Description

Technical Field

[0001] This application relates to the field of communications, and more specifically, to a communication method and a communication device. Background Technology

[0002] Compared to stationary or slow-moving terminal devices, high-speed moving terminal devices (such as those on high-speed trains and mobile communication devices within high-speed trains) exhibit unstable signal quality variations, easily causing ping-pong handover problems when switching between two cells. Furthermore, high-speed moving terminal devices have shorter transit times through coverage areas where cell handover is possible, potentially less than the minimum delay required for system handover completion, which can easily lead to network connection interruptions and negatively impact communication quality.

[0003] Currently, a cell merging solution has been proposed for railway scenarios, which merges multiple independent TRPs in a continuous coverage area into one cell to reduce handover issues in high-speed scenarios by reducing the number of handovers for terminal devices. However, the application scenarios of this solution are limited, and the aforementioned handover issues still exist at the boundary between two cells. Summary of the Invention

[0004] This application provides a communication method and a communication device to improve the communication reliability of terminal devices.

[0005] In a first aspect, a communication method is provided, which can be executed by a terminal device or a module (such as a chip) configured in (or used in) the terminal device.

[0006] The method includes: receiving a reference signal from an access network device; obtaining a target parameter value based on the reference signal, the target parameter value including at least one of a target angle or a target distance, the target angle being the angle between the line connecting the access network device and the terminal device and the direction of movement of the terminal device, and the target distance being the ground distance between the access network device and the terminal device; and determining a reporting threshold as a first threshold value, the first threshold value being the threshold value corresponding to the parameter value interval in which the target parameter value is located, the reporting threshold being used to determine whether to send a measurement report.

[0007] According to the above scheme, the terminal device can determine the threshold value for sending measurement reports based on the relative positional relationship between the terminal device and the access network device. This makes the timing of the terminal device sending measurement reports to the access network device related to this relative positional relationship, reducing the probability of communication quality degradation such as ping-pong handover or late handover caused by signal quality fluctuations, resulting in interruptions in the connection between the terminal device and the network. This improves the communication reliability of the terminal device.

[0008] In conjunction with the first aspect, in some implementations of the first aspect, determining the reporting threshold as a first threshold value includes: determining the range of parameter values ​​in which the target parameter value lies; and determining a threshold compensation amount based on the parameter value range. The first threshold value is determined based on a second threshold value and the threshold compensation amount, wherein the second threshold value is the threshold value of the reporting threshold configured by the access network device for the terminal device.

[0009] According to the above scheme, the terminal device can use the second threshold value configured by the access network device as a benchmark, determine the threshold compensation amount based on the parameter value range where the target parameter value is located, and perform threshold compensation based on the second threshold value. The threshold compensation amount can be a positive compensation amount or a negative compensation amount.

[0010] In conjunction with the first aspect, in certain implementations of the first aspect, when the equivalent horizontal distance between the access network device and the terminal device, represented by the parameter value range, is less than or equal to a first distance, the threshold compensation amount is a positive compensation amount. When the equivalent horizontal distance, represented by the parameter value range, is greater than a second distance, the threshold compensation amount is a negative compensation amount. Wherein, the second distance is greater than the first distance.

[0011] According to the above scheme, when the equivalent horizontal distance between the terminal device and the first access network device of the serving cell is less than or equal to the first distance, the terminal device can delay sending the measurement report, reducing the probability of ping-pong handover caused by signal quality fluctuations, thereby improving the communication quality of the terminal device. When the equivalent horizontal distance between the terminal device and the first access network device is greater than the second distance, the terminal device can send the measurement report in advance, reducing the possibility of the terminal device disconnecting from the network due to insufficient network handover preparation time, thereby improving the communication quality of the terminal device.

[0012] In conjunction with the first aspect, in some implementations of the first aspect, the reporting threshold includes at least one of a signal quality threshold or a time threshold, and the measurement report is sent when the measurement result of the cell measurement performed by the terminal device meets the first threshold value.

[0013] According to the above scheme, the terminal device can determine at least one of a signal quality threshold or a time threshold for sending measurement reports based on the relative positional relationship between the terminal device and the access network device. This makes the timing of the terminal device sending measurement reports to the access network device related to the relative positional relationship, reducing the probability of communication quality degradation such as ping-pong handover or late handover caused by signal quality fluctuations, resulting in interruptions in the connection between the terminal device and the network. This improves the communication reliability of the terminal device.

