[0109] 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.

[0111] 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.

[0112] Conditional handover is a mobility enhancement technology introduced in 3GPP (3rd Generation Partnership Project, or 3GPP) R16. Compared to traditional handover methods, conditional handover improves handover success rates. During the preparation phase of conditional handover, the source network device prepares several candidate cells and sends handover request messages to each of them. The terminal device then selects one of these candidate cells to handover to.

[0113] In related technologies, the source network device sends the execution conditions of the handover to the terminal device, and the terminal device performs the handover according to the execution conditions. However, if the execution conditions are unreasonable, the terminal device may not be able to successfully perform the handover, and may also cause the communication link to fail, affecting the terminal device's communication.

[0114] Figure 2 is a schematic diagram of triggering execution conditions provided in an embodiment of the present application. As shown in Figure 2, a network device sends a handover execution condition to a terminal device, and the terminal device performs the handover according to the execution condition. Specifically, the terminal device evaluates the execution condition in real time. If the terminal device meets the execution condition, indicating that the current communication quality needs to be optimized, the handover is triggered to improve the communication quality.

[0115] 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.

[0116] FIG3 is a flow chart of an information transmission method provided in an embodiment of the present application. As shown in FIG3 , the information transmission method includes:

[0117] S301. Send relevant information of conditional switching, where the conditional switching is conditional switching with a candidate primary and secondary cell group.

[0118] Among them, the conditional switching with the candidate primary and secondary cell group is that the terminal device performs switching when the terminal meets the execution conditions of the primary cell and / or the execution conditions of the primary and secondary cells.

[0119] Using a scenario example, a terminal device in a dual-link scenario can simultaneously use the radio resources of two nodes, improving radio resource utilization and reducing handover latency. Nodes include primary and secondary nodes. The primary node provides wireless access to the core network; the secondary node is not connected to the core network's control plane. The cells under the primary node are the primary cell group, and the cells under the secondary node are the secondary cell group. The cell with the best signal quality in the primary cell group is the primary cell, while the cell with the best signal quality in the secondary cell group is the primary and secondary cell.

[0120] The dual link is described below with reference to FIG4 .

[0121] Figure 4 is a schematic diagram of a dual link provided by an embodiment of the present application. As shown in Figure 4, the terminal device uses the wireless resources of the primary node and the secondary node. The primary cell group under the primary node includes the primary cell and the secondary cell, and the secondary cell group under the secondary node includes the primary and secondary cells and the secondary cell.

[0122] A feasible implementation method is to send relevant information of conditional switching, including: receiving a reporting indication and sending the relevant information according to the reporting indication; or, sending the relevant information when a preconfigured trigger condition is met; or, sending the relevant information according to a preset period.

[0123] The reporting indication is described below with reference to FIG5 .

[0124] Figure 5 is a schematic diagram of a reporting instruction provided by an embodiment of the present application. As shown in Figure 5, the network device sends a reporting instruction to the terminal device, instructing the terminal device to send relevant information through the reporting instruction. The terminal device responds to the reporting instruction and sends relevant information to the network device.

[0125] In combination with the scenario example, when the network device detects that the communication link of the terminal device is interrupted, or when the network device predicts that the communication link of the terminal device will be interrupted, or when the network device determines that the execution conditions are unreasonable, it sends a reporting instruction to the terminal device to instruct the terminal device to send relevant information and solve the problem of condition switching based on the relevant information. Through this instruction method, the terminal device can be flexibly instructed to send relevant information in real time, thereby improving the timeliness of processing. The pre-configured trigger conditions are stored in the terminal device, and when the terminal device meets the trigger conditions, the relevant information is sent. Through this method, the relevant information can be sent in a timely manner, reducing the sending delay. The terminal device sends relevant information according to the stored preset period. Through this method, the signaling overhead of the network device sending the reporting instruction can be reduced.

[0126] Optionally, the network device sends the trigger condition to the terminal device, or configures the trigger condition through a communication protocol.

