TRX Mutual Aid for Base Station Carrier Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, TRX mutual aid during faults in dominant carriers leads to service congestion and increased load on base station controllers due to limitations in hardware and multi-standard support, causing disruptions in services across different wireless standards.
Innovation Solution
A method where a base station obtains capability information of TRX boards and selects appropriate TRX mutual aid based on this information and cell configuration to perform TRX mutual aid on faulty dominant frequency carriers, including obtaining configuration information from boards operating on different standards to ensure seamless service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station controller reports information of all standards to implement TRX mutual aid, then the dominant B carrier can be recovered, but the load of the base station controller increases radically
Solution Approach 1:
The patent segments the TRX mutual aid functionality by implementing separate processing units: a first processing unit handles same-standard carrier information while a second processing unit handles different-standard carrier information. This segmentation distributes the processing load across specialized modules rather than concentrating all data processing in a single controller, thereby reducing the overall load on the base station controller while maintaining comprehensive carrier recovery capabilities.
2Reliability
If the base station controller implements single-carrier mutual aid, then the dominant B carrier can be recovered, but other carriers on the faulty board cannot provide services causing service congestion
Solution Approach 1:
The patent merges multiple carrier recovery operations into a unified multi-carrier mutual aid process. Instead of recovering only the dominant B carrier through single-carrier mutual aid, the system simultaneously recovers multiple carriers (including dominant B carrier and other carriers) by combining configuration information from multiple sources and executing coordinated recovery operations across several carriers on the faulty board, thereby maintaining both reliability and service capacity.
Solution Approach 2:
The patent implements preliminary action by pre-obtaining and storing configuration information from neighboring cells and other standards before faults occur. This pre-prepared configuration data is kept ready in the base station controller, enabling rapid multi-carrier recovery when faults occur without requiring time-consuming data collection during the recovery process, thus maintaining high service capacity during recovery operations.
3Adaptability or versatility
If a TRX board supports multiple wireless standards, then the base station can provide diverse services, but the base station controller cannot learn configuration information of carriers in other standards affecting normal services
Solution Approach 1:
The patent implements universality by designing a multi-functional information processing architecture where the base station controller contains processing units capable of handling both same-standard and different-standard carrier configuration information. The system universally accepts and processes configuration data from multiple wireless standards (GSM, WCDMA, etc.) through standardized interfaces, enabling the controller to learn and manage carrier configurations across different standards without losing accessibility to critical information.
Solution Approach 2:
The patent introduces an intermediary mechanism through the second processing unit that specifically handles different-standard carrier configuration information. This intermediary processing unit acts as a bridge between multi-standard TRX boards and the base station controller, translating and normalizing configuration information from various standards into a unified format that the controller can process, thereby preventing information loss while maintaining multi-standard versatility.

AI summary
The present invention relates to a method, a base station, and a wireless communication system for TRX mutual aid, where the method comprises: obtaining, by the base station, capability information of a TRX board in the base station, and obtaining from a base station controller information of a cell to which a carrier that is configured on the TRX board belongs; and selecting, by the base station, a corresponding TRX mutual aid way according to the capability information and the information of the cell to perform TRX mutual aid with a faulty BCCH carrier. By implementing TRX mutual aid on the base station, the capability of the board can be easily learned, and the TRX mutual aid is performed based on the capability in comprehensive consideration of another carrier in the cell and standard configuration of the carriers, so that more carriers continue providing services.
