Description

A communication method, communication device and storage medium

[0001] This application claims priority to Chinese Patent Application No. 202411844231.0, filed on December 12, 2024, entitled "A Communication Method, Communication Device and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method, communication device and storage medium. Background Technology

[0003] Low-Latency Triggered Mobility (LTM) aims to improve network performance and user experience by optimizing mobility management mechanisms. LTM implements Layer 1 (L1) measurement and handover, primarily supporting handover between different cells for terminal devices. By reducing data interruptions during handover, it enables the network to respond to UE mobility needs more quickly and accurately, thereby ensuring service continuity and stability. Currently, when terminal devices perform cell handover based on the LTM mechanism, network performance needs to be measured based on LTM measurement events to evaluate and optimize user equipment mobility performance. LTM measurement events aim to trigger mobility decisions through low-layer measurements, thereby reducing mobility latency and improving network performance.

[0004] However, when terminal devices perform measurements based on LTM measurement events, they need to engage in multiple signaling interactions with the Layer 3 (L3) layer of the network device, resulting in high mobility latency for the terminal devices. Summary of the Invention

[0005] This application provides a communication method, communication device, and storage medium, with the aim of reducing the mobility latency of terminal devices.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A first aspect of this application provides a communication method applied to a terminal device, the method comprising:

[0008] Receives a Radio Resource Control (RRC) reconfiguration message, the RRC reconfiguration message including multiple measurable events of the terminal device;

[0009] A measurement is performed based on the first measurement event in the events to be measured, and a first measurement report of the first measurement event is obtained;

[0010] If the first measurement report meets the reporting conditions for the first measurement event, the first measurement report is sent.

[0011] In the above implementation scheme, the network device can configure multiple measurand events that the terminal device needs to measure at one time. The terminal device can determine the first measurand event to be measured from the multiple measurand events as needed. When measuring again, it can also directly determine the next measurand event to be measured based on the multiple measurand events previously acquired, without the need for the network device's Layer 3 to configure the next measurand event to be measured through signaling. This reduces the number of interactions between the network device's Layer 3 and the terminal device, thereby reducing the mobility latency of the terminal device.

[0012] In one possible implementation of the first aspect of this application, the RRC reconfiguration message further includes first indication information, which is used to indicate the measurement order of the events to be measured. In the above implementation, the RRC reconfiguration message sent by the network device to the terminal device may also carry the first indication information for indicating the measurement order of the events to be measured. That is, the network device can also configure the measurement order of each event to be measured to the terminal device, so that the terminal device can determine the first measurement event from the events to be measured based on the first indication information, thereby reducing the number of interactions between the layer 3 network device and the terminal device, and thus reducing the mobility latency of the terminal device.

[0013] In one possible implementation of the first aspect of this application, the first indication information includes first indication sub-information and second indication sub-information. The first indication sub-information is used to indicate the start condition of the event to be measured, and the second indication sub-information is used to indicate the stop condition of the event to be measured. In the above implementation, the first indication information can be composed of first indication sub-information for indicating the start condition of the event to be measured and second indication sub-information for indicating the stop condition of the event to be measured. That is, the measurement order of each event to be measured can be configured by configuring the start condition and stop condition of each event to be measured.

[0014] In one possible implementation of the first aspect of this application, the measurement based on a first measurement event among the events to be measured includes: determining the first measurement event from the events to be measured based on the first indication information; and performing measurement based on the first measurement event to obtain a first measurement report. In the above implementation, the terminal device can directly determine the first measurement event to be measured from multiple events to be measured based on the first indication information configured by the network device. That is, it can directly determine the first measurement event to be measured based on the measurement order of multiple events to be measured configured by the network device, and perform measurement on the first measurement event to obtain a first measurement report. This reduces the number of interactions between the layer 3 network device and the terminal device, thereby reducing the mobility latency of the terminal device.

[0015] In one possible implementation of the first aspect of this application, the method further includes: receiving second indication information, the second indication information being used to indicate that a first measurement event among the events to be measured is activated. In the above implementation, the network device may also send second indication information to the terminal device to indicate that the first measurement event is activated, enabling the terminal device to directly determine the first measurement event that needs to be measured from multiple events to be measured based on the second indication information, and to measure the first measurement event to obtain a first measurement report, thereby reducing the number of interactions between the network device's layer 3 and the terminal device, and thus reducing the mobility latency of the terminal device.

