Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, the complexity of cellular systems and dynamic nature of radio resource management lead to unpredictable consequences when using machine learning for optimization, necessitating a method to safely explore handover conditions without degrading service quality.
Innovation Solution
Implementing an explorative handover mechanism where terminal devices enter a reduced function mode without active data transfer, allowing network nodes to test handover policies by establishing explorative connections with a reduced set of radio functions, collecting measurement data, and adjusting handover execution policies based on the results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If machine learning is used to optimize handover decisions in wireless networks, then network performance and productivity are improved, but the risk of service degradation and reliability issues increases due to unpredictable consequences of complex system interactions
Solution Approach 1:
The patent implements an explorative handover mechanism that performs preliminary testing of handover decisions in a controlled manner before full deployment. Terminal devices in idle or inactive states perform explorative handovers to collect measurement data, allowing the system to evaluate machine learning decisions safely before they impact active service quality.
Solution Approach 2:
The patent introduces an intermediary explorative connection layer between the machine learning optimization and the actual service delivery. This intermediary mechanism uses terminal devices in reduced-function modes to test handover policies, acting as a buffer that isolates potential negative effects from active service while still enabling performance improvement through data collection.
2Measurement precision
If explorative handover testing is performed with full radio connection functions, then measurement data quality is improved, but service degradation and network resource waste increase
Solution Approach 1:
The patent changes the operational parameters of terminal devices during explorative handovers by putting them in idle or inactive states with reduced radio connection functions. This parameter adjustment allows the system to collect necessary measurement data while consuming minimal network resources and energy, as the terminal devices perform only essential handover testing functions.
Solution Approach 2:
The patent applies partial action by enabling only the necessary radio connection functions required for explorative handover testing, rather than activating the full set of functions. Terminal devices perform explorative handovers with a reduced function set, collecting sufficient measurement data without the overhead of complete service functionality.
3Quantity of substance
If explorative handover is implemented for all terminal devices, then statistics for machine learning algorithms are increased, but device complexity and operational difficulty increase
Solution Approach 1:
The patent applies local quality by implementing explorative handovers selectively for specific terminal devices in specific states (idle or inactive), rather than universally for all devices. This localized approach concentrates the complexity burden on a subset of devices that are naturally better suited for explorative operations, while maintaining normal operations for active service devices.
Solution Approach 2:
The patent introduces dynamics by allowing terminal devices to transition between normal operation mode and explorative handover mode based on their current state. Devices dynamically switch to explorative mode when idle or inactive, enabling the system to adapt complexity requirements to actual device conditions rather than imposing static complexity on all devices.

AI summary
This document discloses a solution for performing exploration of radio resource management actions. According to an aspect, a method in a terminal device includes: receiving configuration information from a network node of a radio access network; entering, in response to the configuration information and in a state of not having a need to transfer data, an exploration mode where a reduced set of radio connection functions are enabled compared with a default operating mode; triggering, in the exploration mode, an explorative handover from a source cell managed by the network node to a target cell; establishing a radio connection with a target network node as a result of the explorative handover to the target cell managed by the target network node; acquiring measurement data of the radio connection and transmitting the measurement data to the target network node.
