Description

Information reporting method, device and storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on March 15, 2024, with application number 202410307035.3 and application name “Information Reporting Method, Device and Storage Medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] In the field of communications technology, Layer 1 / Layer 2 triggered mobility management (LTM) technology is used to perform cell handovers and ensure communication continuity for terminal devices. LTM technology pre-configures multiple candidate cells based on information such as the terminal device's current location, movement speed, direction, and network topology. These candidate cells serve as handover targets for the terminal device, ensuring that the terminal device can seamlessly switch to the optimal serving cell during mobility.

[0004] After receiving the handover instruction, the terminal device will execute the handover operation according to the instruction. This includes establishing synchronization with the target cell, completing resource allocation, and completing signaling exchanges. After the handover is completed, the terminal device will transmit data through the target cell.

[0005] However, the target cell may not be the cell with the best communication quality, resulting in poor communication quality of the terminal device. Summary of the Invention

In addition, the terminal device may also be an on-board module, on-board module, on-board component, on-board chip or on-board unit built into the vehicle as one or more components or units, and the vehicle may implement the method provided in the present application through the built-in on-board module, on-board module, on-board component, on-board chip or on-board unit. Therefore, the embodiment of the present application may also be applied to the Internet of Vehicles, such as vehicle to everything (V2X), long term evolution-vehicle (LTE-V), vehicle-to-vehicle (V2V) technology, etc.

[0113] 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.

[0114] As a terminal device moves within a wireless communication network, its physical and network layers monitor changes in communication quality with surrounding network devices. When this change reaches a certain threshold or condition, mobility management processes, such as cell handover, are triggered. This triggering of mobility management optimizes the terminal device's communication quality and ensures normal communication with network devices.

[0115] Figure 2 is a schematic diagram of reporting related information provided by an embodiment of the present application. As shown in Figure 2, the network device preconfigures multiple candidate cells, the terminal device reports the current layer 1 measurement results, the network device determines the target cell based on the layer 1 measurement results, and the network device sends a handover instruction to the terminal device to switch the terminal device to the target cell.

[0116] In actual applications, due to unreasonable terminal device configuration or unreasonable network signaling configuration, cell switching failure may occur, or although the switching is successful, the communication quality of the target cell to which the terminal device switches is poor, which in turn leads to poor communication quality of the terminal device.

[0117] 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.

[0118] FIG3 is a flow chart of an information reporting method provided in an embodiment of the present application. As shown in FIG3 , the information reporting method includes:

[0119] S301: Send first layer 1 / layer 2 triggered mobility management LTM related information, where the first LTM related information includes related information recorded in the LTM process.

[0120] The first LTM related information corresponds to a recorded moment, and the first LTM related information is the LTM related information corresponding to a recorded moment closest to the preset moment.

[0121] For example, the relevant information recorded during the LTM process can reflect the location status of the terminal device, the communication status of the terminal device, or the relevant parameters of the terminal device performing switching. The network device analyzes the relevant information recorded during the LTM process to help optimize network performance, improve user service quality, and perform troubleshooting.

[0122] A feasible implementation method, the first LTM related information includes at least one of the following: the index of the target cell; the index of the target beam; the timing advance TA related information; the measurement result; whether the uplink synchronization is completed; the random access related information; whether the downlink synchronization is completed; whether the target beam or the transmission configuration indication TCI is activated; the time difference between sending uplink data and receiving downlink scheduling; the remaining duration of the first timer.

