The present application does not limit the terminal equipment in the PLMN network.

[0116] By way of example and not limitation, in this application, a terminal device may be a terminal device in an Internet of Things (IoT) system. The IoT is an important component of the future development of information technology. Its primary technical feature is connecting objects to the Internet through communication technologies, thereby realizing an intelligent network that interconnects humans and machines, and objects and things. For example, the terminal device in the embodiments of this application may be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for wearable devices that utilize wearable technology to intelligently design and develop wearable devices, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that can be worn directly on the body or integrated into a user's clothing or accessories. Wearable devices are not just hardware devices; they can also achieve powerful functionality through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include devices that are fully functional, large in size, and can achieve full or partial functionality independently of a smartphone, such as smart watches or smart glasses, as well as devices that focus on a specific application function and require integration with other devices, such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0117] As an example and not a limitation, in an embodiment of the present application, the terminal device may also be a terminal device in a machine type communication (MTC).

[0118] For communication quality optimization scenarios, communication quality optimization can be achieved through Minimization Drive Test (MDT) technology. Minimization Drive Test technology is an automated drive test technology that configures terminal equipment through network equipment to collect, report, and pre-process measurement data. When the terminal device turns on GPS and supports the Minimization Drive Test function, the technology can automatically report Minimization Drive Test data containing user location information to the terminal device. Minimization Drive Test data contains fields such as RSRP and RSRQ, and contains GPS latitude and longitude information, which can be used for communication quality analysis. The design concept of Minimization Drive Test technology includes minimizing the additional consumption of terminal equipment and maximizing the availability of location information, aiming to reduce the labor, equipment, and time costs required for traditional drive testing and improve drive testing efficiency. Minimization Drive Test technology can be applied to areas that test vehicles cannot reach, such as narrow roads and residential areas, and can report problems with ordinary terminal equipment in a timely manner.

[0119] In related technologies, a network device performs cell switching based on a measurement report reported by a terminal device and a pre-configured switching condition, and triggers cell switching when the measurement report meets the switching condition.

[0120] As an example and not a limitation, switching conditions include conditional LTM execution and conditional LTM recovery. Conditional LTM execution means that when certain conditions are met, the network device performs long-term data transmission optimization on the terminal device according to the preset configuration. These conditions include but are not limited to network load, device performance, and user behavior. When these conditions are met, the network device may automatically adjust the configuration to optimize performance. Conditional LTM recovery means that the network device will return to the previous configuration state when the previous configuration fails or is no longer applicable for some reason. This usually occurs in situations such as network failure, device failure, or changes in user behavior. In these cases, the network device may fall back to the previous configuration to maintain service continuity and stability.

[0121] For mobile terminal devices, continuous switching may be required to optimize the communication quality of the terminal devices. During the continuous switching process, the triggering of the above-mentioned switching conditions may occur. Triggering different switching conditions will result in different target cells for switching. Different target cells correspond to different communication qualities. The problem that the communication quality of the target cell for switching is not the optimal communication quality may occur.

[0122] Figure 2 is a schematic diagram of the triggering handover conditions provided in an embodiment of the present application. As shown in Figure 2, a terminal device sends a measurement report to a network device, and the network device performs a handover based on the measurement report and preconfigured handover conditions. The handover execution includes triggering the LTM execution condition to switch to cell 1 or triggering the LTM recovery condition to switch to cell 2. The communication quality of cell 1 and cell 2 is different.

[0123] The technical solutions shown in this application are described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other. For the same or similar content, such as the explanation of terms or nouns, and the explanation of steps, etc., different embodiments can refer to each other and will not be repeated.

[0124] FIG3 is a flow chart of a measurement reporting method provided in an embodiment of the present application, which is applied to a terminal device. As shown in FIG3 , the measurement reporting method includes:

[0125] S301: Send first layer 1 / layer 2 triggered mobility management LTM measurement related information, where the first LTM measurement related information includes LTM measurement related information.

[0126] In conjunction with the scenario example, the LTM measurement-related information includes a measurement result, which is used to determine the communication quality of the terminal device.

[0127] Optionally, the measurement result is obtained by performing measurement on the terminal device.

