Abstract
Systems and methods for enhancing broadcast/multicast services in telecommunication networks are disclosed. A multicast router is provided between a network node, such as an SGSN or GGSN, and a radio access network. A multicast transport address can be provided to send packet data from network devices to the radio network in a multicast fashion. The multicast transport address works with multicast equipment, such as multicast routers, to reduce the burdens of sending data in a broadcast or multicast fashion to mobile nodes.
