Dual Connectivity Handover Weighting for Neighbor Relations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In networks supporting dual connectivity, such as E-UTRAN New Radio (NR) Dual Connectivity (EN-DC), existing automatic neighbor relation (ANR) systems face challenges in optimizing handover decisions due to insufficient information about the quality of dual connectivity coverage, leading to futile handovers and resource inefficiencies.
Innovation Solution
The system determines a weighting factor for pairings of network nodes based on user equipment data and metrics like network resource demand, node capabilities, and available resources, enabling intelligent handover target selection and optimized neighbor list management to ensure suitable dual connectivity coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing ANR systems are used in dual connectivity networks, then basic handover functionality is maintained, but handover decisions are suboptimal due to insufficient information about dual connectivity coverage quality
Solution Approach 1:
The system performs preliminary actions by determining weighting factors for network node pairings in advance, based on node capabilities and available resources. This preparation enables more informed handover decisions later, addressing the information deficiency that causes suboptimal handovers in existing ANR systems.
Solution Approach 2:
The system implements feedback mechanisms by monitoring handover outcomes and dual connectivity establishment results. This feedback is used to continuously refine weighting factors for network node pairings, improving handover decision quality over time while compensating for initial information gaps about dual connectivity coverage.
2Productivity
If traditional ANR neighbor list management is used, then neighbor relations are maintained, but computing resources are wasted on futile handovers and suboptimal target selection
Solution Approach 1:
The system changes key parameters by introducing weighting factors that quantify the suitability of network node pairings for dual connectivity. These weighting factors are determined based on node capabilities, available resources, and user equipment data, enabling more efficient handover target selection that reduces futile handovers and conserves computing and network resources.
Solution Approach 2:
The system applies dynamics by making the neighbor list management adaptive and dynamic. Weighting factors are continuously updated based on changing network conditions, node capabilities, and resource availability. This dynamic approach allows the system to optimize handover decisions in real-time, improving productivity while reducing resource waste compared to static traditional ANR systems.
3Reliability
If handover decisions are made without weighting factors, then handover process is simple, but target selection is suboptimal leading to increased handover count
Solution Approach 1:
The system performs preliminary calculations to determine weighting factors for network node pairings based on node capabilities and resource availability. This advance preparation adds complexity to the decision mechanism but enables more reliable dual connectivity coverage by ensuring handover targets are selected based on comprehensive evaluation rather than simple criteria.
