Dual Connectivity Base Station Management for Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication networks face challenges in data transmission due to restricted resource usage and poor signal quality, leading to uneven load distribution among Low Power Nodes (LPNs) and frequent inter-cell handovers, resulting in decreased user experience and network congestion.
Innovation Solution
Implementing dual connectivity by allowing user equipment to maintain simultaneous connections with multiple network nodes, enabling flexible data routing and shunting between these nodes to ensure continuous service and reduce control plane signaling impact, while maintaining backward compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dual connectivity is implemented to allow user equipment to maintain simultaneous connections with multiple network nodes, then user data service performance and network load balancing are improved, but device complexity and system resource management become more complex
Solution Approach 1:
The patent segments the connection management by introducing a primary network node and secondary network nodes. The primary node handles control plane functions while secondary nodes handle user plane data transmission. This segmentation allows complex dual connectivity to be managed through divided responsibilities, improving user data service performance without overwhelming system resource management.
Solution Approach 2:
The patent introduces a mobility management entity as an intermediary that coordinates between multiple network nodes and user equipment. This intermediary manages the complexity of simultaneous connections by handling bearer management and resource allocation, thereby improving productivity while controlling system complexity through centralized coordination.
2Reliability
If frequent inter-cell handovers are performed to maintain connection quality, then signal quality is improved, but service interruption and signaling congestion increase
Solution Approach 1:
The patent establishes dual connectivity in advance before handover is needed. User equipment maintains simultaneous connections with both primary and secondary network nodes beforehand, so when handover is required, data can be immediately switched to the secondary node without service interruption. This preliminary establishment of multiple connections eliminates service interruption time while maintaining connection quality.
Solution Approach 2:
The patent ensures continuous data transmission by maintaining active connections with multiple network nodes simultaneously. When one connection degrades, the other connection continues to carry data traffic without interruption. This continuity of useful action maintains reliability while eliminating service interruption that would occur with traditional sequential handovers.
3Quantity of substance
If more Low Power Nodes are deployed to increase network capacity, then network coverage and capacity are improved, but load balancing flexibility and handover frequency increase
Solution Approach 1:
The patent makes network nodes multi-functional by enabling them to serve as both primary and secondary nodes depending on conditions. Any network node can fulfill control plane functions or user plane functions based on system needs. This universality provides load balancing flexibility across the expanded network of Low Power Nodes, allowing efficient resource utilization while maintaining high network capacity.
Solution Approach 2:
The patent introduces dynamic role assignment where network nodes can switch between primary and secondary roles based on real-time conditions such as signal quality, load status, and user equipment location. This dynamic adaptability allows the system to flexibly balance load across multiple Low Power Nodes while maintaining optimal connection quality, solving the flexibility problem introduced by network expansion.