[0123] The target cell index is used to identify the target cell, which is the cell to which the terminal device switches. Based on the target cell index, the network device can accurately determine the cell to which the terminal device switches. The target beam index is used to identify the target beam, which is the beam received by the terminal device. Based on the target beam index, the network device can accurately determine the beam used for communication by the terminal device. Timing Advance (TA) related information is used to adjust the timing of uplink transmission to ensure that user devices from different locations can reach the base station synchronously. Uplink synchronization is maintained and signal interference is avoided based on the timing advance (TA) related information. Measurement results include but are not limited to signal strength, signal-to-noise ratio, interference level, etc. The measurement results reflect network performance, and the network device performs network optimization based on the measurement results. Whether uplink synchronization is completed indicates whether the terminal device has successfully synchronized its uplink transmission with the network. Uplink synchronization is a basic requirement in wireless communications. Whether uplink synchronization is completed ensures that data is effectively transmitted. The random access process is used by the terminal device to establish an initial connection or re-establish a connection with the network device. Based on the random access process information, the network device can determine and manage the access process of the terminal device. Whether the downlink synchronization is completed indicates whether the terminal device has successfully synchronized its downlink reception with the network device. Downlink synchronization is a prerequisite for the device to correctly receive network data. Whether the downlink synchronization is completed ensures that the data is effectively transmitted. Transmission Configuration Indication (TCI) TCI is used to instruct the terminal device how to configure its uplink and / or downlink transmission. The network device determines whether the data is accurately transmitted based on whether the target beam is activated or the transmission configuration indication TCI. The time difference between sending uplink data and receiving downlink scheduling reflects the scheduling delay of the network device. The network device evaluates network performance and performs network optimization based on the time difference. The first timer starts when the terminal device sends the first uplink and ends when the downlink scheduling is received. According to the remaining time of the first timer and the time difference between sending uplink data and receiving downlink scheduling, it can be determined whether the downlink scheduling is too late or the downlink synchronization instruction is issued too late.

[0124] For example, if the downlink synchronization is not completed or the transmission configuration indication is not activated, it may be that the instruction for activating the transmission configuration is sent too late by the network device.

[0125] In a feasible implementation method, the timing advance TA related information includes at least one of the following: TAT value and / or TA group index TAG ID; TAT remaining value; TAT remaining value ratio; TAT running value; TAT running value ratio; whether it is a TA based on terminal device measurement.

[0126] The TAT value is a specific timing advance value used to compensate for time deviations caused by signal transmission delays. The TA group index TAG ID is a unique identifier for grouping TA values. Based on the TA group index TAG ID, timing advance (TA) related information can be effectively managed, resource allocation can be optimized, and signaling overhead can be reduced. The TAT remaining value is the unused portion of the current TAT value. The TAT remaining value percentage is the percentage of the used portion of the current TAT value to the TAT value. The TAT run value is the used portion of the current TAT value. The TAT run value is the used portion of the current TAT value to the TAT value. The network device determines the source of the TA based on whether it is a TA measured by the terminal device.

[0127] Next, timing advance TA related information will be described with reference to FIG. 4 .

[0128] Figure 4 is a schematic diagram of timing advance (TA)-related information provided in an embodiment of the present application. As shown in Figure 4, timing begins after the terminal device measures the TA and stops when the terminal device switches. The duration between the start and stop of timing is the TAT elapsed value, and the ratio of the TAT elapsed value to the TAT value is the TAT elapsed value percentage. The difference between the TAT value and the TAT elapsed value is the TAT remaining value, and the ratio of the TAT remaining value to the TAT value is the TAT remaining value percentage.

[0129] In combination with a scenario example, if the TAT value is 10s and the time between start and stop is 8s, the TAT running value is 8s, the TAT running value accounts for 80%, and the TAT remaining value is 2s, and the TAT remaining value accounts for 20%.

[0130] Exemplarily, the network device optimizes based on timing advance (TA)-related information. If the TAT remaining value in the timing advance (TA)-related information measured by the terminal device accounts for a large proportion, but random access is not completed, there is a problem with the terminal device measurement, which may be a terminal device failure or terminal device measurement error. Subsequently, terminal device measurement-based configuration will no longer be configured. If the TAT remaining value accounts for a small proportion, but random access is successful, the duration corresponding to the TAT can be subsequently increased to reduce the frequency of terminal device measurement and TA calculation.

[0131] For example, if the following situations exist: the TAT running value is too large, the TAT running value ratio is too large, the TAT remaining value is too small, or the TAT remaining value ratio is too small, it can be determined that the downlink scheduling after access is too late or the downlink synchronization instruction is issued too late.

[0132] In a feasible implementation method, the random access related information includes at least one of the following: an access type, the access type includes at least one of the following: random access channel access RACH-less, contention-based random access CBRA, non-contention-based random access CFRA, or an access type indicated by a network device; random access execution related information, the execution related information includes at least one of the following: preamble code transmission signaling MSG1, two-step random access message MSGA, the correspondence between beams and cells, TCI status index, or a fallback mechanism based on random access.

