20110092172 | Private Communication in a Push to Talk Over Cellular Network - A method of sending a communication to a Participant in a PoC Group Session. A PoC client sends a SIP REFER message to a PoC participating Server, which forwards it to a PoC Controlling Server. The SIP REFER message comprises an identity of a target Participant in the Group Session and a message content. The PoC Controlling Server creates a SIP MESSAGE method, the MESSAGE addressed to the target Participant and including the message content. The SIP MESSAGE is then sent to a target Participating Server that serves the target Participant.