[0014] In conjunction with the first aspect, in certain implementations of the first aspect, the measurement report is used to indicate cell signal quality that meets a second threshold value, the cell signal quality including the signal quality of the serving cell of the terminal device and / or the signal quality of a first cell, the first cell being a cell other than the serving cell of the terminal device, and the second threshold value being a threshold value of the reporting threshold configured by the access network device for the terminal device.

[0015] In a second aspect, a communication device is provided. In one design, the device may include modules corresponding to the methods / operations / steps / actions described in the first aspect. These modules may be hardware circuits, software, or a combination of hardware circuits and software. In one design, the device includes: a transceiver unit for receiving a reference signal from an access network device; and a processing unit for obtaining a target parameter value based on the reference signal. The target parameter value includes at least one of a target angle or a target distance. The target angle is the angle between the line connecting the access network device and the terminal device and the direction of movement of the terminal device. The target distance is the ground distance between the access network device and the terminal device. The processing unit is further configured to determine a reporting threshold as a first threshold value. The first threshold value is the threshold value corresponding to the parameter value interval where the target parameter value is located. This reporting threshold is used to determine whether to send a measurement report.

[0016] In conjunction with the second aspect, in some implementations of the second aspect, the processing unit is specifically used for:

[0017] Determine the range of values ​​for the target parameter;

[0018] Determine the threshold compensation amount based on the range of this parameter value;

[0019] The first threshold value is determined based on the second threshold value and the threshold compensation amount, and the second threshold value is the threshold value of the reporting threshold configured by the access network device for the terminal device.

[0020] In conjunction with the second aspect, in certain implementations of the second aspect, when the equivalent horizontal distance between the access network device and the terminal device, represented by the parameter value range, is less than or equal to the first distance, the threshold compensation amount is a positive compensation amount. When the equivalent horizontal distance, represented by the parameter value range, is greater than the second distance, the threshold compensation amount is a negative compensation amount. Wherein, the second distance is greater than the first distance.

[0021] In conjunction with the second aspect, in some implementations of the second aspect, the reporting threshold includes at least one of a signal quality threshold or a time threshold, and the transceiver unit is also used to send the measurement report when the measurement result of the cell measurement performed by the terminal device meets the first threshold value.

[0022] In conjunction with the second aspect, in some implementations of the second aspect, the measurement report is used to indicate cell signal quality that meets a second threshold value, the cell signal quality including the signal quality of the serving cell of the terminal device and / or the signal quality of a first cell, the first cell being a cell other than the serving cell of the terminal device, and the second threshold value being a threshold value of the reporting threshold configured by the access network device for the terminal device.

[0046] It should be understood that this application does not limit the specific form of the terminal device.

[0047] The network device in this application embodiment can be a device with wireless transceiver capabilities in the access network. This device includes, but is not limited to: base stations, evolved node Bs (eNBs), radio network controllers (RNCs), node Bs (NBs), base station controllers (BSCs), base transceiver stations (BTSs), home base stations (e.g., home evolved node Bs, or home node Bs, HNBs), baseband units (BBUs), access points (APs), wireless relay nodes, wireless backhaul nodes, transmission points (TPs), or transmission and reception points (TRPs) in a Wi-Fi system.

[0048] In some deployments, a gNB may include a centralized unit (CU) and a DU. A gNB may also include an active antenna unit (AAU).

[0049] The following is combined with Figure 2 This section describes the cell measurement and cell handover process of the terminal equipment. For example... Figure 2 As shown, in S201, the source access network device sends measurement configuration information to the terminal device, configuring the measurement parameters for performing cell measurements and the reporting threshold for sending measurement reports. The terminal device performs cell measurements based on the measurement configuration information, measuring the signal quality of the serving cell and the signal quality of cells other than the serving cell (which can be called neighboring cells). In S202, if the measurement results obtained from the cell measurements meet the reporting threshold, the terminal device sends a measurement report to the source access network device in S203. This measurement report includes the measurement results of the cell measurements performed by the terminal device. After receiving the measurement report, the source access network device determines, in S204, to hand over the terminal device to the target cell based on the measurement report. In S205, the source access network device sends handover information to the terminal device, instructing the terminal device to hand over to the target cell. After receiving the handover information in S205, the terminal device performs a cell handover from the source cell to the target cell managed by the target access network device.

