[0049] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0050] The triggering method, apparatus, communication device, and communication system for neighbor cell measurement according to embodiments of this application are described below with reference to the accompanying drawings.

[0051] Figure 1 is a flowchart illustrating a triggering method for neighbor cell measurement applied to a terminal device, provided in an embodiment of this application.

[0052] As shown in Figure 1, the method includes the following steps:

[0053] Step 101: Receive first information from the network device. The first information carries the coverage shape parameters of the serving cell of the network device.

[0054] Network equipment can refer to portable network devices, such as satellite equipment.

[0055] Typically, when a terminal device is at the edge of a serving cell, it needs to acquire information about neighboring cells and measure neighboring cells. Based on this, coverage shape parameters can refer to parameters used to identify whether a terminal device is in an edge sub-region of the serving cell.

[0056] In one embodiment, the coverage shape parameter includes at least one of the following: a first shape parameter of the coverage area of ​​the serving cell; and a second shape parameter of a non-edge sub-region within the coverage area of ​​the serving cell. The non-edge sub-region can refer to the area within the coverage area other than the edge region.

[0057] The shape of the coverage area of ​​a serving cell varies, and the corresponding coverage shape parameters may differ. As an example and not a limitation, the shape of the coverage area of ​​a serving cell can refer to circular, quasi-circular, rectangular, and rectangular shapes, etc.

[0058] In one embodiment, when the coverage area of ​​the serving cell is a circular or near-circular area, the first shape parameter includes the radius of the coverage area; the second shape parameter includes the radius of the non-edge sub-region.

[0059] The radius of the non-edge sub-region can be configured independently of the radius of the coverage area. That is, if it is only necessary to determine whether the terminal device is in the non-edge sub-region, only the radius of the non-edge sub-region can be configured.

[0060] Please refer to Figure 2, which is a schematic diagram of a coverage area provided in an embodiment of this application. The figure shows a schematic diagram of a near-circular coverage area when a serving cell is deployed based on network equipment. In this case, the center point of the serving cell is the sub-satellite point. The area within the outer dashed line in the figure is the coverage area of ​​the serving cell. Outside this coverage area, the terminal device cannot obtain effective service from the serving cell. The area within the inner dashed line is the non-edge sub-region, and the area between the two dashed lines is the edge sub-region. R1 is the radius of the non-edge sub-region, and R2 is the radius of the coverage area. The sub-satellite point refers to the intersection of the line connecting the Earth's center and the network equipment on the Earth's surface. The terminal device can calculate the position of the sub-satellite point using satellite ephemeris data.

[0061] When multiple serving cells are deployed based on network equipment, replacing the nadir point in the diagram with the center point of the serving cell yields the radius of the coverage area and the radius of the non-edge sub-area. It should be noted that, when multiple serving cells are deployed based on network equipment, the first information can also carry the relative positional relationship between the center point and the nadir point of each serving cell, or it can carry the reference point of the center point of each serving cell relative to the ground projection. The terminal device can then calculate the trajectory of the serving cell center point based on satellite ephemeris.

[0062] In one embodiment, when the coverage area of ​​the serving cell is a rectangular or quasi-rectangular area, the first shape parameter includes at least one of the following: the length of the first side of the coverage area and the length of the second side of the coverage area; the second shape parameter includes at least one of the following: the length of the first side of the non-edge sub-area, the length of the second side of the non-edge sub-area, and the angle between the flight direction of the network device and the first or second side.

[0063] Please refer to Figure 3, which is a schematic diagram of another coverage area provided by an embodiment of this application. The figure shows a schematic diagram of a rectangular coverage area when a serving cell is deployed based on network devices. In the figure, the area within the black solid line is the coverage area of ​​the serving cell, the white area is the non-edge sub-area, and the shaded area is the edge sub-area. L1 and W1 are the lengths of the first and second sides of the non-edge sub-area, respectively. L2 and W2 are the lengths of the first and second sides of the coverage area, respectively. A is the angle between the flight direction of the network device and the first or second side. Here, the flight direction of the network device can also be understood as the direction of movement of the network device.

