Problems solved by technology

Since the broadcast and multicast timings are different in the respective cells, when handover is performed in an overlapping area between cells, continuous service cannot be ensured from the user's point of view, and QoS (Quality of Service) may degrade

Embodiment Construction

[0068] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings. Further, preferred embodiments of the present invention are disclosed in the following detailed description of the present invention. In addition, other embodiments of the present invention are explained in the description about the configuration of the present invention.

[0069] First, the conventional technology allows broadcast / multicast service information to be stored, scheduled and sent independently on a cell-by-cell basis, while the present invention allows a common MBMC (Multimedia Broadcast / Multicast Control) layer to be distributed among multiple cells, allowing The MBMC layers are classified according to the type of service, and the classified MBMC layers are used. That is, since the individual service in each cell or the transmission rate between cells is based on a low rate, the MBMC layer (dedicated MBMC layer) does not have to ho...

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. The apparatus and method can not only reduce an overhead of storage and processing devices but also minimize a time difference between broadcast and multicast timings of different cells, by enabling the common MBMC layer to commonly process MBMS information for the plurality of cells.

Description

technical field [0001] The present invention mainly relates to an apparatus and method for transmitting packet data in a CDMA (Code Division Multiple Access) mobile communication system, and particularly relates to an apparatus and method for providing multimedia broadcast / multicast services. Background technique [0002] With the development of the communication industry, services provided by the CDMA (Code Division Multiple Access) mobile communication system have evolved into multimedia multipoint communication services capable of transmitting large-capacity data such as packet data and circuit data, and voice services. A broadcast / multicast service that can provide data from one data source to multiple UEs (User Equipment) to support multimedia multipoint communication has been proposed. The broadcast / multicast service is divided into CBS (Cell Broadcast Service) mainly based on messages, and MBMS (Broadcast / Multicast Service) for supporting various multimedia such as re...
