Radio Equipment Controller Automatic Standby Line Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, when a fault occurs in the main line between a radio equipment controller (REC) and radio equipment (RE), it disrupts communication, requiring manual onsite processing, increasing maintenance costs and service interruption time, and affecting user experience.
Innovation Solution
The REC determines a standby line for communication, such as a power cable line or a power cable plus CPRI communications line, to maintain connectivity with the RE, allowing automatic switching and reducing the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a main line (CPRI communications line) is used for communication between REC and RE, then communication reliability is improved, but when a fault occurs, manual onsite processing is required which increases maintenance cost and service interruption time
Solution Approach 1:
The patent pre-establishes a standby line (power cable) alongside the main CPRI communication line before faults occur. This standby infrastructure is prepared in advance so that when the main line fails, the system can immediately switch to the pre-configured standby path without requiring manual onsite installation or configuration, thereby reducing maintenance cost and service interruption time while maintaining communication reliability
Solution Approach 2:
The patent introduces a standby power cable as an intermediary communication path. When the main CPRI line fails, this intermediary power cable serves as a backup communication channel, allowing the REC to communicate with the RE through an alternative route. This mediator approach ensures continuous communication while eliminating the need for manual intervention during fault recovery
2Difficulty of detecting and measuring
If manual onsite processing is required when main line fault occurs, then fault location can be identified, but service interruption time increases and user experience deteriorates
Solution Approach 1:
The patent implements automatic fault detection and automatic switching functionality that enables the communication system to service itself without manual intervention. When a fault is detected on the main line, the system automatically switches to the standby power cable communication path, eliminating the need for manual fault detection and repair operations, thereby reducing service interruption time while maintaining fault detection capability
Solution Approach 2:
The system performs preliminary configuration of the standby power cable communication path during normal operation, so that when a fault occurs, the switch to standby mode can happen immediately without requiring manual fault location or repair actions, thus minimizing service interruption time while preserving fault detection abilities

AI summary
Embodiments of the present invention provide an information transmission method, a radio equipment controller, a radio equipment, and a base station. The method includes determining, by an REC, that a main line used for communication with a first radio equipment RE is faulty and determining, by the REC, a standby line used for communication with the first RE. The method also includes communicating with the first RE by using the standby line.
