Base Station Access Control via Denied List
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In redundant wireless coverage environments, network operators face challenges in efficiently managing user device attachments to base stations, leading to unnecessary expenditures and potential coverage gaps.
Innovation Solution
The method involves selectively rejecting access requests for user devices based on network parameters, adding less utilized base stations to a denied list, and allowing devices to attach only to base stations not on the denied list, thereby driving attachment towards a preferred set of base stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional cell selection is used in redundant coverage environments, then user devices can attach to any available base station, but network operators cannot control attachment distribution and incur unnecessary expenditures
Solution Approach 1:
The system changes the network parameter by introducing a denied list that dynamically controls base station accessibility. This parameter change enables the network to steer attachments away from redundant base stations toward preferred ones, resolving the contradiction between attachment control capability and network expenditure by making the network intelligent in its resource allocation
Solution Approach 2:
The denied list acts as an intermediary mechanism between the network operator's consolidation goals and the user device's attachment process. By mediating through this list, the network can indirectly control device attachments without directly managing each connection, thus reducing expenditures while maintaining control capability
2Productivity
If base stations are added to a denied list to drive attachments, then attachment distribution is optimized, but device attachment process becomes more complex
Solution Approach 1:
The system employs self-service by allowing user devices to automatically handle the complexity of denied list checking and base station selection. The device's conventional cell selection mechanism naturally adapts to the denied list constraints without requiring additional complexity in the network infrastructure, thus achieving attachment optimization while minimizing added complexity
Solution Approach 2:
The solution applies partial action by implementing denied list checks only at specific points in the attachment process rather than throughout the entire system. This selective application optimizes attachment distribution without unnecessarily complicating the overall attachment workflow, balancing productivity improvement with complexity management
3Reliability
If redundant base stations are maintained for coverage, then coverage reliability is improved, but network costs increase due to underutilized stations
Solution Approach 1:
The system introduces dynamics by making base station status flexible through the denied list mechanism. Base stations can dynamically transition between active and denied states based on utilization metrics and network consolidation goals. This dynamic approach allows the network to maintain coverage reliability by keeping necessary stations active while reducing costs by temporarily or permanently denying access to redundant underutilized stations
Solution Approach 2:
The solution implements periodic action through regular evaluation of base station utilization metrics and periodic updates to the denied list. This periodic reassessment allows the network to maintain coverage reliability by continuously monitoring which stations remain necessary while identifying underutilized stations for denial, thus optimizing the balance between reliability and resource utilization over time

AI summary
Embodiments of the present disclosure are directed to systems and methods for managing attachment requests for UEs in a wireless network environment comprising a first set of base stations and a second set of base stations when the first and second set of base stations have at least one unique network characteristic. By rejecting attachment requests to UEs attempting to access one or more base stations of the second set of base stations, the conventional cell selection and attachment process will drive UEs to attach to the first set of base stations.
