In an example embodiment, the SN network element triggering a management-based MDT measurement is used as an example, where the measurement objects measured at this MDT are M5 and M7.
In operation 0, a main base station and a secondary base station establish a MR-DC for a terminal. In the embodiments of the present application, the main base station sends an S-NODE ADDTITION REQUSET message through an Xn interface or an X2 interface. The S-NODE ADDTITION REQUSET message carries information about SN terminated MCG bearer, and the SN sends an S-NODE-RECONFIGURATION COMPLETE message to an MN after the SN has been configured. The MN and the SN may establish one SN terminated MCG bearer for a terminal.
In operation 1, a network management of the SN sends a management-based MDT measurement activation request to a secondary base station. For example, the network management of the SN configures different management-based MDT measurement activation request configurations for the SN and the MN, respectively, due to that radio access technologies used by the SN and the MN may be different. Referring to
An interface between a base station and the network management is used for the configuration, and the measurement configuration information configured by the SN may include following parameters:
In operation 2, the secondary base station sends activation information for measurement configuration to the main base station. In the embodiments of the present application, after a management-based MDT measurement request is received, the secondary base station selects a terminal satisfying the condition to perform a measurement. When the secondary base station selects a terminal, it is determined that one radio bearer of the terminal belongs to a SN terminated MCG bearer type, that is, a RLC of this one radio bearer is in a MN network element. Measurement quantities required to be measured by the SN network management in this example are M5 and M7, both measurements are performed at the RLC entity, and both measurements are performed by the MN in this example. The secondary base station will thus send the activation information for measurement configuration to the main base station, to initiate the main base station to measure this radio access bearer.
An interface message used to convey the activation information for measurement configuration may be a new XnAP or X2AP message, such as an S-NG-RAN node initiated Trace start message. An existing message may also be used, such as S-NODE MODIFICATION REQUIRED message, in which the activation information for measurement configuration is carried.
The measurement configuration information may include following parameters:
If the MN uses NR to access, the SN transmits MDT measurement configuration information of NR-type obtained in operation 2 to the MN. If the MN uses EUTRA to access, the SN sends MDT measurement configuration information of EUTRA-type obtained in operation 2 to the MN.
In operation 3, the main base station performs an MDT measurement on a MN side. For example, after the main base station receives the message in the operation 2, the MN side performs the MDT measurement on the UE, for example, by using a TS38.314 protocol or a TS 28.552 protocol. The MN network element performs a measurement on M5, M7.
In operation 4, the main base station reports a measurement result to TCE. For example, the MN sends the measurement report on the MN to the TCE according to information about the trace collection entity obtained in the operation 2, and the TCE obtains an evaluation of a measurement result of the terminal on the MR-DC according to an MDT measurement result on the MN network element.
In an example embodiment, the SN network element triggering a management-based MDT measurement is used as an example, where the measurement object measured at this MDT is M6.

The MN and the SN may establish one SN terminated MCG bearer for a terminal.
In operation 1, a network management of the SN sends a management-based MDT measurement activation request to the secondary base station. For example, the network management of the SN configures different management-based MDT measurement activation request configurations for the SN and the MN, respectively, due to that radio access technologies used by the SN and the MN may be different. Referring to
An interface between a base station and the network management is used for the configuration, and the measurement configuration information configured by the SN may include following parameters:
In operation 2, the secondary base station sends activation information for measurement configuration to the main base station. For example, after a management-based MDT measurement request is received, the secondary base station selects a terminal satisfying the condition to perform a measurement. When the secondary base station selects a terminal, it is determined that one radio bearer of the terminal belongs to a SN terminated MCG bearer type, that is, a RLC of this one radio bearer is in a MN network element. A measurement required to be measured by the SN network management in this example is M6, which requires both the MN side and the SN side to initiate the measurement. For example, a latency on a PDCP layer and a transmission latency between the SN to the MN need to be calculated on the SN side, an air interface latency and a user plane processing latency on the MN side need to be calculated on the MN side. The secondary base station sends the activation information for measurement configuration to the main base station, to initiate the main base station to measure this radio access bearer.
An interface message used to transmit the activation information for measurement configuration may be a new XnAP or X2AP message, such as an S-NG-RAN node initiated Trace start message, or may be an existing message, such as S-NODE MODIFICATION REQUIRED message. The activation information for measurement configuration is carried in the above messages.
The measurement configuration includes following parameters:
If the MN is accessed by using the NR, the SN transmits MDT measurement configuration information of NR-type obtained in operation2 to the MN. If the MN uses the EUTRA, the SN sends MDT measurement configuration information of EUTRA-type obtained in operation2 to the MN.
In operation 3.1, the secondary base station performs the MDT measurement on the SN side, and the SN performs an MDT measurement for the UE according to the existing art.

