Hereinafter, the operation principle of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intentions or customs of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification.

The present invention relates to a method and system for performing a platform upgrade first when a platform version of a mobile communication terminal is low when a mobile communication terminal attempts to download content through a wired or wireless Internet network, And to implement a platform upgrade system based on device management (hereinafter referred to as "DM") and a content download system linked to it.

In this case, when the content is downloaded from the mobile communication terminal, the minimum version of the downloadable content is checked and if it is higher than the platform version of the downloaded content, the download information of the content to be downloaded first is stored, After the platform upgrade, the download procedure for the content that was previously downloaded is automatically performed based on the downloaded download information.

Here, DM is an extension of the standard called Client Provisioning. It is an extension of the former that deals with only the phone-related settings, so that it can deal with the settings that are handled by general application programs (various settings in the case of the browser, etc.). In addition, existing Client Provisioning is a main function that enables the mobile communication terminal to communicate with the mobile communication terminal by transmitting the proper information to the mobile communication terminal, while the DM allows the mobile communication company to read the current mobile communication terminal setting.

In addition, DM is based on the International Mobile Synchronization Communication Standard (SyncML). SyncML is a language used to synchronize with PC when address book is managed by PDA. The DM can be said to synchronize the current terminal configuration with the database in the mobile carrier. Therefore, the latest settings can be mutually updated regardless of which one is updated, so that the mobile communication company can know the setting details changed by the user, and can directly change settings in the mobile communication company. In addition, firmware upgrade (FOTA: Firmware Over the Air) and download application can be executed using DM, so firmware upgrade or application update can be used on the same platform.

As an example of utilization of the mobile communication terminal using such a DM, a user of the DM-based mobile communication terminal can remotely perform the service without having to visit the A / S center directly for bug correction or S / W upgrade of the mobile communication terminal . In addition, FOTA, Remote Diagnostics, and new feature upgrades are available wirelessly. This can enable A / S cost reduction and rapid service implementation even for mobile carriers.

1 is a T-PAK platform structure used in a mobile communication system. The T-PAK platform is a mobile communication terminal, in which application software of a mobile communication terminal manufacturer and additional services and solutions of a mobile communication company are connected to a WIPI Internet Platform for Interoperability) platform platform to provide a development environment for mobile terminals.

In addition, T-PAK is a service-oriented platform that supports the WIPI 2.0 standard and is the latest trend of mobile communication terminal platform. Especially, it can upgrade the platform wirelessly through OTA (over the air) technology. It is possible to download a new service of a mobile communication company which is not available in the future.

The T-PAK platform is modularized according to detailed functions for efficient platform upgrade. Each module or subsystem is in the form of a dynamic system library (DSL) 100.

The DM server of the mobile carrier manages the platform version and the upgrade DSL that constitutes the platform version.

Example) TPAK 1.10.00: AA.dsl (ver 1.0 ), BB.dsl (ver1.0), CC.dsl (Ver1.0), ....

TPAK 1.11.00: AA.dsl (ver 1 .1 ), BB.dsl (Ver1.0), CC.dsl (Ver1.0), ....

Also, when the platform upgrade of the terminal is required, the DM server compares the DSLs constituting the platform version of the current mobile communication terminal with the DSLs constituting the target platform version to be upgraded, and transmits the DSL of the higher version to the mobile communication terminal do.

2 is a diagram illustrating a DSL loading procedure in a mobile communication terminal according to a preferred embodiment of the present invention.

2, the mobile communication terminal stores the DSL received from the DM server of the mobile communication company in the EFS (Embedded File System) area 206 in the FLASH ROM 200, and the EFS area 206 The DSL is loaded into the RAM 202 prior to the corresponding DSL in the code area 204. [

For example, as shown in FIG. 2, the BB received from the DM server of the mobile communication company. dsl V1.1 is stored in the EFS area 206 in the FLASH ROM 200 and is stored in the code area 204 in the FLASH ROM 200 as a DSL that performs the same function as the same subsystem. dsl (V1.0) is located in the code area 204 when the platform is loaded. BB located in the EFS area 206 than dsl (V1.0). dsl (V1.1) is loaded into the RAM 202 first. This enables the platform to be upgraded using DSL.

