[0080] The satellite constellation deployment in the NTN network can be a near-polar orbit constellation (Walker-star constellation) or an inclined circular orbit constellation (Walker-star-Delta constellation). Regardless of whether the satellite deployment method of the near-polar orbit constellation or the inclined circular orbit constellation is adopted, in order to ensure continuous coverage of the equatorial region, the number of orbital planes needs to be sufficient. However, this makes the orbital planes in the middle and high latitudes of the earth denser, and the satellite coverage range will overlap. This coverage overlap is aggravated with increasing latitude, which will cause signal interference between satellites. A simple way to deal with it is to shut down some satellites in the coverage overlap area in the middle and high latitudes to reduce coverage overlap and thus reduce signal interference. However, this method may have coverage holes, and it is impossible to achieve global seamless coverage, and some terminals cannot get network communication services.
[0081] In response to the problem of overlapping satellite coverage, the present application proposes that the service satellite can obtain the measurement results of the signal quality of the neighboring cell in the service cell by the terminal, so as to negotiate with the neighboring satellite that manages the neighboring cell to adjust the cell coverage. This can reduce the signal interference of adjacent network devices or reduce network coverage loopholes, and improve the communication quality of the terminal.

This allows the first network device to compare the signal quality of the first cell and the signal quality of the second cell measured by the terminal, determine whether there is interference between the signals of the two cells, and whether it is necessary to adjust the coverage of the first cell, or notify the second network device that manages the second cell to adjust the coverage of the second cell. However, the present application is not limited to this, and the terminal can also report the signal quality of the first cell to the first network device through other information.
[0091] In another implementation, the first information includes a signal quality difference between a signal quality of the second cell and a signal quality of the first cell.
[0092] That is, the terminal notifies the first network device of the signal quality of the second cell by means of the difference in signal quality between the second cell and the first cell contained in the first information. The first network device can determine the difference between the signal quality of the second cell and the signal quality of the first cell based on the first information.
[0093] Specifically, the first information may indicate whether the signal quality of the first cell is greater than, less than, or equal to the signal quality of the first cell, and indicate the signal quality difference between the signal quality of the first cell and the signal quality of the second cell. That is, the terminal indicates through the first information whether the signal quality of the first cell is worse, better, or the same as the signal quality of the second cell, and indicates the size of the difference.
[0094] In one implementation, the first network device receives at least one first information from at least one terminal within a first duration, where the first duration is a period duration of a neighboring cell signal quality detection period of the first network device.
[0095] For example, the first network device may count the signal quality of the second cell measured by the terminal in the first cell in each period according to the neighboring cell signal quality detection period, so as to determine whether the cell coverage needs to be adjusted.
[0096] S402: The first network device sends second information to the second network device according to at least one first information, where the second information is used to instruct the second network device to adjust the coverage of the second cell.
[0097] Correspondingly, the second network device receives the second information from the first network device. Specifically, it may include but not be limited to the following method 1 and method 2.
[0098] In a first approach, the first network device determines whether the second network device needs to adjust the coverage of the second cell according to at least one first information from a terminal in the first cell, thereby sending second information to the second network device.
[0099] The first network device may determine the average difference in signal quality between the signal quality of the second cell and the signal quality of the first cell according to the acquired at least one first information, and send second information to the second network device according to the average difference in signal quality.
[0100] For example, the first information includes the signal quality of the second cell, and the first network device can obtain the signal quality of the first cell measured by the at least one terminal through the first information or other information from the at least one terminal. The first network device can determine the average signal quality of the second cell based on the signal quality of the second cell measured by the at least one terminal, and determine the average signal quality of the first cell based on the signal quality of the second cell measured by the at least one terminal. Furthermore, the first network device can determine the average difference in signal quality between the average signal quality of the second cell and the average signal quality of the first cell. The first network device can determine whether the second network device needs to adjust the coverage of the second cell to reduce signal interference based on the average difference in signal quality.
