Radio Base Station Neighbor Relation Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, the vast number of neighbour relations between cells results in extensive performance measurement data, overwhelming Operation and Maintenance (O&M) systems with signalling and storage challenges, leading to inefficient data handling and incomplete logical network models.
Innovation Solution
Implementing a method in radio base stations to associate each neighbour relation with a predefined type, where only monitored relations' performance data is collected and sent to the O&M system, reducing unnecessary data transmission and storage, and allowing for more accurate logical network modeling by differentiating between used and unused neighbour relations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all neighbour relations are monitored and data is sent to O&M system, then complete network supervision is achieved, but data transmission volume and storage requirements become excessive
Solution Approach 1:
The patent segments neighbour relations into two distinct categories: monitored neighbour relations and unmonitored neighbour relations. This segmentation allows the system to selectively collect and transmit performance measurement data only for monitored relations, thereby reducing the overall data volume sent to the O&M system while maintaining supervision of critical neighbour relations.
Solution Approach 2:
The patent applies local quality by assigning different monitoring characteristics to different neighbour relations based on their specific properties. Each neighbour relation can be individually configured as monitored or unmonitored, allowing the system to focus resources on relations that require detailed supervision while reducing overhead for relations that do not.
2Device complexity
If the number of neighbour relations per cell is limited, then data management becomes easier, but the logical network model becomes incomplete
Solution Approach 1:
The patent resolves this contradiction by segmenting neighbour relations into monitored and unmonitored categories. This allows the system to maintain a complete logical network model that includes all neighbour relations, while managing data complexity by selectively processing and transmitting information only for monitored relations. The complete model is preserved for network management purposes, while data handling complexity is reduced through selective monitoring.
3Loss of information
If performance measurement data is collected for all neighbour relations, then comprehensive analysis is possible, but O&M system resources are overwhelmed
Solution Approach 1:
The patent extracts only the necessary subset of performance measurement data from the complete set of neighbour relations. By identifying and extracting data only from monitored neighbour relations, the system maintains the ability to perform comprehensive analysis on relevant data while avoiding the resource overhead of processing and analyzing data from all neighbour relations.
Solution Approach 2:
The patent applies partial action by collecting performance measurement data for only a subset of neighbour relations (monitored relations) rather than all relations. This partial data collection is sufficient to achieve the necessary network supervision and analysis goals while significantly reducing the processing burden on the O&M system.

AI summary
A radio base station and a method therein for management of neighbor relations with respect to neighboring radio base stations are provided. The radio base station is connected to an Operation and Maintenance, O&M system requesting performance measurement data relating to the neighbor relations from the radio base station. The radio base station 200, 300, 400 is configured to associate each neighbor relation with a predefined first or a predefined second neighbor relation type, wherein the first neighbor relation type indicates that the neighbor relation is to be monitored and the second neighbor relation type indicates that the neighbor relation is to be unmonitored. The base station is further configured to collect performance measurement data relating to mobility for neighbor relations associated with the first neighbor relation type, and to send the collected performance measurement data only for neighbor relations associated with the first neighbor relation type to the O&M system.
