  • Patent number: 7526287
    Abstract: A method for ciphering MBMS (Multimedia Broadcast/Multicast Service) data in a wired/wireless communication system is provided. The MBMS service enables the same service or desired services to be provided to a number of users. In the ciphering method, a ciphering key for encoding MBMS data is previously provided to an authorized UE, and the authorized UE is informed of when MBMS data encoded using the ciphering key is to be transmitted, thereby preventing unauthorized UEs from illegally receiving the MBMS service.

  • Patent number: 7526091
    Abstract: A method for minimizing overhead occurring caused by control information for encryption performed to protect MBMS data for an MBMS service in a mobile communication system. This method is implemented by distinguishing a case in which control information used for encryption is updated from another case in which the control information used for encryption is not updated, and transmitting different control information according to the distinguishment result. That is, when the control information used for encryption is not updated, only minimized control information is transmitted, and when the control information for encryption is updated, the entire updated control information is transmitted. Accordingly, the amount of control information transmitted along with MBMS data is minimized, contributing to an increase in the amount of MBMS data transmitted per unit time.

  • Patent number: 7515922
    Abstract: A control message transmitting/receiving method in an MBMS-supporting mobile communication system. In the present invention, an RNC periodically transmits control messages related to MBMS RB setup to UEs. Thus, although a UE initially fails to receive an intended MBMS service, it can set up an MBMS RB by receiving a related retransmitted control message. Also, the RNC periodically provides information about ongoing MBMS services on a cell basis so that a UE can decide whether its requested MBMS service is in progress and request information required to set up an MBMS RB for the MBMS service to the RNC by individual signaling.

  • Patent number: 7512086
    Abstract: Disclosed is an uplink random access procedure in an NB-TDD (Narrow Band Time Division Duplexing) system. To achieve an acknowledgement for data transmission from a UTRAN (UMTS Terrestrial Radio Access Network), a UE selects one of a plurality of sync codes by which the UTRAN identifies UEs that request data transmission and transmits the selected sync code in a time slot of a sub-frame to the UTRAN. Then, the UE receives the sync code information, information about the arrival time of the sync code, time update information indicating a variation in the transmission time of data, and power information indicating an adjustment to a power gain in the UE from the UTRAN on an FPACH (Fast Physical Access Channel). The UE transmits the data on a P-RACH (Physical Random Access Channel) mapped from the FPACH according to the time update information and the power information.

  • Publication number: 20090069003
    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.

  • Patent number: 7499435
    Abstract: A method and apparatus for enabling partial combining on a Multimedia Broadcast/Multicast Service (MBMS) service are provided where a radio network controller (RNC) specifically informs a user equipment (UE) whether an MBMS service signal of the current cell is combinable with the same MBMS service signals received from different cells for each individual service or timing, through an MCCH or an MSCH, which is a type of a logical channel for an MBMS service, in a Uu interface. The UE combines the MBMS service signals transmitted from the different cells, thereby obtaining a gain in terms of utilization of transmission power and radio resources.

  • Patent number: 7496075
    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.

  • Patent number: 7480519
    Abstract: A method and apparatus are provided for enabling a UE to perform accurate and efficient cell reselection in a cellular mobile communications system. If reselection to the same cell is repeated, the UE releases itself from a high-speed UE state or excludes the number of reselections to the same cell from the number of cell changes counted for a duration set for deciding as to the high-speed UE state, according to a ping-pong duration threshold and a ping-pong occurrence number threshold. The UE uses a non-scaled down cell reselection time limit in a non-high-speed UE state, and a scaled-down cell reselection time limit in the high-speed UE state. Thus, the UE reselects to a non-serving cell having the highest ranking continuously for the cell reselection time limit.

  • Patent number: 7450547
    Abstract: Disclosed is a method for resuming header decompression by receiving multimedia broadcast/multicast service (MBMS) packet data having compressed headers in a mobile communication system providing the MBMS. The method includes the steps of detecting a moving of user equipment (UE) receiving the MBMS into a new cell from an old cell, copying and storing old header decompression context information used in the old cell, initializing a dynamic part to decompress headers of packet data for the MBMS and waiting for an IR-DYN packet until the IR-DYN packet has been received in the UE, in order to update the old header decompression information, creating a new header decompression context through updating the old header decompression information by using the IR-DYN packet when the IR-DYN packet has been received in the UE, and decompressing the headers of the packet data for the MBMS transmitted from the new cell by using the new header decompression context.

  • Patent number: 7450545
    Abstract: An apparatus and method determines soft handover in a Code Division Multiple Access (CDMA) mobile communication system supporting a Multimedia Broadcast Multicast Service (MBMS) service. In the CDMA mobile communication system supporting an MBMS service, when a User Equipment (UE) moves to a region where it can receive data from a plurality of Node Bs, the UE determines by itself whether to perform soft combining on MBMS data received from the Node Bs. Therefore, even though an MBMS user moves from an existing cell to a new cell, the MBMS service is stably provided, contributing to the convenience of the user.

  • Patent number: 7443813
    Abstract: A notification method for informing a UE of an existence or absence of control information for an MBMS in a mobile communication system supporting the MBMS. In the method, the UE receives a notification indicator channel independently reporting the existence of the control information for the MBMS, confirms at least one notification indicator of the notification indicator channel, thereby confirming the existence of the control information relating to the requested MBMS. Further, a method is proposed, which can minimize an alarm due to other MBMSs.
