Before introducing the solutions shown in the subsequent embodiments of the present application, several terms and concepts involved in the present application are first introduced.

1) Minimum drive test MDT

MDT refers to the minimum drive test or the minimum drive test, and its main purposes are as follows:

a. Reduce the drive test overhead and shorten the optimization period, thereby reducing the network optimization and maintenance costs of mobile communication operators;

b. It can collect the measurement information of the whole area (such as narrow roads, forests, private places, etc.) that cannot be carried out by traditional drive tests. Therefore, the network performance can be evaluated more objectively, and the results of the network evaluation can be closer to the user experience. for higher user satisfaction.

The MDT mode is divided into Immediate MDT and Logged MDT.

Among them, Immediate MDT requires the terminal device to measure in the connected state, and immediately report the measurement report to the network side device (such as gNB) after the measurement is completed.

Logged MDT requires the terminal device to measure and store in the idle state (IDLE state) or inactive state (INACTIVE state) according to the configuration parameter information, and report the measurement results to the network side device after entering the connected state (Connected state).

The activation of Immediate MDT and Logged MDT is divided into management-based activation and signaling-based activation. Before activating the MDT, the user needs to hand over the consent (license) to the core network. For management-based MDT, the user permission information is issued by the core network to the Radio Access Network (RAN), and the RAN instructs the terminal equipment in the area to activate MDT according to the user information; for signaling-based MDT, it is through The core network instructs a specific terminal device to activate the MDT without sending the user permission information to the RAN.

2) Dual connection

Dual-Connectivity (DC) is an important technology introduced by the 3rd Generation Partnership Project (3GPP) organization. Through dual connectivity technology, Long Term Evolution (LTE) macro and small cells can use the non-ideal backhaul (non-ideal backhaul) X2 interface to implement carrier aggregation, thereby providing users with higher rates, and using macro / Micro-networking improves spectral efficiency and load balancing. A terminal device that supports dual connections can connect to two base stations at the same time, increasing the throughput of a single user.

During the deployment of 5G networks, 5G cells can be used as macro-coverage independent networking, or as small cells to enhance coverage and capacity of existing LTE networks. No matter which networking method is adopted, the dual-connection technology can be used to realize the interconnection of LTE-5G systems, thereby improving the wireless resource utilization of the entire mobile network system, reducing the delay of system handover, and improving user and system performance. Based on the LTE dual-connection technology, the 3GPP organization defines the dual-connection technology of LTE and 5G. LTE-5G dual connectivity is a key technology for operators to achieve LTE and 5G converged networking and flexible deployment scenarios. In the early stage of 5G, rapid deployment can be achieved based on the existing LTE core network, and in the later stage, the joint networking of LTE and 5G can be used to achieve comprehensive network coverage, improve the wireless resource utilization of the entire network system, reduce the system switching delay, and increase the number of users. and system performance.

3) Instant MDT in dual connection scenarios

The solution for supporting MDT in the dual-connection scenario is relatively complicated, and the immediate MDT reporting in the scenario of Evolved Universal Terrestrial Radio Access-NR DC (EN-DC) involved in this application In the scheme, the master node (Master Node, MN) is the access node in the E-UTRA network, and the secondary node (Secondary Node, SN) is the access node in the NR network.

The MDT measurement configuration in the EN-DC scenario is as follows:

Please refer to FIG. 2 , which shows a schematic diagram of management-based MDT reporting provided by an embodiment of the present application. As shown in FIG. 2, for the management-based Immediate MDT, the Operation Administration and Maintenance (OAM) entity 21 directly configures the MDT configuration information (MDT configuration) independently for the primary node 22 and the secondary node 23; SRB1/SRB2 submits the MN-related measurement results to the master node 22, and if SRB3 is configured, the UE can submit the SN-related measurement results to the secondary node 23 through SRB3.

Please refer to FIG. 3 , which shows a schematic diagram of signaling-based MDT reporting provided by an embodiment of the present application. As shown in FIG. 3, for the immediate MDT based on signaling, the mobility management function (Mobility Management Entity, MME) entity 31 submits all the MDT configuration information of the MN and SN to the master node 32, and the master node 32 sends the MDT configuration information through the X2 interface. The NR MDT configuration information is forwarded to the secondary node 33; when performing MDT reporting, the terminal device 34 needs to submit the MN and SN-related measurement results to the master node 32 through SRB1/SRB2, and the master node 32 The SN-related measurement results are forwarded to Secondary node 33.

