The first information can be used to assist the network device in determining whether to allow the terminal to perform a handover to the first cell. This method of assisting the network device in determining whether to allow the terminal to perform a handover to the first cell based on the predicted dwell time of the terminal in the first cell can avoid frequent handovers caused by the terminal's dwell time in the first cell being too short, thereby reducing signaling overhead and service interruption caused by frequent handovers, thereby improving network performance.

[0133] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).
[0134] 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.
[0135] In some embodiments, during a traditional handover process, the network configures the UE to perform measurements. Based on the measurement results reported by the UE, the network sends a handover request to the target cell. After the target cell confirms completion, the network 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.
[0136] In some embodiments, the UE performs measurements according to the network configuration, where the measurement configuration includes a measurement object, a report configuration, and a quantity configuration.
[0137] In some embodiments, the measurement object indicates the frequency to be measured, and may include multiple access technologies, including NR and LTE. Each measurement object is bound to a measurement object index identifier (measObject ID).
[0138] In some embodiments, the reporting configuration indicates the type of reporting by the UE, including periodic reporting and event-based reporting.
[0139] In some embodiments, the measurement report may carry the identifier and measurement result of the cell that triggered the reporting event and / or the identifiers and measurement results of the N cells with the best measurement results.
[0140] In some embodiments, the UE's time of stay (ToS) in a cell is used as a measure of handover performance. If the ToS is too short, frequent handovers occur, leading to significant signaling overhead and connection interruptions, which should be avoided. The ToS can be the time between handovers.
[0141] In some embodiments, in order to improve the robustness of handover, 5G proposes conditional handover (CHO), that is, the network can configure the CHO handover command for the UE in advance, including the handover target cell configuration and the handover trigger condition, where the handover target cell configuration is the reconfiguration message provided by the target cell. The UE stores the received CHO handover command, performs RRM measurement, and determines whether the handover conditions are met. When the handover trigger condition is met, the UE performs the handover on its own. The handover is performed by performing synchronous reconfiguration (reconfiguration with sync). This can avoid the failure of the wireless link caused by the base station sending the handover command too late.
[0142] In some embodiments, if the UE is moving at high speed, a handover will be performed when the target cell signal strength improves. However, the cell signal will quickly deteriorate, and the UE will need to switch to the next cell. If the ToS of this cell is too short, frequent handovers will occur. However, since handovers are based on the current channel quality, frequent handovers caused by a too short ToS cannot be avoided. In view of this, the embodiments of the present disclosure provide a communication method, terminal, network device, communication system, and storage medium that can avoid frequent handovers caused by a too short ToS.
[0143] 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:
[0144] Step S201 : The network device 102 sends second information to the terminal 101 .
[0145] In some embodiments, terminal 101 receives second information.
[0146] In some embodiments, the second information is used to configure a reporting condition for the terminal. For example, the network device sends the second information, the second information including the reporting condition. The terminal receives the second information and obtains the reporting condition.
[0147] Step S202: Terminal 101 obtains predicted information of the terminal's stay time in the first cell.
[0148] In some embodiments, the terminal uses a trained AI model to predict the terminal's residence time in the first cell based on information such as the terminal's current geographic location, movement speed, coverage of the first cell, current network environment, and wireless network environment over a recent period of time. The AI model can be installed on the terminal or on another entity capable of communicating with the terminal.
[0149] In some embodiments, the terminal uses other prediction algorithms to predict the terminal's stay time in the first cell based on information such as the terminal's current geographical location, moving speed, coverage of the first cell, current network environment, and wireless network environment in the previous period.
[0150] In some embodiments, the name of the first cell is not limited, and it can be, for example, a target cell, a candidate cell, etc.
[0151] In some embodiments, the first cell may be a cell that meets certain conditions, or the first cell may be a cell designated in a specific scenario.
[0152] In some embodiments, before step S202, the process may include: determining a first cell, where the first cell may be selected from at least one of the following:
[0153] The cell indicated by the network device;
[0154] cells in CHO configuration;
[0155] The cell in the handover command;
[0156] The cell carried in the measurement report information.
[0157] In some embodiments, the network device may designate a first cell. For example, the network device sends a cell identifier to the terminal, and the terminal may determine the cell indicated by the network device based on the cell identifier. The cell indicated by the network device may serve as the first cell.
[0158] In some embodiments, in a conditional handover (CHO) scenario, a cell in a CHO configuration pre-configured by a network device for a UE may be used as a first cell. For example, the terminal may determine the cells included in the CHO configuration by reading and parsing the CHO configuration. The cell in the CHO configuration may be used as the first cell.
[0159] In some embodiments, during some handover processes, the network device configures the UE to perform measurements. Based on the measurement results reported by the UE, the network device sends a handover request to the handover target cell. After the target cell confirms the completion, the network device sends a handover command (Reconfiguration with sync) to the UE. The command carries the configuration information of one (or more) target cells. Therefore, in some embodiments, in a scenario where the terminal receives a handover command, the terminal can determine the cell included in the handover command by receiving and parsing the handover command. The cell in the handover command can be used as the first cell. In some embodiments, the cell in the measurement result reported by the UE can be used as the first cell. For example, the terminal can use the cell carried in the measurement report information as the first cell.