In operation 3.2, the main base station performs an MDT measurement on a MN side; after the MN receives the message in the operation 2, the MN side performs the MDT measurement on the UE according to the existing art. For example, the MN side performs the MDT measurement on the UE by using a TS38.314 protocol or a TS 28.552 protocol. The MN network element performs a measurement on M6.
In operation 4.1 and operation 4.2, the main base station and the secondary base station reports measurement results to TCE, respectively. The MN sends the measurement report on the MN to the TCE according to the information about the trace collection entity obtained in the operation 2. The SN sends a measurement report on the SN to the TCE according to the information about the trace collection entity obtained in the operation 1.
The TCE obtains an evaluation of a measurement result of the terminal on the MR-DC according to an MDT measurement result on the SN network element and the MN network element.

The MN and the SN may establish one SN terminated split bearer for a terminal.
In operation 1, a network management of the SN sends a management-based MDT measurement activation request to the secondary base station.
For example, the network management of the SN configures different configurations for the SN and the MN respectively for management-based MDT measurement activation requests, due to that radio access technologies used by the SN and the MN may be different. Referring to
An interface between a base station and the network management is used for the configuration, and the measurement configuration information configured by the SN may include following parameters:
In operation 2, the secondary base station sends activation information for measurement configuration to the main base station. After a management-based MDT measurement request is received, the secondary base station selects a terminal satisfying the condition to perform a measurement. When the secondary base station selects a terminal, it is determined that one radio bearer of the terminal is a type of SN terminated split bearer, that is, this radio bearer includes two RLC entities, i.e., one of the two RLC entities is at the MN network element and the other one of the two RLC entities is at the SN. Measurements required to be performed by the SN network management in this example are M5 and M7, which require both the MN side and the SN side to initiate the measurement of the RLC entity. For example, the RLC on the SN side needs to calculate M5 and M7 on the SN side, and the RLC on the MN side needs to calculate M5 and M7 on the MN side. The secondary base station will thus send the activation information for measurement configuration to the main base station, to initiate the main base station to measure this radio access bearer. The interface message used for transmitting the activation information for measurement configuration may be a new XnAP or X2AP message, such as an S-NG-RAN node initiated Trace start message, or may be an existing message, such as an S-NODE MODIFICATION REQUIRED message.

A measurement required to be measured by the SN network management in this embodiment is M6, and it requires both the MN side and the SN side to initiate the measurement simultaneously. For example, a latency on a PDCP layer and a transmission latency between the SN to the MN need to be calculated on the SN side, an air interface latency and a user plane processing latency on the MN side need to be calculated on the MN side. The secondary base station will send the activation information for measurement configuration to the main base station, to initiate the main base station to measure this radio access bearer.

