The present invention relates to a key input signal processing method in a mobile communication terminal. More particularly, the key mapping information is generated when a key input signal is generated in a state in which key mapping information set in an interactive application for a standby mode is registered in a wireless Internet platform. The present invention relates to a key input signal processing method for an interactive application for a standby mode in a mobile communication terminal for querying a corresponding key input signal to be processed by an interactive application for a standby mode or to be processed by a system application.

Recently, with the development of mobile communication terminal technology, users can enjoy content such as video, music, games, etc. through the mobile communication terminal.

For example, when a user does not make a call (aka standby mode) by changing the contents of the contents when the user does not make a call by designating the contents preloaded on the mobile communication terminal or downloaded through the Internet as a wallpaper. (Hereinafter, contents and programs whose contents are changed by the user's key operation in the standby mode are referred to as "Interactive Application for Sleep Mode").

A technology related to such an interactive application for standby mode is disclosed in Korean Patent Laid-Open Publication No. 2003-87525 (name of the invention: "a method of playing interactive content for standby mode in a mobile communication terminal and a mobile communication terminal using the same").

When the user designates a content provided from a terminal manufacturer or a content provider as a background mode for the standby mode, the multimedia player is driven to execute an interactive application in the standby mode, and an event corresponding to a key input signal from the user is generated. A method of displaying on an interactive application for a standby mode is disclosed.

On the other hand, while the interactive application for the standby mode is running, it is necessary for the user to easily use the mobile communication terminal specific functions (phone number search / input function, call / receive function, short message transmission / reception function, etc.).

In the above-described prior art, when the mode switching key input signal is generated while the mode switching key input signal is being executed and the standby mode interactive application is being executed, the user stops the execution of the interactive application for the standby mode and switches to the mobile terminal use mode. Has applied a method for allowing a specific function of the mobile communication terminal to be used.

However, in order to provide a mobile communication terminal specific function to the user while the interactive application for the standby mode is being executed in the prior art as described above, it is necessary to generate a mode switching key input signal and switch to the mobile communication use mode. After saving the data of the interactive application for standby mode, it must be terminated.

That is, although the display related system resources, the sound related system resources, etc. allocated to the interactive application for the standby mode need to be released, the mobile terminal specific function can be performed.

Accordingly, there is a problem in that the time required for storing, de-allocating, and terminating the data of the interactive application for the standby mode is delayed, thereby providing a delay in providing the user with the specific function of the mobile terminal.

On the other hand, such an interactive application for the standby mode is downloaded or executed on the Wi-Fi through the middleware-type Korean wireless Internet standard platform called Wifi (WiFi Platform). For example, a system application that performs a mobile terminal specific function is executed on an operating system (eg, "REX OS", etc.) pre-loaded by the terminal manufacturer.

Therefore, the mobile terminal designation function (telephone number search / input function, whether the key input signal for processing the key input signal from the user, that is, the content content of the interactive application for standby mode) is terminated without terminating the interactive application for standby mode. Call input / receive function, short message transmission / reception function, etc.), and input the key input signal from the user to the interactive application for standby mode through the Wi-Fi platform so that the corresponding event is generated. Or, there is an urgent need for a technology for transmitting a key input signal from a user to a system application through an operating system so that a corresponding mobile terminal specific function is performed.

The present invention has been proposed to solve the above problems and to meet the above demands. When the key input signal is generated in the state in which the key mapping information set in the interactive application for standby mode is registered in the wireless Internet platform, To provide a key input signal processing method for an interactive application for a standby mode in a mobile communication terminal to query the mapping information so that the corresponding key input signal is processed by an interactive application for a standby mode or a system application. There is this.

