Push-to-Talk over Cellular W hat is it ? ITU-T A form of communication that allows users to engage in Wireless Network immediate communication Member A Member E with one or more users, providing a “ walkie- talkie” like P2P and group service. Member B Member D Member C The communication is half-duplex o Right-to-S peak amongst different participants is controlled o The receiving participants hear the sender's voice either by Auto o Answer without any action on their part, or by Manual Answer , i.e. being prompted/ alerted and accepting the call before hearing the sender's voice. PoC utilizes the Group Management and Presence enablers to o support Group List, Access Lists, and Presence. I TU-T W orkshop “NGN and its Transport Netw orks“ Kobe, 2 0 -2 1 April 2 0 0 6 1 3
