FIG. 3 is a schematic diagram of a local upgrade process of an M2M terminal according to the present invention. detailed description

The basic idea of the present invention is: When the M2M platform knows that the upgrade server has a new upgrade package, the upgrade information is sent to the M2M communication module; the M2M communication module verifies the upgrade information, and when the upgrade information is correct, the upgrade package is downloaded from the upgrade server. After that, the M2M communication module performs its own upgrade operation, and reports the upgrade success message to the M2M platform after the upgrade is completed.

The upgrade operation performed by the M2M communication module is as follows: After the M2M communication module sets an upgrade flag, restarts, performs an upgrade operation according to the set upgrade flag, and then clears the upgrade flag and sets an upgrade completion flag, and the M2M communication mode The group restarts again; the upgrade completion flag is used to determine that the upgrade is successful, and then the upgrade completion flag is cleared, and the upgrade success message is reported to the M2M platform. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

The upgrade server is configured to notify the M2M platform when the new upgrade package is saved, that is, during the maintenance process of the upgrade package file, notify the M2M platform when the upgrade package of the upgrade package is found to have a newly added upgrade package, and execute Upgrade package download operation with M2M communication module;

The creation is: adding information such as a uniform resource locator (URL) of the upgrade server, a version of the upgrade package, and a size of the upgrade package to the upgrade information.

In the present invention, since the upgrade server is only used for maintenance and storage operations of the upgrade package, and the M2M platform is the management center of the M2M terminal, and the upgrade information of the M2M terminal is managed, the M2M communication module executes itself. After the upgrade operation, the upgrade success message is reported to the M2M platform instead of being reported to the upgrade server.

The upgrade operation performed by the M2M communication module is specifically as follows: setting an upgrade flag and restarting, performing an upgrade operation according to the set upgrade flag, then clearing the upgrade flag and setting an upgrade completion flag, and restarting again; determining the successful upgrade by using the upgrade completion flag. Then clear the upgrade complete flag.

Here, the purpose of the clearing upgrade completion flag is to prevent the flag from affecting the next upgrade operation of the M2M terminal, for example: after the next upgrade package download is completed, the M2M communication module restarts and finds an upgrade completion flag, which may cause M2M communication. The module directly ends the upgrade process without performing an upgrade operation on the newly downloaded upgrade package.

The M2M communication module further includes: an upgrade control module, an upgrade execution module, and a service Run the module and flash (Flash);

Specifically, the downloaded upgrade package stored in the Flash covers the area corresponding to the normal running of the M2M terminal in the Flash, and then the upgrade control module is notified.

Here, since Flash has a plurality of different areas for storing the M2M terminal running code, the downloaded upgrade package or the upgrade flag and the upgrade completion flag, the upgrade execution module does not overwrite the upgrade package and the upgrade flag when overwriting the Flash. Or the corresponding storage area of the upgrade completion flag, after the upgrade package is called from the corresponding storage area in the Flash, and overwrites the M2M terminal running code storage area, that is, the upgrade execution module only covers the normal operation of the M2M terminal. Flash area.

The service running module is configured to send the upgrade information sent by the M2M platform to the upgrade control module, forward the upgrade package request information sent by the upgrade control module to the upgrade server, and send the response response of the upgrade server to the upgrade control module; After receiving the notification of the upgrade control module, download the upgrade package from the upgrade server, store it in Flash, and upgrade the upgrade control module to The work message is reported to the M2M platform;

The method for remotely upgrading the M2M communication module of the present invention comprises two parts, namely: a remote download process of the M2M communication module upgrade package and a local upgrade process of the M2M communication module, and the two parts are described in detail below with reference to the accompanying drawings.

The size and other information to inform the M2M communication module that there is a new upgrade package. Here, the upgrade information is sent to the upgrade control module via the service running module in the M2M communication module.

The upgrade information is carried by the operator's M2M specification related protocol, such as: China WMMP protocol.

Step 203: The M2M communication module verifies the upgrade information. If the upgrade information is correct, the execution is performed. Step 204; If the upgrade information is incorrect, step 205 is performed;

Specifically: after the upgrade control module in the M2M communication module receives the upgrade information, check whether the upgrade information is correct, such as: determining whether the URL of the upgrade server is valid, and if the upgrade information is correct, executing step 204; if the upgrade information is incorrect Then, step 205 is performed.

Step 204: The M2M communication module downloads the upgrade package from the upgrade server.

Specifically, when the M2M communication module can be idle, that is, does not affect the normal service operation, the upgrade control module sends the upgrade package request information to the upgrade server via the service running module, and after receiving the response response from the upgrade server, the service operation module is notified. The existing file transfer protocol (FTP) or Hypertext Transfer Protocol (HTTP) downloads the upgrade package from the upgrade server to the local device, that is, downloads to the Flash in the M2M communication module, and executes step 205.

Step 205: The download process of the upgrade package ends.

FIG. 3 is a schematic diagram of a local upgrade process of an M2M terminal according to the present invention. As shown in FIG. 3, the implementation steps of the process are as follows:

Step 301: After the upgrade package is downloaded, the M2M communication module sets the upgrade flag and restarts; specifically: After the upgrade package is downloaded, the upgrade control module in the M2M communication module sets the upgrade flag and stores it in the Flash, and then restarts the M2M. Communication module.

After the upgrade flag is restarted as the M2M communication module, the upgrade control module determines a flag for the M2M communication module to transition from the normal service running state to the upgrade state.

Here, the upgrade process may be performed when the M2M communication module is idle, that is, after the upgrade package is downloaded, the upgrade operation is not required to be performed immediately.

Step 302: Perform an upgrade operation according to the set upgrade flag, and then clear the upgrade flag and set an upgrade completion flag.

Specifically, after the M2M communication module is restarted, the upgrade control module determines that the upgrade status is currently required to be upgraded according to the upgrade flag set in the Flash, and then the upgrade execution module is triggered to perform the upgrade operation, that is, the upgrade execution module stores the downloaded upgrade stored in the Flash. Package covers M2M terminal in Flash The corresponding area in normal operation, and then notify the upgrade control module, the upgrade control module clears the upgrade flag in the Flash, and sets the upgrade completion flag to be stored in the Flash.

Step 303: The M2M communication module is restarted, and the upgrade completion flag is cleared after the successful upgrade. Specifically, the upgrade control module restarts the M2M communication module again. After the M2M communication module is started, the upgrade control module determines the M2M through the upgrade completion flag in the Flash. If the communication module upgrade is successful, the upgrade completion flag in Flash is cleared.

Step 304: The M2M communication module sends a success message to the M2M platform, and the upgrade process ends.

Specifically, the upgrade control module in the M2M communication module reports the upgrade success message to the M2M platform via the service operation module, and then the entire upgrade process ends.
