[0002] In related technologies, Radio Access Network (RAN)-initiated Measurement and Data Collection (MDT) mainly falls into two scenarios: management-based MDT and signaling-based MDT. In practical applications, because idle or inactive UEs move across Public Land Mobile Networks (PLMNs), on the one hand, when a UE moves to a PLMN not listed in the core network's PLMN list, if the base station requests the UE to collect measurement values, the UE will report an empty report; on the other hand, the UE cannot understand the specific network management regulations in real time, which may lead to the UE being unable to measure / collect / report measurement values, resulting in erroneous reports. Summary of the Invention
[0003] In view of this, this application aims to provide an MDT configuration method, base station, UE, storage medium, and computer program product that can improve the accuracy of the reports submitted by the UE when performing MDT measurements.

[0018] The measurement unit is used to measure the quantity after receiving the second configuration information.
[0019] Fifthly, this application provides a first base station, the first base station comprising: a first processor and a first memory; when the first processor executes the running program stored in the first memory, it implements the MDT configuration method of the first base station described above.
[0020] Sixthly, this application provides a UE, the UE comprising: a second processor and a second memory; the second processor implements the above-described MDT configuration method on the UE side when executing a running program stored in the second memory.
[0021] In a seventh aspect, this application provides a storage medium storing a computer program thereon, which, when executed by a processor, implements the MDT configuration method on the first base station side, or, when executed by a processor, implements the MDT configuration method on the UE side.

This avoids the occurrence of erroneous reporting caused by the inconsistency between the OAM configuration in the PLMN and the core network configuration information received by the base station, and improves the accuracy of the reports reported by the UE when performing MDT measurements.

[0031] To gain a more detailed understanding of the features and technical content of the embodiments of this application, the technical solutions of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The accompanying drawings are for reference only and are not intended to limit the embodiments of this application.

The terminology used in the embodiments of this application is for the purpose of describing the embodiments of this application only and is not intended to limit this application.
[0033] In the following description, references to "some embodiments" refer to a subset of all possible embodiments. It is understood that "some embodiments" may be the same or different subsets of all possible embodiments and may be combined with each other without conflict. It should also be noted that the terms "first / second / third" used in the embodiments of this application are merely for distinguishing similar objects and do not represent a specific ordering of objects. It is understood that "first / second / third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.
[0034] MDT technology obtains relevant parameters needed for network optimization by reporting measurement reports from mobile phones, thereby reducing the network optimization and maintenance costs for operators.
[0035] MDT measurement currently has two main modes: Logged MDT and Immediate MDT.
[0036] For Logged MDT, the UE, in connected mode, receives configuration parameters (such as measurement quantities) sent by the network through a LoggedMeasurementConfiguration message. Figure 1 As shown, the Evolved UMTS Terrestrial Radio Access Network (E-)UTRAN or New Radio (NR) sends configuration parameters to the UE through LoggedMeasurementConfiguration in the connected state. The UE records measurements in the idle or inactive state and reports the corresponding measurement quantities when it re-enters the connected state.
[0037] For Immediate MDT, the base station configures the UE to perform measurements through the current Radio Resource Control (RRC) signaling process. The UE performs the measurement in the connected state and reports the measurement report to the network after the measurement is completed.
[0038] In related technologies, the initiation of MDT measurement collection by Next Generation Radio Access Network Nodes (NG-RAN nodes) mainly falls into two scenarios. One scenario is Management-based MDT, primarily targeting UEs within a certain area; the other is Signalling-based MDT, primarily targeting a specific UE. When the base station needs to initiate MDT measurement collection, it needs to check the network management configuration to determine whether specific measurements within a specific area (e.g., measurements that can be directly collected according to local laws and regulations) require user consent. If user consent is not required, the base station can directly collect the data without user consent. If user consent is required, for Management-based MDT, the core network will decide whether to provide information allowing the base station to configure MDT based on user consent and roaming status. This information is used to instruct the NG-RAN node (i.e., the base station) whether to allow MDT configuration for that user. In 5G, this information is represented by a Management Based MDTPLMN list. For Signaling Based MDT, the core network will not initiate MDT measurement collection for a specific UE unless the user agrees.
[0039] After receiving the activation information of Management-based MDT, when the base station adopts the logged-MDT mode, it sends a PLMN list to the UE via RRC messages. The PLMN list consists of PLMNs that allow the UE to perform measurement collection. Idle or inactive UEs will move across PLMNs. When a UE moves to a PLMN that is not in the core network's PLMN list (i.e., if the PLMN is not in the list, the UE is not allowed to perform measurement collection), if the base station requests the UE to collect measurement values, the UE will report an empty report.
