  • Patent number: 7751403
    Abstract: An apparatus and method for selectively combining broadcast data packets from a plurality of cells in a user equipment (UE). A selective combiner stores a received broadcast data packet in a buffer if a sequence number of the broadcast data packet received from the plurality of cells does not fall within a reception window, and stores the received broadcast data packet in the buffer if a sequence number of the received broadcast data packet falls within the reception window but has not been stored in the buffer. The selective combiner updates the reception window if a sequence number of the received broadcast data packet does not fall within the reception window, and discards the received broadcast data packet if a sequence number of the received broadcast data packet falls within the reception window but has been stored in the buffer.

  • Patent number: 7693112
    Abstract: An apparatus and method for providing multimedia broadcast and multicast services in a CDMA (Code Division Multiple Access) mobile communication system. The apparatus and method enable a common MBMC (Multimedia Broadcast/Multicast Control) layer to be allocated between a plurality of cells, enable MBMC layers to be classified on the basis of types of services, and use the classified MBMC layers. That is, individual MBMC layers do not have to store large-capacity data because a unique service or transmission rate in each of cells is based on a slow rate, and the individual MBMC layers corresponding to respective cells process a service requiring complex scheduling. Moreover, the apparatus and method enable the same information to be provided to a plurality of cells and enable a streaming-type service to be processed in a common MBMC layer commonly used in the cells.

  • Patent number: 7664503
    Abstract: A method of signaling bearer connection on Iu interface for MBMS service, includes the following steps: (a) RNC receives a MBMS Notification message for a certain MBMS service from SGSN; (b) RNC constructs a MBMS Service Request message according to the contents of the notification; (c) RNC sends a SCCP Connection Request message to SGSN, requests to establish a SCCP signaling connection, and then waits for a reply; (d) RNC receives a SCCP Connection Confirmation message from SGSN. This invention solves the problem of signaling connection on Iu interface after MBMS service is introduced into the existing mobile communication system. The connection mode provided in this invention can reasonably utilize network resources, effectively reduce signaling congestion on Iu interface and reduce modifications to the existing Iu interface message.

  • Patent number: 7636332
    Abstract: A multimedia broadcast/multicast service (MBMS) service and a method and apparatus for maintaining congestion and a signal transfer load of a cell at a suitable level when a session of the MBMS service is terminated in a frequency layer convergence (FLC) situation in which the MBMS service is provided in a preferred frequency layer (PL). When a session of the MBMS service is terminated, a radio network controller (RNC) determines if a cell selection is required in UEs, desiring to receive the MBMS service located in the PL cell, by using a start time of a new session and load levels of a current cell and other cells, and sends, to the UEs, explicit cell selection indication information along with session stop information according to a determination result. Therefore, the congestion and signal transfer load of the cell can be maintained in the suitable level.