[0064] In one embodiment, the included angle included in the second shape parameter may also refer to the included angle between the target side and the equator or a certain line of latitude and longitude, wherein the target side refers to the first side or the second side.

[0065] Step 102: Based on the coverage shape parameters, determine whether to trigger the acquisition of neighboring cell information and neighboring cell measurement.

[0066] Coverage shape parameters are used to indicate the coverage area of ​​a serving cell, where coverage area can refer to the edge coverage area, non-edge coverage area, and off-coverage area of ​​the serving cell.

[0067] The terminal device can determine whether it is in the edge sub-region based on the coverage shape parameters. If the terminal device is in the edge sub-region, it can trigger the acquisition of neighboring cell information and neighboring cell measurement.

[0068] Based on the coverage shape parameters, the terminal device can accurately identify whether it is located in the edge sub-region, and then determine whether to trigger the acquisition of neighboring cell information and neighboring cell measurement, thus avoiding premature or delayed activation of neighboring cell measurement.

[0069] In this embodiment, first information is received from the network device, carrying the coverage shape parameters of the serving cell of the network device. Based on the coverage shape parameters, it is determined whether to trigger the acquisition of neighboring cell information and neighboring cell measurement. Therefore, the terminal device can directly perceive the coverage range of the serving cell of the network device based on the coverage shape parameters, and thus accurately identify whether to trigger the acquisition of neighboring cell information and neighboring cell measurement based on the coverage range of the serving cell. This avoids the terminal device receiving neighboring cell information at any location within the serving cell, and also avoids the network device sending neighboring cell information in non-edge sub-regions, thereby reducing the waste of related resources.

[0070] This embodiment provides another method for triggering neighbor cell measurement. Figure 4 is a flowchart illustrating a method for triggering neighbor cell measurement provided in this embodiment.

[0071] As shown in Figure 4, the method may include the following steps:

[0072] Step 401: Receive system information broadcast from the network device. The system information broadcast carries the first information.

[0073] In one embodiment, when the terminal device is in an idle state, it receives system information broadcasts from the network device.

[0074] In one embodiment, the terminal device can receive system information broadcasts from the network device when entering a serving cell.

[0075] In one embodiment, the terminal device can receive system information broadcasts from the network device after being powered on within the serving cell.

[0076] As an example and not a limitation, the first information may be contained in system information such as system information block (SIB)1, SIB2, or SIB19, where SIB19 includes satellite ephemeris.

[0077] Step 402: When the terminal device is in a connected state, it receives a reconfiguration message from the network device. The reconfiguration message carries the first information.

[0078] Neighbor cell measurement control in the connected state can be configured independently of the idle state. Based on this, the embodiments of this application also propose a method to obtain the first information from the reconfiguration message (RRC Reconfiguration), that is, the first information can also be included in the reconfiguration message.

[0079] Among them, the connected state can refer to the state where the terminal device is camped and performing a service, such as making a phone call or transmitting data; the idle state can refer to the state where the terminal device is camped but not performing a service, or the state of searching for networks before camping.

[0080] Step 403: Based on the coverage shape parameters, determine the sub-region where the terminal device is located within the coverage area of ​​the serving cell; if the sub-region is an edge sub-region, trigger the acquisition of neighboring cell information and neighboring cell measurement.

[0081] In one embodiment, regardless of whether the terminal device is in a connected state or an idle state, it can determine whether to trigger the acquisition of neighboring cell information and neighboring cell measurement based on the coverage shape parameters.

[0082] Taking a circular coverage area as an example, the distance between the terminal device and the center point of the serving cell, and the relationship between the radius of the non-edge sub-area and the radius of the coverage area, can be used to determine whether the terminal device is located in the edge sub-area.

[0083] Taking a rectangular coverage area as an example, the location coordinates of the terminal device and the coordinates of the center point of the serving cell can be converted to a coordinate system with the first side and the second side as the horizontal and vertical axes, respectively, to determine whether the sub-area where the terminal device is located is an edge sub-area.

[0084] When the sub-region where the terminal device is located is an edge sub-region, determine the acquisition of neighboring cell information and neighboring cell measurement.