[0040] In actual network deployment, measurement collection in a particular region is also affected by network management configuration. Network management may configure whether base stations need to check user consent for specific measurement values. For example, a local network management system might stipulate that base stations can directly initiate MDT measurement collection and reporting without checking user consent, and that base stations can directly select UEs without relying on the Management-based MDTPLMN List IE sent by the core network. In other words, if the local network management has clear regulations, the network management configuration can be directly considered, and measurement collection can proceed without referring to user consent in the PLMN list. However, considering that a UE performing LoggedMDT measurements might move to a PLMN not on the list, and the UE cannot learn about the local network management regulations in real time, this could lead to the UE being unable to measure / collect / report measurement values, resulting in erroneous reports.
[0041] To address the aforementioned issues, this application proposes a method for MDT configuration on the base station side. By configuring the UE on the base station side, the UE can obtain the latest user consent information in advance. This allows the UE to perform MDT data measurement, collection, and reporting within the corresponding PLMN. The specific implementation scheme of this application is as follows:
[0042] This application provides an MDT configuration method, such as... Figure 2 As shown, when applied to a first base station, the method may include:
[0043] S201. Obtain the first configuration information and / or PLMN list and / or OAM configuration information.
[0044] In this embodiment of the application, the first configuration information includes the measurements to be collected, the recording interval for each measurement, and the reporting type for each measurement.
[0045] In this embodiment of the application, the OAM configuration information can be a list of PLMNs configured by OAM, which can be understood as the measurements that the user agrees to collect in each PLMN configured by OAM.
[0046] In this embodiment of the application, obtaining the first configuration information and / or the PLMN list and / or the OAM configuration information can be achieved in the following ways:
[0047] When the first base station receives the Management Based MDT trigger command (which can also be understood as the activation command) sent by the core network, the Access and Mobility Management Function (AMF) of the core network sends a Management Based MDT PLMN List IE message to the first base station. The first base station obtains the PLMN list and / or OAM configuration information and / or first configuration information from the Management Based MDT PLMN List IE message sent by the AMF.
[0048] S202. Select the UE for MDT data collection.
[0049] In this embodiment of the application, the first base station selects a suitable UE to perform MDT data collection and configures the UE to perform MDT data collection based on the PLMN list in the Management Based MDT PLMN List IE sent from the core network element AMF and the OAM configuration information.
[0050] In this embodiment of the application, determining whether to select the UE may involve determining whether the PLMN of the UE's current location is in the acquired PLMN list or the PLMN list configured by OAM. If it is, then the UE can be selected to perform MDT data collection.
[0051] In this application embodiment, the selection of the UE can be divided into the following two scenarios:
[0052] In the first scenario: OAM can only configure the first base station to check user consent for some MDT measurements within the current PLMN corresponding to the UE's location. In this case, the first base station, based on the PLMN list sent by the core network and the current OAM configuration, can determine the measurements that can be directly collected within the current PLMN. For other measurements, the first base station needs to select the UE based on user consent (i.e., determine whether the PLMN where the current UE is located is in the PLMN list received by the base station). If the OAM configuration does not require user consent for any MDT measurements within the current PLMN, the base station can directly select the UE within the current PLMN.
[0053] The second scenario: OAM can configure the base station to check the user's consent for the MDT measurements in all PLMNs under the same operator. Then, the first base station can know the measurements that can be directly collected in different PLMNs (within a certain area) based on the PLMN list sent by the core network and the current OAM configuration. For other measurements, the first base station needs to select the UE based on the user's consent.
[0054] S203, Send the second configuration information to the UE.
[0055] The second configuration information includes one or more of the following: PLMN list and / or OAM configuration information, measurements that do not require user consent, measurements that require user consent, first configuration information, and an indication identifier, which is used to indicate whether the collected measurements require user consent.
[0056] In this embodiment of the application, after selecting a UE to collect MDT data, the first base station sends second configuration information to the UE for UE configuration. The second configuration information may include one or more of the following:
[0057] (1) The original PLMN list (i.e., the PLMN list issued by the core network) and / or the PLMN list configured by OAM. The PLMN list configured by OAM may include those collected with the user's consent and those collected in the PLMN list issued by the core network that the user does not consent to.