According to an aspect of the present invention, there is provided a wireless communication platform, comprising: a first step of registering key mapping information set in a standby mode interactive application to a wireless Internet platform when an interactive application for standby mode is executed; A second step of determining the specific key input signal through key mapping information registered in the wireless Internet platform when a specific key input signal is generated; A third step of controlling an event corresponding to the specific key input signal by the interactive application for the standby mode when the specific key input signal is registered in the key mapping information as a result of the key input signal determination; And a fourth step of controlling a mobile communication terminal specific function corresponding to the specific key input signal by a system application if the specific key input signal is not registered in the key mapping information as a result of the key input signal determination. .

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, detailed descriptions of well-known functions or configurations will be omitted if it is determined that the detailed description of the present invention may unnecessarily obscure the subject matter of the present invention. Terms to be described later are terms defined in consideration of functions in the present invention, and may be changed according to intentions or customs of users or operators. Therefore, the definition should be made based on the contents throughout the specification.

It includes a control unit 17 for delivering to the application. In addition, the mobile communication terminal includes basic components (not shown) for mobile communication.

FIG. 2 is a diagram illustrating a hierarchical structure of an interactive application and a system application for a standby mode mounted in the mobile communication terminal of FIG. 1.

As shown in Fig. 2, the content layer, which is the top layer on the mobile communication terminal to which the present invention is applied, includes a telephone number list (e.g., a list of telephone numbers for each group) 20, a message list (e.g., incoming / outgoing short message). 21) and contents (e.g., video, game, flash, etc.) 22, and a system application (e.g., phone number search program, message management program, etc.) 23 in the application (solution) layer. And an interactive application 24 for standby mode, and a wireless internet platform layer, that is, a Wi-Fi platform 25, is mounted below the standby mode interactive application 24, and the system application 23 and the Wi-Fi are installed. An operating system (eg, REX OS, etc.) 26 is mounted below the platform 25, and a hardware layer, that is, a control unit (eg, MSM, etc.) 17 and a key input unit 14, are installed below the operating system 26. ), A microphone 15, a display unit 13 and speaker 16 are mounted.

In the present invention, while the interactive application for the standby mode is running, the user operates the key input unit 14 to enjoy the contents of the interactive application for the standby mode or the user operates the key input unit 14 to perform the mobile communication terminal specific function. When a key input signal is generated to be used, the key mapping information registered in the WiPie platform 25 is inquired, and if the key input signal is used for the interactive application for the standby mode, the key input signal is transmitted to the interactive application for the standby mode to generate a corresponding event. If a key input signal for a system application is passed to the system application to perform the corresponding function.

Meanwhile, although the WiPi platform 25 is illustrated as an example in FIG. 2, those skilled in the art will readily understand that any module performing a wireless Internet platform function, such as "WITOP" of "Eske Telecom Co., Ltd." may be applied to the present invention.

3 is a flowchart illustrating a key input signal processing method for an interactive application for a standby mode in a mobile communication terminal according to the present invention.

First, while the interactive application 24 for the standby mode is executed (300), the key mapping information is registered in the WiPie platform 25 (301). For example, in order to enjoy the game "Raising fish" in the standby mode, the user outputs the game list through the menu of the mobile terminal, selects the game "Raising fish" and sets the game as a wallpaper. The interactive application 24 for execution.

At this time, the interactive application 24 for standby mode calls the " OEMC_knlSetKeyMap () " function to register itself, in particular, key mapping information set in the content 22 on the Wi-Fi platform 25.

In general, when the application is executed, all key input signals generated by the key input unit 14 are transmitted to the application through the operating system 26 or / and the WiPi platform 25, in the present invention, the WiPi platform 25 The key mapping information of the interactive application 24 for standby mode is registered in the standby mode, and the corresponding key input signal is checked through the Wi-Fi platform 25 for the key input signal generated afterwards. The associated key input signal is transmitted to the interactive application 24 for the standby mode through the Wipy platform 25.

The key mapping information is set according to the attributes of the standby mode interactive application 24. The key mapping information is set differently from other interactive modes for the standby mode according to the attributes of the interactive mode application 24 for standby mode.