[0127] Optionally, the network device predicts a preset period based on historical related information of the terminal device.

[0128] In this feasible implementation, the terminal device can be flexibly instructed to send relevant information through a variety of instruction methods.

[0129] In a feasible implementation manner, the triggering condition includes at least one of the following: the start duration of the second timer is greater than or equal to a preset threshold; a wireless link failure occurs.

[0130] Using a scenario example, if a wireless link failure occurs, it will severely impact the terminal device's communications. In this case, the terminal device immediately sends relevant information so that the network device can identify the problem based on the relevant information. On the other hand, if the terminal device successfully performs a handover and no link failure occurs, the target cell it switches to may not be the highest-quality cell. In this case, adjusting the target cell for handover can improve communication quality. The second timer can be used as a trigger condition to periodically send relevant information to the network device, effectively improving communication quality.

[0131] In a feasible implementation manner, the relevant information includes at least one of the following: configuration related information; condition related information of execution conditions, wherein the execution conditions include execution conditions of candidate primary cells and / or execution conditions of candidate primary and secondary cells; switching related information.

[0132] In this scenario example, a configuration can be defined for a network device or a communication protocol. A terminal device with this configuration can perform conditional switching. The terminal device configures the timing for conditional switching based on the execution condition and initiates the conditional switching when the execution condition is met. After each switch, the terminal device records the corresponding switch-related information.

[0133] Specifically, in a feasible implementation manner, configuration related information is used to indicate whether conditional switching with a candidate primary and secondary cell group has been configured for the terminal device.

[0134] Combined with the scenario example, on the premise that conditional switching with candidate primary and secondary cell groups has been configured for the terminal device, the terminal device can perform conditional switching with candidate primary and secondary cell groups.

[0135] Optionally, the manner of indicating configuration-related information includes but is not limited to at least one of the following: indicating configuration-related information through 1-bit signaling, through enumeration indication, or implicit indication, etc.

[0136] Exemplarily, if the 1-bit signaling includes "1", it indicates that conditional switching with a candidate primary and secondary cell group has been configured for the terminal device. If the 1-bit signaling includes "0", it indicates that conditional switching with a candidate primary and secondary cell group has not been configured. The enumeration indication may be that the terminal device sends a primary cell switching failure to the network device. The implicit indication may be that if the conditional switching is successfully executed, the corresponding execution condition is satisfied, or if the conditional switching fails, the corresponding execution condition is not satisfied.

[0137] In a feasible implementation method, the condition-related information includes at least one of the following: an execution condition, the execution condition including the execution condition related to the main cell and / or the execution condition related to the main and auxiliary cells; time-related information when the execution condition is met; and cell-related information when the execution condition is met.

[0138] In conjunction with the scenario example, for conditional switching with a candidate primary and secondary cell group, the terminal device needs to determine the execution condition related to the primary cell and / or the execution condition related to the primary and secondary cells to determine the time to execute the switch. The execution condition related to the primary cell and / or the execution condition related to the primary and secondary cells include specific judgment thresholds. The network device can determine whether the execution condition is reasonably configured based on the execution condition related to the primary cell and / or the execution condition related to the primary and secondary cells. Affected by factors such as terminal device movement or interference, the time when the execution condition is met or the cell in which the execution condition is met is variable.

[0139] Optionally, if the execution condition is unreasonable, the network device generates an optimized execution condition and sends the optimized execution condition to the terminal device.

[0140] In a feasible implementation, the time-related information includes at least one of the following:

[0141] The time or period when the execution condition of the candidate primary cell is met;

[0142] The time or period when the execution conditions of the candidate primary and secondary cells are met;

[0143] The duration for which the execution conditions of the candidate primary cell have been met;

[0144] The duration for which the execution conditions of the candidate primary and secondary cells have been met;

[0145] a time difference between when a first execution condition and a second execution condition are satisfied, where the first execution condition is an execution condition for the candidate primary cell and the second execution condition is an execution condition for the candidate primary and secondary cells;

[0146] Information on the order in which the first execution condition and the second execution condition are satisfied.

