UE QoS Guarantee via URSP Policy in LTE Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In regions without 5G connectivity, providing a dedicated communication level to user equipment (UE) that enables services like Automated Valet Parking (AVP) is challenging, as legacy areas often rely on LTE cores that do not support network slicing and UE Route Selection Policy (URSP).
Innovation Solution
A method where the UE dynamically checks available communication options (5G SA, 5G NSA, LTE) and, if 5G SA or NWS is unavailable, uses an API interface to communicate required Quality of Service (QoS) values to the LTE core or 5G SA core without NWS support, allowing the network to adjust resources accordingly to mimic slicing behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 5G SA with network slicing is deployed, then dedicated QoS guarantees can be provided to UE, but network complexity and deployment difficulty increase
Solution Approach 1:
The patent segments the QoS guarantee mechanism into two parts: the policy definition (URSP rules) is separated from the resource allocation (network slicing). This allows URSP to provide QoS guarantees through policy-based routing without requiring full network slicing deployment, thus reducing complexity while maintaining reliability
Solution Approach 2:
The patent makes the URSP mechanism universal by enabling it to provide QoS guarantees in both 5G SA with network slicing and 5G NSA/LTE environments. The same URSP policy framework can adapt to different network architectures, eliminating the need for separate solutions for different deployment scenarios
2Adaptability or versatility
If 5G NSA or LTE is used in legacy areas, then network coverage and compatibility are improved, but dedicated QoS guarantees cannot be provided
Solution Approach 1:
The patent changes the QoS parameter provisioning approach by introducing URSP policies that dynamically adjust QoS parameters (5QI, QCI, ARP) based on service requirements. This allows LTE and 5G NSA networks to provide dedicated QoS guarantees through policy-based parameter adjustment rather than requiring network slicing infrastructure
3Reliability
If URSP and network slicing are deployed together, then service-specific QoS can be guaranteed, but implementation complexity and resource overhead increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring URSP policies with service-specific QoS requirements before actual data transmission. The UE receives and stores URSP rules that contain 5QI, QCI, and ARP parameters for different service types, enabling immediate QoS application without real-time complex negotiations
Solution Approach 2:
The patent introduces the URSP policy as an intermediary layer between the application layer and the network resource allocation. The URSP rules act as a mediator that translates service requirements into network QoS parameters, simplifying the interaction between applications and the core network while maintaining service-specific QoS guarantees