[0058] (2) Indication flag (i.e., indication bit) mainly indicates whether the UE needs the user's consent to measure / collect / report specific measurement quantities when receiving the original PLMN list and the PLMN list in the OAM configuration.
[0059] (3) Measurements that the UE can measure / collect / report (i.e., measurements that do not require user consent).
[0060] (4) Measurements that the UE cannot measure / collect / report (i.e., measurements that require user consent).
[0061] (5) First configuration information.
[0062] It should be noted that the above measurements include, but are not limited to, the Reference Signal Received Power (RSRP) / Reference Signal Received Quality (RSRQ) of the same-frequency / different-frequency serving cell and neighboring cells, UE power margin, uplink and downlink Packet Data Convergence Protocol Service Data Unit (PDCP SDU) data volume measurement, uplink and downlink UE average throughput measurement, uplink and downlink packet delay measurement, uplink and downlink packet loss rate measurement, and Received Signal Strength Indication (RSSI) measurement.
[0063] For example, the first base station can receive a PLMN list sent from the core network and a PLMN list configured by OAM. In the PLMN list sent by the core network and / or the PLMN list configured by OAM, for all measurement quantities, an indication bit (indication identifier) can be used to indicate whether a specific measurement quantity can be directly measured / collected / reported. For example, if a specific measurement quantity can be directly measured / collected / reported, it is set to 1 or true; if a specific measurement quantity cannot be directly measured / collected / reported, it is set to 0 or false.
[0064] In this embodiment of the application, after the UE receives the second configuration information of the first base station, the UE will obtain the corresponding measurement quantities that can be measured, recorded and reported in the corresponding PLMN area, and the corresponding measurement quantities that cannot be measured, recorded and reported, and then perform the measurement / collection / reporting of the corresponding measurement quantities.
[0065] It is understood that in the MDT configuration method provided in this application embodiment, after selecting a UE, the first base station sends second configuration information to the selected UE. Through the second configuration information, the UE can simultaneously obtain the OAM configuration and core network configuration information, determine the latest user consent status corresponding to the measurement quantities to be collected, and perform measurement collection within the corresponding PLMN according to the second configuration information. This avoids erroneous reporting caused by discrepancies between the OAM configuration within the PLMN and the core network configuration information received by the base station, thus improving the accuracy of the reports submitted by the UE during MDT measurements.
[0066] In one embodiment of this application, the first base station may also send a first time to the UE, and the UE records the measurement quantity in the second configuration information within the first time.
[0067] In this embodiment, "first time" can refer to the validity period of the time during which the first base station configures the measurement / collection / reporting of a specific measurement quantity to be performed on the PLMN. That is, it can be understood as the duration within which the first base station's configuration of measuring / collecting / reporting the specific measurement quantity to the UE is valid, or, if the first base station's configuration of not being able to measure / collect / report the specific measurement quantity to the UE is valid, then the UE can measure / collect / report the specific measurement quantity within the validity period.
[0068] It should be noted that the first information can be included in the second configuration information and sent to the UE.
[0069] It should be noted that the validity period of the time can be set for different times for specific measurements, or a uniform time can be set for specific measurements.
[0070] In this embodiment of the application, since the network or network management configuration is not static, the requirements for collecting certain measurement quantities may change frequently. The validity period of the time allows the UE to perceive potential changes in the second configuration information of the first base station configuration, making the feedback of collected data more flexible.
[0071] In one embodiment of this application, the first base station may also receive first information sent by the UE.
[0072] The first information is used to query whether the second configuration information of the first base station has been updated.
[0073] In this embodiment, if the second configuration information includes a first time (i.e., time validity information), the UE can perceive the valid time for performing, recording, and reporting the corresponding measurement quantities within the corresponding PLMN area. When this time expires, the UE can proactively initiate an inquiry process with the first base station when returning to the connected state or the inactive state. The first base station then receives the first information sent by the UE and inquires whether the second configuration information previously configured by the first base station is still valid, for example, whether the allowed measurement quantities configured by the first base station have been updated.
[0074] In one embodiment of this application, the first base station may also send updated second configuration information to the UE; or, send second information to the UE, the second information instructing the UE to continue using the second configuration information or instructing the UE to fail to obtain updated second configuration information.
[0075] In this embodiment of the application, if the second configuration information configured by the first base station is updated, that is, the measurement quantities that the first base station configures for the UE to collect have been updated, the first base station sends the updated second configuration information to the UE to overwrite the original second configuration information.