[0133] Random access is a key process in wireless communication systems, allowing terminal devices to establish an initial connection or reestablish a connection with network devices. The access type determines the specific method and conditions for random access. RACH-less access refers to access performed without using a traditional random access channel. Contention-based random access (CBRA) allows multiple terminal devices to use the same resources to transmit preambles, resolving potential conflicts in subsequent steps. Contention-free random access (CFRA) allocates dedicated preamble resources to specific terminal devices, avoiding contention and conflicts. The access type indicated by the network device instructs the terminal device to use a specific access type based on network conditions and requirements. Random access execution-related information provides details about the actual execution of the random access process. Preamble transmission signaling (MSG1) is the first step in the random access process, initiated by the terminal device by sending a preamble. The two-step random access message (MSGA) is a simplified random access process in which MSG1 and MSG3 are combined into a single message, reducing transmission latency. The correspondence between beams and cells is used to determine the optimal communication path between the terminal device and network equipment. The Transmission Configuration Indicator (TCI) state index indicates the beam or transmission path used by the terminal device for data transmission. The random access-based fallback mechanism is a fault-tolerant mechanism. When the random access process fails, the terminal device can fall back and try again according to a predetermined strategy.

[0134] Using scenario examples, in millimeter wave communication systems, a cell is typically composed of an area covered by multiple beams. On the one hand, each beam corresponds to a specific transmission direction and establishes a communication link with one or more terminal devices. Through the correspondence between beams and cells, network equipment can accurately determine the location of each terminal device and the optimal communication direction. In this way, the network equipment can select the optimal beam to communicate with the terminal device, thereby avoiding signal interference and path loss, and improving communication quality and efficiency. On the other hand, based on the correspondence between beams and cells, network equipment can achieve fast and reliable beam switching and beam management. When the terminal device moves within the cell, the network equipment can dynamically adjust the direction of the beam according to the terminal's location and movement trajectory to ensure that the terminal device always maintains a connection with the optimal beam. This helps reduce communication interruptions and delays and improve user experience.

[0135] For example, in RACH-less access, the transmission configuration indication TCI state index is used to indicate which beam or transmission path the terminal device should use when receiving the physical downlink shared channel (PDSCH), ensuring that the terminal device can correctly receive downlink data. RACH-less access is not applicable to all situations. For example, when the terminal device cannot find a matching beam and cell correspondence, or when the network device determines that using a RACH-based access method is more reliable, the terminal device needs to fall back to the traditional RACH-based access method. The fallback mechanism improves the flexibility and reliability of communication.

[0136] It can be understood that through a variety of random access related information, the network device can analyze the problems existing in the terminal device from multiple dimensions, thereby accurately optimizing the communication quality of the terminal device.

[0137] In a feasible implementation manner, the measurement result is a downlink measurement result when the TA is acquired, or a difference between the downlink measurement result and a result of the most recent measurement when the handover fails.

[0138] Optionally, the TA is obtained from a Media Access Control Control Element (MAC CE for short).

[0139] For example, the downlink measurement result when obtaining TA reflects the signal status between the terminal device and the network device when establishing or maintaining uplink synchronization. This measurement result usually includes parameters such as signal strength and signal-to-noise ratio, which are used to evaluate the communication quality of the downlink. Through the downlink measurement results, the network device can determine whether the TA value needs to be adjusted to compensate for the transmission delay caused by terminal movement or environmental changes. The difference between the downlink result of the most recent measurement when the switching fails and the measurement result when the TA is obtained provides information about the change in network status. This difference reflects the change in signal quality caused by factors such as terminal device movement, interference changes, or network configuration adjustments during the switching process. If this difference is large, it means that a problem has been encountered during the switching process and the switching solution needs to be optimized.

[0140] For example, based on the measurement results, the network equipment can perform the following operations and optimizations: TA adjustment: Based on the downlink measurement results when obtaining TA, the TA value can be accurately adjusted to ensure the accuracy of uplink synchronization. Switching optimization: By analyzing the measurement difference when the switching fails, the possible causes of the switching failure can be identified, such as insufficient signal coverage, excessive interference, or improper network configuration. For these problems, the network can take corresponding optimization measures, such as adjusting the power of network equipment, optimizing frequency resource configuration, or improving the switching algorithm. Performance monitoring and early warning: Continuously monitoring the changing trends of downlink measurement results and measurement differences can timely identify potential performance problems and issue early warnings, so that preventive measures can be taken in advance to avoid network failures or performance degradation.

[0141] In a feasible implementation manner, the information reporting method further includes: receiving first information, where the first information is used to instruct the terminal device to send first LTM-related information.

[0142] Next, the first information will be described with reference to FIG5 .

