Multi-Technology Threshold Node Selection for 5G Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunication networks face challenges in maintaining continuous coverage for user devices as they move across different target nodes, leading to frequent hand-off events and disruptions.
Innovation Solution
Assigning user devices to target nodes based on a multi-technology threshold, which increases the geographic area of operation without the need for hand-off events by determining signal strengths within a delta range threshold and selecting the node with the lowest multi-technology threshold.

Engineering Contradiction Analysis
1Reliability
If user devices are assigned to target nodes based on signal strength, then the user device can maintain connection quality, but the geographic coverage area is limited and frequent hand-off events occur
Solution Approach 1:
The patent changes the assignment parameter from signal strength to a multi-technology threshold that incorporates signal strength along with other factors such as network load, device capabilities, and technology type. This parameter transformation allows the system to maintain connection quality while expanding the effective coverage area by making assignment decisions based on a more comprehensive metric that doesn't require as frequent re-evaluation.
2Area of stationary object
If user devices are reassigned to different target nodes at network edges, then continuous coverage is maintained, but hand-off events cause disruptions and service interruptions
Solution Approach 1:
The system performs preliminary evaluation of multiple target nodes using the multi-technology threshold before the user device actually reaches the edge of the current node's coverage area. By pre-determining the optimal target node based on the comprehensive threshold metric, the system prepares for the transition in advance, allowing for smoother hand-offs with minimal disruption to service continuity.
3Device complexity
If traditional signal strength-based assignment is used, then simple assignment logic is maintained, but frequent hand-off events increase network complexity and reduce efficiency
Solution Approach 1:
The multi-technology threshold serves multiple functions simultaneously: it evaluates signal strength, assesses network conditions, determines device compatibility, and identifies optimal target nodes. This universal metric consolidates what would otherwise require multiple separate evaluation processes, maintaining relatively simple assignment logic while significantly improving network efficiency by reducing the frequency of hand-off events.

AI summary
Systems and methods are provided for extending coverage of a telecommunication network includes a user device and a cell site. The cell site includes a node management system communicatively coupled to the user device. The node management system is structured to receive one or more signal strengths associated with one or more target nodes, determine the one or more signal strengths are within a delta range threshold, determine one or more multi-technology thresholds associated with the one or more target nodes, determine a lowest multi-technology threshold based on the one or more multi-technology thresholds, and assign the user device to the one or more target nodes associated with the lowest multi-technology threshold determined.
