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.
The system upgrading method provided by the application can be applied to the application environment shown in fig. 1. Wherein the first terminal 110 communicates with the second terminal 120 through a network. The second terminal 120 receives the system upgrade instruction sent by the first terminal 110, and the second terminal 120 analyzes system upgrade information carried in the system upgrade instruction to obtain a first upgrade parameter; the second terminal 120 acquires the second system information and the second security information; determining second check-up information according to the second system information and the second safety information; the first upgrade parameter is verified through the second verification information, and when the verification is passed, the second terminal 120 downloads the upgrade file according to the first upgrade parameter; and executing system upgrade according to the upgrade file. The first terminal 110 and the second terminal 120 may be, but are not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices.
In an embodiment, as shown in fig. 2, a system upgrade method is provided, which is described by taking the application of the method to the second terminal in fig. 1 as an example, and includes the following steps:
step 202, receiving a system upgrade instruction, and analyzing system upgrade information carried in the system upgrade instruction to obtain a first upgrade parameter.
Specifically, the second terminal receives a system upgrade instruction sent by the first terminal, extracts carried system upgrade information from the received system upgrade instruction, and analyzes the extracted system upgrade information to obtain a first upgrade parameter. The system upgrade information is information indicating the second terminal to execute system upgrade, and the system upgrade information may be encrypted information, so that the second terminal performs decryption processing according to the received encrypted system upgrade information to obtain the first upgrade parameter.
It should be noted that the first terminal and the second terminal are different terminals, and the first terminal and the second terminal can perform remote communication through a network to implement data interaction.
In one embodiment, the system upgrade instruction comprises a short message instruction; after receiving the system upgrade instruction, the method further comprises: extracting a first terminal identification from the short message instruction; matching the first terminal identification with a terminal identification prestored in a second terminal for receiving a system upgrading instruction; and when the matching is successful, judging the system upgrading instruction to be a legal instruction, and executing the step of analyzing the system upgrading information carried in the system upgrading instruction to obtain a first upgrading parameter.
The first terminal identifier is used for uniquely identifying one terminal, and specifically may be information such as a mobile phone number of the terminal. One or more terminal identifications are pre-stored in the second terminal, wherein the terminal identification can be information such as a mobile phone number. Therefore, when the second terminal receives the short message instruction sent by the first terminal, the mobile phone number for sending the short message instruction is obtained, the obtained mobile phone number is compared with the phone number prestored in the second terminal, and when the comparison is successful, the first terminal for sending the short message instruction is a legal terminal, and the short message instruction is a legal instruction, so that the step of analyzing the system upgrading information carried in the system upgrading instruction to obtain the first upgrading parameter can be executed. Otherwise, when the comparison fails, the first terminal sending the short message instruction is an illegal terminal, and the communication event needs to be prevented to ensure the information security. It should be noted that the information pre-stored in the second terminal may be stored locally or stored in the cloud server, which is not limited herein.
Step 204, second system information and second security information are obtained.
The second system information and the second security information may be information corresponding to the second terminal. Specifically, the second system information is used to uniquely identify a second terminal, and the second system information may specifically be a system identifier of the second terminal, for example, the second system information is a system serial number of the second terminal. The second safety information is safety information used for identifying the second terminal, the second safety information is uniquely corresponding to one second terminal, and the second safety information is safety data agreed by the second terminal and the first terminal in advance, so that the safety of the information interaction can be determined according to the second safety information agreed in advance when the first terminal and the second terminal are communicated. For example, the second security information may specifically be a security code or a security identifier or a security character, and the like, which is not limited herein.
Note that, the first terminal stores security information corresponding to different terminals in advance, and uses the security information as the first security information. In an embodiment, when the first terminal has a right to communicate with the second terminal, the first terminal should store second security information corresponding to the second terminal, so that when the first terminal communicates with the second terminal, identity verification can be performed according to the security information agreed in advance, and when the security information carried by the first terminal and the second terminal is determined to be consistent, the information interaction is legal and safe, so that subsequent data interaction between the first terminal and the second terminal can be continuously performed. The second terminal stores second safety information corresponding to the second terminal. In specific implementation, when the first terminal and the second terminal perform communication interaction, the first terminal carries first safety information, and the safety of the information interaction is determined by checking whether the first safety information is consistent with the second safety information. When the first safety information carried in the first terminal is inconsistent with the second safety information stored in the second terminal, the situation that potential safety hazards exist in the communication at this time is indicated, so that a safety alarm should be sent out, and safety verification is carried out on the information interaction at this time again.
Step 206, determining second check-up information according to the second system information and the second security information.
The second verification information is used for verifying the legality of the first upgrading parameter. Specifically, the splicing information may be obtained by splicing the second system information and the second security information, and the splicing information is used as the second verification information. That is to say, in order to ensure the safety of information interaction, the second check information includes double safety information, the first is the check of the system information, the second is the check of the safety information, when any one of the safety information has a potential safety hazard, it can be determined that the potential safety hazard exists in the current information interaction, and then the height of the safety check is improved. In order to further improve the interactive security of the information, the second check information or the first check information may be encrypted, and the security of information transmission in the network may be improved by the encryption, so as to prevent the information from being tampered.
And 208, verifying the first upgrading parameters through the second verification information, and downloading the upgrading files according to the first upgrading parameters when the verification is passed.
In one embodiment, the second check information is a sequence value, the first upgrade parameter is also a sequence value, and the check of the first upgrade parameter according to the second check information is realized through comparison of the sequence values. And when the verification is passed, the second terminal executes the first upgrade downloading upgrade file sent by the first terminal. The first upgrade file is a file required for system upgrade.
Specifically, the first upgrade file may be a differential package, and the system upgrade is performed according to the downloaded differential package. And specifically, the differential upgrade can also adopt a promotion scheme, the promotion scheme provides an executable program required by the differential package production, and the promotion strategy is to modify the differential relationship between the partition.xml configuration source package and the target package file. Xml is more efficiently produced in order to reduce errors caused by artificial modification of partition.
And step 210, performing system upgrade according to the upgrade file.
Specifically, the second terminal locally executes system upgrade according to the downloaded upgrade file.
As shown in fig. 3, fig. 3 is a schematic diagram of interaction between an upper computer and an MDM in a first terminal and a second terminal provided in an embodiment. And the terminal can also perform data interaction with the FTP server. In fig. 3, an upper computer (MCU) is used as a first terminal to send an instruction to a second terminal MDM9607 to be upgraded, the instruction may be an AT + neoftpta instruction, or a specific short message is sent, after the MDM9607 receives the characteristic instruction, the MDM9607 is connected to a server to start downloading an upgrade package, where the server may specifically be an FTP server, and the downloaded upgrade package is returned to the upper computer, so that the upper computer executes system upgrade according to the received upgrade package.
According to the system upgrading method, when the second terminal receives the system upgrading instruction sent by the first terminal, the system upgrading instruction is analyzed to obtain a first upgrading parameter; second system information and second safety information corresponding to a second system to be upgraded are obtained; determining second check-up information corresponding to a second system to be upgraded according to the second system information and the second safety information; the first upgrading parameters are verified through the second verification information, and when the verification is passed, the upgrading files are downloaded according to the first upgrading parameters; and performing system upgrade on the second system to be upgraded according to the upgrade file. After a system upgrading instruction is received, information carried in the upgrading instruction is analyzed and verified, when the verification is passed, the upgrading instruction is proved to be a legal instruction, an upgrading package is downloaded according to the upgrading instruction, remote system upgrading of the system to be upgraded is executed according to the upgrading package, and remote upgrading of the system to be upgraded is achieved while safety is guaranteed.
And in some scenes, downloading the differential packet which is deployed in advance from the FTP server to a module in the terminal so as to upgrade. Specifically, the module establishes PPP connection and sends an AT instruction through a serial port tool to trigger FTP remote upgrading. However, the upgrading only supports the serial port tool to trigger upgrading through an AT instruction issuing mode, part of users are already in commercial use, upgrading conditions are limited, equipment cannot be upgraded through the method, and the module only supports the serial port tool to operate a single module to upgrade. The problem that the upgrading condition is limited can be solved by using a short message triggering upgrading mode, and the plurality of modules are upgraded simultaneously by sending short messages in batches, so that labor and time are saved, and the working efficiency is improved. By changing the triggering mode of remote upgrading, the mode of sending short messages is used for triggering remote upgrading, and the real remote upgrading is realized.
As shown in fig. 4, fig. 4 is a schematic diagram of a remote upgrade of a terminal module provided in an embodiment. In fig. 4, a server of the FTP version communicates with a terminal device via a network. And the server and the mobile terminal can perform data interaction in the form of AT commands and short messages. The server referred to in this application may be an FTP server, or may be a server of another version, and is not limited herein.

