Dynamic Border Cell Records for Network Slice Mobility Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network slicing mechanisms fail to recognize that cells within a network can have different policies and protection mechanisms based on whether they are at the coverage boundary or not, leading to inefficiencies in admission, congestion, mobility, and energy efficiency optimizations.
Innovation Solution
A method and apparatus for maintaining and updating a record of border cells of network slices in response to changes in the active cells within a network, ensuring accurate application of policies and control mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network slicing mechanisms treat all cells uniformly without distinguishing border cells, then device complexity is reduced, but network performance and optimization efficiency deteriorate
Solution Approach 1:
The patent segments cells into two distinct categories: border cells and non-border cells. This segmentation allows the network to apply different policies and optimization mechanisms to each type, improving network optimization efficiency while maintaining operational simplicity through automated classification and management.
2Productivity
If border cells are identified and managed separately with specific policies, then network performance and mobility optimization improve, but device complexity and management overhead increase
Solution Approach 1:
The network system automatically identifies border cells based on their geographical and functional characteristics, and self-manages the border cell records without requiring manual intervention. This self-service approach reduces management complexity while enabling sophisticated border cell handling for improved mobility optimization.
3Ease of manufacture
If uniform policies are applied to all cells in a network slice, then ease of policy implementation is improved, but admission control and congestion management efficiency deteriorate
Solution Approach 1:
The patent implements local quality by applying different admission control and congestion management policies to border cells versus non-border cells. Border cells receive specialized policies tailored to their unique characteristics, improving admission control efficiency while the system maintains simplicity through automated policy selection and application.

AI summary
A network node in a cellular communication network maintains a record of border cells of network slices. A change in the cells active in the network is then determined. The record of border cells of network slices is then updated based on said change in the cells active in the network.
