    • 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.
    • 基于网络的移动多播系统及其方法技术领域本发明涉及一种移动多播系统及其方法,并且更具体地涉及基于网络的移动多播系统及其方法。 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多播系统,包括:接入点,其通过无线信道与接入网络内的移动终端进行通信,获得终端的第2层地址,并且提供 获得的终端的第2层地址; 管理部分,用于控制接入点中包括的每个终端的切换,发送要提供给终端的组播分组,并根据接入点提供; 路由器,通过网络接收组播数据,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,其从管理部件获得终端的位置信息,向每个管理部件发送用于确定组播数据的接收的查询消息,以便在接收到查询消息时确认终端是否加入组播 并且当接收到用于加入组播的成员报告消息时,控制路由器和管理部件之间的隧道的设置,用于发送成员资格报告消息。
