[0002] Minimization of Drive-tests (MDT) is an automatic drive test technology introduced by the 3rd Generation Partnership Project (3GPP) in the Long Term Evolution (LTE) system, which is configured by the network to collect and report measurement data of ordinary users or commercial terminals. The principle is that as long as the user terminal starts the Global Positioning System (GPS) and supports the MDT function, the terminal can automatically report the MDT data containing the user position information to the base station.

It should be explained that the embodiments in the present application and the features in the embodiments can be any combination without conflict.

Also, the "first", "second", "third" in the embodiments of the present application are only used to distinguish different concepts, messages, etc., and are not used for the sequential limitation.
[0040] Figure 1 A flow chart of a position prediction method provided by the embodiments of the present application, which can be applied to a location service network element, such as a location server, as shown in the figure. The method specifically comprises the following steps. Figure 1
[0041] S101, the location service network element receives the MDT measurement information message sent by the base station.
[0042] In the embodiments of the present application, the location service network element can be a separate network element independent of the base station, or a network element located in the base station.
[0043] Correspondingly, when the location service network element is a separate network element, the implementation mode of the above step S101 can be that the location service network element receives the MDT measurement information message sent by the base station through the interface between the location service network element and the base station. When the location service network element is a network element located in the base station, the implementation mode of the above step S101 can be that the location service network element receives the MDT measurement information message sent by the base station through the interface in the base station.
[0044] The above MDT measurement information message carries the historical position measurement information of at least one UE, wherein the historical position measurement information can include at least one of the following information:
[0045] the latitude and longitude coordinates at one or more time points, the connection cell identifier at one or more time points, the pilot fingerprint measurement value at one or more time points, the wireless local area network identifier recorded at one or more time points, the positioning reference signal time difference of multiple cells at one or more time points, and the connection beam identifier of the connection cell at one or more time points.
[0046] S102, the location service network element determines the predicted location information of the at least one UE at the first time point or the first time period according to the historical location measurement information of the at least one UE.
[0047] In this step, the first time point or the first time period can be a future time point or a future time period, that is, the above step can be understood as that after the location service network element obtains the historical location measurement information of the at least one UE in the MDT measurement information message based on step S101, the location service network element determines the predicted location information of the at least one UE at a future time point or a future time period according to the historical location measurement information of the at least one UE.
[0048] Optionally, the above implementation manner can be that the location service network element determines the predicted location information of the at least one UE at the first time point or the first time period according to the historical location measurement information of the at least one UE and the current location of the at least one UE.
[0049] Exemplarily, the predicted location information can include at least one of the longitude and latitude coordinates, the cell identifier, the altitude information, the connection beam identifier of the connected cell, and the tracking area information.
[0050] S103, the location service network element sends the predicted location information to the base station.
[0051] Since the location service network element can be a separate network element or a network element located in the base station, the above implementation manner can have the following different optional implementation manners:
[0052] When the location service network element is a separate network element, the location service network element sends the predicted location information to the base station through the interface between the location service network element and the base station;
[0053] When the location service network element is a network element located in the base station, the location service network element sends the predicted location information to the control plane of the base station through the interface in the base station.
[0054] In the above manner, the location service network element can predict the predicted location information of the corresponding UE at a specific time point or time period (for example, the first time point or the first time period) based on the related historical location data of the at least one UE.
[0055] Figure 2 A flowchart of a location prediction method provided by an embodiment of the present application, which can be applied to a base station, as shown in Figure 2 The method specifically includes the following steps.
[0056] S201, the base station sends MDT measurement activation information to the determined at least one UE.
[0057] In the embodiments of the present application, the base station can send the MDT measurement activation information to the determined at least one UE through the air interface, where the MDT measurement activation information is used to instruct the determined at least one UE to perform the location measurement.
[0058] Optionally, when the base station sends the MDT measurement activation information to the determined at least one UE through the air interface, the base station can carry the MDT measurement activation information in a radio resource control (RRC) setup message or an RRC reconfiguration message, that is, the base station sends the MDT measurement activation information to the determined at least one UE by sending the RRC setup message or the RRC reconfiguration message.
[0059] Optionally, the MDT measurement activation information is used to instruct the determined at least one UE to perform the related measurement, and the MDT measurement activation information can further carry the MDT location prediction measurement configuration information.
[0060] For example, the MDT location prediction measurement configuration information can include at least one of the following information:
[0061] The location measurement period, the location prediction measurement configuration validity time, whether to measure the latitude and longitude coordinates, whether to measure and record the connected cell identifier, whether to measure the pilot fingerprint (for example, the measurement value of the specified pilot channel strength of the current connected cell and several adjacent cells), whether to measure and record the wireless local area network identifier, whether to measure the positioning reference signal time difference, the positioning reference signal measurement assistance data (for example, the physical cell identifier (PCI), the cell identifier, the frequency point, the positioning reference signal configuration and other information of the connected cell and the adjacent cell), and whether to measure and record the connected beam of the connected cell.
