Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern wireless communication systems face inefficiencies in handover procedures between base stations, leading to unnecessary handovers and degradation of performance due to the lack of centralized control over distributed control messages, especially in multi-hop networks.
Innovation Solution
Implementing a wireless control plane with centralized and distributed control messages, where the control plane is separated from the user plane, allowing for direct communication between network devices and user equipment, and using sub-6 GHz frequencies for control plane connections to reduce the need for handovers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional distributed control messages are used in multi-hop networks, then base stations can independently manage their control plane, but unnecessary handovers are triggered and system performance degrades
Solution Approach 1:
A centralized controller is introduced as an intermediary between base stations and user equipment. The centralized controller receives control messages from base stations, processes them centrally, and determines appropriate handover decisions. This mediator prevents unnecessary handovers by coordinating control plane messages across the network, thereby improving system performance stability while maintaining base station independence through the centralized coordination mechanism.
2Reliability
If handover procedures are implemented frequently to maintain connectivity, then connection reliability improves, but signaling overhead and latency increase
Solution Approach 1:
The centralized controller pre-processes control plane messages and performs predictive analysis to anticipate handover needs before they occur. By analyzing network conditions, signal quality trends, and user equipment movement patterns in advance, the controller prepares handover decisions proactively. This preliminary action reduces the need for frequent reactive handovers, thereby maintaining connection reliability while significantly reducing handover latency and signaling overhead.
3Device complexity
If control plane and user plane are combined, then system complexity is reduced, but resource management efficiency decreases
Solution Approach 1:
The control plane is segmented into two distinct functional components: a centralized control message processing function and a distributed base station execution function. The centralized controller handles control plane message processing, handover decisions, and coordination, while base stations focus on user plane data transmission and local radio resource management. This segmentation allows independent optimization of control and user plane functions, improving resource management efficiency while maintaining manageable system complexity through clear functional separation.
