Baseband Processing Panel Direct Path Bypass for Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high implementation costs associated with providing backup baseband processing boards in wireless communication systems, such as 3G and LTE, due to the need for additional fiber optic interfaces, result in increased expenses and potential service disruptions when a baseband processing board fails.
Innovation Solution
Introducing two direct paths for the baseband processing board, one connected in parallel with the baseband processing module and another with the power supply module, allowing the board to switch operation modes and maintain service by reallocating resources and power through a backplane, thereby reducing the need for redundant hardware and interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a backup baseband processing board is additionally provided in the BBU, then the reliability of the baseband processing is improved, but the number of fiber optic interfaces is doubled and the implementation costs are increased
Solution Approach 1:
The patent merges the backup baseband processing board with an existing normal baseband processing board by sharing the optical module and fiber optic interface. When a failure occurs, the backup board takes over the failed board's responsibilities through the shared optical module, eliminating the need for separate dedicated backup interfaces and reducing the total number of fiber optic interfaces required.
Solution Approach 2:
The optical module is designed to serve multiple functions - it acts as the optical interface for the active baseband processing board and simultaneously serves as the backup interface for the standby baseband processing board. This multi-functionality allows the same hardware component to provide both primary and backup communication paths, reducing overall system complexity.

3Device complexity
If traditional baseband processing board configuration is used, then the system structure is simple, but the cell service is interrupted when a baseband processing board fails
Solution Approach 1:
The patent merges the backup baseband processing board with an existing normal baseband processing board by sharing the optical module and fiber optic interface. When a failure occurs, the backup board takes over the failed board's responsibilities through the shared optical module, eliminating the need for separate dedicated backup interfaces and reducing the total number of fiber optic interfaces required.
Solution Approach 2:
The system implements beforehand cushioning by pre-configuring a backup baseband processing board that remains in standby mode with the shared optical module ready to take over. When a failure occurs, the backup board immediately activates and assumes the failed board's responsibilities, preventing service interruption without requiring complex real-time switching mechanisms.

AI summary
Disclosed are a building baseband unit, a baseband processing panel, and a failure processing method for the baseband processing panel. A direct path is introduced respectively for a baseband processing module and a power supply module in a baseband processing panel; when the baseband processing module has failed, the baseband processing module is directly bypassed, and a part of the baseband processing resources of a baseband processing panel in normal operation is allocated to an RRU corresponding to the failed baseband processing panel via a back panel and the direct path; and when both the baseband processing module and the power supply module have failed, both of them are directly bypassed, and a part of the baseband processing resources of a baseband processing panel in normal operation is allocated to the RRU corresponding to the failed baseband processing panel via the back panel and the direct path, and at the same time the power required for working is provided to an optical module via the back panel and another direct path.