[0076] It should be noted that for newly added measurement quantities in the updated second configuration information, if the first base station sets a uniform validity period for all measurement quantities, the first base station can uniformly indicate the validity period. If the first base station sets different validity periods for specific measurement quantities, the first base station can indicate different validity periods for the newly added measurement quantities.
[0077] For example, if the first base station sets a uniform valid time for all measurements, the first base station can use an indicator to indicate whether to continue using the previous valid time information or to carry a new valid time information.
[0078] For example, if the first base station sets a uniform valid time for all measurements, and if the updated second configuration information issued by the first base station does not contain time window information (i.e., valid time), the first base station can default to indicating that the previously configured time window information should be used.
[0079] In this embodiment of the application, if the second configuration information configured by the first base station is not updated, the first base station may send a message to the UE to continue using the configured second configuration information or reject the update process initiated by the UE, that is, it may notify the UE that it failed to obtain the updated second configuration information.
[0080] In one embodiment of this application, after the UE moves to the first PLMN outside the PLMN list, it receives a first request sent by the second base station.
[0081] The first request is used to request the second configuration information of the first base station, and the second base station is a base station within the first PLMN.
[0082] In this embodiment of the application, the second base station can also be called the target base station, that is, the base station that the UE moves to in the first PLMN when it moves across PLMNs, at which time the UE is connected to the second base station.
[0083] In this embodiment of the application, when the UE moves across PLMNs, if the UE moves to a PLMN that is not in the PLMN list, when the UE returns to the connected state, it will not send the existing logMeasAvailable IE to the new base station (i.e., the second base station). That is, the UE will not report the indication information to the second base station. When the UE returns to the connected state, it can report a new indication message to the second base station, indicating that the UE has moved to a PLMN that is not in the UE's default configuration list, i.e., a PLMN that the user has not agreed to collect.
[0084] At this time, if the second base station does not obtain the OAM configuration update information, the first base station will receive the first request sent by the second base station, requesting to obtain the second configuration information of the first base station. This can be understood as follows: if the local OAM configuration is not updated and the UE does not receive the OAM configuration update information, the first base station will receive the first request sent by the second base station.
[0085] Specifically, if the local OAM configuration has not been updated, and the validity period of the configuration provided by the first base station (i.e., the original base station) for the UE has expired, the UE can send a request message to the second base station (i.e., the target base station) when it returns to the connected state, requesting the latest configuration information from the original base station.
[0086] If the second base station does not know the second configuration information of the first base station, the second base station can send a UE context acquisition message or other request message to the first base station through the Xn interface to request the second configuration information of the first base station, such as the PLMN list.
[0087] In this embodiment of the application, the first base station receives a first request sent by the second base station and responds to the first request by sending second configuration information to the second base station so that the second base station can reselect the UE to perform MDT data collection and send the second configuration information to the UE.
[0088] In this embodiment of the application, the first base station sends second configuration information to the second base station. The second base station can reselect the UE for MDT data collection based on the obtained second configuration information, and send configuration information to the reselected UE for configuration.
[0089] Specifically, if the second configuration information of the first base station has been updated, the first base station forwards the updated second configuration information, including the updated PLMN list, to the second base station. At this time, the second base station can select the UE based on the updated second configuration information (such as the updated PLMN list).
[0090] If the updated PLMN list contains the PLMN where the current UE is located, the second base station sends the updated second configuration information to the UE; if the updated PLMN list does not contain the PLMN where the current UE is located, the second base station will reject the UE's request and will not select the UE for MDT measurement and data collection.
[0091] If the second configuration information of the first base station is not updated, the first base station may not send the updated second configuration information (such as the updated PLMN list) to the second base station. The second base station instructs the UE to continue using the previous validity period and the previous second configuration information.
[0092] This application also provides an MDT configuration method, such as... Figure 3 As shown, when applied to a UE, the method may include:
[0093] S301, Receive the second configuration information sent by the first base station.
[0094] The second configuration information includes one or more of the following: PLMN list and / or OAM configuration information, measurements that do not require user consent, measurements that require user consent, first configuration information, and an indication identifier, which is used to indicate whether the collected measurements require user consent.
[0095] S302. After receiving the second configuration information, measure the quantity to be measured.
