaluated packet filter results and stream ID mappings are fed back into the QoS flow ID determination process. This feedback loop enables the system to use previously evaluated information to accelerate subsequent QoS flow ID selections, reducing processing time while maintaining optimization.
3Productivity
If supplemental QoS rules are implemented, then network resource allocation is optimized, but the complexity of processing QoS rules increases
Solution Approach 1:
The patent segments QoS rule processing into distinct components: packet filter evaluation, stream ID extraction, and QoS flow ID determination. By breaking down the complex determination process into separate evaluation stages based on packet filters and stream identifiers, the system manages complexity while improving resource allocation efficiency.
Solution Approach 2:
The patent creates a universal QoS rule processing framework that handles both default and supplemental QoS rules through the same packet filter evaluation and stream ID extraction mechanisms. This multi-functional approach simplifies processing complexity by using a single unified method for different QoS rule types while maintaining optimization capabilities.

AI summary
Systems, methods, devices, and instrumentalities described herein may be used to process and/or provide supplemental QoS rules. A first message may be received from a first network node. The first message may comprises a first Quality of Service (QOS) rule Information Element (IE) and a second QoS rule IE. The first QoS rule IE may be associated with a first QoS rule. The second QoS rule IE may be associated with a second QoS rule. A data packet to be sent to a second network node may be determined. An uplink QoS flow identification (ID) associated with the data packet may be determined based on at least one of the first QoS rule or the second QoS rule. A second message may be sent to a second network node. The second message may comprise the data packet and may indicate the uplink QoS flow ID.
