  • Patent number: 7969938
    Abstract: A method and apparatus for notifying a UE of the PFLs of MBMS services in a new cell when the UE moves from an old cell to a new cell in a CELL_DCH state in the case of FLC are provided. An SRNC informs the UE of the PFLs of UE-joined MBMS services in the new cell. If the new cell is managed by a DRNC, the DRNC informs the SRNC of the PFLs of the UE-joined MBMS services and the SRNC transmits the PFL information to the UE so that the UE can move to a corresponding PFL.

  • Publication number: 20100262826
    Abstract: A first terminal subscribes to at least one service using a service guide in which information necessary for reception of each service is stored, and sends the service guide and an identifier (ID) of the subscribed service to a smartcard. The smartcard stores the service guide and the ID of the subscribed service, and sends the service guide and the ID of the subscribed service to a second terminal through a response message to a request message used for acquiring TBK information, received from the second terminal. The second terminal receives the response message by sending the request message to the smartcard, acquires TBK information corresponding to a service that the second terminal intends to play back, from the service guide depending on the subscribed service's ID included in the response message, and acquires the TBK by performing an authentication process using the TBK information.