[0147] In combination with the scenario example, the network device can compare the execution conditions of the primary cell with the execution conditions of the primary and secondary cells based on whether the time or time period when the execution conditions are met matches, thereby determining whether the execution conditions are reasonable.

[0148] Exemplarily, the duration that the execution condition has been met is the duration between the moment the execution condition is met and the moment the link fails, the duration between the moment the execution condition is met and the moment the terminal device sends relevant information to the network device, or the duration between the moment the execution condition is met and the moment the execution condition switching is started.

[0149] Combined with the scenario example, if the execution condition has been met for a period exceeding the threshold, it means that the execution condition is reasonably configured. The network device determines whether the execution condition is reasonable based on the execution condition being met.

[0150] Illustratively, a larger value of the time difference between the first execution condition and the second execution condition being satisfied indicates that the threshold of one of the execution conditions is relatively high, and the matching between the first execution condition and the second execution condition is worse.

[0151] Exemplarily, the order information of satisfying the first execution condition and the second execution condition is that the first execution condition is satisfied first or the second execution condition is satisfied first.

[0152] Illustratively, the time difference between the first execution condition and the second execution condition being satisfied and the order in which the first execution condition and the second execution condition are satisfied may be implemented in combination.

[0153] Combined with the scenario example, the time difference between the first execution condition and the second execution condition being met, as well as the order in which the first execution condition and the second execution condition are met, can be used to determine whether the execution condition is reasonable. For example, if the first execution condition is met first and the second execution condition is met later, and the value of the time difference exceeds the numerical threshold, it is possible that although the execution condition switch is successful, the success rate of subsequent execution condition switches is low. This situation indicates that the threshold of the first execution condition is relatively easy to reach, while the threshold of the second execution condition is relatively difficult to reach. As a result, after the first execution condition is met, it still takes a long time to meet the second execution condition. The execution condition switch takes too long, indicating that the execution condition configuration is unreasonable.

[0154] In this feasible implementation, through various time information, it is possible to judge whether the execution conditions are reasonable from multiple dimensions, thereby improving the accuracy of the judgment.

[0155] In a feasible implementation method, the order information of satisfaction includes at least one of the following: relevant information of the first triggered execution condition; relevant information of the second triggered execution condition; a first identifier, wherein the first identifier is used to indicate that the moment when the first execution condition is satisfied is earlier than the moment when the second execution condition is satisfied, or the time period when the first execution condition is satisfied is earlier than the time period when the second execution condition is satisfied; a second identifier, wherein the second identifier is used to indicate that the moment when the first execution condition is satisfied is later than the moment when the second execution condition is satisfied, or the time period when the second execution condition is satisfied is later than the time period when the second execution condition is satisfied.

[0156] Exemplarily, the relevant information of the execution conditions includes but is not limited to at least one of the following: event index (event ID), event-related configuration (threshold, hysteresis, trigger time time to trigger), measurement index (measurement identity), cell-related information (cell index, cell type-primary cell or primary and secondary cell).

[0157] Using scenario examples, the first identifier corresponds to both time and time scenarios. For a time scenario, for example, the first execution condition is satisfied at 9:10, which is earlier than the second execution condition at 9:20. For a time scenario, for example, the first execution condition is satisfied between 9:00 and 9:59, while the second execution condition is satisfied between 10:00 and 10:59. This means that the first execution condition is satisfied earlier than the second. The second identifier applies to both time and time scenarios in a similar manner.

[0158] It can be understood that, through the relevant information of the execution condition, the event or cell corresponding to the execution condition can be accurately determined, as well as the specific content of the execution condition can be accurately determined.