[0016] In one possible implementation of the first aspect of this application, receiving the second indication information includes: receiving the second indication information based on Media Access Control (MAC) CE signaling. In the above implementation, the second indication information can be carried on MAC CE signaling, meaning the network device can send the second indication information to the terminal device via MAC CE signaling, thereby reducing the number of Layer 3 interactions between the network device and the terminal device, and thus reducing the mobility latency of the terminal device.

[0017] In one possible implementation of the first aspect of this application, the method further includes: receiving third indication information, the third indication information being used to instruct the first measurement event to deactivate. In the above implementation, after the terminal device finishes measuring the first measurement event, it can receive third indication information from the network device to instruct the first measurement event to deactivate, and stop measuring the first measurement event, so that the terminal device can start measuring other measurement events among multiple events to be measured.

[0018] In one possible implementation of the first aspect of this application, sending the first measurement report includes: sending the first measurement report based on RRC signaling or MAC CE signaling. In the above implementation, the terminal device can choose to send the first measurement report to the network device based on RRC signaling or MAC CE signaling depending on the application scenario, thereby reducing the number of Layer 3 interactions between the network device and the terminal device, and thus reducing the mobility latency of the terminal device.

[0019] In one possible implementation of the first aspect of this application, the method further includes: performing a measurement based on a second measurement event among the events to be measured, and obtaining a second measurement report for the second measurement event; if the second measurement report meets the reporting conditions of the second measurement event, sending the second measurement report. In the above implementation, after the terminal device finishes measuring the first measurement event among multiple events to be measured, it can continue to determine new measurement events, i.e., second measurement events, from the multiple events to be measured and perform measurements, so as to reduce the number of interactions between the layer 3 network device and the terminal device, thereby reducing the mobility latency of the terminal device.

[0020] A second aspect of this application provides a communication method applied to a network device, the method comprising:

[0021] Send a Radio Resource Control (RRC) reconfiguration message, the RRC reconfiguration message including multiple events to be measured by the terminal device, so that the terminal device can perform measurement based on a first measurement event among the events to be measured and obtain a first measurement report of the first measurement event;

[0022] The terminal device receives the first measurement report when the first measurement report meets the reporting conditions of the first measurement event.

[0023] In the above implementation scheme, the network device can configure multiple measurands that the terminal device needs to measure at one time. This allows the terminal device to determine the first measurand from the multiple measurands and perform the measurement. When measuring again, the terminal device can directly determine the next measurand based on the previously acquired multiple measurands. This eliminates the need for the network device's Layer 3 to configure the next measurand through signaling, reducing the number of interactions between the network device's Layer 3 and the terminal device, thereby reducing the mobility latency of the terminal device.

[0024] In one possible implementation of the second aspect of this application, the RRC reconfiguration message further includes first indication information, which is used to indicate the measurement sequence of the events to be measured.

[0025] In one possible implementation of the second aspect of this application, the first indication information includes a first indication sub-information and a second indication sub-information, wherein the first indication sub-information is used to indicate the start condition of the event to be measured, and the second indication sub-information is used to indicate the stop condition of the event to be measured.

[0026] In one possible implementation of the second aspect of this application, the method further includes: sending second indication information, the second indication information being used to indicate that a first measurement event in the event to be measured is activated.

[0027] In one possible implementation of the second aspect of this application, the sending of the second indication information includes: sending the second indication information based on the Media Access Control Layer (MAC) control element (CE) signaling.

[0028] In one possible implementation of the second aspect of this application, the method further includes: sending third indication information, the third indication information being used to instruct the first measurement event to deactivate.

[0029] In one possible implementation of the second aspect of this application, receiving the first measurement report sent by the terminal device when the first measurement report meets the reporting conditions of the first measurement event includes: receiving the first measurement report based on RRC signaling or MAC CE signaling.

[0030] In one possible implementation of the second aspect of this application, the method further includes: receiving a second measurement report of a second measurement event.