[0128] Optionally, LTM measurement related information is determined based on the current measurement result.

[0129] For example, for a terminal device in a mobile state or a terminal device whose communication quality changes, the measurement results at different times are different. Determining LTM measurement-related information based on the current measurement results can accurately reflect the current communication quality of the terminal device.

[0130] In a feasible implementation method, the first LTM measurement-related information includes at least one of the following: source cell-related information, the source cell-related information includes at least one of the following: cell index, signal quality, physical layer L1 measurement-related information, or radio resource management (Radio Resource Control, RRC) layer L3 measurement-related information; target cell-related information, the target cell-related information includes at least one of the following: cell index, signal quality, physical layer L1 measurement-related information, or RRC layer L3 measurement-related information; neighboring cell-related information, the neighboring cell-related information includes at least one of the following: cell index, signal quality, physical layer L1 measurement-related information, or RRC layer L3 measurement-related information; source beam-related information, the source beam-related information includes at least one of the following: beam index, transmission configuration indication state TCI state, TCI state index, or beam quality; target beam-related information, specifically including at least one of the following: beam index, TCI state, TCI state index, or beam quality; source synchronization signal block SSB index; target synchronization signal block SSB index.

[0131] The source cell is the cell where the terminal device was located before switching, the target cell is the cell to which the terminal device switches, and the neighboring cell is a cell within a preset range near the terminal device. The cell index is used to uniquely identify the cell. Signal quality is used to evaluate the communication performance provided by the cell. The beam index is used to uniquely identify the beam used by the cell. Beam quality is used to evaluate the communication performance of the beam, including the reference signal reception power or reference signal reception quality of the beam. The synchronization signal block is a signal used for cell synchronization and initial access. The terminal device obtains the cell's system information, time synchronization, and other necessary parameters through the synchronization signal block. The synchronization signal block index is used to uniquely identify the synchronization signal block. The transmission configuration indication state contains configuration information about the downlink reference signal and uplink reference signal, which is used to describe information about beamforming and spatial relationship configuration. Beamforming information includes information such as beam pointing or beam width. The terminal device uses this beamforming information to ensure correct signal reception and processing. The spatial relationship configuration information defines the spatial relationship between different reference signals. The terminal device uses this spatial relationship configuration information to predict and receive the beams of other signals. Information related to physical layer L1 measurements involves measuring and evaluating various parameters of received wireless signals. Terminal devices use information related to physical layer L1 measurements to assist in mobility management or select the best service cell. Network equipment can evaluate the quality of wireless links, adjust transmission parameters, optimize beam configuration, etc. based on information related to physical layer L1 measurements to ensure efficient and reliable communication. Information related to RRC layer L3 measurements focuses on performance evaluation at the network level. Information related to RRC layer L3 measurements can be collected and analyzed through a variety of network devices and tools. These devices and tools can be deployed at different levels and locations in the network to obtain comprehensive network performance data. The collected data can be used to generate network performance reports, diagnose network problems, optimize network configuration, etc. Based on information related to RRC layer L3 measurements, the best target cell for handover can be decided to ensure that the terminal device can maintain a stable communication connection.

[0132] Optionally, the cell index includes but is not limited to at least one of the following: a physical cell identifier PCI, a cell ID, or a cell configuration ID, etc.

[0133] The physical cell identifier is associated with the geographical location of the cell (eg, longitude and latitude or a network device address).

[0134] Optionally, the signal quality is the measurement result of the beam with the best communication quality in the cell or the weighted average of the measurement results of multiple beams. The multiple beams can be N beams with the best quality, where N is configured by the network or determined based on the terminal device implementation.

[0135] Optionally, the beam quality includes but is not limited to at least one of the following: a current measurement result of the beam, multiple recent measurement results of the beam, or a difference between a current measurement result of the beam and a previous measurement result.

[0136] For example, the network device can determine the degree of change in the measurement result through the most recent multiple measurement results of the beam, or the difference between the current measurement result of the beam and the last measurement result, thereby improving the accuracy of determining the communication quality of the terminal device.

[0137] Optionally, the first LTM measurement related information further includes but is not limited to: whether to perform L1 filtering or L1 filtering related parameters.

