5G Base Station Load Assessment for Fixed Wireless Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G non-standalone architecture, 5G base stations become overloaded due to long-term connections with fixed wireless access devices, leading to degraded Internet service speed and resource consumption from repeated reboots and reconnections.
Innovation Solution
A management system determines the load of 5G base stations before connecting them to fixed wireless access devices, providing load information to the 4G base station to rank and select 5G base stations based on their loads, optimizing connections to prevent overloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If 5G base stations establish connections with fixed wireless access devices based on signal strength and frequency band priority, then connection establishment is simplified and mobility is maintained, but base stations become overloaded leading to degraded service quality
Solution Approach 1:
The system performs preliminary load assessment of 5G base stations before establishing connections with fixed wireless access devices. The load information is obtained in advance and used to rank base stations, ensuring that connections are established only with underloaded base stations, thereby preventing overload conditions while maintaining simplified connection procedures
Solution Approach 2:
The system implements a feedback mechanism where load information from 5G base stations is continuously monitored and used to dynamically adjust connection decisions. The ranking of base stations based on load information provides feedback that guides the selection process, ensuring service quality is maintained while preserving ease of connection establishment
2Speed
If 5G base stations accept connections without load assessment, then connection speed is fast and network resources are utilized maximally, but repeated reboots and reconnections consume excessive computing resources
Solution Approach 1:
Load assessment is performed in advance before connection establishment, allowing the system to identify suitable base stations upfront. This preliminary action prevents failed connections and subsequent reboots, maintaining fast connection speeds while avoiding the waste of computing resources on unsuccessful connection attempts
Solution Approach 2:
The system introduces an intermediary load assessment mechanism that mediates between the desire for fast connections and the need to conserve resources. By using load information as an intermediary criterion, the system可以快速 establish connections with suitable base stations while avoiding connections that would lead to overloads and resource-wasting reconnections
3Reliability
If 5G base stations are selected based on signal strength alone, then connection reliability is high, but base station load is not considered leading to overloading and service degradation
Solution Approach 1:
The system changes the selection parameters from considering only signal strength to considering both signal strength and load information. By introducing load as an additional parameter and using it to rank base stations, the system maintains connection reliability while preventing base station overloading, thus preserving productivity and service capacity
