Abstract
Approaches for resource efficient multicast communications in mobile satellite systems are provided. A wireless gateway is configured to encapsulate multicast signaling messages received from participating remote terminals. The encapsulation is compatible with the core network of the system, whereby the signaling is passed through the core network undetected. The signaling is received by a multicast gateway, and provides necessary IP and port addressing information for the multicast gateway to encapsulate the multicast session data in a manner compatible with the core network. Upon receiving multicast session data from a multicast server, the multicast gateway replicates and encapsulates each data packet with IP and port addressing for each participating remote terminal, which is also passed through the core network undetected. The wireless gateway receives the replicated data packets, and based on the encapsulation information, transmits each data packet via a broadcast transmission to each cell wherein participating terminals are located.