[0085] As an example and not a limitation, neighbor cell related information can refer to system information configured in the serving cell regarding neighbor cell measurements, reselection, and satellite ephemeris of neighbor cells, such as the neighbor cell configuration information in SIB2, SIB3, SIB4, SIB5, and SIB19.

[0086] Step 404: Obtain neighbor cell information; perform neighbor cell measurement processing based on the neighbor cell information to obtain measurement results; and perform serving cell handover processing based on the measurement results.

[0087] In one embodiment, obtaining neighbor cell-related information includes: reading neighbor cell-related information from stored system information, or, in response to not finding neighbor cell-related information in stored system information, re-receiving system information broadcast from the network device and obtaining neighbor cell-related information from the system information.

[0088] When there are multiple neighboring cells, neighboring cell measurements can be performed based on the relevant information of each neighboring cell to obtain measurement results.

[0089] Based on the measurement results of each neighboring cell, the neighboring cell with better signal quality is selected for cell handover.

[0090] In this embodiment, a system information broadcast carrying first information is received from the network device; when the terminal device is in a connected state, a reconfiguration message carrying the first information is received from the network device; based on the coverage shape parameters, the sub-region where the terminal device is located within the coverage area of ​​the serving cell is determined; if the sub-region is an edge sub-region, neighbor cell related information acquisition and neighbor cell measurement are triggered; neighbor cell related information is acquired; based on the neighbor cell related information, neighbor cell measurement processing is performed to obtain the measurement results; based on the measurement results, serving cell handover processing is performed. Therefore, the terminal device can obtain the first information through different methods in different states.

[0091] This embodiment provides another method for triggering neighbor cell measurement. Figure 5 is a flowchart illustrating a method for triggering neighbor cell measurement provided in this embodiment.

[0092] When the terminal device is in a connected state, in addition to determining whether to trigger the acquisition of neighboring cell information and neighboring cell measurement based on the coverage shape parameters, this embodiment also proposes another way to determine whether to trigger the acquisition of neighboring cell information and neighboring cell measurement.

[0093] As shown in Figure 5, the method may include the following steps:

[0094] Step 501: When the terminal device is in a connected state, it receives second information from the network device. The second information carries a first distance threshold, which indicates the boundary value of the first distance between the terminal device and the center point of the neighboring cell.

[0095] In one embodiment, the second information can be configured in the reconfiguration message.

[0096] Step 502: Based on the first distance threshold, determine whether to trigger the acquisition of neighboring cell information and neighboring cell measurement.

[0097] Based on the relationship between the distance between the terminal device and the center point of the neighboring cell and the first distance threshold, it can be determined whether to trigger the acquisition of neighboring cell information and the measurement of the neighboring cell.

[0098] In one embodiment, determining whether to trigger the acquisition of neighboring cell information and neighboring cell measurement based on a first distance threshold includes: determining the distance between the terminal device and the center point of the neighboring cell; and determining to trigger the acquisition of neighboring cell information and neighboring cell measurement if the distance is less than or equal to the first distance threshold.

[0099] If the distance between the terminal device and the center point of the neighboring cell is less than or equal to the first distance threshold, it indicates that the terminal device is close to the neighboring cell. In this case, the acquisition of relevant information about the neighboring cell and the measurement of the neighboring cell can be triggered to maintain the continuity of the terminal device's services.

[0100] Because the near-far effect is not significant in satellite communication systems, using cell signal strength to determine cell coverage becomes inaccurate in related technologies. Since the movement trajectory and coverage area of ​​network devices are determined, using distance as the trigger condition for acquiring and measuring neighboring cell information is more accurate in satellite communication systems. Moreover, compared to signal strength measurement, determining whether to trigger neighboring cell information acquisition and measurement based on distance can save power consumption of terminal equipment.

[0101] In this embodiment, when the terminal device is in a connected state, it receives second information from the network device. The second information carries a first distance threshold, which indicates the boundary value of a first distance between the terminal device and the center point of a neighboring cell. Based on the first distance threshold, it is determined whether to trigger the acquisition of neighboring cell-related information and the measurement of neighboring cells. This application's method of determining whether to trigger the acquisition of neighboring cell-related information and the measurement of neighboring cells based on distance can save power consumption of the terminal device.

