Due to the continuous development of information and communication technology, various types of wired communication infrastructure and wireless communication infrastructure are being established. As a result, conventional terminal devices incorporating information and communication technology are used in the initial single communication and single function (SCSF). Increasingly, single communication and multi function (SCMF) has been developed, and recently, multi communication and multi function (MCMF) has been limitedly attempted.

For example, a single communication single function mobile phone initially connected to a mobile communication network to provide a voice call function may be provided with a wireless Internet service in addition to the voice call through the mobile communication network, and / or download and play a game; and It has developed into a single communication multi-function such as downloading and playing MP3 files, and recently, a multi-communication multi-function has been attempted to add an infrared communication function to the mobile phone and use it for a financial settlement service.

However, in the case of the multi-communication multi-function as described above, there is a problem in that the interworking between the plurality of communication modules provided in the terminal device is not provided and thus not activated.

For example, in the case of the mobile phone equipped with the mobile communication function and the infrared communication function, the mobile communication is used for the voice call and the data communication service, and the infrared communication is used only for the financial settlement service. The function was not activated.

In order to solve the above problems and provide various application services, a method of interworking a plurality of communication modules provided in the terminal apparatus has been attempted. However, the conventional attempted communication module interworking method is to share data at an application program level.

For example, in the case of the mobile phone having a mobile communication function and an infrared communication function, a predetermined discount coupon is downloaded through a mobile communication network, and data on an application level in the form of using the discount coupon in a financial settlement service process using infrared communication. Only limited sharing was attempted.

In the future, in order to provide a variety of application services by providing a multi-communication multi-function to a terminal device in which information and communication technology is incorporated as described above, a plurality of communication modules provided in the terminal device should be interlocked in real time. It is difficult to provide real-time interworking between a plurality of communication modules as described above only by data sharing.

If the check result indicates that the program corresponding to the bridge function of the communication protocol stack cannot be downloaded to the terminal (1125), the server generates predetermined program loading error information and transmits the predetermined program loading error information to the terminal through the communication network. The process of downloading and loading the program corresponding to the bridge function of the communication protocol stack to the terminal is terminated.
On the other hand, if it is confirmed that the program corresponding to the bridge function of the communication protocol stack can be downloaded and mounted to the terminal (1125), the server downloads a predetermined program file designed to provide the bridge function of the communication protocol stack to the terminal.
