SON Report Storage Across Public and Non-Public Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-organizing network (SON) report loss in communication devices, particularly when transitioning between public and non-public networks, leads to sub-optimal network performance due to overwritten or deleted reports, which could have prevented radio link failures.
Innovation Solution
Communication devices store SON reports in different data structures or with associated network identifiers, allowing simultaneous storage and preservation of multiple reports across various network types, ensuring they are not overwritten during mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a communication device stores only the latest SON report in a single data structure, then storage space is optimized, but SON report loss occurs when transitioning between network types
Solution Approach 1:
The patent segments the storage system into separate data structures for different network types (public network and non-public network). Instead of using a single unified storage structure, the device now maintains distinct storage areas (e.g., first data structure for public network reports, second data structure for non-public network reports), preventing report overwriting and ensuring comprehensive SON report preservation across network transitions.
2Reliability
If a communication device stores multiple SON reports simultaneously, then network optimization capability is improved, but storage memory consumption increases
Solution Approach 1:
The patent divides the storage memory into segmented regions allocated to different network types. Each segment (first data structure for public network, second data structure for non-public network) stores reports independently, allowing the device to maintain multiple reports simultaneously without excessive memory consumption in any single region, thus balancing reliability and resource usage.
3Loss of information
If a communication device overwrites old SON reports with new reports, then storage efficiency is maintained, but historical network event data is lost
Solution Approach 1:
The patent implements segmented storage where historical event data is preserved in network-type-specific data structures. The first data structure retains public network reports while the second data structure retains non-public network reports, eliminating the overwriting problem and ensuring complete historical data preservation without compromising processing efficiency.
Solution Approach 2:
The patent establishes preliminary storage allocation for different network types before reports are generated. By pre-defining separate data structures for public and non-public network reports, the system proactively prevents data loss before it occurs, rather than attempting to recover or manage reports after overwriting has happened.
Data Source
AI summary
A method performed by a communication device (12) is disclosed. The communication device (12) stores, at the communication device (12), a self-organizing network, SON, report (16) associated with a non-public network, NPN, including storing the SON report (16) in association with an NPN identifier of the NPN with which the SON report (16) is associated. The communication device (12) also transmits a message to the serving network indicating that the SON report (16) is available at the communication device (12), if a serving network of the communication device (12) is an NPN identified by an NPN identifier which matches the NPN identifier associated with the SON report (16).