[0160] In some embodiments, the stay time information includes but is not limited to the first time point and the first duration.
[0161] Optionally, the dwell time information includes a first time point, wherein the first time point is a time point at which the terminal leaves the first cell after accessing the first cell. Optionally, the terminal may access the first cell through cell handover. Optionally, the terminal may leave the first cell through cell handover.
[0162] Optionally, the dwell time information includes a first duration. Optionally, the first duration is the duration that the terminal remains in the first cell after accessing the first cell. Optionally, the first duration is the duration that the terminal remains in the first cell after accessing the first cell. Optionally, the terminal may access the first cell through handover. Optionally, the terminal may leave the first cell through handover.
[0163] In step S203 , the terminal 101 determines that the residence time information meets the reporting condition, and sends first information to the network device 102 .
[0164] In some embodiments, a network device receives first information.
[0165] In some embodiments, the first information is used to assist the network device in determining whether to allow the terminal to perform handover to the first cell.
[0166] In some embodiments, the first information is used to notify / request the network device to allow the terminal to perform handover to the first cell.
[0167] In some embodiments, the first information is used to notify the network device terminal not to switch to the first cell.
[0168] In some embodiments, the first information is used to request the network device to prevent / terminate / prohibit the terminal from switching to the first cell.
[0169] In some embodiments, the first information is used to request the network device to increase or decrease the priority of handover of the terminal to the first cell.
[0170] In some embodiments, the name of the first information is not limited, and it can be, for example, a first instruction signal, a switching assistance signal, a switching request signal, a switching stop signal, etc.
[0171] In some embodiments, the first information includes at least one of the following:
[0172] an identifier of the first cell;
[0173] Time information of staying in the first cell.
[0174] Optionally, the time information includes at least one of a first time point, a first duration, a stay level corresponding to the first time point, and a stay level corresponding to the first duration.
[0175] In some embodiments, the terminal determines the stay level of the first duration / first time point according to the predicted stay time information. The correspondence between the level and the first duration / first time point may be specified by a protocol or provided by a network device.
[0176] For example, the correspondence between the first time point and the stay level is indicated by the network device to the terminal; or, the correspondence between the first time point and the stay level is specified by a protocol.
[0177] For example, the correspondence between the first duration and the stay level is indicated by the network device to the terminal; or, the correspondence between the duration and the stay level is specified by a protocol.
[0178] In some embodiments, there may be multiple first time points, and accordingly, there may be multiple stay levels.
[0179] In some embodiments, different first time points may correspond to different stay levels. For example, the later the time represented by the first time point, the higher the corresponding stay level, and the higher the stay level, the higher the priority / likelihood of switching to the corresponding first cell.
[0180] In some embodiments, there may be multiple first durations, and accordingly, there may be multiple stay levels.
[0181] In some embodiments, different first durations may correspond to different stay levels. For example, a larger first duration corresponds to a higher stay level, and a higher stay level indicates a higher priority / likelihood of switching to the corresponding first cell.
[0182] In some embodiments, before step S203, it may be determined whether to send the first information to the network device based on the residence time information, for example, whether the residence time information satisfies / meets a reporting condition.
[0183] In some embodiments, if it is determined that the residence time information does not meet the reporting condition, the first information is not sent to the network device.
[0184] In some embodiments, when it is determined that the residence time information meets the reporting condition, the first information is sent to the network device.
[0185] In some embodiments, the name of the reporting condition is not limited, and it can be, for example, a specific condition, a preset condition, etc.
[0186] In some embodiments, different cells and / or different cell frequencies may correspond to the same or different reporting conditions. Alternatively, different cells may correspond to the same or different cell frequencies. For example, the reporting condition may correspond to the deployed (cell) frequency of the cell, and the terminal may determine the corresponding reporting condition based on the (cell) frequency of the first cell.
[0187] In some embodiments, the reporting condition includes whether the first duration in the dwell time information is greater than or less than a duration threshold. Optionally, the duration threshold may be indicated by a network device, or may be specified by a protocol, or may be a default value configured locally on the terminal, or may be calculated using a specific algorithm.
[0188] In some embodiments, the reporting condition corresponding to the first specific cell includes: a first duration in the residence time information is greater than a duration threshold. Optionally, the first specific cell is at least one of a cell indicated by the network device, a cell in the CHO configuration, and a cell in the measurement reporting information.
[0189] For example, if the first cell is at least one of a cell indicated by the network device, a cell in the CHO configuration, and a cell in the measurement reporting information, then if it is determined that the first duration in the dwell time information is greater than the duration threshold, it can be determined that the reporting condition is met, and first information can be sent to the network device. The first information is used to indicate that the network device can perform a handover to the first cell. Upon receiving the first information, the network device can execute the following step S204.