[0096] In this embodiment, after receiving the second configuration information, the UE can determine the measurable quantities based on the second configuration information, that is, the corresponding measurable quantities that can be measured, recorded, and reported within the corresponding PLMN area, and the corresponding measurable quantities that cannot be measured, recorded, and reported. Then, the corresponding measurement / collection / reporting is performed, thereby completing the measurement for the determined measurable quantities.
[0097] It is understood that in the MDT configuration method provided in this application embodiment, after selecting a UE, the first base station sends second configuration information to the selected UE. Through the second configuration information, the UE can simultaneously obtain the OAM configuration and core network configuration information, determine the latest user consent status corresponding to the measurement quantities to be collected, and perform measurement collection within the corresponding PLMN according to the second configuration information. This avoids erroneous reporting caused by discrepancies between the OAM configuration within the PLMN and the core network configuration information received by the base station, thus improving the accuracy of the reports submitted by the UE during MDT measurements.
[0098] In one embodiment of this application, the UE may also receive a first time transmitted by the first base station; and within the first time, record the measurement quantity in the second configuration information.
[0099] In this embodiment of the application, the first time can be included in the second configuration information and sent to the UE together with the first base station.
[0100] In this embodiment of the application, the first time can refer to the validity period of the time during which the first base station configures the UE to measure / collect / report a specific measurement quantity in the PLMN.
[0101] In this embodiment of the application, the first base station configures the validity period of the measurement / collection / reporting of a specific measurement quantity in the PLMN. The UE can perceive the validity period of the measurement / collection / reporting of the corresponding measurement quantity in the corresponding PLMN area, and the UE performs MDT measurement within the validity period of the measurement quantity.
[0102] It should be noted that the validity period for each measurement can be the same or different.
[0103] In one embodiment of this application, after the first timeout, a first message is sent to the first base station. The first message is used to inquire whether the second configuration information of the first base station has been updated.
[0104] In this embodiment of the application, after the time validity period expires, the UE can actively initiate an inquiry process to the first base station when returning to the connected state or the inactive state, that is, send the first information to the first base station to inquire whether the second configuration information previously configured by the first base station is still valid (or whether it has been updated), that is, whether the measurement quantities allowed to be collected in the second configuration information have been updated.
[0105] In one embodiment of this application, the UE receives updated second configuration information sent by the first base station and records the measurement quantities in the second configuration information; or, the UE receives second information sent by the first base station, the second information instructing the UE to continue using the second configuration information or instructing the UE to fail to obtain updated second configuration information.
[0106] In this embodiment of the application, if the measurement quantities that the first base station configures for the UE to collect are updated, that is, the second configuration information is updated, the first base station will send the updated second configuration information to the UE. After receiving the updated second configuration information, the UE will overwrite the original second configuration information and measure / record / report the measurement quantities in the updated second configuration information.
[0107] In this embodiment of the application, if the second configuration information configured by the first base station for the UE is not updated, the UE receives the second information sent by the first base station. The second information instructs the UE to continue using the second configuration information configured by the first base station, or the second information instructs the UE to fail to obtain the updated second configuration information, that is, the first base station rejects the update process initiated by the UE.
[0108] In one embodiment of this application, after the UE moves to the first PLMN outside the PLMN list and the first time expires, it sends third information to the second base station. The third information instructs the UE to move to the first PLMN. The second base station is a base station within the first PLMN.
[0109] In this embodiment of the application, when the UE moves across PLMNs, if the UE moves to a first PLMN that is not in the PLMN list, and the first timeout occurs, the UE will not send the existing logMeasAvailable IE to the second base station when it returns to the connected state. That is, the UE will not report the indication to the second base station. When the UE returns to the connected state, it reports new indication information (i.e., third information) to the second base station. Through the third information, the UE is instructed to move to a PLMN that is not in the UE's default configured PLMN list, i.e., a PLMN that the user has not agreed to collect (i.e., the first PLMN).
[0110] In one embodiment of this application, the UE receives updated second configuration information sent by a second base station. The updated second configuration information includes one or more of the following: an updated PLMN list and / or updated OAM configuration information, updated measurements requiring user consent, updated measurements not requiring user consent, and updated indication identifiers; or, the UE receives fourth information sent by the second base station, the fourth information being used to indicate that the UE failed to obtain the updated second configuration information, and / or the fourth information being used to indicate that the UE continues to use the second configuration information.