[0101] For another example, the first information may include a signal quality difference between the signal quality of the second cell and the signal quality of the first cell, and the first information specifically indicates a magnitude relationship between the signal quality of the second cell and the signal quality of the first cell. The first network device may determine an average signal quality difference between the signal quality of the second cell and the signal quality of the first cell based on at least one first information from at least one terminal, thereby determining whether the second network device needs to adjust the coverage of the second cell.
[0102] In one implementation, when the average signal quality of the second cell is greater than the average signal quality of the first cell, and the difference in average signal quality is greater than a first threshold, the first network device determines to notify the second network device to reduce the coverage of the second cell, and the second information is specifically used to instruct the second network device to reduce the coverage of the second cell. Alternatively, when the average signal quality of the second cell is less than the average signal quality of the first cell, and the difference in average signal quality is greater than a second threshold, it is determined to notify the second network device to increase the coverage of the second cell, and the second information is specifically used to instruct the second network device to increase the coverage of the second cell. Otherwise, the first network device determines to keep the coverage of the second cell unchanged.
[0103] For example, the first network device determines, based on at least one first information, that the signal quality of the second cell is greater than the signal quality of the first cell, such as that the average signal quality of the second cell is greater than the average signal quality of the first cell, and the average difference in signal quality is greater than a first threshold. The first network device may determine that the signal interference between the first cell and the second cell is large, and therefore, the first network device may send second information to the second network device, and the second indication information in the second information may instruct the second network device to reduce the coverage of the second cell.
[0104] If the average signal quality of the second cell is greater than the average signal quality of the first cell, and the average difference in signal quality is less than or equal to the first threshold, the first network device may consider that the signal interference between the first cell and the second cell is small, and therefore there is no need to adjust the coverage of the second cell, and the first network device may determine to keep the coverage of the second cell unchanged.
[0105] For another example, the first network device determines, based on at least one first information, that the signal quality of the second cell is lower than the signal quality of the first cell, such as the average signal quality of the second cell is lower than the average signal quality of the first cell, and the average difference in signal quality is greater than a second threshold. The first network device may believe that there may be a coverage hole between the first cell and the second cell, and the terminal may not be able to switch normally to maintain communication continuity. Therefore, the first network device may send a second information to the second network device, and the second indication information in the second information may instruct the second network device to increase the coverage of the second cell.
[0106] If the average signal quality of the second cell is less than the average signal quality of the first cell, and the average difference in signal quality is less than or equal to the second threshold, the first network device may consider that the signal interference between the first cell and the second cell is small and there is no coverage hole, so there is no need to adjust the coverage range of the second cell, and the first network device may determine to keep the coverage range of the second cell unchanged.
[0107] In one implementation, the second information may include second indication information, where the second indication information is used to indicate one of the following ways of adjusting the coverage of the second cell:
[0108] Increase the coverage, decrease the coverage, maintain the coverage, or turn off part or all of the coverage of the second cell.
[0109] In one example, the second information may include at least one first information from the terminal obtained by the first network device. The second network device may increase, decrease or maintain the coverage of the second cell, or close part or all of the coverage of the second cell according to the at least one first information and the second indication information.
[0110] In another example, the second information may further include third indication information, where the third indication information is used to indicate a parameter of the coverage of the second cell, or a change in a parameter of the coverage.
[0111] Exemplarily, the parameters of the coverage range may include one or more of the following:
[0112] The off-axis angle of the coverage edge, the elevation angle of the coverage edge, the coverage radius, the side length of the coverage edge, or the coverage area.
[0113] If the second cell is a circular coverage, the third indication information may indicate one or more coverage parameters of the off-axis angle, elevation angle or coverage radius of the coverage edge point, or the change amount of one or more coverage parameters. Alternatively, if the second cell is a rectangular coverage, the third indication information may indicate the off-axis angle and / or side length of the coverage edge of the coverage of the second cell, or the change amount of the off-axis angle of the coverage edge and / or the change amount of the side length. Alternatively, the third indication information may indicate the coverage area of the second cell or the change amount of the coverage area.
[0114] The second network device increases, decreases or maintains the coverage of the second cell, or shuts down part or all of the coverage of the second cell according to the second indication information and the third indication information in the second information.