[0138] For example, filtering the signal can eliminate noise and interference, thereby improving the accuracy of the measurement result. Filtering-related parameters include but are not limited to at least one of the following: filter type, filter window size, filter threshold, or filter algorithm parameters.

[0139] Furthermore, in a feasible implementation, the physical layer L1 measurement-related information includes at least one of the following: physical layer L1 reference signal received power, physical layer L1 signal to interference plus noise ratio, or physical layer L1 reference signal received quality, whether there is an associated L3 measurement configuration, etc.; the RRC layer L3 measurement-related information includes at least one of the following: RRC layer L3 reference signal received power or RRC layer L3 signal to interference plus noise ratio. The associated L3 measurement is that the target frequency point of the L3 measurement is the same as the target frequency / time position and / or reference signal of the L1 measurement and / or the same subcarrier spacing.

[0140] The reference signal received power (RSRP) measures the power level of the received reference signal and is an important metric for evaluating wireless link quality. The reference signal received quality (RSRQ) measures the quality of the received reference signal, taking into account interference and other factors, and is used to assess the stability and reliability of the wireless link. The signal-to-interference-plus-noise ratio (SINR) is the ratio of the received useful signal to the total interference and noise, and is a key parameter for evaluating communication quality.

[0141] Optionally, the physical layer L1 measurement related information further includes but is not limited to: time of arrival (TOA), time difference of arrival (TDOA), or angle of arrival (AoA).

[0142] Optionally, the RRC layer L3 measurement related information further includes but is not limited to: data transmission rate, delay in transmission of measurement data in the network, packet loss rate, data capacity or network coverage, etc.

[0143] Optionally, the RRC layer L3 measurement related information further includes but is not limited to: measurement identities (MI) or measurement objects (MO), measurement results (MR), and quantity configuration.

[0144] Exemplarily, a measurement index associates a measurement object with a reporting configuration. The measurement object defines the specific wireless signal or network entity that the terminal device needs to measure, and the frequency / time position and subcarrier spacing of the reference signal for the measurement. The measurement object may include a serving cell or a neighboring cell, etc. The quantity configuration defines the measurement filter configuration used for all event measurements and related reporting, and the periodic reporting of the measurement, which may include the measurement quantity and the layer 3 filter factor.

[0145] Optionally, the physical layer L1 measurement related information corresponds to a cell index, a synchronization signal block index, or a transmission configuration indication state, etc. The RRC layer L3 measurement related information corresponds to a cell index, a synchronization signal block index, or a transmission configuration indication state, etc.

[0146] Optionally, the network device instructs the terminal device to perform RRC layer L3 measurement by sending RRC layer L3 measurement configuration.

[0147] In conjunction with the scenario example, in a wireless communication system, the RRC layer L3 measurement configuration refers to the parameters and settings configured by the network device for the terminal device to perform RRC layer L3 measurements. These configurations generally include measurement objects, and the measurement configuration defines how the terminal device measures and reports information about a specific cell or frequency. By determining whether RRC layer L3 measurements have been performed, the terminal device can determine the information of a known cell (Known cell) or an unknown cell (Unknown cell). A known cell is a cell that the terminal device has measured and stored in its measurement database, while an unknown cell is a cell that the terminal device has not yet measured. In the scenario of RRC layer L3 measurement failure caused by T304 timer expiration, if the T304 timer times out, it may be because the network device did not respond to the terminal device's measurement report in a timely manner, which may be due to the lack of advance RRC layer L3 measurement configuration. In this case, adding or updating the RRC layer L3 measurement configuration of the terminal device can solve the problem, thereby ensuring that the terminal can correctly perform measurement reporting when needed.

[0148] In a feasible implementation method, the network device determines whether the terminal device meets the first condition based on the first LTM measurement related information.

[0149] Combined with the scenario example, after the terminal device performs switching, the communication quality changes, and the communication quality related information is recorded in the first LTM measurement related information. The network device determines whether the current communication quality of the terminal device meets the first condition based on the first LTM measurement related information reported by the terminal device.

[0150] In a feasible implementation method, the network device determines a switching configuration based on whether the terminal device meets a first condition, where the switching configuration is used to instruct the terminal device to perform switching; and sends the switching configuration.

