  • Method of ciphering data and/or voice call to be transferred in mobile communication system and method of deactivating the ciphering
    Patent number: 7564975
    Abstract: A system and method of controlling ciphering of call information between a mobile communication terminal and a network initiates the transmission of a ciphering request from the terminal to the network. The network then transmits a ciphering authentication request message to the terminal and the terminal responds by transmitting a ciphering authentication response message to the network. The network then transmits a ciphering activation completion message to the terminal in accordance with the ciphering authentication response message. A system and method for controlling deactivation of ciphering of call information initiates transmission of a ciphering deactivation request from the mobile terminal to the network. The network then performs the ciphering deactivation and transmits a ciphering deactivation completion message to the terminal. Through these systems and methods, the user terminal controls ciphering and deciphering of call information instead of the network.

  • Method and apparatus of exchanging transfer parameters in a mobile communication system
    Publication number: 20040103201
    Abstract: A method and apparatus are provided for exchanging transfer parameters in a mobile communication system. A terminal may transfer a PDP context request message to a network. The PDP context message may include an XID tag for determining a transfer parameter value. The network receives the PDP context request message from the terminal and transfers a PDP context accept message to the terminal as acceptance.
