Technical Field

[0001] This invention belongs to the field of communication technology, and in particular relates to a method, device, storage medium and program product for updating spectrum parameters. Background Technology

[0002] In NTN networks, satellite-based base stations are not stationary; they move periodically along specific orbits with satellites. During this movement, the antenna coverage area spans multiple countries and regions globally, with differences in spectrum usage across these regions. Currently, base station beam resources are limited and are typically configured with fixed frequency bands, frequencies, and bandwidths, making real-time and flexible configuration switching impossible. Therefore, when a base station moves to a different area, it may cause terminals in that area to be unable to access the network. Summary of the Invention

[0003] In view of the problems existing in the prior art, the present invention provides a method, device, storage medium and program product for updating spectrum parameters, which at least partially solves the problem that terminals cannot access the network when the satellite base station moves to other areas.

[0006] Based on the real-time location information and operating status information, the current coverage information of the satellite base station is calculated in real time;

[0007] The current coverage information is compared with a preset coverage spectrum relationship table, which defines the mapping relationship between different geographical coverage areas and spectrum parameters.

[0008] When the comparison result meets the preset triggering conditions, the cell spectrum parameter update process is triggered to update the cell spectrum parameters of the satellite base station to the spectrum parameters corresponding to the current coverage information.

[0009] Optionally, obtaining the real-time location information and operational status information of the satellite-borne base station includes:

[0010] The satellite-borne base station receives navigation messages broadcast by navigation satellites and ephemeris information uploaded by the ground control center;

[0016] Optionally, the triggering conditions when the comparison result meets the preset triggering conditions include:

[0017] The current coverage information has exceeded the threshold coverage range corresponding to the currently effective spectrum parameter in the relation table, and the current coverage information is mapped to only one spectrum parameter in the relation table.

[0018] Optionally, the process of triggering cell spectrum parameter updates includes:

[0019] Determine whether there are active users in the cell of the satellite-borne base station;

[0041] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0042] like Figure 1 As shown, this embodiment discloses a method for updating spectrum parameters, applied to a spaceborne base station in a low-Earth orbit satellite communication system. The method includes:

[0043] Obtain real-time location and operational status information of the satellite-borne base station;

[0044] Based on the real-time location information and operating status information, the current coverage information of the satellite base station is calculated in real time;

[0045] The current coverage information is compared with a preset coverage spectrum relationship table, which defines the mapping relationship between different geographical coverage areas and spectrum parameters.

[0046] When the comparison result meets the preset triggering conditions, the cell spectrum parameter update process is triggered to update the cell spectrum parameters of the satellite base station to the spectrum parameters corresponding to the current coverage information.

[0047] Optionally, obtaining the real-time location information and operational status information of the satellite-borne base station includes:

[0048] The satellite-borne base station receives navigation messages broadcast by navigation satellites and ephemeris information uploaded by the ground control center;

[0049] The navigation message and the ephemeris information are fused together, and the real-time position coordinates and operating speed of the satellite base station are calculated based on the fused information.

[0050] Specifically, the low-Earth orbit satellite base station in orbit simultaneously receives navigation messages broadcast by navigation satellites (such as BeiDou / GPS) and ephemeris information uploaded by the ground operation and control center through the telemetry and control link. The two are then combined to calculate the base station's real-time precise location coordinates and operating speed.

[0051] Optionally, the operational status information includes at least one of satellite attitude, beam pointing parameters, and antenna transmit power.

[0052] Optionally, the step of calculating the current coverage information of the satellite-borne base station in real time based on the real-time location information and operating status information includes:

[0053] Check the status of the spectrum parameter dynamic reconfiguration switch in the satellite base station;

[0054] The current coverage information of the satellite base station is calculated only when the dynamic reconfiguration switch for the spectrum parameters is turned on.

[0055] Specifically, the low-orbit satellite base station itself adds a table showing the relationship between the coverage area of ​​the antennas in orbit and the spectrum parameters (frequency point, frequency band, bandwidth) (i.e., the coverage area spectrum relationship table, or simply the relationship table), as well as a switch for dynamic reconfiguration of spectrum parameters.

[0056] The relationship table can refer to the Radio Regulations of the International Telecommunication Union (ITU) to map and associate the spectrum information used in various regions of the world with specific geographical coordinates.

[0057] If the dynamic reconfiguration switch for spectrum parameters is set to off, the cell spectrum and bandwidth-related parameters will not change with the base station's location. If the dynamic reconfiguration switch for spectrum parameters is set to on, the base station's OM module will periodically calculate real-time cell coverage information by combining satellite attitude, beam pointing, transmit power parameters, and base station coordinates and velocity. The base station adds a dynamic reconfiguration switch for spectrum parameters, which controls whether the base station dynamically configures spectrum parameters. The base station's OM module calculates the cell coverage area in real time, combining navigation messages broadcast by navigation satellites (such as BeiDou / GPS), ephemeris information, beam pointing parameters, satellite attitude, and antenna transmit power information recorded by the ground control center through the telemetry and control link, to calculate the antenna's coverage area in real time, presenting it in coordinate form.

[0058] Optionally, the triggering conditions when the comparison result meets the preset triggering conditions include:

[0059] The current coverage information has exceeded the threshold coverage range corresponding to the currently effective spectrum parameter in the relation table, and the current coverage information is mapped to only one spectrum parameter in the relation table.

[0060] Specifically, the real-time cell coverage information is compared with the relationship table. If the current coverage of the cell is within the threshold range of the spectrum parameters in the relationship table, the cell spectrum parameter configuration remains unchanged. If the current coverage of the cell exceeds the threshold range of the spectrum parameters in the relationship table and only one spectrum parameter is mapped, the cell spectrum parameter update process is triggered.

[0061] Optionally, the process of triggering cell spectrum parameter updates includes:

[0062] Determine whether there are active users in the cell of the satellite-borne base station;

[0063] If there are active users, wait for the user to disconnect or execute a switchover process to migrate the user to a neighboring area;

[0064] After confirming that there are no active users in the cell, perform a spectrum parameter update operation.

[0065] Optionally, the spectral parameter update operation includes:

[0066] Back up the current cell configuration file;

[0067] Update the cell spectrum parameters to the spectrum parameters corresponding to the current coverage information;

[0068] After the update is successful, reactivate the community.

[0069] Specific examples Figure 2As shown, the cell spectrum parameter update process first requires determining whether there are users in the cell. If users exist, the user is switched to a neighboring cell through a handover process, or the wireless air interface signal gradually deteriorates as the base station operates in orbit, causing the user to drop the connection. When no users are found in the cell, the current configuration file is backed up so that the configuration can be restored through the backup file in case of process abnormalities. Finally, the cell spectrum parameters are updated, and the cell is activated normally.

[0070] This embodiment provides a method for flexibly and adaptively reconfiguring frequency points, frequency bands, and bandwidths during the on-orbit operation of a low-Earth orbit satellite base station. First, the onboard base station adds a table relating coverage area to spectrum and a dynamic spectrum parameter reconfiguration switch. When this switch is turned on, the base station receives ephemeris information from the ground control center and navigation messages from the satellite, fuses them to generate high-precision position coordinate information, and simultaneously combines beam pointing, transmit power parameters, and satellite attitude information to calculate the area information covered by the base station in real time. This information is compared with the relational table to determine whether a cell spectrum parameter update process has been triggered. If the triggering conditions are met, the cell is reconfigured to the authorized and compliant frequency points, frequency bands, and bandwidth parameters for that area, enabling terminals within the corresponding coverage area to access the network normally.
