In order to understand the performance of mobile networks, mobile network builders or network operators usually need to drive a car along a fixed line to collect a series of measurements that reflect the current network performance, such as downlink signal quality/interference. Based on the measurements collected about network performance, the network optimization team can then make adjustments to the deployment of mobile network equipment, signal strength, and antenna angle settings to improve mobile network performance and user satisfaction. However, the disadvantage of this method is that with the expansion of the scale of the mobile network, the drive test will become more time-consuming and labor-intensive, which is not conducive to the timely adjustment of network deployment by the mobile operator, and consumes a large cost.

Based on this, a signal acquisition method called Minimization of Drive Test (MDT) is introduced into the mobile network. Its core idea is to enable many user terminals to report their signal acquisition volume under the condition of obtaining the terminal's permission. . On the premise that the number of terminals is sufficient, the network can quickly and economically obtain information about network performance in the area. This method of collecting the network performance of terminals in certain target areas is called management-based MDT (management-based MDT). . In addition, MDT can also be used to help the network collect data related to network performance of a specific terminal (for example, the terminal user often complains about poor network performance). This MDT collection method is called signal-based MDT (signaling-based MDT).

The target terminal performing MDT may be in a connected (connected) state, an idle (Idle) state or an inactive (Inactive) state. But the MDT configuration signaling must be sent by the network to the terminal when the terminal is in the connected state. When the network is configured with immediate MDT, the terminal will report the measurement quantity collected by the terminal in the connected state in the connected state. Alternatively, when the network is configured with a logged (logged) MDT, the terminal will report the measurement quantity recorded when returning to the idle state to the network when the connected state is restored.

In some embodiments, the MDT configuration can be sent to the terminal through the core network control plane network element or the network management (OAM), and after the terminal completes the measurement collection, it generates an MDT report and reports it to the base station, and then the base station sends it to an independent MDT Data analysis network elements, for example, trace collection entities (Trace Collection Entity, TCE).

In some embodiments, different radio access technologies (Radio Access Technology, RAT) may correspond to corresponding MDT configurations. The following examples illustrate the specific content of the MDT configuration corresponding to 5G or NR and the MDT configuration corresponding to LTE or 4G.

Optionally, the MDT configuration corresponding to 5G may include at least one of the following information elements (Information Element, IE):

Trace area reference, e.g. traceReference-r16;

Trace recording session reference, such as traceRecordingSessionRef-r16;

TCE identifier, such as tce-Id-r16;

absolute time, e.g. absoluteTimeInfo-r16;

Area configuration, such as areaConfiguration-r16;

Public Land Mobile Network (PLMN) identity list, for example, plmn-IdentityList-r16;

Bluetooth name list, such as bt-NameList-r16;

List of wireless LAN names, such as wlan-NameList-r16;

List of sensor names, such as sensor-NameList-r16;

Recording duration, such as loggingDuration-r16.

Optionally, the area configuration in the MDT configuration corresponding to 5G may include at least one of the following:

Serving cell area configuration, such as areaConfigForServing-r16;

Neighbor cell area configuration, such as areaConfigForNeighbour-r16.

Optionally, the serving cell area configuration is used to configure a target area that needs to perform measurement recording, for example, it may include at least one of the following:

Cell global list, such as cellGlobalIdList-r16;

Tracking area code list, such as trackingAreaCodeList-r16;

A list of tracking area identities, e.g. trackingAreaIdentityList-r16.

Optionally, the neighbor cell area configuration is used to configure a measurement object to be recorded (it may be a measurement object of NR or LTE, or may also be a measurement object of other RATs), for example, it may include at least one of the following:

Downlink carrier frequency, such as dl-CarrierFreq;

Band list, such as frequencyBandList;

A list of cells, such as cellList.

It should be noted that if the neighbor cell area configuration is configured, it indicates the frequency at which the UE requests to perform measurement logging for the neighbor cells. The UE shall perform measurement volume recording on the frequency in the SIB4 of the current serving cell, and the downlink carrier frequency and at least one frequency band indication of the serving cell are also included in the neighbor cell area configuration. If not configured, the UE may perform measurement logging for all neighbor cells.

Optionally, the global cell identity may be part of bits in a cell global identity (Cell Global Identity, CGI).

Optionally, the tracking area identifier may include a PLMN identifier and a tracking area code.

