The present invention relates to an apparatus and method for interfacing with a WIPI platform, and more particularly, to an interface apparatus and method for implementing a WIPI platform, which is a wireless Internet standard, on an operating system for a wireless communication device.

Currently, mobile operators in Korea provide wireless Internet services by adopting different wireless application protocols (WAP, ME). This changed the development environment of content providers through the wireless Internet, which in turn acted as an obstacle to the activation of the wireless Internet, and thus, the standardization of the wireless internet was urgently required. In particular, as mobile carriers introduced the infrastructure (CDMA2000 1x, W-CDMA) to form the full-fledged wireless Internet service market, it was necessary to promote standardization of the wireless internet market. Specifically, the multimedia service is available in the text-based wireless Internet as the packet-based 2.5G and 3G infrastructures, which are capable of providing high-speed packet transmission, are established based on 2G mobile communication. As it is being developed, it is urgently required to respond to this standardization. As a result, the wireless internet for interoperability (WIPI) is a result of the domestic mobile platform standard development plan that is independent and open to terminal and content development to overcome various problems caused by various platforms of mobile carriers.

1 illustrates a conceptual structure of a mobile standard platform defined by the WIPI standard. Referring to FIG. 1, the WIPI platform is composed of four layers of terminal hardware, terminal basic software, mobile standard platform, and application program. The terminal basic software includes a simple terminal operating system, communication basic functions, and various device drivers. The basic software of the terminal varies in function and size depending on the manufacturer. In particular, Microsoft's Windows CE and Symbian's Symbian OS are widely used as terminal operating systems. In order to accommodate such various types of terminal operating systems, the WIPI standard provides a handset application layer (HAL) layer in the terminal basic software to abstract the terminal software when looking at the terminal basic software from the WIPI platform.

HAL is a layer to support hardware independence in platform porting. This creates an abstraction for the terminal and configures the platform independently of the hardware. For example, in the case of a domestic CDMA terminal, porting only the HAL to the Qualcomm OS (REX) becomes a platform for the terminal, while Windows porting only the HAL becomes an emulator for Windows. Therefore, if the terminal manufacturer implements the HAL API only once, there is an advantage in that various platform implementations are quickly ported.

Basic APIs (BASIC APIs) are a collection of basic APIs that consist of C and Java APIs supported by the platform used by application developers. The C and Java APIs provide equivalent APIs in terms of functionality. In the platform specification, the Java language application program is set to run in binary like C language application program, so developers can develop in their preferred language. In general, most applications can be produced in the Java language, and applications related to multimedia codecs or security modules that are very sensitive to speed are expected to be produced in the C language.

On the other hand, in terms of the terminal operating system, Microsoft's Windows CE is basically an operating system developed based on Windows that runs on high-end systems such as personal computers. However, the mobile communication terminal is a low specification system, and the operating speed and memory capacity of the CPU are limited compared to general personal computers. Therefore, Windows CE developed based on high-end system is not an optimized operating system for mobile communication terminals. In contrast, Symbian OS's Symbian OS is an operating system developed based on a low-end system, which accurately reflects the characteristics of the system. In other words, Symbian's Symbian OS is a more effective operating system in the role of smartphone integrated system such as the connection between the smartphone part and PDA part, data service, and messaging. However, in spite of these advantages, no method for accommodating WIPI on Symbian OS, which is an operating system for Symbian mobile communication terminals, has been proposed.

The present invention has been made in an effort to provide an apparatus and method for interfacing between a Symbian OS, which is an operating system for a mobile communication terminal, and a WIPI platform.

Another object of the present invention is to provide a computer-readable recording medium having recorded thereon a program for executing an interfacing method between a Symbian OS, which is an operating system for a mobile communication terminal, and a WIPI platform.

The interfacing method with the WIPI platform according to the present invention for achieving the above another technical problem, the API provided by the operating system of the mobile communication terminal and the API provided by the WIPI platform to interface the operating system and the WIPI platform of the mobile communication terminal A method comprising: (a) loading the WIPI platform when power is supplied to the mobile communication terminal or an initialization command is input; (b) assigning and mapping a corresponding API of an operating system of the mobile communication terminal to an API defined in a handset application layer of the WIPI platform; (c) recognizing an event occurring in an operating system of the mobile communication terminal; And (d) mapping a first API, which is an API provided by an operating system of the mobile communication terminal, to a second API, which is an API provided by the WIPI platform, according to the recognized event, so that the operating system of the mobile communication terminal or the WIPI platform performs the event. And controlling to perform an operation corresponding to the.

As a result, the wireless Internet standard on the Symbian OS is developed based on a mobile communication terminal, which is a low-end system, and can effectively provide functions such as connection between smartphone parts and PDA parts, data services, and messaging. WIPI can be implemented.

Actively get the events that occurred. The processor 234 processes the received event on its own or delivers it to the matching unit 240. For example, if the received event is an SMS Push event, the processor 234 delivers the event to the matching unit 240 to provide the WIPI platform 250. The transfer unit 236 provides an information transfer path from the event processor 230 to the mapping unit 240.

The mapping unit 240 allocates and manages a corresponding API of the Symbian OS 260 which is an operating system of the mobile communication terminal to an API defined in the Handset Application Layer (HAL) of the WIPI platform 250. In addition, the mapping unit 240 maps the API provided by the Symbian OS 260 which is an operating system of the mobile communication terminal and the API provided by the WIPI platform 250 according to the event received from the event processing unit 230. The symbian OS 260 or the WIPI platform 250, which is an operating system of the OS, performs an operation corresponding to an event that has occurred. The operation of the mapping unit 240 depends on the type of event and the service execution command received from the user. Types of events are processed by the WIPI platform 250, such as events in which service processing is initiated by the Symbian OS 260, such as call inflow notifications, SMS reception notifications, alarms, media data playback, and data transmission.

The mapping unit 240 converts the transmission target data packet received from the WIPI platform 250 into a format suitable for the transmission API provided by the symbian OS 260, and then calls the transmission API provided by the symbian OS 260 to convert the data packet. The transmitted data to an external device as a destination (S410). At this time, the mapping unit 240 generates and manages a transmission record (identification information of data and an address of an external device as a destination) for the transmitted data packet. The event processor 230 monitors the communication server of the symbian OS 260 to determine whether a data reception event has occurred, and transmits the data reception event to the mapping unit 240 through IPC communication (S420).
