  • Patent number: 10397867
    Abstract: A method of operating a user equipment includes setting a user equipment to enter a public safety mode, converting the user equipment to an idle state when the user equipment enters the public safety mode, and temporarily converting the user equipment from the idle state to a partial wakeup state during the public safety mode. A public safety carrier searching is performed for device-to-device (D2D) communication between the user equipment and a neighboring equipment during the partial wakeup state. The method may efficiently support the D2D communication and reduce power consumption by changing the state of the user equipment into the idle state when entering the public safety mode and temporarily changing the user equipment into the partial wakeup state for public safety carrier searching.

  • Patent number: 7236740
    Abstract: A method and apparatus for retransmitting data in a mobile communication system wherein a receiver determines whether an initial data block received from a transmitter has an error. Upon detecting an error from the initial data block, the receiver estimates a current channel state and determines a retransmission frequency and a power level of the initial data block according to the estimated current channel state. Thereafter, the receiver transmits a retransmission request message of the initial data block together with the determined retransmission frequency and the determined power level to the transmitter. The transmitter retransmits the initial data block as many times as the retransmission frequency at the requested power level. The receiver then determines whether the retransmitted data blocks have errors, and provides the retransmitted data blocks to an upper layer upon failure to detect errors from the retransmitted data blocks.

  • Patent number: 7162267
    Abstract: A composite cellular terminal providing various service options issues different call termination alert tones and different call termination display messages according to types of terminated calls. The cellular terminal sets and stores the call termination alert tones and the call termination display messages according to those service options which are available for the composite cellular terminal. Upon reception of a paging message, If the terminal recognizes the service option contained within the paging message, the terminal then retrieves a call termination alert tone corresponding to the recognized service option and generates the call termination alert tone. The terminal then retrieves a call termination display message corresponding to the recognized service option and displays the read call termination display message.

  • Patent number: 7155211
    Abstract: A method and system for providing a picture as caller ID (Identification). In a mobile communication system having a first mobile station (MS) on a calling side, a second MS on a called side, and a base station (BS) and an MSC that enable communication between the first and second MSs, the MSC has a storage component that stores picture information of each MS. The MSC receives a SETUP message from the first MS via the BS during a call attempt by the first MS, checks whether the picture information of the first MS is stored in the storage component in response to the SETUP message, and transmits the picture information of the first MS to the second MS so that the picture information of the first MS can be displayed as the caller ID on a display of the second MS, if the picture information of the first MS is stored in the storage component of the MSC.

  • Patent number: 7127260
    Abstract: Disclosed is a method for determining a paging alert mode of a mobile terminal in a mobile communication system. The mobile terminal determines whether there exists a sub-BTS, depending on a broadcasting channel message provided in a cell formed by a main BTS. When the sub-BTS exists, the mobile terminal monitors receipt of a beacon paging group frame from the sub-BTS, and upon receipt of the beacon paging group frame, changes the paging alert mode to a predetermined paging alert mode.

  • Patent number: 6724742
    Abstract: There is provided a method for controlling gated transmission of a dedicated channel signal in a W-CDMA communication system. In the W-CDMA communication system, a dedicated control channel has 15 slots in one frame, each slot includes a TFCI bit, a TPC bit, and a pilot bit, and the dedicated control channel and a dedicated data channel for transmitting packet data are multiplexed prior to transmission. In an embodiment of the present invention, a base station transmits to a mobile station a gated transmission command message including a gating rate and a gated transmission start time for gated transmission of the dedicated control channel signal, if no data exists on the dedicated data channel for a predetermined period of time. Then, the base station transmits the dedicated control channel signal in a gated mode at the gated transmission start time set in the gated transmission command message.
