Method and system for delivering media to a plurality of mobile devices in a cell with a group transport function

A system for delivering media to a plurality of mobile devices in a communications group, the system comprising:

• an infrastructure device implementing a group transport function (GTF) and connected to a plurality of cells that serve the plurality of mobile devices within the communications group, wherein each cell includes a point-to-point resource and at least one cell includes a point-to-multipoint resource;
• and
• another infrastructure device implementing an application function, the application function providing the media to the GTF;
• wherein the GTF receives a plurality of inputs from the application function and the plurality of cells, the plurality of inputs including at least capabilities of each mobile device in the group to receive the media using point-to-multipoint media transport and capabilities of each cell in the plurality of cells to deliver the media using point-to-multipoint or point-to-point transport, and wherein the GTF determines, for each mobile device within the communications group and based on the plurality of inputs and one or more of a role, in the communication group, of a group member associated with the mobile device and a type of an incident for which a group member associated with the mobile device is involved, whether to deliver the content to the mobile device using point-to-multipoint or point-to-point media transport;
• wherein the GTF initiates allocation of a set of resources in each cell to transport media to each mobile device in the group using the determined media transport for that mobile device and wherein initiating allocation of a set of resources comprises initiating allocation of at least one Multicast Broadcast Multimedia Service bearer;
• wherein the GTF replicates media for delivery to the plurality of mobile devices over the allocated resources using the determined media transport for each mobile device.

An infrastructure device, the infrastructure device comprising:

• a processing device that is configured to implement a group transport function (GTF) performing:
• receiving media for delivery to a plurality of mobile devices in at least one group, wherein the plurality of mobile devices are served by a plurality of cells, wherein each subscriber uses at least one mobile device, wherein each mobile device is wirelessly connected to one of the cells, wherein each cell is to connected to at least one network;
• receiving a plurality of inputs comprising at least capabilities of each mobile device in the group to receive the media using point-to-multipoint media transport and capabilities of each cell in the plurality of cells to deliver the media using point-to-multipoint or point-to-point media transport;
• applying a set of policy rules to the plurality of inputs to determine, for each mobile device in the group, whether to deliver the content to the mobile device using point-to-multipoint or point-to-point media transport, wherein the policy rules are based on one or more of a role, in the communication group, of a group member associated with the mobile device and a type of an incident for which a group member associated with the mobile device is involved;
• initiating an allocation of a set of resources in each cell to transport the media to each mobile device using the determined media transport for that mobile device, wherein initiating an allocation of a set of resources comprises initiating allocation of at least one Multicast Broadcast Multimedia Service bearer;
• and
• replicating the media for delivery to the plurality of mobile devices over the allocated resources across at least one group using the determined media transport for each mobile device.