In addition, the key mapping information is valid until the interactive application 24 for the standby mode is in a foreground state, that is, until the program is terminated after being registered in the WiPie platform 25, and after completion of the program, the WiPie platform 25 is completed. It is preferable that the key mapping information registered at is released.

The key mapping information described above is described in detail as follows.

The key mapping information indicates whether the key input signal generated from the key input unit 14 should be processed by the interactive application 24 for the standby mode, that is, the content change of the content 22 (e.g. tropical fish up / down / left / right Information about whether it is to be used for a mobile communication or the like, or to be processed by the system application 23, that is, whether to be used for performing a mobile communication terminal specific function (for example, calling a speed dial number, etc.).

Table 1 below shows key mapping information.

Key Flag SEDN F Num_1 F Num_2 F Fn_1 T Fn_2 T End T Cancel T * F # F .. ..

Such key mapping information is preferably set in the interactive application 24 for the standby mode or in the content 22.

That is, the screen forward key, the screen backward key, and the tropical fish up, down, left and right navigation keys related to playing a video are set differently, and according to the attributes of the interactive application 24 or the content 22 for the standby mode. Preferably, the key mapping information is set differently.

In Table 1, the key whose flag is set to "F" (for example, "SEND", "Num_1", etc.) is not used for the interactive application 24 for the standby mode, but for the system application 23. A key (eg, "Fn_2", "End", etc.) whose flag is set to "T" is not used for the system application 23, but used for the interactive application 24 for standby mode.

Meanwhile, an application program interface (API) related to the aforementioned "OEMC_knlSetKeyMap ()" function will be described in detail as follows.

The prototype (prototype) of the "OEMC_knlSetKeyMap ()" function is represented by "M_Int32 OEMC_knlSetKeyMap (M_Int32 MapRange, M_Int32 size, M_Int32 * userKeyMap)".

"MapRange" among the parameters of the "OEMC_knlSetKeyMap ()" function is a key map setting option. When the key mapping information is set to other options than "MC_KEYMAP_USER", all previously set key mapping information values are released. size "indicates the size of the user specified key map buffer, and" userKeyMap "indicates the user specified key map buffer.

Table 2 below shows the key map setting options.

Key mapping setup options Key values contained in the key map Remarks MC_KEYMAP_FREE All keys set in the key map are released size, userKeyMap ignored MC_KEYMAP_USER Custom key map, added to existing key values    MC_KEYMAP_CONTROL All keys other than MC_KEY_SOFT1, MC_KEY_SOFT2, MC_KEY_LEFT, MC_KEY_RIGHT, MC_KEY_UP, MC_KEY_DOWN, MC_KEY_SEND, MC_KEY_END, MC_KEY_CLEAR, MC_KEY_SELECT are included in the key map.    size, userKeyMap ignored    MC_KEYMAP_CONTROL_NO_SELECT All keys other than MC_KEY_SOFT1, MC_KEY_SOFT2, MC_KEY_LEFT, MC_KEY_RIGHT, MC_KEY_UP, MC_KEY_DOWN, MC_KEY_SEND, MC_KEY_END, MC_KEY_CLEAR, are included in the key map    size, userKeyMap ignored    MC_KEYMAP_CONTROL_NO_END Key map contains all keys other than MC_KEY_SOFT1, MC_KEY_SOFT2, MC_KEY_LEFT, MC_KEY_RIGHT, MC_KEY_UP, MC_KEY_DOWN, MC_KEY_SEND, MC_KEY_CLEAR, MC_KEY_SELECT    size, userKeyMap ignored   MC_KEYMAP_CONTROL_NO_SELECT_END All keys other than MC_KEY_SOFT1, MC_KEY_SOFT2, MC_KEY_LEFT, MC_KEY_RIGHT, MC_KEY_UP, MC_KEY_DOWN, MC_KEY_SEND, MC_KEY_CLEAR are included in the key map.   size, userKeyMap ignored

Thereafter, the key input unit 14 continuously checks whether a specific key input signal is generated while the interactive application 24 for standby mode is executed (302).