[0115] Optionally, the second information may specifically instruct the second network device to adjust the coverage corresponding to the reference signal of the second cell, and the second information may include information of the reference signal. Alternatively, the second information may specifically instruct the second network device to adjust the coverage of the beam of the second cell, and the second information may include information of the beam of the second cell.
[0116] For example, the second network device may notify the first network device of one or more reference signals (or beams) of the second cell that is adjacent to or overlaps with the coverage of the first cell. The first network device may configure the terminal in the first cell to measure the signal quality of the one or more reference signals (or beams), and the first information specifically includes the signal quality of the one or more reference signals (or beams). The first network device sends second information to the second network device based on at least one first information of at least one terminal, and the second information may include an identifier of the reference signal (or beam) of the second cell. In one embodiment, the second information also includes the at least one first information, and the second network device may increase, decrease or maintain the coverage of the one or more reference signals (or beams) based on the at least one first information. In another embodiment, the second information also includes third indication information, and the third indication information specifically indicates the parameter of the coverage of the reference signal (or beam) or the change in the parameter, and the second network device may adjust the coverage of the reference signal (or beam) based on the third indication information.
[0117] For example, if both the first network device and the second network device are satellites, the second information may be referred to as satellite coverage information, such as the second information may be recorded as SatCoverageInfo. The format of the second information may be expressed as follows:
[0118]
[0119] Among them, the second information may include satellite identification information, such as the above-mentioned Satindex. The satellite identification information is used to indicate the physical cell identifier (PCI) of the second cell, that is, the above-mentioned PCI, or, a satellite can manage a cell, then the satellite identification information can indicate the identification of the second network device, such as the above-mentioned PCI can be replaced by Satindex. The second information may also include beam identification information, such as the above-mentioned Beamindex, and the beam identification information is used to indicate the identification of the beam whose coverage needs to be adjusted, such as the beam identification information indicates the identification of one or more beams, that is, the above-mentioned Beam-index. Alternatively, the beam identification information can be replaced with reference signal identification information, such as RSindex, and the reference signal identification information can indicate a synchronization signal block (SSB) identification, such as SSB-index and / or a reference signal identification, such as the reference signal identification can be recorded as RS-index, or the reference signal can be a channel state information reference signal (CSI-RS), and the reference signal identification can be recorded as CSI-RS-index. The coverage information, namely the coverageinfo, may include but is not limited to one or more of the at least one first information, the second indication information or the third indication information.
[0120] In another implementation, the second information may include third indication information for indicating parameters of the coverage of the second cell, but does not include the second indication information. The first network device may adjust the coverage of the second cell according to the parameters of the coverage indicated by the third indication information.
[0121] The above describes the first method provided by the embodiment of the present application. The first network device can determine to notify the second network device through the second information to increase, decrease, maintain or close part or all of the coverage of the second cell based on the measurement result of the terminal on the second cell collected in the first cell. Or the first network device can determine the parameters of the coverage notified through the second information based on the measurement result of the terminal on the second cell collected in the first cell, so that the second network device adjusts the coverage of the second cell based on the adjustment method of the coverage of the second cell determined by the first network device.
[0122] Optionally, in this method one, the first network device can determine the adjustment method of the coverage of the first cell and the second cell based on the at least one first information, so as to reduce the signal interference between the first cell and the second cell or reduce the coverage loophole problem. For example, the first network device can determine to increase the coverage of the first cell based on the measurement result fed back by the terminal, and notify the second network device to reduce, maintain the coverage of the second cell, or close part or all of the coverage through the second information. Or the first network device can determine to reduce the coverage of the first cell based on the measurement result fed back by the terminal, and notify the second network device to increase or maintain the coverage of the second cell through the second information, etc., and this application does not limit this.
[0123] The second method provided in the embodiment of the present application is introduced below.
[0124] In a second mode, after the first network device obtains at least one first information from at least one terminal, the first network device sends second information to the second network device, where the second information includes the at least one first information. The second network device adjusts the coverage of the second cell according to the at least one second information in the second information.
[0125] In this manner, the first network device collects first information of terminals in the first cell, obtains measurement results of signal quality of the second cell by the terminals in the first cell, and sends the information to the second network device through second information. The second network device determines whether to adjust the coverage of the second cell and how to adjust the coverage of the second cell based on the measurement results of signal quality of the second cell by the terminals in the first cell, such as increasing, decreasing, maintaining the coverage of the second cell, or closing part or all of the coverage of the second cell.
[0126] In an implementation manner, after receiving the second information, the second network device may send fourth information to the first network device, where the fourth information is used to indicate that the coverage of the second cell has been adjusted.
[0127] The fourth information may indicate the result of adjusting the second cell. For example, the fourth information may indicate whether the second network device increases, decreases, or maintains the coverage of the second cell, or closes part or all of the coverage of the second cell. And / or, the fourth information may indicate the coverage parameter or the change amount of the coverage parameter after the second network device adjusts the coverage of the second cell. The first network device may determine the result of adjusting the coverage of the second cell by the second network device according to the fourth information.
[0128] Optionally, after the first network device determines the adjustment result of the second network device on the coverage of the second cell, it can further adjust the coverage of the first cell to reduce signal interference between the first cell and the second cell, or reduce network coverage loopholes, thereby ensuring the communication quality of the terminal in the first cell.
[0129] According to the above scheme, the network device can obtain the measurement result of the signal quality of the neighboring cell by the terminal in the serving cell, and negotiate with the neighboring network device that manages the neighboring cell to adjust the cell coverage. It can reduce the signal interference of the neighboring network device or reduce the network coverage loopholes, thereby ensuring the communication quality of the terminal.
[0130] exist Figure 4 In one implementation of the illustrated embodiment, the first information may indicate the signal quality of multiple neighboring cells of the first cell measured by the terminal. The first network device receives multiple first information from multiple terminals within a first time period, and the first time period is the period length of the neighboring cell signal quality detection period of the first network device. The first network device may determine the average number N of neighboring cells contained in the multiple first information, the average signal quality Q of each neighboring cell, and the average signal quality Q of each neighboring cell. N The first network device may also determine an average signal quality Q of the first cell based on the plurality of first information or other information from the plurality of terminals. S .
[0131] The average data volume N in the neighboring cell is less than the allowed data volume N of the neighboring cell. th In the case of the first network device, the first network device may determine whether the coverage range of the neighboring cell needs to be adjusted according to the following judgment method:
[0132] If the average signal quality Q of the multiple neighboring cells N The maximum average signal quality Q Nmax is greater than the average signal quality Qs of the first cell, and Q Nmax -Qs≥Q th, the first network device may determine to reduce the coverage of the neighboring cells other than the neighboring cell with the highest average signal quality among the multiple neighboring cells, and the first network device may notify the network device corresponding to the neighboring cell whose coverage needs to be reduced through the second information. Otherwise, the first network device may determine that the coverage of the first cell and the multiple neighboring cells does not need to be adjusted.
[0133] The average data volume N in the neighboring cell is greater than or equal to the allowed data volume N of the neighboring cell. th In the case of the first network device, the first network device may determine whether the coverage range of the neighboring cell needs to be adjusted according to the following judgment method:
[0134] If the average signal quality Q of the multiple neighboring cells N The maximum average signal quality Q Nmax is greater than the average signal quality Qs of the first cell, and Q Nmax -Qs≥Q th , the first network device may determine to reduce the coverage of the neighboring cells other than the neighboring cell with the highest average signal quality among the multiple neighboring cells, and the first network device may notify the network device corresponding to the neighboring cell whose coverage needs to be reduced through the second information. Otherwise, the first network device may determine to reduce the coverage of each neighboring cell among the multiple neighboring cells, and the first network device may notify the network device corresponding to each neighboring cell among the multiple neighboring cells through the second information.
[0135] According to the above scheme, the network device can obtain the measurement results of the signal quality of multiple neighboring cells in the service cell by the terminal, and negotiate with the neighboring satellites that manage the neighboring cells to adjust the cell coverage. It can reduce the signal interference of adjacent network devices or reduce network coverage loopholes, thereby ensuring the communication quality of the terminal.
