It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0036] The steps illustrated in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in a different order than that presented here.

[0037] In one exemplary implementation Figure 1 This is a flowchart illustrating a measurement method provided in an embodiment of this application. This method is applicable to continuous multi-step measurement (MDT). The method can be executed by the measurement device provided in this application, which can be implemented in software and / or hardware and is generally integrated on a first communication node. The first communication node can be a user interface device (UE).

[0038] like Figure 1 As shown, the measurement method provided in this application includes the following steps:

[0039] S110. Obtain minimized roadside MDT measurement configuration information, wherein the MDT measurement configuration information instructs the first communication node to perform continuous MDT measurement.

[0040] MDT measurement configuration information can instruct the first communication node to perform continuous MDT measurements. The MDT measurement configuration information can instruct the first communication node to perform continuous MDT measurements in idle, inactive, or connected states.

[0041] MDT measurement configuration information can be transmitted from the second communication node to the first communication node to instruct the first communication node to perform continuous MDT measurements. The content of the MDT measurement configuration information is not limited, as long as it can instruct the first communication node to perform continuous MDT measurements. For example, the MDT measurement configuration information may include indication information or MDT measurement activation information to indicate the state in which the first communication node performs continuous MDT measurements; the MDT measurement configuration information may also include MDT location prediction measurement configuration information, which can indicate the content to be measured.

[0042] S120. Generate and transmit a measurement report based on the MDT measurement configuration information.

[0043] The measurement report can be a report generated based on data collected after continuous MDT measurements. After obtaining the MDT measurement configuration information, this step can perform MDT measurement collection based on the MDT measurement configuration information and store the collected data. The collected data can be used to generate the measurement report. The content included in the measurement report can be determined based on the content included in the MDT location prediction measurement configuration information.

[0044] The timing of generating and transmitting the measurement report is not limited here. It can be generated and sent when the second communication node requests the first communication node to send the measurement report; or the measurement report can be generated in advance and sent to the second communication node when the second communication node requests the first communication node to send the measurement report; or the measurement report can be generated at a set time and sent directly to the second communication node. The set time is not limited and can be determined according to the actual situation.

[0045] This example provides a measurement method that enables continuous MDT measurements based on MDT measurement configuration information, thereby generating and transmitting measurement reports to facilitate network optimization.

[0046] Based on the above embodiments, modified embodiments of the above embodiments are proposed. It should be noted that, in order to keep the description brief, only the differences from the above embodiments are described in the modified embodiments.

[0047] In one embodiment, the MDT measurement configuration information is one of an RRC message and recorded MDT measurement activation information; wherein the RRC message is an RRC establishment request message, an RRC reconfiguration message, or a location prediction request message.

[0048] The location prediction request information can be used to instruct the first communication node to perform continuous MDT measurements.

[0049] In one embodiment, the measurement report includes measurements of one or more of the following states: idle state; inactive state; connected state.

[0050] The content included in the measurement report can be determined based on the information indicated by the MDT measurement configuration information. For example, when the MDT measurement configuration information indicates that the first communication node performs continuous MDT measurements in an idle state, the measurement report may include measurements taken in the idle state. When the MDT measurement configuration information indicates that the first communication node performs continuous MDT measurements in an inactive state, the measurement report may include measurements taken in the inactive state. When the MDT measurement configuration information indicates that the first communication node performs continuous MDT measurements in a connected state, the measurement report may include measurements taken in the connected state.

[0051] In one embodiment, the measurement report includes continuous historical location measurement information of the first communication node in continuous state, and the continuous historical location measurement information includes one or more of the following: latitude and longitude coordinates of one or more time points; connection cell identifiers of one or more time points; movement direction angle of the first communication node at one or more time points; and movement speed of the first communication node at one or more time points.

[0052] Continuous states can include one or more of the following: idle state; inactive state; connected state. Continuous historical location measurement information is information obtained by the first communication node during continuous MDT measurements, and this information can be used for location prediction.

