Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Fig. 1 shows a communication diagram of a satellite communication link. The satellite communication link includes a satellite, a ground station, a control center station, and a mobile terminal. In the satellite communication link, communication between mobile users or between a mobile user and a fixed user can be realized by transmitting signals through a satellite as a relay station.

As shown in fig. 1, the control center is provided with a server. The control center station is used for managing the satellite and each ground station.

On the basis, the ground station can be divided into static communication equipment, communication-in-motion equipment and the like according to different use environments.

It should be noted that a stationary device is understood as a stationary ground station, which refers to a communication connection established between satellite stations at a fixed location via a satellite access network. The communication-in-motion equipment can be understood as a mobile ground station, which means that the ground station is arranged on a mobile carrier, and a satellite is tracked in real time and is in communication connection with a satellite station in the process of moving along with the mobile carrier. The satellite communication equipment generally comprises a satellite automatic tracking sub-equipment and a satellite communication sub-equipment, wherein the satellite automatic tracking sub-equipment is responsible for tracking a satellite, and the satellite communication sub-equipment is responsible for communicating with a server through a satellite internet.

In the prior art, when software in the mobile communication equipment needs to be upgraded, for example, a satellite automatic tracking sub-device needs to upgrade a related algorithm of satellite automatic tracking, a local upgrading mode is usually adopted, that is, the software is connected to a circuit board through a special computer, then a special download cable is used for downloading and upgrading the software of a micro control unit in the mobile communication equipment welded on the circuit board, and after the upgrading is completed, the micro control unit is installed back to the mobile communication equipment again. The method has the characteristics of reliability, stability and no network influence, and is a preferred mode for local upgrading.

However, when the mobile communication equipment is delivered to a client and is put into operation, it becomes very difficult to perform an upgrade, and each upgrade needs to be performed by a manufacturer firstly coordinating the upgrade time and place with the client, and then sending a professional to go to the place where the client is located with tools such as a professional computer, which is very inefficient and high in cost.

Therefore, the embodiment of the application provides a method for upgrading software of a communication-in-motion device, wherein the communication-in-motion device receives an upgrading software package sent by a server through a satellite, and an upgrading software file corresponding to the upgrading software package is used for upgrading first software; under the condition that the upgrading software package is successfully received, the upgrading software file corresponding to the upgrading software package is written into a preset address space in the memory, and the stored software file corresponding to the first software is not deleted.

The embodiment of the application provides a method for upgrading software of communication-in-motion equipment, which is applied to a satellite communication link applicable to the communication-in-motion equipment. Fig. 2 shows a satellite communication link suitable for the communication-in-motion device, and in conjunction with fig. 2, the satellite communication link includes a satellite, a server disposed at the control center station, and the communication-in-motion device, and the server and the communication-in-motion device are in communication connection through the satellite.

The communication-in-motion device comprises a memory and a processor, wherein the memory stores a computer program, and the processor realizes the software upgrading method of the communication-in-motion device when executing the computer program.

The storage may be an internal storage unit of the mobile communication device in some embodiments, for example, a hard disk or a memory of the mobile communication device. The memory may also be an external storage device of the mobile communication device in other embodiments, such as a plug-in hard disk provided in the mobile communication device, a Smart Media Card (SMC), a Secure Digital (SD) Card, a Flash memory Card (Flash Card), and the like. The memory may also include both internal and external storage units of the mobile station device. The memory is used for storing applications, data, and other programs, such as program codes of computer programs. The memory may also be used to temporarily store data that has been output or is to be output.

The Processor may be a Central Processing Unit (CPU), and the Processor may be other general purpose Processor, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), an off-the-shelf Programmable Gate Array (FPGA) or other Programmable logic device, discrete Gate or transistor logic, discrete hardware components, etc. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.

It is to be understood that the illustrated structures of the embodiments of the present application do not constitute specific limitations on the communication-in-motion device, and in other embodiments, the communication-in-motion device may include more or less components than those shown, or combine some components, or split some components, or arrange different components. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

The server also comprises a memory and a processor, wherein the memory stores a computer program, and the processor realizes the method for upgrading the software of the communication-in-motion device when executing the computer program.

