Referring to FIG. 2, the mobile terminal 300 according to the embodiment of the present invention includes an A mode unit 310, a B mode unit 320 and a common mode unit 330, and a core framework 340. . The core framework 340 manages the entirety of the A mode unit 310, the B mode unit 320, and the common mode unit 330, which are upper application components, and the upper components of the lower core framework 340. Under control.

The A mode unit 310 includes a packet call processing unit 331 related to packet call processing with the A mode mobile communication network 100, a circuit call processing unit 312 related to circuit call processing, and a protocol processing unit related to protocol processing for mobile communication. 313, and a device portion 314 associated with the device of the mobile terminal. The B mode unit 320 includes a packet call processing unit 321, a circuit call processing unit 322, a protocol processing unit 323, and a device unit 324 for communication with the B mode mobile communication network 200.

The common mode unit 330 may include a packet call processing unit 331, a circuit call processing unit 332, which may be commonly configured among software structures for communicating with the A mode mobile communication network 100 and the B mode mobile communication network 200. The protocol processor 333 and the device unit 334 are included.

The core framework 340 communicates with the higher mode application component A mode 310, the B mode 320 and the common mode 330 through Interface Definition Language (IDL), and controls and manages the higher application component. It plays a role. The core framework 340 according to an embodiment of the present invention includes a common component manager 341, a resource 342, a profile manager 343, a parser 344, a file manager 345, and a domain manager 346. ), A device manager 347, a Booter 348, and an Installer 349.

The common component manager 341 according to an embodiment of the present invention manages the common mode unit 330, and the resource 342 is a process, memory, communication port, and quality of service (QoS) of the mobile terminal 300. ), And so on. The profile manager 343 manages the type, attributes, and installation / uninstallation, deployment, and execution method of the upper application component as profile information in the form of XML (eXtensible Markup Language), and the parser 344 is managed by the profile manager 343. Parse a managed XML profile.

The file manager 345 plays a file system management role of the core framework 340, the domain manager 346 manages domains in A mode and B mode, and the device manager 347 of the mobile terminal 300. Manage your device.

From 348 allows the mobile terminal 300 to initially perform a boot function, and the installer 349 installs / uninstalls the upper application component.

The common component manager 341, the file manager 345, the domain manager 346, the device manager 347, and the installer 349 are included in a default system that should basically operate for the operation of the mobile terminal 300.

The multi-mode processing procedure of the multi-mode mobile terminal 300 according to the embodiment of the present invention as described above is as follows.

3 is a diagram illustrating a multi-mode processing method of a multi-mode mobile terminal according to an embodiment of the present invention.

Referring to FIG. 3, when the mobile terminal 300 initially turns on the power, 348 performs a booting procedure (S301), and the profile manager 343 searches for a default system profile related to the initial booting. The parser 344 parses the default system profile retrieved by the profile manager 340, and based on the information obtained as a result of the parsing, the common component manager 341 and the file manager. 345, domain manager 346, device manager 347, and installer 349 are deployed and executed. (S304)

When the booting initial process of the mobile terminal 300 according to the step S301 to step 304 is completed, the mobile terminal 300 until receiving a user's request or a request of an external program-an automatic plug and play program. Will be on standby.

When receiving a request for the placement and execution of a particular mode application component (S305), the installer operates for the execution of the application component of the mode, first of which the required mode is checked for commonness of the application component of the requested mode. Ask the parser 344 to parse the application profile.

At this time, if the parser 344 parses all the profiles of the profile manager 343, power consumption is severe, so only the meta information of the profile necessary for the public availability check is parsed (S306). The meta information may include a universally unique identification (UUID) of a higher application component.

In addition, when the common component manager 341 is inquired of the common possibility of each component according to the parsing result of step S306 (S307), the common component manager 341 compares meta information of various modes to determine whether there is a common possibility among them. do.

As a result of the determination in step S307, if the common component does not exist, the entire application profile of the corresponding mode is parsed (S308), and the device unit 314 or 324 of the higher application components is used by the device manager 347 using the information obtained as a result of the parsing. The installer 349 batch-executes the packet call processing section 311 or 321, the circuit call processing section 312 or 322, and the protocol processing section 313 or 323 (S311). That is, when there is no shared component, the entire profile is parsed according to each mode so that the device manager 347 and the installer 349 can deploy and execute it.

As a result of the determination in step S307, if there is a shared component, the parser 344 parses the remaining profile except for the profile related to the shared component (S308), and uses the remaining application while using the shared application component using the parsed information. The layout and execution of the component is performed (S309).

As described above, according to the exemplary embodiment of the present invention, when all the components of the A mode unit and the B mode unit are shared as shown in FIG. 2, only the deployment and execution of one mode is performed in the operation of the multi-mode mobile terminal 300. In this case, both A and B modes can be used, so only minimal power can be consumed. In addition, even if there are components that are not shared in addition to the components in which A mode and B mode are shared, power consumption can be reduced by parsing, deploying, and executing the shared components only once.

Therefore, according to the embodiment of the present invention, even when applying a new mode, it is possible to facilitate the addition of the mode regardless of the size of the terminal by adding only the portions for the components that are not shared in software.

As mentioned above, although the Example of this invention was described, this invention is not limited only to the Example mentioned above, A various other change and a deformation | transformation are possible.

As described above, according to the present invention, by componentizing all the software of the multi-mode mobile terminal and by configuring the components commonly required for each mode as a common component, to reduce the power consumption in multi-mode processing and add hardware when adding a new mode Changes to the software can be made to facilitate the addition of modes.
