A method, device, and system for establishing and maintaining a multicast group call. The method includes monitoring one or more link parameters for each of a plurality of communication devices associated with the multicast group call. The method further includes selecting, for each of the plurality of communication devices, a sector from a plurality of permitted sectors, the selected sector providing an associated highest signal strength for the communication device and forming a multicast communication zone based on the selected sectors. The method further proceeds with calculating a signal to interference plus noise ratio (SINR) for each communication device based on the formed multicast communication zone, identifying a communication device with a lowest SINR, updating a spectral efficiency metric relative to the formed multicast communication zone based on the lowest SINR, and establishing the multicast group call when the updated spectral efficiency metric meets a minimum expected spectral efficiency metric. |