[0032] The receiving module is configured to receive Radio Resource Control (RRC) reconfiguration messages, wherein the RRC reconfiguration messages include multiple measurable events of the terminal device;

[0033] The measurement module is used to perform measurements based on a first measurement event in the events to be measured, and to obtain a first measurement report for the first measurement event;

[0034] The sending module is used to send the first measurement report if the first measurement report meets the reporting conditions of the first measurement event.

[0035] A fourth aspect of this application provides a communication device, specifically a network device, comprising:

[0036] The transmitting module is used to transmit a Radio Resource Control (RRC) reconfiguration message, wherein the RRC reconfiguration message includes multiple events to be measured by the terminal device, so that the terminal device can perform measurement based on a first measurement event among the events to be measured and obtain a first measurement report of the first measurement event.

[0037] The receiving module is configured to receive the first measurement report sent by the terminal device when the first measurement report meets the reporting conditions of the first measurement event.

[0054] The communication system includes a first device and a second device. The first device can be a network-side device used to provide network communication functions; in some cases, it is also called a network device or network element. The network device can typically be a base station (including functional units of a base station, or a combination of functional units of base stations) or a core network unit. The core network unit can be a functional unit within the core network, including but not limited to Access and Mobility Management Function (AMF) units or Session Management Function (SMF) units. The second device can be a device accessing the network, typically a terminal device. An example of a communication system is shown in Figure 1, which includes a base station 11 and a terminal 12.

[0055] In the embodiments provided in this application, the base station can be any device with wireless transceiver capabilities, including but not limited to: evolved base stations (NodeB, eNB, or e-NodeB) in Long Term Evolution (LTE), base stations (gNodeB or gNB) or transmission receiving points / transmission reception points (TRPs) in New Radio (NR), base stations in subsequent 3GPP evolutions, access nodes in Wi-Fi systems, wireless relay nodes, wireless backhaul nodes, etc. The base station can be: macro base station, micro base station, pico base station, small cell, relay station, or balloon station, etc. The base station can contain one or more co-located or non-co-located transmission reception points (TRPs). The base station can also be a radio controller, centralized unit (CU), and / or distributed unit (DU) in a cloud radio access network (CRAN) scenario. The base station can communicate with terminal devices or communicate with terminal devices through relay stations. Terminal devices can communicate with multiple base stations using different technologies. For example, a terminal device can communicate with a base station that supports LTE networks, or with a base station that supports 5G networks, or even have dual connections with both LTE and 5G base stations.

[0056] In the embodiments provided in this application, the terminal device can take various forms, such as a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, vehicle-mounted terminal device, wireless terminal device in self-driving, wireless terminal device in remote medical care, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, wireless terminal device in smart home, wearable terminal device, etc. The terminal device may also be referred to as a terminal device, user equipment (UE), access terminal device, vehicle-mounted terminal device, industrial control terminal device, UE unit, UE station, mobile station, mobile station, remote station, remote terminal device, mobile device, UE terminal device, terminal device, wireless communication device, UE agent, or UE device, etc. The terminal device can also be a fixed terminal device or a mobile terminal device.

[0057] In communication systems, Low Layer Triggered Mobility (LTM) aims to improve network performance and user experience by optimizing mobility management mechanisms. LTM implements Layer 1 (L1) based measurement and handover, primarily supporting handover between different cells for terminal devices. By reducing data interruptions during handover, it enables the network to respond to UE mobility needs more quickly and accurately, thereby ensuring service continuity and stability.

[0058] The LTM mechanism typically involves signaling interactions between Layer 1, Layer 2 (L1), and Layer 3. Layer 1 usually refers to the Physical Layer, the lowest layer in the communication protocol stack. It is responsible for handling the physical transmission of data, including signal modulation, demodulation, encoding, decoding, synchronization, and the physical characteristics of the transmission medium. In 5G networks, Layer 1 is responsible for transmitting data over the wireless channel, ensuring signal reliability and effectiveness. In the LTM mechanism, Layer 1 provides basic physical layer measurements, such as signal quality and interference levels; these measurements form the basis for triggering the LTM process.