[0151] Taking the scenario example as an example, if the terminal device meets the first condition, it means that the communication quality of the target cell currently accessed by the terminal device can be optimized.

[0152] Furthermore, in a feasible implementation method, the first condition includes at least one of the following: the reference signal receiving power of the first cell is greater than the reference signal receiving power of the target cell, the signal to interference plus noise ratio of the first cell is greater than the signal to interference plus noise ratio of the target cell, or the signal strength of the first beam is greater than the signal strength of the target beam.

[0153] Combined with the scenario example, if the reference signal received power of the first cell is greater than the reference signal received power of the target cell, the signal to interference plus noise ratio of the first cell is greater than the signal to interference plus noise ratio of the target cell, or the signal strength of the first beam is greater than the signal strength of the target beam, it means that the communication quality of the first cell is better than that of the currently accessed target cell. For example, when the terminal device performs switching between two cells, a handover failure may occur, resulting in reconstruction to other cells. Other cells can provide communication services but the communication quality is not optimal. Or the handover failure causes the communication quality of other beams in the currently accessed target cell to be better than the target beam.

[0154] In a feasible implementation manner, the measurement reporting method further includes: receiving a reporting configuration, where the reporting configuration is used to instruct the terminal device to send first LTM measurement related information; and determining the first LTM measurement related information according to the reporting configuration.

[0155] Next, the determination of the first LTM measurement related information will be described with reference to FIG. 4 .

[0156] Figure 4 is a schematic diagram of determining first LTM measurement related information according to an embodiment of the present application. As shown in Figure 4, after receiving the reporting configuration, the terminal device determines the first LTM measurement related information in response to the reporting configuration.

[0157] In conjunction with the scenario example, the terminal device performs measurement and records the measurement result before receiving the reporting configuration. After receiving the reporting configuration, the terminal device determines the first LTM measurement related information in response to the reporting configuration.

[0158] A feasible implementation method, before receiving the reporting configuration, also includes: sending first information, where the first information is used to indicate to the network device that the terminal device has LTM measurement related information.

[0159] Next, the first information will be described with reference to FIG5 .

[0160] Figure 5 is a schematic diagram of the first information provided in an embodiment of the present application. As shown in Figure 5, the terminal device sends the first information, which indicates to the network device through the first information that the terminal device has recorded the first LTM measurement-related information. The network device can use the first information to determine that the first LTM measurement-related information of the terminal device is available. Based on this, the network device sends a reporting configuration to instruct the terminal device to send the first LTM measurement-related information.

[0161] In this feasible implementation, sending the first information can ensure that the terminal device can send the first LTM measurement-related information in response to the reporting configuration, thereby improving the reliability of the measurement report.

[0162] A feasible implementation method is to send the first information, including: sending the first information through RRC signaling.

[0163] Exemplarily, the first information is sent via 1-bit RRC signaling, where the RRC signaling includes but is not limited to RRCConnectionSetupComplete, RRCSetupComplete, RRCConnectionResumeComplete, or RRCResumeComplete message during connection establishment.

[0164] It should be noted that the present invention does not limit the signaling type for sending the first information.

[0165] In a feasible implementation manner, the measurement reporting method further includes: receiving a measurement configuration, where the measurement configuration is used to instruct the terminal device to perform measurement; performing the measurement, and obtaining a measurement result list.

[0166] The measurement configuration is described below with reference to FIG6 .

[0167] Figure 6 is a schematic diagram of a measurement configuration provided by an embodiment of the present application. As shown in Figure 6, the first LTM measurement related information is determined based on the measurement result, and the network device sends the measurement configuration to the terminal device before sending the reporting configuration, and instructs the terminal device to perform the measurement through the measurement configuration.

[0168] In this feasible implementation method, the measurement configuration instructs the terminal device to perform measurements to obtain a measurement result list, which can ensure that the terminal device can determine the first LTM measurement-related information based on the measurement results after subsequently receiving the reporting configuration, thereby improving the effectiveness of the measurement reporting.

