Based on the measurement results reported by the UE, the network sends a handover request to the target cell. After the target cell confirms the completion, it sends a handover command (Reconfiguration with sync) to the UE, carrying configuration information of the target cell. The configuration information may include bearer configuration, MAC configuration, and random access configuration. After receiving the handover command, the UE synchronizes with the target cell, initiates a random access procedure to access the target cell, and begins using the carried target cell configuration.

[0119] In some embodiments, in order to reduce the UE's measurements of neighboring cells, the network may configure an s-measure configuration for the UE, which carries a threshold value for RSRP (RSRP: Reference Signal Received Power). RSRP can be obtained by measuring SSB or CSI-RS. When the RSRP measured by the UE for the serving cell is higher than the threshold value, the UE may not measure the neighboring cells. It should be explained that in LTE, the use of the concept of s-Measure can reduce the UE's neighboring cell measurement overhead. When the PCell measurement performed by the UE is higher than the s-Measure value configured by the network, the UE suppresses the execution of neighboring cell measurements.

[0120] In some embodiments, machine learning algorithms are one of the most important implementation methods of artificial intelligence technology. Machine learning can generate models from large amounts of training data, which can then be used to predict events. In many fields, models trained using machine learning can produce highly accurate predictions.

[0121] In some embodiments, although the UE can determine whether to measure neighboring cells based on s-measure and reduce the number of neighboring cell measurements, the UE must always measure the RSRP of the serving cell to determine whether to measure neighboring cells. The UE's measurement of the serving cell consumes energy.

[0122] In view of this, embodiments of the present disclosure provide a communication method, terminal, network device, communication system, and storage medium, which can reduce the UE's measurements of the serving cell, thereby reducing the UE's energy consumption.

[0123] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0124] In step S201 , the network device 102 sends a first instruction to the terminal 101 .

[0125] In some embodiments, terminal 101 receives a first indication.

[0126] In some embodiments, the first indication is used to indicate whether the terminal is allowed to predict the radio channel quality of the first cell to obtain a first prediction result.

[0127] In some embodiments, the first indication is used to indicate whether the terminal is allowed to determine whether to measure the second cell according to the first prediction result.

[0128] In some embodiments, the first indication is used to indicate that the terminal is allowed to predict the radio channel quality of the first cell to obtain a first prediction result, and indicates that the terminal is allowed to determine whether to measure the second cell based on the first prediction result.

[0129] In some embodiments, the first indication is used to indicate whether the terminal is allowed to activate the first function. Optionally, the first function is a function of the terminal predicting the radio channel quality of the first cell to obtain a first prediction result, and / or a function of the terminal determining whether to measure the second cell based on the first prediction result.

[0130] In some embodiments, the name of the first indication is not limited, and it can be, for example, a function activation indication, a function enabling instruction, etc.

[0131] In some embodiments, the first cell may be a serving cell of the terminal, and the second cell may be a neighboring cell (adjacent cell) of the serving cell of the terminal.

[0132] In some embodiments, a measurement configuration may be configured on the terminal 101. Optionally, the measurement configuration includes a measurement object. Optionally, the measurement object indicates a first frequency to be measured. In some embodiments, the neighboring cell is a cell corresponding to the first frequency indicated by the measurement object.

[0133] In some embodiments, application scenarios of the communication method of the present disclosure include but are not limited to 4G and 5G scenarios.

[0134] For example, in a 5G scenario, the measurement object may refer to an NR measurement object, and accordingly, the first frequency may refer to a frequency of a reference signal, where the reference signal includes a synchronization signal block SSB and / or a channel state information reference signal CSI-RS.

[0135] For example, in a 4G scenario, the measurement object may refer to an LTE measurement object, and accordingly, the first frequency may refer to an E-UTRA carrier frequency.

[0136] For example, the communication method disclosed herein can also be applied to the scenario of the next generation mobile communication technology. Accordingly, the measurement object may refer to the measurement object specified / specified by the next generation mobile communication technology, and accordingly, the first frequency may refer to the frequency or frequency point specified / specified by the next generation mobile communication technology.

[0137] Step S202: Terminal 101 predicts the quality of the wireless channel of the first cell.

[0138] In some embodiments, the implementation method of the terminal predicting the wireless channel quality of the first cell includes: predicting a first prediction result corresponding to the first cell at a second moment based on a first measurement result obtained by measuring the third cell at a first moment.

[0139] It should be noted that the first measurement result is a real measurement result obtained by performing cell measurement on the third cell.

[0140] Optionally, the third cell is the first cell. Optionally, the first moment is earlier than the second moment. For example, based on a first measurement result obtained by measuring the first cell before the second moment, a first prediction result corresponding to the first cell at the second moment can be predicted. For example, based on a historical first measurement result of the first cell, a first prediction result corresponding to the first cell at the current moment or a future moment can be predicted.

[0141] Optionally, the third cell is a cell other than the first cell. Optionally, the first moment is earlier than or equal to the second moment. The third cell and the first cell may be co-frequency or inter-frequency cells, which is not limited in this disclosure. For example, based on a first measurement result obtained by measuring the third cell at a first moment, a first prediction result corresponding to the first cell at or after the first moment can be predicted. For example, based on a historical first measurement result of the third cell, a first prediction result corresponding to the first cell at the current moment or a future moment can be predicted.

[0142] In some embodiments, the terminal predicts the wireless channel quality of the first cell by implementing the method of predicting the wireless channel quality of the first cell, including predicting the first prediction result corresponding to the first cell at the second moment based on the second prediction result obtained by predicting the wireless channel quality of the third cell at the first moment.