[0059] Layer 2 typically refers to the Data Link Layer, which provides data link control and error correction functions above the Physical Layer. In 5G networks, Layer 2 includes sublayers such as the Media Access Control (MAC) layer and the Radio Link Control (RLC) layer. The MAC layer is responsible for scheduling and multiplexing data from multiple users, as well as handling access control for the radio channel; the RLC layer is responsible for data segmentation, reassembly, and error correction. In the LTM mechanism, Layer 2, especially the MAC layer, triggers mobility handover through lower-layer signaling. When measurements from Layer 1 indicate that the current channel quality has degraded below a certain threshold, the MAC layer can decide to trigger a handover procedure to ensure the communication quality and continuity of user equipment.

[0060] Layer 3 typically refers to the Network Layer, which provides data transmission and routing functions between networks above the Data Link Layer. In 5G networks, Layer 3 includes sublayers such as the Radio Resource Control Layer (RRC), responsible for handling user equipment access control, mobility management, and session management. During the LTM mechanism process, when a terminal device switches to a new cell, the RRC layer needs to handle related signaling exchanges and state updates to ensure network access and session continuity for the user equipment.

[0061] Currently, when terminal equipment performs cell handover based on the LTM mechanism, it needs to measure network performance based on LTM measurement events to evaluate and optimize the mobility performance of user equipment. LTM measurement events are a series of events related to mobility management. These events are typically triggered by lower layers in the network, such as the physical layer and data link layer, and are used to evaluate and optimize the mobility performance of user equipment. Common LTM measurement events include the following three types:

[0062] 1. Signal quality related events:

[0063] Events such as A1 and A2 are typically triggered based on the signal quality of the serving cell or neighboring cells. For example, an A1 event might indicate that the serving cell's signal quality is above a certain threshold, while an A2 event might indicate that the serving cell's signal quality is below a certain threshold.

[0064] 2. Switch related events:

[0065] Events such as A3, A4, and A5 are typically used to trigger handover decisions based on coverage, load, or quality. For example, an A3 event might indicate that the quality of a neighboring cell is higher than that of the serving cell, used for coverage-based handovers on the same or different frequencies; an A4 event might indicate that the quality of a neighboring cell is higher than a certain threshold, used for load-based handovers; and an A5 event might indicate that the quality of the serving cell is lower than a certain threshold while the quality of a neighboring cell is higher than a certain threshold, used for load balancing.

[0066] 3. Heterogeneous system measurement events:

[0067] Events such as B1 and B2 are used to measure the quality of high-priority or same / lower-priority inter-system cells and may trigger handover or reselection to an inter-system.

[0068] Currently, when a terminal device performs measurements based on LTM measurement events, the Layer 3 layer of the network device configures the LTM measurement events that the terminal device needs to measure to the terminal device via RRC messages. The terminal device immediately executes the measurements for the LTM measurement events configured by the network device and reports a measurement report. After receiving the measurement report reported by the terminal device, the Layer 3 layer of the network device configures new LTM measurement events to the terminal device via RRC messages. That is, when the terminal device needs to perform measurements based on multiple LTM measurement events, the Layer 3 layer of the network device needs to perform multiple rounds of configuration for the LTM measurement events via multiple RRC messages, resulting in high mobility latency for the terminal device.

[0069] To make the technical solution of this application clearer and easier to understand, the communication method of the embodiments of this application is described below with reference to the accompanying drawings. The embodiments of this application are applicable to data transmission processes in wireless communication scenarios. In this embodiment, data transmission between a terminal device and a network device is taken as an example, such as data transmission between a single terminal device and a network device. The above-described data transmission between a terminal device and a network device is only a feasible example, and the embodiments of this application do not limit it.

[0070] Please refer to Figure 2, which shows a schematic diagram of an interaction process between a network device and a terminal device provided in an embodiment of this application. The communication method provided in this embodiment mainly includes the following steps:

[0071] 201. The network device sends an RRC reconfiguration message to the terminal device.

[0072] The RRC reconfiguration message includes multiple events to be measured on the terminal device.

[0073] In this embodiment, the network device can first configure the LTM measurement events that the terminal device can measure during cell handover based on the LTM mechanism, and then send multiple LTM measurement events that the terminal device can measure as measurable events to be measured to the terminal device at once via an RRC reconfiguration message. It is understood that the multiple measurable events configured by the network device to the terminal device at once can be all the LTM measurement events that the terminal device can measure, or all the LTM measurement events that the terminal device can measure during this cell handover. Specifically, the network device's Layer 3 can configure the multiple measurable events to the terminal device via an RRC reconfiguration message.