In the embodiments of the present application, the main base station sends a S-NODE ADDTITION REQUSET message carrying the SN terminated MCG bearer information through an Xn interface or an X2 interface, and the SN sends the S-NODE-RECONFIGURATION COMPLETE message to the MN after the SN has finished a configuration. The MN and the SN may establish an SN terminated MCG bearer for the terminal.
In operation 1, a network management of the SN sends a management-based MDT measurement activation request to the secondary base station. For example, the network management of the SN configures different configurations for management-based MDT measurement activation requests of the SN and the MN, respectively, due to that radio access technologies used by the SN and the MN may be different. Referring to
An interface between a base station and the network management is used for the configuration, and the measurement configuration information configured by the SN may include following parameters:
In operation 2, the secondary base station sends activation information for measurement configuration to the main base station. In the embodiments of the present application, after a management-based MDT measurement request is received, the secondary base station selects a terminal satisfying the condition to perform a measurement. When the secondary base station selects a terminal, it is determined that one radio bearer of the terminal is a type of a SN terminated MCG bearer, that is, a RLC of this one radio bearer is in a MN network element. Measurements required to be measured by the SN network management in this example are M5 and M7, both of which are performed at the RLC entity and are performed by the MN in this example. The secondary base station will thus send the activation information for measurement configuration to the main base station, to initiate the main base station to measure this radio access bearer.
An interface message used to transmit the activation information for measurement configuration may be a new XnAP or X2AP message such as an S-NG-RAN node initiated Trace start message, and may be an existing message such as an S-NODE MODIFICATION REQUIRED message, in both of which the activation information for measurement configuration is carried.
The measurement configuration information may include following parameters:
If the MN is accessed by using the NR, the SN transmits MDT measurement configuration information of NR-type obtained in operation 2 to the MN. If the MN uses EUTRA, the SN sends MDT measurement configuration information of EUTRA-type obtained in operation 2 to the MN.
In operation 3, the main base station performs an MDT measurement on a MN side. For example, after the main base station receives the message in the operation 2, the MN side performs the MDT measurement on the UE, for example, by using a TS38.314 protocol or a TS 28.552 protocol. The MN network element performs a measurement on M5, M7.
In operation 4, the main base station sends a measurement result to the secondary base station. An existing message may be also used to send the measurement result. For example, a result measured on the MN side is carried in an M-NODE MODIFICATION REQUEST message. A new message, such as M-NG-RAN node MDT Report, may also be used to carry the result measured on the MN side.
Information containing in the message includes one or a combination of:
Because the main base station outputs one measurement result at the end of each measurement period according to the configuration, and the main base station may send multiple messages containing multiple measurement results to the secondary base station.
In operation 5, the secondary base station sends all measurement results to TCE. The secondary base station combines the measurement results on the secondary base station and the main base station and then sends the combined measurement results to the TCE together. The secondary base station may also send the measurement result of the main base station directly to the TCE without being combined with the measurement result on the secondary base station.
A quality of experience (QOE) measurement is performed on the terminal side. The operator, when evaluating the quality of experience, often needs to provide the quality of service on the network side during a QOE measurement, to determine whether the degradation of the quality of experience is related to the quality of service on the terminal or the quality of service on the network side. The MDT measurement may serve as a measurement for assisting evaluation of QOE. The operator evaluates the quality of experience based on a report of the QOE measurement. Therefore, if the MDT measurement report and the QOE measurement report are not both on a same device, it is difficult for the operator to achieve a complete evaluation of the quality of experience. A measurement report for MDT is eventually sent by the base station to a TCE device, while a measurement report for QOE is eventually sent by the base station to a measurement collection entity (MCE) device, it is therefore necessary to send an MDT measurement result to the MCE device, where the MDT measurement result is used for assisting the evaluation of QOE. Secondly, in the existing art, the base station may support a split architecture, that is, one base station may be split into gNB-CU-CP, gNB-CU-UP, and gNB-DU, the three of which may independently perform an MDT measurement and independently report the measurement result to the TCE device. Herein, gNB refers to a next generation node B, CU refers to a control unit, CP refers to a control plain, UP refers to a user plain, and DU refers to a distributed unit. In the existing art, under a multi-connectivity architecture, the MDT measurement report of the main base station and the MDT measurement report of the secondary base station may also be independently sent to the TCE device. Therefore, it needs to address how to send the MDT measurement result for assisting the evaluation of QOE to the MCE device under the split architecture and the multi-connectivity architecture.
