Radio Measurement Subset Selection for Network Energy Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The management of radio resources in radiocommunication networks is complex and energy-intensive due to the need for frequent radio measurements, which generate significant signaling load and energy consumption, especially when optimizing frequency spectrum use across different networks.
Innovation Solution
A method that determines a subset of terminals in a radiocommunication network based on distance and capacity values to selectively perform measurements, reducing the number of terminals involved and thus minimizing energy consumption and signaling load while ensuring relevant data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all terminals perform radio measurements to optimize frequency spectrum use, then measurement data coverage is improved, but energy consumption and signaling load increase significantly
Solution Approach 1:
The patent segments the terminal population into different groups based on their capability values, where only certain segments (terminals with high capability values) are selected to perform measurements. This segmentation allows the system to maintain comprehensive measurement coverage while reducing the number of terminals involved, thereby lowering overall energy consumption.
Solution Approach 2:
The patent applies local quality by assigning different measurement responsibilities to different terminals based on their individual capability values. Terminals with higher capability values are designated to perform measurements, while others are exempted. This localized differentiation optimizes energy consumption while maintaining measurement quality.
2Measurement precision
If all terminals perform radio measurements to optimize frequency spectrum use, then measurement data coverage is improved, but signaling load increases significantly
Solution Approach 1:
The patent segments terminals into groups based on capability values, selecting only specific segments to perform measurements and report results. This reduces the number of signaling messages transmitted to the network entity, thereby lowering signaling load while maintaining adequate measurement coverage.
Solution Approach 2:
By assigning measurement tasks selectively to terminals with appropriate capability values, the patent reduces the number of terminals generating signaling traffic. This localized task assignment decreases overall signaling load in the network.
3Use of energy by moving object
If a subset of terminals is selected to perform measurements based on capability values, then energy consumption is reduced, but measurement coverage may be insufficient
Solution Approach 1:
The patent introduces capability values as a new parameter to characterize terminal measurement ability. By selecting terminals based on this parameter, the system ensures that the subset of measuring terminals provides sufficient coverage while consuming less energy than if all terminals participated.

AI summary
A radio communication network comprises terminals and a network entity. At the level of the network entity, at least one subset of terminals is determined (21) from among the terminals of the network on the basis of the distances between the terminals of the network. Next, a message requesting the implementation of a measurement is sent to at least some of the terminals of said subset. A value representing a level of capacity of a terminal to perform a measurement is associated with each terminal of the subset, and the terminals which perform said measurement are determined on the basis of the values which are respectively associated with them.