[0074] LTM measurement events can include measurement content and measurement objects, which can differ between different LTM measurement events. The measurement content can specifically refer to the details measured by the terminal device; the measurement object can be a specific cell, such as the current serving cell or neighboring cells. Different identifiers can be used to identify different LTM measurement events, such as LTM1, LTM2, LTM3, LTM4, and LTM5. Specifically, LTM1 indicates that the LTM measurement event measures whether the signal quality of the serving cell is above a certain threshold; LTM2 indicates that the LTM measurement event measures whether the signal quality of the serving cell is below a certain threshold; LTM3 indicates that the LTM measurement event measures whether the service quality of a neighboring cell is higher than that of the serving cell; LTM4 indicates that the LTM measurement event measures whether the service quality of a neighboring cell is above a certain threshold; and LTM5 indicates whether the service quality of the serving cell is below a certain threshold and the service quality of a neighboring cell is above a certain threshold. In addition, each LTM measurement event can also have corresponding reporting conditions. That is, during the measurement of an LTM measurement event, the terminal device will only report a measurement report to the network device when the reporting conditions are met.

[0075] In one possible implementation of this application embodiment, the RRC reconfiguration message further includes first indication information, which is used to indicate the measurement order of the events to be measured. In this application embodiment, the network device can set different measurement orders for different LTM measurement events according to actual conditions. That is, when the network device determines multiple events to be measured that the terminal device can measure, it can also configure the first indication information to indicate the measurement order of each of the multiple events to be measured. For example, when the multiple events to be measured that the terminal device can measure include LTM1, LTM2, and LTM5, the first indication information can be used to indicate that LTM2 is measured first, followed by LTM1 and LTM5.

[0076] In one possible implementation of this application embodiment, the first indication information includes a first indication sub-information and a second indication sub-information. The first indication sub-information is used to indicate the start condition of the event to be measured, and the second indication sub-information is used to indicate the stop condition of the event to be measured. In this application embodiment, the first indication information used to indicate the measurement sequence of the events to be measured can be composed of a first indication sub-information used to indicate the start condition of the events to be measured and a second indication sub-information used to indicate the stop condition of the events to be measured. That is, the measurement sequence of each event to be measured can be configured by configuring the start condition and the stop condition of each event to be measured. The start condition of the event to be measured can be a condition required to start the event to be measured, and the stop condition of the event to be measured can be a condition required to stop the event to be measured. For example, the start condition of LTM1 can be that the measurement report of LTM2 is reported to the network device, and the stop condition of LTM1 can be that the measurement report of LTM1 is reported to the network device.

[0077] In addition, it should be noted that when the first indication information includes the first indication sub-information and the second indication sub-information, the network device can also send the third indication sub-information to the terminal device to indicate which event to be measured should be measured first, that is, it can be used to indicate the initial measurement list.

[0078] For example, when multiple measurable events of a terminal device include LTM1, LTM2, and LTM5, the specific configuration in the RRC reconfiguration message sent by the network device to the terminal device can be as follows:

[0079] MeasureObject1: Serving cell;

[0080] MeasureObject2: Neighboring area;

[0081] ReportConfig1: LTM2;

[0082] ReportConfig2: LTM1;

[0083] ReportConfig3: LTM5;

[0084] MeasureID1: Associated with MeasureObject1 and ReportConfig1. Start condition: The measurement report corresponding to MeasureID2 is submitted. Stop condition: The measurement report corresponding to MeasureID1 is submitted, and the measurement of MeasureID1 is stopped.

[0085] MeasureID2: Associated with MeasureObject1 and ReportConfig2. Start condition: The measurement report corresponding to MeasureID1 is submitted. Stop condition: The measurement report corresponding to MeasureID2 is submitted, and MeasureID2 measurement is stopped.

[0086] MeasureID3: Associated with MeasureObject2 and ReportConfig5; Start condition: Measurement report corresponding to MeasureID1 is submitted; Stop condition: None.

[0087] Initial measurement list: MeasureID1.

