LTE/5G Network Node Grouping for Conformity-Based Configuration Tuning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cellular network configuration tuning is challenging due to the large number of parameters, complex dependencies, and diverse traffic demands, making it difficult to systematically document and implement optimal settings across different parts of the network, leading to potential misconfigurations that negatively impact quality of service.
Innovation Solution
A method that groups network nodes into reference groups based on configuration and load/mobility attributes, identifies the most prevalent configuration parameter value within each group, and applies this value to all nodes while using performance-based filtering to ensure optimal settings are not overridden by minority configurations that have shown performance improvements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If configuration parameters are tuned individually for each network node to optimize local performance, then local quality of service is improved, but device complexity and difficulty of management increase significantly
Solution Approach 1:
The patent segments network nodes into reference groups based on configuration attributes and load/mobility/radio frequency attributes. By grouping similar nodes together, the system reduces configuration management complexity while maintaining local optimization. Each reference group can be managed as a unified entity rather than individual nodes, directly addressing the contradiction between local performance optimization and management complexity.
Solution Approach 2:
The patent changes the parameter of configuration management from individual node-level tuning to reference group-level tuning. This parameter change allows the system to maintain optimized configuration settings while significantly reducing the complexity of tracking and managing configurations across thousands of individual nodes, resolving the contradiction between reliability and device complexity.
2Device complexity
If configuration settings are standardized across all network nodes, then device complexity is reduced, but adaptability to diverse traffic demands and local conditions deteriorates
Solution Approach 1:
The patent applies local quality by creating reference groups that preserve local characteristics and configuration attributes. Each reference group maintains the specific configuration settings appropriate for its local conditions (downtown, highway, seasonal locations), while the overall system benefits from standardized group-level management. This resolves the contradiction by allowing local adaptability within groups while achieving global standardization at the group level.
Solution Approach 2:
The patent inverts the traditional approach by grouping nodes with similar characteristics together and applying configurations at the group level rather than individual node level. This inversion maintains adaptability to local conditions through group-specific configurations while achieving the simplification benefits of standardized management, resolving the contradiction between standardization and adaptability.
3Manufacturing precision
If manual configuration tuning is performed for each network location, then configuration precision is improved, but productivity and time consumption deteriorate
Solution Approach 1:
The patent uses copying by establishing reference groups where configuration settings from one node can be copied to similar nodes within the same reference group. This maintains configuration precision through proven settings while dramatically improving productivity by avoiding repetitive manual tuning for each individual node. The system copies configurations within reference groups rather than requiring unique manual configuration for every node.
Solution Approach 2:
The patent applies preliminary action by pre-grouping nodes into reference groups based on their attributes before configuration deployment. This preliminary segmentation allows configurations to be prepared and validated at the group level, ensuring precision while accelerating deployment productivity. The grouping action is performed in advance, enabling efficient bulk configuration operations rather than individual node tuning.
4Adaptability or versatility
If configuration parameters are frequently adjusted to respond to seasonal changes and traffic patterns, then adaptability is improved, but stability of configuration settings deteriorates
Solution Approach 1:
The patent applies dynamics by enabling reference groups to be dynamically reconfigured based on changing conditions such as seasonal patterns and traffic demands. Nodes can be moved between reference groups or groups can be redefined as conditions change, allowing the system to adapt to seasonal variations while maintaining stability through the structured reference group framework. This resolves the contradiction between adaptability and stability by providing a dynamic yet organized configuration approach.