[0102] This embodiment provides another method for triggering neighbor cell measurement. Figure 6 is a flowchart illustrating a method for triggering neighbor cell measurement provided in this embodiment.

[0103] The determination of whether to trigger neighbor cell-related information acquisition and neighbor cell measurement is based on the distance between the terminal device and the center point of the neighbor cell. However, there may be situations where the distance between the terminal device and the center point of the neighbor cell is less than a first distance threshold, but the terminal device is still in a non-edge sub-region. To avoid this situation and improve the accuracy of the triggering timing of neighbor cell-related information acquisition and neighbor cell measurement, this embodiment also proposes another method for determining whether to trigger neighbor cell-related information acquisition and neighbor cell measurement, as shown in Figure 6. This method may include the following steps:

[0104] Step 601: When the terminal device is in a connected state, it receives third information from the network device. The third information carries a second distance threshold. The second distance threshold indicates the boundary value of the difference between the second distance and the first distance. The second distance is the distance between the terminal device and the center point of the serving cell, and the first distance is the distance between the terminal device and the center point of the neighboring cell.

[0105] In one embodiment, the third information can be configured in the reconfiguration message.

[0106] Step 602: Based on the second distance threshold, determine whether to trigger the acquisition of neighboring cell information and neighboring cell measurement.

[0107] In one embodiment, determining whether to trigger neighbor cell-related information acquisition and neighbor cell measurement based on a second distance threshold includes: determining a second distance between the terminal device and the center point of the serving cell; determining a first distance between the terminal device and the center point of a neighbor cell; and determining to trigger neighbor cell-related information acquisition and neighbor cell measurement if the difference between the second distance and the first distance is greater than or equal to the second distance threshold.

[0108] The difference between the second distance and the first distance can reflect not only the relative positional relationship between the terminal device and the serving cell, but also the positional relationship between the terminal device and neighboring cells. Therefore, determining whether to trigger the acquisition of neighboring cell information and neighboring cell measurement based on the difference between the second distance and the first distance can further improve the accuracy of the triggering timing of the acquisition of neighboring cell information and neighboring cell measurement.

[0109] In this embodiment, when the terminal device is in a connected state, it receives third information from the network device. This third information carries a second distance threshold, which indicates the boundary value of the difference between the second distance and the first distance. The second distance is the distance between the terminal device and the center point of the serving cell, and the first distance is the distance between the terminal device and the center point of a neighboring cell. Based on the second distance threshold, it is determined whether to trigger neighboring cell-related information acquisition and neighboring cell measurement. Therefore, this application can further improve the accuracy of the triggering timing for neighboring cell-related information acquisition and neighboring cell measurement.

[0110] This embodiment provides a method for rapid offline recovery. Figure 7 is a flowchart illustrating a method for rapid offline recovery provided in this embodiment.

[0111] As shown in Figure 7, the method may include the following steps:

[0112] Step 701: Determine whether the terminal device is located within the coverage area of ​​the serving cell based on the coverage shape parameters.

[0113] In satellite communication systems, the movement of terminal equipment and / or network equipment may cause the terminal equipment to leave the coverage area of ​​the serving cell. Therefore, in addition to determining whether to trigger the acquisition of neighboring cell information and neighboring cell measurement based on the coverage shape parameters, it is also necessary to determine whether the terminal equipment is located within the coverage area of ​​the serving cell based on the coverage shape parameters.

[0114] In one embodiment, determining whether a terminal device is located within the coverage area of ​​the serving cell is the same as determining whether a terminal device is located in the edge sub-region of the serving cell, and will not be described again here.

[0115] Step 702: When the terminal device is not located within the coverage area of ​​the serving cell, the signal strength measurement and evaluation processing of the serving cell is performed within M consecutive discontinuous reception (DRX) cycles, where M is less than the number N consecutive DRX cycles specified in the protocol for serving cell signal strength measurement and processing.

[0116] Once a terminal device leaves the coverage area of ​​the serving cell, it is meaningless to measure the serving cell again. Furthermore, since the movement direction of network devices is fixed, terminal devices that have left the coverage area of ​​the serving cell will not re-enter the serving cell in the short term. At this time, the measurement and search of neighboring cells should be started as soon as possible.