[0053] The direction angle of motion can be understood as the angle that represents the direction of motion.

[0054] In one embodiment, the MDT measurement configuration information includes one or more of the following: MDT measurement activation information; MDT continuous measurement reporting indication information; indication information for whether to record MDT measurements in the connected state; indication information for whether to record MDT measurements in the inactive state; indication information for whether to record MDT measurements residing in the idle state; and MDT location prediction measurement configuration information.

[0055] MDT measurement activation information indicates the state in which the first communication node performs MDT measurements. MDT continuous measurement reporting indication information instructs the first communication node to continuously report measurements. MDT location prediction measurement configuration information indicates the content that the first communication node needs to measure during continuous MDT measurements.

[0056] The MDT continuous measurement reporting indication information can be considered as indication information for whether to perform continuous MDT measurement reporting. The indication information for whether to record connected-state MDT measurements indicates whether to record connected-state MDT measurements. The indication information for whether to record inactive-state MDT measurements indicates whether to record inactive-state MDT measurements. The indication information for whether to record idle-state residing MDT measurements indicates whether to record idle-state residing MDT measurements.

[0057] In one embodiment, when the MDT measurement configuration information includes MDT location prediction measurement configuration information, the MDT measurement activation information indicates the following: the MDT continuous measurement reporting indication is set to affirmative; whether to record connected MDT measurements is set to affirmative; whether to record inactive connected MDT measurements is set to affirmative; and whether to record idle MDT measurements is set to affirmative.

[0058] When the MDT measurement configuration information includes MDT location prediction configuration information, the first communication node can perform continuous MDT measurements in connected, idle and inactive states by setting the MDT continuous measurement reporting indication to affirmative, setting whether to record MDT measurements in the connected state to affirmative, setting whether to record MDT measurements in the inactive state to affirmative, and setting whether to record MDT measurements in the idle state to affirmative.

[0060] The location measurement cycle can be considered as the period during which location measurements are performed. The effective time for location prediction measurement configuration can be understood as the effective time for performing location prediction measurement configuration.

[0061] In one exemplary embodiment, this application also provides a measurement method. Figure 2 This is a flowchart illustrating a measurement method provided in an embodiment of this application. This method is applicable to continuous multi-dimensional distance measurement (MDT) and can be executed by the measurement device provided in this application, integrated into a second communication node. The second communication node includes, but is not limited to, a base station.

[0062] like Figure 2 As shown, the measurement method provided in this application includes the following steps:

[0063] S210. Transmit MDT measurement configuration information, wherein the MDT measurement configuration information instructs the first communication node to perform continuous MDT measurement.

[0064] The second communication node can first determine the MDT measurement configuration information, and then transmit it. The content of the MDT measurement configuration information is not limited and can be determined based on the required measurement content and status. The MDT measurement configuration information can instruct the first communication node to perform continuous MDT measurements, thereby obtaining the measurement report transmitted by the first communication node for network optimization.

[0065] S220. Obtain the measurement report transmitted by the first communication node, the measurement report being used for network optimization.

[0066] After transmitting the MDT measurement configuration information to the first communication node, this step can obtain the measurement report transmitted by the first communication node to perform network optimization based on the measurement report. The specific method of network optimization based on the measurement report is not limited here.

[0067] For details not covered in this example, please refer to the above embodiments, which will not be repeated here.

[0068] The measurement method provided in this example can control the first communication node to perform continuous MDT measurements by sending MDT measurement configuration information to the first communication node, thereby obtaining the measurement report fed back by the first communication node and thus achieving network optimization.

[0069] Based on the above embodiments, modified embodiments of the above embodiments are proposed. It should be noted that, in order to keep the description brief, only the differences from the above embodiments are described in the modified embodiments.