[0050] according to Figure 2 As shown in the cell measurement and handover process, the access network equipment determines the serving cell for the handover terminal equipment based on the measurement results reported by the terminal equipment. Therefore, this application proposes that for high-speed mobile terminal equipment, the timing for the terminal equipment to send measurement reports to the access network equipment can be determined based on the relative positional relationship between the terminal equipment and the access network equipment. This can reduce the probability of communication quality degradation, such as ping-pong handover caused by signal quality fluctuations and premature handover leading to interruption of the terminal equipment's connection with the network, thus improving the communication quality of the terminal equipment.

[0051] The communication method provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0052] Figure 3 This is a schematic flowchart of a communication method provided in an embodiment of this application. Figure 3 The first access network device shown is the management device. Figure 3 The terminal device shown is the access network equipment of the serving cell.

[0053] S301, the terminal device receives a reference signal from the first access network device.

[0054] The terminal device receives a reference signal from the access network device so as to obtain the target parameter value in S302 based on the reference signal.

[0055] By way of example and without limitation, the reference signal is either a tracking reference signal (TRS) or a channel state information-reference signal (CSI-RS).

[0056] S302, the terminal device obtains target parameter values ​​based on the reference signal. The target parameter values ​​include at least one of target angle or target distance. The target angle is the angle between the line connecting the first access network device and the terminal device and the direction of movement of the terminal device. The target distance is the ground distance between the first access network device and the terminal device.

[0057] The target parameter value is used to characterize the relative positional relationship between the terminal device and the first access network device. The target parameter may include at least one of a target angle or a target distance. The terminal device can determine the reporting threshold for the measurement report in S303 based on the target parameter value.

[0058] The relative motion of the terminal device with respect to the first access network device generates the Doppler effect, resulting in a Doppler frequency offset in the reference signal received by the terminal device. This Doppler frequency offset Δf is related to the carrier frequency f, the speed of light c, the moving speed v of the terminal device, and the angle θ between the direction of signal arrival and the direction of movement. The Doppler frequency offset Δf can be expressed by the following equation:

[0059]

[0060] If the target parameter value includes the target angle, the terminal device can obtain the phase offset of the received reference signal. Based on the obtained phase offset, the Doppler frequency offset Δf can be calculated. Then, based on the above formula, the target angle can be determined. That is, the angle θ between the direction of arrival of the reference signal (i.e., the line connecting the first access network device and the terminal device) and the direction of motion of the terminal device satisfies the following formula:

[0061]

[0062] If the target parameter value includes a target distance, the terminal device can use ranging technology based on the reference signal to obtain the ground distance between the terminal device and the first access network device. For example, the terminal device can obtain the ground distance between the first access network device and the terminal device based on the received reference signal, using carrier phase ranging technology and / or time of arrival (TOA) ranging technology.

[0063] S303, the terminal device determines a first threshold value for the reporting threshold. The first threshold value is the threshold value corresponding to the parameter value interval where the target parameter value is located. The reporting threshold is used to determine whether to send a measurement report.

[0064] The terminal device determines a reporting threshold for sending cell measurement reports based on at least one of the target angle or target distance. This ensures that the timing of the terminal device sending the measurement report to the first access network device is related to the relative position of the terminal device and the first access network device. This reduces the probability of communication quality degradation, such as ping-pong handover or late handover caused by signal quality fluctuations, leading to interruptions in the connection between the terminal device and the network. Ultimately, this improves the communication quality of the terminal device.

[0065] Optionally, the terminal device can adjust the reporting threshold value based on the target parameter value and the terminal device's moving speed.

[0066] For example, when the moving speed of the terminal device exceeds a preset speed threshold, the terminal device can obtain the target parameter value based on the reference signal and determine the reporting threshold based on the target parameter value.

[0067] The terminal device determines the first threshold value of the reporting threshold, including but not limited to the following two implementation methods: Implementation Method 1 and Implementation Method 2.

[0068] In the first implementation method, the terminal device determines the parameter value range in which the target parameter value lies, determines the threshold compensation amount based on the parameter value range, and then determines the first threshold value of the reporting threshold based on the second threshold value and the threshold compensation amount. The terminal device then determines whether to send a measurement report to the first access network device based on the first threshold value. The second threshold value is the threshold value of the reporting threshold configured by the first access network device for the terminal device.

[0069] Optionally, when the equivalent horizontal distance between the first access network device and the terminal device, represented by the parameter value range, is less than or equal to the first distance, the threshold compensation amount is a positive compensation amount. When the equivalent horizontal distance between the first access network device and the terminal device, represented by the parameter value range, is greater than the second distance, the threshold compensation amount is a negative compensation amount. The second distance is greater than the first distance.