[0117] Based on this, this application proposes to reduce the number of consecutive DRX cycles in order to shorten the time for the terminal device to re-enter the network after disconnection and improve the user experience.

[0118] In one embodiment, N and M may be multiples of each other. As an example, and not a limitation, M can be determined using the following formula:

[0119] M = N / X

[0120] The value of X can be 2, 3, ...

[0121] Step 703: Based on the signal strength measurement and evaluation results, determine that the terminal device is not camped on a serving cell, and trigger neighbor cell measurement and neighbor cell search.

[0122] If the signal strength measurement and evaluation results indicate that the signal strength of the serving cell is less than the set signal strength for M consecutive DRX cycles, it is determined that the terminal device is not camped on the serving cell, and neighbor cell measurement and neighbor cell search are triggered in a timely manner to shorten the offline time of the terminal device.

[0123] In this embodiment, based on coverage shape parameters, it is determined whether the terminal device is located within the coverage area of ​​the serving cell. If the terminal device is not located within the coverage area of ​​the serving cell, signal strength measurement and evaluation processing of the serving cell is performed within M consecutive DRX cycles, where M is less than the number N consecutive DRX cycles specified in the protocol for serving cell signal strength measurement and evaluation. Based on the signal strength measurement and evaluation results, it is determined that the terminal device is not camping on the serving cell, and neighbor cell measurement and neighbor cell search are triggered. This application reduces the number of consecutive DRX cycles, which can shorten the time for the terminal device to re-camp after disconnection.

[0124] This embodiment provides a data transmission scheduling method. Figure 8 is a flowchart illustrating a data transmission scheduling method provided in this embodiment.

[0125] As shown in Figure 8, the method may include the following steps:

[0126] Step 801: When the terminal device is in a connected state, determine the movement trend of the terminal device based on the coverage shape parameters, the satellite ephemeris of the serving cell, and the current location of the terminal device.

[0127] Due to the movement of terminal devices and / or network devices, the sub-region where the terminal device is located may change from an "edge sub-region" to a "non-edge sub-region," and vice versa. To avoid data transmission lag that degrades user experience, this application proposes scheduling the transmission of data in the terminal device when the sub-region where the terminal device is located changes.

[0128] In order to schedule data transmission in a timely manner, the movement trend of terminal devices can be predicted based on coverage shape parameters, satellite ephemeris of the serving cell, and the current location of the terminal devices.

[0129] Step 802: When the mobility trend indicates that the terminal device will enter the edge sub-area of ​​the coverage area of ​​the serving cell, the non-real-time data in the terminal device is processed for advance transmission.

[0130] When a terminal device is moving from a non-edge sub-region to an edge sub-region, non-real-time data can be pre-scheduled to be transmitted before entering the edge sub-region. For example, non-real-time audio and video data can be pre-downloaded and buffered in the non-edge sub-region to avoid download stuttering in the edge sub-region and affecting the user experience.

[0131] Step 803: If the mobile trend indicates that the terminal device will enter a non-edge sub-area within the coverage area, pause the transmission of non-real-time data.

[0132] When a terminal device moves from an edge sub-region to a non-edge sub-region, the transmission of non-real-time data can be scheduled to be paused and resumed after entering the non-edge sub-region, providing users with a better service experience and saving channel resources.

[0133] In this embodiment, when the terminal device is in a connected state, the movement trend of the terminal device is determined based on the coverage shape parameters, the satellite ephemeris of the serving cell, and the current location of the terminal device. If the movement trend indicates that the terminal device will enter an edge sub-region within the coverage area of ​​the serving cell, non-real-time data in the terminal device is pre-transmitted. If the movement trend indicates that the terminal device will enter a non-edge sub-region within the coverage area, the transmission of non-real-time data is suspended. This application schedules the transmission of non-real-time data based on the terminal device's movement trend, which can concentrate data transmission in non-edge sub-regions as much as possible, improving user experience.

