  • Patent number: 7107082
    Abstract: The present invention is related to a method of exchanging data between mobile phones through an inter-working function or proxy inter-working function service. The method includes a first step in which as a transmitting user manipulates a keypad of a transmitting mobile phone, the transmitting mobile phone enters transmission mode. At a second step, as a receiving user manipulates a keypad of a receiving mobile phone, the receiving mobile phone enters reception mode. Thereafter, the transmitting and receiving mobile phones are operated in data exchange mode for transmitting data from the transmitting mobile phone to the receiving mobile phone. Finally, data transmission from the transmitting mobile phone to the receiving mobile phone is completed.

  • Patent number: 6975724
    Abstract: A folder type mobile communication terminal includes a first housing and a second housing hingedly connected to the first housing. The second housing includes a second knuckle on the rotation axis where the second knuckle defines an opening hole inside thereof for insertion of a connection cable, a second hinge aperture formed in the axial direction of the rotation axis to allow the connection cable to insert therethrough, a projecting part at one end, and a structure at the opposite end which allows installation of a hinge spring assembly. The first housing includes first knuckles formed at both ends, where the first knuckles define a first hinge aperture that is directed to the direction of the second hinge aperture, and a first slot formed in the bottom of one of the first knuckles to enable the connection cable to insert therethrough.

  • Patent number: 6914891
    Abstract: A method of entering and modifying user data of a mobile communication terminal in a physically remote manner is provided A call is made from a mobile communication terminal to a computer or from a computer to a mobile communication terminal. Here, if a typical voice call or a simple data service call is connected, necessary data cannot be entered into the right memory area of the mobile communication terminal where said data have to be stored. In the present invention, a separate remote data update mode is set up and data and commands for transmission and entry of data are transmitted and received in this mode. According to the present invention, such data which cannot be entered by users in a direct manner to a mobile communication terminal as animation data or image data which are used for display on mobile communication terminal screen, melody data which are used for a ring tone for mobile communication terminal, game programs which are useable in mobile communication terminal, etc.
