1Productivity
If only one measurement trigger and one radio access technology are configured in the current logged MDT specifications, then the system maintains simplicity and ease of operation, but it becomes difficult to obtain various measurement results in a short period of time
Solution Approach 1:
The patent segments the measurement configuration by introducing separate configuration containers for intra-RAT measurements (first measurement configuration) and inter-RAT measurements (second measurement configuration). This segmentation allows multiple measurement triggers and target RATs to be configured simultaneously without increasing overall system complexity, as each segment handles a specific measurement type independently.
Solution Approach 2:
The radio terminal is designed with multi-functional measurement capabilities, enabling it to perform both intra-RAT and inter-RAT measurements using a unified measurement framework. The terminal can simultaneously process multiple measurement triggers (A3, A4, A5, B1, B2 events) across different RAT types (E-UTRAN, UTRAN, GERAN), making the measurement system universal and adaptable to various measurement needs without requiring separate dedicated systems for each measurement type.
2Loss of time
If multiple measurement triggers and radio access technologies are configured simultaneously, then various measurement results can be obtained in a short period of time, but the measurement configuration and data management complexity increases
Solution Approach 1:
Measurement data is segmented and stored in separate log structures corresponding to different measurement configurations. The first measurement log stores results from intra-RAT measurements while the second measurement log stores inter-RAT measurement results. This segmentation simplifies data management by organizing multiple measurement streams into distinct, manageable categories, reducing the complexity of processing and analyzing large volumes of simultaneous measurement data.
Solution Approach 2:
The patent introduces an intermediary measurement configuration structure that acts as a mediator between the network's measurement requirements and the terminal's measurement execution. This configuration structure includes specific fields for triggering conditions, measurement objects, and reporting parameters that standardize the interface between network demands and terminal capabilities, simplifying the management of multiple simultaneous measurement tasks.

AI summary
A radio measurement collection method according to the present invention, comprises the steps of: sending IdleMDTConfiguration message for setting a plurality of measurement triggers from E-UTRAN including a radio base station eNB to a radio terminal UE; setting the plurality of measurement triggers in the radio terminal UE by the radio terminal itself according to the IdleMDTConfiguration message from the E-UTRAN; measuring a radio environment for each of the plurality of measurement triggers by the radio terminal UE in an idle mode; and storing, by the radio terminal UE, each measurement result obtained at the measuring step in association with the measurement trigger corresponding to the measurement result.