In the Immediate MDT in the above dual-connectivity scenario, there are two ways to report the measurement results. The first is that when SRB3 is configured, the UE reports the corresponding measurement results to the MN and SN respectively; the second is that when SRB3 is configured At SRB3, the UE reports all the measurement results corresponding to the MN and the SN to the MN, and the MN transfers the measurement results related to the SN to the SN. However, this scheme has the following problems:

During the Immediate MDT reporting process, when there is a problem in the uplink transmission between the terminal device and the MN, the Immediate MDT cannot be reported in time or the report fails, resulting in the master node MN being unable to obtain the real-time MDT data of the terminal device in time. In view of the above problems, subsequent embodiments of the present application provide an MDT reporting solution, which can ensure the accuracy of the MDT data reported by the terminal device to the network side.

Please refer to FIG. 4 , which shows a flowchart of a measurement reporting method provided by an embodiment of the present application. The method may be executed by a terminal device, where the terminal device may be a terminal in the network architecture shown in FIG. 1 . The method may include the following steps:

Step 402 , when the terminal device does not have the conditions for performing uplink data transmission with the master node, report the first real-time minimum drive test data to the secondary node in the dual-connectivity scenario.

Please refer to FIG. 5 , which shows a flowchart of a measurement reporting method provided by an embodiment of the present application. The method can be executed by a wireless access node, and the wireless access node is a terminal device in a dual-connection scenario. A secondary node; wherein, the above-mentioned wireless access node may be a base station in the network architecture shown in FIG. 1 . The method may include the following steps:

Step 501: Receive the first real-time minimum drive test data sent by the terminal device when it does not have the condition for uplink data transmission with the master node in the dual-connection scenario; the first real-time minimum drive test data is the pair of The real-time minimum drive test data of the master node.

Step 502: Send the first real-time minimum drive test data to the master node.

To sum up, in the solutions shown in the embodiments of the present application, for a terminal device in a dual-connection scenario, when there is real-time MDT data that needs to be reported to the master node in the terminal device, if the relationship between the terminal device and the master node does not satisfy the The condition of uplink data transmission, the terminal device reports the real-time MDT data to the secondary node in the dual-connection scenario, and the secondary node transmits the real-time MDT data to the master node, so that the real-time MDT data corresponding to the master node can be reported to the master node in time. Master node, improve the accuracy of MDT data reported by terminal equipment to the master node in dual connection.

Please refer to FIG. 6 , which shows a schematic diagram of a measurement reporting process provided by an embodiment of the present application. As shown in FIG. 6 , the terminal device 601 is in a dual-connection scenario and establishes connections with the master node 602 and the secondary node 603 at the same time, and the terminal device 601 performs real-time MDT measurements on the primary node 602 and the secondary node 603 .

In FIG. 6, the terminal device 601 performs real-time MDT measurement on the master node 602, and after obtaining the first real-time MDT data (step S1), it detects that it does not have the conditions for uplink data transmission with the master node 602 (step S2), At this time, the terminal device 601 reports the first real-time MDT data to the secondary node 603 (step S3), and after receiving the first real-time MDT data, the secondary node 603 sends the first real-time MDT data to the master node 602 (step S4). ), so that when the uplink transmission between the terminal device 601 and the master node 602 is not smooth, the real-time MDT data of the master node 602 can also be reported to the master node 602, so that the terminal device can report the MDT data to the master node in the dual connection. accuracy.

Please refer to FIG. 7 , which shows a flowchart of a measurement reporting method provided by an embodiment of the present application. The method can be performed by a terminal device and a wireless access node, and the wireless access node includes a dual connection where the terminal device is located. The primary node and the secondary node in the scenario; wherein, the above-mentioned terminal device may be a terminal in the network architecture shown in FIG. 1 ; the wireless access node may be a base station in the network architecture shown in FIG. 1 . As shown in Figure 7, the method may include the following steps:

Step 701, the terminal device establishes dual connections with the primary node and the secondary node.

In the embodiment of the present application, in a communication system supporting dual connectivity, when a terminal device enters a connected state, it establishes a connection with the primary node and the secondary node at the same time, and the terminal device is in a dual connectivity scenario at this time.

In a possible implementation manner, the above-mentioned master node is an evolved universal radio access network, also referred to as an access node in an evolved universal mobile communication system terrestrial radio access E-UTRA network, and the secondary node is a new air interface An access node in an NR network.

In another possible implementation manner, the above-mentioned master node is an access node in the NR network, and the secondary node is an access node in the E-UTRA network.

In another possible implementation manner, the primary node and the secondary node are both access nodes in the NR network; or, the primary node and the secondary node are both access nodes in the E-UTRA network.

This embodiment of the present application does not limit the networks to which the primary node and the secondary node respectively belong.

Step 702, the terminal device performs real-time MDT measurement on the master node to obtain first MDT data.