Optionally, the MDT configuration corresponding to 4G may include at least one of the following IEs:

Trace area reference, for example, traceReference-r10;

Trace recording session reference, such as traceRecordingSessionRef-r10;

TCE identifier, such as tce-Id-r10;

absolute time, e.g. absoluteTimeInfo-r10;

Area configuration, such as areaConfiguration-r10, or areaConfiguration-v1130;

Recording duration, such as loggingDuration-r10;

logging interval, e.g. loggingInterval-r10;

List of PLMN identities, for example, plmn-IdentityList-r11;

Bluetooth name list, such as bt-NameList-r15;

List of wireless LAN names, such as wlan-NameList-r15.

Optionally, the area configuration in the MDT configuration corresponding to 4G may include at least one of the following:

Cell global list, such as cellGlobalIdList-r10;

A list of tracking area codes, such as trackingAreaCodeList-r10, or trackingAreaCodeList-v1130.

It can be seen that the MDT configurations corresponding to 5G and LTE may be different. When the terminal is in a cross-RAT dual connectivity scenario, both the MN and the SN can send the MDT configuration of the RAT to which they belong to the terminal. In this case, how to report the measurement quantity of the terminal to improve the network performance is an urgent problem to be solved.

FIG. 2 is a schematic flowchart of a registered method 200 for minimizing drive tests according to an embodiment of the present application. The method 200 may be executed by a terminal device in the communication system shown in FIG. 1 , and as shown in FIG. 2 , the method 200 may include at least some of the following contents:

S210, the terminal device records the first measurement quantity according to the first MDT configuration corresponding to the first radio access technology RAT, and/or records the second measurement quantity according to the second MDT configuration corresponding to the second RAT;

S220. Generate a first MDT report based on the recorded first measurement quantity, and/or generate a second MDT report based on the recorded second measurement quantity.

In this embodiment of the present application, the terminal device is located in an area covered by a cell based on the first RAT, and is located in an area covered by a cell based on the second RAT.

Optionally, the first RAT may be LTE or 4G, and the second RAT may be NR or 5G; or, the second RAT may be LTE or 4G, and the first RAT may be NR or 5G. Alternatively, the first RAT and the second RAT may also be two other different types of radio access technologies, and the present application is not limited thereto.

The MDT configuration corresponding to NR here may include some or all of the IEs in the MDT corresponding to 5G described above, or may be increased, decreased, or adjusted with the evolution of the standard, which is not specifically limited in this application.

The MDT configuration corresponding to LTE here may include some or all of the IEs in the MDT corresponding to 4G described above, or may be increased, decreased, or adjusted with the evolution of the standard, which is not specifically limited in this application.

When the terminal device is located in an area covered by two RATs, the terminal device may record the measurement amount based on the MDT configuration corresponding to at least one of the two RATs, and may further generate a logged measurement report (logged measurement report) according to the recorded measurement amount. measurement report), so that after entering the connected state, the generated logged measurement report can be reported to the network.

Optionally, the measurement quantity may include, for example, information of a measurement object to be measured, such as downlink carrier frequency, frequency band information, cell, and the like.

In some embodiments, the terminal device resides in the first cell, and the terminal device may determine, according to the RAT type of the first cell, which MDT configuration is used to record the measurement quantity. For example, if the first cell is a cell based on the first RAT, the terminal device may record the measurement amount according to the first MDT configuration corresponding to the first RAT. Alternatively, if the first cell is a cell of the second RAT, the terminal device may record the measurement amount according to the second MDT configuration corresponding to the second RAT.

In other embodiments, the terminal device resides in a first cell, and the first cell is a cell based on the first RAT, and the terminal device may determine the MDT configuration record corresponding to the first RAT The first measurement quantity, and the second measurement quantity may also be recorded according to the second MDT configuration corresponding to the second RAT under certain conditions.

As an embodiment, the terminal device may determine, according to the channel quality of the cell based on the second RAT, whether to record the second measurement quantity according to the second MDT configuration corresponding to the second RAT.

For the convenience of description and illustration, it is assumed that the terminal device is currently in the area where the first cell and the second cell overlap, and the terminal device is currently camping on the first cell, that is, the first cell is called a camping cell, and the The second cell is a non-resident cell, and the first cell and the second cell correspond to the first RAT and the second RAT, respectively.

In this case, the terminal device may determine, according to the channel quality of the second cell, whether to record the second measurement quantity according to the second MDT configuration corresponding to the second RAT. For example, if the channel quality based on the second cell is higher than the first threshold, it may be considered that there is a cell based on the second RAT near the first cell, and the terminal device determines the second MDT corresponding to the second RAT. Configure to record the second measurement. For another example, if the channel quality of the second cell is lower than or equal to the first threshold, it may be considered that there is no cell based on the second RAT near the first cell, and the terminal device determines that the cell based on the second RAT does not exist near the first cell. The second MDT configuration records the second measurement quantity.

