    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: an Disclosed are a method and an apparatus for providing a PoC service in a radio communication system supporting a BCAST service. For the PoC service in the radio communication system supporting the BCAST service, a first terminal joining the PoC service through the BCAST service transmits user data for the PoC service over an uplink dedicated bearer, and the user data reach a PoC server, which controls the PoC service, over the uplink dedicated bearer. The PoC server transmits the user data to a BCAST server controlling the BCAST service and, from the BCAST service server, the user data reach plural second terminals joining the PoC service over a downlink shared bearer. In this way, radio resources can be efficiently used when the PoC service is performed in a random area, and an a BCAST service operator d a PoC service operator is provided.

    摘要: A communication system includes a shared channel occupied by a plurality of user equipments (UEs) and spread with a plurality of channelization codes to transmit user data, and a plurality of control channels for transmitting control information related to the shared channel in order to enable the UEs to receive the shared channel signal. The system generates a plurality of control channel sets by classifying the control channels into a predetermined number of control channels, and assigns the control channel sets so that each of the UEs monitors a particular control channel set among the control channel sets. Upon detecting necessity to modify a control channel set to be assigned to a particular UE among the UEs, a Node B determines to modify a control channel set assigned into the UE to a new control channel set at a predetermined point of time to come. After determining to modify the control channel set, the Node B transmits an indicator indicating expected modification of the control channel set and information on the control channel set to be modified to the UE over a downlink.

    摘要: A method and apparatus for performing a L3 handover between CNs in a packet-switched network are provided. When a UE moves from an old RAN to a new RAN, the UE sends a measurement report message including cell information to the old RAN. The old or new RAN determines whether to perform a L3 handover. If the L3 handover is required, a tunnel is established between the new RAN and a new CN. The UE performs a handover from the old RAN to the new RAN, without establishing a tunnel between the new RAN and an old CN. Upon detection of the movement of the UE, the new RAN sends a L2 handover complete message to the old RAN. After moving to the new RAN, the UE acquires a new IP address, performs the L3 handover, and communicates with the new CN through the new RAN.
