1. A method for wireless multicast downloading of data to mobile devices comprising steps of:
- determining multicast capabilities of the mobile devices;
assigning each of the mobile devices to one of a plurality of subgroups of the mobile devices, subgroup assignment of the mobile devices being based upon at least one of the multicast capabilities of the mobile devices; and
determining how to download the data or what type of data to download to the mobile devices based upon the subgroup assignment.

Abstract
A method for wireless multicast downloading of data to mobile devices including steps of determining multicast capabilities of the mobile devices; assigning each of the mobile devices to an individual one of a plurality of subgroups of the mobile devices; and determining how to download the data or what type of data to download to the mobile devices based upon the subgroup assignment. The subgroup assignment of the mobile devices is based upon at least one of the multicast capabilities of the mobile devices.

13. A method for wireless multicast downloading of data to a mobile device comprising steps of:
-
requesting download of the data from a service provider to the mobile device by a user of the mobile device;
sending multicast capability information regarding the mobile device to a management server at the service provider;
grouping identification of the mobile device in a group or subgroup with at least one other mobile device requesting a similar download, the group or subgroup being organized based upon at least one common multicast capability in the multicast capability information of the mobile devices; and
determining how to download the data to the mobile device based upon its grouping and the at least one common multicast capability. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A system for managing multicast downloading of data from a service provider to mobile devices having different multicast reception capabilities, the system comprising:
-
means for determining information regarding the multicast reception capabilities of individual ones of the mobile devices and transmitting the information to a management server at a service provider;
means for assigning the mobile devices to subgroups by the management server based upon commonality of information in the multicast reception capabilities information of the mobile devices; and
means for transferring the data to the mobile devices in each subgroup, the means for transferring being adapted to individually configure data transmission for each of the subgroups based upon common or similar information in the multicast reception capability information for the mobile devices for that subgroup. - View Dependent Claims (26, 27)

28. A method for wireless multicast downloading of data to a mobile device comprising steps of:
-
providing a device having a management tree with a plurality of intermediate nodes, wherein the intermediate nodes are based upon different multicast transmission subgroupings;
delivering data by multicast transmission from a first server to a first one of the intermediate nodes of the device based upon the multicast transmission subgrouping of the first intermediate node and a multicast subgrouping of the data transmission, wherein the data is constrained in the intermediate node until released by an authorized entity; and
releasing the data from the intermediate node to an actual node of the device by the authorized entity for use of the data by the device. - View Dependent Claims (29)