That is, since the DSL data located in the EFS area 206 rather than the DSL data located in the code area 204 are upgraded DSL data, the DSL data located in the code area 204 and the EFS area 206 at the time of platform operation overlap , And loads the DSL located in the EFS area 206 into the RAM 202 first.

3 is a diagram illustrating a platform upgrade and a content downloading procedure according to a preferred embodiment of the present invention.

3, the mobile communication company includes a download system 304 and a DM server 306. The mobile communication terminal 308 includes a download manager and a DM agent. Here, the download system 304 includes a content registration server for registering content by the content provider, the DM server 306 registers the upgrade DSL from the platform developer, and in response to the platform upgrade request of the mobile communication terminal 308 The mobile communication terminal 308 upgrades the required DSL.

The download manager of the mobile communication terminal 308 checks the minimum operable platform version when downloading the content through the wired / wireless Internet and compares the platform version with the platform version of the current mobile communication terminal to determine whether to upgrade the platform. In addition, when the DM agent of the mobile communication terminal 308 performs the platform upgrade request to the DM server in cooperation with the download manager, the DM agent stores the download information to be downloaded first, .

In step 310, the content provider (CP) 300 registers the content in the content registration server 304 in the download server 304 of the mobile communication company, As well as the minimum platform version required to run. The platform developer 302 periodically registers the newly developed platform upgrade DSL in the DM server 306 in step 312.

Thereafter, in step 314, the mobile communication terminal 308 downloads the content to the mobile communication company's download system 304 so that the download system 304 transfers the content to the mobile communication terminal 308. [

At this time, the platform version information of the content is included in a download descripter (DD) file indicating the property of the content, and is transmitted to the mobile communication terminal 308 before the content is downloaded.

Figure 112007059889583-pat00001

Table 1 shows download descriptor files of specific contents, which indicates that the minimum supported T-PAK platform version is "TPAK 2.0.1 Rev 11.5.7 ".

In step 316, the download manager of the mobile communication terminal 308 checks the minimum operable platform version of the content in the download descriptor file transmitted at the time of downloading the content, If the platform version of the mobile communication terminal 308 is lower than the minimum operable platform version by comparing the actual platform version of the terminal 308, the download manager ends the content download procedure that was being performed first in step 320, The platform upgrade request message is forwarded to the DM agent in step 308. [ The DM agent delivers the platform upgrade request message received from the download manager to the DM server 306. [

At this time, the download manager of the mobile communication terminal 308 delivers the download information of the contents to be downloaded to the DM agent, and the DM agent stores the corresponding information in a file form. Here, the download information of the contents may be location information (URL) in which contents to be downloaded are stored, and download command information for downloading.

If the DM server 306 receives the platform upgrade request from the DM agent of the mobile communication terminal 308, the DM server 306 configures the DSLs constituting the platform version of the current mobile communication terminal 308 and the target platform version to upgrade in step 322 And transmits the DSLs to be upgraded to the mobile communication terminal 308 through comparison between the DSLs.

The mobile communication terminal 308 stores the corresponding DSL received from the DM server 306 in the EFS area in step 324 and reflects the upgraded contents by restarting the platform. For example, "OEMC_knlRegAgent (" RUNONCE ", FALSE," A000000044 ", 1," DSLUPGRADE_RESTART ");" The platform is restarted by the command, which sets the DM agent to run after restarting the platform.

In step 326, the DM agent transfers the download information of the content that was stored in a separate file, that is, the content that was to be downloaded before the platform upgrade, to the download system 304 so that the content download is retried . That is, after confirming the position where the content can be downloaded through the location information among the download information of the content, the download is re-executed based on the download command information.

By constructing a content download system that is used in conjunction with a platform upgrade and a platform in this manner, new content can be downloaded from a mobile communication terminal having a lower version of the platform.

As described above, according to the present invention, when a mobile communication terminal attempts to download content through a wired / wireless Internet network, if the platform version of the mobile communication terminal is low, the mobile communication terminal first performs platform upgrade, The downloading procedure for the user can be performed automatically.
