Dynamic Virtual BBU Pooling for Wireless Network Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network optimization processes rely on static relationships between remote radio heads (RRHs) and baseband units (BBUs), which fail to efficiently utilize system resources, leading to suboptimal coverage and capacity without quality degradation.
Innovation Solution
A cloud-based system with a monitor module, detector module, and optimization module that dynamically adjusts the configuration and topology of virtual BBUs to optimize wireless network performance by monitoring performance indicators, detecting operational conditions, and reconfiguring the network to allocate resources effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a static relationship between RRHs and BBUs is implemented, then network configuration is simple and stable, but resource utilization is inefficient and network performance is suboptimal
Solution Approach 1:
The patent implements dynamic BBU pooling where BBUs are no longer statically assigned to RRHs but are dynamically allocated from a centralized pool based on real-time network conditions, traffic demands, and operational requirements. This allows the system to adapt continuously, optimizing resource utilization and network performance while maintaining manageable complexity through automated orchestration.
Solution Approach 2:
The patent creates a universal BBU pool that can serve multiple RRHs simultaneously and be dynamically reassigned based on needs. Instead of dedicated one-to-one mappings, BBUs gain multi-functionality by serving different RRHs at different times, improving overall resource efficiency while the centralized management system handles the complexity of these dynamic assignments.
2Adaptability or versatility
If dynamic reconfiguration of virtual BBUs is implemented, then resource allocation is optimized and network performance improves, but system complexity increases
Solution Approach 1:
The patent implements continuous monitoring of network performance metrics, traffic patterns, and BBU utilization levels, using this feedback to dynamically adjust BBU allocations. The system automatically detects when reconfiguration is needed and executes appropriate scaling operations, providing adaptability while managing complexity through closed-loop control rather than manual intervention.
Solution Approach 2:
The BBU pool manager and network elements autonomously perform self-configuration, self-optimization, and self-healing operations based on monitored conditions. The system automatically scales BBUs up or down, reassigns resources, and adjusts allocations without external intervention, achieving high adaptability while the automation reduces operational complexity.
3Use of energy by moving object
If BBUs are statically assigned to RRHs, then system operation is simple and reliable, but power consumption is high and resource efficiency is low
Solution Approach 1:
The patent implements periodic evaluation of network conditions and BBU utilization, with BBUs being dynamically activated or deactivated based on current demands. Instead of continuous operation of all BBUs, the system periodically assesses needs and adjusts allocations, reducing power consumption during low-demand periods while maintaining reliability through on-demand activation of required resources.
Solution Approach 2:
The patent enables BBUs to be dynamically discarded (deactivated or released from allocation) when not needed and recovered (reactivated or reassigned) when demands arise. The centralized BBU pool manager tracks and manages these transitions, allowing power-efficient operation by keeping only necessary BBUs active while maintaining the capability to quickly recover resources when network conditions change.

AI summary
In some embodiments, an apparatus includes a monitor module configured to monitor a set of performance indicators associated with a first network topology of a wireless network provider system. In the first network topology, a set of virtual baseband units services a set of remote radio heads. The apparatus includes a detector module configured to detect an operational condition of the wireless network provider system based on at least one value associated with the set of performance indicators at a first time. The apparatus further includes an optimization module configured to define, based on the operational condition, a second network topology for the set of virtual baseband units. The optimization module is further configured to send a signal to a virtual baseband unit pool manager to configure the wireless network provider system in the second network topology at a second time after the first time.