The memory and the processor in the server may have the same structure as the memory and the processor in the mobile communication device, respectively, and are not described herein again.

The following describes a method for upgrading software of a mobile communication device provided by the present application with reference to a specific example.

As shown in fig. 3, the present application provides a method for upgrading software of a mobile communication device, which can be applied to a satellite communication link to which the mobile communication device shown in fig. 2 is applied. Fig. 3 shows an interaction diagram of a method for upgrading software of a mobile communication device according to an embodiment of the present application. As shown in fig. 3, the method 100 includes S110 to S150, which will be described in detail below.

And S110, the server sends the upgrading software package to the communication-in-motion equipment through the satellite.

The upgrading software package is generated by corresponding upgrading software files, and the upgrading software files are used for upgrading the first software.

The first software refers to any software in the mobile communication device, and may be, for example, software for performing calculation of an automatic satellite tracking algorithm in the mobile communication device. And the upgrading software file for upgrading the first software is written by corresponding program codes, and the first software of the communication-in-motion device can be changed or some content can be newly added by running the upgrading software file.

It can be understood that since the communication-in-motion device is a constituent part of the satellite communication link, the communication-in-motion device has access to the internet during the working process, and provides a basic condition for upgrading.

Based on this, all communication processes performed by the server and the communication-in-motion device in the embodiment of the present application are performed based on that the server first performs communication with the satellite, and then the satellite performs communication with the communication-in-motion device. For example, the server sends the upgrade software package to the communication-in-motion device through the satellite, which means that the server sends the upgrade software package to the satellite first and then the satellite sends the upgrade software package to the communication-in-motion device.

And S120, the communication-in-motion equipment receives the upgrading software package.

S130, under the condition that the upgrade software package is successfully received, the mobile communication equipment writes the upgrade software file corresponding to the upgrade software package into a preset address space in a memory, and does not delete the stored software file corresponding to the first software.

It is understood that successful reception of the upgrade software package means that the mobile communication device communicates via the satellite and completely receives the data of the upgrade software package sent by the server.

After the mobile communication equipment successfully receives the upgrading software package, the upgrading software file corresponding to the upgrading software package can be obtained through unpacking, and the upgrading software file is written into the address space preset in the memory.

It should be noted that, if the first software only corresponds to one software file, the software file is already stored in the memory, and thus the stored software file is not deleted; if the first software corresponds to a plurality of software files, the software files are already stored in the memory, so that the software file with the highest version in the stored software files is not deleted, and the software files with other lower versions can be deleted or continuously stored in the memory.

The memory may be FLASH. Because the communication-in-motion equipment needs to ensure real-time performance and does not use an operating system, when the memory is FLASH, the upgrading software file is written into a preset address space in the FLASH by directly starting the FLASH, and because the stored software file is not deleted, when the subsequent upgrading has problems, the software file corresponding to the stored first software can be found in the memory. Here, the stored software files may be used to upgrade the first software or, alternatively, may be used to install the first software.

And S140, the server sends an operation instruction to the communication-in-motion equipment through the satellite. The running instruction is used for instructing the communication-in-motion equipment to run the upgrading software file at the preset time so as to upgrade the first software.

The server sends an operation instruction to the satellite, and the satellite sends the operation instruction to the communication-in-motion equipment.

Here, if the memory is a FLASH and a plurality of software files corresponding to the first software are stored in the FLASH, in order to correctly instruct the running of the upgrade software file, the running instruction may further carry version information matched with the upgrade software file, so that the mobile communication device may call the upgrade software file corresponding to the version information from the FLASH according to the version information, and thus, the upgrade software file may be correctly run at a preset time.

And S150, the communication-in-motion equipment runs the upgrading software file at the preset time to upgrade the first software.

According to the software upgrading method of the communication-in-motion equipment provided by the embodiment of the application, the communication-in-motion equipment receives an upgrading software package sent by a server through a satellite, and an upgrading software file corresponding to the upgrading software package is used for upgrading first software; under the condition that the upgrading software package is successfully received, the upgrading software file corresponding to the upgrading software package is written into a preset address space in the memory, and the stored software file corresponding to the first software is not deleted.