Optionally, the channel quality of the cell in this embodiment of the present application may be represented by any of the following measurement results:

Received Signal Strength Indication (RSSI);

Reference Signal Receiving Power (RSRP);

Reference Signal Receiving Quality (RSRQ);

Signal to Interference plus Noise Ratio (SINR).

Correspondingly, the first threshold is a threshold related to the measurement result. For example, when the channel quality is represented by RSRP, the first threshold may be an RSRP threshold, or when the channel quality is represented by RSRQ, the first threshold may be an RSRQ threshold.

In some embodiments, the first threshold may be a network device configuration. For example, the network device may be configured through radio resource control (Radio Resource Control, RRC), or may also be configured through other downlink messages or signaling. Not limited to this.

In other embodiments, the first threshold may be determined by the terminal device itself. For example, the terminal device may use the channel quality of the first cell plus a certain offset as the first threshold, so The offset is, for example, -3dB, or can also be adjusted according to actual needs, and the present application is not limited to this.

As another embodiment, the terminal device may determine, according to the indication of the network device, whether the second MDT configuration corresponding to the second RAT records the second measurement quantity.

For example, the network device may instruct the terminal device whether to simultaneously record measurement quantities according to the MDT configurations corresponding to the two RATs when the terminal device is in an area covered by two RATs at the same time.

As an example, the indication of the network device may be 1-bit indication information, which is used to indicate that when it is in an area covered by two kinds of RATs at the same time, the measurement amount is recorded according to the MDT configurations corresponding to the two kinds of RATs at the same time, or The measurement amount is recorded only according to the MDT configuration of the RAT corresponding to the currently camped cell.

As another example, the indication of the network device may be 1-bit indication information, which is used to indicate that when it is in an area covered by two RATs at the same time, when a specific condition is met, the indication is performed according to the MDT configurations corresponding to the two RATs at the same time. The measurement amount is recorded, or the measurement amount is recorded only according to the MDT configuration of the RAT corresponding to the currently camping cell.

Optionally, the specific condition may be the channel quality condition described above. For example, when the channel quality of the non-resident cell of the terminal device is higher than the first threshold, the measurement quantity is recorded according to the MDT configurations corresponding to the two RATs, and the channel quality of the non-resident cell is lower than or equal to the When the first threshold is set, the measurement amount is recorded only according to the MDT configuration corresponding to the RAT of the camping cell.

Optionally, the specific condition may be that the first cell belongs to the target area of the area configuration in the second MDT. As mentioned above, the area configuration may configure the target area for which measurement quantity recording needs to be performed, and the target area may be configured in the cell global identification list or the tracking area identification list. For example, when the global cell identifier of the first cell is in the cell global identifier list, or the tracking area identifier to which the first cell belongs is in the tracking area identifier list, the terminal device determines that according to the two RATs simultaneously The corresponding MDT configuration records the measurement amount; or when the global cell identifier of the first cell is not in the global cell identifier list, and the tracking area identifier to which the first cell belongs is not in the tracking area identifier list, the terminal The device determines to record the measurement quantity only according to the MDT configuration of the RAT corresponding to the currently camped cell.

As shown in FIG. 3 , the terminal device currently resides in cell 1, cell 1 is an NR cell, there is an overlapping area between cell 1 and cell 2, and cell 2 is an LTE cell.

In an implementation manner, the terminal device may record the measurement amount according to the MDT configuration corresponding to LTE when the signal quality of cell 2 is greater than the first threshold.

In another implementation manner, when cell 1 belongs to the target area in the MDT configuration corresponding to LTE, the terminal device may record the measurement amount according to the MDT configuration corresponding to LTE.

In yet another implementation manner, the terminal device may record the measurement amount according to the MDT configuration corresponding to LTE when the signal quality of cell 2 is greater than the first threshold and cell 1 belongs to the target area in the MDT configuration corresponding to LTE.

Optionally, the specific condition may be a judgment condition related to geographic location. For example, if the terminal device is in an area where network deployment is mature, the network device may configure the terminal device to only configure the MDT according to the RAT corresponding to the currently residing cell. Record the measurement quantity, or, if the terminal device is in an area where network deployment is immature, the network device may configure the terminal device to simultaneously record the measurement quantity according to the MDT configurations corresponding to the two RATs.
