Abstract

The embodiment of the present disclosure provides a method for reporting and configuring MDT measurement, apparatus and electronic device using the same and medium. The method may be performed by a first access network node and includes: obtaining first MDT configuration information; performing MDT measurement according to the first MDT configuration information to obtain a first MDT measurement report; transmitting the first MDT measurement report to a first node, so that the first node combines a second MDT measurement report associated with the first MDT measurement report obtained by the first node with the first MDT measurement report; and/or receiving a third MDT measurement report transmitted by a second access network node, combining the third MDT measurement report and the first MDT measurement report, and transmitting the combined measurement report to a second node. The solution provided in the embodiment of the present disclosure provides an implementation method of reporting MDT measurement when performing MDT measurement at multiple nodes.

First claim

The invention claimed is:

1 . A method for reporting minimization of drive tests (MDT) measurements, which is performed by a first access network node, the method comprising:
obtaining first MDT configuration information, wherein the first MDT configuration information includes a measurement range indicating a group of cells, privacy indication information, and configuration information of where a measurement result is transmitted; performing MDT measurement according to the first MDT configuration information to obtain a first MDT measurement report, wherein the first MDT measurement report comprises bearer type indication information for specifying a bearer to be used on a specific session; and transmitting the first MDT measurement report to a first node, so that the first node combines a second MDT measurement report associated with the first MDT measurement report obtained by the first node with the first MDT measurement report.

2 . The method according to claim 1 , further comprising:
receiving a third MDT measurement report transmitted by a second access network node; combining the third MDT measurement report and the first MDT measurement report; and transmitting the combined measurement report to a second node.

3 . The method according to claim 2 , wherein the first access network node is any one of the followings:
a primary base station, a secondary base station, a central unit (CU) of a base station, a distribute unit (DU) of the base station, a control plane of the CU (CU-CP), and a user plane of the CU (CU-UP), wherein the first node is any one of the followings: a measurement center node, an operation and maintenance node, the primary base station, the secondary base station, the CU, the DU, the CU-CP, and the CU-UP, wherein the second access network node is any one of the followings: the primary base station, the secondary base station, the CU, the DU, the CU-CP, and the CU-UP, and wherein the second node is the measurement center node or the operation and maintenance node.

4 . The method according to claim 3 , wherein each of the first MDT measurement report, the second MDT measurement report, or the third MDT measurement report comprises at least one of the following information:
identifier of MDT measurements; MDT measurement type indication information; type indication information of a node for performing the MDT measurement; measurement level indication information; identification indication information of data radio bearer (DRB); and MDT measurement results.

5 . The method according to claim 1 , wherein the bearer type indication information is set to one of master node (MN) terminated bearer, secondary node (SN) terminated bearer, MN terminated secondary cell group (SCG) bearer, MN terminated split bearer, SN terminated SCG bearer, SN terminated master cell group (MCG) bearer, or SN terminated split bearer.

6 . A method for reporting minimization of drive tests (MDT) measurements, the method comprising:
receiving a first MDT measurement report transmitted by a first access network node; receiving a second MDT measurement report transmitted by a second access network node; and combining the first MDT measurement report and the second MDT measurement report, wherein each of the first MDT measurement report and the second MDT measurement report is obtained based on MDT configuration information, and the MDT configuration information includes a measurement range indicating a group of cells, privacy indication information, and configuration information of where a measurement result is transmitted, and wherein each of the first MDT measurement report and the second MDT measurement report comprises bearer type indication information for specifying a bearer to be used on a specific session.

7 . The method according to claim 6 ,
wherein the method is performed by a first node, the first node is a measurement center node, an operation and maintenance node, and a control plane of a central unit (CU-CP) of a base station, a primary base station or a secondary base station, and wherein, when the first node is the CU-CP, the primary base station, or the secondary base station, after combining the first MDT measurement report and the second MDT measurement report, the method further comprises:
transmitting the combined MDT measurement report to a second node, and the second node comprises the measurement center node or the operation and maintenance node.

8 . The method according to claim 6 , wherein the bearer type indication information is set to one of master node (MN) terminated bearer, secondary node (SN) terminated bearer, MN terminated secondary cell group (SCG) bearer, MN terminated split bearer, SN terminated SCG bearer, SN terminated master cell group (MCG) bearer, or SN terminated split bearer.

9 . A method for configuring minimization of drive tests (MDT) measurements, which is performed by a first access network node, the method comprising:
obtaining information indicating whether a user equipment (UE) allows to perform MDT measurement; receiving MDT configuration information, wherein the MDT configuration information includes a measurement range indicating a group of cells, privacy indication information, and configuration information of where a measurement result is transmitted; selecting the UE for performing the MDT measurement based on the information indicating whether the UE allows to perform MDT measurement and the MDT configuration information; transmitting a cell data tracking message to a second access network node so that the second access network node is triggered to transmit a data tracking request message to a core network node; and performing MDT measurement according to the MDT configuration information to obtain a first MDT measurement report comprising bearer type indication information for specifying a bearer to be used on a specific session.

10 . The method according to claim 9 ,
wherein the first access network node is any one of the followings:
a secondary base station, a central unit (CU) of the secondary base station, and a control plane of the central unit (CU-CP) of the secondary base station,
wherein the second access network node is any one of the followings:
the primary base station, the CU of the primary base station, and the CU-CP of the primary base station, and
wherein the information indicating whether the UE allows to perform MDT measurement comprises at least one of the followings:
information indicating whether to allow the UE to perform management-based MDT measurement; and
a list of public land mobile network (PLMN) identifiers for which the UE performs management-based MDT measurements.

11 . The method according to claim 9 , wherein the bearer type indication information is set to one of master node (MN) terminated bearer, secondary node (SN) terminated bearer, MN terminated secondary cell group (SCG) bearer, MN terminated split bearer, SN terminated SCG bearer, SN terminated master cell group (MCG) bearer, or SN terminated split bearer.

12 . A configuration device for minimization of drive tests (MDT) measurements, which is included in a first access network node, the configuration device comprising:
