  • Patent number: 8310974
    Abstract: An apparatus and a method for providing a MultiCast and BroadCast Service (MCBCS) in a Broadband Wireless Access (BWA) system are provided. The method includes receiving a message comprising information relating to a broadcast channel which carries a service guide, from a Base Station (BS), receiving service guides relating to one or more service providers over the broadcast channel using the information, when the received service guides are fragmented service guides having a certain size, generating a unified service guide by reassembling the fragmented service guides and when one service provider is selected, filtering only a service guide of the selected service provider in the unified service guide and displaying the filtered service guide in a display. Thus, the channel transition time can be reduced.

  • Publication number: 20120263301
    Abstract: A method and apparatus for transmitting/receiving encryption information in a mobile broadcast system providing broadcast service (BCAST) are disclosed. In the mobile broadcast system, a broadcast (BCAST) Service Distribution/Adaptation (BSD/A) unit comprises a transmitter for transmitting a Registration Key Material (RKM) request message for requesting delivery of an RKM for registration of the BCAST service of a terminal to a BCAST Subscription Management (BSM) unit managing subscriber information of the terminal, and a receiver for receiving an RKM request response message from the BSM unit. The RKM request message includes an identifier (ID) of the BCAST service, and the RKM request response message includes the ID of the BCAST service and the RKM. The transmitter transmits a Long-Term Key Message (LTKM) request message for requesting delivery of an LTKM provided to the terminal during subscription of the BCAST service to the BSM unit.

  • Patent number: 8285330
    Abstract: A method for HARQ reordering in Enhanced Uplink Dedicated Channel of WCDMA system includes following steps: locating the soft combination buffer in the Node B and the reordering buffer in the SRNC; locating the HARQ entity in the Node B; locating the reordering queue distribution entity, the reordering entity and the disassembly entity in the SRNC. This invention adopts the separation technology of the soft combination buffer and the reordering buffer, the separation model can not only ensure the diversity gain, but also reduce the receiving delay and save the buffer space. Three mechanisms (timer mechanism, window mechanism and SBI mechanism) are proposed to prevent the blocking of the reordering buffer, which degrades the blocking to the least level, improves the receiving efficiency and the system performance. Aiming at the SBI mechanism, the invention proposes the new DCH data frame structure on the Iub interface and the Iur interface.

  • Patent number: 8249587
    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.

  • Patent number: 8000303
    Abstract: A method and an apparatus are disclosed for applying frequency layer convergence (FLC) to connected mode user equipments (UE) having no dedicated channel for a multimedia broadcast/multicast service (MBMS) service in a mobile communication system employing a Code Division Multiple Access (CDMA) scheme. The method and apparatus prevent uplink signaling congestion which may occur when the UEs located in non preferred frequency layers (NPL) of the MBMS service move to a preferred frequency layers (PL) when a MBMS service session starts. If the MBMS service session starts in a situation of applying the FLC, a radio network controller (RNC) notifies the UEs desiring to receive the MBMS service and located in NPLs for the MBMS service of FLC information including a PF value and a timer value, with reference to the number of the NPL UEs joining the MBMS service.
