The present invention relates to a method and a system for providing a FOTA service. In particular, the present invention relates to an M2M module and a method and system for providing FOTA services for various devices connected to the M2M module.

BACKGROUND With the development of wireless communication technology, terminals including various services and functions for user convenience have been provided. As such various services and functions are added, the software mounted on the mobile terminal also increases the probability of generating many bugs, and there is an increasing demand for the addition of new functions after the release of the mobile terminal.

Accordingly, FOTA (Firmware Over The Air), a solution for automatically upgrading the firmware of a mobile terminal wirelessly, has been developed. Here, firmware generally refers to a micro program that controls hardware stored in a ROM, and is the same as software in terms of a program, but is separated from general application software in that it is closely related to hardware. It has the characteristics of

Referring to the standards related to FOTA established by OMA (Open Mobile Alliance), an international mobile standardization organization, FOTA service execution of a mobile terminal includes receiving a notification message from a device management (DM) server, A discovery process, which is a process of performing communication between the server and the mobile communication terminal, includes a process of downloading an update package.

Therefore, the FOTA service has the advantage that a user can wirelessly download and update the modified program of the mobile terminal without visiting the A / S center.

On the other hand, M2M (Machine to Machine) is a remote management and control solution that supports communication between machines by connecting the M2M module and the device by using a wired / wireless communication method to a series of user traffic data in a general wired / wireless network. In addition, various program updates such as NV (Non Volatile) setting values, firmware, drivers, and application applications are required for performance improvement and error correction of the M2M module and the devices connected thereto. However, even if each program is updated, there is a problem that an error occurs or an improved service cannot be used if any one is not updated by managing the update program for each version.

In addition, since the heterogeneous devices connected to the M2M module are optional and thus cannot provide FOTA services, there is a problem in that the M2M market is limited due to the inconvenience of the customers whose programs are not properly compatible.

Accordingly, an object of the present invention is to provide a method and system for providing FOTA services for an M2M module and various devices connected thereto.

Extract version information about. In addition, the latest update data corresponding to the identification information of the current M2M module and the latest update data corresponding to the type and model information of the device connected to the M2M module 100 is collected and compared only the data that needs to be updated to the latest version. Detect.

Then, the detected update data is compressed to generate update packaging, stored in a database, and the stored location (address) is transmitted to the M2M module through the SMSC 300. In this case, although omitted in the drawing, a separate download server may be further configured to store the update packaging.

The SMSC 300 notifies the DM server 200 of the update package request received from the M2M module 100, generates a processed update package response message from the DM server 200, and delivers the updated package response message to the M2M module 100.

The operator terminal 400 may be an operator computer that inquires / changes NV data, and accesses the DM server 200 according to an event such as expansion of a device connectable to the M2M module 100 to register the NV data as the latest version. .

The manufacturer server 500 is an operator that develops the M2M module 100 and devices connected thereto, and verifies update data such as drivers, firmware, and application programs developed for performance improvement, service expansion, and interworking of each device. Register at).

The verification server 600 tests the update data and registers the verified data in the latest version to the DM server 200 according to the simulation.

On the other hand, since the M2M module 100 according to an embodiment of the present invention is a device connected to and interlocked with various devices, an update for accommodating various devices must be essentially performed. Therefore, a method of providing a FOTA service for the M2M module 100 according to an embodiment of the present invention will be described with reference to FIG. 3.

An update package request message including the information is generated and transmitted to the DM server through the SMSC 300 (S403 and S404).

The DM server 200 analyzes the received update package request message and extracts manufacturer / model information of the navigation and version information of the applications and software currently used (S405). Then, the update data corresponding to the extracted information is queried to detect the most recently updated version of the application and the map data (S406). Then, the DM server 200 compresses the detected latest version of the application and map data to generate an update package response message (S407), and transmits the M2M module 100 through the SMSC 300 (S408, S409).

The M2M module 100 accesses the DM server 200 through the update package location information included in the received update package response message and downloads the corresponding update package (S410). On the other hand, although omitted in the drawing, if there is no update package location information in the received update package response message or there is no response within a preset time, it may be determined that there is no update package and may be ignored.

The M2M module 100 analyzes the downloaded update package, decompresses the update package, and executes verification of the first and last images to check whether the download of the update package is normally performed (S411).