In addition, it can be understood that when the software of the static and medium communication device needs to be upgraded, the software upgrading method can also be executed, which has the same beneficial effects and is not described herein again.

Optionally, as a possible implementation manner, on the basis of the method step shown in fig. 3, after the step S120, the method further includes: and under the condition that the first software fails to be upgraded, restarting the communication-in-progress equipment, and operating the stored software file corresponding to the first software.

It should be noted that the failure to upgrade the first software includes various situations such as interruption of upgrading the first software, failure of receiving the upgrade software package, and failure of running the upgrade software file.

The upgrade first software interruption refers to an unexpected stop occurring during any one of the upgrades of the first software, for example, a sudden power off of the server during the transmission of the upgrade software package, or a sudden power off of the communication-in-motion device during the reception of the upgrade software package by the communication-in-motion device. The failure of receiving the upgrade software package refers to, for example, that the server has sent the upgrade software package, but the mobile communication device has not received the upgrade software package, or only receives data of a part of the upgrade software package. The failure of running the upgrade software file refers to that although the mobile communication device successfully receives the upgrade software package, the upgrade software package is abnormal and cannot run.

On the basis, under the condition that the first software is not upgraded, the program in the communication-in-motion equipment automatically modifies the starting option parameters and restarts the communication-in-motion equipment, and after the starting of the communication-in-motion equipment, the software file stored with the first software is called and operated, so that the communication-in-motion equipment can continue to work, and the stability and the reliability of the communication-in-motion equipment are ensured.

If a software file corresponding to the first software is stored, running the software file when the communication-in-progress device is restarted; and if the plurality of software files corresponding to the first software are stored, operating the software file with the highest version in the stored plurality of software files when the communication-in-process equipment is restarted.

Illustratively, the mobile communication device successfully receives the upgrade software file P2 and receives an operation instruction, which instructs the mobile communication device to start to operate the upgrade software file P2 at a preset time, for example, 1 month, 1 day, and 6 o' clock, to upgrade the first software. However, when the mobile communication device runs the upgrade software file P2 at 6 o ' clock 1 month and 1 day, after a preset time period, for example, 10 minutes later, the mobile communication device cannot normally access the satellite communication link for communication, and then automatically reboots, and a second attempt to run the upgrade software file P2 is started at 10 o ' clock 6 o ' clock 1 month and 1 day. If the communication-in-motion device cannot be normally accessed to the satellite communication link for communication after the preset time length for the second time, namely 6 o 'clock and 20 o' clock in 1 month and 1 day, the problem of upgrading the software file is possibly solved, and the upgrading of the first software fails due to unsuccessful operation.

In this case, in order to ensure that the mobile communication device communicates normally, the mobile communication device is automatically restarted, and the software file corresponding to the stored first software is run, for example, the software file corresponding to the stored first software includes a software file P0 and a software file P1, where the version of the software file P1 is the highest compared with the version of the software file P0, and thus, in order to ensure that the mobile communication device can operate normally after 1 month, 1, 6, 20 minutes, the software file P1 corresponding to the first software is recalled and run, so as to maintain the satellite communication link to continue communication, thereby ensuring the stability and reliability of the upgrade when an abnormality occurs during the upgrade process.

Optionally, as a possible implementation manner, taking fig. 4 as an example, on the basis of the method steps shown in fig. 3, before S110, the method 100 may further include S108 and S109.

For the description of S110 to S150 shown in fig. 4, reference may be made to the above description of these several steps by taking fig. 3 as an example, and for brevity, the description is not repeated here.

And S108, the server divides the upgrading software file into a plurality of upgrading sub-software files.

It can be understood that, because the bandwidth resource of satellite communication is limited and data communication of users cannot be affected during the software upgrading process, before the server sends the upgrade software file to the satellite communication-in-motion device through the satellite, the server may segment the upgrade software file into a plurality of upgrade sub-software files, and thus, when the upgrade software file is sent to the satellite communication-in-motion device later, one or a plurality of upgrade sub-software files with smaller data volume may be sent each time, thereby adapting to the smaller bandwidth resource.

Optionally, after the step S108, the server may further verify the correctness of the split multiple upgrade sub-software files.

