Abstract
Embodiments provide efficient multicast handover for content delivery to client devices in multi-carrier communications systems. For example, client devices in a transport craft can consume a media channel offering via a first carrier during transport through the communications system. Embodiments can establish respective multicast groups for the media channel offering in at least the first carrier and a subsequent second carrier, and can notify the craft of the multicast groups prior to the craft being serviced by the second carrier. Such pre-notification can permit multicast handover of the media channel offering from the first carrier to the second carrier in a manner that avoids typical handover-related. For example, embodiments can direct multicast delivery of the media channel offering to the craft in accordance with the first multicast group while being serviced by the first carrier and in accordance with the second multicast group while being serviced by the second.
