<p>A system provides for traffic offloading in a Public Safety communication system, from a congested radio access network cell to one or more alternate wireless networks. The system includes multiple user equipment (UEs), each a member of a same communications group, and a services network element configured to receive information comprising an identifier of the communications group, an identifier of each UE of the multiple UEs, and an identifier of a cell of a primary network where each UE resides; determine that a primary network cell is congested, and then responsive to this, determine a subset of the multiple UEs that are members of the communications group, reside in the congested cell, and are capable of being served by one or more secondary networks; and instruct the subset of UEs to offload their communications group traffic to the one or more secondary networks, wherein the instruction is with regard to hand off to the one or more alternate networks, or else only to offload the data traffic associated with the communications group.</p> |
