Base Station UE Access Control for High-Speed Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed moving device dedicated networks experience congestion due to user equipment (UE) accessing them even when not in high-speed motion, affecting communication quality, as UEs prefer networks with higher signal intensity, leading to overcrowding and reduced quality for high-speed moving UEs.
Innovation Solution
A method and device for determining the motion state of UE in high-speed moving device dedicated networks, allowing control of UE access to public networks based on motion state, by analyzing historical access data and preset values to direct low-speed motion UEs to access public networks, thereby reducing congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If UEs access the high-speed moving device dedicated network based on signal intensity, then the network coverage and accessibility are improved, but the network congestion and communication quality for high-speed moving UEs deteriorate
Solution Approach 1:
The patent changes the access control parameter from static signal intensity threshold to dynamic motion state-based control. The base station determines UE motion state (high-speed or low-speed) and applies different access policies: high-speed UEs are allowed to access the dedicated network while low-speed UEs are redirected to public networks, thereby resolving the contradiction between accessibility and communication quality
Solution Approach 2:
The base station performs preliminary motion state determination and network selection before UE access. By evaluating the UE's motion state in advance and proactively guiding low-speed UEs to public networks, the system prevents congestion before it occurs, maintaining both accessibility for legitimate users and communication quality for high-speed users
2Reliability
If the high-speed moving device dedicated network is deployed to guarantee communication quality for high-speed UEs, then the communication quality for high-speed moving UEs is improved, but the network congestion caused by low-speed UEs accessing the same network worsens
Solution Approach 1:
The patent segments the network access rights based on UE motion state. The high-speed moving device dedicated network is segmented to serve only high-speed UEs, while low-speed UEs are directed to public networks. This segmentation isolates the two user groups, ensuring that low-speed UEs do not contribute to congestion in the dedicated network while maintaining communication quality for high-speed users
Solution Approach 2:
The base station acts as an intermediary that mediates between UEs and networks based on motion state. It receives access requests from UEs, determines their motion state, and directs them to appropriate networks (dedicated or public). This intermediary function prevents low-speed UEs from accessing the dedicated network, thereby avoiding congestion while preserving communication quality for high-speed users