[0143] Figure 5 is a schematic diagram of the first information provided by an embodiment of the present application. As shown in Figure 5, the network device sends the first information to the terminal device, and the terminal device sends the first LTM related information in response to the first information.

[0144] A feasible implementation method, before receiving the first information, further includes: receiving a measurement configuration, where the measurement configuration is used to instruct the terminal device to record the first LTM related information.

[0145] The measurement configuration is described below with reference to FIG6 .

[0146] Figure 6 is a schematic diagram of a measurement configuration provided in an embodiment of the present application. As shown in Figure 6, the network device sends the measurement configuration to the terminal device, the terminal device records the first LTM-related information in response to the measurement configuration, the network device sends the first information to the terminal device, and the terminal device sends the first LTM-related information in response to the first information.

[0147] In this scenario example, some terminal devices do not record LTM-related information. If a network device sends a first message to the terminal device, the terminal device cannot report the information because it does not record LTM-related information. By sending a measurement configuration to the terminal device, instructing the terminal device to record the first LTM-related information, the terminal device can ensure that it can send the first LTM-related information in response to the first message, thereby improving the reliability of information reporting.

[0148] Optionally, before receiving the measurement configuration, the step further includes sending capability information to the network device.

[0149] Exemplarily, the capability information indicates whether the terminal device has the capability to record LTM-related information, and the network device sends the measurement configuration according to the capability information.

[0150] In this scenario example, if the terminal device has the capability to record LTM-related information, the network device sends a measurement configuration to instruct the terminal device to perform measurements. If the terminal device does not have the capability to record LTM-related information, even if the network device sends the measurement configuration, the terminal device cannot perform measurements. Sending the measurement configuration in this case increases signaling overhead.

[0151] A feasible implementation method, before receiving the first information, further includes: sending second information, where the second information is used to instruct the network device that the terminal device stores the first LTM related information.

[0152] Combined with the scenario example, the network device can determine that the terminal device has obtained and stored the first LTM related information through recording based on the second information. On this basis, the network device sends the first information to ensure that the terminal device sends the first LTM related information in response to the first information.

[0153] Optionally, the measurement configuration and the second information schemes may be implemented in combination or one of the schemes may be implemented.

[0154] The measurement configuration and the second information are described below with reference to FIG7 .

[0155] Figure 7 is a schematic diagram of a measurement configuration and second information provided in an embodiment of the present application. As shown in Figure 7, a network device sends a measurement configuration to a terminal device, and the terminal device records first LTM-related information in response to the measurement configuration. After recording the first LTM-related information, the terminal device sends second information to the network device. Based on the second information, the network device determines that the terminal device currently stores the first LTM-related information. The network device sends the first information to the terminal device, and the terminal device sends the first LTM-related information in response to the first information.

[0156] In this feasible implementation, the reliability of the first information is improved by the second information, thereby improving the reliability of information reporting.

[0157] In a feasible implementation method, the first information includes at least one of the following: a first sending indication, the first sending indication is used to instruct the terminal device to send the first LTM related information; a second sending indication, the second sending indication is used to instruct the terminal device to send the first LTM related information according to a predefined rule; and a reporting trigger condition.

[0158] Among them, the first sending indication is used to instruct the terminal device to immediately send the first LTM related information, the second sending indication is used to instruct the terminal device to determine the time to send the first LTM related information according to predefined rules, and the reported trigger condition is used to instruct the terminal device to determine the time to send the first LTM related information according to the trigger condition.

[0159] In combination with the scenario example, the terminal device determines the trigger condition based on the first information, and the terminal device determines in real time whether the trigger condition is met. When the trigger condition is met, the terminal device sends the first LTM related information.

[0160] In a feasible implementation manner, the triggering condition for reporting includes at least one of the following: period information; a second timer; and a timing advance TA-related threshold.

[0161] The periodic information is used to instruct the terminal device to periodically transmit the first LTM-related information, i.e., the terminal device transmits the first LTM-related information once every preset duration. The second timer is used to instruct the terminal device to delay transmitting the first LTM-related information for a preset duration. The timing advance threshold (TA) is used to instruct the terminal device to transmit the first LTM-related information when the relevant threshold is met.

[0162] Next, a solution in which a terminal device receives first information and sends first LTM-related information is described through multiple embodiments.

[0163] Embodiment 1: The first information includes a first sending instruction.