[0190] In some embodiments, the reporting condition corresponding to at least one of the cell indicated by the network device, the cell in the CHO configuration, and the cell in the measurement reporting information includes: the first duration in the residence time information is less than the duration threshold; accordingly, the first information is used to notify the network device to lower the priority of the terminal's handover to the first cell or prohibit the terminal from handing over to the first cell. For example, if the first cell is at least one of the cell indicated by the network device, the cell in the CHO configuration, and the cell in the measurement reporting information, then when it is determined that the first duration in the residence time information is less than the duration threshold, it can be determined that the reporting condition is met, and the first information can be sent to the network device. Upon receiving the first information, the network device can lower the priority of the terminal's handover to the first cell, or prohibit the terminal from handing over to the first cell.
[0191] In some embodiments, the reporting condition corresponding to the second specific cell includes: the first duration in the dwell time information is less than a duration threshold. Optionally, the second specific cell is a cell in the handover command.
[0192] For example, if the first cell is the cell specified in the handover command, then if the first duration in the dwell time information is determined to be less than the duration threshold, the reporting condition may be determined to be met, and a first message may be sent to the network device. The first message may be used to instruct / request the network device to prevent / stop / terminate the terminal from performing a handover to the first cell. Alternatively, the first message may be used to notify the network device that the terminal should not perform a handover to the first cell. Upon receiving the first message, the network device executes step S205.
[0193] In some embodiments, the reporting condition includes whether the first time point in the dwell time information is earlier or later than a time point threshold. Optionally, the time point threshold may be indicated by a network device, or may be specified by a protocol, or the duration threshold may be a default value configured locally on the terminal, or the time point threshold may be calculated using a specific algorithm.
[0194] In some embodiments, the reporting condition corresponding to the first specific cell includes: a first time point in the dwell time information is later than a time point threshold. Optionally, the first specific cell is at least one of a cell indicated by the network device, a cell in the CHO configuration, and a cell in the measurement reporting information.
[0195] For example, if the first cell is at least one of a cell indicated by the network device, a cell in the CHO configuration, and a cell in the measurement reporting information, then if it is determined that the first time point in the dwell time information is later than the time point threshold, the reporting condition may be determined to be met, and first information may be sent to the network device. The first information indicates that the network device can perform a handover to the first cell. The network device receives the first information and executes step S204.
[0196] In some embodiments, the reporting condition corresponding to at least one of the cell indicated by the network device, the cell in the CHO configuration, and the cell in the measurement reporting information includes: the first time point in the residence time information is earlier than the time point threshold; accordingly, the first information is used to notify the network device to lower the priority of the terminal's handover to the first cell or prohibit the terminal from handing over to the first cell. For example, if the first cell is at least one of the cell indicated by the network device, the cell in the CHO configuration, and the cell in the measurement reporting information, then when it is determined that the first time point in the residence time information is earlier than the time point threshold, it can be determined that the reporting condition is met, and the first information can be sent to the network device. Upon receiving the first information, the network device can lower the priority of the terminal's handover to the first cell, or prohibit the terminal from handing over to the first cell.
[0197] In some embodiments, the reporting condition corresponding to the second specific cell includes: the first time point in the dwell time information is earlier than a time point threshold. Optionally, the second specific cell is a cell in the handover command.
[0198] For example, if the first cell is the cell specified in the handover command, then if the first time point in the dwell time information is determined to be earlier than the time point threshold, the reporting condition may be determined to be met, and a first message may be sent to the network device. The first message may be used to instruct / request the network device to prevent / stop / terminate the terminal from performing a handover to the first cell. Alternatively, the first message may be used to notify the network device that the terminal should not perform a handover to the first cell. Upon receiving the first message, the network device executes step S205.
[0199] In some embodiments, if the first cell is the cell in the handover command and it is determined that the reporting condition is met, the terminal may not switch to the first cell.
[0200] In step S204 , the network device 102 determines that the first cell corresponding to the first information is a first specific cell, and allows the terminal 101 to switch to the first cell.
[0201] In some embodiments, the network device determines that the first cell corresponding to the first information is a first specific cell, indicating that the first information is used by the terminal to notify the network device that it can switch to the first cell. In this case, the network device can allow the terminal to switch to the first cell.
[0202] In some embodiments, the implementation of the network device allowing the terminal to switch to the first cell may include: the network device may allow the terminal to switch to the first cell preferentially.
[0203] In step S205 , the network device 102 determines that the first cell corresponding to the first information is the second specific cell, and prevents the terminal 101 from switching to the first cell.
[0204] In some embodiments, the network device determines that the first cell corresponding to the first information is the second specific cell, indicating that the first information is used by the terminal to notify the network device that the terminal does not switch to the first cell, or indicating that the first information is used by the terminal to request the network device to prevent / terminate the terminal from switching to the first cell. In this case, the network device can prevent / terminate the terminal from switching to the first cell.