[0111] In this embodiment, if the local OAM configuration has been updated—that is, some measurements that previously required user consent checks no longer need to check user consent, or some measurements that previously did not require user consent checks do—the second base station can resend the updated second configuration information to the UE. The UE receives the updated second configuration information resent by the second base station. This configuration information may include an updated PLMN list and / or updated OAM configuration information, updated user consent information for measurements (i.e., measurements requiring user consent and measurements not requiring user consent), and updated indication identifiers.
[0112] In this embodiment of the application, the updated second configuration information may also include updated time window information (i.e., time validity period).
[0113] In this embodiment of the application, if the updated PLMN list does not contain the first PLMN where the current UE is located, the second base station will send a fourth message to the UE, indicating that the UE failed to obtain the updated second configuration information, that is, the UE will not be selected for MDT measurement collection.
[0114] In this embodiment of the application, the UE may also receive fourth information sent by the second base station, which instructs the UE to continue using the second configuration information.
[0115] In this embodiment of the application, if the second configuration information of the first base station is not updated, the first base station may not forward the updated second configuration information (including the PLMN list) to the second base station. The target base station sends fourth information to the UE, instructing the UE to continue using the original configured second configuration information.
[0116] It should be noted that the second configuration information may include a time validity period (i.e., the first time).
[0117] In one embodiment of this application, a second request instruction is sent to the second base station to obtain updated second configuration information of the first base station, and the second request instruction includes the first PLMN corresponding to the second base station.
[0118] In this embodiment of the application, if the local OAM configuration has not been updated and the validity period of the configuration set by the first base station for the UE has expired, the UE can send a second request indication to the second base station when it returns to the connected state, requesting the latest configuration from the first base station.
[0119] In this embodiment of the application, if the second base station did not previously know the second configuration information of the first base station, the second base station can request the second configuration information of the first base station by initiating a UE context acquisition message or other messages to the first base station through the Xn interface.
[0120] If the second configuration information of the first base station has been updated, the first base station sends the updated second configuration information (including the updated PLMN list) to the second base station, and the second base station can select the UE according to the updated PLMN list.
[0121] If the updated PLMN list contains the first PLMN where the current UE is located, the second base station sends the updated second configuration information to the UE.
[0122] Based on the above embodiments, this application has the following technical advantages:
[0123] By configuring the UE on the base station side, the UE can obtain the latest user consent information in advance, and the UE can perform measurement reporting within the corresponding PLMN. This solves the scenario where incorrect reporting occurs due to discrepancies between the network management configuration within the PLMN and the configuration received from the core network at the base station.
[0124] Based on the above embodiments, another embodiment of this application provides a first base station 1, such as... Figure 4 As shown, the first base station 1 includes:

The second configuration information includes one or more of the following: PLMN list and / or OAM configuration information, measurement quantities that do not require user consent, measurement quantities that require user consent, first configuration information, and indication identifier. The indication identifier is used to indicate whether the collected measurement quantities require user consent.
[0128] In one embodiment, the sending unit 12 is further configured to send a first time to the UE, and the UE records the measurement quantity in the second configuration information within the first time.

[0133] In one embodiment, the receiving unit is further configured to receive a first request sent by a second base station after the UE moves to a first PLMN outside the PLMN list. The first request is used to request second configuration information of the first base station, and the second base station is a base station within the first PLMN.
[0134] In one embodiment, the receiving unit is further configured to receive a first request sent by the second base station if the second base station has not obtained OAM configuration update information.
[0135] In one embodiment, the sending unit 12 is further configured to send second configuration information to the second base station so that the second base station can reselect the UE to perform MDT data collection and send the second configuration information to the UE.
[0136] This application provides a first base station that acquires first configuration information and / or a PLMN list and / or OAM configuration information; selects a UE to collect MDT data; and sends second configuration information to the UE. The second configuration information includes one or more of the following: a PLMN list and / or OAM configuration information, measurement quantities that do not require user consent, measurement quantities that require user consent, the first configuration information, and an indication flag. The indication flag indicates whether the collected measurement quantities require user consent. Therefore, this application proposes a first base station that, after selecting a UE, sends second configuration information to the selected UE. Through the second configuration information, the UE can simultaneously obtain the OAM configuration and core network configuration information, determine the latest user consent status corresponding to the measurement quantities to be collected, and perform measurement collection within the corresponding PLMN according to the second configuration information. This avoids erroneous reporting caused by discrepancies between the OAM configuration within the PLMN and the core network configuration information received by the base station, improving the accuracy of the reports submitted by the UE during MDT measurements.
