Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communications, and in particular, to a method and system for downloading files. Background Art

[0002] When the existing network management protocol (Tr069) is applied in the ground network, the communication between the network management and the equipment (fixed transmission network, such as optical fiber, etc.) is guaranteed compared to the communication between the satellite and the ground, and is available almost around the clock. There is little need to worry about whether the file transfer can be successfully completed. Even if there is an occasional network interruption that prevents the transmission from being completed, the ground network management center can ensure the completion of the file transfer by re-initiating the download process.

[0003] When the network management protocol is adapted for inter-satellite equipment, due to the inter-satellite link's inter-satellite link availability, instability, and short available transmission time slots, there's a high probability that the link will be disconnected before the download is complete, resulting in a download failure. This requires the ground network management center to re-initiate the download command, wasting available transmission time slots and reducing file download efficiency. If the file's required transmission time exceeds the maximum available transmission time slot, the file will remain undownloaded, potentially preventing critical processes like software upgrades from completing.

[0004] There is currently no effective solution to the above problems. Summary of the Invention

[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and in combination with embodiments.

[0030] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0031] The method embodiments provided in the embodiments of the present application can be executed in a satellite-borne device, which can be a terminal device deployed on a satellite, or a computer terminal or a similar computing device.

[0032] Figure 1 FIG. 1 is a hardware structure block diagram of a satellite-borne device for a method of downloading files according to an embodiment of the present invention. Figure 1 As shown, the onboard equipment may include one or more ( Figure 1 Only one is shown) a processor 102 (the processor 102 may include but is not limited to a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data. The above-mentioned onboard equipment may also include a transmission device 106 for communication functions and an input and output device 108. It will be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above-mentioned satellite-borne equipment. For example, the satellite-borne equipment may also include Figure 1More or fewer components than shown, or with Figure 1 Different configurations shown.

[0033] The memory 104 can be used to store computer programs, such as software programs and modules of application software, such as the computer program corresponding to the method for downloading files in the embodiment of the present invention. The processor 102 executes the computer programs stored in the memory 104 to execute various functional applications and data processing, thereby implementing the above-mentioned method. The memory 104 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include memory remotely located relative to the processor 102, and these remote memories may be connected to onboard equipment via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0034] Transmission device 106 is used to receive or transmit data via a network. A specific example of such a network may include a wireless network provided by the onboard equipment's communications provider. In one embodiment, transmission device 106 includes a network interface controller (NIC), which can be connected to other network devices via a base station to enable communication with the Internet. In another embodiment, transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0035] In this embodiment, a method for downloading files running on the above-mentioned satellite-borne device is provided. Figure 2 is a flow chart of a method for downloading files according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0036] Step S202: Receive a download signaling, wherein the download signaling includes a first field and a second field, the first field is used to indicate whether segmented downloading of the target file is supported, and the second field is used to indicate a deadline for downloading the target file;

[0037] The download signaling is a Download signaling message, and the first field is a ResumableDownload field, which indicates whether segmented downloading of the target file is supported, for example, whether the file server on the satellite-borne device network side supports segmented downloading of the target file.

[0038] The second field is the ExpiredTime field, which indicates the deadline for downloading the target file.

[0039] This application adds a new first field and a new second field to the existing download signaling.

[0040] The first field is used to notify the onboard equipment to deploy the segmented download target file.

[0041] The first field can also be used to indicate whether the file server of the satellite-borne device in the ground network management center supports segmented downloading. If segmented downloading is supported, the satellite-borne device downloads the file server in segments.

[0042] The second field instructs the onboard device to report a download failure to the ground network management center if the download is not completed before the specified deadline. This field ensures consistent monitoring of the download process by the ground network management center and the onboard device. This solution minimizes modifications to existing protocols while maintaining compatibility with existing protocols. Table 1 below shows the fields in the modified Download signaling message.

[0043] Table 1

[0044]

[0045] Step S204: If the segmented download is supported, download the target file in segments.

[0046] In an exemplary embodiment, when the value of the first field is true or 1, the target file is downloaded in segments.

