Abstract
A method for establishing multicast PoC communication is disclosed. To establish multicast PoC communication, a multicast-join process will be coupled with a PoC session setup process, and the PoC server will function as a multicast content server, to multicast PoC communications to the PoC session participants. For example, when a party initiates a PoC session, the PoC server may acquire a multicast flow-ID from a multicast session manager, and the PoC server may convey that multicast flow-ID to each participant within the PoC session setup signaling. Upon receipt of the multicast flow-ID, each participant may then engage in signaling with the multicast session manager, to join the associated multicast group. And the multicast session manager may direct the PoC server to begin multicasting the associated flow to the group members, which the PoC server will do once it begins receiving PoC bearer data from one of the PoC session participants.
