    • An apparatus and a method for changing a MultiCast and BroadCast Service (MCBCS) broadcasting channel in a Broadband Wireless Access (BWA) system are provided. The method includes, if an MCBCS initialization request message is received from an MCBCS server, sending a burst reservation request message for MCBCS burst allocation to one or more Base Stations (BSs) in a corresponding Multicast and Broadcast Service (MBS) zone, and if a burst reservation response message is received from at least one of the one or more BSs, sending a Resource Reservation (RR) request message for each channel to the at least one of the one or more BSs for establishing data channels for each channel broadcast by the MCBCS server. Accordingly, a channel transition delay time resulting from a user's channel change can be reduced.
    • 提供了一种用于在宽带无线接入(BWA)系统中改变MultiCast和BroadCast服务(MCBCS)广播信道的装置和方法。 该方法包括:如果从MCBCS服务器接收到MCBCS初始化请求消息,则将MCBCS突发分配的突发预留请求消息发送到对应的多播和广播服务(MBS)区域中的一个或多个基站(BS),如果 从所述一个或多个BS中的至少一个接收到突发预约响应消息,向所述一个或多个BS中的至少一个发送每个信道的资源预留(RR)请求消息,以建立每个频道广播的数据信道,由 MCBCS服务器。 因此,可以减少由用户的频道改变引起的频道转换延迟时间。

    • An apparatus and method for providing an interactive broadcasting service in a Broadband Wireless Access (BWA) system are provided. The method includes receiving content attributes, including a terminal interaction request time index information, and corresponding contents from a content provider; after transmitting the contents to a terminal, sending a burst allocation request message to a Base Station (BS) to allocate an uplink bandwidth to the terminal at the terminal interaction request time; and receiving interactive information from the terminal over the uplink bandwidth allocated to the terminal. The content provider or the service provider can request a response from a plurality of recipients through the MBS service, gather their responses, and reflect the gathered information in the contents.
