Solution Overview
Problem
Modern wireless communication networks face challenges in efficiently managing and optimizing radio resources due to the complexity of dynamically changing environments, especially with the rapid deployment of smaller network cells, leading to interference issues and the need for frequent manual intervention.
Innovation Solution
The implementation of extended Management Information Bases (eMIBs) that allow radio access nodes to receive default settings, dynamically adjust parameters through self-optimization processes, and revert to temporary settings during failures, enabling automated management and reduced human intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional centralized radio resource management is used, then network control is maintained, but manual intervention is required frequently and device complexity increases
Solution Approach 1:
The patent implements self-service by enabling radio access nodes to automatically manage their own radio resources through locally stored MIBs that contain optimization parameters. The nodes autonomously adjust transmission parameters, select channels, and optimize handovers without requiring continuous manual intervention or complex centralized control, thereby achieving automation while reducing overall system complexity.
Solution Approach 2:
The patent segments the centralized management function by distributing MIBs to individual radio access nodes. Each node maintains its own copy of the MIB with optimization parameters specific to its location and conditions, allowing independent decision-making. This segmentation eliminates the need for complex centralized control while maintaining network-wide coordination through shared parameter structures.
2Productivity
If manual intervention is used for network optimization, then control precision is maintained, but time consumption and operational complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring optimization parameters within the MIB structure before deployment. These parameters include default values, adjustment ranges, and optimization algorithms that are ready to be executed automatically. This eliminates the need for manual intervention during routine optimization tasks, significantly reducing time consumption while maintaining precise control through pre-defined parameter structures.
Solution Approach 2:
The patent implements feedback mechanisms where radio access nodes continuously monitor network conditions and automatically adjust parameters based on measured performance. The nodes use feedback from signal quality, traffic patterns, and interference levels to dynamically optimize their operation, replacing time-consuming manual optimization processes with automated closed-loop control that maintains high productivity.
3Adaptability or versatility
If network cells are deployed rapidly, then network capacity increases, but interference issues and management complexity increase
Solution Approach 1:
The patent applies local quality by enabling each radio access node to store and execute location-specific optimization parameters within its local MIB. Each node adjusts its transmission characteristics based on local interference conditions, neighboring cell configurations, and geographic location. This allows rapid deployment of new cells while automatically managing interference through localized parameter optimization, maintaining network capacity growth without proportionally increasing harmful interference.
Data Source
AI summary
A networked computing system, including multiple radio access nodes (RANs), multiple radio communications controllers (RCCs), and a data communications network facilitating communications amongst the RANs and the RCCs of the system. A regional RAN receives a default eMIB associated with a first type of RAN (e.g., a macrocell, microcell, picocells, or femtocell RAN types) from a RCC, in response to a registration event of a RAN initialization process. The regional RAN maintains a dynamic eMIB comprising network operating parameters determined by various self-optimization processes. The network operating parameters of the dynamic eMIB are selected to fall within a range designated by the default eMIB. During a network failure condition, the regional RAN is configured to use a temporary eMIB comprising failure level operating parameters in order to mitigate network deficiencies caused by the network failure condition.
