Disclosed is a mobile communication terminal having a subscriber identity module (SIM) card. The mobile communication terminal includes a memory unit (130) for storing use-history information of the SIM card (180) inserted into the mobile communication terminal according to a subscriber identity number of the inserted SIM card, and a controller (140) for determining the subscriber identity number of the inserted SIM card, determining whether a predetermined storage area corresponding to the subscriber identity number exists in the memory unit, and generating the predetermined storage area in the memory unit when the predetermined storage area does not exist in the memory unit. Further, it is possible to search the use-history information stored in a storage area corresponding to the subscriber identity number of each SIM card carried by a user. Therefore, the security for the use-history information of the SIM card can be ensured.

Disclosed is a method for manufacturing a preform for a photonic crystal fiber (PCF). The method includes the steps of (A) forming a dry gel having a cylindrical shape by forming a silica slurry obtained by mixing a monomer and a dimer and drying the slurry, and (B) forming air holes e.g. by drilling, having the desired size and arrangement through the dry gel, thereby easily regulating the size and arrangement of the air holes and manufacturing various shapes of the preform.

A password-encrypted key (PEK) is generated from a user-supplied password or other identifyting data and then used to encrypt the user's password. The encrypted password is stored in a user record on a server. At login a would-be user's password is again used to make a key, which is then used to decrypt and compare the stored encrypted password with the would-be user's password to complete the login. The successful PEK is stored in a temporary session record and can be used to decrypt other sensitive user information previously encrypted and stored in the user record as well as to encrypt new information for storage in the user record. A public/private key system can also be used to maintain limited access for the host to certain information in the user record.

A method of accessing and processing a file stored in a sub-memory (135) of a portable terminal (Fig.1) including the sub-memory (135) and an internal memory (133) capable of storing mass storage data. The method includes storing a file system menu of the sub-memory in the internal memory (315) during a boot-up operation (313), displaying the file system menu when shifting into a file access mode for the sub-memory from a waiting mode, accessing file data selected from the file system menu and buffering the file data in the buffer of the internal memory (411,613) until the file data have a size corresponding to a predetermined upper limit value (413,615), processing the buffered file data (617), buffering data of the sub-memory in the buffer (423) until the data have a size corresponding to the upper limit value (427) when a quantity of buffered data becomes lower than a predetermined lower limit value (417) while processing the buffered file data, and repeating data processing and buffering procedures until a closing command is generated (419,429,625).

Disclosed is a method of processing a schedule alarm message in a portable terminal comprising analyzing a message when the message is received in the portable terminal in order to check whether the message includes schedule information, extracting the schedule information from the message and storing the schedule information if the message includes the schedule information, and registering the schedule alarm message in a receive message list. The method of processing a schedule alarm message in a portable terminal further comprises displaying a display window including items used for displaying the stored schedule information and an alarm time when the user confirms the schedule alarm message, allowing the user to correct the schedule information and to set the alarm time by using the items displayed in the display window, and registering the corrected schedule alarm message to a schedule alarm message list in response to a schedule alarm message registration request.
摘要:
An optical fiber cable and a method of fabricating the same are disclosed. The optical fiber cable includes at least one optical fiber including a core, which is an optical signal transmission medium, a clad surrounding an outer peripheral surface of the core, and a coating layer surrounding an outer peripheral surface of the clad. The optical fiber cable also includes an external sheath including a first layer having a predetermined thickness and a second layer made of polymer material and formed at an outer peripheral surface of the first layer through an extruding process and a waterproof member accommodated between the external sheath and the optical fibers. A plurality of recesses having a predetermined depth and a predetermined diameter are formed on the second layer.

Disclosed is an apparatus and a method for enabling sound data having a three dimensional stereo sound effect to be reproduced in a mobile communication terminal. A three dimensional stereo sound reproducing apparatus for a mobile communication terminal comprises: a memory for storing sound data having a three dimensional stereo sound effect; a sound processing unit for reading the sound data from the memory when an incoming call is generated or when a user requests reproduction of the sound data and for decoding the sound data without distortion of the three dimensional stereo sound effect, thereby outputting the sound data as a type of an analog signal; and a speaker for amplifying the analog signal and outputting the amplified analog signal as a type of an audible sound. Therefore, it is possible to obtain an excellent three dimensional stereo sound effect and an excellent performance in reproducing original sound.