[0164] In a feasible implementation manner, the first information includes the first sending instruction; sending the first LTM related information includes: receiving the first sending instruction, and sending the first LTM related information.

[0165] Next, the information related to sending the first LTM provided in the first embodiment of the present invention will be described with reference to FIG8 .

[0166] Figure 8 is a schematic diagram of sending first LTM related information provided by an embodiment of the present application. As shown in Figure 8, the network device sends a first sending indication to the terminal device, and the terminal device responds to the first sending indication and sends the first LTM related information to the network device at the moment of receiving the first sending indication.

[0167] In related technologies, for continuously triggered mobility management, such as when frequent terminal device movement or network coverage issues lead to continuous cell handovers, each triggered mobility management process records relevant information about the corresponding mobility management process, and the terminal device continuously reports relevant information about the mobility management process. Continuously reporting relevant information about mobility management results in high signaling overhead, which in turn wastes network resources and affects network data transmission.

[0168] In conjunction with the scenario example, the network device detects the communication quality of the terminal device and sends a first sending indication according to the communication quality to control the amount of LTM-related information sent, thereby reducing signaling overhead.

[0169] Embodiment 2: The first information includes a second sending instruction.

[0170] A feasible implementation method is that the first information includes the second sending indication; sending the first LTM related information includes: receiving the second sending indication, determining a predefined rule, the predefined rule including the first time length between receiving the first information and sending the first LTM related information, and / or the period for sending the first LTM related information; sending the first LTM related information according to the second sending indication.

[0171] Next, the information related to sending the first LTM provided in the second embodiment of the present invention will be described with reference to FIG. 9 .

[0172] Figure 9 is a schematic diagram of sending first LTM related information provided by an embodiment of the present application. As shown in Figure 9, the network device sends a second sending indication to the terminal device to instruct the terminal device to send the first LTM related information according to the predefined rules. The terminal device responds to the second sending indication, determines the predefined rules, and sends the first LTM related information according to the predefined rules.

[0173] In conjunction with the scenario example, if the predefined rule includes a first duration between receiving the first information and sending the first LTM-related information, the terminal device sends the first LTM-related information after the first duration has elapsed from the moment the second sending instruction is received. If the predefined rule includes a period for sending the first LTM-related information, the terminal device sends the first LTM-related information once every such period. If the predefined rule includes a first duration and a period for sending the first LTM-related information, the terminal device sends the first LTM-related information once every such period after the first duration has elapsed from the moment the second sending instruction is received.

[0174] In a feasible implementation manner, the terminal device pre-stores the predefined rules, or pre-defines the predefined rules through a communication protocol.

[0175] In combination with the scenario example, if the network device determines that the terminal device has stored predefined rules, or the network device determines that the communication protocol has defined predefined rules, the second sending indication can be used to instruct the terminal device to send the first LTM related information according to the predefined rules.

[0176] Optionally, the terminal device sends a notification to the network device, so that the network device determines that the terminal device has stored the predefined rule, or the communication protocol has defined the predefined rule.

[0177] In this feasible implementation, the first LTM related information is sent according to predefined rules, and the network device does not need to determine the reporting time or reporting cycle, which can improve the efficiency of information reporting.

[0178] Embodiment 3: The first information includes period information.

[0179] A feasible implementation method of sending the first LTM related information includes: receiving the period information, and sending the first LTM related information every period duration corresponding to the period information.

[0180] Next, the information related to sending the first LTM provided in the third embodiment of the present invention will be described with reference to FIG10 .

[0181] Figure 10 is a schematic diagram of sending first LTM related information provided by an embodiment of the present application. As shown in Figure 10, the network device sends periodic information to the terminal device, and the terminal device responds to the periodic information and determines the duration corresponding to the periodic information. The terminal device sends the first LTM related information every periodic duration.

[0182] 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.

[0183] 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 third timer; the cycle duration is the duration corresponding to the third timer.

[0184] 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-related information at 10:10, 10:20, 10:30, etc. If the cycle information includes a third timer, the duration corresponding to the third 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 to obtain multiple cycles.

[0185] In this feasible implementation, by determining a variety of cycles, it can be applied to a variety of application scenarios, thereby improving the versatility of information reporting.

[0186] Embodiment 4: The first information includes a second timer.

[0187] A feasible implementation method is to send the first LTM related information, including: receiving the second timer, and sending the first LTM related information after the duration corresponding to the second timer has elapsed.

