Abstract
IP multicast allows the efficient support of group
communication services. The increase in the
use of multicast has also triggered the need for
supporting IP multicast in mobile environments.
It is necessary to consider current unicast mobility
management solutions in IP-based networks to
smoothly extend multicast services to mobile users. Proxy
Mobile IPv6 is a network-based mobility
management solution, where the functionality to support
the terminal movement resides in the network.
Recently, a base solution has been adopted for supporting
multicast in PMIPv6. Nevertheless,
this solution has not special features to optimize
performance during handovers and this can cause
disruptions in the reception of multicast traffic by the
mobile terminals. This paper proposes and
evaluates RAMS, an extension to the PMIPv6 protocol for
accelerating the multicast service delivery
to mobile terminals after handovers. We explore the
performance gain obtained by RAMS,
compared against the base solution, using two different
radio access network scenarios: 3GPP UTRAN
and LTE.
