Base Station OMCH Reconnection Using Historical Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communications networks, the interruption of the operation and management channel (OMCH) between a base station and an OSS server leads to difficulties in remote operation and management, requiring extensive human resources for onsite resolution, as the base station often cannot reestablish the connection due to a lack of required channel establishment parameters.
Innovation Solution
The base station obtains and stores historical channel establishment parameters to reestablish the OMCH when interrupted, using these parameters to reconnect with the OSS server, either by initializing the base station or broadcasting a DHCP probe message to retrieve necessary configuration data.

Engineering Contradiction Analysis
1Reliability
If the base station uses traditional channel establishment methods without storing historical parameters, then the device complexity is reduced, but the reliability of OMCH connection is worsened when interruptions occur
Solution Approach 1:
The base station performs preliminary actions by storing historical channel establishment parameters (such as IP addresses, port numbers, and protocol configurations) before OMCH interruption occurs. When the OMCH is interrupted, the base station can immediately retrieve these pre-stored parameters to reestablish the connection, eliminating the need for complex real-time negotiation and improving connection reliability without significantly increasing device complexity
Solution Approach 2:
The base station creates a copy of the channel establishment parameters from previous successful connections and stores them locally. This copied parameter set serves as a backup that can be rapidly deployed when the OMCH is interrupted, allowing the base station to restore connectivity quickly without needing to re-negotiate all connection parameters, thus improving reliability while keeping the system relatively simple
2Productivity
If the base station automatically reestablishes OMCH connection using historical parameters, then human resource consumption is reduced, but the risk of connection errors increases
Solution Approach 1:
The base station implements a feedback mechanism where it attempts to reestablish the OMCH connection using historical parameters, then monitors whether the reestablished connection is successful. If the connection fails or errors occur, the system feedback indicates this to the base station, which can then adjust its parameters or attempt alternative connection methods. This closed-loop feedback ensures high automation efficiency while maintaining connection accuracy through continuous validation
Solution Approach 2:
Before automatically reestablishing the connection using historical parameters, the base station performs preliminary validation checks on these parameters to ensure they are still valid and appropriate for current network conditions. This preliminary anti-action prevents the use of outdated or incorrect parameters, reducing the risk of connection errors while maintaining automation efficiency

AI summary
This application relates to the field of communications technologies, and more specifically, to a technology for establishing an operation and management channel. In a channel establishment method, a base station obtains a connection status of an operation and management channel between a base station and an operation support system OSS server. If the connection status indicates that there is a connection exception on the operation and management channel, the base station obtains a historical channel establishment parameter that is stored in the base station before a current moment and that is used by the base station to establish the operation and management channel with the OSS server. In this way, the connection of the operation and management channel between the base station and the OSS server may be successfully established by using the historical channel establishment parameter that is used by the base station to successfully establish the operation and management channel with the OSS server before the current moment, so that when there is an exception on the operation and management channel between the base station and the OSS server, this also ensures reliable establishment of the operation and management channel between the base station and the OSS server, and improves reliability and stability of the operation and management channel between the base station and the OSS server.
