The present invention relates to a method of performing a FOTA service of a mobile communication terminal.

FOTA (Firmware Over The Air) is a solution that automatically upgrades the firmware of a mobile terminal wirelessly.

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

Conventionally, when the DM server sets a user interaction or information option and transmits a notification message to the mobile communication terminal, the user of the mobile communication terminal can confirm a discovery step, which is a communication process between the DM server and the mobile communication terminal, through the user interface. there was.

In addition, even if the mobile communication terminal sets an option for the communication with the DM server in the background and transmits a response message to the DM server, the process of downloading the update package is not performed in the background mode.

Therefore, the mobile communication terminal should show the download progress of the update package to the user through the user interface, and the user had to use a multitask key to perform another task during the download process of the update package.

Meanwhile, when the location of the mobile communication terminal belongs to a roaming area while performing the FOTA service, a method of processing a notification message received from a DM server is as follows.

In other words, there was a first method of processing a notification message regardless of a roaming region and a second method of not processing a notification message in a roaming region.

The first method handles the notification message regardless of roaming area, but in this case, the service provider should consider the billing problem, and if the home area is the 3rd generation network and the roaming area is the 2nd generation network, smooth communication service is not provided. there was.

In the second method, the roaming area does not process the notification message. Therefore, when the mobile communication terminal returns to the home area, the user cannot use the FOTA service unless the DM server sends a notification message again.

In addition, after downloading the update package from the DM server, the user typically checks whether to update or postpone the update. When the user requests the update postponement, the mobile communication terminal subsequently ignores the notification message received from the DM server, because the update of the downloaded package has not been completed yet.

In other words, even when the DM server urgently sent a notification message to correct the error of the terminal, if the notification message is received after the request for postponing the update of the user, the DM server is ignored so that both the user and the service provider have to suffer damage.

Accordingly, an object of the present invention is to provide a method for performing a FOTA service of a mobile communication terminal to perform a FOTA service in a background mode in a mobile communication terminal.

Another object of the present invention is to provide a method for performing a FOTA service of a mobile communication terminal capable of efficiently processing a notification message received from a DM server in a roaming area.

Technical problems to be achieved by the present invention are not limited to the above-mentioned technical problems, and other technical problems not mentioned above may be clearly understood by those skilled in the art from the following description. There will be.

According to an embodiment of the present invention, a method for performing a FOTA service in a mobile communication terminal includes: setting a background option; Receiving a notification message from a server in a background mode; Performing communication between the server and the mobile communication terminal in a background mode; And downloading the update package from the server to the mobile communication terminal in a background mode.

After the download of the update package is completed, if another application is not executed by checking whether another application is running, an update popup screen for checking whether the downloaded package is updated is displayed.

After the download of the update package is completed, if another application is running, the update pop-up screen is displayed when the running application terminates.

If the mobile communication terminal is located in a roaming area or communication with the server is lost, the download of the update package is stopped.

If the mobile communication terminal moves to the home area or the communication with the server is connected while the download of the update package is stopped, the download of the update package is resumed.

According to another embodiment of the present invention, a method for performing a FOTA service of a mobile communication terminal may include receiving a notification message from a server; Determining which area of the roaming area and the home area the mobile communication terminal is located in, and storing the received notification message in a memory when the mobile communication terminal belongs to the roaming area; Generating a response message in response to the notification message and transmitting the response message to the server when belonging to the home area; And downloading and storing the update package from the server by communicating with the server.

The steps are performed in background mode.

When the mobile communication terminal returns to the home area while the notification message is stored in the memory, a response message to the notification message stored in the memory is generated and transmitted to the server.

When the download of the update package is completed, an update popup screen for selecting whether to perform the update of the downloaded package immediately or after a predetermined time elapses is displayed.

When a notification message is received from the server in a state in which an update is requested to be performed after a predetermined time elapses, the mobile communication terminal checks in which area of the roaming area and the home area, and receives it when it belongs to the roaming area. The notification message is stored in a memory, and when the message belongs to the home area, a response message to the notification message is generated and transmitted to the server.

2 is a flowchart provided to explain a method of performing a FOTA service of a mobile communication terminal according to the first embodiment of the present invention. In the present embodiment, it is assumed that the mobile communication terminal 100 has a background option set by the user.

Referring to FIG. 2, first, the mobile communication terminal 100 receives a notification message from the DM server 10 (S205). The mobile communication terminal 100 transmits a response message to the notification message to the DM server 10.

Thereafter, a discovery step in which communication is performed in the background mode between the DM server 10 and the mobile communication terminal 100 is performed (S210). In the discovery phase, the DM server 10 and the mobile communication terminal 100 discuss whether there is a need to update the software package of the mobile communication terminal, and if there is a need to update the software package, the mobile communication terminal 100 Request the DM server 10 to provide an update package.

In the present embodiment, the discovery step proceeds to a background mode, which means that the discovery step is executed without a user interface being provided.

In addition, when there is a need to update the software package, the mobile communication terminal 100 downloads the update package from the DM server 10. At this time, the download process of the update package also proceeds to the background mode (S215).

In other words, since the update package is not downloaded to the user interface, the user of the mobile terminal may use various services (eg: browser, text, phone, game, streaming, etc.) without knowing whether the update package is being downloaded. Thus, there is no interference from the FOTA in using the mobile communication terminal.

As described above, while the update package is downloaded in the background mode, the mobile communication terminal 100 is located in the roaming area, or the signal received from the DM server 10 is turned off and the communication with the DM server 10 is lost. If (S220: Y), the mobile communication terminal 100 stops downloading the update package (S225).