[0169] In a feasible implementation manner, the measurement reporting method further includes: determining a measurement result list, where the measurement result list includes one or more measurement results and a measurement time corresponding to each measurement result.

[0170] In this scenario example, the measurement result list includes measurement results at multiple times, along with the measurement time corresponding to each measurement result. By recording the measurement time, the first LTM measurement-related information can be determined based on the latest measurement result, improving the accuracy of determining the first LTM measurement-related information.

[0171] Optionally, for physical layer L1 measurement results, the measurement result list includes the measurement duration. The first LTM measurement-related information includes the measurement duration or the duration since the last measurement report. It is understood that the network device can determine the terminal device's movement speed and direction based on the measurement duration, thereby more accurately predicting the terminal device's future location and behavior.

[0172] In this scenario example, the measurement result list includes measurement results at a specific moment. For devices that do not move frequently, where the communication quality does not change significantly over a period of time, frequent measurements are not required, saving measurement resources.

[0173] In a feasible implementation manner, the measurement result is obtained by performing measurement after each handover is completed, or by performing measurement every preset time period.

[0174] In this scenario example, a terminal device switches from a source cell to a target cell to complete the handover. The measurement results obtained after the handover are used to determine whether the target cell currently accessed by the terminal device is the cell with the best communication quality, thereby optimizing communication quality based on the measurement results. Measurement results obtained at preset intervals can be used to determine whether the cell currently accessed by the terminal device is the cell with the best communication quality, allowing the terminal device to perform a handover in a timely manner when a cell switch is required.

[0175] In this feasible implementation, multiple measurement triggering modes are set, so that switching can be performed in a timely manner, thereby optimizing the communication quality of the terminal device in a timely manner.

[0176] In a feasible implementation method, the measurement reporting method also includes: determining a first measurement result from the measurement result list, the measurement time corresponding to the first measurement result is later than any time in the measurement result list, or the measurement time corresponding to the first measurement result is a time before the time of receiving the reporting configuration; and determining the first LTM measurement-related information based on the first measurement result.

[0177] Combined with the scenario example, the measurement results are sorted in order from near to far according to the measurement time. The measurement result with the latest measurement time can accurately reflect the current communication quality of the terminal device. Compared with other measurement results in the measurement result list, the first measurement result corresponds to the measurement time closest to the current time. Based on the first measurement result, the first LTM measurement related information determined can accurately determine the current communication quality of the terminal device. Optimization on this basis can effectively improve the communication quality of the terminal device.

[0178] In a feasible implementation manner, the reporting configuration includes at least one of the following: a first sending indication; a first timer; period information; or a second sending indication.

[0179] The first sending instruction is used to instruct the terminal device to immediately send the first LTM measurement related information. The first timer is used to instruct the terminal device to delay sending the first LTM measurement related information. The second sending instruction is used to instruct the terminal device to send the first LTM measurement related information according to a predefined rule.

[0180] Exemplarily, for any specific content of the reporting configuration, the first LTM measurement related information is sent through a corresponding solution.

[0181] Next, various solutions for sending the first LTM measurement related information are exemplified respectively.

[0182] Embodiment 1: The reporting configuration includes a first sending instruction.

[0183] A feasible implementation method is to send the first LTM measurement related information, including: receiving the first sending instruction, and replying the first LTM measurement related information.

[0184] Next, the sending of the first LTM measurement related information provided by the first embodiment of the present invention will be described with reference to FIG. 7 .

[0185] Figure 7 is a schematic diagram of sending first LTM measurement-related information provided in an embodiment of the present application. As shown in Figure 7, the network device sends a first sending indication to the terminal device, and the terminal device responds to the first sending indication and replies to the network device with the first LTM measurement-related information at the moment of receiving the first sending indication.

[0186] Combined with the scenario example, for the one-time reporting scenario, that is, the network device only requires the terminal device to report LTM measurement-related information once, by sending a first sending indication, the terminal device can immediately reply with the current first LTM measurement-related information, thereby improving the measurement reporting efficiency.

[0187] Embodiment 2: The reporting configuration includes a first sending instruction and a first timer.

[0188] A feasible implementation method is to send the first LTM measurement related information, including: receiving the first sending instruction and the first timer, and replying the first LTM measurement related information after the duration corresponding to the first timer has passed.

