    摘要: A method and apparatus for providing an MBMS service to a plurality of cells in a mobile communication system are provided. In a mobile communication system including an RNC for providing an MBMS service and a plurality of Node Bs connected to the RNC, for providing the MBMS service to UEs within a plurality of cells. The RNC is configured to have a plurality of lower-layer entities corresponding to the cells. An RLC and PDCP entity that area common to the cells, receive MBMS data from an upper layer and transmit, upon receiving a request from one of the lower-layer entities, the MBMS data to the lower-layer entity. Therefore, the RNC can provide the MBMS service more efficiently, and unnecessary consumption of system resources is reduced.

    摘要: 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.

    摘要: 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.

    摘要: A method for selecting a cell by a user equipment (UE) to receive a Multimedia Broadcast/Multicast Service (MBMS) service in a mobile communication system which supports the MBMS service with different frequency allocations (FAs) in the same area. In the method, a radio network controller (RNC) transmits information on an MBMS cell to the UE, and the MBMS cell information includes an MBMS offset for guaranteeing priority for cell reselection to the MBMS cell. The UE performs cell reselection using the MBMS cell information and receives the MBMS service from the reselected cell.

    摘要: A method for enabling a user equipment (UE) to recover from a multimedia broadcast/multicast service (MBMS) data error in a mobile communication system. The mobile communication system includes a radio network controller (RNC) and at least one cell for transmitting MBMS data to at least one UE according to a control operation of the RNC. The RNC transmits first control information to UEs located in each cell. Each of the UEs receives the first control information and the MBMS data. When an error in the received MBMS data is detected, the RNC is notified that an MBMS data reception error has occurred. Response information associated with the MBMS data reception error is transmitted from the UE to the RNC. The UE determines whether control information contained in the response information matches the first control information. The MBMS data reception error is recovered from, according to a result of the determination.

    摘要: A method and apparatus for transmitting and receiving MBMS control information in an MBMS mobile communication system are provided. An RNC transmits MBMS control information for an MBMS service on an MCCH mapped to one of a plurality of CCPCHs available in a cell of the mobile communication system, and transmits a paging message on a logical channel mapped to each of the CCPCHs. Here, the paging message requests reception of the MBMS control information. A UE monitors one of the plurality of the CCPCHs, receives the paging message on the monitored CCPCH, switches to the CCPCH having the MCCH, and receives the MBMS control information on the switched to CCPCH. Therefore, resource consumption is minimized in transmitting MBMS control information in a cell and the reception reliability of the MBMS control information in the UE is increased.

    摘要: A mobile communication system supporting an MBMS service includes a Node B having a plurality of transport channels and at least one UE communicating with the Node B. The Node B selects a transport channel for MBMS control information among a plurality of transport channels mapped to a secondary common control physical channel; transmits a system information block indicating the selected transport channel to a cell area where UEs are located, using a primary common control physical channel; and transmits the MBMS control information to the cell area using the selected transport channel. The UE receives a system information block indicating a transport channel selected to transmit MBMS control information among a plurality of transport channels mapped to a secondary common control physical channel, over a primary common control physical channel; receives the MBMS control information over the selected transport channel among the plurality of the transport channels, using the system information block; and receives the MBMS service using the MBMS control information.