[0159] For example, the order relationship of the time or time period of meeting the two execution conditions is determined by the first identifier and the second identifier. If the order information includes the first identifier, it means that the first execution condition is met first. If the order information includes the second identifier, it means that the second execution condition is met first.

[0160] In a feasible implementation manner, the cell-related information includes at least one of the following: first indication information, the first indication information is used to indicate whether the execution condition of the candidate primary cell is met, and / or whether the execution condition of the candidate primary and secondary cells is met; second indication information, the second indication information is used to indicate whether the execution condition of the candidate cell pair is met, the candidate cell pair includes a candidate primary cell and a candidate primary and secondary cell corresponding to the candidate primary cell, and the execution condition of the candidate cell pair includes the execution condition of the candidate primary cell and the execution condition of the candidate primary and secondary cells; cell pair information of the first candidate cell pair, wherein the execution condition of the candidate primary cell in the first candidate cell pair is met, and the execution condition of the candidate primary and secondary cells is not met sufficient; or, the execution condition of the candidate primary cell in the first candidate cell pair is not met, and the execution condition of the candidate primary and secondary cells is met; the primary cell information of the candidate primary cell whose execution condition is met, the primary cell information includes at least one of the following: the index of the candidate primary cell, or the execution condition of the candidate primary cell; the primary and secondary cell information of the candidate primary and secondary cells whose execution condition is met, the primary and secondary cell information includes at least one of the following: the index of the candidate primary and secondary cells, or the execution condition of the candidate primary and secondary cells; the execution condition of the candidate primary cell and the execution condition of the candidate primary and secondary cells in the second candidate cell pair, the execution conditions of the candidate primary cell and the candidate primary and secondary cells in the second candidate cell pair are respectively met; transmission configuration indication state TCI state related information.

[0161] Optionally, the indication method of the first indication information and the second indication information includes but is not limited to at least one of the following: indication through 1-bit signaling, indication through enumeration, or implicit indication, etc.

[0162] It should be noted that the indication method of the indication information refers to the indication method of the configuration related information, which will not be repeated here.

[0163] Exemplarily, the terminal device determines whether the execution conditions of the primary cell and the primary and secondary cells in the first indication information are satisfied respectively. The terminal device determines whether the execution conditions of the primary cell and the primary and secondary cells in the second indication information are satisfied simultaneously.

[0164] Illustratively, only one of the execution conditions of the candidate primary cell and the execution conditions of the candidate primary and secondary cells in the first candidate cell pair is satisfied, and both the execution conditions of the candidate primary cell and the execution conditions of the candidate primary and secondary cells in the first candidate cell pair are satisfied.

[0165] In conjunction with the scenario example, the network device optimizes the execution conditions based on the candidate cell pair information in the cell-related information. If the cell-related information includes the cell pair information of the first candidate cell pair, the unmet execution conditions are optimized, such as adjusting the threshold parameters in the execution conditions. If the cell-related information includes the cell pair information of the second candidate cell pair, indicating that the execution conditions of the candidate primary cell and the execution conditions of the candidate primary and secondary cells are both met, the execution conditions of the candidate primary cell and the execution conditions of the candidate primary and secondary cells are evaluated for matching, and the execution conditions are optimized based on the evaluation results to improve the reliability of the handover.

[0166] In this scenario example, cell information includes a cell index, allowing network devices to accurately identify the corresponding cell. Cell information also includes execution conditions, allowing network devices to quickly obtain these conditions, improving execution efficiency.

[0167] Optionally, a Transmission Configuration Indicator state (TCI state) may be provided. The TCI state may include, but is not limited to, one of the following: TCI state, TCI state index, or activation status. The network device may select the optimal transmission beam based on the TCI state, thereby optimizing data transmission reliability. Using the information regarding whether the TCI state is activated, the network device may determine whether downlink synchronization with the target cell has been achieved or whether a neighboring cell has an activated TCI state.

