UE Measurement Log Filtering for Lower Wireless Reporting Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transmission of large measurement log files from user equipment (UE) to network devices increases network traffic and delays other messages or signals, reducing system performance by adding latency in wireless communication systems.
Innovation Solution
Implementing selective measurement reporting techniques where a base station transmits measurement filters to the UE, allowing the UE to apply these filters to measurement log files, identifying and excluding certain results, thereby reducing the amount of data communicated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the UE transmits all measurement results from measurement log files to the network device, then the network device obtains complete measurement data for analysis, but the network traffic increases and other messages or signals are delayed
Solution Approach 1:
The patent extracts only the necessary measurement results from the measurement log files based on measurement filters received from the network device. The UE applies filters to identify and transmit only relevant measurement data (first measurement results) while excluding unnecessary data (second measurement results), thereby reducing transmission volume and delay.
Solution Approach 2:
The measurement log files are segmented into multiple measurement results, and further segmented into first measurement results (to be transmitted) and second measurement results (to be excluded) based on the measurement filters. This segmentation allows selective transmission of only necessary data portions.
2Loss of information
If the UE transmits all measurement results from measurement log files to the network device, then the network device has comprehensive measurement data, but the storage and processing resources required at the network device increase
Solution Approach 1:
The network device extracts only the necessary measurement results from the measurement log files by sending measurement filters to the UE. These filters enable the UE to identify and transmit only relevant measurement data, reducing the overall data volume that needs to be stored and processed at the network device.
3Loss of time
If the UE applies measurement filters to select only certain measurement results, then the network traffic is reduced and transmission delay is minimized, but the device complexity at the UE increases
Solution Approach 1:
The measurement filters are prepared and sent to the UE in advance by the network device before the actual measurement data transmission. This preliminary action allows the UE to have the filtering criteria ready, reducing the complexity of real-time filtering operations during data transmission.

AI summary
A method of wireless communication includes determining, based on a plurality of network measurements performed by a user equipment (UE), one or more measurement log files associated with the plurality of network measurements. The method further includes receiving, by the UE from a network device, a request associated with the one or more measurement log files. The request indicates at least one measurement filter. The method further includes transmitting, by the UE to the network device, a response to the request. The response includes first measurement results of the one or more measurement log files selected based on the at least one measurement filter and excludes second measurement results of the one or more measurement log files based on the at least one measurement filter.
