    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 of transmitting and receiving MBMS service availability information. To support the mobility of UEs receiving an MBMS service, an RNC transmits, to each of a plurality of cells under its control, an MBMS service availability message including service availability information and resource availability information regarding at least one MBMS service available in the cell. From the MBMS service availability message, a UE determines if a desired MBMS service can be received in a current cell currently or in the future. The UE requests the desired MBMS service or selects another cell capable of providing the MBMS service.

    摘要: A method and apparatus performs handover from an OFDM-based E-UMTS system to a CDMA-based UMTS system. A UE in communication with a PDN via the E-UMTS system, measures signal strength of the UMTS system, and sends a measurement report message indicating the measured signal strength to the E-UMTS system. A radio access network (E-RAN) of the E-UMTS system, determines whether to perform handover from the E-UMTS system to the UMTS system based on the measured signal strength. If the handover is to be performed, a core network (E-CN) of the E-UMTS system generates a PDP context and an MM context for the UE in response to a handover request from the E-RAN. The E-CN sets up a data tunnel for the UE to a GGSN of the UMTS system using the PDP/MM context. After setting up the data tunnel, the E-CN sends to the UE a handover command message including information on a radio bearer (RB) to be used by the UE to access the UMTS system. The UE accesses the UMTS system using the RB information. After accessing the UMTS system, the UE forwards user data for the UE via a data transmission path composed of the E-CN, the data tunnel, a SGSN, and a RAN of the UMTS system, between the PDN and the UE.

    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.