[0088] Among them, MeasureObject1 and MeasureObject2 are different measurement objects, ReportConfig1, ReportConfig2 and ReportConfig3 are different measurement contents, and MeasureID1, MeasureID2 and MeasureID3 are different events to be measured.

[0089] 202. The terminal device receives a Radio Resource Control (RRC) reconfiguration message from the network device.

[0090] The RRC reconfiguration message includes multiple events to be measured on the terminal device.

[0091] In this embodiment of the application, when the network device sends an RRC reconfiguration message carrying multiple measurable events of the terminal device to the terminal device, the terminal device can receive the RRC reconfiguration message so that it can receive multiple measurable events that the terminal device needs to measure at one time, and enable the terminal device to determine the first measurement event to be measured from the multiple measurable events according to the requirements, thereby reducing the number of interactions between the layer 3 of the network device and the terminal device, and thus reducing the mobility latency of the terminal device.

[0092] 203. The terminal device performs a measurement based on the first measurement event in the event to be measured, and obtains the first measurement report of the first measurement event.

[0093] In this embodiment, when a terminal device receives multiple measurable events configured by a network device that require measurement, it can determine the first measurement event that needs to be measured from the multiple measurable events according to requirements. This allows for measurement based on the first measurement event, resulting in a first measurement report for the first measurement event. The first measurement report can be used to indicate the measurement result after the terminal device performs the measurement based on the first measurement event. For example, when the first measurement event is LTM2, the first measurement report can indicate that the signal quality of the serving cell is below a preset threshold.

[0094] Specifically, when the network device is also configured with the measurement order of each of the multiple events to be measured, the terminal device can determine the first measurement event that needs to be measured from the multiple events to be measured based on the measurement order of each event to be measured.

[0095] In one possible implementation of this application embodiment, in step 203, the terminal device performs a measurement based on the first measurement event in the event to be measured, and obtains a first measurement report of the first measurement event.

[0096] A1. The terminal device determines the first measurement event from the events to be measured based on the first indication information.

[0097] In this embodiment of the application, when the RRC reconfiguration message received by the terminal device from the network device also includes first indication information for indicating the measurement order of the measurement events of the event to be measured, the terminal device can determine the measurement order of each event to be measured according to the first indication information, and determine the first measurement event that needs to be measured at present according to the measurement order of each event to be measured.

[0098] A2. The terminal device performs measurements based on the first measurement event and obtains the first measurement report.

[0099] In this embodiment of the application, after determining the first measurement event from multiple events to be measured, the terminal device can determine the measurement object and measurement content in the first measurement event, and perform measurement based on the measurement object and measurement content in the first measurement event to obtain a first measurement report.

[0100] 204. If the first measurement report meets the reporting conditions for the first measurement event, the terminal device sends the first measurement report to the network device.

[0101] In this embodiment, after the terminal device performs a measurement based on a first measurement event and obtains a first measurement report for the first measurement event, it can first determine whether the first measurement report meets the reporting conditions of the first measurement event. If the first measurement report meets the reporting conditions of the first measurement event, the terminal device can report the first measurement report to the network device so that the network device can determine the measurement result of the terminal device based on the first measurement event. It is understood that each LTM measurement event can also be set with corresponding reporting conditions, that is, during the measurement process of the LTM measurement event, the terminal device will only report the measurement report to the network device when the reporting conditions are met. For example, when the first measurement event is LTM2, the reporting condition of the first measurement event can be set to the signal quality of the serving cell being lower than a preset threshold. If the measurement result indicated by the first measurement report is that the signal quality of the serving cell is lower than the preset threshold, the terminal device can report the first measurement report to the network device; if the measurement result indicated by the first measurement report is that the signal quality of the serving cell is higher than or equal to the preset threshold, the terminal device may not report the first measurement report to the network device.

[0102] In one possible implementation of this application embodiment, step 204, if the terminal device sends a first measurement report to the network device, includes:

[0103] B1. The terminal device sends the first measurement report to the network device based on RRC signaling or MAC CE signaling.

