Solution Overview
Problem
Conventional methods for minimizing drive tests in mobile communication networks face challenges such as high data collection, continuous measurement by user equipment, excessive network resource usage, and energy consumption, leading to complex data analysis and potential degradation of quality of service.
Innovation Solution
Implementing filtering mechanisms within the mobile communication network to reduce data traffic and resource usage by selectively activating and deactivating user equipment for measurements based on real-time conditions, internal properties, and dynamic network performance, thereby optimizing the selection and activation of measuring entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous measurement by user equipment is performed, then measurement precision is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic measurement activation where user equipment alternates between measuring and non-measuring states. The network entity controls this by sending activation indications to specific user equipment at specific times, allowing measurements to be performed periodically rather than continuously, thus reducing energy consumption while maintaining measurement precision when needed.
2Measurement precision
If all user equipment performs measurements continuously, then measurement precision is improved, but network resource usage increases
Solution Approach 1:
The patent extracts the measurement function from all user equipment and concentrates it on specifically selected measuring user equipment. The network entity identifies and designates particular user equipment as measuring entities based on their capabilities and current network conditions, allowing only these selected devices to perform measurements and report data, thereby reducing overall network resource usage while maintaining measurement precision.
3Measurement precision
If data collection is increased, then measurement precision is improved, but data analysis complexity increases
Solution Approach 1:
The patent extracts and filters measurement data at the source by having the network entity selectively request and collect data only from measuring user equipment that are specifically designated for certain measurement tasks. This selective data collection approach reduces the overall volume of data requiring analysis while maintaining measurement precision through targeted measurements from capable devices.

AI summary
A method for measuring network operation related parameters in a mobile communication network with a core network and a radio-access network, preferably in form of a LTE- or UMTS-network, includes the steps of a) configuring an entity in the mobile communication network for measuring including network operation related parameters to be measured, b) selecting a measuring entity, c) measuring the network operation related parameters by the measuring entity, and d) analyzing the measured parameters wherein a filtering is performed prior to step d), wherein the filtering is performed on an entity in the radio access network of the mobile communication network and wherein the filtering reduces the amount of data of the measured network operation related parameters for step d).