[0143] Optionally, the third cell refers to the first cell. Optionally, the first moment is earlier than the second moment. For example, based on a second prediction result obtained by predicting the first cell before the second moment, a first prediction result corresponding to the first cell at the second moment can be predicted. For example, based on a historical second prediction result of the first cell, a first prediction result corresponding to the first cell at the current moment or a future moment can be predicted.

[0144] Optionally, the third cell is a cell other than the first cell. Optionally, the first moment is earlier than or equal to the second moment. For example, based on the second prediction result obtained by predicting the third cell at the first moment, a first prediction result corresponding to the first cell at or after the first moment can be predicted. For example, based on the second historical prediction result of the third cell, a first prediction result corresponding to the first cell at the current moment or a future moment can be predicted.

[0145] In some embodiments, the terminal may predict the wireless channel quality of the first cell through a prediction model.

[0146] In some embodiments, the prediction model is a trained AI model. The prediction model can be configured on terminal 101, or the prediction model can be configured on other electronic devices that can communicate with terminal 101, such as other terminals other than terminal 101, or network devices.

[0147] It should be noted that, in addition to predicting the radio channel quality of the first cell using the prediction model, the terminal 101 may also predict the radio channel quality of the first cell using other prediction methods, such as using a prediction algorithm.

[0148] It should be noted that after step S202, step S203 or step S206 is executed.

[0149] In some embodiments, in step S202, the terminal predicts the radio channel quality of the first cell and may obtain a first prediction result. If the first prediction result is obtained, step S203 is executed.

[0150] In some embodiments, in step S202, the terminal may fail to obtain a first prediction result when predicting the radio channel quality of the first cell. For example, if the terminal's current remaining battery power is insufficient to support the terminal's prediction of the radio channel quality of the first cell, the first prediction result may not be obtained. For example, when using a prediction model for prediction, the first prediction result may not be obtained due to incomplete input data to the prediction model.

[0151] In some embodiments, if the first prediction result cannot be obtained, step S206 is executed.

[0152] Step S203: If the terminal 101 predicts and obtains a first prediction result, a first threshold value is determined.

[0153] In some embodiments, the first prediction result obtained by the terminal includes at least one of the following:

[0154] Reference signal received power RSRP;

[0155] Reference signal received quality RSRQ;

[0156] Signal to Interference and Noise Ratio SINR.

[0157] For example, the first prediction result is RSRP.

[0158] In some embodiments, the name of the first prediction result is not limited, and it is, for example, a predicted cell measurement result.

[0159] In some embodiments, the first threshold value may be used to evaluate the quality of the radio channel of the first cell. The name of the first threshold value is not limited, and it may be, for example, an "s-Measure" parameter.

[0160] In some embodiments, different models may have differences due to factors such as training data, training duration, and training methods. For example, models with the same function may have different accuracy rates. Therefore, in some embodiments, if a prediction model corresponds to a threshold value, then the method for determining the first threshold value may include determining the threshold value corresponding to the prediction model that outputs the first prediction result as the first threshold value.

[0161] In some embodiments, the correspondence between the prediction model and the threshold value is indicated by the network device and / or specified by the protocol.

[0162] In some embodiments, since the confidence level of each prediction model output result may also be different, in some embodiments, if one prediction model output result corresponds to one confidence level (one prediction model output results in one prediction model output result), and one confidence level corresponds to one threshold value, then the implementation method for determining the first threshold value may include: determining the threshold value corresponding to the confidence level of the first prediction result as the first threshold value. Alternatively, the confidence level of the first prediction result may be output by the prediction model simultaneously with the first prediction result output.

[0163] It should be noted that confidence can be understood as credibility, accuracy, etc.

[0164] In some embodiments, the correspondence between the confidence level and the threshold value is indicated by the network device and / or specified by the protocol.

[0165] After step S203, step S204 or step S205 is selected for execution.

[0166] Step S204: When the first prediction result is greater than the first threshold, the terminal 101 does not measure the second cell.

[0167] In some embodiments, the terminal may determine whether to measure the second cell based on the magnitude relationship between the first prediction result and the first threshold. For example, if the first prediction result is greater than the first threshold, the terminal does not measure the second cell. Not measuring the second cell can be understood as refraining from performing measurements on the second cell.

[0168] Step S205: When the first prediction result is less than or equal to the first threshold, the terminal 101 measures the second cell.

[0169] In some embodiments, the terminal may determine whether to measure the second cell based on a magnitude relationship between the first prediction result and the first threshold value. For example, the terminal measures the second cell if the first prediction result is less than or equal to the first threshold value.

[0170] Step S206: If the terminal 101 cannot obtain the first prediction result, it measures the first cell to obtain a second measurement result.

[0171] In some embodiments, if the terminal cannot obtain the first prediction result, the terminal measures the first cell to obtain a second measurement result. Optionally, the second measurement result includes at least one of the following:

[0172] Reference signal received power RSRP;

[0173] Reference signal received quality RSRQ;

[0174] Signal to Interference and Noise Ratio SINR.

[0175] For example, the second measurement result is RSRP.

[0176] In some embodiments, whether to measure the second cell may be determined based on a magnitude relationship between the second measurement result and the second threshold value.

[0177] After step S206, step S207 or step S208 is selected for execution.

[0178] Step S207: When the second measurement result is greater than the second threshold, the terminal 101 does not measure the second cell.

[0179] In some embodiments, the second threshold value may be used to evaluate the quality of the radio channel of the first cell. The name of the second threshold value is not limited, and it may be, for example, an "s-Measure" parameter.

[0180] In some embodiments, the second threshold value is indicated by the network device or specified by the protocol.

[0181] In some embodiments, the second threshold value and the first threshold value may be interchangeable.

[0182] Step S208: When the second measurement result is less than or equal to the second threshold, the terminal 101 measures the second cell.