[0168] In a feasible implementation method, the cell pair information includes at least one of the following items: the index and / or execution condition of the cell whose execution condition is met in the first candidate cell pair; the index and / or execution condition of the cell whose execution condition is not met in the first candidate cell pair.

[0169] In this example scenario, the execution conditions for one candidate cell are met for the first candidate cell, but not for the other candidate cell. Recording this information in the cell-related information is valuable for network optimization and troubleshooting. Specifically, by analyzing which cells meet and do not meet the execution conditions, network equipment can better understand network performance and coverage, thereby optimizing network configuration, adjusting handover parameters, or resolving potential network issues.

[0170] In a feasible implementation method, the switching related information includes at least one of the following: a switching result, the switching result is used to indicate that the switching is successful or failed; an index of the candidate primary cell and an index of the candidate primary and secondary cells in the second candidate cell pair, and the execution conditions of the candidate primary cell and the candidate primary and secondary cells in the second candidate cell pair are respectively met; a measurement result, the measurement result includes at least one of the following: a measurement result of a serving cell, a measurement result of a neighboring cell, or a measurement result of a candidate cell; timer information of a first timer, the timer information includes at least one of the following: a remaining duration of the first timer, a running duration of the first timer, and a ratio of the remaining duration to the total duration of the first timer.

[0171] Among them, if after the handover is executed, the terminal device can receive the signal of the target cell and communicate, the handover result is a successful handover, otherwise it is a failed handover. The cell index can be used to accurately distinguish the cells, avoid cell confusion, and improve the accuracy of solving the problem of conditional handover. The measurement results include but are not limited to at least one of the following: signal quality, interference level, signal coverage, or signal strength, etc. The total duration of the first timer in the timer information is the duration used for the handover. The timing starts when the terminal device starts to execute the handover and stops when the terminal device completes the handover. The duration between the start time and the stop time is the elapsed time, and the difference between the total time and the elapsed time is the remaining time.

[0172] Combined with the scenario example, network equipment can evaluate the communication quality of terminal devices from multiple dimensions based on various measurement results, thereby improving the accuracy of solving conditional switching problems.

[0173] Optionally, the switching is executed by controlling the total duration of the first timer. If the duration of the switching exceeds the total duration of the first timer, the switching is stopped and the switching result is determined to be a switching failure.

[0174] Optionally, the total duration of the first timer is optimized based on the remaining duration of the first timer or the running duration of the first timer. For example, if the handover result is a successful handover and the running duration of the first timer is longer or the remaining duration of the first timer is shorter, the first timer is reconfigured.

[0175] In this scenario example, the network device can determine the ease of executing a handover based on timer information. The shorter the elapsed time of the first timer or the longer the remaining time of the first timer, the easier it is to execute a handover, achieving a seamless handover. Controlling handover execution by the total duration of the first timer can avoid communication interruptions caused by continuous handover execution.

[0176] Optionally, the time corresponding to the switching result is recorded in the switching related information.

[0177] Optionally, if the handover fails, the specific reason for the failure is recorded, such as signal quality issues or insufficient resources in the target cell.

[0178] In a feasible implementation method, the information transmission method also includes: sending device capabilities of the terminal device, the device capabilities including a first capability and / or a second capability, wherein the first capability is used to indicate the ability of the terminal device to report link failure under the conditional switching scenario; the second capability is used to indicate the ability of the terminal device to report switching results under the conditional switching scenario.

[0179] Combined with the scenario example, when the terminal device reports the link status, the network device can clearly know the status of the link corresponding to the terminal device, thereby quickly resolving the problem of conditional switching. Before the terminal device reports the relevant information of the conditional switching, it reports the first capability. The network device determines that it is not necessary for the network device to obtain the link status based on the first capability, which can reduce the operation of the network device. When the terminal device reports the switching result, the network device can clearly know the switching result corresponding to the terminal device, thereby quickly resolving the problem of conditional switching. Before the terminal device reports the relevant information of the conditional switching, it reports the second capability. The network device determines that it is not necessary for the network device to obtain the switching result based on the second capability, which can reduce the operation of the network device.