[0070] For example, the target parameter value includes the target angle. The terminal device determines the angle range in which the target angle is located. The terminal device can determine the threshold compensation amount corresponding to the angle range in which the target angle is located based on the correspondence between the angle range and the threshold compensation amount shown in Table 1.

[0071] Optionally, the correspondence between the angle range and the threshold compensation amount is predefined (such as the terminal equipment is configured at the factory), or the access network equipment is pre-configured for the terminal equipment.

[0072] like Figure 4 As shown, if the terminal device determines that the angle range of the target angle is θ1 < θ ≤ 180° - θ1, that is, when the terminal device is in a position between position A and position C, the terminal device can determine that the threshold compensation amount is a positive compensation amount, i.e., Δx, x > 0, according to the correspondence shown in Table 1. The terminal device sets the second threshold value x of the reporting threshold configured in the first access network device. th Based on this, the first threshold value x is obtained by compensating Δx. th +Δx. The terminal device will... th +Δx serves as the threshold value for the measurement report, determining whether to send a measurement report to the first access network device.

[0073] like Figure 5 As shown, if the terminal device determines that the target angle falls within the angle range of 0 ≤ θ < θ2 or 180° - θ2 ≤ θ < 180°, and the terminal device is located away from the first access network device (beyond position D or position E), then the terminal device can determine that the threshold compensation amount is a negative compensation amount, i.e., -Δx. Where θ1 ≥ θ2. The terminal device uses the second threshold value x... thBased on the compensation of -Δx, the first threshold value is obtained as x. th -Δx, x < x th The terminal device will x th -Δx serves as the threshold value for the measurement report, determining whether to send a measurement report to the first access network device.

[0074] Table 1

[0075] Angle range Threshold compensation amount <![CDATA[θ1≤θ≤180°-θ1]]> Δx <![CDATA[0≤θ<θ2,180°-θ2<θ<180°]]> -Δx

[0076] For example, the target parameter value includes the target distance. The terminal device determines the target distance interval in which the target distance is located. The terminal device can determine the threshold compensation amount corresponding to the target distance interval in which the target distance is located based on the correspondence between the target distance interval and the threshold compensation amount shown in Table 2.

[0077] Table 2

[0078] Target distance range Threshold compensation amount <![CDATA[d A ≤d≤d B ]]> Δx <![CDATA[d>d D ]]> -Δx

[0079] Optionally, the correspondence between the target distance interval and the threshold compensation amount is predefined (such as the terminal equipment's factory configuration), or the access network equipment is pre-configured for the terminal equipment.

[0080] like Figure 4 As shown, if the terminal device determines that the target distance range is d... A ≤d≤d B That is, when the terminal device is in a position between position A and position C, the threshold compensation amount can be determined to be a positive compensation amount, i.e., Δx. The terminal device will then use x... th +Δx serves as the threshold value for the measurement report, determining whether to send a measurement report to the first access network device.

[0081] like Figure 5 As shown, if the terminal device determines that the target distance interval is d>d D When the terminal device is located at a position other than location D or location E, far away from the first access network device, the terminal device can determine that the threshold compensation amount is a negative compensation amount, i.e., -Δx. Where d A ≤d D The terminal device will x th -Δx serves as the threshold value for the measurement report, determining whether to send a measurement report to the first access network device.

[0082] In other words, when the equivalent horizontal distance between the first access network device and the terminal device, represented by the angle interval where the target angle is located or the target distance interval where the target distance is located, is less than or equal to the first distance d1, the threshold compensation amount is a positive compensation amount, i.e., Δx, where d1 = d Acosθ1, such as Figure 4 As shown. When the horizontal distance between the first access network device and the terminal device, represented by this angle interval or target distance interval, is greater than the second distance, the threshold compensation amount is a negative compensation amount, i.e., -Δx, where d2 = d D cosθ2, such as Figure 5 As shown. Where d1≤d2.

[0083] like Figure 4 , Figure 5 As shown, the smaller the equivalent horizontal distance between the first access network device and the terminal device, as represented by the parameter value range (such as the angle range or the target distance range), the closer the terminal device is to the access network device of the first cell (i.e., the cell other than the serving cell). The farther the terminal device is from the access network device of the first cell, the more likely the terminal device can raise the threshold value of the reporting threshold so that the terminal device can delay sending the measurement report. This can reduce the ping-pong handover caused by the fluctuation of cell signal quality and improve the communication quality of the terminal device.

