Base Station Synchronization Channel Control for Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, halting or changing base station device information, such as cell IDs, during low communication traffic times is necessary but often results in communication disconnection or handover failure due to synchronization issues with mobile station devices.
Innovation Solution
A base station device controls the generation of synchronization channel signals to prevent new connections and changes base station information while notifying mobile stations of updates, allowing for halting or changing base station information without disrupting communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the base station device is halted or base station device information such as cell ID is changed, then maintenance and management tasks can be performed, but communication disconnection or handover failure occurs in the mobile station device
Solution Approach 1:
The base station transmits information about upcoming changes (cell ID, synchronization information) to mobile stations in advance before actually performing the halt or change. This allows mobile stations to prepare for the transition, update their configurations proactively, and maintain continuous communication without disconnection or handover failure when the base station is halted or its information is changed.
2Reliability
If the administrator waits for low communication traffic time zone to halt the base station device, then the impact on communication is reduced, but the base station device cannot be halted during high traffic times when maintenance is urgently needed
Solution Approach 1:
The base station transmits information about upcoming changes (cell ID, synchronization information) to mobile stations in advance before actually performing the halt or change. This allows maintenance to be performed at any time (including during high traffic periods) while maintaining communication continuity, as mobile stations are already prepared for the transition.
Solution Approach 2:
The system dynamically adjusts the timing of maintenance operations independent of traffic conditions. By notifying mobile stations in advance of upcoming changes, the base station can perform maintenance at optimal times (including during high traffic periods if urgently needed) without being constrained to low traffic time zones, thus gaining scheduling flexibility while maintaining communication reliability.
3Reliability
If cell ID is changed to avoid conflicts between base station devices, then proper identification is maintained, but synchronization information becomes invalid and requires re-synchronization
Solution Approach 1:
When the base station plans to change its cell ID or other identification information, it transmits notifications about these upcoming changes to mobile stations in advance. This allows mobile stations to update their stored synchronization information and configuration data proactively, ensuring that when the cell ID change actually occurs, the mobile stations already have the correct information and no re-synchronization is needed.

AI summary
A synchronization channel control unit halts generation of a synchronization channel signal. A signal control unit halts generation of signals other than the synchronization channel signal after the synchronization channel control unit halts generation of the synchronization channel signal.