[0070] In one embodiment, the MDT measurement configuration information is one of an RRC message and recorded MDT measurement activation information; wherein the RRC message is an RRC establishment request message, an RRC reconfiguration message, or a location prediction request message; the MDT measurement configuration information is transmitted after obtaining the indication information of the MDT predicted location measurement.

[0071] In one embodiment, the measurement report includes measurements of one or more of the following states: idle state; inactive state; connected state.

[0072] In one embodiment, the measurement report includes continuous historical location measurement information of the first communication node in continuous state, and the continuous historical location measurement information includes one or more of the following: latitude and longitude coordinates of one or more time points; connection cell identifiers of one or more time points; movement direction angle of the first communication node at one or more time points; and movement speed of the first communication node at one or more time points.

[0073] In one embodiment, the MDT measurement configuration information includes one or more of the following: MDT measurement activation information; MDT continuous measurement reporting indication information; indication information for whether to record MDT measurements in the connected state; indication information for whether to record MDT measurements in the inactive state; indication information for whether to record MDT measurements residing in the idle state; and MDT location prediction measurement configuration information.

[0074] In one embodiment, when the MDT measurement configuration information includes MDT location prediction measurement configuration information, the MDT measurement activation information indicates the following: the MDT continuous measurement reporting indication is set to affirmative; whether to record connected MDT measurements is set to affirmative; whether to record inactive connected MDT measurements is set to affirmative; and whether to record idle MDT measurements is set to affirmative.

[0075] In one embodiment, the MDT location prediction measurement configuration information includes one or more of the following: location measurement period; location prediction measurement configuration validity period; indication information on whether latitude and longitude coordinate measurement is required; indication information on whether altitude measurement is required; indication information on whether measurement and recording of the connected cell identifier is required; indication information on whether speed measurement is required; and indication information on whether the motion direction angle measurement of the first communication node is required.

[0076] In one embodiment, the method further includes:

[0077] Transmit the measurement report;

[0078] Obtain predicted location information, which is generated based on the measurement report, and use the predicted location information for network optimization.

[0079] After obtaining the measurement report, the second communication node can send the report to the device performing the predicted location information determination, such as the core network or location service network element, so that the device can determine the predicted location information. The predicted location information can be understood as the predicted location information, which can be generated based on the measurement report; the specific generation method is not limited here. After obtaining the predicted location information, the second communication node can use it for network optimization.

[0080] The following is an exemplary description of this application. The measurement method provided in this application can be considered a continuous measurement method. Existing MDT technologies do not support continuous measurement and collection by the UE in idle, inactive, and connected states. Furthermore, existing Logged MDT measurements are only taken in the idle state and reported upon entering the connected state. However, some functions on the wireless network side cannot rely solely on measurements taken in the idle state. For example, the network-side location prediction function requires the collection of historical location measurement data and related measurement data. The network-side Artificial Intelligence (AI) function requires a continuous historical data of the UE user's trajectory for training and prediction. This means that the UE needs to perform location-related measurements in idle, inactive, and connected states and subsequently notify the network. Therefore, it is necessary to solve how to perform continuous MDT measurement and collection in multiple UE states.

[0081] Existing Radio Access Networks (RANs) only support current terminal location positioning and cannot predict the terminal's possible location at the next time point based on relevant historical training data. Predicting terminal location is crucial for improving handover success rates between base stations and for load balancing. Currently, UEs only perform location measurements in idle mode, so the network cannot obtain continuous historical location data of the UE's user trajectory from the UE's measurement reports, thus hindering prediction. Therefore, it is necessary to address how to perform continuous location measurement and location-related measurements (MDT) across multiple UE states.