According to the method and the device, online upgrading is designed, software upgrading can be triggered in a mode of sending short messages or AT instructions, the operation is simple, the upgrading efficiency, safety, reliability and flexibility are guaranteed, and the manpower and material resource cost is reduced through a remote upgrading scheme. In some scenes, the triggering of upgrading by using an AT instruction mode is possibly limited, and remote upgrading is triggered by using a short message mode, so that the labor and material cost is reduced, the upgrading mode is more flexible, the upgrading result is obvious, the remote upgrading in the real sense is realized, and short messages can be sent in batches for large-scale upgrading.

The first system information is information pre-stored in the first terminal, specifically information corresponding to other terminals stored in the first terminal, and when the first terminal and the second terminal have an interaction right, the system information of the second terminal may be pre-stored in the first terminal. That is, the first system information stored in the first terminal may have data identical to the second system information. Specifically, the first system information is used to uniquely identify a terminal, and the first system information may specifically be a system identifier of the terminal, such as a system serial number of the terminal. The first security information is also information which is stored in advance and uniquely corresponds to one terminal, the security information corresponding to one or more terminals respectively is stored in the first terminal in advance, the stored security information is used as the first security information, when the first terminal and the second terminal have communication rights, information which is consistent with second security information corresponding to the second terminal can exist in the first security information, and when the first terminal and the second terminal communicate, the security of the communication can be checked by checking whether the first security information is consistent with the second security information. Specifically, the first security information may specifically be a security code or a security identifier or a security character, and the like, which is not limited herein.
In one embodiment, the target information is an AT command, and the AT command includes configuration information such as an address, a port number, an upgrade package name, a user name, and a password for configuring the connection FTP, so as to download the corresponding upgrade file through the target information. In one embodiment, the specific form of the AT command may include the following form: AT + neoftfota? And inquiring the downloading progress.
It should be noted that, most of the module industries perform data interaction through TCP/UDP or other methods, remote upgrade may also be triggered by sending a TCP/UDP message, and the triggering methods are flexible and varied.

A specific application scenario is taken as an example to explain the scheme. By configuring a receiving element such as an SIM card in the module to be upgraded in the second terminal in advance, the short message can be received through the SIM. When the module to be upgraded is needed to be upgraded, a short message is sent to the module to be upgraded remotely, for example, on another mobile phone terminal, after the module to be upgraded receives the short message, the module to be upgraded analyzes the received short message information, and module upgrading is executed according to an analysis result. It should be noted that the corresponding application scenario may be some modules that need to be upgraded, and the upgrading operation cannot be performed locally, for example, some modules that are not suitable for manual upgrading and are not suitable for contact.