In the embodiment of the present application, after the terminal device establishes dual connections with the master node and the slave node, the network side performs MDT configuration on the master node and the slave node, so as to configure the reporting method of MDT data of the terminal device.

For example, in a possible implementation manner, the network management device configures the MDT configuration for the master node and the slave node respectively. For example, taking the above dual-connection scenario as an EN-DC scenario, the OAM entity directly configures the MDT configuration of the E-UTRA network independently for the master node, and does not independently configure the MDT configuration of the NR network for the slave node; or, the OAM entity is the master node. Configure the MDT configuration of the E-UTRA network and the MDT configuration of the NR network, and configure the MDT configuration of the E-UTRA network and the MDT configuration of the NR network for the secondary node.

In another possible implementation manner, the network management device configures the MDT configuration for the master node, and the master node sends the MDT configuration corresponding to the slave node to the slave node. For example, taking the EN-DC scenario as an example, the MME entity configures the MDT configuration of the E-UTRA network and the MDT configuration of the NR network to the master node, and the master node forwards the NR MDT configuration to the slave node through the X2 interface , or, the master node forwards the MDT configuration of the E-UTRA network and the MDT configuration of the NR network to the slave node through the X2 interface.

In another possible implementation manner, the network management device configures the MDT configuration for the secondary node, and the secondary node sends the MDT configuration corresponding to the primary node to the primary node. For example, taking the above dual connectivity scenario as an EN-DC scenario, the Core Access and Mobility Management Function (AMF) entity configures the MDT configuration of the E-UTRA network and the MDT configuration of the NR network to the auxiliary Node, the secondary node forwards the E-UTRA MDT configuration to the primary node through the X2 interface, or the secondary node forwards the MDT configuration of the E-UTRA network and the MDT configuration of the NR network to the primary node through the X2 interface.

After the network management device configures the MDT configuration for the primary node and the secondary node, when the terminal device is selected as the terminal for real-time MDT measurement, the terminal device can perform real-time MDT measurement on the primary node and secondary node to obtain real-time MDT data. The real-time MDT data obtained by the terminal device performing MDT measurement on the master node is the above-mentioned first real-time MDT data.

In a possible implementation manner, when the terminal device performs MDT measurement on the secondary node, the obtained instant MDT data is the second instant MDT data.

Step 703, when the terminal device does not have the conditions for performing uplink data transmission with the master node, and there is a designated wireless signaling bearer (Signaling Radio Bearer, SRB) between the terminal device and the secondary node, the terminal device passes the designated SRB, The first real-time MDT data is reported to the secondary node; correspondingly, the secondary node receives the first real-time MDT data.

In this embodiment of the present application, when there is the first real-time MDT data to be uploaded in the terminal device, the terminal device can detect whether the conditions for uplink data transmission with the master node are satisfied, and if it detects that the uplink data transmission with the master node is satisfied If the conditions for data transmission are not satisfied, the terminal device further determines whether there is a designated SRB between the terminal device and the auxiliary node. If there is a designated SRB between the terminal device and the auxiliary node, the terminal device reports the first real-time SRB to the auxiliary node through the designated SRB. MDT data.

Correspondingly, the secondary node also receives, through the designated SRB, the first real-time minimum drive test data sent by the terminal device when it does not have the conditions for uplink data transmission with the primary node.

In a possible implementation manner, if the terminal device detects that the conditions for uplink data transmission with the master node are satisfied, the terminal device reports the first real-time MDT data to the master node.

In a possible implementation manner, when the terminal device detects at least one of the following conditions, it may determine that it does not have the conditions for uplink data transmission with the master node:

1) There is no resource for uplink transmission to the master node;

In this embodiment of the present application, if the terminal device is not currently allocated or preempts the resources for uplink transmission to the master node, the terminal device cannot perform uplink transmission to the master node, and at this time, the terminal device does not have the ability to communicate with the master node. Conditions for upstream data transmission.

2) The master node is out of synchronization in the uplink;

In the embodiment of the present application, when the terminal device and the master node are out of synchronization in uplink, the terminal device cannot accurately perform uplink transmission to the master node. At this time, the terminal device may determine that it does not have the ability to perform uplink data transmission with the master node. condition.

3) The network has repeatedly fed back the NACK response of the uplink data sent by the terminal device to the master node that cannot be successfully decoded;

In this embodiment of the present application, when the network feeds back NACK responses multiple times to indicate that the uplink data sent by the terminal device to the master node cannot be successfully decoded, it means that the link quality of the uplink from the terminal device to the master node is poor ( For example, the uplink is severely interfered, or the terminal device is far away from the master node, or the transmit power of the terminal device is limited, etc.), at this time, the terminal device can determine that it does not have the ability to perform uplink communication with the master node.