[0188] Next, the information related to sending the first LTM provided in the fourth embodiment of the present invention will be described with reference to FIG11 .

[0189] Figure 11 is a schematic diagram of sending first LTM related information provided in an embodiment of the present application. As shown in Figure 11, the network device sends a second timer to the terminal device, the terminal device responds to the second timer, determines the duration corresponding to the second timer, and the terminal device sends the first LTM related information after the duration corresponding to the second timer has passed.

[0190] Combined with the scenario example, the network device predicts that the communication quality of the terminal device will change in the future, and then instructs the terminal to delay sending the first LTM related information through the second timer. The delayed sending of the first LTM related information can reflect the communication quality of the terminal device at the predicted future moment, so as to accurately perform corresponding optimization based on the communication quality.

[0191] Embodiment 5: The first information includes a threshold value of a timing advance TA-related value.

[0192] A feasible implementation method is to send the first LTM related information, including: receiving a threshold of the related value, and sending the first LTM related information if the timing advance TA related value of the terminal device exceeds the threshold of the related value.

[0193] Next, the information related to sending the first LTM provided in the fifth embodiment of the present invention will be described with reference to FIG12 .

[0194] Figure 12 is a schematic diagram of sending first LTM related information provided by an embodiment of the present application. As shown in Figure 12, the network device sends a threshold value of a timing advance TA related value to the terminal device. The terminal device responds to the threshold value of the timing advance TA related value and determines whether the timing advance TA related value of the terminal device exceeds the threshold value of the related value. If it exceeds, the first LTM related information is sent.

[0195] Combined with the scenario example, the network device determines the threshold of the timing advance TA related value based on the communication quality threshold. If the timing advance TA related value of the terminal device exceeds the threshold of the related value, it means that the communication quality of the terminal device does not meet the communication requirements, and the first LTM related information is sent to enable the network device to optimize the communication quality of the terminal device.

[0196] In this feasible implementation, the time of sending the first LTM-related information can be accurately determined by the threshold of the relevant numerical value, which can effectively reduce the signaling overhead compared to the terminal device sending the LTM-related information for each switching trigger.

[0197] The information reporting method of the embodiment of the present application has been described above. The following describes the device for performing the above-mentioned information reporting method provided in the embodiment of the present application. Those skilled in the art will understand that the method and device can be combined and referenced with each other, and the relevant device provided in the embodiment of the present application can perform the steps in the above-mentioned list sorting method.

[0198] FIG13 is a schematic diagram of the structure of the information reporting device provided in an embodiment of the present application. As shown in FIG13 , the information reporting device 130 includes:

[0199] The first sending module 131 is configured to send first layer 1 / layer 2 triggered mobility management LTM related information, where the first LTM related information includes related information recorded in the LTM process.

[0200] In one possible embodiment, the first LTM-related information includes at least one of the following: the index of the target cell; the index of the target beam; the timing advance TA-related information; the measurement result; whether the uplink synchronization is completed; the random access-related information; whether the downlink synchronization is completed; whether the target beam or the transmission configuration indication TCI is activated; the time difference between sending uplink data and receiving downlink scheduling; and the remaining duration of the first timer.

[0201] In a possible implementation, the timing advance TA related information includes at least one of the following: TAT value and / or TA group index TAG ID; TAT remaining value; TAT remaining value ratio; TAT running value; TAT running value ratio; whether it is a TA based on terminal device measurement.

[0202] In a possible implementation, the random access related information includes at least one of the following: an access type, the access type including at least one of the following: random access channel access RACH-less, contention-based random access CBRA, non-contention-based random access CFRA, or an access type indicated by a network device; random access execution related information, the execution related information including at least one of the following: preamble transmission signaling MSG1, two-step random access message MSGA, the correspondence between beams and cells, a TCI state index, or a fallback mechanism based on random access.

[0203] In a possible implementation manner, the measurement result is a downlink measurement result when the TA is acquired, or a difference between the downlink measurement result and a result of the most recent measurement when the handover fails.

[0204] In a possible implementation, the apparatus further includes: a first receiving module 132, configured to receive first information, where the first information is used to instruct the terminal device to send first LTM-related information.

[0205] In a possible implementation, the first information includes at least one of the following: a first sending indication, the first sending indication is used to instruct the terminal device to send the first LTM related information; a second sending indication, the second sending indication is used to instruct the terminal device to send the first LTM related information according to a predefined rule; and a reporting trigger condition.