[0084] The smaller the equivalent horizontal distance between the first access network device and the terminal device, as represented by the parameter value range (such as angle range or target distance range), the farther the terminal device is from the first access network device and the closer the terminal device is to the access network device of the first cell. The terminal device can lower the reporting threshold value so that it can send measurement reports as early as possible, allowing the network sufficient time to prepare for handover and switch the terminal device to the target cell. This reduces the risk of disconnection due to delayed handover caused by high speeds, thus improving the communication quality of the terminal device.

[0085] For example, the target parameter values ​​may include the target angle and the target distance. The terminal device can determine the equivalent horizontal distance between the first access network device and the terminal device based on the target angle and the target distance. The terminal device can determine the distance interval corresponding to the equivalent horizontal distance. When the distance interval is less than or equal to the first distance, the threshold compensation amount is a positive compensation amount; when the distance interval is greater than the second distance, the threshold compensation amount is a negative compensation amount.

[0086] Optionally, the reporting threshold includes at least one of a signal quality threshold or a time threshold. When the measurement result of the cell measurement performed by the terminal device meets the first threshold value, the terminal device sends the measurement report to the first access network device.

[0087] In one example, the reporting threshold is a signal quality threshold. For instance, the first access network device configures the terminal device to measure the signal quality of the serving cell and the first cell using measurement configuration information. The reporting threshold includes a signal quality threshold, and the first access network device configures the threshold value of the signal quality threshold to be a second threshold value. When the signal quality of the first cell is higher than that of the serving cell, and the signal quality deviation meets the signal quality threshold, the terminal device sends a measurement report to the first access network device.

[0088] For example, terminal devices in such Figure 4 When the terminal device determines the reporting threshold compensation amount as Δx, it is positioned between locations A and B. RSRP That is, the threshold value for the reporting threshold is After performing cell signal quality measurement, the terminal device determines that the signal quality of the first cell is higher than that of the serving cell, and the signal quality deviation is greater than or equal to... The terminal device determines to send a measurement report to the first access network device. Optionally, the first access network device also configures a time threshold value, or trigger time threshold (TTT), for triggering the sending of the measurement report through measurement configuration information. The terminal device sends a measurement report to the first access network device when the elapsed time after the measurement result of the terminal device meets the signal quality threshold meets the trigger time threshold. When the terminal device determines that the signal quality deviation is greater than or equal to... When the elapsed time is greater than or equal to the time threshold, the terminal device sends the measurement report to the first access network device. In other words, when the equivalent horizontal distance between the terminal device and the first access network device is less than or equal to the first distance, by increasing the threshold value of the signal quality threshold, the terminal device can delay sending the measurement report, reduce the probability of ping-pong handover caused by signal quality fluctuations, and thus improve the communication quality of the terminal device.

[0089] For example, terminal devices in such Figure 5 When the terminal device is located at a position other than position D or position E, which is far away from the first access network device, the threshold compensation amount for determining the signal quality threshold is -Δx. RSRP That is, the threshold value for the reporting threshold is After performing cell signal quality measurement, the terminal device determines that the signal quality of the first cell is higher than that of the serving cell, and the signal quality deviation is greater than or equal to... The terminal device determines to send a measurement report to the first access network device. Optionally, the first access network device further configures a time threshold value for triggering the sending of the measurement report through measurement configuration information. When the terminal device determines that the signal quality deviation is greater than or equal to... When the elapsed time is greater than or equal to the time threshold, the terminal device sends the measurement report to the first access network device. In other words, when the equivalent horizontal distance between the terminal device and the first access network device is greater than the second distance, by lowering the threshold value of the signal quality threshold, the terminal device can send the measurement report in advance, reducing the possibility of the terminal device disconnecting from the network due to insufficient network handover preparation time, thereby improving the communication quality of the terminal device.

[0090] Optionally, the measurement report is used to indicate the cell signal quality, which meets a second threshold value. The cell signal quality includes the signal quality of the serving cell of the terminal device and / or the signal quality of a first cell, which is a cell other than the serving cell of the terminal device. The second threshold value is the threshold value of the reporting threshold configured by the first access network device for the terminal device.

