Baseband Processing Board Load Balancing via Protocol Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The processing capability of baseband processing boards (BBPs) in mobile communications systems is often insufficient, particularly during high-traffic events, leading to reduced user experience and inefficient resource utilization.
Innovation Solution
Implementing a BBP assistance mechanism where a redundant BBP with lower load assists a BBP with higher load by sharing data transmission protocol processing, balancing inter-board loads and enhancing overall processing capability through intra-board and inter-board resource sharing.

Engineering Contradiction Analysis
1Productivity
If a single BBP handles all processing tasks, then device complexity is reduced, but processing capability becomes insufficient during high-traffic events
Solution Approach 1:
The patent segments the baseband processing functions by introducing a master BBP and slave BBPs. The master BBP handles control plane protocol processing and scheduling, while slave BBPs handle data transmission protocol processing. This segmentation allows the system to scale processing capability by adding slave BBPs without proportionally increasing control complexity, as the master BBP coordinates the distributed slave BBPs.
Solution Approach 2:
The slave BBPs are designed with multi-functionality, capable of handling various data transmission protocol processing tasks across different carriers and terminals. They can dynamically assume different processing roles based on load conditions, enhancing overall system productivity without requiring dedicated specialized hardware for each function.
2Reliability
If traffic control is implemented to manage BBP load, then processing capability is preserved, but user experience deteriorates
Solution Approach 1:
The patent implements dynamic load balancing where slave BBPs can be dynamically activated or deactivated based on real-time traffic conditions. When traffic load exceeds the master BBP's capacity, slave BBPs are activated to share the data transmission protocol processing load. This dynamic adaptation ensures processing capability is maintained during high-traffic events without implementing restrictive traffic control that would degrade user experience.
3Productivity
If all protocol processing is handled by one BBP, then device complexity is reduced, but resource utilization becomes inefficient during variable load conditions
Solution Approach 1:
The system implements feedback mechanisms where the master BBP monitors the load status of slave BBPs and dynamically adjusts task allocation. Based on feedback regarding processing queue depths and resource availability, the master BBP redistributes data transmission protocol processing tasks to optimize resource utilization. This feedback-driven dynamic allocation improves productivity during variable load conditions while maintaining manageable device complexity through centralized coordination.

AI summary
Embodiments of the present invention provide a method for enhancing a processing capability of a base station, a baseband device, a base station, and a system. The method includes: receiving, by a base station, data of a terminal; performing control plane protocol processing on the terminal by using a first BBP, and performing all or part of data transmission protocol processing on the data of the terminal by using a second BBP; and sending processed data of the terminal. In this way, another BBP shares all or part of data transmission protocol processing for a terminal that accesses a BBP, to enhance a processing capability of the base station on the whole, thereby implementing inter-board load balancing.