[0180] A feasible implementation manner is to record the relevant information according to the first configuration information and / or predefined information.

[0181] Optionally, the first configuration information is a network device indication, and the predefined information is pre-configured by the terminal device. The terminal device determines the time to record the relevant information according to the first configuration information and / or the predefined information.

[0182] Specifically, in a feasible implementation, the first configuration includes at least one of the following: a recording period; a recording start time; a recording end time; and timer information of the second timer.

[0183] In conjunction with the scenario example, the terminal device records the relevant information once every recording period. The terminal device begins recording the relevant information at the start time of recording. The terminal device ends recording the relevant information at the end time of recording. The terminal device begins recording the relevant information after receiving the first configuration information and after the duration corresponding to the second timer.

[0184] A feasible implementation method, the predefined information is used to indicate at least one of the following: recording the relevant information between receiving the first configuration information and receiving the reporting indication, the reporting indication is used to instruct the terminal device to send the relevant information; recording the relevant information between receiving two adjacent reporting indications.

[0185] Next, the recording of relevant information will be described with reference to FIG6 a for the solution of the first configuration information.

[0186] Figure 6a is a schematic diagram of recording relevant information provided by an embodiment of the present application. As shown in Figure 6a, the network device sends first configuration information, which indicates to the terminal device the time to execute recording relevant information through the first configuration information. The terminal device begins recording relevant information in response to the first configuration information. The terminal device sends the recorded relevant information until it receives the reporting instruction sent by the network device.

[0187] Next, for a solution that does not include the first configuration information, recording related information will be described with reference to FIG6 b .

[0188] Figure 6b is a schematic diagram of recording relevant information according to an embodiment of the present application. As shown in Figure 6b, according to the configuration of the terminal device, the terminal device records relevant information. In response to the current reporting instruction sent by the network device, the terminal device sends the previous set of recorded relevant information and records the current relevant information until a subsequent reporting instruction is received, at which point the terminal device sends the current relevant information.

[0189] In a feasible implementation manner, the information transmission method further includes: sending third indication information, where the third indication information is used to indicate whether the relevant information exists in the terminal device.

[0190] The third indication information is described below with reference to FIG. 7 .

[0191] Figure 7 is a schematic diagram of the third indication information provided in an embodiment of the present application. As shown in Figure 7, the terminal device sends the third indication information to the network device, and the network device determines whether the terminal device has relevant information based on the third indication information. If the terminal device has relevant information, the network device sends a reporting instruction to the terminal device.

[0192] In this feasible implementation, the network device can determine whether the terminal device has relevant information through the third indication information. When the terminal device does not have relevant information, the network device sends a reporting indication, resulting in a waste of signaling resources.

[0193] A feasible implementation method of sending the third indication information includes: sending a first message, the first message including the third indication information; wherein, the first message includes at least one of the following: a radio resource control RRC setting completion message, an RRC reconfiguration completion message, and an RRC recovery completion message.

[0194] In conjunction with the scenario example, during the initial access process, when the terminal device establishes an initial radio resource control connection with the network device, after the terminal device successfully completes the RRC connection setup process, it sends an RRC setup completion message to notify the network device. When the network device needs to modify the radio resource configuration of the terminal (for example, changing the service cell, adjusting transmission parameters, etc.), it will send an RRC reconfiguration message to the terminal device. After the terminal device successfully applies the configuration change, it sends an RRC reconfiguration completion message to the network device to confirm that the change has been completed. When the UE enters a low power state (a low power state) and needs to be restored to an active state later, the network device will send an RRC recovery message to wake up the terminal device. After the terminal device completes the recovery process, it sends an RRC recovery completion message to notify the network device that data transmission can be performed.

[0195] In this feasible implementation, the third indication information can be flexibly sent through various forms of the first message.

[0196] The information transmission method according to the embodiment of the present application has been described above.