[0091] The measurement results for this community meet the second threshold value. When the terminal device raises the signal quality threshold to If the terminal device sends a measurement report at this time, it indicates that the signal quality deviation is greater than or equal to the threshold value. Therefore, the signal quality of the serving cell and the signal quality of the first cell meet the second threshold value. That is, the signal quality deviation of the first cell being higher than that of the serving cell is greater than the second threshold value. The cell signal quality indicated in this measurement report can be the cell signal quality measured by the terminal equipment.

[0092] However, when the terminal device lowers the signal quality threshold to... If the terminal device sends a measurement report, it indicates that the signal quality deviation between the signal quality of the first cell and the signal quality of the serving cell measured by the terminal device is greater than or equal to a threshold value. However, the signal quality deviation is not necessarily greater than or equal to... Since the measurement report of the terminal device needs to meet the threshold configured by the first access network device, the signal quality of the serving cell indicated by the measurement report of the terminal device and the signal quality of the first cell need to meet the second threshold value, that is, the signal quality deviation between the signal quality of the first cell indicated by the measurement report and the signal quality of the serving cell indicated by the measurement report is greater than or equal to the second threshold value.

[0093] For example, the second threshold value of the signal quality threshold configured by the first access network device for the terminal device. The threshold compensation for determining the signal quality threshold by the terminal equipment is -Δx, which is 2 dBm relative to one milliwatt.RSRP If the signal quality threshold is -1dBm, the terminal device will adjust the signal quality threshold to the first threshold value, i.e., 1dBm. The terminal device then measures the signal quality of the first cell. Signal quality higher than the serving cell and If the signal quality is greater than the first threshold, meaning the terminal device determines that the cell measurement result meets the first threshold, the terminal device sends a measurement report. This measurement report indicates that the signal quality of the first cell is [value missing]. And indicated the signal quality of the serving cell. but The signal quality of the first cell as indicated in the measurement report Greater than the measurement obtained by the terminal device And the signal quality of the serving cell indicated in the measurement report. It can be equal to the signal quality of the serving cell measured by the terminal device. Make or This application does not impose any limitations on this.

[0094] The above explanation uses the example of configuring the terminal device to send a measurement report under the condition that the signal quality of the first cell is higher than that of the serving cell, and that the signal quality deviation meets the threshold value of the signal quality threshold. However, this application is not limited to this. The first access network device can configure the terminal device to send a measurement report under the condition that the signal quality of the first cell meets the threshold value of the signal quality threshold. The first access network device can configure the threshold value of this signal quality threshold (i.e., an example of the second threshold value) for the terminal device. For example, the first cell and the serving cell use different radio access technologies (RATs), or the first cell is a heterogeneous cell of the serving cell. The terminal device can adjust the threshold value of the signal quality threshold based on the obtained relative positional relationship between the terminal device and the first access network device, and determine whether to send a measurement report based on the adjusted threshold value. If the terminal device sends a measurement report after lowering the threshold value of the signal quality threshold, the measurement report indicates that the signal quality of the first cell meets the second threshold value of the signal quality threshold configured by the first access network device.

[0095] In another example, the reporting threshold includes a time threshold that triggers the terminal device to send a measurement report. For instance, the first access network device configures the terminal device to perform cell signal quality measurements using measurement configuration information. When the cell signal quality meets the threshold value of the signal quality threshold, and the elapsed time meets the threshold value of the time threshold, the terminal device sends a measurement report to the first access network device. The first access network device configures a second threshold value for this time threshold for the terminal device. The terminal device can adjust the threshold value of the time threshold based on the relative positional relationship between the terminal device and the first access network device.

[0096] For example, terminal devices in such Figure 4 When the terminal device determines the threshold compensation amount for the time threshold between positions A and B as shown, the threshold compensation amount is Δx. Time That is, the threshold value of the time threshold is The terminal device performs cell signal quality measurement, and the elapsed time after the cell signal quality meets the signal quality threshold is greater than or equal to... At this time, the terminal device sends a measurement report to the first access network device. That is to say, when the equivalent horizontal distance between the terminal device and the first access network device of the serving cell is less than or equal to the first distance, the terminal device can delay sending the measurement report, reducing the probability of ping-pong handover caused by signal quality fluctuations, thereby improving the communication quality of the terminal device.

