The present invention is to modularize each functional unit of the mobile terminal, in particular, by connecting each module with a small number of connection pins, combining the data in a high-speed MDDI (MDDI) interface method in the state of consuming less power and blocking noise The present invention relates to a modular apparatus and a method of a portable terminal for improving the expandability of functions while reducing the size of the portable terminal.

The mobile terminal for mobile communication (MS: MOBILE STATION) moves freely in a service area formed by a registered base station or a corresponding base station (RAN: RADIO ACCESS NETWORK) of the mobile communication network (NETWORK). It is a high-tech wireless communication device that allows an individual to carry it anywhere and always carry it by wirelessly communicating with the desired party anytime, anywhere through the communication path established by monitoring, control and switching of the mobile switching center. .

The mobile terminal (MS) is for mobile communication, the time used for the actual communication is very small, and always moves to the mobile state for communication when it may occur.

In order to increase the utilization rate or utilization rate of the mobile terminal as described above is an additional service, the additional service increases the utilization rate of the mobile terminal and at the same time provides the applicability and convenience of real life.

The additional services include those developed and provided by a mobile communication service provider and those developed and provided by a mobile terminal producer. For example, the additional services developed and provided by the producer include a camera, a Bluetooth, a wireless LAN, a radio, Satellite TV reception, terrestrial TV reception, games, electronic calculators, calendars, etc., developed and provided by mobile communication service providers include voice messages, text messages, video messages, online games, wireless Internet, caller identification, etc. The additional services continue to be added with new and convenient features.

As described above, various additional service functions are newly developed and added, and in order to use the new functions added as described above, new mobile terminals must be replaced, equipment prices are expensive, and existing mobile terminals must be disposed of. There is a problem such as waste.

Therefore, it is necessary to add a plurality of additional services to the portable terminal when necessary, to facilitate the expandability, and to develop a portable terminal having a smaller overall size and less trouble.

Hereinafter, a structure of a mobile terminal for a mobile communication according to the prior art will be described with reference to the accompanying drawings.

1 is a functional configuration diagram of a general mobile communication system, and FIG. 2 is a functional configuration diagram of a mobile terminal according to an example of the prior art.

Referring to FIG. 1, a general mobile communication system will be described. A mobile terminal (MS) 10 wirelessly connects with a counterpart while moving freely in a service area formed by a base station (RAN) 20. To communicate.

In order for the mobile terminal 10 to wirelessly connect and communicate with the other party, the MSC 30 must analyze the call connection request signal and wirelessly connect with the other party via a communication path established by switching. do.

The mobile switching center 30 is a public network 50 when the communication counterpart is subscribed to another mobile communication system, a wired communication network, or a specific site (SITE) of the Internet (INTERNET) by analyzing a call connection request signal. To control the communication path.

The mobile communication system including the mobile switching center 30 provides a variety of additional services to the portable terminal, the additional services are processed by the server 40, the server 40 includes a database.

For example, when the mobile terminal 10 wants to access a specific site (SITE) on the Internet by using a wireless internet access supplementary service, the mobile terminal 10 wirelessly requests the call connection using a wireless internet access function added to the mobile terminal. The request is granted to the mobile switching center 30 through the base station 20. The mobile switching center 30 searches the database of the server 40 to determine whether it is a registered mobile terminal capable of receiving wireless Internet service. If the mobile terminal 10 is registered as a result of the check, the public network 50 is controlled to establish and establish an internet communication path.

That is, in order to access the wireless Internet by using a portable terminal, a corresponding functional unit for processing and transmitting wireless Internet data must be provided in the portable terminal, and if there is no functional unit, a new portable terminal needs to be replaced.