[0104] In this embodiment, the terminal device can choose to send a first measurement report to the network device based on RRC signaling or MAC CE signaling, depending on the application scenario. This reduces the number of interactions between the network device's Layer 3 and the terminal device, thereby lowering the terminal device's mobility latency. Specifically, if the terminal device performs measurements based on the RRC layer, it can send a first measurement report to the network device based on RRC signaling; if the terminal device performs measurements based on the LTM mechanism, it can send a first measurement report to the network device based on MAC CE signaling.

[0105] Furthermore, it should be noted that once the terminal device sends the first measurement report to the network device, it indicates that the first measurement event has been completed, and the terminal device can stop the measurement based on the first measurement event. The terminal device can also deactivate the first measurement event or delete it from multiple pending measurement events.

[0106] In one possible implementation of this application embodiment, the method further includes:

[0107] C1. The terminal device performs a measurement based on the second measurement event in the event to be measured, and obtains a second measurement report of the second measurement event.

[0108] In this embodiment, after the terminal device sends the first measurement report to the network device, and there are still measurement events that have not been measured among the multiple events to be measured, the terminal device can continue to determine the second measurement event that needs to be measured from the multiple events to be measured as needed, so that it can perform measurement based on the second measurement event and obtain the second measurement report of the second measurement event, thereby reducing the number of interactions between the layer 3 of the network device and the terminal device, and thus reducing the mobility latency of the terminal device.

[0109] C2. If the second measurement report meets the reporting conditions for the second measurement event, the terminal sends the second measurement report to the network device.

[0110] In this embodiment, after the terminal device performs a measurement based on the second measurement event and obtains a second measurement report for the second measurement event, it can first determine whether the second measurement report meets the reporting conditions of the second measurement event. If the second measurement report meets the reporting conditions of the second measurement event, the terminal device can report the second measurement report to the network device so that the network device can determine the measurement result of the terminal device based on the second measurement event.

[0111] As illustrated by the examples in the foregoing embodiments, the network device can configure multiple measurand events that the terminal device needs to measure at once. The terminal device can determine the first measurand event to be measured from the multiple measurand events as needed. When measuring again, it can also directly determine the next measurand event to be measured based on the multiple measurand events previously acquired, without the need for the network device's Layer 3 to configure the next measurand event through signaling. This reduces the number of interactions between the network device's Layer 3 and the terminal device, thereby reducing the mobility latency of the terminal device.

[0112] Please refer to Figure 3, which shows another interaction flow diagram between the network device and the terminal device provided in the embodiment of this application. Another communication method provided in the embodiment of this application mainly includes the following steps:

[0113] 301. The network device sends an RRC reconfiguration message to the terminal device.

[0114] 302. The terminal device receives a Radio Resource Control (RRC) reconfiguration message from the network device.

[0115] The specific content of steps 301-302 is similar to steps 201-202 in the above embodiments, and will not be repeated here.

[0116] 303. The network device sends a second instruction message to the terminal device.

[0117] The second indication information is used to indicate that the first measurement event in the event to be measured is activated.

[0118] In this embodiment, after the network device configures multiple measurands that the terminal device needs to measure to the terminal device at once via RRC reconfiguration messages, it can send a second indication message to the terminal device to indicate that the first measurement event among the measurands is active. This allows the terminal device to determine the first measurement event that needs to be measured from the multiple measurands and perform the measurement. Indicating the first measurement event is active means changing the first measurement event from an inactive state to an active state. It is understood that the network device can instruct the terminal device to measure the first measurement event among the multiple measurands by sending the second indication message, without needing to instruct the terminal device to measure the first measurement event through immediate configuration of the first measurement event by Layer 3. This reduces the number of interactions between Layer 3 of the network device and the terminal device, thereby reducing the mobility latency of the terminal device.

[0119] In one possible implementation of this application embodiment, step 303, where the network device sends second indication information to the terminal device, includes:

[0120] D1. The network device sends a second instruction message to the terminal device based on MAC CE signaling.

[0121] In this embodiment of the application, the second indication information can be carried on MAC CE signaling, that is, the network device can send the second indication information to the terminal device through MAC CE signaling to reduce the number of interactions between the network device's layer 3 and the terminal device, thereby reducing the mobility latency of the terminal device.

[0122] 304. The terminal device receives a second instruction from the network device.