[0062] S202, the base station receives the MDT measurement report sent by the at least one UE according to the MDT measurement activation information.
[0063] After the determined at least one UE in step S201 receives the MDT measurement activation information sent by the base station, the at least one UE can perform the corresponding measurement according to the content in the MDT measurement activation information, and report the measurement result in the form of the MDT measurement report in response to the measurement reporting request of the base station, periodically or eventually.
[0064] Correspondingly, the base station receives the MDT measurement report sent by the at least one UE according to the MDT measurement activation information, where the MDT measurement report contains the historical location measurement information of the at least one UE.
[0065] Optionally, the historical location measurement information of the at least one UE can include at least one of the following information:
[0066] longitude coordinates of one or more time points, connection cell identities of one or more time points, pilot fingerprint measurement values of one or more time points, wireless local area network identities recorded at one or more time points, positioning reference signal time difference of arrival of a plurality of cells at one or more time points, connection beam identities of connection cells at one or more time points.
[0067] S203, the base station sends the historical location measurement information of the at least one UE to a location service network element through an MDT measurement information message.
[0068] After the base station acquires the historical location measurement information in the MDT measurement report sent by the at least one UE, the base station can send the historical location measurement information of the at least one UE to the location service network element through an MDT measurement information message.
[0069] Optionally, the location service network element can be a separate network element independent of the base station, or a network element located inside the base station. Accordingly, the implementation mode of the above step S203 can be divided into the following two cases:
[0070] When the location service network element is a separate network element, the base station sends the MDT measurement information message to the location service network element through an interface between the base station and the location service network element;
[0071] Or, when the location service network element is a network element located inside the base station, the base station sends the MDT measurement information message to the location service network element through an interface inside the base station.
[0072] S204, the base station receives the predicted location information of the at least one UE at a first time point or a first time period sent by the location service network element according to the historical location measurement information.
[0073] After the base station sends the MDT measurement information message to the location service network element through step S203, the location service network element can determine the predicted location information of the at least one UE at a first time point or a first time period according to the historical location measurement information of the at least one UE acquired through the MDT measurement information message, and then send it to the base station.
[0074] The predicted location information of the at least one UE at a first time point or a first time period received by the base station can be the predicted location information of the at least one UE at a future time point or a future time period.
[0075] Exemplarily, the above predicted location information can include at least one of the following information:
[0076] The latitude and longitude coordinates, the cell identifier, the altitude information, the connection beam identifier of the connected cell, and the tracking area information, wherein one tracking area can be composed of one cell or multiple cells.
[0077] After the base station receives the predicted location information sent by the location service network element, the base station can perform connection management on the corresponding UE according to the predicted location information, so as to balance the network load. For example, the base station can select a target cell for handover or balancing for a certain UE according to the predicted location information of the UE.
[0078] Further, in the embodiments of the present application, since the at least one UE is determined by the base station, in an example, the base station determines the at least one UE in the following manner: the base station receives a first message sent by the core network, the first message carrying an indication of whether the at least one UE supports MDT predicted location measurement, and the base station receives a second message sent by an operation administration and maintenance (OAM) node, the second message carrying effective area information of the predicted location, and then the base station determines the at least one UE supporting the MDT predicted location in the effective area according to the obtained effective area information.
[0079] For example, the first message can be a UE text establishment request (initial context setup request) message or a handover request message initiated by a core access and mobility management function (AMF) node through an NG interface, and the second message can be an MDT activation message sent by the OAM node through an interface connected to the base station, which can be used to instruct the base station to start the MDT function.
[0080] It should be noted that, in the embodiments of the present application, the order in which the core network sends the first message and the OAM node sends the second message is not limited.
[0081] In an example, the base station determines the at least one UE in the following manner: the base station receives a third message sent by the core network, the third message carrying an indication of activating MDT predicted location measurement of the corresponding UE, and the base station determines the at least one UE according to the third message.
[0082] Exemplarily, the third message can be a UE initial context setup request message, or a handover request message, or a trace start message, or a trace activation message initiated by the core network AMF node through the NG interface.
[0083] It should be noted that the third message carrying the indication of activating the corresponding UE MDT predicted location measurement can be understood as different third messages carrying the indication of activating different UE MDT predicted location measurements. For example, the base station receives three third messages sent by the core network, and the three third messages respectively carry the indications of activating the MDT predicted location measurements of UE1, UE2 and UE3. Then, the base station can determine at least one UE, i.e., UE1, UE2 and UE3, based on the received third messages.