Illustratively, the verification is performed by using an exclusive or Check, or a Cyclic Redundancy Check (CRC), so as to ensure that the original correctness of the plurality of upgrade sub-software files can be maintained after the upgrade software file is divided.

S109, the server encrypts the plurality of upgrading sub-software files respectively to generate a plurality of encrypted upgrading sub-software packages.

The upgrading sub-software file is encrypted, so that the safety of data can be guaranteed. The encryption mode is set as required, and the present application is not particularly limited thereto.

Illustratively, the encryption mode may be byte inversion, or exclusive or operation of the byte and a preset fixed value.

On this basis, in the above S110, the server sends the upgrade software package to the mobile communication device through the satellite, including:

and the server sends a plurality of encrypted upgrading sub-software packages to the communication-in-motion equipment through the satellite.

It should be noted that, the server may send one or several encrypted upgrade sub-software packages to the mobile communication device at different times in a time period by using a time-sharing transmission mode through a satellite.

Because the server sends a plurality of encrypted upgrading sub-software packages to the communication-in-motion equipment through the satellite, and the satellite communication usually has a large delay, in the transmission process, preset logics such as overtime waiting, abnormal retransmission of the upgrading sub-software packages and the like exist to ensure normal transmission.

Optionally, as a possible implementation manner, taking fig. 5 as an example, on the basis of the method steps shown in fig. 4, the above S120 may further include S121 to S123.

The descriptions of S108 to S110 and S130 to S150 shown in fig. 4 may refer to the above description of these steps with fig. 4 as an example, and for brevity, are not repeated here.

And S121, the communication-in-motion equipment receives a plurality of encrypted upgrading sub-software packages through a satellite.

And S122, the communication-in-motion equipment decrypts the encrypted upgrading sub-software package to obtain a plurality of corresponding upgrading sub-software files. It is understood that the decryption method corresponds to the server-side encryption method.

And S123, splicing the plurality of upgrading sub-software files by the communication-in-motion equipment to obtain upgrading software files.

It can be understood that after the mobile communication device receives all the upgrade sub-file files, the plurality of upgrade sub-software files are spliced, so that the complete upgrade software file which is desired to be sent by the server side can be restored.

In order to ensure the correctness of the spliced upgrade software file, the server can correspondingly mark the upgrade software file into a plurality of upgrade sub-software files and respectively encrypt and package the upgrade sub-software files, and simultaneously transmit the mark when transmitting the encrypted upgrade sub-software package, so that the communication-in-the-middle equipment can sequence according to the mark corresponding to each upgrade sub-software package after receiving the encrypted upgrade sub-software packages, thereby splicing the decrypted upgrade sub-software files in sequence and correctly restoring the upgrade software file.

Optionally, as a possible implementation manner, taking fig. 6 as an example, on the basis of the method steps shown in fig. 5, before S108, the method 100 may further include S105 to S107.

For the description of S108 to S150 shown in fig. 6, reference may be made to the above description of these several steps by taking fig. 5 as an example, and for brevity, the description is not repeated here.

And S105, the server sends a state inquiry command to the communication-in-motion equipment through the satellite.

The state query instruction is used for querying whether the communication-in-motion equipment is in the scalable state. The upgradeable state may be a locked state or other state that indicates that the mobile station device can upgrade the first software.

For example, the server sends a state query instruction to the mobile communication device through the satellite, and as long as data is transmitted back to the server from the mobile communication device through the satellite, the mobile communication device is normal in operation, and at this time, the mobile communication device can be considered to be in a locked state and can be upgraded.

And S106, the communication-in-motion equipment sends the indication information responding to the state inquiry instruction to the server through the satellite. The indication information is used for indicating that the communication-in-motion device is in a scalable state.

And S107, the server receives the indication information and determines that the communication-in-motion equipment is in an upgradable state, and the server executes the steps S108 to S150 to upgrade the first software.

Here, if the server cannot determine that the mobile communication device is in the upgradable state, for example, the server does not receive the instruction information, the server does not execute the above S108 to S150, and does not perform the upgrade.

Alternatively, in the method shown in fig. 3, S105 to S107 may also be included.
