Solution Overview

Problem

Current wireless communication systems face challenges in efficiently updating quality of service (QoS) information when devices using different radio access technologies, such as 5G NR and LTE, coexist, leading to unintended impacts on QoS configurations and potential errors in bearer context modifications.

Innovation Solution

The method involves receiving QoS information and associated identifiers from a network entity, and updating QoS configurations based on whether the user equipment (UE) is already configured with different QoS information for a bearer context, using a QoS parameter updating module to manage mappings between 5G System (5GS) and Evolved Packet System (EPS) QoS parameters, ensuring accurate application of QoS rules and flow descriptions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If QoS information is updated without checking existing configurations, then QoS parameter updates can be applied quickly, but unintended impacts on existing bearer contexts and QoS configurations occur

Engineering Contradiction:
ImproveQoS parameter update speedVSAvoidQoS configuration accuracy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary action by checking whether QoS information associated with a QoS identifier is already configured for a different bearer context before performing the update operation. This pre-check prevents unintended impacts on existing configurations while allowing quick updates when no conflict exists, thus resolving the contradiction between update speed and configuration accuracy

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If QoS information is mapped between 5GS and EPS without validation, then interoperability between radio access technologies is achieved, but errors in bearer context modifications occur

Engineering Contradiction:
ImproveMulti-technology compatibilityVSAvoidBearer context modification accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements feedback by validating the mapped QoS information from 5GS to EPS against existing bearer context configurations. The system checks whether the QoS identifier already exists in a different bearer context and provides feedback to prevent erroneous modifications, thus maintaining both multi-technology compatibility and modification accuracy

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If comprehensive validation of QoS information is performed before updates, then configuration accuracy is improved, but processing time increases

Engineering Contradiction:
ImproveQoS configuration precisionVSAvoidQoS parameter processing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies partial action by performing only the necessary validation check - verifying whether QoS information associated with the QoS identifier is already configured for a different bearer context. This selective validation achieves sufficient configuration precision without requiring exhaustive validation of all QoS parameters, thus minimizing processing time while maintaining accuracy

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for updating QoS configurations at a user equipment (UE). An example method generally includes receiving, from a network entity, quality of service (QoS) information, a QoS identifier associated with the QoS information, and a bearer context associated with the QoS information in one of a modify bearer context request message, an activate default bearer context request message, or an activate dedicated bearer context request message; and updating a QoS configuration using the QoS information based on whether the UE is already configured with QoS information associated with the QoS identifier for a bearer context different from the bearer context associated with the QoS information received in the modify bearer context request message, activate default bearer context request message, or activate dedicated bearer context request message.
