The disclosure is directed to group communications over multimedia broadcast/multicast services (MBMS). An aspect receives location information for each of a plurality of multicast-enabled target user devices, determines one or more area polygons based on the location information, each area polygon comprising a list of network components configured to provide multicast services to a subset of the plurality of multicast-enabled target user devices, and stores the one or more area polygons. An aspect receives a call request to establish a group call among a plurality of multicast-enabled target user devices, identifies one or more area polygons corresponding to the plurality of multicast-enabled target user devices, and provides a list of network components obtained from the one or more area polygons to one or more broadcast multicast service centers (BM-SCs) serving the plurality of multicast-enabled target user devices. |
