    • The present invention relates to a mobile multicast system and a method thereof, and more particularly to a network-based mobility multicast system and a method thereof. The system according to one embodiment of the present invention is the mobile multicast system for supporting the network-based mobility comprising: access points which communicate with mobile terminals within an access network through a wireless channel, obtains layer 2 addresses of the terminals, and provides the obtained layer 2 addresses of the terminals; management parts which control a handover of each terminal included in the access points, transmit multicast packets to be provided to the terminals, and are provided according to the access points; a router which receives the multicast data through the network, and transmits the multicast packets to the terminals for receiving the multicast data; and a mobile control server which obtains position information of the terminals from the management parts, transmits a query message for determining the reception of the multicast data to each of the management parts so as to confirm whether the terminals join the multicast when receiving the query message from the router, and controls setting of a tunnel between the router and the management part for transmitting a membership report message when receiving the membership report message for joining the multicast.
    • 移动组播系统及其方法技术领域本发明涉及移动组播系统及其方法,更具体地涉及一种基于网络的移动性组播系统及其方法。 根据本发明的一个实施例的系统是用于支持基于网络的移动性的移动组播系统,包括:通过无线信道与接入网内的移动终端通信的接入点,获得终端的2层地址,并提供 获得的层2地址的终端; 控制接入点中包含的每个终端的切换的管理部件,发送要提供给终端的多播分组,并根据接入点提供; 通过网络接收组播数据的路由器,并将组播数据包发送到终端以接收组播数据; 以及移动控制服务器,其从所述管理部分获取所述终端的位置信息,向所述管理部件发送用于确定所述多播数据的接收的查询消息,以便在接收到所述查询消息时确认所述终端是否加入所述多播 并且在接收到加入组播的成员关系报告消息时,控制路由器和管理部分之间的隧道的设置,以发送成员报告消息。
