Communication Channel Resource Rollback for Adjustment Faults
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies lack an effective mechanism to handle path resource adjustment faults, such as network or device failures, leading to potential path resource mismatches and transmission failures.
Innovation Solution
A method and apparatus where a management control unit sends a command to network elements to withdraw resource adjustments upon detecting a fault, ensuring each network element maintains its original resources, thereby maintaining resource matching and preventing transmission failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If path resource adjustment is performed online to meet changing bandwidth requirements, then adaptability is improved, but reliability deteriorates due to potential adjustment faults causing resource mismatch
Solution Approach 1:
The patent implements a feedback mechanism where network elements monitor the completion status of resource adjustment commands. When a fault is detected (indicated by alarm information), the system automatically triggers a rollback command to revert resources to their original state, ensuring reliability while maintaining adaptability for online adjustments.
Solution Approach 2:
The patent prepares for potential adjustment failures by establishing a fault handling mechanism in advance. Before committing to resource adjustments, the system has pre-configured rollback capabilities that automatically activate upon detecting adjustment faults, cushioning against the reliability risks of online bandwidth adjustments.
2Productivity
If resource adjustment commands are issued to network elements, then productivity is improved through faster bandwidth adjustment, but device complexity increases due to fault handling mechanisms
Solution Approach 1:
The patent enables network elements to automatically detect and handle their own adjustment faults without requiring complex external intervention. Each network element monitors its own adjustment status and can autonomously trigger rollback operations, reducing the overall system complexity while maintaining fast adjustment capabilities.
3Device complexity
If resource adjustment is performed without fault handling mechanism, then device complexity is reduced, but loss of information occurs due to resource mismatch
Solution Approach 1:
The patent uses feedback from network elements about adjustment completion status to detect resource mismatches. When inconsistency is detected, the system automatically initiates rollback commands to restore consistent resource states across all network elements, preventing information loss while maintaining system simplicity.

AI summary
The present disclosure relates to the technical field of communications. Disclosed are a channel resource adjustment method and apparatus, and a communication device, which are used for solving the problem in the prior art of lacking an effective processing mechanism for a channel resource adjustment abnormality. The method comprises: after detecting that a resource adjustment abnormality occurs in a communication channel, a first network element sending alarm information to a management control unit, wherein the first network element is any one of a plurality of network elements in the communication channel; the management control unit sending to each of the plurality of network elements a command, which is used for indicating the revocation of resource adjustment; and each of the plurality of network elements performing revocation processing on its own resource adjustment on the basis of the command. In this way, an effective processing mechanism is provided for an abnormality occurring in the resource adjustment of a communication channel; and by means of a management control unit issuing to network elements in the communication channel a command, which indicates the revocation of a resource adjustment, the network elements in the communication channel are prompted to revoke the present resource adjustment, such that resource matching between the network elements in the communication channel is ensured.
