Solution Overview

Problem

Current communication systems, such as WCDMA, face ambiguities and errors in processing physical shared channel reconfiguration requests due to unclear interpretations of information elements, leading to misinterpretations and inability to delete priority queues or reconfigure transport bearers as instructed, resulting in communication errors.

Innovation Solution

A message processing method and system that includes receiving specific deleting information for priority queues and transport bearers, allowing for their deletion or reconfiguration as needed, and determining the existence of medium access control flows to handle reconfiguration requests accurately, thereby clarifying the processing of physical shared channel reconfiguration requests.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the NodeB interprets the IE of 'common MAC flow specific information' as both newly established and reconfigured, then the reconfiguration request can be processed, but the processing becomes ambiguous and errors occur

Engineering Contradiction:
Improvereconfiguration capabilityVSAvoidprocessing accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the ambiguous IE interpretation into distinct cases by introducing a determination step that checks whether the medium access control flow exists. This segmentation resolves the ambiguity by creating clear decision branches: if the flow exists, perform reconfiguration; if not, perform new establishment. This eliminates the problematic 'both newly established and reconfigured' interpretation mode.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Instead of trying to make the IE serve dual purposes simultaneously (which causes ambiguity), the patent inverts the approach by using the existence check to determine the single correct interpretation mode. The logic is inverted from 'try to do both' to 'determine which one to do based on flow existence', thereby resolving the contradiction between adaptability and reliability.

Inventive Principle:
Principle #13The other way round (Inversion)

2Adaptability or versatility

If the NodeB does not know how to specifically process after receiving the relevant IE, then the system maintains flexibility in interpretation, but communication errors occur

Engineering Contradiction:
Improveinterpretation flexibilityVSAvoidcommunication accuracy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by performing an existence determination of the medium access control flow before executing the reconfiguration or new establishment. This preliminary check establishes a clear processing path based on the flow's existence status, eliminating the uncertainty and flexibility that lead to errors while maintaining appropriate adaptability through conditional processing.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If the priority queue under the same medium access control flow can only be added and not subtracted, then the system maintains simplicity, but the NodeB cannot delete priority queues as required

Engineering Contradiction:
Improvesystem simplicityVSAvoidpriority queue management capability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent makes the priority queue management dynamic by introducing conditional logic that adapts the operation type (new establishment vs. reconfiguration) based on the existence of the medium access control flow. This dynamic approach enables the system to both add and effectively remove (through reconfiguration) priority queues, enhancing adaptability while maintaining reasonable system complexity through unified processing logic.

Inventive Principle:
Principle #15Dynamics

4Device complexity

If the transport bearer is not reestablished during medium access control flow reconfiguration, then the processing is simpler, but the transport bearer configuration cannot be updated as instructed

Engineering Contradiction:
Improvereconfiguration complexityVSAvoidconfiguration accuracy
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent introduces feedback by checking the transport bearer request indicator information and using this feedback to determine whether to reestablish the transport bearer. This feedback mechanism ensures that the transport bearer configuration is updated when required by the reconfiguration request, maintaining configuration accuracy while avoiding unnecessary reestablishment operations that would increase complexity.

Inventive Principle:
Principle #23Feedback

AI summary

A message processing method includes receiving by a base station a physical shared channel reconfiguration request transmitted from a control radio network controller, the physical shared channel reconfiguration request including priority queue specific deleting information; and deleting a priority queue corresponding to the priority queue specific deleting information.