[0134] Please refer to Figure 9, which is a schematic diagram of a mobile scenario for a terminal device provided in an embodiment of this application. The serving cell in Figure 9 is roughly circular, i.e., a honeycomb hexagon. The serving cell consists of multiple wave positions, each represented by a small hexagon. White wave positions are non-edge wave positions, and gray wave positions are edge wave positions. According to the description of the foregoing embodiments of this application, the system information configuration corresponding to this serving cell is as follows:

[0135] (1) Send system information SIBx at the edge position according to the relevant 3rd generation partnership project (3GPP) technical standards.

[0136] (2) Do not transmit neighbor-related information in non-edge positions. Not transmitting neighbor-related information can mean not transmitting SIB2 to SIB5, and not transmitting neighbor-related configurations in SIB19.

[0137] (3) Add a coverage shape parameter cell to the SIB19 of the entire cell to carry the radius R1 of the non-edge sub-region and the radius R2 of the service cell coverage area. Among them, the wave position of the R1 trajectory, that is, the wave position on the inner dashed line in the figure, is also regarded as the edge wave position, so that when the terminal device moves from inside the R1 trajectory to outside the trajectory, it can receive the relevant information of the neighboring cell in a timely manner.

[0138] The terminal device movement scenario in this embodiment is the scenario where the terminal device reselects from the edge of the serving cell to enter the serving cell and then leaves the serving cell. In the figure, step1, step2, step3, and step4 represent the four positions of the terminal device in this movement scenario. The following describes the operations that the terminal device needs to perform at the aforementioned four positions, in conjunction with the content of the previous embodiment:

[0139] Step 1: When a terminal device in an idle state enters the serving cell and is located in the edge sub-region, it receives system information broadcasts, obtains all system information including information about neighboring cells, and retrieves R1 and R2 from SIB19 in the system information.

[0140] Step 2: Due to the movement of the terminal device and / or network device, the terminal device moves from position step 1 to position step 2. The terminal device determines the distance between its own position and the sub-satellite point. In response to the distance being less than R1, it determines that it is in a non-edge sub-region, closes the acquisition of neighbor cell related information and neighbor cell measurement, and stores the system information acquired at position step 1.

[0141] Step 3: Due to the movement of the terminal device and / or network device, the terminal device moves to position step 3. The terminal determines the distance between its own position and the sub-satellite point. In response to the distance being greater than R1, it determines that it is in the edge sub-region and starts to acquire neighboring cell related information and measure neighboring cells.

[0142] Step 4: Replace the serving cell by measuring neighboring cells. If reselection is not performed in time, the terminal device can determine the distance between its own location and the sub-satellite point. In response to the distance being greater than R2, it can promptly determine that it has left the coverage of the original serving cell and trigger the selection of a cell after disconnection based on the consecutive number M of DRX cycles.

[0143] Please refer to Figure 10, which is a schematic diagram of a terminal device movement scenario provided in an embodiment of this application. In this embodiment, the terminal device powers on and camps on the non-edge sub-area of ​​the serving cell, then moves to the edge sub-area of ​​the serving cell. Step 1 and Step 2 in the figure represent two positions of the terminal device in this movement scenario. The following describes the operations required for the terminal device to perform at the aforementioned four positions, in conjunction with the content of the foregoing embodiment:

[0144] Step 1: The terminal device is powered on at the location of the serving cell. It receives partial system information from the network device that does not contain information about neighboring cells. It obtains R1 and R2 from SIB19 in the system information and determines the distance between its own location and the sub-satellite point. In response to the distance being less than R1, it determines that it is in a non-edge sub-region and keeps neighboring cell measurement off.

[0145] Step 2: Due to the movement of the terminal device and / or network device, the terminal device moves to position step 2. The terminal device determines the distance between its own position and the sub-satellite point. In response to the distance being greater than R1, it determines that it is in the edge sub-region. Since the system message stored by the terminal device in step 1 does not contain neighbor cell information, the terminal device needs to re-receive system information from the network device and obtain neighbor cell information from the re-received system information, and start neighbor cell measurement.

[0146] Figure 11 is a flowchart illustrating a triggering method for neighbor cell measurement in a network device provided in an embodiment of this application.