In general, roaming means that when a user of a mobile terminal leaves the service area of a mobile service provider to which he / she subscribes, the user of the mobile terminal can receive services of another mobile communication service provider concluded through a contract. Refers to a service that does not cause inconvenience in using a communication service.

That is, in this embodiment, the roaming area refers to an area where a user of the mobile communication terminal receives a communication service from another mobile communication service provider out of the service area of the mobile communication service provider to which the mobile communication terminal subscribes.

In the present embodiment, when the mobile communication terminal 100 is located in the roaming area, the reason for stopping the download of the update package is that when the network operated by another mobile communication service provider is a second generation network, the update package cannot be downloaded normally. If a case may occur, it is to prevent this in advance.

In addition, in the present embodiment, when the signal is turned off, it means that the mobile communication terminal is moved underground to receive a signal from the DM server 10.

While the download of the update package is interrupted, the mobile communication terminal 100 is located outside the roaming area in the home area, or a signal received from the DM server 10 is turned on to communicate with the DM server 10. When resumed (S230), the mobile communication terminal 100 resumes the download of the update package from the DM server 10 (S235).

When the download of the update package is completed from the DM server 10 to the mobile communication terminal 100 (S240: Y), the controller 130 of the mobile communication terminal 100 checks whether another application is being executed by the user (S245). ).

As a result of the check, when another application is not currently being executed (S250: N), the controller 130 controls the display unit 160 to display an update popup screen (S260).

On the contrary, when another application is currently running (S250: Y), the controller 130 controls the display popup screen to be displayed on the display unit 160 when the running application is terminated and returns to the standby screen (S255). .

As such, when the specific application is not running by the user or when the specific application is terminated and returned to the standby screen, the update popup screen is displayed, so that the user can use the currently running service without any interruption.

3 is a flowchart provided to explain a method of performing a FOTA service of a mobile communication terminal according to a second embodiment of the present invention.

Referring to FIG. 3, the mobile communication terminal 100 receives a notification message from the DM server 10 (S305).

Upon receiving the notification message, the mobile communication terminal 100 checks whether its current location belongs to a roaming area through a base station (not shown) (S310).

As a result of the check, if not belonging to the roaming area (S310: N), the mobile communication terminal 100 processes the notification message received from the DM server 10 and transmits a response message to the notification message to the DM server 10. (S315).

On the contrary, when belonging to the roaming area (S310: Y), the controller 130 of the mobile communication terminal 100 stores the notification message received from the DM server 10 in the memory unit 140 and processes the notification message. To reserve (S320).

When the mobile communication terminal 100 belongs to a roaming area and the notification message received from the DM server 10 is stored in the memory unit 140, the mobile communication terminal 100 is located in a home area outside the roaming area. In operation S325: Y, the mobile communication terminal 100 processes the notification message stored in the memory 140 and transmits a response message to the DM server 10 to the DM server 10 (S330).

Subsequently, a discovery step in which communication is performed between the DM server 10 and the mobile communication terminal 100 is in progress, and when there is a need for software update, the mobile communication terminal 100 downloads an update package from the DM server 10. The memory unit 140 stores the memory 140 in the memory unit 140 (S335).

When the download is completed, the controller 130 of the mobile communication terminal controls the display unit 160 to display an update popup screen (S340).

4 is a diagram illustrating an update popup screen according to an embodiment of the present invention. Referring to FIG. 4, the update pop-up screen 400 includes a [progress] menu for executing the update immediately with a guide message “Do you want to update the downloaded package?” And for the update to be executed after a predetermined time. Contains the Smoke menu.

When the user selects the [Go] menu through the input unit 150 (S345: N), the control unit 130 of the mobile communication terminal 100 performs an update using the update package downloaded from the DM server 10. (S350).

On the contrary, when the user selects the [Smoke] menu through the input unit 150 (S345: Y), the update of the software package is delayed after a predetermined time. At this time, the update delay time can be set by the user.

In step S345, if the [delay] menu is selected, and the notification message is not received from the DM server 10 until the update postponement while the update is postponed (S355: N), the update proceeds at the preset postpone time ( S360).

In addition, in step S345, when the [delay] menu is selected and a notification message is received from the DM server 10 while the update is postponed (S355: Y), the control unit 130 repeats steps S310 to 340. Control to be performed.

That is, the controller 130 checks the location to which the mobile communication terminal 100 currently belongs, and stores a notification message newly received from the DM server 10 in the memory unit 140 when the current location is a roaming area. Suspend processing of one notification message.

When the newly received notification message is stored in the memory unit 140 and the mobile communication terminal 100 moves to the home area, the mobile communication terminal 100 processes the notification message stored in the memory unit 140 to notify it. The response message to the message is transmitted to the DM server 10.

In addition, when the current location is the home area, the controller 130 of the mobile communication terminal 100 processes the received notification message and transmits a response message to the notification message to the DM server 10.

In this way, when the processing of the newly received notification message is completed, the postponed update is canceled.

The mobile communication terminal 100 determines the necessity of a software update by communicating with the DM server 10, and downloads a new update package from the DM server 10 and stores it in the memory unit 140 when an update is required.

At this time, the update package previously stored in the memory unit 140 is deleted, and the update by the newly downloaded update package is performed.

In the above-described second embodiment of the present invention, the notification message receiving step, the communication step with the DM server, the update package download step, and the like may be performed in the background mode as in the first embodiment.