The conditions are not limited in this application.

In a possible implementation manner, the above designated SRB is SRB3.

For example, taking the above dual-connection scenario as an EN-DC scenario, the terminal device can establish SRB1 or SRB2 with the master node, and can establish SRB3 with the secondary node. At SRB3, the terminal device may report the first real-time MDT data to the secondary node.

In another possible implementation manner, when the terminal device does not have the conditions for performing uplink data transmission with the master node, and the designated SRB does not exist between the terminal device and the secondary node, the terminal device The designated SRB is established with the secondary node.

Correspondingly, when the secondary node receives the first real-time minimum drive test data sent by the terminal device, it receives the data sent by the terminal device when it does not have the conditions for uplink data transmission with the primary node. and obtaining the first real-time minimum drive test data from the measurement report of the network corresponding to the secondary node.

For example, in the case where the terminal device performs real-time MDT measurement on the master node and the slave node respectively, the terminal device can report the first real-time MDT data to the slave node through the measurement report of the network corresponding to the slave node; that is, when the terminal device needs When reporting the first MDT data and the second MDT data to the secondary node respectively, the two MDT data are reported through the same measurement report, thereby realizing multiplexing of the existing measurement reports and improving the utilization rate of uplink resources.

In a possible implementation manner, when the terminal device reports the first real-time minimum drive test data to the secondary node through the measurement report of the network corresponding to the secondary node, the measurement report of the network corresponding to the secondary node includes the primary network and the first real-time minimum drive test data corresponding to the measurement flag of the main network; the main network is the network corresponding to the main node.

In an exemplary solution, taking the above-mentioned dual-connection scenario as an EN-DC scenario as an example, when the terminal device detects that there is a problem in the uplink transmission with the master node, it considers that the real-time MDT measurement result related to the master node cannot be successfully reported to the master node. The master node, if there is SRB3 between the terminal equipment and the secondary node, the terminal equipment reports the following content according to the NR signaling structure:

A) The NR measurement results (NR-MeasResults) of the secondary node are recorded according to the MeasResults method specified in the 38.331 protocol;

B) The E-UTRA measurement results (Eutra-MeasResults) of the master node are recorded according to the MeasResults method specified in the 36.331 protocol;

In the measurement report of the network corresponding to the secondary node, the above content structure is as follows:

Step 704, the secondary node sends the first real-time MDT data to the primary node.

In this embodiment of the present application, after receiving the first instant MDT data, the secondary node may forward the first instant MDT data to the master node, so that the master node can obtain the first instant MDT data immediately.

In a possible implementation manner, the secondary node sends the first real-time minimum drive test data to the primary node through the X2 interface with the primary node.

In this embodiment of the present application, the secondary node and the primary node are connected through an X2 interface, and the secondary node can transmit the real-time MDT data of the primary node to the primary node through the X2 interface.

In another possible implementation manner, the secondary node sends the first instant minimum drive test data to the mobility management entity MME through the core access and mobility management function AMF entity, and the MME sends the first instant minimum drive test data to the mobility management entity MME. The measurement data is sent to the master node.

For example, taking the above dual connectivity scenario as an EN-DC scenario, the secondary node is an NR base station (such as a gNB), and the primary node is an E-UTRA base station (such as an eNB), after receiving the above-mentioned first MDT data, the gNB can successively The first MDT data is sent to the eNB through the AMF and the MME in the core network as a relay.

In another possible implementation manner, the secondary node sends the first instant minimum drive test data to the AMF through the MME, and the AMF sends the first instant minimum drive test data to the master node.

For example, if the secondary node is an E-UTRA base station (such as an eNB), and the master node is an NR base station (such as a gNB), as an example, after receiving the above-mentioned first MDT data, the eNB can successively pass the MME and AMF in the core network as the Transit, and send the first MDT data to the gNB.

In another possible implementation manner, the secondary node sends the first instant minimum drive test data to the AMF, and the AMF sends the first instant minimum drive test data to the master node.

For example, if both the secondary node and the master node are NR base stations (such as gNBs), as an example, after gNB1 receives the above-mentioned first MDT data, it can use the AMF in the core network as a relay to send the first MDT data to gNB2.

In another possible implementation manner, the secondary node sends the first real-time minimum drive test data to the MME, and the MME sends the first real-time minimum drive test data to the master node.

For example, if both the secondary node and the master node are E-UTRA base stations (such as eNBs), as an example, after receiving the above-mentioned first MDT data, eNB1 can use the MME in the core network as a relay to send the first MDT data to the eNB2.