[0147] As shown in Figure 11, the method includes the following steps:

[0148] Step 1101: Send first information to the terminal device. The first information carries the coverage shape parameters of the serving cell of the network device. The coverage shape parameters are used to determine whether to trigger the acquisition of neighboring cell related information and neighboring cell measurement.

[0149] In response to detecting that a terminal device is located in the serving cell, the network device can send first information to the terminal device.

[0150] The relevant content in step 1101 can be found in the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0151] In one embodiment, the coverage shape parameter includes at least one of the following: a first shape parameter of the coverage area of ​​the serving cell; and a second shape parameter of a non-edge sub-region within the coverage area of ​​the serving cell.

[0152] In one embodiment, the coverage area of ​​the serving cell is a circular area; the first shape parameter includes the radius of the coverage area; the second shape parameter includes the radius of the non-edge sub-region.

[0153] In one embodiment, the coverage area of ​​the serving cell is a rectangular area; the first shape parameter includes at least one of the following: the length of a first side of the coverage area and the length of a second side of the coverage area; the second shape parameter includes at least one of the following: the length of a first side of a non-edge sub-area, the length of a second side of a non-edge sub-area, and the angle between the flight direction of the network device and the first or second side.

[0154] In one embodiment, sending first information to a terminal device includes: sending a system information broadcast to the terminal device, wherein the system information broadcast carries the first information.

[0155] In one embodiment, sending first information to a terminal device includes: when the terminal device is in a connected state, sending a reconfiguration message to the terminal device, wherein the reconfiguration message carries the first information.

[0156] In one embodiment, the method further includes: when the terminal device is in a connected state, sending second information to the terminal device, the second information carrying a first distance threshold, the first distance threshold indicating the boundary value of a first distance between the terminal device and the center point of a neighboring cell; the first distance threshold is used to determine whether to trigger the acquisition of neighboring cell related information and neighboring cell measurement.

[0157] In one embodiment, the method further includes: when the terminal device is in a connected state, sending third information to the terminal device, the third information carrying a second distance threshold, the second distance threshold indicating the boundary value of the difference between the second distance and the first distance, the second distance being the distance between the terminal device and the center point of the serving cell, and the first distance being the distance between the terminal device and the center point of the neighboring cell; the second distance threshold is used to determine whether to trigger the acquisition of neighboring cell related information and neighboring cell measurement.

[0158] In one embodiment, the method further includes: determining an edge sub-region within the coverage area of ​​the serving cell based on coverage shape parameters; and sending neighbor cell-related information only to terminal devices within the edge sub-region. The neighbor cell-related information is used for mobility management.

[0159] In one embodiment, neighboring cell information may be included in the system information.

[0160] Terminal devices only need to perform neighbor cell measurements at the edge of the serving cell to ensure continuous coverage in dynamic scenarios. Based on this, this application proposes that if the terminal device is located in the edge sub-region of the serving cell, the system information sent by the network device to the terminal device can refer to the system information specified in the protocol, that is, the system information includes neighbor cell related information; if the terminal device is located in the non-edge sub-region of the serving cell, the system information sent by the network device to the terminal device may not include neighbor cell related information.

[0161] Compared to related technologies that require repeatedly transmitting all system information throughout the entire serving cell, this application only broadcasts system information, including information related to neighboring cells, in the edge sub-region, which significantly reduces the area where system information is repeatedly transmitted, saves system resources and power consumption, and avoids unnecessary waste of system resources.

[0162] In this embodiment, first information is sent to the terminal device. This first information carries the coverage shape parameters of the serving cell of the network device. The coverage shape parameters are used to determine whether to trigger neighbor cell-related information acquisition and neighbor cell measurement. Sending the first information carrying the coverage shape parameters to the terminal device allows the terminal device to directly perceive the coverage range of the serving cell of the network device based on these parameters. This enables the terminal device to accurately determine whether to trigger neighbor cell-related information acquisition and neighbor cell measurement based on the coverage range of the serving cell. This avoids the terminal device receiving neighbor cell-related information at any location within the serving cell and also avoids the network device sending neighbor cell-related information in non-edge sub-regions, thereby reducing the waste of relevant resources.

[0163] To implement the above embodiments, this application also proposes a triggering device for neighbor cell measurement, which is applied to a terminal device.
