Radio Core Layer Integration for QoS Flow Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network architectures, particularly in next-generation wireless networks, face challenges in resource utilization and quality of service (QoS) metrics due to unnecessary network resource usage and intermediary mapping in GTP-U tunnels, which negatively impact latency and overall performance.
Innovation Solution
A radio and core integrated layers service is implemented, where a user plane network device maps QoS flows directly into radio bearers without intermediary GTP-U tunnel mapping, utilizing PDU, SDAP, and PDCP functions, and determines service invocation based on collocation guidance information to optimize resource utilization and QoS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If QoS flows are mapped through GTP-U tunnels to radio bearers, then network compatibility and routing flexibility are maintained, but network resource utilization decreases and latency increases
Solution Approach 1:
The patent extracts and eliminates the GTP-U tunnel mapping intermediary from the QoS flow path. By removing this unnecessary intermediate mapping step, the system achieves direct mapping from QoS flows to radio bearers, reducing network resource consumption and eliminating the complexity associated with maintaining GTP-U tunnel mappings while preserving end-to-end connectivity.
Solution Approach 2:
The patent merges the QoS flow mapping function directly with the radio bearer allocation function. Instead of having separate GTP-U tunnel mapping and radio bearer mapping operations, the system combines these functions into a single direct mapping operation, reducing the number of processing steps and improving resource utilization efficiency.
2Loss of time
If GTP-U tunnel mapping is used for QoS flow routing, then core network routing flexibility is maintained, but latency increases due to unnecessary intermediary mapping
Solution Approach 1:
The patent extracts and removes the GTP-U tunnel mapping intermediary that causes latency. By eliminating this intermediate mapping step, data packets can be routed directly from QoS flows to radio bearers without the additional processing delay associated with GTP-U tunnel establishment and maintenance, while core network routing flexibility is preserved through alternative routing mechanisms.
3Productivity
If traditional separate radio and core layer mapping is used, then network architecture compatibility is maintained, but resource utilization and QoS performance deteriorate
Solution Approach 1:
The patent merges the radio access layer and core network layer mapping functions into a unified direct mapping mechanism. By combining these previously separate mapping operations into a single integrated process, the system eliminates the performance degradation associated with layered mapping while maintaining compatibility with existing network architectures through standardized interface definitions.

AI summary
A method, a device, and a non-transitory storage medium are described in which a radio and core integrated layers service is provided. The service provides a direct mapping of a quality of service flow between a packet data unit layer and a service data adaptation layer associated with a user plane function and a central unit-user plane function without an intermediary mapping of a tunneling protocol in the user plane.