[0189] Next, the sending of the first LTM measurement related information provided by the second embodiment of the present invention will be described with reference to FIG8 .

[0190] Figure 8 is a schematic diagram of sending the first LTM measurement-related information provided in an embodiment of the present application. As shown in Figure 8, the network device sends a first sending indication and a first timer to the terminal device. The terminal device responds to the first sending indication and determines the duration corresponding to the first timer. After the duration corresponding to the first timer has passed, the terminal device replies to the first LTM measurement-related information.

[0191] Combined with the scenario example, the network device predicts that the communication quality of the terminal device will change at a future moment or predicts that the terminal device will switch at a future moment, then the first timer is used to instruct the terminal to delay sending the first LTM measurement-related information. The delayed sending of the first LTM measurement-related information can reflect the communication quality of the terminal device at the predicted future moment, thereby accurately performing corresponding optimization based on the communication quality.

[0192] Embodiment 3: The reporting configuration includes period information.

[0193] A feasible implementation method is to send the first LTM measurement related information, including: receiving the period information, and replying the first LTM measurement related information every period duration corresponding to the period information.

[0194] Next, the sending of the first LTM measurement related information provided by the third embodiment of the present invention will be described with reference to FIG. 9 .

[0195] Figure 9 is a schematic diagram of sending the first LTM measurement-related information. As shown in Figure 9, the network device sends periodic information to the terminal device. The terminal device responds to the periodic information and determines the duration corresponding to the periodic information. The terminal device replies with the first LTM measurement-related information every periodic duration.

[0196] Combined with the scenario example, for terminal devices that frequently move, frequently switch, or whose communication quality changes frequently, the network device instructs the terminal device to perform measurement reporting multiple times, which can timely optimize the communication quality of the terminal device and improve communication reliability.

[0197] A feasible implementation method is that the cycle information includes the cycle start time and the cycle end time, and the cycle duration is the duration between the cycle start time and the cycle end time; or, the cycle information includes a second timer; the cycle duration is the duration corresponding to the second timer.

[0198] In conjunction with a scenario example, if the cycle information includes the cycle start time and the cycle end time, for example, the cycle start time is 10:00 and the cycle end time is 10:10, then the cycle duration is determined to be 10 minutes, the first cycle is from 10:00 to 10:10, the second cycle is from 10:10 to 10:20, and so on. The terminal device sends the first LTM measurement-related information at 10:10, 10:20, 10:30, etc. If the cycle information includes a second timer, the duration corresponding to the second timer is determined as the cycle duration, the current time is determined as the cycle start time, and the time after the current time exceeds the cycle duration is determined as the cycle end time. And so on, multiple cycles are obtained.

[0199] In this feasible implementation, various cycle determination methods can be used to adapt to various application scenarios.

[0200] Embodiment 4: The reporting configuration includes period information and a first timer.

[0201] A feasible implementation method is to send the first LTM measurement related information, including: receiving the period information and the first timer, and after the duration corresponding to the first timer has passed, replying the first LTM measurement related information every period duration corresponding to the period information.

[0202] Next, the sending of the first LTM measurement related information provided by the fourth embodiment of the present invention will be described with reference to FIG. 10 .

[0203] Figure 10 is a schematic diagram of sending first LTM measurement-related information provided in an embodiment of the present application. As shown in Figure 10, the network device sends periodic information and a first timer to the terminal device. The terminal device responds to the periodic information, determines the duration corresponding to the periodic information and the duration corresponding to the first timer. After the duration corresponding to the first timer has passed at the moment of receiving the periodic information and the first timer, the terminal device replies with the first LTM measurement-related information every periodic duration.

[0204] It should be noted that the terminal device can determine the duration corresponding to the periodic information and the duration corresponding to the first timer simultaneously or sequentially, and the order of sequential execution is not limited.

[0205] In combination with the scenario example, the network device predicts that the communication quality of the terminal device will change frequently after the time corresponding to the first timer has passed, and then sends periodic information and the first timer to instruct the terminal device to perform measurement reporting.

[0206] Embodiment 5: The reporting configuration includes a second sending instruction.
