24、SI TS 137 320 V14.0.0 (2017-04)53GPP TS 37.320 version 14.0.0 Release 141 Scope The present document provides an overview and overall description of the minimization of drive tests functionality. The document describes functions and procedures to support collection of UE-specific measurements for MD
25、T using Control Plane architecture, for both UTRAN and E-UTRAN. Details of the signalling procedures for single-RAT operation are specified in the appropriate radio interface protocol specification. Network operation and overall control of MDT is described in OAM specifications. NOTE: The focus is o
26、n conventional macro cellular network deployments. In the current release no specific support is provided for H(e)NB deployments. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either spec

Immediate MDT: MDT functionality involving measurements performed by the UE in CONNECTED state and reporting of the measurements to eNB/RNC available at the tim
34、e of reporting condition as well as measurements by the network for MDT purposes. Logged MDT: MDT functionality involving measurement logging by UE in IDLE mode, CELL_PCH, URA_PCH states and CELL_FACH state when second DRX cycle is used (when UE is in UTRA) for reporting to eNB/RNC at a later point
35、in time, and logging of MBSFN measurements by E-UTRA UE in IDLE and CONNECTED modes. Management Based MDT PLMN List: MDT PLMN List applicable to management based MDT. MDT measurements: Measurements determined for MDT. MDT PLMN List: A list of PLMNs where MDT is allowed for a user. It is a subset of

46、tion of drive tests are the following: 1. MDT mode There are two modes for the MDT measurements: Logged MDT and Immediate MDT. There are also cases of measurement collection not specified as either immediate or logged MDT, such as Accessibility measurements. 2. UE measurement configuration It is pos
47、sible to configure MDT measurements for the UE logging purpose independently from the network configurations for normal RRM purposes. However, in most cases, the availability of measurement results is conditionally dependent on the UE RRM configuration. 3. UE measurement collection and reporting UE
48、MDT measurement logs consist of multiple events and measurements taken over time. The time interval for measurement collection and reporting is decoupled in order to limit the impact on the UE battery consumption and network signalling load. 4. Geographical scope of measurement logging It is possibl
49、e to configure the geographical area where the defined set of measurements shall be collected. 5. Location information The measurements shall be linked to available location information and/or other information or measurements that can be used to derive location information. 6. Time information The measurements in measurement logs shall be linked to a time stamp. 7. UE capability information The network may use UE capabilities to select terminals for MDT measurements. 8. Dependency on SON The solutions for MDT are able to work independentl