[0097] For example, terminal devices in such Figure 5 When the terminal device is located at a position other than position D or position E, which is far away from the first access network device, the threshold compensation amount for determining the time threshold is -Δx. Time That is, the threshold value of the time threshold is The terminal device performs cell signal quality measurement. The elapsed time after the cell signal quality meets the threshold value is greater than or equal to... The terminal device sends a measurement report to the first access network device. In other words, when the equivalent horizontal distance between the terminal device and the first access network device is greater than the second distance, the terminal device can send a measurement report in advance, reducing the possibility of the terminal device disconnecting from the network due to insufficient network handover preparation time, thereby improving the communication quality of the terminal device.

[0098] Optionally, when the reporting threshold includes a time threshold, the terminal device can determine whether the signal quality meets the signal quality threshold based on the threshold value of the signal quality threshold configured by the first access network device. Alternatively, the above two examples can be implemented in combination, where the reporting threshold includes both a signal quality threshold and a time threshold. The terminal device adjusts both the threshold values ​​of the signal quality threshold and the time threshold based on the relative positional relationship between the terminal device and the first access network device, as represented by the target parameter value. For example, when the equivalent horizontal distance between the terminal device and the first access network device is less than or equal to a first distance, the terminal device determines the threshold compensation amount Δx for the signal quality threshold. RSRP And the threshold compensation amount Δx of the time threshold TimeThe terminal device determines whether to send a measurement report to the first access network device based on the signal quality threshold after compensation and the time threshold. This reduces the probability of ping-pong handover caused by signal quality fluctuations, thereby improving the communication quality of the terminal device. For example, when the equivalent horizontal distance between the terminal device and the first access network device is less than or equal to a first distance, the terminal device determines the threshold compensation amount -Δx for the signal quality threshold. RSRP And the threshold compensation amount for the time threshold -Δx Time The terminal device determines whether to send a measurement report to the first access network device based on the signal quality threshold after compensation and the time threshold. This can reduce the occurrence of terminal devices disconnecting from the network due to insufficient network handover preparation time, thereby improving the communication quality of the terminal devices.

[0099] The above describes how terminal devices can determine the parameter value range corresponding to the target measurement value, and determine the threshold compensation amount based on the parameter value range.

[0100] In the second implementation method, the first access network device can configure a correspondence between parameter value ranges and threshold values ​​for the terminal device. This correspondence includes a correspondence between multiple parameter value ranges and multiple threshold values ​​of the reporting threshold. The terminal device determines the parameter value range in which the target parameter value is located based on the target parameter value and the correspondence, and determines the threshold value corresponding to the parameter value range as the threshold value of the reporting threshold.

[0101] For example, the target parameter value includes the target angle. The first access network device can send corresponding relationship configuration information to the terminal device. This corresponding relationship configuration information is used to configure the corresponding relationship as shown in Table 3. The first access network device configures three target angle intervals for the terminal device and the threshold value of the reporting threshold corresponding to each angle interval. For example, when the angle interval where the target angle is located is 0≤θ<θ2, the terminal device determines the threshold value of the reporting threshold to be x. th1 When the target angle falls within the angle range θ2 ≤ θ < θ3, the terminal device determines the reporting threshold value to be x. th2 When the target angle falls within the angle range of θ3 ≤ θ < 180°, the terminal device determines the reporting threshold value to be x. th3 , where x th1 <x th2 x th2 >x th3 .

[0104] For example, the target parameter value includes the target distance. The first access network device can send corresponding relationship configuration information to the terminal device. This corresponding relationship configuration information is used to configure the corresponding relationship as shown in Table 4. The first access network device configures four target distance intervals for the terminal device and the threshold value of the reporting threshold corresponding to each distance interval. For example, when the target distance is in the target distance interval d A <d≤d B The threshold value for determining the reporting threshold by the terminal device is x. th1 When the target distance is within the target distance interval d C <d≤d A The threshold value for determining the reporting threshold by the terminal device is x. th2 When the target distance is within the target distance interval d C <d≤d D The threshold value for determining the reporting threshold by the terminal device is x. th3 ; and, when the target distance interval is d D <d, the threshold value for the terminal device to determine the reporting threshold is x. th4 Among them, x th1 >x th2 >x th3 >x th4 .

[0107] According to the above scheme, the terminal device can determine the threshold value of the corresponding reporting threshold based on the relative positional relationship between the terminal device and the first access network device, as well as the correspondence between the relative positional relationship of the network configuration and the threshold value. This allows the terminal device to send measurement reports at appropriate times based on the network configuration, reducing the probability of ping-pong handover or disconnection from the network and improving the communication quality of the terminal device.
