  • Patent number: 8116828
    Abstract: A current consumption controlling apparatus and method in a portable terminal are provided. The apparatus includes a first transceiver for outputting a signal indicative of a transmit burst time of a first communication system mode supported by the first transceiver to a second transceiver, and adjusting a gain of a power amplifier by receiving a signal indicative of a transmit burst time of a second communication system mode from the second transceiver; and the second transceiver for outputting the signal indicative of the transmit burst time of the second communication system mode to the first transceiver, and adjusting a gain of a power amplifier by receiving the signal indicative of the transmit burst time of the first communication system mode.

  • Patent number: 7330705
    Abstract: A method and apparatus for controlling a SAR (Specific Absorption Rate) in a mobile communication terminal. The SAR is controlled by adjusting a transmission power of a mobile communication terminal. The method for controlling the SAR in a mobile terminal includes the steps of checking a user-selected SAR control mode of the mobile terminal, setting a code value corresponding to a transmission power of the RF signal to a gain of the amplifier, wherein the code value is set to a first code value when the SAR control mode is a safe mode, or is set to a second code value when the SAR control mode is a normal mode, and amplifying the RF signal according to the gain of the amplifier, such that it controls a transmission power of an RF (Radio Frequency) signal by controlling a gain of an amplifier amplifying the RF signal.

  • Patent number: 7142807
    Abstract: A method of providing a Karaoke service to mobile terminals through wireless connection between them. The mobile terminals are grouped as a service group and one of them is designated as a master mobile terminal and the other mobile terminals as slave mobile terminals. The master mobile terminal is connected to a Karaoke service provider through a mobile communication network and controls service content to be received from the Karaoke service provider in all the mobile terminals of the service group. If the master mobile terminal transmits a play command to the slave mobile terminals, all the mobile terminals start to play Karaoke music according to the service contents.
