1. A method for multicast packet communication by mobile entities using a plurality of radio access networks (RANs) comprising the steps of:
- receiving a multicast message at at least one router;
determining multicast capabilities at at least one network attachment point of a mobile entity (ME);
selecting an optimal multicast delivery mode for delivering the multicast message to the ME at the at least one network attachment point; and
delivering the multicast message to the ME at the at least one network attachment point according to the selected delivery mode.

Abstract
A method for multicast packet communication by mobile entities (113) using one or more radio access networks (RANs) (107, 109, 111) that include receiving a multicast message at a router (105) and then determining multicast capabilities of a mobile entity (ME) (113). An optimal multicast delivery mode is selected for delivering a multicast message to the ME (113) at the radio access network (107, 109, 111). The multicast message is then delivered to the ME (113) at the radio access network (107, 109, 111) according to the selected delivery mode.

23. A method for multicast packet communication by a Mobile Entity (ME) using a plurality of network comprising the steps of:
-
determining multicast capabilities at at least one network attachment point of a mobile entity (ME); notifying multicast capabilities to a mobile multicast (MM) server; and configuring the ME for receiving multicast packet according to a selected multicast delivery mode. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A method for selecting a multicast delivery mode for the network attachment point of a mobile entity (ME) comprising the steps of:
-
sending a request to a mobile multicast (MM) server for sending multicast packet of a first multicast group address both within a multicast-in-unicast tunnel and a multicast-in-multicast tunnel to a mobile entity (ME); receiving parameters from the MM server for using a multicast-in-multicast tunneling mode having a multicast group address; processing at least one multicast packet received in a unicast tunnel; sending the at least one multicast packet by the MM server in a tunneled manner using the multicast group address; detecting if the at least one multicast packet in a multicast tunnel is received; requesting the MM server to stop multicast-in-unicast tunneling and using only a multicast-in-multicast tunneling process if the at least one multicast packet is received; detecting if the at least one multicast packet in a multicast tunnel is not received; requesting the MM server to stop multicast-in-multicast tunneling and using only a multicast-in-unicast tunneling process if the at least one multicast packet is not received; providing a selected multicast delivery mode by the MM server based on the receipt of a multicast tunnel; and processing the at lest one multicast packet according to the selected multicast delivery mode. - View Dependent Claims (36, 37, 38, 39, 40)
