Authentication Code Authority Management for Network Element Line Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, setting changes for line services become inconsistent when the data communication network (DCN) fails, preventing the transfer of control messages and authority transfer, which hinders the management and control of network elements (NEs) and leads to communication disconnection, especially in radio communication networks.
Innovation Solution
A communication system where a management apparatus generates an authentication code for each network element (NE) and notifies it to determine whether to accept changes to the line service settings, ensuring that only authorized changes are made, even during DCN failures, by using an authentication code-based authority management system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If control messages are transferred via DCN for authority management, then centralized management is achieved, but communication disconnection occurs during DCN failures
Solution Approach 1:
The authentication code is notified to the network element in advance before any setting change operations. This preliminary action stores the authorization information locally in the network element, so that even when DCN communication fails, the network element can still independently judge whether to accept setting changes based on the pre-stored authentication code, ensuring communication continuity during DCN failures.
2Ease of operation
If setting authority is freely distributed to multiple NMS and LCT, then operational flexibility is improved, but setting inconsistency occurs across the system
Solution Approach 1:
The authentication code acts as an intermediary mechanism between the management apparatus and network element. It provides a standardized authorization verification method that allows multiple NMS and LCT to operate flexibly while ensuring that only authenticated operations are executed, thereby maintaining setting consistency across the entire system despite distributed access.
Solution Approach 2:
The network element uses the authentication code to judge whether to accept setting changes, providing a feedback mechanism that verifies authorization before executing operations. This feedback loop ensures that any setting changes, regardless of which NMS or LCT initiates them, are properly authenticated and consistent with system-wide settings.
3Adaptability or versatility
If authority transfer function is implemented via DCN control messages, then setting authority can be transferred, but authority transfer fails during DCN failures
Solution Approach 1:
The authentication code is notified to the network element in advance before any setting change operations. This preliminary action stores the authorization information locally in the network element, so that even when DCN communication fails, the network element can still independently judge whether to accept setting changes based on the pre-stored authentication code, ensuring communication continuity during DCN failures.

AI summary
A communication system comprises a plurality of network elements and a management apparatus. Each of the network elements transfers a data signal. The management apparatus manages a line service provided by a network element as management object among the plurality of network elements. The management apparatus generates an authentication code corresponding to the network element as management object and notifies the generated authentication code to the network element as management object. The network element as management object, using the notified authentication code, judges whether or not to accept a change concerning the line service of the own network element.
