Technique for aggregating minimization of drive test, MDT, measurements in a component of an operating and maintenance, OAM, system

摘要

A technique for aggregating Minimization of Drive Test, MDT, measurements is disclosed. In a first method aspect, the method is performed by a component of an Operation And Maintenance, OAM, system and comprises the steps of receiving an activation request configuring MDT measurements for a plurality of User Equipments, UEs, and requesting a Performance Measurement, PM, activating the MDT measurements for the UEs, receiving the MDT measurements from the UEs, and aggregating the MDT measurements to obtain the requested PM measurement. In a second method aspect, the method is performed in another component of the OAM system and comprises the steps of generating the activation request configuring MDT measurements for the plurality of UEs, and requesting the PM, and transmitting the activation request towards the component of the OAM system.

1. A method of operating a component of an Operation And Maintenance (OAM) system, the method comprising:
receiving an activation request configuring Minimization of Drive Test (MDT) measurements for a plurality of User Equipments (UEs), the activation request comprising a job type parameter signaling a Performance Measurement (PM) request, and requesting a PM measurement report; activating the MDT measurements for the UEs; receiving the MDT measurements from the UEs; aggregating the received MDT measurements into PM measurements to obtain the requested PM measurement report to be reported to an OAM Network Manager (NM); and reporting the PM measurement report, wherein the PM measurement and the PM measurement report comply with at least one of 3rd Generation Partnership Project (3GPP) Technical Specification (TS) 32.425 for E-UTRAN PM measurements, 3GPP TS 32.405 for UTRAN measurements and 3GPP TS 32.401 for requirements for PM measurements.
