CONSTITUTION: An RF(Radio Frequency) unit(140) converts and filters a signal received through an antenna, and an RF(Radio Frequency) unit up-converts and filters the signal outputted from a control unit(100). A memory(150) stores plural kinds of data depending on the use of terminal or each kind of program for operating a mobile communication terminal. The memory downloads official authenticate data from a service providing server and stores the downloaded data. The memory stores the program having the function for selecting and using the official certificate according to the request of a user.

Description

Handheld mobile phone which has functions that sends and receives certificate for the multiple purposes}

Existing portable mobile terminal has a function such as issuing a certificate of the terminal user's own for wireless Internet commerce and store in the terminal. However, as the society develops and becomes more complex, there may be a need to receive and use certificates for others for various purposes. In the conventional portable mobile phone terminal, a certificate of a third party using its own certificate is transmitted to a third party, a third party's certificate is received and stored, or one of the third party certificates stored in such a manner is requested. This function is not provided.

In the conventional portable mobile phone terminal, a certificate of a third party using its own certificate is transmitted to a third party, a third party's certificate is received and stored, or one of the third party certificates stored in such a manner is requested. This function is not provided.

As described above, the existing portable mobile terminal has not been able to transmit or receive public certificate data to another person. The present invention provides a function for transmitting and receiving the authentication certificate data from the portable mobile phone terminal to another portable mobile phone terminal in order to solve this problem. When a public certificate data is received, it is stored in a memory and is a portable mobile terminal having a user interface that can use it.

By using the portable mobile phone terminal, it is possible to transmit and receive the public certificate data stored in the terminal with another terminal may be a variety of additional services using the same.

As described above, since the present invention can transmit and receive the public certificate data in the portable mobile phone terminal, if the data transmission technology is further developed in the future, it will enable a variety of services using the public certificate of others.

The present invention for achieving the above object has the following functions.

First, it has a function of transmitting the embedded certificate data to another mobile phone terminal. For this function, if the terminal has a public certificate to be transmitted, the procedure for converting it into a standard format irrespective of the model of the portable mobile terminal and the text message transmission protocol (IS-637 and its compatible protocol) or WAP (Wireless) Application Protocol) has a procedure for transmitting data using a data transmission protocol. Secondly, it has a function of receiving public certificate data through a specific data transmission protocol. For this function, the portable mobile terminal checks the received public certificate data to identify the public certificate data, converts the identified public certificate data into a format suitable for each mobile mobile device, and stores the data in the memory. Procedures and procedures that reflect them in the user interface.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, numerous specific details are set forth, such as a specific configuration, which are provided to assist in a more general understanding of the present invention, and the present invention may be practiced without these specific details. It is self-evident to those who have.

In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. The above-mentioned objects, features and advantages will become more apparent from the following detailed description in conjunction with the accompanying drawings.

1 is a schematic block diagram of a mobile communication terminal according to an embodiment of the present invention.

The control unit 100 controls the overall operation of the mobile communication terminal, performs a control operation for editing a call, a phone number, and sending and receiving mail according to a user's request, and for receiving a user's selection according to an embodiment of the present invention. Control the operation.

The display unit 110 may be configured as an LCD (Liquid Crystal Display) and the like, and outputs various display data according to the status information and the use mode of the terminal.

The voice processor 130 outputs a digital signal by processing a voice input through a microphone, and converts the data received through the antenna into an analog signal and outputs the analog signal.

The RF unit 140 down-converts and filters the signal received through the antenna and outputs the signal, and up-converts the signal output by modulating the CDMA (CODE DIVISION MULTIPLE ACCESS) from the controller 100. CONVERTING) and filter and transmit to the base station through the antenna.

The memory 150 stores various programs for operating the mobile communication terminal and a plurality of data according to the use of the terminal. In particular, the memory 150 requests, downloads and stores the public certificate data to the service providing server according to an embodiment of the present invention. It has a built-in program with the function to select and send the stored public certificate according to the user's request.

FIG. 2 shows a schematic operational sequence of the program embedded in the memory of FIG. 1 receiving, storing and using the public certificate data in accordance with the present invention.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to FIG. 2. In order to develop a portable mobile phone terminal according to the present invention, first, when a public certificate data is received, it should be stored in a database in a memory and provide a convenient method for the user to select and use. It also includes the ability to send public certificate data that you want to other users.

In this manner, the user of the portable mobile phone terminal can exchange authorized certificate data between the terminals.
