Neighbor Cell Dual Connectivity Configuration for Throughput Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic neighbor relation (ANR) functions in LTE and NR do not adequately reflect dual connectivity relationships between cells, leading to incorrect configuration of dual connectivity attributes by base stations, which can reduce system throughput.
Innovation Solution
A network management entity determines and configures dual connectivity attributes and capabilities for neighbor cells, ensuring correct configuration by referencing operator policies, thereby preventing incorrect dual connectivity configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If base stations automatically configure dual connectivity attributes without network management intervention, then configuration efficiency is improved, but configuration accuracy deteriorates leading to incorrect dual connectivity settings
Solution Approach 1:
The patent introduces a network management entity as an intermediary between the base station and the dual connectivity configuration. This entity receives neighbor cell relation information from the base station, determines the appropriate dual connectivity attributes based on operator policies, and sends configuration instructions back to the base station. This mediator role ensures that automatic configuration processes maintain high accuracy by incorporating network-level policy decisions.
2Speed
If base stations independently determine dual connectivity capabilities, then system response time is reduced, but throughput performance deteriorates due to incorrect configurations
Solution Approach 1:
The patent implements preliminary action by having the network management entity pre-determine dual connectivity attributes and capabilities before the base station attempts to configure them. The network management entity analyzes operator policies and neighbor cell relationships in advance, preparing configuration instructions that the base station can then apply without real-time decision-making delays, thus maintaining both fast response and optimal throughput performance.
