    • A system and method for de-registering a Broadcast/Multicast Service (CMCS) in a high-rate packet data system including an access network (AN) for performing radio communication with an access terminal (AT), a packet control function (PCF) for processing packet data communication, and a packet data service node (PDSN) connected to a BCMCS contents server (CS) via a packet communication network is provided. In the system and method, the access network receives a de-registration message for a release request of a BCMCS service from the access terminal. The access network transmits a BCMCS release message including BCMCS information with a release request, to the packet control function The packet control function transmits a BCMCS registration request message including the BCMCS information to the packet data service node. The packet data service node performs a release and accounting process on a corresponding BCMCS service based on the BCMCS information.
    • 一种用于在包括用于与接入终端(AT)进行无线电通信的接入网络(AN)的高速率分组数据系统中解除注册广播/组播服务(CMCS)的系统和方法,分组控制功能(PCF) 用于处理分组数据通信,并且提供经由分组通信网络连接到BCMCS内容服务器(CS)的分组数据服务节点(PDSN)。 在系统和方法中,接入网从接入终端接收用于BCMCS业务的释放请求的去注册消息。 接入网将包含BCMCS信息的BCMCS释放消息发送到分组控制功能。分组控制功能向分组数据服务节点发送包括BCMCS信息的BCMCS注册请求消息。 分组数据服务节点基于BCMCS信息对对应的BCMCS服务执行释放和计费处理。

    • A method for registering Broadcast/Multicast Service (BCMCS) in a mobile broadcasting system , a BCMCS server for providing a BCMCS service to an access terminal, and a mobile communication system connected to the BCMCS server. The access terminal exchanges information, necessary for BCMCS setup, with a BCMCS controller during a state wherein a session to the mobile communication system is set up. Upon receiving a BCMCS overhead from an access network, the access terminal transmits a message, including BCMCS identification information for a desired BCMCS service, to the access network. Upon receiving the message, the access network transmits a BCMCS connect setup message to a packet control function . Upon receiving the BCMCS connect setup message, the packet control function then transmits a registration message, including BCMCS information, to a packet data service node in the mobile communication system.
    • 一种用于在移动广播系统中注册广播/组播服务(BCMCS)的方法,用于向接入终端提供BCMCS服务的BCMCS服务器以及连接到BCMCS服务器的移动通信系统。 在与移动通信系统的会话建立的状态下,接入终端与BCMCS控制器交换BCMCS建立所必需的信息。 接入终端从接入网接收到BCMCS开销时,向接入网发送包括所需BCMCS业务的BCMCS识别信息的消息。 在接收到该消息时,接入网将BCMCS连接建立消息发送到分组控制功能。 在接收到BCMCS连接建立消息时,分组控制功能将包括BCMCS信息的注册消息发送到移动通信系统中的分组数据服务节点。

    • 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。
