The present invention relates to a method of controlling an application using a function of a WAP (Wireless Application Protocol) browser on a wireless Internet platform for Interoperability (WIPI). will be. More specifically, an application running on the WIPI, which is a basic operating system for using the wireless Internet of a mobile communication terminal, is provided through a browser functional application program interface (BF API). The present invention relates to a method of using a browser component dependent on a swap browser in another application other than the swap browser by using a browser component componentized according to the function of a browser application.

The mobile communication system has been developed through the first generation analog AMPS (Advanced Mobile Phone System), the second generation cellular (Cellular) and personal communication service (PCS), and recently, the third generation high-speed data. International Mobile Telecommunication-2000 (IMT-2000) has been developed. 1X systems and EV-DO systems are called 2.5 generations because they use the same frequency bands (800 MHz, 1.8 GHz) as the second generation of cellular / PCS services and provide some of the IMT-2000 functionality called the third generation.

In the first and second generation schemes, voice communication is mostly performed using a mobile communication terminal, and data communication has been extremely limited. However, with the advent of 2.5 generation and 3 generation systems due to the steady development of mobile communication technology, the mobile terminal has recently become a core tool for performing data communication.

Recently, with the development of internet and multimedia data technology, a content provider (CP) that provides various contents such as multimedia communication, network game, and video game has emerged, and various services provided by the content provider are provided to mobile communication terminals. The number of mobile subscribers to use has increased.

Therefore, using a wireless machine based on a virtual machine as a wireless internet environment, a mobile device can run embedded applications that are embedded when a mobile terminal is released, or content provided by a content provider on an information server. Generated as an application running on a wireless Internet platform and transmitted to a mobile communication terminal carried by a mobile subscriber through a mobile communication network, and the downloaded mobile communication terminal executes the application using the provided wireless Internet platform. .

However, as the wireless Internet service using the wireless Internet platform has been in the spotlight, mobile communication providers providing mobile communication services have different wireless Internet in order to promote the excellence of mobile communication services provided by each and to differentiate mobile communication services. The platform was developed to provide wireless Internet service. Wireless SK Telecom's GVM, SKVM, MAP and LG Telecom's KVM are examples of wireless Internet platforms developed by mobile operators. As a result, the wireless Internet platform has been changed depending on the mobile operator, causing the application to be incompatible.

In addition, the content providers that provide content to mobile operators also need to create and provide applications to the respective wireless carriers to provide them to each mobile operator. The cost has increased.

To solve this inefficiency, WIPI was born with the intention of unifying the wireless Internet platform that is developed and used differently according to the mobile carriers, and the contents provider developing the application suitable for the unified wireless Internet platform.

WIPI refers to a mobile standard platform specification that is installed in a mobile communication terminal and provides an environment for executing an application. A platform that meets WIPI (hereinafter referred to as 'WIPI') ensures the compatibility of applications for mobile operators developing applications for mobile terminals, and makes it easy to port the wireless Internet platform to mobile terminal developers. In addition, it provides various and rich contents services to mobile subscribers.

1 is a view for explaining the conceptual structure of the WIPI.

Mobile terminal hardware and basic software 110 is composed of a hardware device constituting a mobile communication terminal and software for performing the basic functions of the mobile communication terminal. Here, the hardware is a microprocessor that controls all devices and overall functions of the mobile communication terminal, nonvolatile memory utilized as a storage device, random access memory (RAM) that temporarily stores data and is randomly accessible. ), A user interface unit, a digital signal processor, a baseband converter, and an RF signal processor. In addition, the basic software includes software for performing basic functions of mobile communication performed by the mobile communication terminal and drivers of various devices.

A mobile terminal adaptation layer (HAL) 120 is a layer for supporting hardware independence in the mobile terminal manufacturer's porting of the wireless Internet platform to the mobile terminal. Through this, an abstraction of hardware of the mobile communication terminal is achieved, and a wireless internet platform is formed independently of the hardware. That is, the upper layers operate independently of the basic software 110 of the mobile communication terminal through the HAL 120.

The WIPI real-time engine 130 is an engine implemented using only a standardized application program interface (API) of the HAL 120. In addition, the essential API 140 provides C and Java APIs as a collection of essential APIs supported by the wireless Internet platform. Essential APIs include Mobile Standard Foundation (MSF), Mobile Standard Profile (MSP), Connected Limited Device Configuration (CLDC), and Mobile Information Device Profile (MIDP). Here, MSF is a basic API for portable devices and supports input / output functions, networks, security, internationalization, and the like. MSP is a profile for MSF-based portable devices. CLDC is a configuration for virtual machine-based portable devices. CLDC consists of a virtual machine and a core API. MIDP is an overview for CLDC based portable devices.

The dynamic component 150 is an API and components added or updated through a WIPI application manager (WAM: WAM) 160. The WAM 160 performs application management functions such as downloading, installing, and deleting an application, and adds or updates APIs and components (DLL: Dynamic Linking Library, hereinafter referred to as 'DLL'). Perform administrative functions.

Application 170 is a collection of various applications that run on a wireless Internet platform, such as e-mail, location-based services, games, characters / bells, video streaming, group chats, and the like.

Such a WIPI can add and update APIs through a wireless Internet network, and the addition and updating are performed through a DLL. The DLL is a means of adding new APIs or updating existing APIs on the wireless Internet platform.