[0047] In an exemplary embodiment, downloading the target file in segments includes: if the deadline is not reached, downloading in segments via a satellite-to-ground link to obtain N file segments, where N is an integer; and splicing the N file segments to obtain the target file.

[0048] In an exemplary embodiment, after obtaining N file segments through segmented downloading via the satellite-to-ground link, the N file segments are saved.

[0049] The step of obtaining N file segments by segmented downloading via the satellite-to-ground link includes: obtaining the N file segments by segmented downloading during each available time slot of the satellite-to-ground link.

[0050] For example, the i-th file segment is downloaded at the i-th time segment available in the satellite-to-ground link, where i is an integer less than or equal to N; and the i-th file segment is saved, where the N file segments include the i-th file segment.

[0051] After downloading the i-th file segment in the i-th time slot available on the satellite-to-ground link, the method further includes: disconnecting the satellite-to-ground link and pausing downloading of the target file; detecting whether there is an undownloaded file; if there is an undownloaded file and the deadline has not been reached, downloading the i+1-th file segment in the i+1-th time slot available on the satellite-to-ground link, wherein the N file segments include the i+1-th file segment.

[0052] In an exemplary embodiment, the method further includes: when the deadline is reached and there are files that have not been downloaded, sending a download failure message to the ground network management center; when the target file is downloaded before the deadline, sending a download completion message to the ground network management center.

[0053] According to another embodiment of the present invention, a method for downloading files is provided, which is applied to a ground network management center, and includes: sending a download signaling, the download signaling including a first field and a second field, the first field being used to indicate whether segmented downloading of the target file is supported, and the second field being used to indicate a deadline for downloading the target file; receiving a download failure message sent by the satellite-borne device, wherein the download failure message is used to indicate that the satellite-borne device has not completed downloading the target file before the deadline; or, receiving a download completion message sent by the satellite-borne device, wherein the download completion message is used to indicate that the satellite-borne device has completed downloading the target file before the deadline.

[0054] like Figure 3 The diagram shows the information exchange between the ground network management center and the onboard device. The ground network management center adds the first field (ResumableDownload field) to the download signaling, instructing the onboard device to download the target file in segments. The second field (ExpiredTime field) is added to inform the onboard device that if the onboard device does not receive a transmission completion signaling or a download failure signaling before the expiration time (ExpiredTime time, for example, 2025-12-30T12:00:00 shown in the figure), the ground network management center considers the download to have failed.

[0055] After the onboard device receives a download signaling (such as a software upgrade package) from the ground network management center, if the file server on the onboard device network management side supports segmented file transmission and the signaling contains the first field (ResumableDownload field) and the value is true or 1, the onboard device uses the segmented transmission protocol to download the file. During each available time slice of the satellite-ground link, the onboard device saves the successfully downloaded file segments and finally completes the download of the entire target file by splicing the files.

[0056] If all file segments are not downloaded by the ExpiredTime, a download failure message is sent to the ground network management system. If all file segments are downloaded by the ExpiredTime, a download completion message is sent to the ground network management system. If the ResumableDownload value is false or 0, the onboard device downloads using the normal transport protocol and ignores the ExpiredTime field.

[0057] In an exemplary embodiment, the expiration time of the ExpiredTime field may be set according to actual conditions, and may also be set to:

[0058] ExpiredTime = current time + file transfer period;

[0059] The file transfer period can be set according to actual conditions.

[0060] Compared with the existing TR069 protocol, this application has the following advantages when used for file transfer between satellite and ground: it does not waste every available transmission time slice, thereby improving the utilization rate of available transmission time slices between satellite and ground. To avoid the problem that large files may never be successfully downloaded, the ResumableDownload field is used to instruct the satellite-borne device to download in segments. The ExpiredTime field is used to align the monitoring consistency of the download process between the ground network management center and the satellite-borne device, thus avoiding the situation where the ground network management center believes that the download has timed out and failed, but the satellite-borne device continues to download.

[0061] Through the description of the above embodiments, those skilled in the art will clearly understand that the methods according to the above embodiments can be implemented using software plus the necessary general-purpose hardware platform. Of course, hardware can also be used, but in many cases the former is a more preferred embodiment.
