CPE Instance Label Mapping via SearchLabel RPC and Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current device management and automatic configuration frameworks for CPEs in DSL networks face challenges in determining instance label mappings, leading to reduced configuration success ratios due to inability to verify index labels and manage deleted object instances.
Innovation Solution
Implementing a method and apparatus that allow managing devices to send SearchLabel Requests and receive corresponding instance label information, and managed devices to send LabelDeletion Notifications, enabling accurate mapping and notification of deleted instances, thus improving configuration success ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the ACS uses index labels to manage object instances on CPEs, then the ACS can uniformly manage the same object instance on multiple CPEs, but the ACS cannot determine whether a specific index label corresponds to an instance label stored on the CPE or detect when object instances are deleted
Solution Approach 1:
The CPE actively reports instance label information to the ACS through event notifications (such as LabelDeleted events). This feedback mechanism allows the ACS to obtain real-time information about instance labels and their mappings without having to query each CPE individually, thus resolving the information loss problem while maintaining uniform management capability
Solution Approach 2:
The CPE pre-stores and maintains the mapping relationships between index labels and instance labels locally. When an object instance is created or deleted, the CPE proactively reports these changes to the ACS before the ACS needs to perform batch configuration, ensuring the ACS has accurate information available when needed
2Measurement precision
If the CPE stores mapping relationships between index labels and instance labels, then the CPE can maintain local mapping information, but the ACS fails to perform batch configuration on deleted object instances, reducing configuration success ratio
Solution Approach 1:
The CPE sends event notifications (e.g., LabelDeleted events) to the ACS when object instances are created, modified, or deleted. This real-time feedback ensures the ACS has accurate information about the current state of object instances on the CPE, allowing the ACS to verify whether target object instances exist before performing batch configuration operations, thereby preventing failures on deleted instances
Solution Approach 2:
The CPE autonomously monitors its own object instances and proactively reports changes to the ACS without requiring ACS to query or poll the CPE. This self-service approach ensures the CPE maintains accurate local mapping information and communicates changes immediately, improving the reliability of subsequent ACS configuration operations

AI summary
The present invention relates to the field of communication technologies, and discloses a method and an apparatus for obtaining and reporting instance label information and a system for processing instance label information. The method includes the following steps: a managing device sends a SearchLabel Request, where the Request carries information of an index label and the index label is used by the managing device for citing an object instance; the managing device receives a SearchLabel Response, where the Response carries information of an instance label corresponding to the index label information and the instance label is used by a managed device for citing the object instance. According to the present invention, the managing device calls the SearchLabel RPC method to search the managed device for the mapping relationships between index labels and instance labels, so that the managing device can obtain information of the mapping relationships of index labels on the managed device, thus improving the success ratio of configuration.
