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 issues.
Innovation Solution
A method and apparatus for path resource adjustment that involves network elements detecting faults and sending alarms to a management control unit, which then issues commands for withdraw processing to ensure resource matching by rolling back or canceling adjustments.
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
Solution Approach 1:
The patent implements a feedback mechanism where network elements monitor the status of resource adjustment operations and report to the management control unit. When a fault is detected during bandwidth adjustment, the system receives feedback about the failed operation and triggers a rollback to the previous stable state, thus maintaining reliability while preserving adaptability for future adjustments.
Solution Approach 2:
The patent applies beforehand cushioning by implementing a fault detection and rollback mechanism that prepares compensatory measures in advance. Before performing resource adjustment, the system establishes a safety mechanism that can revert to the previous state if adjustments fail, thus cushioning against potential reliability issues while enabling adaptive resource changes.
2Adaptability or versatility
If resource adjustment is performed across multiple network elements in a communication path, then adaptability is improved, but device complexity increases due to coordination requirements
Solution Approach 1:
The patent introduces a management control unit as an intermediary that coordinates resource adjustments across multiple network elements. This centralized mediator receives adjustment requests, formulates coordinated commands for all involved network elements, and manages the overall adjustment process, thereby enabling path-level resource flexibility without requiring complex peer-to-peer coordination between individual network elements.
Solution Approach 2:
The patent applies segmentation by dividing the resource adjustment function into separate components: the management control unit handles high-level coordination and decision-making, while individual network elements execute specific local adjustments. This segmentation allows the system to achieve complex path resource flexibility through simple, modular operations at each network element level.
3Reliability
If fault detection mechanism is implemented to monitor resource adjustment status, then reliability is improved, but loss of time increases due to monitoring overhead
Solution Approach 1:
The patent implements continuity of useful action by having network elements continuously monitor the status of resource adjustment operations as part of their normal operation. Rather than performing separate detection steps that would add time overhead, the monitoring is integrated into the continuous operation of the network elements, allowing fault detection without significant additional time cost while maintaining high reliability.

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.
