Zusammenfassung:An access point, a layer 2 switch, and multicast handover supporting method using the access point and the layer 2 switch are provided. According to the method of supporting multicast handover, when a mobile node is handed over from one cell to another while being provided with a multicast service in a wireless mobile communication network, the L2 switch performs multicast traffic routing in response to reception of MAC address information and multicast service source and group information from the access point. Hence, multicast traffic can be supported to be fast and seamlessly handed over within layer 2 network equipment.