[0123] In this embodiment, the terminal device can receive second indication information from the network device, enabling the terminal device to determine the first measurement event that needs to be measured from multiple events to be measured. It is understood that the network device can instruct the terminal device to measure the first measurement event from the multiple events to be measured by sending the second indication information, without requiring Layer 3 to configure the first measurement event in real-time to instruct the terminal device to measure it. This reduces the number of interactions between Layer 3 of the network device and the terminal device, thereby reducing the mobility latency of the terminal device.

[0124] In one possible implementation of this application embodiment, step 304, the terminal device receives second indication information from the network device, including:

[0125] E1. The terminal device receives the second indication information from the network device based on MAC CE signaling.

[0126] In this embodiment of the application, the second indication information can be carried on MAC CE signaling, that is, the network device can send the second indication information to the terminal device through MAC CE signaling to reduce the number of interactions between the network device's layer 3 and the terminal device, thereby reducing the mobility latency of the terminal device.

[0127] 305. The terminal device performs a measurement based on the first measurement event in the event to be measured, and obtains the first measurement report of the first measurement event.

[0128] In this embodiment, after the terminal device receives second indication information indicating the activation of a first measurement event, it can determine the first measurement event that needs to be measured from a plurality of events to be measured, and perform measurement based on the first measurement event to obtain a first measurement report for the first measurement event. Specifically, the terminal device can directly determine the activated first measurement event from a plurality of events to be measured and perform measurement. The first measurement report of the first measurement event can be used to indicate the measurement result after the terminal device performs measurement based on the first measurement event. For example, when the first measurement event is LTM2, the first measurement report can be that the signal quality of the serving cell is lower than a preset threshold.

[0129] 306. If the first measurement report meets the reporting conditions for the first measurement event, the terminal device sends the first measurement report to the network device.

[0130] The specific content of step 306 is similar to step 204 in the above embodiment, and will not be repeated here.

[0131] 307. The network device sends a third instruction message to the terminal device.

[0132] The third indication information is used to instruct the first measurement event to be deactivated.

[0133] In this embodiment, when the network device determines that it needs to instruct the terminal device to stop measuring based on the first measurement event, it can send a third indication message to the terminal device to instruct the terminal device to deactivate the first measurement event. Instructing the first measurement event to deactivate means changing the first measurement event from an active state to an inactive state. Specifically, after receiving the first measurement report reported by the terminal device, the network device can send the third indication message to the terminal device based on MAC CE signaling, so that the terminal device can stop measuring based on the first measurement event. This reduces the number of Layer 3 interactions between the network device and the terminal device, thereby reducing the mobility latency of the terminal device.

[0134] 308. The terminal device receives third instruction information from the network device.

[0135] In this embodiment, the terminal device can receive third indication information sent by the network device to instruct the deactivation of the first measurement event, and stop performing measurements based on the first measurement event after receiving the third indication information. Specifically, after reporting the first measurement report of the first measurement event to the network device, the terminal device can receive the third indication information from the network device based on MAC CE signaling, so that the terminal device can stop performing measurements based on the first measurement event, reducing the number of interactions between the layer 3 network device and the terminal device, thereby reducing the mobility latency of the terminal device.

[0136] As illustrated by the examples in the foregoing embodiments, the network device can configure multiple measurable events that the terminal device needs to measure at once to the terminal device. The terminal device can determine the first measurement event to be measured from the multiple measurable events based on the second instruction information sent by the network device. When measuring again, the next measurement event to be measured can be determined directly based on the multiple measurable events previously acquired, without the need for the network device's layer 3 to configure the next measurement event to be measured through signaling. This reduces the number of interactions between the network device's layer 3 and the terminal device, thereby reducing the mobility latency of the terminal device.

[0157] As illustrated by the examples in the foregoing embodiments, the network device can configure multiple measurand events that the terminal device needs to measure at once. The terminal device can determine the first measurand event to be measured from the multiple measurand events as needed. When measuring again, it can also directly determine the next measurand event to be measured based on the multiple measurand events previously acquired, without the need for the network device's Layer 3 to configure the next measurand event through signaling. This reduces the number of interactions between the network device's Layer 3 and the terminal device, thereby reducing the mobility latency of the terminal device.

This electronic device may be a first device, including but not limited to a base station and a core network unit. Figure 6 shows a simplified schematic diagram of a base station structure.