When a specific key input signal is generated from the key input signal generation test result 302 and the key input unit 14, the key input signal is determined by referring to the key mapping information registered in the Wi-Fi platform 25 (303).

At this time, the "303" process consists of a query / response between the operating system 26 and the Wi-Fi platform 25. That is, the controller 17 continuously monitors whether a key input signal is generated by the system, in particular, the key input unit 14 based on the operating system 26, and when a key input signal is generated, the function "OEMH_pltCheckOEMKeyMap ()". Call to return the response result ("True" or "false") to the result of querying the key input signal to the WiPie platform (25).

The following is a part of code related to "OEMH_pltCheckOEMKeyMap ()" function.

if (OEMH_pltGetPlatformState () == MH_PLTSTATE_FOREG) {

M_Int32 ret;

switch (in_event) {

case MH_KEY_PRESSEVENT:

If (OEMH_pltCheckOEMKeyMap (keyCode) == 0) {

// Wifi platform if the key input signal cannot be processed by the WIPI platform 25

// (25) (interactive application for standby mode 24) transitions to background

// process the corresponding key input signal in the system application 23

MH_pltEvent (MH_BACKG_EVENT, ...);

ret = OEMH_pltProcessEvent ();

break;

}

default:

MH_pltEvent (in_event, param);

ret = OEMH_pltProcessEvent ();

}

if (ret == M_E_PLTEXIT) {

// exit the Wifi platform (25)

} else {

// WIPI platform 25 normally handles events corresponding to key input signals

}

}

When a specific key input signal is generated from the key input signal generation test result 302 and the key input unit 14, the key input signal is determined by referring to the key mapping information registered in the Wi-Fi platform 25 (303).

As a result of determining the key input signal 303, if the specific key input signal is a key input signal registered in the key mapping information, the specific key input signal is transmitted to the interactive application 24 for the standby mode (304). At this time, it is determined through the "True" signal returned from the WiPie platform 25 that the specific key input signal was a key input signal registered in the key mapping information.

Accordingly, the standby application interactive application 24 generates an event corresponding to the key input signal (305).

On the other hand, if the key input signal determination result 303, the specific key input signal is not a key input signal registered in the key mapping information, the specific key input signal is transmitted to the system application 23 (306). At this time, the "False" signal returned from the WiPie platform 25 determines that the specific key input signal is a key input signal not registered in the key mapping information.

Then, the system application 23 is executed (307), and performs a mobile communication terminal specific function corresponding to the corresponding key input signal (e.g., phonebook search function, call / receive function, short message creation function, etc.) 308). At this time, the interactive application 24 for standby mode is switched to a background task (e.g., the interactive application 24 for standby mode transitions to an idle state awaiting generation of a key input signal related to content content change / operation, and corresponding content contents. Will not appear on this screen).

Then, when the mobile communication terminal specific function is terminated, that is, the system application 23 is terminated (309), after activating the interactive application for the standby mode that has been switched to the background operation (310), the process proceeds to the "302" process. The process of continuously checking whether a specific key input signal is generated in the key input unit 14 is performed.

While the content of the present invention has been described by way of examples, the embodiments of the present invention are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention. Those skilled in the art to which the present invention pertains may modify or alter the present invention in various forms within the principles and scope described in the claims herein.

 As described above, the present invention registers the key mapping information of the interactive application for the standby mode in the wireless Internet platform and delivers it to the interactive application for the standby mode or to the system application according to the result of inquiring the key input signal. It is possible to distinguish the key input signal from the user, and accordingly, there is an effect that a specific content change / manipulation or mobile communication terminal specific function corresponding to the key input signal can be performed by an application having a different execution environment.

In addition, the present invention as described above, even if a key input signal for a mobile communication terminal specific function is generated in the standby mode, the background processing of the interactive application for the standby mode, the effect that the applications having different execution environment can be executed simultaneously There is.
