Reflective QoS Rule Management in User Equipment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks face challenges in managing Quality of Service (QoS) rules, particularly in switching between reflective and explicit QoS mechanisms, leading to inefficiencies in resource allocation and storage management for user equipment (UE).
Innovation Solution
A data transmission method and apparatus that allow user equipment to switch between reflective QoS activation and deactivation mechanisms, enabling flexible configuration and management of QoS rules by generating and deleting implicit and explicit QoS rules based on messages from the control and user plane network elements, thereby optimizing resource utilization and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the UE automatically generates implicit QoS rules based on downlink data in reflective QoS scenario, then signaling overhead is reduced and QoS management is simplified, but the UE cannot switch between reflective QoS activation and deactivation mechanisms when QoS policy changes
Solution Approach 1:
The patent introduces a dynamic switching mechanism between reflective QoS activation and deactivation states. The network can control the UE to switch between these states through downlink data packets with specific RQI field values, enabling the system to adapt to changing QoS policies while maintaining the benefits of reflective QoS when appropriate
2Adaptability or versatility
If the UE maintains multiple QoS rules (explicit and implicit) for different services, then QoS management flexibility is improved, but storage resources in the UE may become overloaded
Solution Approach 1:
The patent implements a mechanism where implicit QoS rules are automatically deleted when the reflective QoS deactivation mechanism is triggered. This allows the UE to release storage resources occupied by no longer needed QoS rules, preventing storage overload while maintaining the ability to generate new rules when reflective QoS is reactivated
Solution Approach 2:
The UE autonomously manages its QoS rule storage by automatically generating implicit rules when needed and automatically deleting them when the reflective QoS mechanism is deactivated, without requiring manual intervention or complex external management

AI summary
Embodiments of this application provide a data transmission method. The method includes: receiving, by user equipment, a first message, where the first message is used to instruct the user equipment to activate a reflective quality of service RQ mechanism; generating, by the user equipment, an implicit quality of service implicit QoS rule according to the RQ mechanism; receiving, by the user equipment, a second message, where the second message is used to instruct the user equipment to stop using the RQ mechanism; and stopping, by the user equipment, using the RQ mechanism, and deleting the implicit QoS rule. The user equipment receives the second message indicating that using of the RQ mechanism needs to be stopped, and deletes the implicit QoS rule, so as to implement switching between an explicit QoS rule and the implicit QoS rule, and flexibly configure a QoS rule for uplink data according to a policy of an operator. Moreover, a QoS rule stored and maintained in the UE can be effectively managed, and a storage resource can be released in a timely manner, thereby avoiding overload of storage space of the UE.
