  • Patent number: 7236474
    Abstract: An apparatus for reporting downlink channel quality in a high-speed packet communication system. A channel analyzer measures downlink channel quality from a received reference channel signal. A controller determines whether a current TTI (Transmission Time Interval) is a TTI corresponding to a multiple of a first TTI or a TTI corresponding to a multiple of a second TTI. If the current TTI is a TTI corresponding to a multiple of the first TTI, the controller determines CQ (Channel Quality) refreshment information for a downlink channel received from the Node B based on the measured downlink channel quality, and if the current TTI is a TTI corresponding to a multiple of the second TTI, the controller determines CQ refinement information for the downlink channel based on the measured downlink channel quality.

  • Publication number: 20070107018
    Abstract: A method, apparatus and system are provided for controlling a scene structure of a mobile terminal for receiving and displaying data streams in a mobile broadcast system. When logical channels are multiplexed into one physical channel, the multiplexed channels are sequentially decoded and are displayed on an image. A channel circulation scene alternately displays the channels on one image in designated order. In a combination scene structure, a new node is added to a conventional Lightweight Application Scene Representation (LASeR) technology. To compose a scene, fields for time information and scene transition effect are provided. A delay time due to a channel change is reduced. A multi-channel image is effectively provided to address a problem when a user retrieves service content while directly switching a channel. The terminal dynamically composes the multi-channel image using stream source node information from a service provider without an additional mosaic channel.

  • Publication number: 20070093202
    Abstract: A roaming service method in a mobile broadcasting system and a system thereof are provided. A terminal receives a service guide from a corresponding visited service provider (Visited SP) when the terminal moves to a roaming area. The terminal transmits a roaming request message for requesting a purchase item allowable for individual services to a home service provider (Home SP) based on the received service guide. Upon receipt of the roaming request message, the Home SP negotiates roaming availability and allowable scope for each individual service with the Visited SP where the terminal is located, based on the roaming request message. The Home SP transmits the roaming availability and allowable scope for the individual service, negotiated with the Visited SP, to the terminal.

  • Publication number: 20070093263
    Abstract: An apparatus and method for managing a preference channel are provided which can reduce a delay time when a channel change is made between preference channels, by storing a preference channel directly selected by a mobile terminal user in a mobile broadcast system. A mobile terminal receives and demultiplexes multiplexed logical channels on which data streams are transmitted from a service provider through a communication network. Preference channels of the demultiplexed logical channels are dynamically allocated to decoding buffers using stored information. A decoding time at which data of the decoding buffers is accessed and decoded is computed using reference information. A decoding operation is performed at the computed decoding time, and decoded channel-by-channel elementary streams are stored in a memory. The decoded channel-by-channel elementary streams stored in the memory are displayed on a screen of the mobile terminal.

  • Patent number: 7200124
    Abstract: An RNC determines parameters available for measurement of a synchronization signal and second Node B information from a second Node B, transmits the determined parameters to a first Node B during radio link setup and to a UE during radio bearer setup, and transmits parameter selection information to the first Node B and the UE, if it is recognized that measurement of the synchronization signal and the second Node B information is necessary. The first Node B changes a position of a downlink time period over which a downlink channel is transmitted from the first Node B to the UE and a position of an uplink time period over which an uplink channel is transmitted from the UE to the first Node B, according to parameters selected from the parameters. The UE receives the synchronization signal and the second Node B information in the remaining time periods except the changed downlink time period and the changed uplink time period among the plurality of time periods.

  • Patent number: 7197333
    Abstract: A paging system and method for use in a multimedia/broadcast multicast service (MBMS). The paging system checks a paging indicator channel of a UE (User Equipment), and determines whether there is a paging signal associated with a broadcast service. If the paging signal associated with the broadcast service is detected, the paging system recognizes the channel information indicative of the paging fact, checks paging information included in an ID for differentiating between the broadcast service and other broadcast services and a paging response indicator adapted to determine a transmission channel scheme of the broadcast service, establishes a radio link, and receives control information using the radio link. The base station controller adapted to manage a cell including the UE transmits MBMS transmission scheme information to the UE in advance using the paging information, resulting in maximum use efficiency of RRC (Radio Resource Controller) resources.

  • Publication number: 20070060138
    Abstract: An apparatus and method for controlling a data rate by a user equipment (UE) that receives a scheduling command for uplink data transmission from a non-serving Node B in a mobile communication system that transmits packet data over an uplink are provided. A scheduling command receiver receives a down command for decreasing an allowable data rate of the UE from radio link sets (RLSs) of the non-serving Node Bs. A down command reception counter counts the number of down commands received from each of the RLSs for a predetermined hysteresis period. A down command execution counter counts the number of down commands executed for the hysteresis period. A down command execution decision unit compares the number of received down commands with the number of executed down commands, and determines whether to execute the down command according to the comparison result.