[0082] MDT (Mean Transmission Testing) is an automated drive test technology introduced by the 3rd Generation Partnership Project (3GPP) in LTE systems. It involves collecting and reporting measurement data from ordinary users / commercial terminals through network configuration. This application provides a novel method that enables continuous MDT measurement collection by the UE in idle, inactive, and connected states. It utilizes historical measurement data of the continuously collected UE user trajectories for training and prediction, and incorporates UE velocity and motion direction angle measurements to improve the accuracy of UE location prediction. In this application, the UE can continuously report measurement data, i.e., measurement reports, thereby improving the accuracy of UE location prediction.

[0083] Figure 2a This is a schematic diagram of a process for determining predicted location information provided in an embodiment of this application. See also... Figure 2a This example illustrates location prediction based on continuous measurements from a recorded MDT. The steps involved in determining the predicted location information are as follows:

[0084] 1. The base station receives UE-related messages sent by the core network, such as UE text establishment request (i.e., initial context setup request) messages, handover request messages, or path request messages (i.e., Trace start), which carry an indication to activate the UE's MDT predicted location measurement.

[0085] 2. The base station sends MDT measurement activation information to the UE via the air interface. This information includes one or more of the following: MDT continuous measurement reporting indication; indication of whether to record MDT measurements in the connected state (RRC_CONNECTED); indication of whether to record MDT measurements in the INACTIVE state; indication of whether to record MDT measurements in the idle state (RRC_IDLE); and MDT location prediction measurement configuration information, which instructs the UE to perform relevant measurements.

[0086] The MDT location prediction measurement configuration information includes one or more of the following: location measurement period; location prediction measurement configuration validity period; indication information on whether latitude and longitude coordinate measurement is required; indication information on whether altitude measurement is required; indication information on whether the connected or camped cell identifier is required to be measured and recorded; indication information on whether velocity measurement is required; and indication information on whether UE orientation angle measurement is required.

[0087] When MDT location prediction measurement configuration information is configured, the MDT measurement activation information indicates the following items: MDT continuous measurement reporting indication is set to affirmative; whether to record MDT measurements in the connected state (RRC_CONNECTED) is set to affirmative; whether to record MDT measurements in the INACTIVE state is set to affirmative; and whether to record MDT measurements in the idle state (RRC_IDLE) is set to affirmative.

[0088] 3. The UE receives the MDT measurement activation information and performs the corresponding measurements in the idle state, the inactive state, or the connected state, according to the content therein.

[0089] 4. The base station sends a message request (i.e., UE Information Request) to the UE via the air interface, indicating the MDT measurements that the UE needs to report.

[0090] 5. The UE sends a UE message response (i.e., UE Information Response) to the base station, which includes one or more of the following continuous historical location measurement information of the UE in continuous state: latitude and longitude coordinates of one or more time points; connected cell identifiers of one or more time points; UE movement direction angles of one or more time points; and UE movement speeds of one or more time points.

[0091] 6. The base station sends the received UE measurement report to the location service network element.

[0092] 7. The location service network element calculates the UE's current location and predicted location or predicted cell at a future point in time or a future time period based on the continuous historical location measurement information of the UE in continuous state.

[0093] 8. The location service network element sends the predicted location information to the base station. The predicted location information includes the predicted location of one or more UEs at a future point in time or time period, and may be one or more of the following: predicted latitude and longitude coordinates; predicted cell identifier; predicted altitude information; predicted connection beam identifier information with a certain cell; and predicted tracking area (TA) information.

[0094] 9. The base station receives predicted location information or predicted cell location sent by the location service network element, and uses the UE's predicted location or predicted cell location for network optimization.

[0095] It should be noted that the predicted location information can also be determined by the core network.

[0096] Figure 2b For another flowchart illustrating the determination of predicted location information provided in this application, see [link to relevant documentation]. Figure 2b This example illustrates location prediction based on location prediction MDT measurement configuration. When determining predicted location information, the base station sends MDT measurement configuration information, such as an RRC message, to the UE via the air interface, instructing the relevant UE to perform related measurements. The RRC message can be an RRC establishment request message, an RRC reconfiguration message, or a new message, such as a location-prediction request message.
